## What is the corporate tax filing deadline UAE businesses must meet?

The corporate tax filing deadline UAE businesses must meet is 9 months after the end of their financial year. This rule comes from Federal Decree-Law 47 of 2022. The same 9-month window covers both filing the corporate tax return and paying any tax due to the Federal Tax Authority (FTA).

This single deadline applies to every taxable person registered for UAE corporate tax, including mainland companies, free zone entities, and qualifying free zone persons (QFZPs). Your exact date depends on when your financial year ends. For a primer on the wider regime, see our [UAE Corporate Tax](https://einvoicedirect.ae/uae-corporate-tax) hub.

## How the 9 months filing deadline works

The 9 months filing deadline starts the day after your financial year closes. If your books close on December 31, the clock starts January 1 and ends on September 30 of the following year. There is no extension for weekends or public holidays in the law, so plan to file a few days early.

The same date applies to:

- Submitting the corporate tax return through the EmaraTax portal.
- Paying the corporate tax balance owed for the period.
- Filing any disclosure schedules required for transfer pricing.

### Why the UAE uses a single 9-month window

Many tax systems separate filing and payment dates. The UAE chose one combined deadline to simplify compliance for small and mid-sized businesses. It also gives finance teams enough time to close books, prepare audited financial statements where required, and reconcile VAT positions before the corporate tax return is locked in.

## Corporate tax due date UAE: deadlines by financial year end

The table below shows the corporate tax due date UAE companies face for the most common financial year ends. The dates assume a 12-month tax period.

| Financial year end | First taxable period starts | Filing and payment due |
| --- | --- | --- |
| 31 December 2024 | 1 January 2024 | 30 September 2025 |
| 31 March 2025 | 1 April 2024 | 31 December 2025 |
| 30 June 2025 | 1 July 2024 | 31 March 2026 |
| 30 September 2025 | 1 October 2024 | 30 June 2026 |
| 31 December 2025 | 1 January 2025 | 30 September 2026 |
| 31 March 2026 | 1 April 2025 | 31 December 2026 |

### First tax period quirks

The corporate tax law applies to financial years starting on or after 1 June 2023. That created some unusual first periods.

- A company with a financial year of 1 June 2023 to 31 May 2024 had a first return due by 28 February 2025.
- A company with a calendar year had its first return cover 1 January 2024 to 31 December 2024, due 30 September 2025.
- Short first periods, for example a newly incorporated entity, still get 9 months after their first year end. A short period does not shorten the deadline.

The FTA also issued a one-time extension under Decision 7 of 2024 for certain short first periods ending on or before 29 February 2024, pushing those deadlines to 31 December 2024. That relief was period-specific and does not apply to later year ends.

## UAE corporate tax return deadline: what to file

The UAE corporate tax return deadline applies to a single annual return submitted through EmaraTax. There are no quarterly corporate tax filings in the UAE. The return includes:

- Taxable income calculated from accounting profit with statutory adjustments.
- Application of the 0% rate on the first AED 375,000 of taxable income.
- Application of the 9% rate above AED 375,000.
- Small business relief election, available for revenue up to AED 3,000,000 through 2026.
- Free zone status and QFZP claims, where relevant.
- Transfer pricing disclosure forms above the prescribed thresholds.

### Large multinationals and the DMTT

Multinational groups with consolidated global revenue of EUR 750,000,000 or more became subject to the 15% Domestic Minimum Top-up Tax (DMTT) from January 2025. The 9-month filing window still applies, but these groups face extra Pillar Two disclosures alongside their UAE return.

## Payment timing and how to settle the bill

The tax payment is due on the same date as the return. The FTA does not issue a separate assessment first. You self-assess the liability, file the return, and pay through EmaraTax using GIBAN bank transfer, card, or other supported channels.

### Practical tips for payment

- Initiate bank transfers at least 3 working days before the deadline. Funds must clear the FTA account on or before the due date.
- Keep the payment reference number with your records for reconciliation.
- If your return shows a refund, the FTA processes it after the return is approved, not on the deadline.

