Norway A-melding 2026: Foreign Employer Payroll Reporting Guide

The A-meldingen is Norway's unified monthly payroll and employer report, covering wages, forskuddstrekk (preliminary tax withholding), and arbeidsgiveravgift (AGA — the employer's national insurance contribution). Every employer with Norwegian-resident employees must submit it through Altinn by the 5th of the month following the wage payment. That obligation extends to foreign employers — a foreign company with even one Norwegian-resident employee on assignment or local employment is caught by the regime.

From 1 January 2026, three things changed at once. First, the separate skattetrekkskonto — the dedicated bank account in which employers had to ring-fence withheld tax — is abolished. Second, utbetalingsdato (the actual salary payment date) is now mandatory on every wage line. Third, withheld tax is paid directly to the Norwegian Tax Administration the working day after each salary run, rather than accumulating in the ring-fenced account for the bi-monthly transfer. The cash mechanic that Norwegian payroll has run on for decades has shifted, and most existing English-language explainers either pre-date the change or cover only one slice of it. This is the unified Norway A-melding foreign employer 2026 reference, written for the payroll-responsible practitioner reading in English.

A brief terminology note before going further: the A-meldingen replaced five separate Norwegian payroll forms in 2015 (lønns- og trekkoppgave, terminoppgave, melding til arbeidstakerregisteret, the wage statistics return to Statistisk sentralbyrå (SSB), and the OTP/pension-scheme report). Internal documents and audit workpapers written before 2015 still refer to the legacy sub-forms; the modern A-melding consolidates all five into one monthly submission shared between Skatteetaten, NAV, and SSB.

The three 2026 changes, unpacked

In operational order: from 1 January 2026 employers stop maintaining the skattetrekkskonto, start transferring withheld tax to Skatteetaten the working day after each salary run, and start populating utbetalingsdato on every wage line in the A-melding. Each change has its own mechanics and its own implications for cash flow and software configuration.

Change 1: skattetrekkskonto abolished. Until 31 December 2025, employers had to ring-fence withheld tax in a separate dedicated bank account — the skattetrekkskonto — or hold an equivalent bank guarantee. From 1 January 2026 that requirement is removed. Existing skattetrekkskonti are released back to the employer. For residual balances under NOK 12,000, the bank can auto-release the funds after 10 April 2026 without further documentation; larger residuals require the employer to actively close the account. For the foreign-employer reader, the practical effect is significant: opening a Norwegian skattetrekkskonto from abroad was historically one of the slowest steps in setting up Norwegian payroll, often involving in-person identification at a Norwegian bank branch. That requirement is gone.

Change 2: withholding paid directly to Skatteetaten the working day after salary. With the ring-fenced account gone, withheld forskuddstrekk no longer sits in a separate bank account waiting for the bi-monthly transfer. Instead, the withheld amount is transferred to the Norwegian Tax Administration's account the working day following the salary payment. According to Skatteetaten's tax deduction account guidance, from 1 January 2026 the requirement for withholding tax to be transferred to a tax deduction account is removed; employers must instead pay the withholding tax directly to the Norwegian Tax Administration. This is a cash-flow change as much as a reporting change. Cash that previously sat in the employer's skattetrekkskonto for up to six weeks between salary date and bi-monthly settlement now leaves the business within one banking day — finance teams running working-capital forecasts on Norwegian operations need to model the working-day-after-salary outflow rather than the 15th-of-even-month outflow they previously planned around.

An exception path exists. An employer that genuinely cannot pay the withholding the working day after salary — for example, a startup with a temporary liquidity issue or an employer awaiting a treasury transfer — can apply to Skatteetaten for a deferred-payment exemption. This is exception handling, not the standard regime, and the application is reviewed case by case.

Change 3: utbetalingsdato mandatory per wage line. Every wage line in the A-melding must now carry the actual payment date — utbetalingsdato — not just the period it relates to. Previously the field was optional or used inconsistently across vendors; from 1 January 2026 the receiver-side validation rejects A-meldinger without a populated utbetalingsdato on each line. The practical implication is that payroll software and any spreadsheet-based payroll register feeding into Altinn must populate the field on every line, including for back-payments processed in a later run, holiday pay paid out separately from the monthly cycle, and benefits-in-kind valued mid-period. A wage line for January salary paid on 25 January carries utbetalingsdato 25.01.2026; a back-payment for an October bonus issued in March carries utbetalingsdato 15.03.2026, even though the income period is October. The field tells Skatteetaten and NAV when the cash actually moved, which is what drives the working-day-after-salary skattetrekk transfer and the receiver-side benefit calculations.

