The UAE's corporate tax system has been live since June 2023. Most businesses have now filed at least one return. But here is what the first round of filings made clear: the difference between a manageable tax bill and an expensive correction often comes down to how a business handles its deductions.
Getting deductions right is not a bookkeeping formality. It is the single most direct lever you have over how much tax you actually pay. Every dirham of legitimately claimed expense is a dirham the FTA does not tax at 9%. Getting them wrong, on the other hand, is getting riskier by the month. The FTA conducted 93,000 inspection visits in 2024, a 135% increase from the prior year. Its 2023 to 2026 strategy confirms that audits are risk driven, not random. And one of the top focus areas in corporate tax reviews is the add-back of incorrectly claimed deductions: entertainment expenses booked at 100% instead of 50%, personal costs disguised as business expenses, penalties recorded as operating costs, and interest that exceeds the statutory caps.
This guide walks through what the law actually allows, what it blocks, and where the grey areas sit that tend to attract attention during an FTA review. It is based on Federal Decree-Law No. 47 of 2022, specifically Articles 28 through 33, and reflects all updates through March 2026 including Ministerial Decision No. 173 of 2025 on deemed depreciation for investment property.
If you are preparing for your first or second corporate tax return, or if your accountant has flagged deductions you are unsure about, this is where to start.

1. The Golden Rule: Wholly and Exclusively for Business
Article 28 of the Corporate Tax Law sets the foundation for every deduction you will ever claim. For an expense to be deductible, it must meet three conditions.
First, it must be incurred wholly and exclusively for business purposes. No personal element. Not partially for personal benefit. The primary motive must be generating taxable income.
Second, it must be revenue in nature, not capital. You cannot expense a long term asset purchase in full. Capital items are recovered through depreciation over their useful life.
Third, it must be incurred during the relevant tax period. Most businesses use accrual accounting, meaning expenses are recognised when incurred, not when paid. Businesses under Small Business Relief with revenue under AED 3 million may use cash basis accounting instead.
If an expense serves a dual purpose, part business and part personal, you can claim the identifiable business portion. The law allows this. But the burden of proof is on you. You need documentation that makes the split clear and reasonable. This principle sounds simple. In practice, it is where most mistakes happen.
2. What You Can Deduct: The Full Breakdown
The following categories are generally deductible, provided they meet the Article 28 test and are supported by proper documentation. This is based on the FTA's published guidance on determination of taxable income and the PwC UAE corporate tax deductions summary.
Staff Costs
Salaries, wages, bonuses, overtime, end of service gratuity provisions, medical insurance, housing allowances, and other employee benefits are deductible. This is typically the largest deduction for most UAE businesses, and the FTA rarely challenges it as long as the amounts are reasonable for the role and the market.
One important nuance: staff entertainment such as team lunches, company events, and staff retreats is fully deductible at 100%. This is different from client entertainment, which is capped at 50%. Many businesses miss this distinction and either under-claim staff entertainment or over-claim client entertainment. Both create problems.
Rent and Occupancy
Office rent, warehouse leases, co-working space memberships, and associated costs like maintenance, security, and cleaning are all deductible if the premises are used for business operations. If you work from home and your trade licence is linked to a virtual office or flexi-desk, only the portion directly related to the business is deductible. The FTA will expect you to demonstrate how you calculated the split.
Utilities and Operational Overheads
Electricity, water, internet, phone bills, and similar running costs are deductible when incurred for business purposes. If a phone line or internet connection serves both personal and business use, apportion it and claim the business share only. Your monthly bookkeeping records should clearly track this separation.
Marketing and Advertising
Digital marketing spend, social media campaigns, print advertising, sponsorships, promotional materials, agency fees, SEO services, and trade show costs are all deductible. The key requirement: the spend must be clearly tied to promoting the business, not personal brand building unrelated to the taxable entity.
Professional and Government Fees
Legal fees, audit fees, accounting fees, tax advisory fees, regulatory filing costs, and consulting fees are deductible, provided they relate to the business's operations. Keep engagement letters and invoices that clearly describe the business purpose. Government fees are deductible too: trade licence renewal, visa costs for employees, business registration fees, and similar regulatory charges incurred in the ordinary course of business.
Business Travel
Flights, hotels, ground transport, and per diem costs for business travel are deductible. Only the business portion qualifies. If you extend a business trip by three personal days, those extra days are not deductible. Keep trip itineraries, meeting records, and receipts separated by purpose.
Depreciation and Amortisation
Capital assets such as equipment, vehicles, furniture, fit-outs, and machinery cannot be expensed in full in the year of purchase. Instead, you recover the cost through depreciation over the asset's useful life, following IFRS standards. The same applies to intangible assets like patents, trademarks, and software licences, which are recovered through amortisation.
