How to Calculate Your Corporate Tax in the UAE: Free Calculator
Every business registered for corporate tax in UAE needs to calculate its tax liability accurately before filing. Errors in your taxable income computation do not just cost you money. They trigger FTA corrections, 14% annual interest on underpayments, and potential audits.
Use our free calculator below to estimate your corporate tax liability in under a minute. It handles all four scenarios that other UAE calculators miss: standard mainland calculation, Qualifying Free Zone Person income split, Small Business Relief election, and tax loss carry-forward with the 75% cap applied automatically.

UAE corporate tax is calculated by taking accounting net profit from IFRS-compliant financial statements, adding back non-deductible expenses, subtracting exempt income, applying tax loss relief (capped at 75%), then applying 0% on the first AED 375,000 of taxable income and 9% on the remainder.
Formula: Tax = (Taxable Income minus AED 375,000) x 9%.

01 Your Numbers
FTA non-deductible items — tap to expand
- Fines & penalties — administrative penalties, FTA late-payment fines, traffic violations, and any punitive charge imposed by a UAE government authority (Art. 33).
- Bribes & illicit payments — any payment that constitutes a bribe or is otherwise unlawful under UAE law (Art. 33).
- Owner / shareholder personal expenses — living costs, school fees, personal travel, or any expense that benefits the owner rather than the business.
- Entertainment — 50 % cap — meals, hospitality, recreation, and client entertainment are only 50 % deductible. The remaining 50 % is non-deductible (Ministerial Decision No. 126 of 2023, Art. 4). Enter the disallowed half here.
- Donations to non-qualifying entities — gifts or contributions to organisations not listed as Qualifying Public Benefit Entities under Cabinet Decision No. 37 of 2023.
- Related-party payments not at arm's length — any amount paid to a connected person exceeding the arm's length price is disallowed. Includes management fees, service charges, royalties, and interest charged above market rate (Art. 34–36, Transfer Pricing rules).
- Dividends & profit distributions — distributions to shareholders are not a deductible expense (treatment is at equity level, not P&L).
- Capital expenditure expensed directly — capex must be capitalised and depreciated; amounts expensed in full in the period are non-deductible to the extent they exceed the allowable depreciation charge.
- Provisions not meeting FTA criteria — general provisions (e.g. blanket bad-debt reserves) without specific identification are disallowed. Only specific, individually assessed provisions qualify.
- Interest subject to General Interest Limitation Rule (GILR) — net interest expense exceeding 30 % of EBITDA is disallowed where net interest exceeds AED 12M. Applies to large entities; most UAE SMEs fall below the threshold (Art. 30).
- Expenses with no business purpose — any cost not wholly and exclusively incurred for the purposes of the taxable business is disallowed (Art. 28).

UAE Corporate Tax Calculation Formula: Step by Step
Step 1: 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.
Step 2: 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.
Step 3: 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.
Step 4: 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.
Step 5: 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)
| Line Item | Qualifying Income (AED) | Non-Qualifying Income (AED) |
|---|---|---|
| Revenue | 3,000,000 | 120,000 |
| Expenses | (2,000,000) | (80,000) |
| Net Profit | 1,000,000 | 40,000 |
| Tax Rate | 0% | 9% (above AED 375,000) |
| Tax Payable | AED 0 | AED 0 (40,000 < 375,000) |
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.
For the full eligibility conditions, see our Free Zone corporate tax guide.
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) |
Maintain detailed records and invoices for every claimed deduction. The FTA can request supporting documentation during audits, and disallowed deductions increase your taxable income retrospectively.
Professional accounting services ensure proper expense classification from day one, so your books support your return without requiring reclassification at filing time.
