If your company has a financial year ending in 2025 or 2026, you are about to file your first UAE corporate tax return. For many business owners, this is entirely new territory. The UAE only introduced corporate tax in June 2023, and the first returns for most companies became due in late 2025 or are due in 2026.
The process is handled entirely online through the Federal Tax Authority's EmaraTax portal. It is not complicated if you prepare properly, but the penalties for getting it wrong or filing late are real and escalate quickly.
This guide walks you through the complete process: what you need before you start, how to file step by step on EmaraTax, how to claim Small Business Relief if you qualify, and how to avoid the mistakes that trigger fines.
Your Filing Deadline
UAE corporate tax returns must be filed within nine months after the end of your company's financial year. The deadline for filing and the deadline for paying any tax owed are the same date.
Deadlines by Financial Year End
Here are the filing deadlines that apply to most UAE businesses right now.
| Financial Year End | Filing and Payment Deadline |
|---|---|
| June 30, 2025 | March 31, 2026 |
| September 30, 2025 | June 30, 2026 |
| December 31, 2025 | September 30, 2026 |
| March 31, 2026 | December 31, 2026 |
| June 30, 2026 | March 31, 2027 |
| December 31, 2026 | September 30, 2027 |
Most UAE companies follow a calendar financial year ending December 31. If that is you, your first return was due September 30, 2025 (for FY 2024), and your next return is due September 30, 2026 (for FY 2025).
What Happens If You Miss the Deadline
The Federal Tax Authority does not offer grace periods. Even a single day past the deadline counts as a full month late. The penalty structure is straightforward but painful.
Late filing costs AED 500 per month for the first 12 months, then AED 1,000 per month from month 13 onward. These penalties apply even if your corporate tax liability is zero. Filing a nil return late still triggers the full penalty.
Late payment of any tax owed attracts interest at 14% per annum on the outstanding amount. There is no cap on total interest. It accrues from the day after your deadline until full payment.
If you have not yet registered for corporate tax, the registration penalty is AED 10,000. However, Cabinet Decision No. 10 of 2024 provides a one-time waiver if you file your first return within seven months of your year end, which is stricter than the standard nine-month deadline (Source: Federal Tax Authority).
What You Need Before You Start
Do not log into EmaraTax until you have these items ready. Missing documents halfway through the process is the most common reason people abandon a filing and come back late.
Financial Statements
You need a complete set of financial statements prepared under International Financial Reporting Standards (IFRS) or IFRS for SMEs. This means a profit and loss statement (income statement), a balance sheet (statement of financial position), a cash flow statement, and notes to the financial statements including related party disclosures and accounting policies.
If your revenue exceeds AED 50 million, your financial statements must be audited by a UAE-licensed audit firm. If your revenue is below AED 50 million, reviewed or compiled statements are acceptable for mainland companies. However, if you are a free zone company claiming Qualifying Free Zone Person (QFZP) status, audited financial statements are now mandatory regardless of revenue, following changes effective for tax periods starting January 1, 2025.
Tax Calculations
Before filing, calculate your taxable income by starting with your accounting profit and making the required adjustments. This includes adding back non-deductible expenses such as fines, penalties, and 50% of entertainment costs. You also need to subtract exempt income including qualifying dividends and certain capital gains. If you have transactions with related parties or connected persons, you need to apply transfer pricing adjustments and prepare the disclosure form. If you have tax losses from a prior period, calculate how much you can carry forward, up to a maximum offset of 75% of current year taxable income.
Your Corporate Tax Registration Number
You need your Corporate Tax Registration Number (TRN), which is different from your VAT TRN if you are VAT registered. If you registered for corporate tax through EmaraTax, your TRN was issued in your registration confirmation. If you have not registered yet, you must do so before you can file. Registration is mandatory for all businesses, even those expecting zero tax liability.
Transfer Pricing Documentation
If your business has transactions with related parties or connected persons, you must complete the Transfer Pricing Disclosure Form as part of your return. This includes transactions between your company and its shareholders, directors, sister companies, or any person where one controls the other. The connected person disclosure threshold is AED 500,000 in aggregate transactions. If you elected Small Business Relief, transfer pricing documentation requirements are waived, though the arm's length principle still applies.
