Every dirham you fail to claim as a deduction under UAE corporate tax is a dirham you hand to the Federal Tax Authority for free. Since Federal Decree-Law No. 47 of 2022 took effect on 1 June 2023, every mainland and qualifying free-zone business with taxable income above AED 375,000 owes 9% corporate tax – and the size of that bill depends almost entirely on how well you separate deductible expenses from non-deductible ones.
This guide walks through the full list of deductible and non-deductible expenses, the specific FTA rules that govern each category, and the documentation you need to survive an audit. (If you have not yet filed, start with our step-by-step EmaraTax filing walkthrough.). No filler – just the rules, the numbers, and the practical steps.
The Core Rule: “Wholly and Exclusively” for Business
Article 28 of the Corporate Tax Law sets the foundation. An expense is deductible only if it is incurred “wholly and exclusively” for the purpose of the taxable person’s business. That phrase does heavy lifting – it means the FTA can reject any expense where the primary purpose was personal, even if it had a secondary business benefit.
The expense must also be actually incurred (not just accrued without payment) and must not fall into any of the categories the law specifically blocks. If both conditions are met, the deduction reduces your taxable income and, by extension, your 9% tax liability.
Expenses That Are 100% Deductible
The following categories qualify for full deduction, provided you hold proper supporting documents (invoices, contracts, payroll records, bank statements):
1. Employee Salaries, Benefits, and End-of-Service Gratuity
All compensation paid to employees – base salary, housing allowance, transport allowance, medical insurance premiums, annual airfare, overtime, bonuses, and end-of-service gratuity – is fully deductible. The key requirement: the employee must be on your WPS-registered payroll, and the payment must be documented through your payroll system and bank transfers.
Owner salaries are deductible too, but only if the owner holds a formal employment contract with the company, receives a salary that reflects market rates, and the payment runs through WPS. If the FTA determines the salary is inflated beyond what the role warrants, the excess portion may be disallowed.
2. Rent and Premises Costs
Office rent, warehouse rent, co-working space fees, Ejari-registered lease payments, and associated costs like DEWA (utilities), Etisalat/du (telecom), and chiller charges are all fully deductible. For home offices, you can claim a proportional percentage – for example, if your home office occupies 20% of your apartment, you can deduct 20% of rent and utilities, but only if that space is used exclusively for business.
3. Marketing and Advertising
Google Ads spend, social media advertising, website development and hosting, SEO services, trade show participation fees, print and digital marketing, and agency retainers are all 100% deductible. Keep the ad platform invoices, agency contracts, and payment receipts – the FTA expects clear documentation linking the spend to business promotion.
4. Professional and Advisory Fees
Legal fees, audit fees, tax advisory fees, accounting and bookkeeping charges, management consultancy, and recruitment agency fees are fully deductible. This includes fees paid for corporate tax registration, VAT filing, and FTA compliance work.
5. Depreciation of Business Assets
The cost of fixed assets – vehicles, machinery, office furniture, IT equipment, software licenses – is deductible through depreciation over the asset’s useful life. The UAE corporate tax law follows IFRS accounting standards, so you should apply the depreciation method (straight-line or reducing balance) consistent with your audited financial statements. Land is not depreciable.
6. Insurance Premiums
Business insurance premiums – professional indemnity, property insurance, trade credit insurance, vehicle fleet insurance, and mandatory employee medical insurance – are fully deductible. Personal life insurance for the owner is not deductible unless it is part of a broader employee benefits package.
7. Customs Duties and Import Costs
Customs duties paid on goods imported for resale or for use in business operations are 100% deductible. This is particularly relevant for trading companies, retailers, and manufacturers importing raw materials. Keep your customs declarations and payment receipts as supporting evidence.
8. Business Travel
Flights, hotel stays, ground transport, and per-diem allowances for business trips are fully deductible – but only the business portion. If an employee adds personal vacation days to a business trip, the accommodation and meals for those extra days must be excluded. The FTA expects a clear separation, ideally with a travel policy that documents purpose, dates, and approvals.
9. Staff Welfare and Internal Entertainment
Office refreshments, team lunches, company events (such as annual gatherings and team-building activities), staff training programs, and employee welfare programs are 100% deductible. The distinction from client entertainment (which is only 50% deductible) is critical – internal staff expenses get the full deduction because they serve employee retention and operational purposes.
10. Donations to Qualifying Public Benefit Entities
Donations made to FTA-approved charities and public benefit organizations – such as Dubai Cares, UAE Red Crescent Authority, and other entities listed in Cabinet Decision No. 37 of 2023 – are 100% deductible. The donation must be made to an entity on the approved list; donations to non-approved organizations are entirely non-deductible.
Expenses That Are Only 50% Deductible
Client and Business Partner Entertainment
Article 28 of the Corporate Tax Law caps entertainment deductions at 50%. (For the VAT side of these same expenses, see our guide on VAT recovery on entertainment, vehicles, and staff costs.) This covers any expenditure incurred to entertain customers, shareholders, suppliers, or business partners, including meals at restaurants, hotel accommodation for visiting clients, event tickets, conference hospitality, and the use of entertainment facilities or equipment.
Example: Your company spends AED 10,000 hosting a client dinner at a Dubai restaurant. Only AED 5,000 is deductible. The remaining AED 5,000 is added back to your taxable income. This rule exists because the FTA recognizes that entertainment spending often has a personal or non-commercial element mixed in with the business purpose.
To maximize what you can claim, keep detailed records that link each entertainment expense to a specific business purpose – the client name, the meeting agenda, and the business outcome discussed. Vague descriptions like “client dinner” without specifics are easier for the FTA to challenge.