Tax depreciation follows your IFRS depreciation method, with one exception: capitalised interest on qualifying assets must be assessed separately under the interest deduction rules.
New for 2025: Ministerial Decision No. 173 of 2025 introduced an irrevocable election for businesses that recognise gains and losses on a realisation basis. If you hold investment property at fair value under IFRS, you can now claim a deemed depreciation deduction. This is a meaningful change for real estate holding companies. It is irrevocable, so take professional advice before electing.
Bad Debts
Bad debts are deductible, but only once formally written off in the accounts. Provisions for doubtful debts are trickier. They are deductible only if commercially reasonable and specifically related to taxable business income. General provisions not tied to identified receivables may be challenged during an FTA audit.
Donations to Qualifying Public Benefit Entities
Donations are deductible, but only if made to a UAE approved public benefit entity such as Dubai Cares or the Emirates Red Crescent. Donations to entities that are not on the approved list are non-deductible, full stop. This catches many businesses by surprise.
Irrecoverable VAT
If you incur input VAT that you cannot recover under the VAT law, for example because it relates to exempt supplies, that irrecoverable VAT is deductible as a business expense for corporate tax purposes. Recoverable input VAT is not deductible because it is not a cost to you. You get it back through your quarterly VAT return.
This creates a direct link between your VAT return accuracy and your corporate tax position. If you under-claim input VAT on your VAT return, you may be able to pick up the difference as a corporate tax deduction. If you over-claim, you have a problem on both sides.
3. What Is Partially Deductible
Client Entertainment: The 50% Cap
Article 32 of the Corporate Tax Law limits entertainment expenses to 50% deductibility. This applies to costs incurred to entertain customers, shareholders, suppliers, and other business partners: meals, accommodation, event tickets, transportation, and similar hospitality.
Worked example: You host a dinner for a client. The bill is AED 2,000. You can deduct AED 1,000. The other AED 1,000 is added back to your taxable income.
The 50% cap does not apply to internal staff events. A company iftar for your team is 100% deductible. A client iftar is 50% deductible. This is one of the most common errors the FTA flags in corporate tax reviews. Many businesses expense all entertainment at 100% without distinguishing between staff and client facing events. Get your chart of accounts right from the start, and make sure your bookkeeping separates these categories.
Interest Expenses: Two Limitation Rules
Interest is deductible, but the UAE applies two sets of restrictions to prevent excessive debt financing from eroding the tax base.
General Interest Deduction Limitation Rule (GIDLR): Your net interest expense (interest paid minus interest earned) is deductible up to the higher of 30% of your tax adjusted EBITDA, or AED 12 million. If your net interest expense is below AED 12 million, the cap does not apply at all. This means most SMEs will never be affected. Any disallowed interest can be carried forward for up to 10 subsequent tax periods.
Special Interest Deduction Limitation Rule (SIDLR): Interest on loans from a related party is not deductible if the loan was used to pay dividends or profit distributions to a related party, repurchase or reduce share capital for a related party, make capital contributions to a related party, or acquire an ownership interest in a person who is or becomes a related party. There is one exception: the SIDLR does not apply if the related party lender is subject to corporate tax or equivalent at a rate of at least 9% in its own jurisdiction.
Practical example: Your UAE company borrows AED 5 million from its parent company in the UK to fund a dividend distribution back to that same parent. The interest on that loan is not deductible because the loan was used to pay dividends to a related party. Structuring intercompany financing without understanding the SIDLR is one of the fastest ways to create an audit risk. If your business has related party transactions, your transfer pricing documentation needs to address this directly.
4. What You Absolutely Cannot Deduct
Article 33 provides a hard list. No exceptions, no apportionment, no workarounds. If you claim any of these, the FTA will disallow them and may impose penalties on top.
Fines and penalties. Traffic fines, late filing penalties, regulatory sanctions: none of these are deductible. The only exception is amounts awarded as compensation for damages or breach of contract. A court ordered payment to settle a commercial dispute is deductible. An FTA penalty for filing your VAT return late is not.
Bribes and illicit payments. Any payment that is illegal under UAE or foreign law is non-deductible. This is absolute.
Dividends and profit distributions. Payments to shareholders as dividends or profit distributions are not business expenses. They are distributions of after-tax profit and cannot reduce your taxable income.
Owner withdrawals. If you are a sole proprietor or a partner in an unincorporated partnership, any money you withdraw from the business for personal use is non-deductible. This matters particularly for freelancers and sole practitioners. You cannot pay yourself a "salary" and deduct it if your business structure does not support that treatment. Only employees of a juridical person (a company) can receive deductible salaries.
UAE corporate tax itself. The tax you pay under the Corporate Tax Law is not deductible against your own taxable income. You cannot deduct your tax bill to reduce your tax bill.
