Two cycles into the UAE Corporate Tax regime, a pattern has emerged in the returns we review. The errors that produce overpayments are not, in the main, exotic. They are routine deductions that the taxpayer has been conservative about, has not realised they were entitled to, or has captured incorrectly in the underlying financial statements.
This listicle covers the eight deductions we see most commonly under-claimed in UAE Corporate Tax computations, with notes on the basis for each and the documentation a firm should keep to support the claim. None of them are aggressive positions - these are the deductions the rules expressly contemplate, that the FTA does not contest, and that nonetheless quietly cost taxpayers money each year.
1. Owner-director salaries at full market value
The owner-director's salary is deductible to the extent it corresponds to market value for the services rendered. Many owner-managed UAE businesses pay their owner-directors a nominal salary on the basis that "we are the same person as the company" - and then leave the deduction on the table.
A properly benchmarked owner-director salary, supported by reference to market data for an equivalent role in an equivalent business, is a routine and substantial deduction. The benchmark does not need to be elaborate - a defensible market reference, applied consistently, and documented in a board minute at the time of the decision, is enough. The deduction is then a straightforward operating expense.
2. Pre-incorporation and pre-trading expenditure
Expenditure incurred before the entity's legal incorporation or before the start of trading is frequently treated as a non-deductible founder cost. Under the UAE rules, pre-incorporation expenditure that would have been deductible if incurred after incorporation, and that is incurred on the entity's behalf, can be deducted in the first period of trading, subject to the usual wholly-and-exclusively-for-business-purposes test.
The typical categories - legal fees for incorporation, professional fees for licence application, market research and feasibility studies, initial branding and website development, pre-launch staff training - are all routine deductions. The supporting file should evidence that the expenditure was incurred for the entity's business, and a short capitalisation policy should set out the treatment.
3. Net interest on intra-group financing
The interest deduction limitation under Article 30 caps net interest at the greater of 30% of EBITDA or AED 12 million. For SMEs comfortably below the AED 12 million safe harbour, the limitation rarely bites - but the underlying interest is also frequently under-claimed.
The most common pattern is an intra-group loan that has not been formally documented, on which interest has not been charged or has been charged at a below-market rate. The arm's length interest is the deductible amount, and the failure to charge it leaves the deduction unclaimed. Document the loan, set an arm's length rate, accrue the interest, and claim the deduction.
4. Bad debt relief at the right point in time
A bad debt expense is deductible under the UAE rules where the debt is genuinely bad and the entity has taken reasonable steps to recover it. Many firms wait too long to recognise the bad debt, holding the receivable on the balance sheet for one or two years past the point at which collection is realistically unachievable.
A standing year-end review of aged receivables, with a documented basis for writing off the genuinely bad balances, accelerates the deduction into the period in which the loss is economically suffered rather than deferring it to a later year. The supporting file should show the collection steps taken and the basis for the write-off conclusion.
5. Staff training, professional development, and CPD costs
Staff training costs, professional development, CPD subscriptions, and exam fees for relevant qualifications are deductible operating expenses. They are also frequently buried in catch-all "general administrative" lines and partially missed at the tax computation stage, particularly where the training is delivered abroad and the invoices are in a foreign currency.
A clear sub-ledger for staff development costs makes the deduction visible. The same goes for relevant subscriptions - to professional bodies, journals, software training platforms, and continuing education programmes. These are not advisory positions; they are routine deductions that benefit from being properly captured.
6. Repairs and maintenance distinct from capital expenditure
The boundary between repairs (deductible as incurred) and capital expenditure (depreciated over time) is a perennial source of under-claimed deductions. The conservative default is to capitalise - and where the underlying spend was genuinely a repair to restore the asset to its prior condition rather than an improvement, that conservative default defers the deduction unnecessarily.
A defensible position is to write a short capitalisation policy, apply it consistently, and treat each material item against the policy. Routine maintenance of plant and equipment, paintwork, minor lease-hold improvements that do not extend the useful life, and replacement of consumable parts are typically deductible. The savings are not glamorous but they compound year after year.
7. Foreign tax suffered on foreign-source income
A UAE-resident taxable person with foreign-source income - service revenue from overseas customers, foreign dividends not within the participation exemption, foreign interest - can credit foreign tax suffered against the UAE tax payable on the same income, up to the UAE tax on that income.
The credit is frequently overlooked. The supporting file should include the foreign tax certificate (or equivalent evidence), the calculation of the foreign-source income, and the calculation of the UAE tax attributable to that income. For groups with material foreign activity, build the foreign tax credit working into the standing year-end checklist.
8. Realisation basis adjustments for unrealised losses
A taxpayer can elect to be taxed on a realisation basis, meaning unrealised gains and losses on capital assets and liabilities are excluded from taxable income until realised. The election is a one-time choice at the start of the first tax period.
Where unrealised losses are sitting in the financial statements - typically on investment portfolios, on foreign exchange-denominated assets, or on financial instruments held at fair value - the realisation basis defers the relief for those losses until the asset is sold. Conversely, where the entity is sitting on material unrealised losses that are likely to crystallise in the near term, the non-realisation default basis brings forward the deduction. Either way, the election should be a deliberate choice, modelled with the underlying portfolio, rather than an unconsidered default.
The pattern behind the under-claims
Across these eight deductions, the common thread is that the underlying expenditure exists, is genuine, and is wholly and exclusively for the business - but is either captured in the wrong line of the accounts, deferred unnecessarily, or simply not surfaced at the tax computation stage. The defence is not aggressive positions. It is a clean working paper file, a standing year-end checklist, and a partner-level review that asks "what have we missed?" rather than simply "have we got the disallowances right?".
Two errors not to make in the other direction
It is worth noting two deductions that are commonly over-claimed and that the FTA does routinely contest:
- Entertainment expenditure - 50% of which is disallowed under Article 32, and which is frequently claimed in full
- Donations and grants to non-qualifying public benefit entities - which are non-deductible, and which are frequently claimed where the recipient is not on the qualifying list
How Accupe helps
Accupe is the practice management layer that lets a firm run a year-end deduction review across the portfolio. Smart Boards govern the checklist per client, AI document analysis with source citation accelerates the review of expense ledgers and contracts, and the Compliance Radar surfaces clients whose computations are approaching the filing deadline without a partner review on file. Accupe does not compute deductions or file the return - your filing tool and EmaraTax do that - but the firm-side workspace is what makes a standing review possible at portfolio scale.
