Input Tax Apportionment in the UAE: Recovering VAT on Mixed Supplies

Most VAT-registered businesses in the UAE never have to think about input tax apportionment, and that is exactly why the ones that do are so often caught out. If everything you sell is taxable, recovering the 5% you pay on your costs is a straightforward offset. The picture changes the moment part of what you supply is exempt. Then the tax you pay on your purchases stops being fully reclaimable, and you have to answer a harder question for every cost you incur: how much of this VAT actually relates to the part of the business that gives me the right to recover?

That question is what apportionment answers. It is not an obscure edge case — it reaches any business that mixes standard-rated or zero-rated activity with exempt income, from a trading company with a sideline in financial services to a property developer holding both commercial and residential units. Get the method right and consistent, and it becomes a quiet monthly routine. Get it wrong, or ignore it until year-end, and it becomes one of the more awkward items an FTA reviewer can raise. This guide explains when apportionment applies, how the standard method works, why the annual wash-up matters, and when a special method is worth the effort. For a cost category that raises the same recover-or-not question at a more granular level, see our VAT on staff expenses in the UAE guide.

Why apportionment exists at all

The whole logic of VAT recovery rests on one principle: you recover input tax to the extent your costs support the making of taxable supplies. You charge output VAT on your taxable sales, and in return you reclaim the input VAT on the purchases that went into making them. The system nets off across the chain, and the final consumer bears the tax.

Exempt supplies sit outside that deal. When you make an exempt supply — certain financial services, the supply of residential property after its first sale or lease, bare land, or local passenger transport — you do not charge output VAT, and correspondingly you do not recover the input VAT on the costs that produced it. The exemption is not a benefit; it removes that activity from the recovery mechanism. Once you see the difference, apportionment follows naturally, and our guide on zero-rated versus exempt supplies in the UAE is worth reading alongside this one, because the two are easy to confuse and only one blocks recovery.

So a business that does both — taxable and exempt — cannot recover all of its input VAT and must not recover none of it. It has to find the line in between. Apportionment is the mechanism the UAE VAT legislation gives you to find that line in a way the FTA will accept.

If you want the apportionment definition in a single line, it is the pro rata split of input VAT between the part of a business that carries a right of recovery and the part that does not. Anyone with a cost-accounting background will recognise the mechanic immediately, because it is the same pro rata basis used to spread an overhead cost across departments — only here it is spreading recoverable tax across activities, and the FTA rather than management decides which basis is acceptable. VAT exemption in the UAE is deliberately narrow, so most businesses never meet this at all; the ones that do usually meet it through property or financial income.

The three-bucket approach

Before any percentage is calculated, apportionment is a sorting exercise. Every dirham of input tax you incur has to land in one of three buckets, and the sorting is done first because it decides how much even needs apportioning.

The first bucket is input tax that is wholly attributable to taxable supplies. The stock a trader buys to resell, the direct costs of a standard-rated service, the materials that go into a commercial building — the VAT on all of it is recoverable in full, because those costs support only taxable activity. Nothing about being partly exempt changes recovery on genuinely taxable-only costs.

The second bucket is input tax that is wholly attributable to exempt supplies. Costs incurred solely to make exempt income — for example, expenses tied only to exempt financial services or only to residential lettings — carry input VAT that is simply not recoverable. It is blocked, in the same practical sense as the entertainment and personal-use motor vehicle blocks that catch out businesses even when they are fully taxable. If you want the fuller picture on what qualifies and what is blocked, our note on input VAT recovery in the UAE covers the ground.

The third bucket is the one apportionment is really about: residual input tax. These are the shared overheads that support the business as a whole and cannot honestly be pinned to either side — office rent, utilities, accounting software, audit fees, general marketing. The VAT on all of it relates to taxable and exempt activity at once, and this residual pot is what the apportionment percentage is applied to. What makes the whole thing work is doing the sorting at the point of posting rather than at year-end, so the three buckets exist in your ledger as routine, not reconstruction.

