A VAT apportionment scheme 1 example for a UK convenience store starts with one rule: use the VAT-rate mix of goods bought for resale to estimate the VAT-rate mix of Daily Gross Takings. According to HMRC's Apportionment VAT Retail Schemes notice, Apportionment Scheme 1 is for businesses with annual tax-exclusive retail turnover not exceeding GBP 1 million, and it works by applying the VAT-rate proportions of purchases for retail sale to daily gross takings. Once gross takings have been split that way, the standard-rated portion is converted to VAT by taking one sixth, the reduced-rated portion by taking one twenty-first, and the zero-rated portion creates no output tax.
That makes the scheme useful for the typical mixed-rate convenience store. A corner shop may sell bread, milk, canned food, beer, spirits, tobacco, confectionery, soft drinks, and a few household lines, but the till report does not always produce a dependable sales split by VAT rate. Apportionment Scheme 1 gives the shop another route: build the proportions from purchase invoices, then apply them to the shop's Daily Gross Takings.
The arithmetic always follows the same shape:
- Total the eligible purchases for retail resale for the period, grouped by VAT rate.
- Calculate each rate's percentage of total eligible purchases.
- Apply those percentages to the same period's Daily Gross Takings.
- Take one sixth of the standard-rated takings and one twenty-first of the reduced-rated takings.
- Leave the zero-rated portion in the sales split, but with no output tax attached to it.
The worked example in this article uses a realistic week of convenience-store buying, mixed wholesaler invoices, an alcohol delivery, tobacco stock, and one genuine reduced-rate line. That matters because most ranking pages stop at the formula. The practical question is not whether the formula exists. It is whether a bookkeeper can take a real pile of purchase documents, classify them properly, match them to the same week's takings, and arrive at a defensible VAT figure.
Which Purchases Go Into the Scheme, and Which Stay Out
For Apportionment Scheme 1, the purchase side is not "everything bought this week". It is goods bought for retail sale, grouped by VAT liability, for the same period as the takings being apportioned. In a convenience store that usually means building three buckets from supplier documents: zero-rated resale stock, standard-rated resale stock, and reduced-rated resale stock if the shop genuinely carries any.
A realistic purchase pile might include Booker or Bestway lines for bread, milk, tinned food, rice, and other staple groceries that are zero-rated. The same pile may also include standard-rated beer, wine, spirits, tobacco, confectionery, soft drinks, disposable vapes where applicable, and small household sundries. If the weekly paperwork includes mixed cash-and-carry documents, how to book Booker and Bestway invoices for a UK convenience store sits naturally alongside the VAT-coding work. If alcohol stock is coming from multiple suppliers, checking each wholesaler's AWRS URN belongs alongside the VAT coding work. Some shops also sell smokeless coal or another genuine domestic-fuel line, which can create a reduced-rated bucket. The scheme works because those buckets describe the VAT character of stock bought for resale, not because they mirror suppliers one for one.
What stays outside the scheme matters just as much. Services do not belong in the apportionment pool. Nor do catering sales, goods made or grown by the retailer, or stock bought for non-retail or B2B activity. If the shop has a separate wholesale side-line, a bill for cleaning, card terminal charges, or packaging that is not itself retail stock, those amounts should not be pushed into the purchase totals just to make the spreadsheet tie. Personal-use adjustments and similar distortions are dealt with separately, not buried inside the main rate split.
This is also where people blur purchase-side evidence with sales-side evidence. Purchase invoices establish the proportions. Daily Gross Takings establish the gross sales value to which those proportions are applied. One does not replace the other. If the invoices are classified correctly but the DGT period is wrong, the result is wrong. If the DGT is right but standard-rated and zero-rated purchases have been mixed together, the result is still wrong.
For that reason, the document-handling step is load-bearing. A bookkeeper needs enough line detail to sort stock into the correct VAT-rate bucket, retain the working paper, and explain later why each figure was included. If the source documents themselves are unclear on tax treatment or invoice basics, the starting point is still UK VAT invoice requirements. If the weekly buying comes from several wholesalers and delivery notes need turning into a clean VAT-coded working file, the broader grocery invoice processing workflow is the operational companion. Apportionment Scheme 1 is not difficult because the formula is complex. It is difficult because a mixed-rate retail week only becomes usable once the purchase evidence has been classified cleanly.
A Worked Example From Weekly Purchases to VAT Due
Here is the part most readers actually need: the full sum. Assume the shop is using Apportionment Scheme 1 for one VAT week and has already separated eligible resale purchases from everything that sits outside the scheme. The purchase file for that week contains a Booker statement, a Bestway top-up, an alcohol delivery, tobacco stock, confectionery and soft drinks, plus one reduced-rate domestic-fuel line.
