If your company’s financial year ended on 31 December 2025, one date now matters more than any other on your compliance calendar: 30 September 2026<\/strong>. That’s the day your first corporate tax return \u2014 and any tax you owe \u2014 falls due with the Federal Tax Authority (FTA).<\/p>

It sounds like plenty of time. It isn’t, for two reasons. First, this is a genuinely new filing obligation for most Dubai businesses, so there’s no “last year’s process” to simply repeat. Second, the FTA has just overhauled how it penalizes lateness, and the new rules are stricter in some ways and more forgiving in others \u2014 which means a lot of the advice still circulating online is already out of date. Here’s what’s actually true right now, and exactly what it costs if the deadline passes you by.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

The rule itself is simple: every taxable person must file their corporate tax return<\/a>, and pay any tax owed, within nine months of the end of their financial year.<\/strong> This nine-month window comes from Federal Decree-Law No. 47 of 2022, the founding legislation for UAE corporate tax.<\/p>

For the most common case \u2014 a business running a standard calendar-year (1 January to 31 December), the numbers land like this:<\/p>

Financial year end<\/th>Filing & payment deadline<\/th><\/tr><\/thead>
31 December 2025<\/td>30 September 2026<\/td><\/tr>
31 January 2026<\/td>31 October 2026<\/td><\/tr>
31 March 2026<\/td>31 December 2026<\/td><\/tr><\/tbody><\/table><\/div>

Filing and payment are treated as one single obligation, not two. You can’t submit the return on time and settle the tax bill later \u2014 both need to be done by the same date, and there is currently no general extension mechanism. The FTA does not accept “our auditor was busy” or “we needed more time to reconcile the books” as grounds to push the date back.<\/p>

This also applies whether or not you actually owe anything. A company sitting entirely inside the 0% band (taxable income under AED 375,000), a business relying on Small Business Relief, or a Qualifying Free Zone Person reporting 0% on its qualifying income \u2014 all of them still have to file a return. Zero tax due does not mean zero filing obligation.<\/p>

Missing the deadline doesn’t trigger one penalty \u2014 it can trigger three separate ones, and they stack.<\/p>

1. Late filing penalty<\/strong> Set under Cabinet Decision No. 75 of 2023, this is a flat AED 500 for every month (or part of a month)<\/strong> the return remains unfiled, for the first 12 months. From month 13 onward, it rises to AED 1,000 per month<\/strong>, and it keeps accruing until the return is actually submitted.<\/p>

2. Late payment penalty \u2014 this one changed recently<\/strong> If you owe tax and don’t pay it by the deadline, a separate penalty applies to the unpaid amount. Until recently this was a front-loaded structure (an immediate percentage plus a monthly add-on). That changed under Cabinet Decision No. 129 of 2025<\/strong>, which took effect on 14 April 2026<\/strong> and unified the penalty framework across Corporate Tax, VAT, and Excise Tax. Under the new rules, late payment now accrues at a flat 14% per annum<\/strong>, calculated monthly on the outstanding balance, with no cap. It’s a simpler formula, but the meter never stops running until the tax is paid in full.<\/p>

3. Late registration penalty<\/strong> A flat AED 10,000<\/strong> applies if a business registers for corporate tax<\/a> <\/strong>after its deadline \u2014 and this one exists independently of whether you’ve filed a return or paid anything at all.<\/p>

What this looks like in real numbers<\/h4>

Take a business with AED 500,000 in taxable income. Its tax liability at 9% on the amount above the AED 375,000 threshold works out to AED 11,250. If it misses the 30 September 2026 deadline by six months, the cost stacks up roughly like this:<\/p>
