Not every cost a business incurs reduces its Corporate Tax bill. Some expenses are fully deductible, some only partially, and some are disallowed entirely regardless of how genuinely business-related they are. Understanding UAE Corporate Tax deductions, and specifically the line between what reduces taxable income and what does not, is one of the most practical pieces of knowledge a business needs to get its Corporate Tax calculation right.
What Are Corporate Tax Deductions?
A Corporate Tax deduction is an expense that a taxable person is permitted to subtract from its accounting profit when calculating taxable income under Federal Decree-Law No. 47 of 2022. A deductible expense directly reduces the amount of income subject to Corporate Tax, while a non-deductible expense has no such effect and must be added back to accounting profit as part of the tax adjustment process. This distinction, deductible versus non-deductible, is the single most important concept in understanding how UAE Corporate Tax treats business spending.
General Deduction Rules
The core principle under UAE Corporate Tax Law is that an expense is deductible if it is incurred wholly and exclusively for the purposes of the taxable person’s business. This “wholly and exclusively” standard means an expense needs to have a genuine business purpose, not merely a tangential connection to the business, and it needs to relate entirely to the business rather than serving a mixed business and personal function without apportionment.
Beyond this general principle, the Corporate Tax Law specifically restricts or disallows certain categories of expense regardless of their business purpose, and applies partial limitations to others. This means an expense can satisfy the wholly-and-exclusively test and still be only partially deductible, or not deductible at all, if it falls into one of these specifically restricted categories.

Business and Operating Expenses
Ordinary business and operating expenses, the routine costs a business incurs to generate its income, are generally deductible provided they meet the wholly-and-exclusively standard. This typically covers day-to-day operational costs such as utilities, office supplies, insurance, marketing, and other expenses genuinely incurred in running the business.
Salaries
Employee salaries and related staff costs, including wages, allowances, and statutory benefits such as end-of-service gratuity, are generally deductible as a core cost of running a business, provided they represent genuine remuneration for services performed for the business.
Rent
Rent paid for business premises, whether office space, retail units, or warehousing, is generally deductible as an ordinary operating expense, provided the premises are genuinely used for business purposes.
Professional Fees
Fees paid for professional services genuinely used for business purposes, legal advice, accounting and audit services, tax advisory, and similar professional support, are generally deductible, reflecting their role as a legitimate cost of operating and maintaining compliance.

Depreciation
Capital expenditure on assets expected to provide benefit over multiple periods is not deducted in full in the period it is incurred. Instead, its cost is generally recognized over time through depreciation, spreading the deduction across the asset’s useful life in line with the accounting treatment applied and any specific rules the Corporate Tax Law sets for particular categories of asset.
Interest Expenses
Interest expenditure is generally deductible, but UAE Corporate Tax Law imposes a specific limitation on net interest deductions under what is commonly referred to as the General Interest Deduction Limitation Rule. Under this rule, net interest expenditure, interest expense minus interest income, is deductible up to the higher of AED 12,000,000 or 30 percent of the business’s tax-adjusted EBITDA for the period. Net interest expenditure exceeding this cap is disallowed for the period in which it is incurred, though disallowed amounts can generally be carried forward and deducted in future Tax Periods, subject to a maximum carry-forward period of 10 years.
A separate specific interest limitation rule can also restrict the deductibility of interest paid to certain related parties, generally where the arrangement does not serve a genuine, non-tax-motivated commercial purpose. Interest paid to a related party lender is generally not affected by this specific rule where that lender is itself subject to Corporate Tax, or an equivalent foreign tax, at a rate of at least 9 percent on the corresponding interest income.

