How UAE Corporate Tax Return Filing Actually Works (2026 Update)

UAE corporate tax return filing is how a business reports taxable income to the Federal Tax Authority for each financial year. Every registered taxable person files one return per tax period, generally within nine months of the year-end, even at 0%. Corporate tax is 9% on profit above AED 375,000 and 0% below.

Key takeaways

• Everyone registered files. A corporate tax return is required for each tax period even if your profit is below AED 375,000 and your tax is nil.
• The rate is simple. 0% on the first AED 375,000 of taxable income and 9% on the excess.
• Deadline is tied to your year-end. The return and any payment are generally due within nine months of the end of your financial year.
• Small Business Relief is temporary. It applies to eligible businesses (revenue up to AED 3 million) for tax periods ending on or before 31 December 2026.
• Free zones are not automatic. 0% on qualifying income only applies if you meet the Qualifying Free Zone Person conditions, and you still file a return.

Who must register and file a UAE corporate tax return?

UAE Corporate Tax applies to "taxable persons", which broadly covers UAE-incorporated companies, foreign companies effectively managed and controlled in the UAE, and individuals carrying on a business or business activity in the country above the relevant turnover test. Free zone entities are included too, even where they ultimately pay 0% on qualifying income.

Registration comes first. A business registers with the FTA and receives a Corporate Tax registration number, and then files a return for each tax period. The important point that catches many owners out is that registration and filing are separate from paying tax. You can owe nothing and still have a legal obligation to file. If you are also trading for VAT purposes, that is a distinct registration handled separately — our guide to UAE VAT registration for businesses explains where the two regimes overlap.

How does UAE corporate tax return filing work at 9%?

The headline structure is deliberately straightforward. Taxable income up to AED 375,000 is taxed at 0%, and taxable income above that is taxed at 9%. There is no separate lower band beyond the AED 375,000 relief, so a business with AED 500,000 of taxable profit pays 9% only on the AED 125,000 above the threshold.

You can estimate your position before you file using our UAE corporate tax calculator, which applies the 0% band and the 9% rate to a profit figure you enter. Treat any calculator output as an estimate for planning; the number that matters is the taxable income figure that flows from properly prepared accounts.

How is taxable income worked out?

UAE Corporate Tax starts from the accounting net profit shown in financial statements prepared under acceptable accounting standards, then applies adjustments set out in the Corporate Tax Law. In practice, the return is not simply "profit times 9%". Common adjustments include:

• Adding back expenses that are not deductible, or only partly deductible, for tax purposes.
• Removing income that is exempt, such as certain dividends and qualifying participation income.
• Applying specific rules for interest deductibility, entertainment and related-party transactions.
• Considering transfer pricing where you transact with related parties or connected persons, with arm's-length pricing and, for larger groups, documentation.

Because these adjustments determine the final tax, accurate bookkeeping through the year is what makes filing painless. Clean, reconciled accounts turn the return into a data-entry exercise rather than a year-end scramble.

When is the UAE corporate tax return due?

The corporate tax return is generally due within nine months of the end of the relevant financial year, and any tax payable is due by the same date, though you should confirm your exact filing date against your FTA account, as it turns on your financial year-end. For a company with a financial year ending 31 December 2025, that points to a filing and payment date of 30 September 2026.

There is one filing per tax period — the UAE does not use provisional or advance corporate tax returns the way some countries do — so the nine-month window is the deadline to plan around. Late registration, late filing and late payment each carry FTA administrative penalties, so building the deadline into your compliance calendar early is the single most effective way to avoid cost. If you would like a professional to hold that timeline for you, book a consultation and we will map your exact dates.

What is Small Business Relief and how long does it last?

Small Business Relief lets an eligible resident business elect to be treated as having no taxable income for a tax period, which effectively removes the corporate tax charge and simplifies compliance for that period. To qualify, revenue must not exceed AED 3 million in the relevant and previous tax periods, and the business must make the election in its return.

The key planning point is timing. The relief applies to tax periods ending on or before 31 December 2026, and no extension has been announced. Businesses that have leaned on Small Business Relief should model what their position looks like once it sunsets, because the same revenue that qualified for relief may sit within the 9% regime in the following period.

How are free zone companies treated?

Free zone businesses sit under the same corporate tax law, but a Qualifying Free Zone Person (QFZP) can benefit from 0% on its qualifying income. That status is conditional, not automatic. Broadly, a QFZP must earn qualifying income, maintain adequate substance in the UAE, meet de minimis limits on non-qualifying revenue, comply with transfer pricing rules and not have elected to be taxed at the standard rate.

Get any of those conditions wrong and the entity can lose QFZP status, with standard corporate tax applying. Free zone companies still register and file an annual return regardless of the 0% outcome. Because the qualifying-income analysis is technical and fact-specific, it is worth reading our detailed explainer on UAE corporate tax for free zone companies and getting the position reviewed before you rely on 0%.

What about very large multinational groups?

Most UAE businesses are fully covered by the 0% / 9% framework above. Separately, very large multinational groups with consolidated global revenue of at least EUR 750 million may fall within a domestic minimum top-up tax of 15% under the global minimum tax rules. This is a narrow, group-level regime that does not change the ordinary 9% analysis for a standalone UAE company, and groups of that size should take dedicated advice.

Getting your filing right

UAE corporate tax return filing rewards preparation. Keep your accounts reconciled through the year, confirm your exact deadline early, decide on any elections such as Small Business Relief deliberately, and pressure-test free zone status before assuming 0%. Every return we prepare is reviewed and signed off by a licensed, FTA-registered tax agent, so the figures that reach the FTA have had professional eyes on them.

For official guidance, see the FTA's Corporate Tax pages and the Ministry of Finance's Corporate Tax resources. If you would rather hand the whole process to a specialist, book a consultation and we will take it from registration through to a signed, filed return.

Frequently asked questions

Do I still file a UAE corporate tax return if my profit is below AED 375,000?

Yes. The 0% band lowers your tax bill to nil, but every registered taxable person must still submit a return for each tax period. Being below the threshold is not an exemption from filing, and a missed return can trigger administrative penalties even when no tax is due.

How long do I have to file after my financial year ends?

The return is generally due within nine months of the end of the relevant financial year, and any tax owed is payable by the same date. A company with a 31 December year-end would file by 30 September of the following year. Always confirm your exact due date against your FTA account, because it is fixed to your specific tax period.

Is Small Business Relief permanent?

No. Small Business Relief currently applies to tax periods ending on or before 31 December 2026 for businesses with revenue at or below AED 3 million that elect for it. No extension has been announced beyond that date, so businesses relying on it should plan for a possible return to standard corporate tax treatment afterwards.

Does my free zone company pay 0% automatically?

Not automatically. A free zone entity must meet the Qualifying Free Zone Person conditions, including qualifying income, adequate substance and de minimis limits, to benefit from 0% on qualifying income. If those conditions fail, standard corporate tax rates can apply. Free zone status still requires registration and an annual return.

What happens if I register or file late?

The FTA applies administrative penalties for late registration, late filing and late payment. Penalties escalate the longer an obligation is outstanding, so the practical priority is to register on time, keep proper records, and file even when the tax due is nil.

Do I need audited financial statements to file?

It depends on your revenue and structure. Some taxable persons, including certain larger businesses and qualifying free zone persons, are required to prepare audited financial statements, while smaller businesses may not be. A licensed professional can confirm whether the audit requirement applies to your entity.
