Your first UAE corporate tax return is due even if you owe zero

✓ Verified against FTA guidance & reviewed with an FTA-registered tax practitioner — 23 Jul 2026

Here is the sentence accountants hear from founders every single week: “We didn’t make any profit, so we don’t need to file.” It is wrong — and it is wrong in a way that costs AED 500 for every month, or part of a month, you are late, on a company that may have earned nothing at all.

This guide gives you the filing formula, the full deadline table for every tax period end, what actually goes inside a zero-sales return — because it is not zeros in every box — and three traps that catch zero-revenue companies specifically, including one that makes founders believe they filed when they didn’t.

Watch: zero revenue, and still a return to file

Registered means filing — even at zero

This is not an interpretation. In its official statement, the Federal Tax Authority says all Corporate Taxable Persons, regardless of the level of income, have a legal obligation to file their tax returns. In normal language: if your company is registered for corporate tax, it files — no matter what it earned. Zero revenue, zero profit, a loss, a dormant license kept for a visa, a 0% free zone rate, Small Business Relief: all of them file.

And don’t wait for a personal warning first. The FTA does publish reminders, but corporate tax runs on self-assessment — nobody calculates this for you and nobody chases you to do it. Knowing your tax period, preparing the return and filing on time stays with you, whether or not a reminder ever reaches your inbox.

Your filing deadline is a formula, not a date

Your corporate tax return — and any payment due — must be submitted within nine months from the end of your tax period. 30 September 2026 is only the answer for companies whose tax period ended 31 December 2025. Different period end, different deadline. And a brand-new company’s very first tax period can legally run anywhere from six to eighteen months, so it may not follow the calendar year at all.

Your deadline by tax period end date

Tax period ended	File & pay by	Late by 6 months costs
31 Dec 2025	30 Sep 2026 — most companies	AED 3,000
31 Jan 2026	31 Oct 2026	AED 3,000
28 Feb 2026	30 Nov 2026	AED 3,000
31 Mar 2026	31 Dec 2026	AED 3,000
30 Apr 2026	31 Jan 2027	AED 3,000
31 May 2026	28 Feb 2027	AED 3,000
30 Jun 2026	31 Mar 2027	AED 3,000
31 Jul 2026	30 Apr 2027	AED 3,000
31 Aug 2026	31 May 2027	AED 3,000
30 Sep 2026	30 Jun 2027	AED 3,000
31 Oct 2026	31 Jul 2027	AED 3,000
30 Nov 2026	31 Aug 2027	AED 3,000

Dates follow the FTA’s month-end convention shown in its official examples. The penalty column shows late-filing penalties only — any unpaid tax carries its own separate charge. Always confirm your exact tax period and due date in your EmaraTax account.

What being late actually costs

The penalty meter is set by Cabinet Decision No. 75 of 2023, and the math is simple: AED 500 for every month — or part of a month — you are late for the first twelve months, rising to AED 1,000 per month from month thirteen. One day into a new month counts as a full month.

What a zero-sales return actually contains

Most founders assume that filing with no sales means opening EmaraTax and typing zero into every box. That can be an incorrect return. There are two paths, and which one you’re on changes everything.

Path 1 — Small Business Relief: the FTA’s “easy mode”

If your company’s revenue has never exceeded AED 3,000,000 — not this tax period, not any previous one — you can tick the Small Business Relief election inside the return, and the filing becomes much simpler: fewer questions, no financial statements to attach. Three things to know:

1. The box doesn’t tick itself. Nobody applies this for you. The election appears in the return based on how you answer the opening questionnaire — and practitioners report most mistakes happen in those opening questions, before people ever reach the election screen.
2. Easy mode is not no mode. You still submit the return, and you still keep the records proving your revenue and eligibility. It is a simplified return, not an exemption from filing or from recordkeeping.
3. It’s temporary. Under the current rules the relief only covers tax periods ending on or before 31 December 2026 — for most companies, this is the last year it is available.

And one caution for loss-making companies: electing the relief means giving up the tax loss you could otherwise carry forward against future profits. A company with AED 2,500,000 of revenue and AED 2,700,000 of costs has a 200,000-dirham loss that may be worth more carried forward than the relief is worth today. That is a decision to make deliberately, not a box to tick by reflex.

