Ireland CCA 2013 Payment Claim Notice & Schedule Workflow

A Payment Claim Notice from a subcontractor lands on your desk. It is dated, it claims a sum to two decimal places, it cites measurement against the contract and a stage of work reached, and from the payment claim date stamped on it you have twenty-one days to deliver a written Payment Schedule in response. That clock — and the work that has to fit inside it — is the spine of the Ireland CCA 2013 payment claim notice workflow this guide walks through.

The Construction Contracts Act 2013 (Act 34 of 2013, in force 25 July 2016) governs the payment cycle on every Irish construction contract worth €10,000 or more, main contracts and sub-contracts alike. The Act mandates a 30-day payment cycle from the payment claim date, requires the payee (typically the subcontractor) to serve a Payment Claim Notice (PCN) stating the amount claimed and how it is calculated, and obliges the responding party to deliver a written Payment Schedule setting out the amount proposed to be paid and the basis for any difference from the claim. Section 4 of the Construction Contracts Act 2013 is the locus of the response duty: section 4(3)(a) requires the responding party to deliver a response to the payment claim notice not later than 21 days after the payment claim date.

The position when a principal contractor misses that 21-day window is the part of CCA 2013 most often misstated, including in older content written before the post-2024 Irish High Court position settled in. Missing the 21 days does not automatically crystallise the claimed amount as a notified sum payable by default. Irish courts have explicitly refused to read the UK "smash and grab" default-payment consequence into CCA 2013 — a procedural failure does not, on its own, hand the subcontractor the full claimed figure. What the missed window does cost is the unilateral withholding posture: any reduction the principal wants to defend has to be on the record by the end of the 21 days, and where it is not, the dispute proceeds to statutory adjudication on the merits via the Construction Contracts Adjudication Panel, with the subcontractor still required to prove value rather than simply collect.

The rest of this article is a principal-side walk-through built around that 21-day clock. We cover what the Payment Schedule has to state under CCA 2013, the line-by-line assessment work the certified figure rests on, retention treatment on the Schedule and on the GL, the downstream eRCT Payment Notification and reverse-charge VAT flow that the certified amount drives, the practical consequences of a late or short response under the post-2024 Irish position, the Construction Contracts Adjudication Panel route if the matter escalates, and the points where the Irish regime diverges from the UK pay-less cycle a QS or commercial manager working across both jurisdictions has to keep separate. The Schedule is not just the response document to one subbie — it is the upstream record that drives the eRCT Payment Notification, the Deduction Authorisation, the subcontractor's reverse-charge VAT invoice, and the figures that land in the project's monthly cost-value reconciliation. The assessment work has consequences well beyond the contractual relationship.

What the Payment Schedule must state under CCA 2013

Section 4 of the Act is short on what the response document has to look like and precise on what it has to contain. The Payment Schedule must state the amount the responding party proposes to pay — the certified amount — and, where that figure is less than the amount claimed in the PCN, the basis for the difference. Those are the two statutory loads the document has to carry. The form, the layout, the headers, the level of detail, the medium: the Act prescribes none of these. A defensible Payment Schedule is built on what custom and case law have come to expect rather than on a statutory template.

In practice, the Payment Schedules Irish quantity surveyors issue carry the same components whether the contract is a CWMF public-works form, a bespoke commercial agreement, or a back-to-back sub-contract under a JCT- or NEC-flavoured main contract. A workable Schedule clearly identifies the underlying contract and the PCN it responds to, records both the payment claim date and the issue date of the Schedule itself, and runs a line-by-line valuation of work claimed against work assessed. Variations and dayworks are accounted for separately from measured work — variation entries cross-referenced to the variation register and dayworks to the underlying timesheets and materials evidence. Retention is shown as a discrete deduction at the contract percentage rather than netted into the line valuations. Prior-period payments are rolled forward so the period certification ties to the cumulative valuation. Set-offs and counterclaims — back-charges, contra-charges for defective work, third-party costs the principal has incurred for the subbie's account — are surfaced inside the Schedule with the basis stated against each. The certified figure carries through to the bottom line as the post-retention, post-set-off amount the principal proposes to pay.

