Provision vs Accrual: Why AED 100,000 Is Added Back but AED 50,000 Is Not (UAE)

Nova Business Services LLC closed its year with two year-end charges: a AED 100,000 general provision for unspecified risks, and a AED 50,000 accrual for the audit fee, where the audit work was done before year-end and invoiced just after.

The two look similar in the accounts but are opposites for tax. The accrual is a real liability for services received; the provision is a buffer against things that may never happen.

Only the AED 100,000 is added back, giving taxable income of AED 1,150,000 and tax of AED 69,750.

The AED 100,000 general provision is added back: it estimates unspecified future costs and is not incurred expenditure.

The AED 50,000 audit accrual needs no adjustment: the audit services were received in the period, creating an incurred liability even though the invoice arrived later.

For the complete rulebook behind these adjustments, see our guide to deductible expenses.

Each step below carries its own arithmetic, so the full trail from the starting figure to the tax payable is visible.

Most tax adjustments are about timing, not about whether an amount is ever recognised. General provisions, inventory write-downs and impairments anticipate future events; tax waits for the event. The add-back now and the deduction later net to the same total, but the period's tax is completely different.

The realisation-basis election under Ministerial Decision No. 134 of 2023 systematises this for unrealised gains and losses on assets and liabilities: elect it and both are deferred until realisation; do not elect and both are recognised as they arise. The election is symmetric, so it can raise current tax in a loss year.

Depreciation is the notable non-timing item with no adjustment at all: the UAE has no separate capital allowances, so accounting depreciation on business assets is simply deductible. Adjustments arise only where the asset is not used in the business or the charge is invented.

Accruals for goods and services already received are deductible when the liability is incurred, even if invoiced later. That is why the audit fee accrual stays deducted while the general provision goes back: one records a real obligation, the other a buffer.

Impairment reversals follow the same symmetry as write-down reversals: where the original impairment was added back under the realisation election, the reversal is removed as an unrealised gain. Consistency across periods is what keeps the election defensible; selective treatment invites challenge.

Capital versus revenue character still matters at the boundary. Expenditure that creates an enduring asset is capitalised and depreciated, not deducted outright, and attempting to expense capital items is a different error from the timing adjustments above. The two issues should be tested separately for every major spend.

The background rules are set out in our guide to taxable income.

Treating every provision like an accrual is the most common error. A provision needs a crystallised liability to be deductible; an accrual already has one. The labels in the accounts do not decide which is which.

Claiming invented tax depreciation on top of accounting depreciation is the second. There is no second depreciation system, and the extra charge is added back in full.

Forgetting the symmetry of the realisation election is the third. Deferring a write-down feels like a cost, but the matching reversal is then removed too; the election must be judged over the asset's whole life.

A fourth mistake is adjusting the same item twice: once as a provision and again under the realisation election. Each amount gets one adjustment; the two regimes must be reconciled so nothing is double-counted.

Our guide to exempt income covers the underlying provisions in more depth.

Each provision adjusted on the return should appear on a provision schedule: the amount, the reason for add-back, and the expected crystallisation event. When the cost is later incurred, the schedule shows the corresponding deduction, keeping the timing trail complete across years.

Where the realisation election is in place, keep an election register of deferred amounts by asset: write-downs, impairments and reversals tracked until realisation. The register is what proves the symmetry the election requires.

Review asset classifications annually: an asset that moves from investment property to inventory, for example, can change which timing rules apply. The tax treatment follows the facts each period, not the original label.

Finally, reconcile the tax provision schedules to the accounts every year-end: every general provision in the statements should appear on either the add-back schedule or the deductible-accrual schedule, with nothing unclassified. Unreconciled differences are where errors hide.

This page works one computation end to end: the scenario sets out the starting figures, the adjustments section applies each tax correction with its article reference, and the step-by-step section shows every line of arithmetic. The key figures are collected here for quick reference.

Use this page as a template by replacing the scenario's numbers with your own while keeping the same adjustment logic: the method, the article references and the order of operations transfer directly to any similar computation.

When you adapt the template, re-check each adjustment against the current facts rather than copying the amounts. A fine that was non-deductible here might be breach-of-contract compensation there; entertainment is always halved but only genuine client entertainment belongs in that line; and exempt income must meet its article's conditions in your period, not just resemble last year's.

Pay particular attention to the order of operations when you reuse the method. Adjustments come first to reach taxable income, then loss relief and the interest limitation apply to that figure, and only then do the 0% and 9% rate bands divide it. Reordering these layers is the fastest way to turn a right method into a wrong answer.

Finally, keep the evidence behind every figure you substitute. The FTA tests computations from the documents outward: invoices behind expenses, dividend vouchers behind exempt income, valuations behind market-value adjustments, and assessments behind foreign tax credits. A template with good numbers and no evidence is only half a return.

Double-check the 75% cap arithmetic whenever losses are involved: the cap is 75% of taxable income before loss relief, not after, and it is tested separately for each period. A cap computed on the wrong base either wastes losses or claims too much, and both errors compound across years.