Skattetrekkskonto abolished is not the same as the bi-monthly settlement

Several English-language summaries of the 2026 changes blur two distinct things. The skattetrekkskonto is a bank account: the requirement to hold withheld tax in a separate dedicated account between salary payment and settlement, abolished from 1 January 2026. The bi-monthly skattetrekk and AGA settlement is a payment cycle: the obligation to settle with Skatteetaten on the 15th of each even month (January, March, May, July, September, November), which remains a fixed feature of Norwegian employer obligations. Under the old regime they were related, because the bi-monthly transfer drew funds from the ring-fenced account, but they were never the same thing.

What changes from 2026 is what flows on that bi-monthly date. With the skattetrekk now transferred per pay run the working day after salary, the 15th-of-even-month payment is dominated by arbeidsgiveravgift for the termin (the two-month accounting period Norwegian payroll runs on), plus any small reconciliation of skattetrekk that did not transfer correctly. A finance team running Norwegian payroll from 2026 onwards therefore sees two streams of payment to Skatteetaten: the immediate skattetrekk transfer per wage run, and the bi-monthly AGA settlement covering each termin. The bi-monthly date itself is unchanged on the calendar; the cash mechanic behind it has moved.

Who is obliged to file, and where foreign employers fit

The trigger for an A-melding obligation is having anyone you pay for work performed in Norway, or anyone you pay as an employer with reporting obligations to Norway, regardless of where you are incorporated. The reportable payments cover salary, wages, holiday pay (feriepenger), sick pay, board fees, benefits-in-kind (naturalytelser), and certain reimbursements. Norwegian-incorporated employers — limited companies (AS), public limited companies (ASA), sole proprietorships (ENK), and general partnerships (ANS) — file an A-melding for every employment relationship, full stop.

Foreign employers are obliged in two main scenarios. The first is a foreign company with one or more Norwegian-resident employees working remotely from Norway — increasingly common as remote-first hiring has spread. The second is a foreign company seconding employees to Norway under a Norwegian-registered foreign enterprise structure. In both, the trigger is the same: the employee is tax-resident in Norway, and there is a payroll relationship, so the employer carries the A-melding obligation.

The PAYE (Pay As You Earn) scheme is a simplified flat-rate withholding regime designed for short-term foreign workers in Norway. It applies a flat 25% withholding rate, of which 7.7% is the national insurance contribution and 17.3% is income tax, and the worker has no obligation to file an annual Norwegian tax return. PAYE replaces the standard withholding-card process for eligible workers (typically those staying less than 183 days in any 12-month period and earning under the relevant income ceiling), and it has its own income type within the A-melding. The monthly filing obligation, however, is identical: the employer files an A-melding by the 5th of the following month for PAYE-scheme workers exactly as for standard-scheme workers.

Foreign citizens working as Norwegian-resident employees of Norwegian companies are covered by the standard A-melding mechanics. Citizenship does not change the employer's filing obligation; the obligation flows from the employment relationship and the employee's tax residence, not from passport details.

The Employer of Record (EOR) alternative deserves a clean treatment. A foreign company can engage a Norwegian-resident worker through an EOR provider that becomes the legal employer in Norway. In that case the EOR holds the Norwegian organisasjonsnummer, runs the Altinn account, and files the A-melding in its own name for the seconded worker. This is a commercial structuring choice, not a regulatory exemption from the A-melding regime — somewhere in the chain, an A-melding is being filed for that worker. The choice between EOR and direct filing is a question of whether the foreign company wants to hold its own Norwegian payroll capability or pay an intermediary to hold it for them. There is no scenario in which a paid Norwegian-resident worker is exempt from being reported.

For a foreign employer scoping its broader Norwegian compliance footprint, A-melding is one ongoing obligation among several. Other obligations relevant to the same finance team include MVA (Norwegian VAT) returns where the employer also has Norwegian sales, SAF-T reporting on demand from Skatteetaten, and the upcoming requirements under Norway's B2B e-invoicing mandate from 2027. Mapping the full compliance picture before going live with Norwegian operations saves repeated registration cycles.

Penalty exposure is concrete. Late or missing A-meldinger attract an administrative fine of NOK 131 per affected employee per day, capped at approximately NOK 1,314,000 per submission. For an employer with a hundred Norwegian employees, that accrues at NOK 13,100 per day until the A-melding is filed. The deadline matters operationally as well as regulatorily.