The eligible ex-VAT purchases look like this:
| VAT rate | Example stock in the bucket | Eligible purchases |
|---|---|---|
| Zero-rated | Bread, milk, canned food, rice, staple groceries | GBP 4,910.40 |
| Standard-rated | Alcohol, tobacco, confectionery, soft drinks, household sundries | GBP 3,218.75 |
| Reduced-rated | Smokeless coal | GBP 426.85 |
| Total | All eligible goods bought for retail resale | GBP 8,556.00 |
That gives the following purchase proportions:
| VAT rate | Calculation | Purchase share |
|---|---|---|
| Zero-rated | 4,910.40 / 8,556.00 | 57.3913% |
| Standard-rated | 3,218.75 / 8,556.00 | 37.6198% |
| Reduced-rated | 426.85 / 8,556.00 | 4.9889% |
Assume the same week's Daily Gross Takings total GBP 13,742.60. Under Apportionment Scheme 1, those purchase proportions are applied to DGT to estimate the VAT mix of sales:
| VAT rate | Apportionment step | Apportioned gross takings |
|---|---|---|
| Zero-rated | 57.3913% x 13,742.60 | GBP 7,887.06 |
| Standard-rated | 37.6198% x 13,742.60 | GBP 5,169.94 |
| Reduced-rated | 4.9889% x 13,742.60 | GBP 685.60 |
| Total | Estimated split of weekly DGT | GBP 13,742.60 |
Now convert only the positive-rated portions into output tax:
| VAT rate | VAT fraction | VAT due |
|---|---|---|
| Standard-rated | 5,169.94 / 6 | GBP 861.66 |
| Reduced-rated | 685.60 / 21 | GBP 32.65 |
| Total output tax from the scheme | Standard-rated VAT + reduced-rated VAT | GBP 894.31 |
That is the complete working. The zero-rated share still matters because it is part of the gross-sales split, but it contributes no output tax. The standard-rated and reduced-rated shares matter twice: first in allocating takings, then in turning the gross allocated amounts into VAT using the correct fractions.
If you prefer the formula without the table, it is this:
- Purchase proportion at each VAT rate = purchases at that rate / total eligible purchases
- Gross takings at each VAT rate = purchase proportion x Daily Gross Takings
- Output tax = standard-rated gross takings / 6 + reduced-rated gross takings / 21
This is why a strong HMRC Notice 727/4 worked example is so useful. The formula itself is short, but the operational discipline sits underneath it. The bookkeeper has to make sure the purchases are genuinely eligible for resale, the DGT covers the same period, and the reduced-rate bucket only exists if the shop actually sells reduced-rate stock. If the shop carries no genuine reduced-rate lines, the method does not change. That column simply drops to nil, and the one-twenty-first step disappears.
Daily Gross Takings, Annual Adjustment, and MTD Record-Keeping
Daily Gross Takings are the sales-side input to the scheme. In practice that means the shop needs a dependable daily takings record, usually from Z-reads, till rolls, or the equivalent daily close-out report, covering the same period as the purchase mix. Apportionment Scheme 1 does not remove the need for sales evidence. It changes how the VAT split is estimated when the till cannot produce that split directly.
The record trail usually has three layers. First, the purchase records show what stock was bought for retail resale and how it was classified by VAT rate. Second, the daily takings records show the gross value of sales for the same period. Third, the working paper joins the two, showing the percentage split, the apportioned takings, and the VAT fractions used. If any one of those layers is missing, the final VAT number becomes much harder to defend.
That working paper also matters because Apportionment Scheme 1 is not just a weekly shortcut. A shop should expect to review the calculation across the year and make the annual adjustment required by the scheme so the final VAT position reflects the trading pattern over the full period, not just a series of isolated week-by-week estimates. In practice that means doing a similar calculation for the whole year's sales and purchases, then correcting any overpayment or underpayment that built up during the year. A convenience store with a strong Christmas alcohol swing, a seasonal fuel line, or a changing mix between groceries and impulse items can drift materially if the annual check is ignored.
MTD for VAT sits underneath this as compliance plumbing. The point is not to turn a retail-scheme article into a general MTD explainer. The practical point is that the purchase data, the takings records, and the apportionment working should move through the record-keeping chain with digital links intact. Re-keying figures from one spreadsheet or system into another is exactly the sort of breakpoint that creates avoidable compliance risk. The same logic that makes paperless invoice processing useful for invoice handling also matters here: cleaner source data makes the VAT working easier to support.