Expenses That Are Completely Non-Deductible
Article 33 of the Corporate Tax Law lists expenses that cannot be deducted under any circumstances, regardless of how they are recorded in your financial statements:
1. Fines and Penalties
Traffic fines, late filing penalties from the FTA, municipality violations, labor law penalties, and any government-imposed fines are non-deductible. The only exception: amounts paid as compensation for damages or breach of contract (such as a settlement payment to a former employee) are deductible because they represent a commercial obligation, not a penalty.
2. Personal Expenses
Any expense that benefits the owner or a related person in their personal capacity – a family holiday booked through the company, a personal vehicle purchased in the company’s name but used for private purposes, tuition fees for the owner’s children, or personal mobile phone bills – is entirely non-deductible. Mixed-use assets (a car used 60% for business and 40% personally) require apportionment; only the business portion is deductible.
3. Donations to Non-Approved Entities
Donations, grants, or gifts made to any entity that is not on the FTA’s list of Qualifying Public Benefit Entities are non-deductible. This includes contributions to international NGOs not registered in the UAE, sponsorships of individuals, or charitable payments to organizations that lack FTA approval – even if the cause is genuine.
4. Bribes, Illegal Payments, and Kickbacks
Any payment that violates UAE law or international anti-corruption standards is non-deductible. This includes facilitation payments, under-the-table kickbacks, and any form of bribery – regardless of whether the payment was made inside or outside the UAE.
5. Dividends and Profit Distributions
Dividends paid to shareholders are not business expenses – they are distributions of after-tax profit. They cannot be deducted from taxable income. Similarly, withdrawals by partners in a partnership are treated as profit distributions, not salary expenses, unless a formal employment arrangement exists.
6. Payments to Related Free Zone Persons at 0% Tax
If your mainland company makes payments to a related party operating in a free zone that benefits from the 0% corporate tax rate, those payments are non-deductible. This prevents businesses from shifting profits to related free-zone entities to reduce their mainland tax bill. However, if the free zone entity has a mainland branch, the portion of the payment allocated to that branch can be deducted.
Interest Deduction – The 30% EBITDA Cap
Interest on business loans, bank facilities, and credit lines is deductible – but not without limits. The UAE follows the OECD Base Erosion and Profit Shifting (BEPS) Action 4 framework, which caps net interest deductions at 30% of EBITDA (earnings before interest, taxes, depreciation, and amortization).
Example: Your company earns AED 1,000,000 in EBITDA and pays AED 400,000 in net interest. The deductible amount is capped at AED 300,000 (30% of AED 1,000,000). The remaining AED 100,000 is added back to taxable income. Any disallowed interest can be carried forward to future tax periods, subject to conditions.
Banks, insurance companies, and regulated financial institutions are exempt from this cap. Small businesses may also qualify for a de minimis threshold that allows full deduction of interest below a certain amount, regardless of the EBITDA ratio.
For related-party loans, the FTA applies additional scrutiny. Interest on intra-group borrowings (such as a loan from a parent company to a subsidiary) is only deductible if the borrowing has a legitimate commercial reason and the lending entity is subject to UAE corporate tax (or an equivalent tax elsewhere) at a rate of at least 9%.
Documentation the FTA Expects During an Audit
Claiming a deduction without proper documentation is the fastest way to have it reversed during an FTA audit. For every deductible expense, you should maintain:
- Tax invoices or receipts showing the supplier’s TRN (Tax Registration Number)
- Signed contracts or service agreements
- Bank statements or payment confirmations showing the actual transfer
- Board resolutions or management approvals for significant expenditures
- Payroll records and WPS reports for salary deductions
- Travel policy documents and trip reports for business travel claims
- Asset registers with depreciation schedules for capital asset deductions
- Entertainment logs linking each expense to a specific client or business purpose
The FTA requires businesses to retain financial records for a minimum of 7 years from the end of the relevant tax period. If you cannot produce supporting documents during an audit, the deduction will be disallowed – even if the expense was legitimate.
Penalties for Incorrect Deduction Claims
Getting deductions wrong carries real financial consequences. Under FTA Administrative Penalties, incorrectly claiming a non-deductible expense can result in penalties of up to AED 20,000 plus retroactive tax payments on the disallowed amounts. If the FTA determines the error was intentional (for example, consistently claiming personal expenses as business costs), the penalties increase significantly and may include criminal referral.
The most common audit triggers include entertainment expenses with vague business justifications, related-party transactions priced above market rates, sudden spikes in deductible expenses relative to revenue, and owner salary deductions that exceed comparable market rates for the role.
Five Common Deduction Mistakes UAE Businesses Make
Claiming 100% of entertainment expenses. Many business owners do not realize client entertainment is capped at 50%. They record a AED 15,000 client dinner as a full deduction, when only AED 7,500 qualifies. Review your entertainment ledger before filing.
Mixing personal and business vehicle costs. A company car used partly for school runs and weekend errands is a mixed-use asset. Without a logbook tracking business vs. personal kilometers, the FTA may disallow the entire deduction – not just the personal portion.
Deducting fines as “operating expenses.” Traffic fines, visa penalties, and municipality violations sometimes get coded to general expense accounts. These are non-deductible regardless of where they appear in the chart of accounts.
Ignoring the interest cap. Businesses with high debt loads often deduct all interest payments without checking the 30% EBITDA threshold. If your net interest exceeds 30% of EBITDA, the excess must be added back to taxable income.
Donating to non-approved charities. A donation to an international NGO or a community fundraiser that lacks FTA approval is non-deductible, even if the receipt looks official. Always verify the entity appears on the FTA’s Qualifying Public Benefit Entity list before claiming.
