UAE Corporate Tax: What SMEs Need to Know in 2026
Corporate tax is 9% on taxable income above AED 375,000. Here are the registration deadlines, filing dates and penalties SMEs need to plan around.
UAE Corporate Tax: What SMEs Need to Know in 2026
UAE corporate tax is 9% on taxable income above AED 375,000. Below that figure the rate is 0%. Returns are due nine months after your tax period ends, and missing the registration deadline costs AED 10,000 on its own. That is the whole regime in four sentences. The rest of this article is the detail SMEs get wrong.
Understanding UAE Corporate Tax Basics
Corporate tax took effect on 1 June 2023 under Federal Decree-Law No. 47 of 2022. It applies in every emirate, mainland and free zone alike.
Who is subject to corporate tax in the UAE?
Corporate tax applies to:
The law covers resident and non-resident juridical persons earning income from UAE sources.
Corporate Tax Rates in UAE
Two rates. That is it.
0% on taxable income up to AED 375,000
9% on taxable income above AED 375,000
Separately, Small Business Relief can be elected where revenue is AED 3,000,000 or less. Elect it and you are treated as having no taxable income for that period. It is a relief you claim, not a rate — and it is tested on revenue, not profit. Businesses confuse it with the AED 375,000 band constantly.
Large multinationals meeting specific criteria may fall under a different rate.
Key Corporate Tax Thresholds and Exemptions
The AED 375,000 Threshold
AED 375,000 is the number to know. It splits your taxable income in two:
Example calculation:
Exemptions and Special Categories
Certain entities and income types are exempt:
Government entities and wholly government-owned companies receive automatic exemption.
Extractive businesses remain subject to emirate-level taxation.
Qualifying free zone persons may benefit from 0% tax on qualifying income, provided they:
Investment income from qualifying shareholdings may be exempt under participation exemption rules.
Corporate Tax Registration Process
When to Register
Every taxable person must register, including businesses that will pay nothing. Zero tax does not mean zero obligation.
The Federal Tax Authority sets registration deadlines by category, and they differ for existing businesses, newly incorporated entities and foreign entities acquiring a UAE presence. Check the deadline that applies to your licence rather than assuming a general rule. Miss it and the penalty is AED 10,000.
How to Register
The corporate tax registration process follows these steps:
Step 1: Access the FTA portal at tax.gov.ae
Step 2: Provide business information:
Step 3: Submit required documentation:
Step 4: Receive Tax Registration Number (TRN)
Your TRN is essential for filing returns and official correspondence.
Tax Periods and Filing Deadlines
Understanding Tax Periods
UAE corporate tax follows a tax period aligned with your financial year:
Standard tax period: 12 months matching your financial year
Short tax period: Possible in first year or when changing financial year
Financial year-end: Can be any date; most businesses use December 31
Filing Deadlines
Tax return filing: within 9 months after the tax period ends
Tax payment: due on the same date as the return
Three penalties are commonly confused. They are separate and they can apply at the same time.
Late registration: AED 10,000. One-off, charged for missing the registration deadline.
Late filing: AED 500 for each month, or part month, for the first twelve months. From month thirteen it rises to AED 1,000 per month.
Late payment: 14% annual interest on the unpaid tax.
Example timeline:
Calculating Taxable Income
Starting with Accounting Net Profit
Corporate tax calculation begins with accounting net profit per IFRS-aligned financial statements, then applies adjustments:
Accounting net profit
+/- Tax adjustments
= Taxable income
× Tax rate (0% or 9%)
= Corporate tax liability
Common Adjustments
Your taxable income differs from accounting profit due to these adjustments:
Non-deductible expenses:
Tax depreciation: May differ from accounting depreciation
Transfer pricing adjustments: Required for related party transactions
Loss carryforward: Unlimited carryforward of tax losses to future periods
Record Keeping and Documentation Requirements
What Records to Maintain
UAE corporate tax law requires businesses to maintain:
Financial records:
Supporting documentation:
Tax records:
How Long to Keep Records
Minimum retention period: 7 years from end of relevant tax period
Records must be:
Transfer Pricing and Related Party Transactions
When Transfer Pricing Rules Apply
Transfer pricing affects SMEs with:
Arm's Length Principle
All related party transactions must be priced at arm's length - the price independent parties would agree to in comparable circumstances.
Required actions:
Maintain transfer pricing documentation showing:
Larger transaction volumes and group structures attract more extensive documentation requirements. Confirm which tier applies to you before the year closes, not after.
Compliance Strategies for SMEs
Implement Strong Bookkeeping Systems
Tax compliance is a bookkeeping problem before it is a tax problem. Bad books produce bad returns.
Use cloud accounting software like QuickBooks Online or Zoho Books for:
Maintain monthly discipline:
Separate business and personal expenses completely to avoid disallowed deductions.
Plan Throughout the Year
Year-end is too late. By then the transactions have happened and the options are gone.
Quarterly reviews: Assess taxable income projection and estimated tax liability
Expense timing: Strategic timing of deductible expenses
Loss relief: Decide which year to apply carried-forward losses against
Transfer pricing: Document related party transactions contemporaneously

Conclusion
At 9% above AED 375,000, the rate is not the hard part. The compliance calendar is. Registration has its own deadline and its own AED 10,000 penalty. Filing is nine months after year-end, and every month you slip past it costs AED 500, then AED 1,000 from month thirteen.

Frequently asked questions
- What is the corporate tax rate in the UAE?
- UAE corporate tax is 0% on taxable income up to AED 375,000 and 9% on taxable income above that figure. The 9% applies only to the portion over AED 375,000, so a business with AED 500,000 of taxable income pays 9% on AED 125,000, which is AED 11,250.
- What is Small Business Relief in UAE corporate tax?
- Small Business Relief is an election available where revenue is AED 3,000,000 or less, and it treats the business as having no taxable income for that period. It is tested on revenue, not profit, and it is a relief you claim rather than a tax rate. It is separate from the AED 375,000 zero-rate band.
- When is the UAE corporate tax return due?
- The corporate tax return is due within nine months of the end of your tax period, and payment is due on the same date. For a business with a 31 December year-end, that means the return and the tax are both due by 30 September of the following year.
- What are the penalties for late corporate tax registration and filing?
- Missing the registration deadline costs a one-off AED 10,000. Late filing is a separate penalty of AED 500 per month for the first twelve months, rising to AED 1,000 per month from month thirteen. Unpaid tax also attracts interest at 14% a year, and all three can apply together.
- Do free zone companies pay UAE corporate tax?
- Free zone companies are within the corporate tax regime and must register. A Qualifying Free Zone Person can pay 0% on qualifying income if it keeps adequate substance, earns only qualifying income, follows transfer pricing rules and does not elect mainland treatment. Non-qualifying income, such as most mainland business, is taxed at 9%.
