Answer first: Under UAE corporate tax, an expense is deductible only if it is incurred wholly and exclusively for the business, is not capital in nature, and is properly supported by records. On that basis salaries, rent, utilities, marketing, professional fees, depreciation, and qualifying bad debts are fully deductible. Client entertainment is capped at 50%, and net interest is limited to 30% of EBITDA (with an AED 12 million de minimis safe harbour). Some costs are never deductible: fines and penalties, bribes, owner drawings, dividends, corporate tax itself, recoverable input VAT, personal expenses, and the disallowed half of entertainment. Getting this split right is what separates a defensible tax return from an FTA add-back.

Who this is for
UAE founders, SME owners, finance managers, and free zone company teams who need to know which costs reduce their corporate tax bill and which will be added back before they file. If you are preparing your first return under Federal Decree-Law No. 47 of 2022, this is the reference to keep beside your profit and loss statement.
The General Rule: Wholly and Exclusively for Business
Federal Decree-Law No. 47 of 2022 sets a single governing test for deductibility. An expense is deductible if it is incurred wholly and exclusively for the purposes of the business and is not capital in nature. Everything else in this guide is an application or an exception to that rule.
"Wholly and exclusively" means the cost must serve the business and only the business. A mixed-purpose cost - part business, part personal - is only deductible to the extent it relates to the business, and you must be able to show the split. A director's phone bill used half for family is not fully deductible just because the invoice is in the company name.
"Not capital in nature" separates day-to-day running costs from the acquisition of long-term assets. You cannot deduct the full purchase price of a vehicle, a building, or expensive equipment in the year you buy it; instead you deduct depreciation or amortisation over the asset's life. The revenue cost of using assets is deductible; the capital cost of buying them is spread out.
The third pillar is evidence. A deductible expense you cannot support with an invoice, contract, or proof of payment is exposed. The FTA can disallow costs that are not adequately documented, so the deduction rules and your bookkeeping discipline are two sides of the same obligation.
The Deductibility Reference Table
The table below is the fastest way to place a cost. Use it as a first pass, then confirm the detail in the sections that follow.
| Fully deductible | Partially deductible / capped | Never deductible |
|---|---|---|
| Staff salaries, wages, and end-of-service benefits | Client entertainment, meals, hospitality (50% only) | Fines and penalties for breaking a law (not contractual compensation) |
| Owner salary at market value, with a contract | Net interest expense (capped at 30% of EBITDA; AED 12m de minimis) | Bribes and other illicit payments |
| Office rent, utilities, and service charges | Mixed-use costs (business portion only) | Dividends and profit distributions to owners |
| Marketing, advertising, and website costs | Owner drawings for personal use | |
| Professional fees (legal, accounting, consultancy) | Corporate tax itself and non-creditable foreign income tax | |
| Depreciation and amortisation per accounting standards | Recoverable input VAT (not an expense) | |
| Bad debts written off where conditions are met | Expenses that relate to exempt income | |
| Software, subscriptions, and bank charges | Personal and private expenses of owners or staff |

What Is Fully Deductible
Most ordinary trading costs are deductible in full because they pass the wholly-and-exclusively test cleanly.
Salaries and staff costs. Wages, salaries, bonuses, allowances, pension and end-of-service contributions, and other genuine employment costs are fully deductible - usually the single largest deduction on an SME return.
Owner and director salary. A salary paid to the business owner is deductible, but only where it reflects a market rate for the work performed and is properly documented: an employment contract, payroll records through WPS where applicable, and evidence the money was paid. Without those, the FTA can recharacterise the payment as a profit distribution and disallow it. This is one of the most common SME exposures, covered again below.
Rent, utilities, and premises costs. Office or warehouse rent, DEWA/SEWA/ADDC utilities, service charges, and cleaning are deductible.
