UAE Corporate Tax Calculation Formula: Step by Step

01

Start with Accounting Net Profit

Take the net profit (or loss) from your IFRS-compliant financial statements. This is your starting point, not revenue. A common mistake we see regularly: businesses confuse revenue with profit and dramatically overstate their expected tax liability. Corporate tax is calculated on profit after expenses, not on what came in the door. A company with AED 5 million in revenue and AED 4.8 million in expenses has a net profit of AED 200,000, which falls entirely within the 0% band. That company owes zero tax. But if they calculated on revenue, they would expect a bill of AED 416,250. The distinction matters.
02

Add Back Non-Deductible Expenses

Certain expenses recorded in your accounts are not deductible for corporate tax purposes. Add these back to net profit. This includes government fines and penalties, donations to non-qualifying entities, entertainment expenses exceeding the allowable 50% cap, personal expenses of owners or shareholders, and any expense not wholly incurred for business purposes.

This step catches many businesses off guard. They assume every expense on their P&L reduces their tax bill. It does not. A company that paid AED 50,000 in FTA penalties during the year must add that amount back to net profit when calculating taxable income. The penalty was a real cost to the business, but it is not a deductible cost for tax purposes. The full deductible vs non-deductible breakdown is covered in the reference table below.
03

Subtract Exempt Income

Deduct income that is exempt from corporate tax: qualifying dividends from UAE companies (5%+ ownership), qualifying participation income from foreign subsidiaries (5%+ ownership, held 12+ months), and qualifying foreign branch income (if taxed at 9% or higher abroad). The purpose of these exemptions is to prevent double taxation on income that has already been taxed or on returns from qualifying investments. If you are unsure whether a specific income stream qualifies, get it confirmed before filing. Claiming an exemption incorrectly inflates the error in the opposite direction from non-deductible expenses, and the FTA corrects both.
04

Apply Tax Loss Relief

If your business carried forward losses from prior tax periods, offset them against current taxable income. The maximum offset is 75% of taxable income in the current period. You cannot wipe out your entire taxable income with carried-forward losses. The remaining losses carry forward indefinitely, so they are not wasted. No carry-back is allowed under UAE corporate tax. And critically: if you did not declare losses in the tax period they occurred, you may not be able to claim them later. This is why accurate filing from your very first return matters.
05

Apply the Tax Rate

AED 0 to 375,000: taxed at 0%. Above AED 375,000: taxed at 9%.
This amount must be paid by the same deadline as your corporate tax filing: nine months from the end of your financial year. For the full calendar, see our corporate tax deadlines guide.

Corporate Tax Calculation Examples for UAE Businesses

Three worked examples covering the most common scenarios UAE businesses face. Each one walks through the full calculation from revenue to tax payable, including adjustments, loss relief, and the effective tax rate. If your situation matches one of these examples, you already have a template for your own computation.

 

Example 1: Mainland LLC (Standard Calculation)

Line Item Amount (AED)
Total Revenue 2,500,000
Total Deductible Expenses (1,800,000)
Accounting Net Profit 700,000
Add: Non-Deductible Expenses
(AED 15,000 fine + AED 5,000 personal)		 +20,000
Less: Exempt Income
(qualifying dividends)		 (50,000)
Adjusted Taxable Income 670,000
Less: Tax Loss from Prior Period
(available: 100,000; 75% cap: 502,500; full loss used)		 (100,000)
Final Taxable Income 570,000
Tax: 0% on first AED 375,000 0
Tax: 9% on AED 195,000
(570,000 minus 375,000)		 17,550
Corporate Tax Payable AED 17,550
Effective Tax Rate 2.51%

Notice the effective tax rate: 2.51%, not 9%. The AED 375,000 zero-rate band means the effective rate for most SMEs is significantly lower than the headline rate.

This is one of the most misunderstood aspects of UAE corporate tax. Many business owners hear “9%” and assume that is what they will pay on their entire profit. In reality, every business gets AED 375,000 of profit completely tax-free, and only the amount above that threshold is taxed.

For a company earning AED 570,000 in taxable income, that means paying AED 17,550 on AED 195,000 of income. The other AED 375,000 costs nothing.

Example 2: Qualifying Free Zone Person (QFZP)

De minimis check: Non-qualifying revenue (AED 120,000) equals 3.85% of total revenue (AED 3,120,000). This is below both the 5% threshold and the AED 5 million cap, so QFZP status is maintained.

If non-qualifying revenue had exceeded either threshold, the entire income would be taxed at 9% for five consecutive tax periods. That is not a one-year adjustment. It is a five-year reclassification that could cost hundreds of thousands in additional tax.

Example 3: Small Business Relief (SBR) Election

Different types of businesses operating in the UAE may fall under different corporate tax treatments depending on their legal structure, revenue levels, and regulatory status.

The following table summarizes how corporate tax generally applies to various categories of businesses.

Business Type Corporate Tax Treatment Key Conditions Practical Impact
Small businesses and startups 0% corporate tax on taxable income up to AED 375,000 Must meet taxable income threshold; may elect Small Business Relief if eligible Supports early-stage companies and SMEs during growth
Standard UAE mainland companies 9% corporate tax on taxable income above AED 375,000 Applies to most DED-licensed businesses in Abu Dhabi and across the UAE Main corporate tax regime for UAE businesses
Qualifying Free Zone Persons (QFZP) 0% corporate tax on qualifying income Must perform qualifying activities, maintain economic substance, and meet de minimis rules Allows Free Zone companies to maintain preferential tax treatment
Large multinational enterprises Subject to the Pillar Two global minimum tax framework Applies to multinational groups with global revenues ≥ EUR 750 million Ensures minimum global tax rate compliance (15%)

Without SBR, this company would owe AED 2,250 in corporate tax (9% on AED 25,000 above the AED 375,000 threshold).

With SBR elected, the liability is zero. But it must be actively selected on the return form. Forgetting to elect is one of the most common filing mistakes we see. For the full eligibility criteria, see our Small Business Relief guide.

SBR is not available to QFZPs, Tax Group members, or multinational enterprise group members. Losses cannot be carried forward from an SBR period.

What Expenses Are Deductible for UAE Corporate Tax?

Not every expense on your books reduces your tax bill. Knowing the difference before you file prevents corrections, penalties, and FTA queries after submission.

We have seen businesses claim AED 100,000+ in non-deductible expenses as deductions, resulting in understated taxable income that the FTA corrected with interest and penalties attached.

Deductible (Allowed) Non-Deductible (Add Back)
Employee salaries and benefits
(including WPS payroll)		 Government fines and penalties
Rent and utilities for business premises Donations to non-qualifying entities
Professional fees
(accounting, legal, audit)		 Owner/shareholder personal expenses
Depreciation of business assets Entertainment expenses exceeding 50% cap
Interest expense
(subject to 30% EBITDA cap for interest >AED 12M)		 Bribes, illegal payments
Marketing and advertising costs Expenses not incurred wholly for business purpose
Travel expenses for business purposes Income tax paid abroad
(claimed as Foreign Tax Credit instead)
Bad debt provisions
(if meeting CT Law criteria)		 Provisions for future losses
(unless meeting specific criteria)
R&D expenses Capital expenditures
(depreciated, not expensed)

De minimis check: Non-qualifying revenue (AED 120,000) equals 3.85% of total revenue (AED 3,120,000). This is below both the 5% threshold and the AED 5 million cap, so QFZP status is maintained.

If non-qualifying revenue had exceeded either threshold, the entire income would be taxed at 9% for five consecutive tax periods. That is not a one-year adjustment. It is a five-year reclassification that could cost hundreds of thousands in additional tax.
