The UAE's corporate tax regime is no longer new territory – but for thousands of businesses, it is still unfinished business. Since Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses came into force, the Federal Tax Authority has been steadily tightening the compliance net. Registration deadlines have passed. Penalties have been issued. And a limited waiver window – one that could save you AED 10,000 – is now actively running. If your business has not yet registered, or if you registered late and want to recover your fine, this is what you need to know.

The stakes here are straightforward. Under UAE law, every taxable person – whether a mainland company, a free zone entity, a foreign company with a UAE presence, or an individual doing business here – must register for corporate tax with the FTA. There is no revenue threshold that lets you skip registration. Even a dormant company or a newly incorporated entity with zero taxable income must get a Corporate Tax Registration Number (CTRN) through the EmaraTax portal. Failure to register on time carries a fixed administrative penalty of AED 10,000 under Cabinet Resolution No. (10) of 2024.

All resident juridical persons (mainland LLCs, free zone companies, joint stock companies, branches of foreign companies registered in the UAE), non-resident juridical persons with a Permanent Establishment (PE) or a nexus in the UAE, and natural persons (sole traders, individual business owners, freelancers) whose annual business turnover exceeds AED 1 million in any Gregorian calendar year from 2024 onwards must register.

Two things worth highlighting. First, free zone companies are not exempt from registration – even Qualifying Free Zone Persons (QFZPs) who benefit from the 0% tax rate must register and file annually. Missing registration can immediately put your QFZP status at risk and expose you to the 9% rate for the current and the following four tax periods. Second, if you are already VAT-registered, that does not cover you for corporate tax. The FTA issues a separate Tax Registration Number (CTRN) for corporate tax – you must apply again through EmaraTax.

For resident juridical persons incorporated on or after 1 March 2024, the deadline is three months from the date of incorporation, establishment, or recognition in the UAE.

Under FTA Decision No. 3 of 2024, registration deadlines for resident juridical persons incorporated before 1 March 2024 are tied to the month of trade licence issuance, regardless of the year. The table below shows the full schedule. Where a business holds multiple licences, the earliest issuance date governs. Where a licence was expired at 1 March 2024, the original issuance month is still used. (See also the Corporate Tax Registration Deadline guide for a quick-reference summary.)

Non-resident entities with a Place of Effective Management (POEM) in the UAE are treated as resident persons and follow the resident juridical person deadlines above.

The FTA launched a formal penalty waiver initiative, backed by a Cabinet Decision, giving late registrants a genuine path to avoid or recover the fine – provided they move quickly. The waiver initiative, effective 14 April 2025, is retroactive to penalties incurred from 1 June 2023. It applies to all corporate taxpayers and certain exempt persons who either missed the registration deadline or registered late and received the AED 10,000 fine under Cabinet Resolution No. (10) of 2024. As of July 2025, the FTA confirmed that over 33,900 businesses had already benefited from the waiver initiative – but many more remain unregistered.

The condition is a single, clear rule: file your first corporate tax return (or annual declaration, if you are an exempt entity) within seven months from the end of your first tax period.

One important note: the FTA's EmaraTax portal has a built-in eligibility tool that lets you check your specific waiver deadline by entering your incorporation date and tax period. Use it before acting – the calculation depends on your exact financial year-end, not a generic date.

Registration is done online through the EmaraTax portal at emaratax.gov.ae. Login via UAE PASS is now the primary access method.

Registration is only the first step. Once registered, you are obligated to maintain proper accounting records in line with IFRS for a minimum of seven years; file an annual corporate tax return via EmaraTax within nine months of your financial year-end; pay any corporate tax liability at the same time as filing – there are no advance or provisional payment requirements; and keep financial records and supporting documentation available for potential FTA inspection.

For businesses with annual revenue exceeding AED 50 million, and for all Qualifying Free Zone Persons regardless of revenue, audited financial statements are mandatory.

The corporate tax registration framework rests on several key instruments.

The primary corporate tax law, effective for tax periods starting on or after 1 June 2023, establishes the obligation for all taxable persons to register with the FTA.

Effective 1 March 2024 – sets the specific registration timelines for both resident and non-resident juridical persons and natural persons. For existing resident juridical persons, deadlines are tied to the month of trade licence issuance. New entities incorporated on or after 1 March 2024 must register within three months of incorporation. Natural persons whose annual business turnover exceeds AED 1 million must register by 31 March of the following Gregorian calendar year.

Effective 1 March 2024 – amends the schedule of violations and administrative penalties in Cabinet Decision No. 75 of 2023, which governs penalties for violations of Federal Decree-Law No. 47 of 2022. Cabinet Resolution No. (10) of 2024 introduced the specific AED 10,000 administrative penalty for late submission of a corporate tax registration application, aligning it with equivalent penalties for late VAT and Excise Tax registration. The original Cabinet Decision No. 75 of 2023 had set the late registration penalty at AED 20,000; Cabinet Resolution No. (10) of 2024 reduced this to AED 10,000.

The FTA is authorised to waive or refund the AED 10,000 late registration penalty where the taxpayer files their first corporate tax return within seven months of the end of their first tax period. The initiative is retrospective to penalties incurred from 1 June 2023, and applies whether the penalty has been issued, paid, or not yet imposed.

Effective 1 January 2026 – amends the Tax Procedures Law. Key changes include: a fixed five-year window to claim tax credit refunds; and a new voluntary disclosure framework allowing taxpayers to correct errors within two years of filing a refund request, provided the FTA has not yet issued a decision.
