Missed the 30 September Corporate Tax Deadline? What to Do Now

If your company runs a January to December financial year, your UAE Corporate Tax return and payment for FY2025 were due on 30 September 2026. If that date has passed without a filing, you are not alone, and the situation is very fixable. But the clock is already running, and what you do in the next few weeks decides whether this stays a small, fixed cost or turns into an expensive one.

This guide covers what has already been charged, what keeps growing, the misunderstanding that catches zero-tax businesses, and a practical plan for the next seven days.

What Has Already Happened

The Federal Tax Authority does not send a reminder or grant an informal grace period. Penalties apply automatically from the day after the deadline.

If you have not filed yet, you have already incurred the first AED 500. Because part of a month counts as a full month, filing on 2 October and filing on 29 October cost the same. The second AED 500 is what you can still avoid.

Filing and Paying Are Two Separate Clocks

This is the detail most people miss. The late filing penalty stops the moment the return is submitted. The late payment charge only stops when the tax is actually paid.

So if cash is tight, file anyway. Submitting the return caps the filing penalty, even if the payment follows a few weeks later. Waiting to file until you can also pay means both penalties keep running.

On the payment side, 14% per annum works out to roughly 1.17% a month. On a tax bill of AED 90,000, that is a little over AED 1,000 added every month the balance stays unpaid. Our penalty calculator will total this up for your own figures and dates.

"But We Don't Owe Any Tax"

This is the most expensive misunderstanding in UAE tax right now, and it is the reason many small businesses are late without realising it.

If your profit was under AED 375,000, if you qualify for Small Business Relief, or if you are a free zone company paying 0%, you still had to file a return by 30 September. These are reliefs you claim inside the return, not exemptions from filing it. The late filing penalty is charged on the missing return, not on the tax owed, so a business with zero liability pays exactly the same AED 500 a month as one owing six figures.

There is a second reason to file quickly if you rely on Small Business Relief: it has to be elected in the return itself. Until the return is in, you have not claimed it.

Can the AED 10,000 Registration Penalty Still Be Waived?

Only relevant if you also registered late. Under the FTA's penalty waiver initiative, introduced by Cabinet Decision in 2025, the late registration penalty is waived if you file your first corporate tax return within seven months of your first tax period ending. It applies to the first tax period only.

If your first tax period ended on 31 December 2025, that window closed on 31 July 2026, and the waiver is no longer available. If your first period ended on a different date, or this is not your first return, check your own dates before assuming the penalty stands either way. Our late corporate tax filing page walks through how the dates work.

If you have not registered at all, that is now the first job, because a return cannot be filed without a Tax Registration Number. Our guide to corporate tax registration deadlines explains how the timing works.

Your 7-Day Plan

Days 1 to 2: Establish where you stand

• Log in to EmaraTax and confirm you are registered and what tax period is showing as overdue

• Confirm whether you are filing as a mainland company, a free zone company, or a Qualifying Free Zone Person

• Check whether your revenue was AED 3 million or below, so you know whether Small Business Relief is available

Days 3 to 5: Get the numbers ready

• Close the FY2025 books and reconcile every bank account to its 31 December balance

• Produce your financial statements, audited if your free zone or QFZP status requires it

• Adjust accounting profit to taxable income: add back fines and penalties, add back half of entertainment costs, remove personal spending. Our corporate tax calculator gives a quick estimate of the result

Days 6 to 7: File, then pay

• Submit the return through EmaraTax, electing any relief you qualify for

• Pay any tax due as soon as you can, since interest runs separately

• Save the submission acknowledgement and payment confirmation with your records

If your bookkeeping is up to date, this really can be done in a week. If it is not, be honest about that now. Rushing out a return you know is wrong only swaps a late filing penalty for a correction later.

If You Have to Fix the Numbers Later

If you file quickly on your best available figures and then find an error, you can correct it through a voluntary disclosure. The penalty is 1% of the tax difference for each month since the original deadline, which is far lower than the 15% charge plus monthly interest that applies if the FTA finds the error in an audit. Correcting it yourself is always the cheaper route, and our piece on what triggers an FTA audit covers the mismatches to check first.

If you believe a penalty was applied unfairly, you can request a reconsideration from the FTA within 40 business days of being notified of it. That works best with a genuine, documented reason, not simply a missed date.

Why This Happened, and How to Stop It Happening Again

Almost every late return we see has the same cause: the books were not ready when the deadline arrived. The return itself takes hours. A year of unreconciled transactions takes weeks.

The fix is not a reminder in your calendar. It is monthly bookkeeping habits that keep your numbers current, so filing becomes a formality. Your FY2026 return is due on 30 September 2027, and the work for it is happening right now. If you are coming off Small Business Relief, plan for what changes once it ends.