How to File on EmaraTax: Step by Step
EmaraTax is the Federal Tax Authority's online portal for all tax filings. Here is the process from login to submission.
Step 1: Log In to EmaraTax
Go to eservices.tax.gov.ae and sign in using your registered email and password, or authenticate through UAE Pass. Once logged in, navigate to the Corporate Tax section from your dashboard.
Step 2: Select Your Tax Period
The portal will display your registered tax periods. Select the financial year you are filing for. Make sure the dates match your company's fiscal year as registered with the FTA. If the dates are wrong, you need to contact the FTA to correct them before proceeding.
Step 3: Confirm Your Filing Basis
Confirm your accounting basis (accrual or cash, if eligible) and your election status. This is where you indicate whether you are claiming Small Business Relief or QFZP status.
Step 4: Enter Your Financial Data
Enter your revenue, costs, and profit figures from your financial statements. The form will guide you through adjusted taxable income calculations. Key sections include total revenue and cost of goods sold, operating expenses and other deductions, exempt income to be subtracted, non-deductible expenses to be added back, and prior year tax losses to be applied (up to 75% of current year taxable income).
Step 5: Complete the Transfer Pricing Disclosure
If you have related party or connected person transactions, complete the Transfer Pricing Disclosure Form. Declare each transaction category (services, goods, financing, IP), the aggregate value, and the pricing methodology you applied. Even if you believe all transactions are at arm's length, you must still disclose them. If you have no related party transactions, you can skip this section.
Step 6: Upload Supporting Documents
Upload your financial statements and any supporting schedules. The portal accepts PDF format. Make sure your files are clearly named and correspond to the correct tax period.
Step 7: Review and Submit
Review your complete return summary. Double check every number against your financial statements. Once satisfied, submit the return. You will receive a confirmation with a reference number. Save this confirmation.
Step 8: Pay Any Tax Due
If your return shows a tax liability, pay through EmaraTax via GIBAN bank transfer or credit card by the same nine-month deadline. When using GIBAN, use the exact reference number provided to ensure your payment is matched to your filing. Late payment triggers the 14% annual interest charge.
How to Claim Small Business Relief
Small Business Relief is a temporary measure that lets qualifying businesses elect zero taxable income. It is available through December 31, 2026 tax periods only (Source: Federal Tax Authority).
Who Qualifies
To claim Small Business Relief, your business must be a UAE resident person (natural or juridical), your revenue must be AED 3 million or less in the current tax period and in every previous tax period, you must not be a Qualifying Free Zone Person, and you must not be part of a multinational enterprise group with consolidated revenue above AED 3.15 billion.
The historical revenue requirement is critical. If your revenue exceeded AED 3 million in any prior tax period, you permanently lose eligibility for Small Business Relief, even if your current revenue has dropped below the threshold.
How to Elect It
Small Business Relief is not automatic. You must actively elect it on your corporate tax return for each tax period. There is no separate application form and no advance approval from the FTA. In the return, you declare that your revenue did not exceed AED 3 million, confirm you meet all eligibility criteria, and check the election box.
What It Means for Your Filing
When you elect Small Business Relief, your taxable income is treated as zero and your corporate tax liability is nil. You can file a simplified return rather than a full return. Transfer pricing documentation requirements are waived, though the arm's length principle still applies to your transactions. You may also use cash basis accounting if eligible.
You still must file the return by the deadline. Electing Small Business Relief does not exempt you from the filing obligation, and late filing penalties still apply to nil returns.
Filing as a Free Zone Company
Free zone companies have additional considerations when filing their corporate tax return.
Claiming QFZP Status
If your free zone company qualifies as a Qualifying Free Zone Person, you pay 0% corporate tax on qualifying income and 9% on non-qualifying income. To claim this status, you must elect it on your corporate tax return. You need audited financial statements regardless of your revenue. This is a change from previous rules where audits were only required above AED 50 million. For tax periods starting January 1, 2025, all QFZPs must have audited special-purpose financial statements.
The De Minimis Rule
If your non-qualifying revenue exceeds the lower of 5% of total revenue or AED 5 million, you lose QFZP status entirely for that tax period. All your income then becomes taxable at 9%. This makes accurate income classification essential before you file.