Entertainment Expenses
Under Article 32 of the Corporate Tax Law, entertainment, amusement, and recreation expenditure incurred to entertain customers, shareholders, suppliers, and other business partners is deductible only up to 50 percent of the amount incurred. This category covers costs such as meals, accommodation, transportation, admission fees, and equipment or facilities used specifically for entertainment purposes.
This 50 percent cap applies as a flat statutory rule regardless of the total amount spent or how thoroughly the business purpose is documented; a business spending AED 10,000 on client entertainment and one spending AED 1,000,000 are both subject to the same 50 percent restriction. The remaining 50 percent must be added back to accounting profit as a non-deductible expense when calculating taxable income. Sponsorship expenditure that serves a genuine marketing or advertising purpose, rather than personal entertainment, is generally treated differently and can be deductible in full, since it falls outside the specific definition of entertainment expenditure.
Related-Party Expenses
Expenses incurred in transactions with related parties or connected persons are deductible under the same general principles that apply to any other business expense, but they carry an additional requirement: the transaction must be priced consistently with the arm’s length principle under the UAE’s transfer pricing rules. A related-party expense priced above what an independent party would have charged for the same goods or services can be challenged and adjusted, even where the underlying expense category, such as a management fee or intercompany service charge, would otherwise be fully deductible.
Businesses with material related-party expenses should be prepared to support the pricing of those transactions with appropriate documentation, since simply recording the expense in the accounts is not sufficient evidence that the deducted amount reflects an arm’s length price. A full discussion of these requirements is covered in our dedicated transfer pricing guide.
Mixed Business and Personal Expenses
Where an expense serves a mixed business and personal purpose, only the portion genuinely attributable to the business is deductible. A vehicle used partly for business travel and partly for personal use, for example, would generally only support a deduction for the business-use portion, with the personal-use portion treated as non-deductible and excluded from the calculation.
Apportioning a mixed expense requires a reasonable, defensible basis for splitting business and personal use, and the burden generally falls on the taxable person to support that apportionment if it is later questioned. Treating an expense as fully deductible simply because it passed through a business account, without a genuine business-use apportionment, is a common and avoidable error.
Non-Deductible Expenses
Certain categories of expense are specifically disallowed under UAE Corporate Tax Law regardless of their business purpose or documentation. This includes administrative penalties and fines imposed under UAE legislation, donations, grants, or gifts made to entities that are not qualifying public benefit entities, dividends and profit distributions, and bribes or other payments that would be considered illegal under applicable law.
Corporate Tax itself cannot be deducted as an expense in calculating taxable income, since allowing it to reduce its own calculation base would undermine the purpose of the tax entirely. Recoverable input VAT is also generally excluded from being claimed a second time as a Corporate Tax deduction, since it is already recovered through the VAT system rather than representing a genuine net cost to the business.
Deductible vs Non-Deductible: A Quick Comparison
| Deductible (Generally) | Non-Deductible or Limited |
|---|---|
| Salaries and staff costs | Fines and administrative penalties |
| Rent for business premises | Donations to non-qualifying entities |
| Professional fees | Dividends and profit distributions |
| Depreciation on business assets | Corporate Tax itself |
| Entertainment expenses (50% only) | Bribes and illegal payments |
| Interest (subject to GILDR cap) | Personal portion of mixed expenses |
Examples of Corporate Tax Deduction Treatment
Example 1: Entertainment. A business spends AED 100,000 on client entertainment during the period. Under Article 32, only AED 50,000 is deductible. The remaining AED 50,000 must be added back to accounting profit as a non-deductible expense.
Example 2: Interest. A business has net interest expenditure of AED 15,000,000 for the period, and its tax-adjusted EBITDA supports a 30 percent cap of AED 9,000,000. Since AED 15,000,000 exceeds both the AED 12,000,000 de minimis threshold and the 30 percent EBITDA cap, the deduction is limited to the higher of the two, AED 12,000,000. The remaining AED 3,000,000 is disallowed for the current period but can generally be carried forward for use in future periods.
Example 3: Mixed expense. A business owner uses a company vehicle for business travel 70 percent of the time and personal errands 30 percent of the time. Only 70 percent of the vehicle’s related costs, fuel, maintenance, and depreciation, are generally deductible, with the remaining 30 percent treated as a non-deductible personal expense.