The standard method: an input-based ratio

The default method every partly exempt UAE business starts with is the standard method, and it is worth understanding precisely because it is not what most people first assume. It is not based on the value of your sales. It is based on your input tax.

Here is how it runs. First, you recover in full the input tax in bucket one. Second, you recover nothing from bucket two. Third, for the residual input tax in bucket three, you apply a recovery percentage. That percentage is the input tax that was directly attributable to taxable supplies, expressed as a proportion of the total input tax that was directly attributable to either taxable or exempt supplies — in other words, bucket one divided by bucket one plus bucket two. The result is rounded to the nearest whole number and applied to the residual pot.

To picture it: if your directly attributable costs show that roughly seventy per cent of your traceable input tax supported taxable activity, the standard method lets you recover seventy per cent of the residual overhead VAT too, on the reasoning that your overheads split much like your direct costs. It is a proxy for how the shared costs are used — but a defensible, consistent one.

Because the percentage is worked out for each tax period, it moves around. A period heavy with taxable-related costs produces a higher recovery rate; a quiet period skewed towards exempt activity produces a lower one. That volatility is expected, and it is precisely why the method does not stop at the periodic calculation.

Your tax year is not necessarily your financial year

Before the wash-up can mean anything, you have to know which twelve months it covers — and this is the step that quietly derails more apportionment calculations than the percentage itself. The tax year for apportionment purposes is defined in Article 55 of the Executive Regulation, Cabinet Decision No. 52 of 2017 as amended by Cabinet Decision No. 100 of 2024. It is tied to your VAT filing stagger, not to your accounting year end.

The consequence is concrete. A Dubai company with a 31 December accounting year end that files VAT quarterly on the February stagger has a tax year ending on the last day of February. Its wash-up covers March to February, not January to December, and the adjustment goes into the March–May return. Running the calculation on the calendar year instead produces a number that reconciles to nothing.

Article 55(12) adds a proportionality rule that matters in the same breath. Where a tax year is shorter than twelve months — because you deregistered part way through, or joined a group — the AED 250,000 actual-use threshold is scaled down in proportion to the length of that shortened period. A six-month tax year carries a AED 125,000 threshold, not the full figure.

The annual wash-up

Period-by-period percentages are a reasonable running estimate, but they rarely add up to a fair figure for the year as a whole. Timing distorts them. A large one-off overhead landing in a single period, a seasonal swing in exempt income, an annual insurance renewal — any of these can push a period’s recovery rate away from what the full year justifies. Left uncorrected, you would either have recovered more input tax than the year supports, or less.

The wash-up fixes this. At the end of your tax year you recalculate the recovery percentage using the figures for the entire year, apply that single annual rate to the year’s total residual input tax, and compare the answer with the sum of what you actually recovered across your periodic returns. If the two differ, you make an adjustment: repay the excess if you over-recovered, or claim the shortfall if you under-recovered. That adjustment is reported in the first tax period following the end of the tax year, and it becomes part of that return.

“

The periodic apportionment percentage is an estimate; the annual wash-up is the settlement. Businesses that skip the wash-up are not simplifying their VAT — they are leaving an unreconciled position on the record for a reviewer to find.

There is a further point that partly exempt businesses need on their radar. Where the actual use of goods and services over the tax year differs from the standard-method result by more than a set amount of VAT — the legislation sets that figure at AED 250,000 in a tax year — the business is required to make an adjustment reflecting actual use in the first period after the year. In plain terms, if the standard method has produced a recovery figure that is materially out of step with how the costs were genuinely used, you cannot simply bank the difference. This is the mechanism that stops the standard proxy from delivering an unfair result on a large scale, and it is one of the triggers that pushes bigger or more complex businesses towards a special method.