The single-document model is one of the points where the Irish regime diverges from UK practice in a way that matters at the document level. There is no separate "pay less notice" to issue alongside the Payment Schedule under CCA 2013. The Schedule itself is the single instrument that both certifies the sum and discharges the duty to give reasons for any reduction from the claim. Importing UK terminology into the Irish Schedule — labelling reductions as "pay less" deductions, treating the document as an Application for Payment certification rather than a Payment Schedule response — is a credibility cost in front of an Irish subcontractor and, downstream, an adjudicator. The vocabulary belongs to the regime; mixing them up signals that the principal's commercial team is running UK habits on an Irish contract.

A handful of form-level practicalities round out a Schedule that holds up to scrutiny. The document is signed or formally issued by an authorised representative of the principal — the QS, commercial manager, or contract administrator named in the contract. Delivery uses a method that creates a record: the contract typically prescribes (registered post, email to a named address with read receipt, hand delivery against signature) and the Schedule is delivered that way. The issue date is stamped clearly on the face of the document so the 21-day calculation is unambiguous to both sides — the payment claim date plus 21 days is the deadline, and a Schedule that arrives one or two days late on a counted-back-from-receipt basis is a fact pattern that ends up in front of an adjudicator more often than it should.

The corollary that runs through everything else in this guide: any reduction from the claimed amount that is not surfaced inside the Payment Schedule cannot be silently withheld from payment afterwards. The post-2024 Irish High Court line is that the principal's reasoning has to be on the record by the end of the 21 days, even though the claimed amount itself does not automatically crystallise on a missed Schedule. A back-charge raised after the Schedule has issued is harder to defend than the same back-charge surfaced inside the Schedule with a contra-charge line, a brief description, and a value. The 21 days is the window for putting the principal's commercial position on paper; once the window closes, the Schedule that issued — or did not — is the document the dispute is fought on.

Working the line-by-line assessment of the Payment Claim Notice

The assessment work starts at the document set the PCN sits on top of. A serious Payment Claim Notice does not arrive as a bare cover letter and a number — it arrives with measurement annexes against the contract bills or schedule of rates, marked-up drawings or as-built measurement records, dayworks sheets with timesheets and materials dockets, and a covering valuation reconciling the period claim to the cumulative claim. Sitting alongside it on the QS's desk are the prior Payment Schedules issued under the same contract, the contract bills of quantities or pricing schedule, the contract drawings and specifications, and the variation register — every variation instructed to date, with the relevant compensation events, daywork orders, and any quotations submitted and accepted. The line-by-line reconciliation runs the PCN against this stack rather than against the QS's recollection of the project.

Re-measurement of progressed work against the priced bills or schedule of rates is the first substantive move. The subcontractor's measurement is a claim, not a determination — the QS works through the major elements line by line, compares the quantities claimed to what is observable on site or recorded on the latest as-built drawings, and adjusts where the claim runs ahead of progress. Prior-period roll-forward is the next move and is mechanical rather than judgemental: interim payments are cumulative, the certified figure on each Schedule is a cumulative valuation, and the period certification is the cumulative figure less prior certifications. The arithmetic has to tie. Variations are valued under the contract's own variation rules — CWMF public-works contracts, bespoke commercial forms, and sub-contracts back-to-back with NEC or JCT main contracts each have their own machinery, and the QS has to apply the rules of the contract in front of them rather than a general default. Dayworks are priced under the contract's dayworks regime against the timesheets and materials dockets that support each entry; an unsupported daywork entry is a candidate for set-off in the Schedule until the records are produced. Materials on site (unfixed materials) are treated under the contract clauses on title transfer, separate storage, insurance, and the risk position.

