UAE corporate tax effective date and rollout timeline

What is the UAE corporate tax effective date?

The UAE corporate tax effective date is 1 June 2023. Federal Decree-Law 47 of 2022 applies to financial years starting on or after that date. A business with a calendar year first became subject to corporate tax on 1 January 2024. A business with a June year-end first became subject on 1 June 2023. The law covers companies, free zone entities, and qualifying natural persons.

This date marks the start of the UAE's federal corporate tax regime. It is the anchor point for every other deadline: registration, first tax period, return filing, and payment. If you run a UAE company, your first tax period depends entirely on your financial year, not on the calendar year. For the wider framework, see our hub on UAE Corporate Tax.

Why 1 June 2023 matters

The UAE published Federal Decree-Law 47 of 2022 in December 2022. The law set a single national effective date so all businesses use the same starting point. Before this, the UAE had no general corporate income tax outside oil, gas, and foreign bank branches.

The effective date does two things. It sets the earliest day a business can fall inside the new regime. It also fixes the start of the first tax period for every company, based on its own financial year. For a deeper look at the statute itself, see UAE Corporate Tax Law.

Effective date vs first tax period

These two terms are often mixed up. The effective date is fixed: 1 June 2023. The first tax period is specific to your business. It is the first full 12-month financial year that begins on or after 1 June 2023.

Why your financial year drives the timeline

The UAE Federal Tax Authority uses your financial year, not the Gregorian calendar, to define each tax period. If you changed your financial year before the effective date, the new year-end applies. Confirm the year-end on your trade licence and audited accounts.

First tax period by financial year

The table below shows when the first tax period starts and ends for common financial year-ends. The filing deadline is 9 months after the period ends.

Use this table as a starting point. Confirm your year-end with your accountant before relying on these dates. For the headline rate structure, see UAE Corporate Tax Rates.

What the effective date means for tax rates

The rate structure under Federal Decree-Law 47 of 2022 has applied since the effective date.

• 0% on taxable income up to AED 375,000.
• 9% on taxable income above AED 375,000.
• 15% Domestic Minimum Top-up Tax (DMTT) for large multinationals with global revenue of EUR 750 million or more, from financial years starting on or after 1 January 2025.

The 0% and 9% bands apply to most resident businesses. The 15% DMTT only affects the largest multinational groups. Read more on UAE Corporate Tax 9 Percent Threshold and UAE Corporate Tax 15 Percent Pillar 2.

Small business relief through 2026

Resident businesses with revenue up to AED 3 million can elect for Small Business Relief. This relief treats taxable income as zero for the period. It is available for tax periods ending on or before 31 December 2026. You still need to register and file a return.

Registration deadlines after the effective date

The UAE Federal Tax Authority issued staggered registration deadlines based on the month of trade licence issuance. Most resident juridical persons had to register during 2024. Natural persons running a business with turnover above AED 1 million in a calendar year must register by 31 March of the following year.

Missing the registration deadline triggers an administrative penalty. Check your status on the EmaraTax portal and confirm with the UAE Federal Tax Authority.

What you need to register

• Valid trade licence and Memorandum of Association.
• Emirates ID and passport copy for owners or authorised signatories.
• Financial year-end as recorded with the licensing authority.
• Contact details and authorised signatory letter.

Filing and payment deadlines

The corporate tax return is due within 9 months after the end of each tax period. Payment of any tax due is also due by the same date. There is no advance payment requirement at present.

If your first tax period is the year ending 31 December 2024, your first return and payment are due by 30 September 2025. Late filing and late payment each carry separate penalties.

Records you must keep

You must keep accounting records and supporting documents for at least 7 years after the end of the tax period. Records include financial statements, invoices, contracts, transfer pricing files, and any documents supporting exemptions or reliefs.

Free zone businesses and the effective date

Free zone companies are inside the corporate tax regime from the same effective date. A Qualifying Free Zone Person (QFZP) can apply a 0% rate on qualifying income, with 9% on non-qualifying income. To stay a QFZP, you must meet substance, audited accounts, and de minimis rules every tax period.

The effective date does not exempt free zone entities from registration or filing. Even a QFZP with only qualifying income must register and file a return. For the full scope, see Who Pays Corporate Tax in UAE.

Penalties for missing deadlines

Cabinet decisions set administrative penalties under the corporate tax law. Common penalties include:

• Late registration: AED 10,000.
• Late filing of the corporate tax return: AED 500 per month for the first 12 months, then AED 1,000 per month.
• Late payment: monthly penalty on the unpaid amount, plus interest under the tax procedures law.
• Failure to keep records: AED 10,000 for a first offence, AED 20,000 for a repeat.

Penalty rules can change. Confirm current amounts on the UAE Ministry of Finance website before relying on them.

How the effective date connects to VAT and e-invoicing

The 5% Value Added Tax (VAT) has applied since 1 January 2018 under Federal Decree-Law 8 of 2017. VAT returns are due within 28 days of the period end. Corporate tax sits on top of VAT, not in place of it.

UAE e-invoicing is also rolling out separately. The model is a Peppol 5-corner Decentralized Continuous Transaction Control and Exchange (DCTCE) using the PINT AE format. Phase 1 go-live is 1 January 2027 for large taxpayers. Accurate e-invoicing data will support corporate tax filings because both rely on the same underlying sales and purchase records.

A short checklist for UAE businesses

1. Confirm your financial year-end on your trade licence.
2. Identify your first tax period using the table above.
3. Register for corporate tax on EmaraTax if you have not already.
4. Decide if you qualify for Small Business Relief or QFZP status.
5. Set a calendar reminder 9 months after each year-end for the return and payment.
6. Keep accounting records for 7 years.