Registering as a foreign employer: NUF, D-nummer, and Altinn access

Before a foreign employer can file its first A-melding, four registrations need to be in place: the foreign enterprise itself in the Norwegian central register, an identifier for each employee, a Norwegian tax card per employee, and Altinn access for whoever will operate the submission. None of them are technically difficult, but they route through different agencies and need to be sequenced sensibly because each step depends on the prior one.

Step 1: register the foreign enterprise. A foreign company with operations or employees in Norway typically registers a Norwegian-registered foreign enterprise — norskregistrert utenlandsk foretak, abbreviated NUF — with the Brønnøysund Register Centre (Brønnøysundregistrene). The NUF is not a separate legal entity; it is the foreign company's registration in the Norwegian central register, identifying the same legal person under a Norwegian organisasjonsnummer (organisation number). Without an organisasjonsnummer, the employer simply cannot be identified as a filer in the A-melding system. Registration is online through the Brønnøysundregistrene portal and typically takes one to three weeks, depending on whether the foreign company's incorporation documents need apostilled translation.

Step 2: identifier for each employee. Every employee reported in the A-melding needs a Norwegian personal identifier. Norwegian-resident employees use their fødselsnummer — the 11-digit national identity number issued at birth or naturalisation. Non-resident employees, and resident employees who do not yet have a fødselsnummer, use a D-nummer: a temporary national identifier issued by the National Population Register, also 11 digits but with 4 added to the first digit of the date of birth (so a person born on the 5th of a month receives a D-nummer starting with 45 rather than 05). The D-nummer is requested by the employer through Skatteetaten as part of the tax card application for the employee, and it is generally issued within a few working days. Without a valid identifier per employee, the wage line will not validate in Altinn.

Step 3: tax cards. Each employee needs a Norwegian tax card (skattekort) so the correct forskuddstrekk rate applies. PAYE-scheme employees are flagged with the flat 25% rate (including the 7.7% national insurance share). Standard-scheme employees carry whatever percentage rate or tax-table number Skatteetaten has assigned based on their declared income and circumstances. Tax cards are pulled electronically from Skatteetaten by the payroll system or through Altinn — there is no paper card to handle, and the rates can change mid-year as the employee's circumstances change, so the payroll process needs to refresh the card before each run.

Step 4: Altinn access for the foreign business. Altinn is the Norwegian government's digital services portal, and an A-melding cannot be filed without it. Foreign employers access Altinn through one of two routes. The first is using a Norwegian electronic ID — BankID, MinID, Buypass, or Commfides — held by an authorised representative who has a Norwegian personal identity. The second is Altinn's foreign-business access route, which provisions credentials specifically for foreign-resident representatives without a Norwegian electronic ID. Whichever route is used, Altinn roles must then be assigned: the role required to submit A-meldinger (commonly Lønn og personalmedarbeider, the payroll and personnel officer role, or an equivalent delegated role) needs to be granted to the person or system that will file. Roles are assigned by the registered authorised representative under the organisasjonsnummer.

The EOR alternative collapses these four steps into a single commercial relationship. The EOR already holds an organisasjonsnummer, already operates Altinn under that number, and already has assigned roles. It registers the seconded employee as its own employee and files the A-melding in its own name. The trade-off is a per-employee monthly EOR fee against the time and ongoing operational cost of holding a Norwegian payroll capability directly. Neither choice is obviously right. Companies with one or two long-tenure Norwegian employees often go EOR because the four-step setup is disproportionate to the headcount; companies with a growing Norwegian team usually move to direct filing once the EOR fees outweigh the operational overhead and they want closer visibility into Norwegian payroll mechanics.

What each A-melding wage line carries

The A-melding consolidates everything a Norwegian employer reports about an employee in a given period into a single line, structured into several distinct blocks. A finance lead checking what their software, regnskapsfører, or EOR is filing on their behalf can use the block-by-block layout below to reconcile the wage register against what actually went to Skatteetaten, NAV, and SSB.

Arbeidsforhold (employment relationship). The employment context block carries the structural facts of the role: start date, employment type (ordinary employment, time-limited contract, freelance assignment, or board-fee position), occupation code (the yrkeskode drawn from SSB's STYRK-08 standard occupational classification), full-time or part-time status, contracted hours per week, percentage of full-time equivalence, and workplace location — specifically the kommune (municipality) in which the work is performed, since that determines the AGA zone. Changes to any of these — a promotion, an hours change, a transfer between offices, the end of the employment — are reported in the period the change takes effect, which means the arbeidsforhold block is not static across consecutive A-meldinger for the same employee.

