Corporate Tax Filing UAE 2026: Deadlines, EmaraTax Steps, Penalties

Corporate tax filing in the UAE runs on one simple clock: the return and the payment are both due within nine months of your financial year-end, through EmaraTax. For the thousands of companies whose 2025 financial year ended on 31 December, that clock runs out on 30 September 2026. This guide covers the deadline for every year-end, the filing steps inside EmaraTax, and the exact penalty ladder for missing it. It also covers the elections – Small Business Relief above all – that must be made inside the return itself.

Your filing deadline, by financial year-end

The rule is nine months from the end of the tax period, for both the return and the payment. Applied to common year-ends:

The dates are simple arithmetic on the nine-month rule, not separate announcements – whatever your year-end, add nine months. Filing early is allowed and sensible; the deadline is a ceiling, not a target.

Quick summary: filing UAE corporate tax

• Deadline: return filed and tax paid within nine months of your financial year-end, via EmaraTax.
• Late return: AED 500 for each month or part of one for the first twelve months, then AED 1,000 per month from month thirteen.
• Late payment: 14% per annum, applied monthly on the unpaid amount.
• Everyone files: a return is due even at AED 0 tax – including free zone companies and businesses electing Small Business Relief.
• Elections live in the return: Small Business Relief (revenue AED 3 million or less, periods ending on or before 31 December 2026) is claimed inside the return, not by separate application.
• Paper trail: records kept 7 years; audited financial statements mandatory above AED 50 million revenue and for every Qualifying Free Zone Person.

Who must file – and who only thinks they need not

Every business registered for corporate tax files a return for every tax period. Zero tax due does not remove the obligation. A company under the AED 375,000 profit line files; so does one electing Small Business Relief, and so does a free zone company claiming the 0% qualifying rate. The return is where each of those positions is declared and defended.

Not yet registered? That is the prior step, with its own AED 10,000 late-registration penalty – our corporate tax registration guide covers it. One relief worth knowing: the FTA waives that late-registration penalty where the return is filed within seven months of the end of the first tax period. It is an incentive to file early, not late.

Filing in EmaraTax, step by step

1. Close the books first. Financial statements under IFRS – or IFRS for SMEs where revenue is below AED 50 million – are the base layer. The return starts from accounting income and adjusts it.
2. Log in to EmaraTax and open the Corporate Tax tile against your registered taxable person. Your registration TRN must already exist.
3. Work through the return schedules. Accounting income, then the adjustments: exempt income, disallowed expenses, related-party positions, reliefs and carried-forward losses where they apply.
4. Make your elections. Small Business Relief, where eligible, is ticked inside the return for that period. Skip the box and the relief is not claimed – the FTA does not apply it for you.
5. Review the computed liability. 0% to AED 375,000 of taxable income, 9% above it, exactly as the rate bands work on our corporate tax overview.
6. Submit, then pay. Both sit inside the nine-month window. A filed return with unpaid tax still accrues the 14% late-payment charge, so treat them as one deadline.

The penalty ladder, precisely

The FTA's published position on a late return: an administrative penalty of AED 500 for each month, or part thereof, during the first twelve months, increasing to AED 1,000 for each month, or part thereof, from the thirteenth month onwards. Note the “or part thereof” – one day into a new month bills the full month.

Unpaid tax is charged separately at 14% per annum, applied monthly on the outstanding amount, under the administrative penalties regime of Cabinet Decision No. 75 of 2023 as amended. The two stack: a company that files six months late and pays nine months late owes the filing penalty, the payment charge, and the tax itself. Filing on time with payment on time costs nothing; every other combination compounds.

Small Business Relief is claimed in the return

Businesses with revenue of AED 3 million or less can elect Small Business Relief for tax periods ending on or before 31 December 2026. The electing business is treated as having no taxable income for that period. The election is made inside the return – there is no separate application, and it does not carry over automatically between periods. Two boundaries our overview spells out: the test is revenue, not profit, and crossing AED 3 million in a period removes the election for that period entirely. Electing SBR still means closing the books and filing on time.

Financial statements and the 7-year rule

Under Ministerial Decision No. 84 of 2025, audited financial statements are mandatory for tax periods starting on or after 1 January 2025 where revenue exceeds AED 50 million. Every Qualifying Free Zone Person needs them too, regardless of revenue, as part of keeping the 0% rate. Tax groups prepare audited special-purpose financial statements. Below those lines, unaudited IFRS or IFRS-for-SMEs statements carry the return.

Whatever the audit position, the FTA requires accounting records kept for a minimum of 7 years, and the wider filing calendar – VAT and ESR alongside corporate tax – sits on our tax compliance hub. The return can be examined long after it is filed; the records are what defend it.

Five filing mistakes that cost real money

• Treating “no tax due” as “no return due”. The AED 500 monthly penalty attaches to the missing return, not the missing tax.
• Filing without paying. The 14% per-annum charge runs on the unpaid balance even with the return safely in.
• Missing the SBR tick-box. Eligible revenue does not claim itself; the election lives inside that period's return.
• Discovering the audit requirement in month eight. Above AED 50 million revenue, or as a QFZP, the audit has to be commissioned early enough to finish inside the nine months.
• Confusing registration with filing. Registration gets you the TRN once; filing recurs every period. The AED 10,000 and AED 500-per-month penalties are different fines for different failures.

Frequently Asked Questions

When is the UAE corporate tax filing deadline?

Within nine months of the end of your tax period, for both the return and the payment, filed through EmaraTax. A financial year ending 31 December 2025 must be filed and paid by 30 September 2026; a year ending 30 June 2026 runs to 31 March 2027.

What is the penalty for late corporate tax filing in the UAE?

AED 500 for each month or part of a month for the first twelve months, rising to AED 1,000 per month from the thirteenth month onwards. Late payment of the tax itself is charged separately at 14% per annum, applied monthly on the unpaid amount.

Do I have to file a corporate tax return if I owe no tax?

Yes. Every registered business files for every tax period. Companies under the AED 375,000 profit threshold, businesses electing Small Business Relief, and free zone companies on the 0% qualifying rate all submit returns. The return is where those zero-tax positions are formally claimed.

How do I claim Small Business Relief when filing?

By electing it inside the corporate tax return for that period, where your revenue is AED 3 million or less and the period ends on or before 31 December 2026. There is no separate application, and the election must be repeated in each eligible period's return.

Do I need audited financial statements to file corporate tax?

Only above certain lines. For tax periods starting on or after 1 January 2025, Ministerial Decision No. 84 of 2025 requires audited financial statements where revenue exceeds AED 50 million, and for every Qualifying Free Zone Person regardless of revenue. Tax groups prepare audited special-purpose statements. Other businesses file on unaudited IFRS or IFRS-for-SMEs accounts, and everyone keeps records for 7 years.

Can the late registration penalty be waived?

Yes, under an FTA initiative: the AED 10,000 late-registration penalty is waived where the taxable person submits its corporate tax return within seven months of the end of its first tax period. It rewards filing early – it does not extend the filing deadline itself.