Set-off and counterclaims have to come out into the Schedule rather than sit silently behind the certification. Defective work the principal has had to remedy at its own cost, delay damages where the contract gives a clear entitlement, back-charges for principal-supplied items the subbie has consumed, third-party costs incurred for the subbie's account — every contra-charge belongs on the Schedule as a clearly described line with a value, even if the underlying entitlement is contested. The Schedule is the single channel for putting the principal's reasoning on the record within the 21-day window; reductions raised inside it can be defended at adjudication on the merits, while reductions sprung after issue are harder to argue.

The precondition for line-by-line assessment of any volume is getting the source documents into a structured workbook the QS can drive the reconciliation through. A measurement annex on a sizeable contract runs to dozens or hundreds of pages of structured PDF — bill references, item descriptions, units, claimed quantities, claimed rates, claimed values — repeated across every section of the priced bills. Re-keying that material is where assessment time is lost; a workbook that already mirrors the contract's bill structure is what makes line-by-line review feasible inside the 21 days rather than an aspiration that gets compressed into the last 48 hours of the window. Our extraction tool will extract Payment Claim Notice and measurement annexes into a structured assessment workbook — Excel or CSV that mirrors the bill structure, with each measurement line as its own row and the source page recorded for verification — so the QS spends the 21 days on the measurement and value judgement the Schedule rests on, not on data entry. The judgement is still the QS's; the workbook is the substrate the judgement runs on.

The certified figure that comes out of this assessment has a downstream life beyond the Schedule itself. It is the figure that feeds the monthly cost-value reconciliation workbook the certified figures feed into for the project's commercial reporting, and it has to tie to the figure that lands in the eRCT Payment Notification, the subbie's reverse-charge invoice, and the project ledger entries. Inconsistency between the Schedule's valuation and the CVR ledger is the kind of audit-trail break that turns into questions at year-end, and avoiding it begins with running the assessment off a single workbook that the Schedule, the CVR, and the eRCT submission all reference back to.

Retention on the Payment Schedule

Retention is contract-driven, not statutory under CCA 2013. The Act sets the response and payment cycle; the contract sets the percentage, the release pattern, and the rules around any retention bond that substitutes for the deduction. Most Irish construction contracts hold 5% retention against the gross valuation, with halves released at practical completion and at the end of the defects period — a pattern that shows up in CWMF public-works contracts and in the bespoke commercial forms most main contractors use with their subcontract chain, but with enough variation in the specifics (defects period length, half-versus-full release at PC, conditions on release) that the contract clauses are the authority on each project rather than a category default. A Schedule that applies 5% by reflex without checking the clause is the kind of small slip that breeds a contra-claim.

On the Schedule itself, retention is a separate line at the contract percentage rather than netted into the line valuations. The gross valuation shows; retention deducts; the certified amount is the post-retention figure that goes through to the eRCT Payment Notification and ultimately the payment to the subbie. Showing retention as its own line keeps the cumulative position legible — at any point in the contract, summing the retention deductions across every issued Schedule gives the cumulative retention balance held against that subcontractor, and the figure ties to the retention sub-ledger without manual reconciliation. It also keeps the reasoning visible if a retention adjustment is needed mid-contract — for example where the contract substitutes a retention bond for the cash deduction at a defined trigger, the Schedule line drops to zero and the bond reference is recorded in the working papers.

The general ledger treatment follows the Schedule. Retention payable sits under accruals on the principal's balance sheet for the duration of the holding period — recorded in a dedicated sub-ledger by subcontractor and project, with the contract clauses governing each release, the practical completion date once issued, and the defects period end-date scheduled forward. The release events at practical completion and at the end of the defects period are the points where the cash actually leaves; the sub-ledger is what makes those events triggerable on the right date for the right amount, against the right party, without manually reconstructing five years of certifications.