Inntekt (income). The income block breaks the period's gross pay into income types, each with its own a-ordningen code so the receiver-side systems classify the payment correctly. Common income types include lønn (regular salary), overtidsgodtgjørelse (overtime), feriepenger (holiday pay), bonus, naturalytelser (benefits-in-kind such as company car, free phone, employer-funded insurance), and sluttvederlag (severance). The codes matter because NAV uses them when assessing eligibility for sickness benefits and unemployment benefits, and SSB uses them to compile national wage statistics. From 2026, every income line carries utbetalingsdato — the actual date the income was paid out — separate from the period the income relates to.

Forskuddstrekk (preliminary withholding). The withheld tax for the period, calculated from the employee's tax card. PAYE-scheme employees show the flat 25% withholding rate (including the 7.7% national insurance). Standard-scheme employees show the percentage rate or table-based withholding from their assigned skattekort. Under the 2026 regime, the same forskuddstrekk amount that appears on this line will already have been transferred to Skatteetaten the working day after the salary payment.

AGA-grunnlag, AGA-sats, beregnet AGA. Three fields that together describe the employer's national insurance contribution for the line. AGA-grunnlag is the base — typically the gross wage subject to AGA. AGA-sats is the rate, which varies by AGA zone. Norway uses a geographic-zone employer's national insurance system, with rates running from 0% in the highest-relief zones to 14.1% in zone 1 (the urban zone covering most large employers). The zone is determined by the employee's workplace municipality, not by where the employer is incorporated, which matters for an employer with employees spread across multiple Norwegian regions. Beregnet AGA is the calculated AGA amount — base multiplied by rate. The choice of zone for a particular employee, the rules around the differentiated AGA system, and the sectoral exemptions are a substantial topic in their own right; what matters at the wage-line level is that all three fields appear and are mutually consistent.

Permittering and fravær (lay-off and absence). Lay-off periods (permittering), sick leave (sykefravær), parental leave (foreldrepermisjon), and unpaid absences are reported with their start and end dates within the same A-melding line for the affected period. NAV uses these to administer benefit eligibility — sickness benefits, parental benefits, unemployment benefits — and SSB uses them in the labour-market statistics. Missing or mis-timed absence reporting often surfaces later as a NAV query, which is one of the more common practical reasons for filing a corrected A-melding.

The line-level structure is one of several Norwegian regulatory regimes that demand structured per-record data from the same finance team, alongside the on-demand requirements set out in Norway's SAF-T Financial audit-file requirements. The organisational benefit of investing in the per-line discipline is shared across both regimes: if the underlying ledger and master data are clean enough to produce a valid A-melding wage line, they are usually clean enough to produce a SAF-T export when Skatteetaten requests one.

Submitting through Altinn: RF-1373/A01 and software-mediated A02

A-meldinger reach Skatteetaten through Altinn, but there are two practical submission routes and the choice between them is a function of headcount and software setup rather than regulatory preference. Both routes produce the same kvittering and feed the same downstream reporting to Skatteetaten, NAV, and SSB.

Direct submission — RF-1373 (A01). The Altinn web form for the A-melding is RF-1373, also referenced as A01 in Skatteetaten's documentation. A user with the appropriate Altinn role (typically Lønn og personalmedarbeider) logs in to Altinn under the employer's organisasjonsnummer, selects the form for the relevant period, enters the wage lines per employee or imports from a structured XML file, validates the submission, and submits. The form enforces the receiver-side validations live — including, from 2026, the mandatory utbetalingsdato per line. RF-1373 fits employers with a small headcount and no integrated Norwegian payroll software: a NUF with two or three employees can run a clean monthly cycle directly through the Altinn web form, especially if the wage data already lives in a spreadsheet that can be imported.

System-mediated submission — A02. Payroll software submits the A-melding programmatically through Altinn's A02 channel using the employer's API credentials. Most Norwegian payroll vendors — Visma Lønn, Tripletex, PowerOffice GO, Sticos Lønn, Conta — handle the A-melding submission as part of the monthly payroll close. The software calculates wages, withholding, and AGA from the employee master and the period's transactions, packages the A-melding payload (the same data structure as the A01 form, just transmitted as XML over the API), and submits it through A02. The kvittering returns to the software and is also visible in Altinn under the employer's organisasjonsnummer for any user with appropriate roles. For employers above a handful of employees, A02 is the practical default; the alternative is re-keying every wage line into the web form each month.

