A UAE trade license is the first deadline a new company faces, not the last. Under FTA Decision No. 3 of 2024, a company incorporated on or after March 1, 2024 has three months to register for corporate tax — miss it, and the penalty is AED 10,000. Bestax Chartered Accountants walks through the deadline, the penalty waiver that closed earlier this year, and the compliance obligations heading into 2027.
Most founders focus entirely on the license itself. The bigger risk usually shows up afterward, in the tax and filing deadlines nobody flagged until the penalty notice arrives.
Quick Answer: New UAE companies must register for corporate tax within three months of incorporation under FTA Decision No. 3 of 2024. Missing this deadline triggers a AED 10,000 penalty under Cabinet Decision No. 75 of 2023. The FTA’s one-time waiver on this penalty closed on July 31, 2026 — companies that missed registration and didn’t file within that window now carry the penalty permanently, with no current route to reverse it.
Corporate Tax Registration Deadline UAE: What Companies Must Know Heading Into 2027
The Three-Month Window Founders Miss
FTA Decision No. 3 of 2024 sets the registration clock running from the date of incorporation, not the date trading begins. A company incorporated in late 2026, for example, must register within three months of that date — regardless of whether it has issued an invoice yet.
Missing that window costs AED 10,000 under Cabinet Decision No. 75 of 2023 as amended. This is a fixed, one-time fine, separate from any later late-filing or late-payment penalties, and it applies whether the company ultimately owes any tax or not.
The 2025 Penalty Waiver Has Now Closed
In April 2025, the FTA introduced a one-time waiver that could cancel the AED 10,000 penalty for late registrations dating back to June 1, 2023. To qualify, a company needed to file its first corporate tax return — or annual declaration, for exempt persons — within 7 months of its first tax period’s end, rather than the usual 9 months.
That window closed on July 31, 2026. Companies that missed their registration deadline and did not file inside the 7-month window before that date no longer have a route to reverse the penalty — it is now treated as permanent. For any company still working through a late registration, the practical takeaway going forward is that the standard 9-month filing deadline is what applies, with no waiver currently available to offset a late-registration penalty already incurred.
What Follows the Deadline: Ongoing Obligations Into 2027
Corporate tax registration is the first of several recurring obligations a company picks up in its first year, not the only one:
| Obligation | Trigger / Timing |
|---|---|
| Corporate tax registration | Within 3 months of incorporation |
| First corporate tax return | Within 9 months of financial year end (the 7-month waiver window closed July 31, 2026) |
| VAT registration UAE threshold | Once taxable supplies pass AED 375,000 in 12 months |
| Pre-2022 VAT credit refund claims | Must be claimed by December 31, 2026, or forfeited |
| Trade license renewal | Annually, tied to Ejari tenancy and visas |
A late license renewal blocks visa renewals until the license is active again — tracking the license date, visa dates and tax dates as one connected timeline is what prevents that chain reaction.
How Mainland and Free Zone Compare on Tax, Not Just License Cost
Most founders compare mainland and free zone on license price alone. The sharper comparison is what the structure will actually cost in tax once it’s running, because a free zone’s 0% corporate tax rate applies only to qualifying income — and sales to mainland customers generally don’t qualify.
Take a consultancy earning AED 600,000 in profit, almost all from Dubai mainland clients. As a mainland LLC, it pays 9% on the profit above AED 375,000 under the UAE Corporate Tax Law, which comes to AED 20,250.
The same consultancy set up in a free zone fails the qualifying income test, falls under the standard regime, and pays the identical AED 20,250 — but with the trading limits a mainland company doesn’t carry. For a founder in that position, the mainland free zone tax comparison often comes out a wash on tax, which makes the trading flexibility the deciding factor rather than the rate itself. For a full breakdown of the mainland formation process itself, including licensing steps and ownership rules, see our guide to mainland business setup in Dubai.
When a Free Zone Company Needs a Mainland Presence Too
Some structures need both. Dubai Executive Council Resolution No. 11 of 2025, in effect since March 3, 2025, lets a Dubai free zone company operate on the mainland through a DET branch license or a temporary permit, without setting up an entirely separate entity.
Under the resolution, a branch license still runs at AED 10,000 a year, and a temporary permit costs AED 5,000 for up to six months — these figures remain current heading into 2027. The free zone company must keep separate financial records for its mainland activity under either option.
Expert Perspective
“Founders ask us which license is cheapest. The better question is where their customers are,” said Haseeb Hamdani, FCCA, UAE-CA, of Bestax Chartered Accountants, on mainland company formation in Dubai. “Once we know that, the structure, the tax position and the license usually pick themselves.”

Conclusion
The license is the easy part. The corporate tax registration deadline and the filing obligations that follow it are what actually determine whether a UAE company stays compliant — and with the 2025 penalty waiver now closed, getting registration right the first time matters more heading into 2027 than it did a year ago.