The cross-project picture is where retention administration actually fails for most principal contractors. A busy contractor is holding retention against dozens of subcontractors across several live projects and several recently-completed projects whose defects periods are still running. Release events sit on the calendar across years rather than months, and they typically arrive without prompting from the subcontractor, who may have moved on to other work and forgotten to chase. Tracking retention release dates centrally — with the underlying contract clauses, the practical completion date, the defects period length, and the calculated release date all visible from a single workbook — is what stops releases from slipping or being missed entirely. The mechanic carries broadly across jurisdictions even though the contract forms differ, and there is published thinking on tracking subcontractor retention release across projects (UK reference, broadly carries to Ireland with bespoke-form caveats) that an Irish principal can read with the form-specific caveats in mind: the JCT and NEC release triggers in the UK reference do not match the CWMF or bespoke-form triggers in Ireland one-for-one, but the cross-project tracking discipline transfers cleanly.

From certified amount to eRCT Payment Notification and reverse-charge VAT

Once the Payment Schedule has issued, the certified amount — not the claimed amount in the PCN — is the figure that drives every downstream tax document. The Schedule is the upstream record; the eRCT Payment Notification, the Deduction Authorisation, the subbie's invoice, and the principal's VAT3 self-accounting all key off the same certified figure. A common operational error in this chain is mis-keying the gross figure into the eRCT Payment Notification — typing the claimed amount instead of the certified amount — and then having to back out the wrong Notification with a fresh submission once the subbie queries the deduction. The discipline is to move the certified figure from the Schedule into the eRCT submission verbatim, with the Schedule open alongside the eRCT screen.

The eRCT flow itself is a sequence of submissions on the Revenue Online Service (ROS). The principal logs into ROS, opens the eRCT system, and submits a Payment Notification stating the contract reference and the gross payment proposed — the certified amount from the Schedule. Revenue returns a Deduction Authorisation specifying the rate to be deducted at source: 0%, 20%, or 35% based on the subcontractor's RCT status with Revenue (which is determined by the subbie's own compliance history, not by anything the principal does). The rate applies to the certified amount, not the claimed amount. The Deduction Authorisation has to be in hand before the payment runs; paying the subbie before submitting the Notification is an RCT compliance breach exposing the principal to penalties and to liability for the deduction Revenue would have authorised.

With the Deduction Authorisation in hand, the subcontractor issues a tax invoice for the certified amount with the reverse-charge declaration on the face of the invoice — the standard wording is "VAT on this supply is to be accounted for by the principal contractor". The principal does not pay VAT to the subbie on construction services covered by the reverse-charge regime. Instead, the principal self-accounts for VAT on the VAT3 return at the construction services rate — 13.5% applies under the two-thirds rule for most principal-to-subcontractor arrangements, where the value of the materials supplied with the service does not exceed two-thirds of the total contract value. The output VAT goes in T1 on the VAT3 and the offsetting input credit goes in T2 in the same period, subject to the normal recovery rules; the cash effect is neutral, but the return entries have to go through. Skipping the self-account because the cash effect is zero is a VAT compliance failure that surfaces on Revenue audit, and the contemporaneous record of the eRCT Payment Notification, Deduction Authorisation, and reverse-charge VAT invoice the certified amount then flows into is what evidences the position taken on each subbie payment.

The full document chain reads as a single audit trail: PCN → Payment Schedule (sets the certified amount) → eRCT Payment Notification (gross = certified amount) → Deduction Authorisation (rate at source applied to certified amount) → subbie invoice with reverse-charge declaration (face value = certified amount, VAT not charged) → principal pays the subbie net of the RCT deduction within the 30-day cycle from the payment claim date → VAT3 self-accounts at 13.5% with offsetting input credit. Every step ties back to the certified figure on the Schedule, which is why the Schedule is more than a contractual response document — it is the source record that fixes every downstream entry.