For foreign employers without a Norwegian payroll system, two common patterns dominate. The first is engaging an external regnskapsfører — an accountant authorised to act on a client's behalf under Regnskapsførerloven (the Accounting Profession Act) — who holds the foreign employer as a client, runs payroll through its own Norwegian software, and submits the A-melding on the employer's behalf. The second is the EOR route, where the EOR holds the employer relationship and files in its own organisasjonsnummer rather than the foreign company's. Direct A01 submission from abroad is technically possible — it just requires Altinn's foreign-business access route described in the registration section — but it is operationally rare beyond very small headcounts because the manual data entry consumes more time than the regnskapsfører fee saves.

The submission window and validation behaviour. A-meldinger for a given month can be submitted from the start of the following month through to the 5th of that following month — so a January A-melding can be submitted any time between 1 February and 5 February. Late submissions are accepted, but the per-employee-per-day administrative penalty noted earlier accrues from the day after the deadline until the A-melding is filed. Validation rejections — missing identifiers, invalid AGA codes, inconsistent income totals, missing utbetalingsdato — must be corrected and the A-melding resubmitted before it counts as filed. A validation rejection on the 5th does not buy an extra day; the clock keeps running.

Multiple submissions per period are allowed and expected. An employer can file an A-melding for a period and then file additional A-meldinger for the same period to add wage lines, amend previously submitted lines, or correct errors. The receiver-side system aggregates the latest valid version of each line — there is no separate "amendment form". The kvittering for the latest submission shows the merged result. This is the same mechanic the corrections workflow uses; the difference is whether the additional submission lands inside the original 5th-of-month window (in which case it is a within-period adjustment) or after it (in which case it is a correction with the timing implications covered in the closing section).

The kvittering: what it contains, why it matters, and extracting it to Excel

After every A-melding submission, Altinn returns a kvittering — a structured submission receipt. The kvittering carries the submission ID, the period (month and year), the employer name and organisasjonsnummer, the count of wage lines submitted, the totals for gross wages, forskuddstrekk, and AGA, any error or warning codes returned by the receiver-side validation, and the submission timestamp. It is downloadable as a PDF and remains accessible in Altinn under the employer's account for the statutory retention period. Every A-melding submission produces a kvittering, including each successive submission for a given period when corrections are filed.

Operationally the kvittering is the document that matters. Auditors treat it as the primary evidence that the A-melding was filed for the period. AP teams reconcile the totals on the kvittering against the payroll register and against the bank settlement of the bi-monthly skattetrekk and AGA payment. Internal controls frameworks at multinationals typically require the kvittering for each month's payroll to be retrievable from the records system on demand for the statutory retention period under Bokføringsloven. A foreign-resident finance team that does not log into Altinn directly relies on the kvittering as the canonical confirmation that its Norwegian operations are filed.

The lønnsslipp (payslip) is the per-employee equivalent record. Each pay run produces one lønnsslipp per employee, showing the gross income, withholding, deductions, and net pay for that employee for that period. Together, the employer's monthly kvittering and the per-employee lønnsslipper form the payroll-document set that month-end close, audit, and HR reconciliation typically need.

The extraction problem follows. Multinational finance teams need kvitteringer and lønnsslipper from multiple Norwegian payroll cycles consolidated into a spreadsheet for cost-centre allocation, head-office reconciliation, audit packs, or HR analytics. The artefacts are PDFs; the destination is Excel. A practical complication is that lønnsslipper are not standardised across Norwegian payroll vendors — Visma, Tripletex, PowerOffice GO, Conta, and Sticos each issue payslips with a different layout, different field labels, and different combinations of Norwegian and English labelling. A finance team consolidating documents from a mixed vendor portfolio cannot rely on a single template. This is where prompt-based extraction tools fit: a team can extract A-melding kvitteringer and lønnsslipper to Excel by uploading the PDF set and prompting for the fields they need, with the same prompt working across vendor layouts because it describes what to extract rather than where on the page each field sits. The general principles for automating payroll PDF extraction into Excel apply equally across other countries' payroll documents.

The bi-monthly skattetrekk and AGA settlement cycle

The bi-monthly termin runs in pairs of months. Termin 1 covers January and February, settled on 15 March. Termin 2 covers March and April, settled on 15 May. Termin 3 covers May and June, settled on 15 July. Termin 4 covers July and August, settled on 15 September. Termin 5 covers September and October, settled on 15 November. Termin 6 covers November and December, settled on 15 January of the following year. The settlement always falls on the 15th of the month following each two-month period — so on the 15th of every even month, plus 15 January for termin 6.