For a bookkeeper, the useful habit is simple. Build the purchase buckets from the week's source documents, tie them to the same period's DGT, save the apportionment working, and keep enough detail that the annual adjustment can be reconstructed later. The scheme is an estimation method in one sense only: the sales split is estimated. The evidence trail should not be.
When Apportionment Scheme 1 Is the Right Fit, and When It Is Not
The real decision is not whether Apportionment Scheme 1 exists. It is whether it is the best fit for the shop in front of you. For a mixed-rate convenience store under the turnover ceiling, the scheme is usually strongest where the shop sells a meaningful volume of zero-rated groceries alongside standard-rated lines, but the till system cannot produce a reliable VAT-rate sales analysis.
That is the practical heart of the apportionment scheme 1 vs point of sale scheme question. Point of Sale Scheme is usually better where the EPOS setup genuinely captures the VAT rate of each sale and the resulting reports are dependable enough to support the return. In that situation there is less reason to estimate from purchases because the till is already telling the business what it sold by rate.
Apportionment Scheme 1 becomes attractive where the shop's stock mix is genuinely mixed but the sales-side reporting is blunt. Many independent stores can produce a daily takings total, yet not a clean split between zero-rated food and standard-rated impulse lines. That is exactly the gap Apportionment Scheme 1 fills. It uses purchase evidence that the business already has to build a defensible estimate of the sales mix.
Direct Calculation can be better in a narrower set of cases. If only a small minority of stock is standard-rated, and the positive-rated sales can be identified more directly than a full apportionment would allow, Direct Calculation may produce a cleaner result with less distortion. The same applies if the shop's trade is unusual enough that purchase mix is a weak proxy for sales mix. A convenience store with a limited grocery offer but a heavy alcohol and tobacco bias may find the standard worked example in this article far less representative than a classic mixed-food corner shop.
The comparison is easier to hold in one place:
| Scheme | Best fit | Weak fit |
|---|---|---|
| Apportionment Scheme 1 | Mixed-rate convenience store, turnover within limit, weak VAT-rate reporting from the till | Off-licence-heavy or otherwise unusual mix where purchases are a poor proxy for sales |
| Point of Sale Scheme | EPOS can reliably report sales by VAT rate | Till cannot support a dependable rate split |
| Direct Calculation | Only a small share of sales is positive-rated and can be isolated directly | Typical convenience-store mix where zero-rated and standard-rated lines both matter materially |
So when is it the right answer for a VAT retail scheme small shop? Usually when the business is still small enough to qualify, the stock mix is broad enough that zero-rated and standard-rated sales both matter, and the till system is not sophisticated enough to justify Point of Sale Scheme. Once annual tax-exclusive retail turnover moves beyond the GBP 1 million ceiling for Scheme 1, the business should plan for a different route, often Apportionment Scheme 2 or another method that better matches the size and reporting capability of the shop. When those conditions stop being true, the scheme should be reviewed rather than defended out of habit.
Common Edge Cases That Distort the Calculation
Most bad results do not come from the formula. They come from unexamined edge cases. If stock is taken for personal use, consumed by staff, written off, donated, or diverted into a non-retail side-line, the purchase mix can stop reflecting the sales mix that the scheme is supposed to estimate. The spreadsheet may still calculate cleanly, but the answer underneath it is weaker.
Promotions create a similar problem in a different way. A heavy discount on standard-rated beer may change the value of sales faster than the purchase mix changes, especially if the promotion is short and the purchase stock was built earlier. The same issue appears if a shop buys heavily at the end of one VAT period but sells the stock in the next. Period matching matters. Apportionment Scheme 1 works best when the purchase mix used in the working paper is a fair proxy for the takings period being apportioned.
It is also easy to overstate what belongs in the scheme. A separate wholesale delivery run, a catering counter, or any non-retail activity can distort a corner shop VAT return calculation if those figures are pushed into the main apportionment pool. The method is a practical estimation tool for retail takings. It is not a licence to mix unrelated activity into one percentage split because it is convenient.
This is why many firms end up maintaining an apportionment scheme 1 spreadsheet with an adjustments section rather than a single bare formula. The spreadsheet is not there to make the maths look impressive. It is there to show which purchases were eligible, which were excluded, what adjustments were made, and why the chosen period still makes sense.
In live bookkeeping, the safest next move is usually to rebuild the working paper from eligible purchases and the same period's Daily Gross Takings, then sanity-check whether the current stock profile still fits the scheme. If the business has shifted toward alcohol, added wholesale activity, or crossed the turnover limit, the right response is to review the method, not to keep rolling last quarter's percentages forward unchanged.