Marketing and advertising. Digital ads, agency fees, printing, sponsorships tied to business promotion, and website costs are deductible. Note the difference from entertainment: promoting the business to the market is marketing; hosting a specific client to dinner is entertainment, capped at 50%.
Professional fees. Legal, accounting, audit, tax advisory, and consultancy fees incurred for the business are deductible.
Depreciation and amortisation. You cannot expense a capital asset outright, but the depreciation or amortisation charged in your accounts under IFRS or IFRS for SMEs is deductible - this is how the cost of long-term assets reaches taxable income over time.
Bad debts. A trade debt written off as irrecoverable is deductible where the conditions are met - the debt was previously recognised as income, genuine recovery efforts have been made, and the write-off is properly recorded. A general, unevidenced provision is weaker and may be challenged.
Other running costs. Software subscriptions, bank charges, insurance, telecoms, and consumables are deductible where they serve the business.
Partially Deductible and Capped Items
Two categories are deductible but limited, and both are frequent sources of add-backs.
Entertainment - the 50% cap. Only 50% of entertainment, amusement, and recreation expenditure is deductible. This covers hospitality provided when receiving customers, suppliers, shareholders, or other business contacts: client meals, event hospitality, tickets, and similar costs. The remaining 50% is added back to taxable income. There is no de minimis - the cap applies from the first dirham. A common mistake is logging client entertainment as "marketing" to sidestep the cap; the FTA looks at the substance of the cost, not the ledger label.
Interest - the general interest deduction limitation. Interest is a legitimate cost, but net interest expense is capped at 30% of EBITDA (earnings before interest, tax, depreciation, and amortisation). To keep the rule proportionate, a de minimis safe harbour lets a business deduct net interest up to AED 12 million in a tax period regardless of the 30% ceiling. Interest above the applicable limit is disallowed for the period and may be carried forward under current rules. Specific relief exists for certain categories of business and for particular financing arrangements, so treat the fine detail as per current FTA guidance and hedge accordingly.
For a worked example of how these caps flow from accounting profit to tax payable, see how to calculate UAE corporate tax.
What Is Never Deductible
These items are added back to accounting profit in every case.
Fines and penalties. Amounts imposed for breaching a law or regulation - traffic fines, municipal penalties, and FTA tax penalties - are non-deductible. The exception is compensation paid under a contract, for example damages for late delivery or breach of a commercial agreement, which is a normal business cost and remains deductible.
Bribes and illicit payments. Any payment that constitutes a criminal offence under UAE law is fully non-deductible.
Dividends and profit distributions. Returns paid to owners on their capital are a distribution of profit, not a cost of earning it, and are never deductible.
Owner drawings. Money the owner takes out of the business for personal use is not an expense. Running personal spending through the company and expensing it is a classic SME error that inflates deductions and invites adjustment.
Corporate tax and non-creditable foreign tax. The corporate tax charge on your own income is not deductible. Foreign income taxes that cannot be credited against UAE corporate tax are also disallowed.
Recoverable input VAT. VAT you can reclaim as input tax on your VAT return is not a cost - it flows through the VAT system, not the profit and loss account. Only irrecoverable VAT (for example blocked input tax) can sit as an expense.
Expenses relating to exempt income. Costs incurred to earn income that is exempt from corporate tax - such as qualifying dividends or exempt participation gains - are not deductible against taxable income.
Personal and private expenses. Any cost that is not wholly and exclusively for the business fails the general rule. Personal travel, family costs, and private-use portions of mixed expenses are outside the deduction.
The disallowed half of entertainment. The 50% of entertainment that fails the cap is added back like any other non-deductible item.
UAE considerations
Two provisions deserve specific attention for UAE businesses, and both connect back to your records.
Related-party payments must be at arm's length. Payments to owners, connected persons, and group companies are only deductible to the extent they reflect what independent parties would have agreed - the arm's-length principle. An inflated management fee to a shareholder, or above-market rent paid to a related landlord, can be adjusted down. This is the transfer pricing dimension of deductibility; see the transfer pricing guide for the documentation expected.