A worked year: AED figures through four quarters and the wash-up

The mechanics are easier to trust once you have watched them run. Take a Dubai property company on the 31 March quarterly stagger, so its tax year runs 1 April to 31 March. It lets commercial units (taxable at 5%) and residential units (exempt after the first supply), and carries the usual shared overheads — head office rent, audit fees, accounting software, general marketing.

Illustrative worked example prepared by Velmont Crest. The percentages follow the Article 55(7) method: bucket 1 divided by bucket 1 plus bucket 2, rounded to the nearest whole number.

Now run the wash-up required by Article 55(9) and 55(10). The annual recovery percentage on the full-year figures is 300,000 divided by 460,000, which is 65.2%, rounding to 65%. Applied to the year’s residual pot of AED 164,000, that gives AED 106,600 of properly recoverable residual input tax. The company actually recovered AED 106,760 across its four returns. It over-recovered by AED 160, and repays that difference in the Apr–Jun 2027 return — the first tax period of the following tax year.

Notice how small the wash-up came out even though the quarterly percentages swung from 45% to 80%. That is the ordinary case, and it is why the wash-up is a control rather than a windfall. The number only becomes material when the periodic mix is genuinely unrepresentative — a year with one enormous exempt-side cost in a single quarter, say — and that is exactly the situation Article 55(11) is built to catch.

Capital assets are monitored separately, over five or ten years

The annual wash-up settles the year. It does not settle a building. Large items of expenditure are pulled out of the ordinary apportionment cycle and tracked under the Capital Assets Scheme in Articles 57 and 58 of the Executive Regulation, on a much longer horizon.

Source: Cabinet Decision No. 52 of 2017, Articles 57 and 58, Article 58 as amended by Cabinet Decision No. 100 of 2024. Text read 4 August 2026.

The adjustment itself is arithmetic rather than judgement. Article 58 asks you to record the input tax incurred in Year 1 (W) and the percentage that gave rise to the Year 1 recovery (X) in a capital asset register. Each later year you compute that year’s percentage (Q), then compare one tenth of W times Q against one tenth of W times X for a building — one fifth for anything else. If the first is larger you increase your input tax by the difference; if it is smaller you reduce it. There is no rounding of the outcome and no discretion in it.

For a partly exempt property business this is the provision with the most money attached. A commercial building bought for AED 40,000,000 carries AED 2,000,000 of input tax, and a ten-point drift in the recovery percentage across a single year moves AED 20,000 in that year’s return. Over a ten-year monitoring period, on a portfolio, the cumulative effect dwarfs anything the ordinary wash-up produces. Article 58(4) requires the capital asset register in its own right, so this is not a calculation you can reconstruct later from the general ledger.

Worth saying plainly, though: the AED 5,000,000 entry point means most UAE SMEs never touch this scheme at all. A Dubai consultancy or a Sharjah trading company fitting out an office for AED 600,000 is nowhere near it, and neither is a small Abu Dhabi landlord. The businesses that do cross it are property developers, hotel owners, manufacturers buying plant, and free zone operators building their own premises — and for them the staged-payment aggregation in Article 57(3) is the trap, because no single invoice ever reaches AED 5,000,000 while the project as a whole comfortably does.

Special methods: when the standard one is not fair

The standard method is a blunt instrument by design — one simple ratio applied to every business. For many partly exempt SMEs it is perfectly adequate. For some businesses, though, the input-based ratio produces a recovery figure that does not reflect how the operation actually works, and for those the FTA allows a special method.

You cannot simply choose one. A special method has to be applied for and approved. Broadly, a business needs to have been registered for VAT for at least six months, to be making both taxable and exempt supplies, and to be able to demonstrate that the standard method does not give a fair and reasonable result. The application goes to the FTA, and until approval is granted the standard method continues to apply. Approvals are not open-ended either — they are typically granted for a defined term, with sectoral methods reviewed on a shorter cycle than non-sectoral ones.

