Once your corporate tax registration in UAE is approved, the Federal Tax Authority (FTA) gives you a Corporate Tax Registration Number (TRN) and a registration certificate. From then on, you have three ongoing jobs: keep proper books, file one corporate tax return a year within nine months of your financial year-end, and pay any tax due by that same date.
That return is required even if your company owes nothing. Below is what each step looks like in practice, with the dates, thresholds, and penalties that apply in 2026.
What do you get once your registration is approved?
You get your TRN and a Corporate Tax Registration Certificate, both issued through EmaraTax, the FTA’s online tax portal. When you submit your application, the system gives you a reference number so you can track it. Approval usually comes within about 20 business days if your documents are complete.

If the FTA needs more details, you’ll get an email and a notice on your EmaraTax dashboard. Reply fast. An unanswered request can hold up your TRN or lead to a rejection.
Your TRN goes on every return, payment, and letter you exchange with the FTA. Registration itself doesn’t mean you owe tax. It simply puts you on the FTA’s books, whether you end up paying 0% or 9%. The FTA’s own corporate tax registration page sets out who must register and how.
Quick tip: The day your certificate arrives, write down your financial year-end and set a reminder for six months after it. That gives you three clear months to prepare your return before the deadline.
When is your first corporate tax return due?
Your first return is due nine months after the end of your first tax period. For most businesses, the tax period is simply the financial year you prepare accounts for. Any tax you owe must be paid by the same date.
You don’t have to file and pay on the same day. You can submit the return first and pay later, as long as both happen before the deadline. Here’s how the dates work for common year-ends:
| Financial year ends | Return and payment due |
| 31 December 2025 | 30 September 2026 |
| 31 March 2026 | 31 December 2026 |
| 30 June 2026 | 31 March 2027 |
| 31 December 2026 | 30 September 2027 |
Registered late? The AED 10,000 late registration penalty can be waived if you file your first return (or annual declaration, for an exempt business) within seven months of the end of your first tax period, instead of the usual nine. The waiver is applied automatically in EmaraTax when you qualify, so there’s no separate form to fill in.
What records do you need to keep from day one?
You need complete accounting records for every transaction, and you must keep them for at least seven years after the end of each tax period. Your tax return is built from your financial statements, so solid Accounting & Bookkeeping is the real foundation of corporate tax compliance. If the books are wrong, the return will be too.
Keep these on file:
- Sales and purchase invoices, receipts, and credit notes.
- Bank statements for every business account, reconciled each month.
- Contracts, lease agreements, and loan documents.
- Your general ledger, trial balance, and payroll records.
- A fixed asset register showing what you own and how it’s depreciated.
The accounting method you can use depends on your revenue:
| Revenue in the tax period | Accounting basis you can use |
| AED 3 million or less | Cash basis allowed (or accrual) |
| AED 50 million or less | IFRS for SMEs (a simpler version of IFRS) |
| Above AED 50 million | Full IFRS |
Cash basis means you record income when money actually lands in your account. Accrual means you record it when you earn it, even if the client pays later. Once you cross AED 3 million, you must switch to accrual.
A simple monthly routine prevents most year-end headaches. Reconcile your bank accounts, keep personal and business spending apart, store receipts digitally, and flag any deals with owners or related companies as they happen. Failing to keep proper records carries a penalty of AED 10,000, rising to AED 20,000 for a repeat offence.
Do you need audited financial statements?
For corporate tax purposes, most small and mid-sized companies don’t. For tax periods starting on or after 1 January 2025, Ministerial Decision No. 84 of 2025 requires audited financial statements only from:
- Standalone businesses with revenue above AED 50 million in the tax period.
- Qualifying Free Zone Persons, whatever their revenue. The audit is one of the conditions for keeping the 0% rate.
- Every tax group, which must prepare audited aggregated financial statements.
Tax is not the only rule that can require an audit. Your free zone licence terms, the Commercial Companies Law, or a bank loan agreement may ask for one too. If you need an audit, book your auditor early. Auditors get busy in the months before the September filing rush.
How much corporate tax will you actually pay?
The first AED 375,000 of taxable income is taxed at 0%, and everything above that is taxed at 9%. Taxable income is not the same as the profit on your bank statement. It starts with your accounting profit, then gets adjusted for items the law treats differently.