Documentation is the deduction. Under the FTA regime, an expense you cannot evidence is an expense you may lose. Keep invoices, contracts, proof of payment, and a clear business rationale for each material cost, and retain them for the required period. The mechanics of this sit in your day-to-day process - see record keeping for UAE corporate tax and Finsera's bookkeeping service. Because deductibility is judged on an accruals basis, the choice between accrual and cash accounting also affects when a cost lands in the right period.
Treat this guide as a planning aid. For any fine-grained position - the exact scope of the interest rules, bad-debt conditions, or pre-incorporation treatment - verify against live FTA or Ministry of Finance guidance before you file.
Common SME Mistakes
The disallowances above are rarely deliberate. They come from a handful of recurring habits:
- Mixing personal spend through the business. Groceries, personal travel, and family costs booked as company expenses. These fail the wholly-and-exclusively test and are drawings, not deductions.
- Undocumented cash expenses. Costs with no invoice or proof of payment. Even a genuine business cost is exposed if you cannot evidence it.
- Owner salary with no employment contract. Paying yourself a "salary" that is really a drawing, with no contract, payroll record, or market-rate justification.
- Entertainment logged as marketing. Client dinners and hospitality reclassified to avoid the 50% cap. The FTA tests substance, not the account name.
- Pre-incorporation costs with no paper trail. Genuine set-up costs lost because the invoices were never kept or linked to the business.
Key takeaways
- Deductibility turns on one rule: the cost must be wholly and exclusively for the business and not capital in nature, with evidence to prove it.
- Salaries (including a market-rate, documented owner salary), rent, utilities, marketing, professional fees, depreciation, and qualifying bad debts are fully deductible.
- Entertainment is 50% deductible; net interest is capped at 30% of EBITDA with an AED 12 million de minimis safe harbour.
- Fines, bribes, dividends, drawings, corporate tax, recoverable input VAT, exempt-income costs, and personal expenses are never deductible.
- Related-party payments must be at arm's length, and every deduction stands or falls on your documentation.
Common questions
Is client entertainment deductible under UAE corporate tax?
Only 50% of client entertainment, hospitality, meals, and recreation expenses are deductible. The other 50% must be added back to taxable income. This cap applies to costs incurred when receiving customers, suppliers, shareholders, or other business partners - there is no minimum amount below which the full cost is allowed.
Can I deduct my own salary as a business owner in the UAE?
Yes, an owner's salary is deductible if it is set at a market rate for the work performed and is properly documented with an employment contract, payroll records, and evidence of payment. Payments that are really profit distributions dressed up as salary, or amounts above market value, can be challenged and disallowed by the FTA.
Are fines and penalties deductible under UAE corporate tax?
No. Fines and penalties imposed for breaking a law or regulation are non-deductible - traffic fines, municipal penalties, and FTA tax penalties all fall here. The one exception is compensation paid under a contract for damages or breach, which is a normal business cost and remains deductible.
Is corporate tax itself a deductible expense?
No. UAE corporate tax charged on your own income cannot be deducted in calculating taxable income. Foreign taxes on income that are not creditable against UAE corporate tax are also non-deductible. VAT that you can recover as input tax is not an expense at all and should never be deducted.
Can I deduct expenses I paid before the company was set up?
Pre-incorporation and pre-trading expenses can be deductible if they were incurred wholly and exclusively for the business that later begins trading, are revenue in nature, and are properly evidenced. Treatment follows the applicable accounting standards and current FTA guidance, so keep the invoices and a clear record of what each cost related to.
Is interest on a business loan fully deductible in the UAE?
Interest is deductible, but net interest expense is capped at 30% of EBITDA under the general interest deduction limitation. A de minimis safe harbour lets businesses deduct net interest up to AED 12 million regardless of the 30% cap. Interest above the limit is disallowed and may be carried forward under current rules.
