When preparing a corporate tax return in the UAE, businesses start with their net profit as per accounting standards. However, the amount on which tax is eventually calculated—taxable profit—can be markedly different from this figure. Specific tax adjustments are required, and missteps are common, especially for growing businesses encountering the new regime for the first time.

The starting point: accounting net profit

The calculation always begins with accounting net profit for the relevant period, as shown in the business's financial statements. These statements must be prepared in line with the accounting standards specified in UAE Ministerial Decision No. 114 of 2023. The businesses will use either IFRS or IFRS for SMEs, as required by law, depending on their revenue and this forms the foundation for further tax adjustments.

Adjustments to arrive at taxable income

Accounting profit is not the end of the story. The UAE corporate tax law prescribes additional steps—some to add back income or expenses, others to deduct or exempt certain amounts. Frequently overlooked areas include:

Exempt income

Some types of income are specifically exempt from UAE corporate tax. For instance, dividends received from other UAE resident companies are excluded. Income from a "participating interest"—an ownership interest meeting requirements under Article 23 of the law—may also qualify for exemption. In each such case, the exempt income must be deducted from the accounting profit when determining taxable profit.

Example: If a business has AED 1,000,000 of accounting profit, but this includes AED 200,000 in dividends from a resident subsidiary, that AED 200,000 is excluded from taxable profit.

Non-deductible expenses

Certain expenses that might be recognised for accounting purposes are not allowable for tax.

For example:

  • Penalties and fines are not deductible.
  • Donations, grants or gifts are generally not deductible unless given to a qualifying public benefit entity.
  • Bribes and other illegal payments are expressly non-deductible.

All such expenses must be added back to accounting profit when calculating taxable profit.

Limits on entertainment expenses

Only 50% of entertainment expenses (such as meals, accommodation, event or hospitality costs provided to customers, suppliers, etc.) can be deducted. If a company accounts for AED 100,000 of such entertainment in its profit and loss account, only AED 50,000 is deductible. The remaining AED 50,000 must be added back when determining taxable profit.

Interest deduction limitations

There are both general and specific rules restricting how much interest a business can deduct for tax purposes.

  • Generally, net interest expense (interest expense minus interest income) is deductible only up to 30% of adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation). Interest above this cap is not deductible in the current year and must be carried forward, subject to rules.
  • There are specific exclusions and reliefs for banks and certain other financial institutions, as well as exceptions in some intragroup situations.

If net interest expense is AED 300,000 but 30% of adjusted EBITDA is AED 200,000, only AED 200,000 is deductible.

Provisions and impairment losses

Provisions for bad debts are only deductible when the debts are actually written off in accordance with relevant accounting standards and substantiated by appropriate evidence. General provisions or expected loss provisions, even if recognised in financial statements, are not deductible for tax purposes unless actually written off. When a bad debt previously written off is subsequently recovered, the amount recovered must be included as taxable income in that period.

Unrealised gains and losses

Only certain unrealised gains and losses, mainly those in respect of financial instruments measured at fair value and recognised through profit or loss, are taken into account. Unrealised gains or losses recognised directly in equity or other comprehensive income are typically adjusted out of taxable income, unless they relate to assets or liabilities disposed of in the same period.

Non-taxable and prior period items

Income and expenses relating to prior periods, which may be restated as per accounting standards, can trigger further adjustments. Likewise, items not related to the business activity are not recognised for tax purposes.

Common areas where mistakes occur

Many businesses, especially those new to corporate tax, get caught out by:

  • Failing to adjust for exempt dividend income and participating interest exemption.
  • Deducting full entertainment costs instead of limiting to 50%.
  • Not applying the general interest deduction limitation, especially in leveraged businesses.
  • Claiming deductions for fines or charitable donations to non-qualifying entities.
  • Failing to add back non-deductible provisions, especially for doubtful debts.

Putting it together: how the calculation looks

The overall process for many businesses involves these steps:

  1. Start with accounting net profit (from financial statements).
  2. Deduct exempt income (e.g., qualifying dividends).
  3. Add back non-deductible expenses (e.g., penalties, non-qualifying donations).
  4. Apply limits to entertainment and interest deductions.
  5. Adjust for bad debts, unrealised gains/losses, and any prior-period or non-business items as required.

Businesses are expected to keep clear documentation and must be able to show the basis of all adjustments if queried by the FTA.

Tax rates and the threshold

After determining taxable profit, the relevant rate is applied:

  • 0% on taxable profit up to AED 375,000.
  • 9% on taxable profit above AED 375,000.

A different rate applies to certain large multinationals as specified by the UAE government.

These rates—and the adjustments described above—are the core of what bridges accounting profit and taxable profit under UAE corporate tax law. For all but the smallest business, these adjustments are critical to getting the final tax computation correct.
