Corporate tax registration and Small Business Relief in the UAE

The short version

If you run a business in the UAE, mainland or free zone, you are very likely in scope for Corporate Tax, even if you expect to owe nothing. Registration is a separate step from filing, has its own deadline tied to when your trade licence was issued, and missing it can breach the law even if your business qualifies for relief.

Registration is not optional, even if you expect to owe nothing

UAE Corporate Tax applies to most businesses operating in the UAE. Separately from whether you end up owing tax, the Federal Tax Authority (FTA) requires eligible businesses to register for Corporate Tax and obtain a Tax Registration Number. The FTA's decision setting registration deadlines for taxpayers took effect on 1 March 2024.

The UAE Government Portal (u.ae) confirms one worked example directly: a business whose trade licence was issued in January or February had to register by 31 May 2024. For the fuller picture, two independent professional-services firms, PwC and Deloitte, separately published the same month-by-month schedule in their summaries of FTA Decision No. 3 of 2024, for resident juridical persons whose licence was issued before 1 March 2024:

Where a business holds more than one UAE trade licence, the earliest issuance date applies. These deadlines were set for the first implementation year; a business newly formed after March 2024 follows its own deadline tied to its own incorporation or licence date, so check your specific deadline on EmaraTax rather than matching yourself to this table by month alone.

Small Business Relief: who can elect it

Separately from registration, a resident taxable person with modest revenue can elect Small Business Relief, treating their income as having no taxable Corporate Tax liability for that period. Under Ministerial Decision No. 73 of 2023:

• Revenue threshold: revenue must be AED 3,000,000 or less in both the current tax period and every previous tax period in which the relief is claimed. If revenue exceeds that figure in either period, the relief is not available for that period.
• Applicable period: the relief applies to tax periods starting on or after 1 June 2023 and ending on or before 31 December 2029. The end date was extended from an original cutoff of 31 December 2026 by Ministerial Decision No. (131), announced 7 August 2026.
• Who is excluded: Qualifying Free Zone Persons (businesses that have elected into the free zone Corporate Tax regime under Article 18 of the Corporate Tax Law), non-resident taxpayers (including UAE branches of foreign companies), and members of a multinational group whose consolidated group revenue exceeds AED 3.15 billion.
• It is an election, not automatic: a qualifying business applies for the relief; it does not apply itself, and a business can choose not to take it.

What happens if you miss the registration deadline

The u.ae blog post states plainly that missing the registration deadline risks breaching UAE tax legislation, without naming a specific penalty amount on that page. The Ministry of Finance's own website (mof.gov.ae) confirms the figure directly: AED 10,000 for failing to register for Corporate Tax by the applicable deadline, under Cabinet Decision No. 10 of 2024, which amended the penalty schedule originally set by Cabinet Decision No. 75 of 2023, effective 1 March 2024. This resolves what earlier secondary reporting (PwC, Deloitte, Crowe) described without agreeing on a decision number.

The practical takeaway

Treat Corporate Tax registration as a deadline tied to your own trade licence, not a single UAE-wide date, and treat it as separate from whether you expect to owe anything. If your revenue is modest, Small Business Relief may mean no tax is actually due, but it does not excuse you from registering, and registering late carries a stated AED 10,000 administrative penalty, independent of whether any tax is ultimately owed, though the FTA has confirmed a waiver for taxpayers who file their first return within 7 months of their first tax period's end. When in doubt, check your specific deadline and status directly on EmaraTax rather than relying on a generic schedule.