For example, entertainment for clients and suppliers is only 50% deductible, while staff entertainment is fully deductible. So if your adjusted taxable income comes to AED 500,000, you pay 9% on the AED 125,000 above the threshold, which is AED 11,250.
Free zone companies that meet the Qualifying Free Zone Person conditions pay 0% on qualifying income and 9% on the rest. Keeping those two types of income clearly separated in your books is what protects that 0% rate.
Should you claim Small Business Relief?
If your revenue is AED 3 million or less, you can usually elect Small Business Relief and be treated as having no taxable income for that period. You make the election inside your tax return, and you have to make it again every year. The FTA explains the full rules on its Small Business Relief page.
A few conditions and trade-offs matter here:
- Revenue must be AED 3 million or less in the current period and in every previous tax period. Cross the line once and you lose the relief for good.
- It only covers tax periods that end on or before 31 December 2026. After that, the normal 0% and 9% rates apply.
- Qualifying Free Zone Persons and members of large multinational groups (consolidated revenue above AED 3.15 billion) can’t use it.
- Losses from relief years can’t be carried forward to reduce tax in later years.
That last point is worth thinking about. If you expect a loss this year and profits later, it can make sense not to elect the relief, so the loss can be used against future profits. Either way, you still register, file a return, and keep seven years of records.
Do deals with related parties change anything?
Yes. If you buy from, sell to, or lend money to owners, family businesses, or group companies, the price must be at arm’s length. That means the same price two unrelated businesses would agree on.
Businesses with related-party dealings may also need to file a transfer pricing disclosure form with their return. Companies using Small Business Relief don’t need transfer pricing paperwork, but their prices must still be fair. Tag these transactions in your books as they happen, not at year-end.
How do you file and pay your return on EmaraTax?
Filing happens entirely online. Here’s the order most businesses follow:
- Close your books for the year and prepare your financial statements under the right standard.
- Work out taxable income: start from accounting profit, then add back non-deductible costs and remove exempt income.
- Log in to EmaraTax and open the Corporate Tax return for the correct tax period.
- Enter your figures, upload financial statements where required, and select any reliefs you’re claiming, such as Small Business Relief.
- Review everything, submit, and save the acknowledgement.
- Pay any tax due from your EmaraTax account before the deadline. Pay a few days early so the money clears in time.
Found a mistake after filing? Correct it yourself through a voluntary disclosure on EmaraTax. It costs far less than waiting for the FTA to spot the error in a review.
What happens if you miss a deadline?
Penalties apply automatically once a deadline passes. No audit or warning letter is needed first. These are the main ones:
| Missed obligation | Penalty |
| Registering late | AED 10,000 (can be waived, see above) |
| Filing the return late | AED 500 a month for the first 12 months, then AED 1,000 a month |
| Paying tax late | 14% a year on the unpaid tax, charged monthly (since 14 April 2026) |
| Not keeping proper records | AED 10,000, or AED 20,000 for a repeat |
| Deregistering late | AED 1,000 a month, up to AED 10,000 |
Late filing and late payment are separate charges, so both can hit the same return. Say you owe AED 27,000 and file and pay six months late. The filing penalty is AED 3,000, and the payment penalty adds about AED 1,890, before the tax itself.
What changes do you need to tell the FTA about?
You must update your tax record within 20 business days of any change. That includes your company name, address, email, licence activities, legal form, or articles of association. You do this through an amendment request in EmaraTax, with the new documents attached.

If you close, sell, or merge the business, apply to deregister within three months of that date. Cancelling your trade licence doesn’t cancel your tax registration. The FTA only deregisters you once all returns are filed and all tax and penalties are paid.
Your first-year checklist
Pin this list somewhere you’ll see it:
- Save your TRN and certificate, and note your financial year-end.
- Pick the right accounting basis and keep books up to date every month.
- Check whether you need an audit, and book your auditor early if you do.
- Decide on Small Business Relief before you file, not while you file.
- File and pay within nine months of your year-end.
- Report any business changes to the FTA within 20 business days.

Frequently asked questions
How long does it take to get a TRN after corporate tax registration in UAE?
Usually up to about 20 business days, as long as your application and documents are complete. If the FTA asks for more information, the clock effectively pauses until you reply, so answer any request on EmaraTax quickly.
Do I need to file a corporate tax return if my company made no profit?
Yes. Every registered business must file a return within nine months of its year-end, even with zero profit or a loss. Skipping it triggers late filing penalties of AED 500 a month for the first year.
Is UAE corporate tax paid monthly or once a year?
Once a year. You pay any tax due by the same deadline as your return, nine months after your financial year ends. There are no monthly or quarterly corporate tax instalments.
Can I file my corporate tax return myself?
Yes. You can file directly on EmaraTax with your own login. Many owners still use an accountant or tax agent, because the return depends on accurate financial statements and correct tax adjustments.
What happens to Small Business Relief after 2026?
It only covers tax periods ending on or before 31 December 2026. After that, small businesses follow the normal rates: 0% on the first AED 375,000 of taxable income and 9% on the rest.
Conclusion
After corporate tax registration in UAE, your TRN marks the start of a yearly cycle, not the end of the job. Keep clean books under the right standard, hold records for seven years, and file your return and pay any tax within nine months of your year-end, even when you owe nothing. Decide on Small Business Relief and audit needs early. A good result is simple: no penalties, no surprises, and a return that matches your books.
