When calculating your UAE Corporate Tax liability, your taxable income is broadly your accounting profit, adjusted for specific items under the Corporate Tax Law. One of the most important adjustments involves the treatment of business expenses. Not every cost you incur is deductible against your taxable income.

Understanding the rules on deductibility is essential — both to avoid understating your tax (which creates a liability) and to ensure you are not missing legitimate deductions that reduce your bill.

The General Rule: Wholly and Exclusively for Business

An expense is deductible for UAE Corporate Tax purposes if it is incurred wholly and exclusively for the purposes of the taxable person’s business. This means:

  • The expense must be a genuine business cost — not personal.
  • It must be incurred to generate taxable income.
  • It must be properly documented with valid supporting evidence.

If an expense has both a business and a personal element, only the business portion is deductible.

Fully Deductible Expenses

The following categories of expenses are generally fully deductible, provided they meet the general rule above:

  • Salaries and wages: Employee remuneration, including allowances, bonuses, and end-of-service gratuity accruals, paid to employees for services rendered.
  • Rent: Lease payments for business premises used wholly for commercial purposes.
  • Cost of goods sold: Direct costs of inventory, raw materials, and goods purchased for resale.
  • Depreciation: Depreciation on business assets recognised under IFRS (or another approved accounting standard), subject to any capital allowance adjustments.
  • Professional fees: Amounts paid to accountants, auditors, lawyers, and consultants for genuine business services.
  • Utilities: Electricity, water, and telecommunications costs for business premises.
  • Marketing and advertising: Genuine costs of promoting the business’s products or services.
  • Insurance premiums: Business insurance, including professional indemnity, property, and liability cover.
  • Bank charges: Service fees and transaction charges relating to business accounts.
  • Subscriptions: Industry body memberships and business-related software or platform subscriptions.

Partially Deductible Expenses

Some expenses are recognised in principle but subject to specific restrictions under UAE Corporate Tax Law:

Entertainment and Hospitality — 50% Limitation

Expenses incurred for the purpose of entertaining clients, customers, or suppliers — such as meals, events, gifts, and hospitality — are only 50% deductible. This mirrors the approach in many other jurisdictions and reflects the personal enjoyment element often inherent in such expenditure.

Interest Expense — General Interest Deduction Limitation Rule (GIDLR)

Interest expense is deductible, but subject to a cap under the General Interest Deduction Limitation Rule. The net interest expense (i.e., interest expense minus interest income) that exceeds 30% of EBITDA (Earnings Before Interest, Tax, Depreciation, and Amortisation) is disallowed. Disallowed amounts can be carried forward for up to 10 years and utilised in future periods where capacity exists. A de minimis threshold of AED 12 million in net interest expense exists — below this, the 30% limitation does not apply.

Payments to related parties (connected persons) must be at arm’s length to be fully deductible. Where the FTA considers that a payment exceeds what an independent party would pay, the excess will be disallowed. Adequate transfer pricing documentation is required to support such deductions.

Non-Deductible Expenses

The following categories are explicitly disallowed by the UAE Corporate Tax Law:

1. Dividends and Profit Distributions

Distributions made to shareholders or partners are not a deductible business expense — they are an appropriation of profit, not a cost of generating it.

2. Fines and Penalties

Administrative and judicial fines, penalties, and surcharges imposed by government authorities (including FTA late payment fines) are not deductible. The public policy rationale is that the deterrent effect of a penalty should not be diminished by allowing it as a tax deduction.

3. Bribes and Corrupt Payments

Any payment made as a bribe, kickback, or illicit inducement is explicitly non-deductible and may also trigger criminal liability under UAE law.

4. Personal Expenses

Costs that are personal in nature and not related to the business — such as personal travel, home costs, or private schooling — are never deductible, even if paid through the company.

5. Donations, Grants, and Gifts to Non-Qualifying Entities

Charitable contributions are only deductible if made to Qualifying Public Benefit Entities approved and listed by the UAE Cabinet. Donations to other organisations or individuals are not deductible.

6. Corporate Tax Itself

The UAE Corporate Tax charge is not a deductible expense when computing taxable income. This is consistent with the treatment of income taxes in most jurisdictions.

7. Expenses Relating to Exempt Income

Costs that are directly attributable to generating income that is exempt from Corporate Tax (such as qualifying dividends or capital gains from a Participating Interest) cannot be deducted against taxable income.

Depreciation vs. Capital Allowances

It is important to note that while accounting depreciation is generally followed for tax purposes, the UAE Corporate Tax Law gives the FTA the authority to prescribe specific capital allowance rules for certain asset classes. Businesses should monitor any Ministerial Decisions or FTA guidance that establish asset-specific depreciation rates for tax purposes, which may differ from the accounting treatment.

Practical Steps to Maximise Legitimate Deductions

  1. Maintain complete records: Every deductible expense must be supported by a valid invoice, receipt, or contract.
  2. Separate personal and business finances: Use dedicated business bank accounts and credit cards to avoid the commingling of personal and business costs.
  3. Track entertainment expenses separately: Flag all client entertainment costs in your accounting system to apply the 50% restriction accurately.
  4. Monitor intercompany charges: Ensure related-party fees and service charges are priced at arm’s length and documented.
  5. Calculate your interest capacity: If you carry significant debt, model your EBITDA against your net interest expense to determine whether the GIDLR will apply.