Recoverable input VAT. If you can recover VAT on a purchase, that VAT is not a cost to you and is therefore not deductible. Only irrecoverable VAT qualifies, as covered above.
Foreign income tax. Tax imposed on you outside the UAE is not deductible as an expense. However, it may qualify for a foreign tax credit under double taxation agreements. These are different mechanisms: a credit reduces your tax liability directly, while a deduction only reduces taxable income.
Expenses related to exempt income. If you earn income that is exempt from corporate tax, for example qualifying dividend income from a participation, the expenses you incur to earn that income are also non-deductible. You cannot claim deductions against income that is not being taxed.
5. The Grey Areas That Trigger Audits
The deductions above are relatively black and white. Where businesses get into trouble is in the grey areas where judgement is involved and the FTA has reason to look more closely. Based on what tax practitioners are reporting from the first wave of corporate tax reviews, these are the areas drawing the most scrutiny.
Owner Salaries in SMEs
If you are the owner-director of an LLC and you pay yourself a salary, that salary is technically deductible, provided it is reasonable for the role and commercially justifiable. The FTA will compare it to what the market rate would be for a similar position. An owner paying themselves AED 80,000 per month for running a two-person consultancy will face questions.
For connected persons (owners, directors, relatives within the fourth degree of kinship), the transfer pricing rules apply. Any compensation paid must be at arm's length. Excessive payments will be disallowed and added back to taxable income.
Payments to Free Zone Entities
If your mainland company pays a related free zone entity that enjoys 0% tax as a QFZP, the mainland entity's deduction may be restricted. The logic: you are shifting profit from a 9% environment to a 0% environment within the same group. The FTA will scrutinise whether the payment reflects a genuine service at a fair market price. Without proper transfer pricing documentation, expect this to be flagged.
Personal Expenses Booked as Business Costs
Company cars used for personal driving. Phone bills that cover the whole family. Travel upgrades with no business justification. These are the low hanging fruit in an FTA review. The FTA has access to your VAT filings, bank statements, and financial records. Inconsistencies between what you report as business expenses and what the data shows are easy to spot.
This risk is increasing because the FTA is now cross referencing VAT and corporate tax returns. If your VAT return shows AED 120 million in taxable supplies but your corporate tax return reports AED 100 million in revenue, that mismatch will be flagged. This was highlighted specifically in Alvarez & Marsal's analysis of FTA audit strategy for 2026.
Capital Expenditure Misclassified as Revenue
Buying a new laptop is a capital expense. Repairing a broken laptop is a revenue expense. The distinction matters because capital items must be depreciated over their useful life, not expensed immediately. Misclassifying capital expenditure as revenue is a common error in first time filings. It inflates your deductions in year one and understates them in future years. The FTA's taxable income guide specifically addresses this distinction.
Related Party Management Fees Without Substance
Paying your parent company or a sister entity a "management fee" is deductible only if the fee reflects a genuine service, is priced at arm's length, and is supported by documentation showing what was actually delivered. The FTA treats management fees without a documented benefit test as one of the highest risk items in a corporate tax review. If you cannot demonstrate what service was provided and why the price is fair, the deduction will be disallowed.
6. New for 2026: The R&D Tax Credit
Effective for tax periods starting on or after 1 January 2026, the UAE is introducing an R&D tax incentive. According to the UAE Government's official announcement, the credit will be expenditure based, offering a potential 30% to 50% tax credit on qualifying R&D expenditure. The credit may be refundable depending on your revenue and number of UAE based employees.
Qualifying activities must align with the OECD's Frascati Manual guidelines and must be conducted within the UAE. This is separate from normal expense deductions. It is a credit that directly reduces your tax liability, not just your taxable income. Eligible expenses typically include researcher salaries, materials, cloud and lab costs, and outsourced R&D (subject to conditions).
Final implementation details and Ministerial Decisions are expected from the Ministry of Finance in coming months. If your business involves any form of innovation, product development, or technical problem solving, this is worth tracking closely with your corporate tax advisor.
7. Documentation Requirements: What the FTA Expects
Claiming a deduction without documentation is the same as not having one. Under the Corporate Tax Law, you must maintain records that substantiate every deduction for at least seven years. The FTA can request these records within 30 days of an audit notification.
For each deductible expense, you should be able to produce the invoice or receipt showing the amount, the supplier, and the date. You should have a clear record of the business purpose, whether that is stated on the invoice, in an internal approval, or through supporting documents like meeting agendas, travel itineraries, or engagement letters. Your chart of accounts should map each expense to the correct category so that restricted deductions (entertainment at 50%) and non-deductible items (fines, dividends) are separated at the point of entry, not adjusted at year end.