Audit Costs
For a small trading company with turnover under AED 3 million, a QFZP-compliant audit typically costs AED 5,000 to AED 12,000. Mid-sized companies with AED 3 million to AED 15 million turnover usually pay AED 12,000 to AED 30,000. Budget for this cost when planning your year end process.
Common Filing Mistakes and How to Avoid Them
These are the errors the FTA sees most often from first-time filers.
Missing the Deadline by Even One Day
The penalty clock starts immediately. One day late counts as one full month. If you are not ready by the deadline, file what you have and amend later. A filed return with minor errors is better than no return at all. Voluntary disclosure of errors before an FTA audit attracts a fixed AED 500 penalty, while errors discovered during an audit trigger a 15% penalty on underpaid tax plus 1% monthly interest.
Not Filing Because You Owe Zero Tax
Many business owners assume that if they owe no tax, they do not need to file. This is wrong. Every registered business must file a return regardless of profit or loss. The AED 500 per month penalty applies equally to nil returns filed late.
Misclassifying Exempt Income
Not all income a business receives is taxable, but the exemptions have specific conditions. Qualifying dividends and capital gains from qualifying participations are exempt, but you must meet the participation exemption requirements. If you claim income as exempt when it does not qualify, you face underpayment penalties plus interest.
Forgetting the Transfer Pricing Disclosure
If you have any transactions with related parties or connected persons above AED 500,000 in aggregate and you do not complete the Transfer Pricing Disclosure Form, your return is considered incomplete. This includes salary payments to shareholder-directors, management fees between related companies, and loans between connected persons. Many small business owners who pay themselves a salary through their company are caught by this requirement.
Using Unaudited Statements When an Audit Is Required
If your revenue exceeds AED 50 million, or if you are claiming QFZP status in a free zone, you must have audited financial statements. Filing with unaudited statements when an audit is required can invalidate your return and trigger penalties. Start the audit process early because UAE-licensed audit firms are heavily booked during peak filing season.
Failing to Elect Small Business Relief
If you qualify for Small Business Relief but forget to elect it on your return, you file a standard return and calculate your tax normally. The election cannot be made retroactively after submission. If you think you qualify, make the election before you submit.
The Penalty Summary
Here is a complete breakdown of the penalties you could face.
| Violation | Penalty Amount |
|---|---|
| Late registration | AED 10,000 (waived if first return filed within 7 months of year end) |
| Late filing (months 1 to 12) | AED 500 per month |
| Late filing (month 13 onward) | AED 1,000 per month |
| Late payment | 14% annual interest on unpaid tax, no cap |
| Incorrect return (self-corrected before deadline) | AED 500 fixed |
| Voluntary disclosure after deadline | 1% per month of underpaid tax |
| Error found during FTA audit | 15% of underpaid tax plus 1% monthly interest |
| Failure to maintain records | AED 10,000 (AED 20,000 if repeated) |
| Failure to cooperate with audit | AED 20,000 |
These penalties are governed by Cabinet Decision No. 75 of 2023, with updates under Cabinet Decision No. 129 of 2025 effective April 14, 2026 (Source: Federal Tax Authority).
What to Do After Filing
Filing your return is not the end of your compliance obligations for the year.
Keep Your Records
The FTA requires you to retain all financial records, supporting documents, and tax calculations for a minimum of seven years. This includes bank statements, invoices, contracts, payroll records, and any correspondence related to your tax position. Store digital copies securely because the FTA can request them during an audit at any time within the retention period.
Mark Next Year's Deadline
Set a reminder at least three months before your next filing deadline. This gives you time to close your books, prepare financial statements, get an audit if required, and calculate your taxable income without rushing. Starting the process in the final weeks before the deadline is how mistakes happen.
Monitor for FTA Updates
The UAE corporate tax framework is still evolving. The FTA regularly issues public clarifications, new guides, and updates to the EmaraTax portal. Cabinet Decision No. 129 of 2025, effective April 14, 2026, introduced significant changes to the penalty regime and voluntary disclosure process. Stay current by checking the FTA website and reviewing any notifications in your EmaraTax dashboard.