A few operational specifics matter for keeping the chain clean. The eRCT Payment Notification has to be submitted before payment to the subcontractor; it cannot be submitted after the fact to retrospectively cover a payment already made. The Deduction Authorisation is valid only for the specific contract reference and gross amount notified — it does not roll forward to subsequent payments under the same contract automatically, and any change to the certified amount (for example a corrected Schedule following an error caught after issue, or a credit note from the subbie reducing the amount due) requires a fresh Notification rather than an adjustment to the original. Where the eRCT and the Schedule fall out of step on the gross figure, the cleaner remedy is almost always to reissue the smaller document — corrected Schedule or fresh Notification — than to defend a mismatch through to year-end audit. The per-payment Notifications then aggregate into the monthly RCT Deduction Summary the principal must reconcile and amend on ROS before the 23rd to avoid silent acceptance, which is the period-end checkpoint where any mismatch between Schedule and Notification surfaces if it has not already been corrected at source.

Missing the 21 days: the Irish position in 2026

Section 4 of CCA 2013 imposes the duty to deliver a Payment Schedule within 21 days of the payment claim date. What it does not impose, on its face or as Irish courts have read it, is automatic crystallisation of the claimed amount into a notified sum payable by default if the principal misses the window. The Irish High Court has refused — across a settled line of decisions surveyed in 2024 to 2026 commentary from the major construction-disputes practices, including Arthur Cox, Addleshaw Goddard, Eversheds Sutherland, Philip Lee, and Pinsent Masons — to read the UK Construction Act 1996 "smash and grab" default-payment consequence into the Irish statute. The Irish position is the duty-without-default-crystallisation reading: the principal owes the response, and missing it has consequences, but the consequences are not automatic transfer of the full claim to the credit of the subcontractor.

What the missed window actually costs the principal is the right to withhold without putting reasoning on the record. Inside the 21 days, a Payment Schedule that surfaces a contra-charge with a brief description and a value sets the principal's position on the merits and discharges the duty under section 4. Outside the 21 days, the same contra-charge is a position the principal still takes, but it is taken without the procedural advantage of having set the figure inside the statutory window. The dispute then proceeds to statutory adjudication on the merits — the subcontractor still has to prove value, the principal can still defend the certified figure, and the figure that comes out of adjudication can be higher or lower than the claimed amount depending on what the parties prove. The exposure is real, but it is exposure to adjudication on merits, not to automatic crystallisation of the full claim.

The distinction matters because the wrong consequence travels easily. An Irish QS who has worked on UK projects, a commercial manager whose training material was UK-flavoured, or anyone using cross-jurisdictional templates from the New Zealand CCA 2002 or Singapore SOPA traditions can carry over the smash-and-grab consequence by reflex. Under the UK regime, missing the Pay Less Notice window has produced binding adjudication awards for the full notified sum on procedural failure alone — the line of cases stretches back through Grove Developments and onward and has produced its own body of practice around interim certifications and what counts as a valid notice. None of that line of authority applies in Ireland. The Irish case law has gone the other way and has stayed there.

That said, the Irish "no smash and grab" position is not a substitute for hitting the window, and a principal that consistently runs late on the Schedule is signalling something to its subcontractor base. Disputes that should have been resolved at the Schedule end up at adjudication; adjudicator fees accumulate against both parties regardless of who prevails on the merits; the working relationship with the subcontractor erodes; and the principal's commercial team builds a reputation for procedural sloppiness that travels with the firm. The procedural win the Irish position offers — protection against automatic crystallisation — is the floor, not the ceiling. The commercial management of the relationship still rests on issuing a Schedule that sets the figure, with the reasons stated, inside the 21 days.

There is one other statutory consequence that runs alongside the Schedule duty and that operates independently of any adjudication. CCA 2013 gives the subcontractor a statutory right to suspend performance where the principal has not paid an amount due in full by the 30-day payment cycle. The notice required is seven working days' written notice of intent to suspend, and on expiry the subcontractor can lawfully stop work without breaching the contract. Suspension does not require an adjudicator's award — the right exists on the face of the statute against any unpaid amount that is due. For a principal sitting on a marginal contra-position with the 21 days expired and the 30-day payment cycle approaching, the suspension exposure is often the more immediate operational concern than the adjudication exposure: an adjudication takes weeks to run, but a suspension can take a programme off-track within ten working days of an unpaid notified sum sitting past its 30-day deadline.