## What late filing costs

Missing the corporate tax filing deadline triggers administrative penalties set by Cabinet decisions. Late filing of the corporate tax return attracts a fixed penalty, and unpaid tax accrues monthly percentage-based penalties on the outstanding balance.

Penalties stack quickly when both the return and the payment are late. For the full schedule, read our guide to [late filing penalties](https://einvoicedirect.ae/uae-corporate-tax/late-filing-corporate-tax-penalty-uae).

### Common reasons businesses miss the deadline

- Late completion of audited financial statements.
- Unresolved VAT reconciliations that block the tax computation.
- Errors in EmaraTax registration that delay portal access.
- Transfer pricing documentation gaps for related-party transactions.

## Preparing for the deadline: a 90-day checklist

Most finance teams need at least 90 days to close, compute, and review the corporate tax return. A working timeline looks like this:

- **Months 1 to 3 after year end:** close the books, finalise audited statements where required.
- **Months 4 to 6:** prepare the tax computation, apply free zone tests, finalise transfer pricing files.
- **Months 7 to 8:** internal review, board sign-off, draft return in EmaraTax.
- **Month 9:** submit the return, fund the tax account, file by the due date.

## How corporate tax filing interacts with e-invoicing

From 2027, UAE businesses will also operate under the Peppol 5-corner DCTCE (Decentralized Continuous Transaction Control and Exchange) e-invoicing model in the PINT AE format. Phase 1 mandatory go-live is 1 January 2027 for businesses with revenue of AED 50,000,000 or more, with the ASP appointment deadline set at 30 October 2026. Cleaner invoice data feeds directly into more accurate corporate tax computations and faster year-end closes. The [UAE Corporate Tax](https://einvoicedirect.ae/uae-corporate-tax) framework will increasingly rely on this real-time invoice data.

## Frequently asked questions

### When is the corporate tax filing deadline in the UAE?

The corporate tax return and payment are due 9 months after the end of your financial year. For a calendar year ending 31 December 2025, the deadline is 30 September 2026. The same date applies to filing the return through EmaraTax and paying any tax owed. There is no separate payment date later in the year.

### Does the UAE require quarterly corporate tax filings?

No. The UAE corporate tax system uses a single annual return filed once per financial year. There are no quarterly instalments or advance payments under Federal Decree-Law 47 of 2022. You self-assess the full year's liability, file through EmaraTax, and pay the balance within 9 months of your year end.

### What if my first tax period is shorter than 12 months?

A short first period still gets the full 9-month filing window after its year end. The deadline is not shortened in proportion to the period length. For example, a 7-month first period ending 31 December 2024 still has a return due by 30 September 2025. Plan the close process to fit the shorter accounting period.

### Can I extend the corporate tax due date in the UAE?

The Federal Tax Authority does not offer routine extensions on request. A one-time relief under FTA Decision 7 of 2024 extended certain short first periods to 31 December 2024, but that was period-specific. Plan to file on or before the statutory 9-month deadline. Late filings face administrative penalties and percentage-based charges on unpaid tax.

### What happens if I miss the UAE corporate tax return deadline?

Missing the deadline triggers a fixed penalty for late filing plus monthly percentage penalties on any unpaid tax. Penalties stack until both the return is submitted and the tax is paid in full. The FTA can also issue assessments based on available information. Filing late even by one day starts the penalty clock.

### Do free zone companies follow the same 9-month deadline?

Yes. Free zone entities, including qualifying free zone persons, file under the same 9-month rule. They must submit a UAE corporate tax return even when their qualifying income is taxed at 0%. The return is also where they evidence their QFZP status and report any non-qualifying income taxed at the 9% rate.

### Is the payment date the same as the filing date?

Yes. Filing and payment share the same 9-month deadline. You self-assess the liability on the return and settle it through EmaraTax on or before that date. Initiate bank transfers at least 3 working days early so funds clear the FTA account on time. Late payments accrue percentage-based penalties separate from late filing fines.