Path 2 — no relief: the return reflects what actually happened

If you don’t tick that box — or can’t — then even with zero sales, your accounts and return must reflect the real picture. Think about it: your company paid for its license. It paid bank charges. Perhaps salaries, including anything the company paid you. Equipment losing value year by year — accountants call that depreciation. And the money you put in from your own pocket to keep the company alive is a transaction too: it sits in the books as shareholder funding or a loan, alongside what was in the accounts on the first day of the period and the last. Zero sales does not mean zero activity — and the numbers have to show it.

Three traps that catch zero-revenue companies

1. Dormant does not mean deregistered

A dormant company is one that exists on paper but isn’t really doing anything — the license is there, maybe renewed every year, but no clients, no sales, no activity. Maybe you started it for a project that never took off. Not trading does not automatically end its corporate tax obligations: an unused company keeps filing for as long as it stays registered.

If the business genuinely ends — you formally close it, sell it, or merge it — there is an official exit step: corporate tax deregistration, which you generally need to apply for within three months of that event. The FTA will not complete it until every outstanding return is filed and any tax or penalties are settled. Leaving the license unused in a drawer is not deregistration, and applying late carries its own penalty.

2. Draft does not mean filed

EmaraTax has a draft stage and a validation stage, and taxpayers genuinely believe that saving a draft — or passing validation — means the return is in. It isn’t. After a successful submission, EmaraTax gives you a downloadable submission acknowledgment (think of it as your official receipt) and the FTA sends an acknowledgment email. Save both; that is your proof. Practitioners report clients also typically receive an SMS and can download a return summary showing the submitted figures — useful extra confirmation, but the acknowledgment and the email are the ones to keep. Completed is not filed. Validated is not filed. Acknowledged is filed.

3. Your deadline is not everyone’s deadline

30 September 2026 is all over LinkedIn, and for tax periods that ended 31 December 2025 it is correct. But a March year-end, a June year-end, or a brand-new company whose first tax period runs six to eighteen months all produce different dates entirely — and some founders are relaxing with a deadline that has already passed. Check your exact tax period inside your EmaraTax account, not in a LinkedIn post.

The FTA cross-checks your VAT returns — a real case

One warning from live casework. A company filed its VAT returns correctly, showing revenue above AED 4,000,000 across the period — then declared under AED 3,000,000 on its corporate tax return in order to claim Small Business Relief. The FTA compared the two filings and flagged the mismatch.

File it in three steps

1. Confirm your tax period end date. It’s shown in your EmaraTax account — check it there rather than assuming December. Add nine months: that’s your filing and payment deadline.
2. Close the books and make the relief decision. Even at zero sales, gather the license costs, bank charges, any salaries, asset and funding records. If revenue has always been under AED 3,000,000, decide deliberately whether Small Business Relief beats carrying a loss forward.
3. File early, then watch the registered email. Two to three weeks of buffer costs nothing; the EmaraTax queue in the final week is exactly what you imagine. After filing, keep an eye on the company’s registered email — FTA clarification requests arrive there, typically with 5 to 20 business days to respond.

Frequently asked questions

My company had no revenue at all. Do I still have to file a corporate tax return?

Yes. The FTA states that all Corporate Taxable Persons must file regardless of the level of income. If the company is registered for corporate tax, the return is due within nine months of the end of its tax period — zero revenue, zero profit and nil tax due make no difference to the obligation.

What is the penalty for filing a corporate tax return late in the UAE?

AED 500 for each month, or part of a month, for the first twelve months, rising to AED 1,000 per month from the thirteenth month onwards. Part-months count as full months, and the penalty applies even when no tax is owed.

Can I just enter zero in every box of the return?

Not necessarily. If you elect Small Business Relief, the return is simplified and financial statements aren’t attached. If you don’t elect it, the return and supporting accounts must reflect what actually happened — license and operating costs, bank charges, salaries, depreciation, shareholder funding, and opening and closing balances. Zero sales does not mean zero activity.

Is my dormant company exempt from corporate tax filing?

No. An inactive company with a live license still files while it remains registered. Ending the obligation requires a formal cessation event, a corporate tax deregistration application — generally within three months of that event — and settlement of all outstanding returns and liabilities.

How do I know my return was actually submitted?

A saved draft or a passed validation is not a filed return. After a successful submission you can download a submission acknowledgment from EmaraTax and the FTA sends an acknowledgment email. Keep both as proof of filing.

Is Small Business Relief automatic if my revenue is under AED 3 million?

No. It must be elected inside the return, and eligibility depends on revenue staying under AED 3,000,000 in the current and all previous relevant tax periods. Under the current rules it applies only to tax periods ending on or before 31 December 2026, and a Qualifying Free Zone Person cannot elect it.