The Construction Contracts Adjudication Panel route

Either party to a construction contract within the scope of CCA 2013 has the right to refer a payment dispute to adjudication at any time, with adjudicators drawn from the Construction Contracts Adjudication Panel maintained under the Act. The Panel is administered through the office of the Chairperson — the public-facing entry point is adjudicator.ie, where the Notice of Intention to Refer is filed and the appointment process runs. The route does not require either party's agreement to engage; the statutory right is unilateral. A subcontractor whose Schedule has been short-paid, or a principal facing a Schedule it cannot persuade the subbie to revise, can refer at any time without preconditions other than that the dispute concern a payment under a contract within the Act's scope.

The procedure runs through a defined sequence. The referring party files a Notice of Intention to Refer, and an adjudicator is appointed (either by agreement of the parties or, more often, by the Chairperson's office where the parties have not agreed within seven days). The referring party then submits a Referral setting out its case with supporting documents; the responding party submits a Response within the timetable the adjudicator sets; further submissions, requests for information, and any meetings or site inspections happen on the adjudicator's directions. The default decision timetable is 28 days from the date the dispute is referred to the adjudicator, extendable by up to 14 days with the referring party's consent and longer only with both parties' agreement. The compressed timeline is the defining operational feature of the route: a principal that is named in a Notice and given seven days to respond to a Referral does not have time to assemble a case from scratch.

The evidence pack the principal typically submits looks similar across cases. The Payment Schedule itself is the spine — the document the principal issued inside the 21 days, with the certified amount and the basis for any difference from the claim recorded on it. The underlying measurement workbook and supporting documents, in the form they were used to derive the Schedule, are the substantive defence of the figure: the line-by-line valuation, the variation register entries that fed into the certification, the dayworks records and timesheets, the materials evidence. The contract documents — the executed form, special conditions, bills of quantities or schedule of rates, programme — sit alongside as the framework against which the certification is measured. Prior period Schedules and the corresponding PCNs in the same contract evidence the running cumulative position. Contemporaneous correspondence — RFIs and responses, change-management correspondence, the principal's reasoning trail for the contra-charges raised on the Schedule — closes the evidence pack. The Schedule that issued inside the 21 days is the spine; the working papers are what defends the figure on the merits.

The status of the adjudicator's decision is the structural feature of the regime that everyone has to plan around. The decision is binding on both parties pending final resolution by arbitration, litigation, or agreement of the parties. Whatever figure the adjudicator certifies is payable on the timeline the decision sets, and the loser pays in the meantime — there is no automatic stay pending an arbitration or court challenge. Enforcement is straightforward through the High Court where the decision is not complied with voluntarily, and the courts have consistently enforced adjudicators' decisions absent a clear procedural defect or jurisdictional error. The adjudication is not the final word on the underlying dispute; arbitration or litigation can revisit the merits later. But the cash position the adjudication sets is the cash position the parties operate on until that later determination, and the time and cost of going behind the adjudication is not trivial.

The cost dynamic shapes how parties run the process. Each party bears its own legal and expert costs unless the adjudicator orders otherwise — the default is no cost-shifting. The adjudicator's own fees are typically split between the parties unless the decision allocates them differently, with the basis usually tied to the conduct of the parties or the substance of the outcome. Even a successful adjudication is expensive in time and fees relative to handling the matter inside the 21-day Schedule window — and it is expensive on both sides regardless of who prevails. That cost differential is the strongest commercial argument for hitting the Schedule window: an Irish principal that issues a clear, defensible Schedule inside 21 days settles most disputes at the Schedule and reaches adjudication only on the genuinely contested matters. The principal that consistently misses the window invites adjudications it would not otherwise face, and pays adjudicator fees on each one whether or not the certified figure stands.