The FTA has set out recognised special methods aimed at particular sectors:

• Outputs-based method — recovery driven by the value of taxable versus total supplies, made available to sectors such as insurance, retail and wholesale banking, and local transport providers, where an outputs measure better tracks real use than input tax does.
• Transaction count method — recovery based on the number of taxable versus total transactions, aimed at banks engaged in wholesale and investment trading, where transaction volume is the meaningful driver.
• Floor space method — recovery based on the area used for taxable versus exempt activity, which fits the real estate sector where a building is split between commercial (taxable) and residential (exempt) use. If property is your world, our overview of VAT on real estate in the UAE sets out where the taxable and exempt lines fall.
• Sectoral method — for large, complex businesses running genuinely distinct divisions with separate operational and accounting identities, allowing each sector to apportion in the way that suits it before the results are combined.

The Executive Regulation adds three procedural rules around all of this that are worth knowing before you apply. Article 55(13) is the gateway: where the standard calculation gives a result the taxable person considers does not reflect the actual extent to which input tax relates to making taxable supplies, they may apply to the FTA to authorise an alternative basis from the Authority’s list of accepted mechanisms — and the same clause lets the FTA compel an application. Article 55(14) allows approval from a future date on the Authority’s conditions. Article 55(15) then locks you in: you may only apply to change an alternative mechanism after at least two tax years from the approval to use it.

There is also a lighter option that businesses overlook. Article 55(16) lets you apply to use a specified recovery percentage based on the preceding tax year’s percentage, applied in each tax period, without prejudice to the wash-up and actual-use provisions. For a business with a stable activity mix, that removes the quarterly recalculation entirely while leaving the annual settlement intact — a smaller ask than a full special method, and a much shorter conversation with the Authority.

The theme across all of them is the same: match the recovery basis to the economic reality of the business. A special method is more work to set up and maintain, and it commits you to the FTA-approved basis for its term, so it earns its place only when the standard method genuinely misstates recovery. For most SMEs it will not — but for those in the named sectors, or those tripping the actual-use adjustment year after year, it is the right conversation to have.

Where apportionment goes wrong in practice

Almost every apportionment problem we see traces back to records, not rules. The three-bucket sort is only reliable if costs are tagged as they are posted; a business that dumps everything into one general pot has no honest basis for a split later, and a reviewer knows it. Build the coding into your chart of accounts so that direct-taxable, direct-exempt and residual costs separate themselves as the bookkeeping happens — that single habit removes most of the risk.

The second recurring failure is treating the periodic percentage as final and never running the wash-up, which leaves an unreconciled annual position on the record for a reviewer to test. The third is inconsistency — changing the basis of the split from period to period because it produces a better number, which is the surest way to attract questions. A documented method, applied the same way every period and reconciled annually, is the whole game. This is what a periodic VAT health check is designed to surface before the FTA does, and it is far cheaper to fix a method proactively than to defend a shaky one under review.

None of this sits in isolation from the rest of your VAT compliance. The apportioned recovery figure feeds straight into the input tax box on your return, so an unreliable split becomes an unreliable filing; our VAT return filing guide shows where the number lands and why the working behind it has to hold up. And because the calculation depends entirely on how costs are captured and coded, clean accounting and bookkeeping is not a nice-to-have here — it is the foundation the whole method stands on.

Bringing it together

For a partly exempt UAE business, input tax apportionment reduces to a short, ordered discipline. Sort every cost into one of three buckets as you post it: wholly taxable and recover in full, wholly exempt and recover nothing, or shared residual to be apportioned. Apply the input-based standard method to the residual pot each period. Run the annual wash-up to finalise the year, and watch for the actual-use adjustment where the standard result is materially off. And keep a special method in view only if you are in one of the sectors it was built for, or if the standard method keeps misstating your recovery.

The mistake is almost never the maths. It is leaving the whole exercise until a deadline forces it, with records that were never built to answer what each purchase was for. A business that codes its costs correctly from the first invoice does the hard part continuously, and the periodic calculation and year-end wash-up become confirmations rather than reconstructions.
