UAE Corporate Tax is an important compliance requirement for businesses operating in the UAE. New companies should understand how the Corporate Tax regime may apply to them, when registration is required, how taxable income is determined and what ongoing filing and record-keeping obligations may apply.
Understanding UAE Corporate Tax
UAE Corporate Tax is a federal tax on the taxable income of businesses and certain other taxable persons. It applies to tax periods beginning on or after 1 June 2023, subject to the provisions of the UAE Corporate Tax Law and related decisions.
For most taxable persons, taxable income up to and including AED 375,000 is subject to Corporate Tax at 0%, while the portion of taxable income exceeding AED 375,000 is generally subject to Corporate Tax at 9%.
1. Corporate Tax Is Based on Taxable Income
Corporate Tax is not simply calculated on the total revenue received by a business.
Taxable income generally starts with the accounting income of the business for the relevant tax period, with adjustments made as required under the Corporate Tax Law.
This means businesses should maintain proper accounting records and understand the difference between revenue, accounting profit and taxable income.
2. Corporate Tax Registration
Businesses and other persons that fall within the scope of UAE Corporate Tax should determine whether they are required to register with the Federal Tax Authority and ensure registration is completed within the applicable timeframe.
Registration requirements and deadlines can depend on the type of taxable person and the circumstances of the business. Businesses should therefore check the latest FTA requirements rather than relying on general assumptions.
3. Free Zone Businesses Have Specific Rules
Being established in a UAE Free Zone does not automatically mean that all income is exempt from Corporate Tax.
A Qualifying Free Zone Person may benefit from a 0% Corporate Tax rate on Qualifying Income where the applicable conditions are satisfied. Taxable income that does not qualify can be subject to Corporate Tax at 9%.
Free Zone businesses should therefore assess their activities, transactions and eligibility carefully under the applicable Corporate Tax rules.
4. Tax Returns and Payment Deadlines
Corporate Tax compliance continues after registration.
Taxable Persons are generally required to submit their Corporate Tax Return and pay any Corporate Tax due within nine months from the end of the relevant Tax Period.
For example, where a company's Tax Period ends on 31 December, the normal filing and payment deadline would generally fall on 30 September of the following year.
Businesses should identify their Tax Period and applicable deadline early so that accounting records and tax calculations can be prepared in sufficient time.
5. Accounting Records and Supporting Documents
Maintaining accurate financial records is an important part of Corporate Tax compliance.
Businesses should retain records and documents that support the information reported in their Corporate Tax Return, including relevant accounting information and supporting documentation.
Under the Corporate Tax requirements, relevant records and documents should generally be retained for at least seven years following the end of the Tax Period to which they relate.
6. Business Expenses and Taxable Income
Not every business expense is automatically deductible when calculating taxable income.
In principle, legitimate business expenditure incurred for the purpose of deriving taxable income may be deductible, subject to the Corporate Tax Law and applicable limitations.
Certain expenses may be partly deductible, restricted or non-deductible. Businesses should therefore maintain clear supporting records and correctly classify business and personal expenditure.
7. Small Business Relief
Eligible UAE businesses should also consider whether Small Business Relief may apply.
Under the current rules, eligible Resident Taxable Persons with revenue not exceeding AED 3 million may be able to elect for Small Business Relief, subject to the applicable conditions.
In August 2026, the UAE Ministry of Finance announced an extension allowing the AED 3 million threshold to continue to apply for relevant Tax Periods ending on or before 31 December 2029.
Small Business Relief is subject to specific eligibility requirements and should not be assumed to apply solely because a business has revenue below the threshold.
