UAE Tax Deadlines 2026: Every Date Every Business Must Know

Quick Answer: UAE tax deadlines 2026 include five critical dates. The new FTA penalty regime under Cabinet Decision No. 129 of 2025 takes effect on 14 April 2026. The corporate tax registration penalty waiver expires on 31 July 2026. Calendar year businesses must file their corporate tax return by 30 September 2026. Natural persons (individuals with business turnover above AED 1 million in 2025) must also register by 31 March 2026 and file by 30 September 2026. VAT returns fall due 28 days after each quarter ends. Missing any deadline triggers FTA penalties starting at AED 500 per month.

What Changes on 14 April 2026 Under Cabinet Decision No. 129 of 2025?

On 14 April 2026, the UAE introduces a unified and significantly reformed tax penalty regime under Cabinet Decision No. 129 of 2025. Published on 10 November 2025, this decision replaces the previous penalty structure for VAT, Excise Tax, and Corporate Tax violations with a simpler and in many cases lower set of charges.

Key changes effective 14 April 2026:

Late payment penalties simplified: The previous complex model is replaced by a single annual percentage rate, making it easier to calculate and manage outstanding amounts.
Arabic recordkeeping fine reduced: The fine for failing to maintain records in Arabic drops from AED 20,000 to AED 5,000.
Change notification fines tiered: Failing to notify the FTA of changes is now AED 1,000 for a first breach and AED 5,000 for repeat violations.
Voluntary disclosure incentives increased: Penalties for self-reported corrections are substantially lower under the new regime, encouraging businesses to come forward rather than wait for an FTA audit.
Proportional approach: Minor administrative errors now attract smaller, proportional fines rather than the previously large fixed amounts.

If you have any open tax disputes or outstanding voluntary disclosures, it is worth acting before 14 April. Read our full guide on what changes on 14 April 2026 and the 8-day action plan to understand every risk category before the deadline.

What Is the UAE Corporate Tax Filing Deadline for 2026?

The corporate tax return filing deadline in the UAE is nine months after the end of a company’s financial year, under Federal Decree-Law No. 47 of 2022. For the vast majority of UAE businesses that use a calendar year (1 January to 31 December), the first corporate tax return deadline is 30 September 2026.

This covers the financial year ending 31 December 2025, which is the first full tax year for most businesses after the corporate tax law took effect on 1 June 2023. If you have not yet registered for corporate tax, do so immediately to avoid the AED 10,000 late registration penalty.

Natural persons (individuals): If you are a UAE resident individual whose business turnover exceeded AED 1 million in the 2025 calendar year, your registration deadline was 31 March 2026 and your filing deadline is 30 September 2026. For the complete rules on when individuals must register and file, see: UAE Corporate Tax for Natural Persons and Individuals 2026.

What you must do by 30 September 2026: File the corporate tax return on EmaraTax AND pay any tax due. The FTA treats filing and payment as a single obligation. Once your return is submitted, pay the tax liability via your GIBAN — see our complete guide: How to Pay UAE Corporate Tax 2026.
Free zone companies: Even businesses benefiting from the 0% Qualifying Free Zone Person rate must still file. The return is mandatory regardless of tax liability.
Small Business Relief: Businesses electing Small Business Relief under Cabinet Decision No. 73 of 2023 must still file and declare the election on EmaraTax.

Penalties for late corporate tax returns are AED 500 per month for the first 12 months after the missed deadline, rising to AED 1,000 per month from the 13th month onward.

It covers the 8-week preparation timeline from gathering records through EmaraTax submission, the documents you will need, and full fee ranges for professional assistance.

When Are UAE VAT Returns Due in 2026?

UAE VAT returns are due 28 days after the end of each tax period. Most businesses file quarterly. If you are not yet VAT-registered, see our UAE VAT Registration 2026 step-by-step guide to check if you are required to register. The four VAT return deadlines for quarterly filers in 2026 are:

28 April 2026: Q1 (January to March 2026)
28 July 2026: Q2 (April to June 2026)
28 October 2026: Q3 (July to September 2026)
28 January 2027: Q4 (October to December 2026)

Monthly filers follow the same 28-day rule but submit every month. For a complete walkthrough of the Form 201 filing process, see our UAE VAT Return Filing 2026 guide. Qaspro Global advises all VAT-registered businesses to file at least five working days before the deadline to avoid EmaraTax system delays near cut-off dates.

The penalty for late VAT return submission is AED 1,000 for the first offence and AED 2,000 for each subsequent late filing within 24 months, under Federal Decree-Law No. 28 of 2022.

Why Is 31 July 2026 Critical for Corporate Tax Registration?

The UAE government introduced a one-time penalty waiver scheme allowing businesses that registered late for corporate tax to have their AED 10,000 registration penalty waived or refunded. This scheme expires on 31 July 2026.

If your business registered for corporate tax after the required deadline and received an AED 10,000 penalty, you can apply to have it removed through EmaraTax before July 31. After that date, the penalty becomes permanent and cannot be reversed through this scheme.

To check whether you have an outstanding registration penalty, log in to EmaraTax, go to your Tax Account, and review the Penalties section. If you see an AED 10,000 charge for late registration, apply for the waiver before July 31.

What Is the UAE E-Invoicing Pilot in July 2026?

The UAE is rolling out a national e-invoicing system based on the Peppol framework. A voluntary pilot for large businesses is expected to begin in July 2026, with mandatory adoption for large businesses from January 2027.

Participation in the July 2026 pilot is optional, but businesses that join early benefit from testing their systems before mandatory compliance kicks in. There are no penalties during the pilot phase.

What Happens to Unused VAT Credits in 2026?

Under Federal Decree-Law No. 16 of 2025, excess input VAT credits expire five years after the end of the relevant tax period. Credits accrued before 2022 face a transitional deadline of 31 December 2026. After that date, any unclaimed input VAT from pre-2022 periods is permanently forfeited and cannot be refunded.

If your business has been carrying forward a VAT credit balance without claiming a refund, check your EmaraTax account now. Any balance linked to tax periods before 2022 must be submitted as a refund application before 31 December 2026.