Businesses that rely on shoebox accounting or reconstruct their records at filing time are exposing themselves to disallowed deductions and penalties. A clean, well maintained bookkeeping system is not a cost. It is insurance against an audit adjustment that could cost far more.
8. Worked Example: How Deductions Affect Your Tax Bill
Consider a Dubai based consultancy with the following simplified financials for its 2025 tax period:
Total revenue: AED 5,000,000. Salaries (3 employees): AED 1,200,000, fully deductible. Office rent: AED 300,000, fully deductible. Marketing: AED 150,000, fully deductible. Client entertainment: AED 60,000, only AED 30,000 deductible (50% cap). Traffic fine: AED 5,000, non-deductible. Owner salary: AED 480,000, deductible if arm's length for the role. Professional fees (audit, legal, tax): AED 80,000, fully deductible. Depreciation on office fit-out: AED 40,000, deductible per IFRS schedule.
Total deductible expenses: AED 2,280,000. Taxable income: AED 5,000,000 minus AED 2,280,000 equals AED 2,720,000. Tax at 0% on first AED 375,000: AED 0. Tax at 9% on remaining AED 2,345,000: AED 211,050.
If this business had incorrectly claimed the full AED 60,000 of entertainment and the AED 5,000 fine as deductible, it would have understated its tax by approximately AED 3,150. That seems small, but the FTA penalty for an incorrect return is AED 500 for a first offence and AED 2,000 for a repeat, plus 14% per annum on any underpaid tax from April 2026 onwards under Cabinet Decision No. 129 of 2025. The compliance cost of getting it wrong always exceeds the effort of getting it right.
Frequently Asked Questions
What expenses are deductible under UAE corporate tax?
Expenses incurred wholly and exclusively for business purposes are deductible. This includes salaries, rent, utilities, marketing, professional fees, business travel, depreciation, bad debts written off, donations to approved entities, and irrecoverable input VAT. The expense must be revenue in nature (not capital) and relate to the tax period in question.
Are entertainment expenses fully deductible?
No. Client entertainment, including meals, hospitality, events, and gifts for customers, suppliers, and shareholders, is limited to 50% deductibility under Article 32 of the Corporate Tax Law. Staff entertainment, such as team lunches and internal company events, is fully deductible at 100%.
Can I deduct my own salary as a business owner?
It depends on your business structure. If you are a sole proprietor or partner in an unincorporated partnership, withdrawals from the business are non-deductible under Article 33. If you are an employee of a juridical person (such as an LLC), your salary is deductible provided it is at arm's length, meaning reasonable for the role and consistent with market rates.
What is the interest deduction limit under UAE corporate tax?
Net interest expense is deductible up to the higher of 30% of your tax adjusted EBITDA or AED 12 million. If your net interest expense is below AED 12 million, the cap does not apply. Disallowed interest can be carried forward for up to 10 tax periods. Additional restrictions apply to interest on related party loans used for specific purposes like dividend distributions.
Are fines and penalties deductible?
No. Fines and penalties imposed for violations of law are non-deductible under Article 33. This includes traffic fines, FTA late filing penalties, and regulatory sanctions. The only exception is amounts paid as compensation for damages or breach of contract, which remain deductible.
How long must I keep records to support my deductions?
The Corporate Tax Law requires businesses to maintain all records, invoices, contracts, and supporting documentation for a minimum of seven years. The FTA can request these documents within 30 days of issuing an audit notification. Failure to produce records can result in disallowed deductions and additional penalties.
What happens if the FTA disallows a deduction?
If the FTA determines that a claimed deduction does not meet the requirements of Articles 28 to 33, the expense is added back to your taxable income. This increases your tax liability for the period. You may also face a penalty of AED 500 for a first incorrect return (AED 2,000 for repeat offences), plus 14% per annum interest on any unpaid tax from April 2026 under the revised penalty regime.
Does the new R&D tax credit replace normal expense deductions?
No. The R&D tax credit is an additional incentive, not a replacement. R&D related expenses that meet the normal deductibility requirements under Article 28 can still be deducted. The credit, offering 30% to 50% on qualifying R&D expenditure, provides a further reduction in your tax liability on top of the standard deduction. Final implementation rules are expected from the Ministry of Finance in 2026.
Conclusion: Get Your Deductions Right from the Start
The corporate tax deduction rules are not complicated in principle. The challenge is in the detail, the documentation, and the discipline of applying the rules consistently from day one, not at year end. Businesses that maintain clean records, separate personal from business expenses, correctly classify entertainment costs, and track interest limitations will file with confidence and face minimal audit risk.
Businesses that leave this to the last minute, or rely on assumptions about what is deductible without checking the law, will find that the FTA's expanding audit programme catches up with them. The 2026 tax environment rewards preparation. The cost of a proper review is always less than the cost of a correction.