Where the Irish regime diverges from the UK pay-less cycle

For a QS or commercial manager who has trained on UK material, or who runs work on both sides of the Irish Sea, the Ireland-versus-UK contrasts are worth setting out cleanly so the wrong document or the wrong terminology does not drift across. The two regimes share the same instinct — interim certification with a procedural framework that pushes disputes into adjudication rather than into the courts — but they differ on terminology, on document model, on consequences of a missed window, and on the downstream tax flow.

Terminology first. What the UK regime calls an Application for Payment is in Ireland a Payment Claim Notice (PCN). What the UK regime calls a Pay Less Notice — the document that withholds against a Payment Notice or against the notified sum — is in Ireland the basis-for-difference content of the Payment Schedule itself. There is no separate pay-less instrument under CCA 2013; the Irish single-document model collapses what the UK splits between the Payment Notice and the Pay Less Notice into a single Schedule that does both jobs. The phrase "notified sum" is also used differently in the two regimes. In the UK, the notified sum is the figure that becomes default-payable on procedural failure to issue a valid Pay Less Notice in time. In Ireland, "notified sum" appears in CCA 2013 as the statutorily-defined amount in the response — it is descriptive of the Schedule's figure, not a default-crystallisation concept. Reading UK case law on notified-sum disputes against an Irish Schedule is reading two different things by the same name.

Timelines also diverge. The UK splits the response across a Payment Notice and a separate Pay Less Notice, each with its own contract-driven window running back from the final date for payment; the Irish regime collapses the equivalent into a single 21-day Payment Schedule window from the payment claim date, with the 30-day payment cycle running from the same trigger date. The consolidated Irish calendar is simpler than the UK equivalent, but it does not leave the principal a separate bite at putting reasoning on the record outside the 21 days.

Consequences of a missed window are where the two regimes diverge most clearly, as covered in the previous section. Under the UK regime, missing the Pay Less Notice window crystallises the notified sum by default and the smash-and-grab adjudication route enforces the full claimed figure on procedural failure alone — a body of case law that travels well-known territory through Grove Developments and successor decisions. Under the Irish regime, the missed window strips the principal's procedural posture but does not crystallise the claimed amount; the dispute proceeds to adjudication on the merits with the subcontractor still required to prove value. For a QS or commercial manager working between both regimes, this is the contrast it is most expensive to forget. There is published thinking on the UK Construction Act 1996 equivalent — assess an Application for Payment and issue a Pay Less Notice for readers who want the full UK cycle alongside this Irish walk-through.

The downstream tax flow is genuinely different and there is no clean read-across. The UK has CIS for construction tax deductions and standard VAT under the construction reverse-charge regime that came in in 2021, with the verification statuses, monthly CIS returns, and reverse-charge invoice mechanics that flow from those rules. Ireland has eRCT — submitted on ROS, with the Payment Notification, Deduction Authorisation, and 0%/20%/35% deduction-at-source mechanic covered earlier in this guide — and construction-services reverse-charge VAT at 13.5% under the two-thirds rule, self-accounted on the VAT3. The structural shape of the two regimes is similar enough to be confusing and different enough at the operational level that running them on autopilot from one regime into the other ends in compliance breaches in the second.

A final operational note that an Irish principal will recognise. The Payment Schedule cycle is one of several month-by-month compliance flows running in parallel for the same firm. The eRCT submissions and Deduction Authorisations have their own rhythm against each subbie payment; the VAT3 returns sit across the whole period; on the payroll side, the parallel Irish payroll-side compliance task — preparing the monthly CWPS schedule from construction payslips runs the construction industry pension and sick-pay contributions for direct site labour against the same period-end. The same source-document discipline that makes the Payment Schedule defensible — structured workbooks built from the underlying PDFs rather than re-keyed numbers — applies across the cluster. A principal that runs each of these flows off ad-hoc spreadsheets pieced together by hand is leaving compliance gaps; a principal that runs them off structured data extracted once from the source documents and reused across the workflows ends up with cleaner returns and an audit trail that holds up at year-end.