What is settled on the 15th, from 2026 onwards, is principally arbeidsgiveravgift for the two-month period plus any reconciliation of skattetrekk that did not transfer correctly under the working-day-after-salary mechanic — typically a small balancing amount rather than the full skattetrekk for the period. Because the skattetrekk is now transferred per pay run, the 15th-of-even-month payment is dominated by the AGA component. For an employer with stable monthly payroll, the bi-monthly payment is essentially the AGA accrual for the two months covered.

Each bi-monthly settlement produces a Skatteetaten payment receipt. The payment is initiated against a kid number (the Norwegian customer identification number that ties a payment to the specific tax obligation it settles) using the OCR-linje on the payment slip Skatteetaten issues. The bank confirmation of the transfer, plus Skatteetaten's matching receipt, becomes the cash-side evidence reconciled against the GL accrual for the termin. The kvitteringer for the underlying A-meldinger remain the per-month evidence on the reporting side; the bi-monthly settlement receipt is the evidence on the cash side. Both flow into the audit pack.

The bi-monthly payment is initiated by the employer (or the payroll vendor or regnskapsfører acting for them); Skatteetaten does not direct-debit. The workflow runs through the employer's Norwegian bank, so a foreign treasury team needs cleared funds in the Norwegian operating account by the 14th to settle on the 15th. Missing the 15th attracts late-payment interest under the standard Norwegian tax-payment regime, accruing daily from the original due date. That penalty mechanic is separate from the late-A-melding administrative fine covered earlier; they are different infractions and can both apply if both are missed.

Treasury and AP teams updating their Norwegian-payroll SOPs in 2026 should rewrite the cash-flow diagrams rather than just changing the dates. Under the old regime the 15th moved both AGA and accumulated skattetrekk; from 2026 only AGA and any reconciliation moves on that date.

Corrections, the simplified scheme, and the monthly calendar to put on the wall

Corrections. A-meldinger are corrected by submitting a corrected version of the relevant period rather than by issuing a separate amendment form. The mechanic is straightforward: file an additional A-melding for the same period, with the corrected wage lines, through the same A01 web form or A02 system channel that filed the original. The receiver-side system uses the latest valid version of each line; earlier versions remain in the audit trail but the operative numbers come from the most recent submission. Corrections submitted before the 5th of the following month do not attract penalty interest because they land within the original filing window. Corrections submitted after the deadline are still accepted, but interest accrues from the original deadline on any underpaid skattetrekk or AGA the correction surfaces. Common correction triggers in practice: a bonus or back-payment missed in the original run, an incorrect tax-card rate applied because the card was not refreshed before payroll, an AGA zone error after an employee changed workplace municipality, a benefit-in-kind valuation update following a year-end review, an end-of-employment date entered incorrectly when an employee left mid-period.

Forenklet A-melding for household employment. Households that employ someone for cleaning, childcare, gardening, or similar work performed in a private home file the simplified A-melding — forenklet A-melding — under a separate scheme designed for the small-scale private-household case. Below NOK 6,000 paid per worker per calendar year, the household has no filing obligation at all. Above NOK 6,000, the simplified scheme applies, using a fixed-rate withholding and a streamlined Altinn submission flow specific to private households. This is a different regulatory track from the standard A-melding the rest of this article covers. It does not apply to commercial employers regardless of size, and a foreign employer engaging Norwegian-resident workers for commercial purposes is in the standard regime no matter how few employees are involved.

The monthly cycle as a calendar. A payroll team running Norwegian operations from 2026 onwards can keep the cycle on the wall as four checkpoints:

Within the month. Wages paid on the employer's chosen pay date. Forskuddstrekk transferred to Skatteetaten the working day after each salary run. Utbetalingsdato recorded on every wage line in the payroll system — back-payments, holiday pay, and benefits-in-kind all carry their own utbetalingsdato.
By the 5th of the following month. A-melding submitted through Altinn (RF-1373/A01 directly, or A02 from the payroll system). Kvittering received, reviewed for warning codes, and filed with the period's payroll records. Any within-window adjustments resubmitted before the 5th to avoid the late-filing penalty.
On the 15th of each even month, plus 15 January. Bi-monthly AGA settlement to Skatteetaten covering the prior two-month termin, paid against the kid number and OCR-linje on the Skatteetaten payment slip. Bank confirmation reconciled against the GL accrual for the termin.
Ad hoc. Corrections filed as additional A-meldinger for the affected period, with interest accruing if the correction lands after the original 5th-of-month deadline.
