Corporate Tax has been live in the UAE long enough now that the basics should be settled. Yet every week we still talk to business owners who believe at least one of the following: that small businesses don't need to register, that free zone companies are automatically exempt, or that a company with no sales has nothing to file.
All three are wrong, and each one carries a penalty attached. Let's go through what's actually true.
Who must register: almost certainly you
Every juridical person in the UAE — every LLC, FZE, FZC, and similar entity — must register for Corporate Tax with the FTA. Profitability is irrelevant. Size is irrelevant. A dormant company that hasn't invoiced a single customer still has to register.
Natural persons (sole proprietors, freelancers operating in their own name) get a threshold: registration is required only once business turnover exceeds AED 1 million in a calendar year. We've covered that rule in detail in our sole proprietorship guide.
Registration deadlines are tied to your trade licence issue month under the FTA's published timeline, and missing yours costs a fixed AED 10,000 — one of the most commonly issued penalties in the entire regime, precisely because so many owners assumed registration didn't apply to them.
The filing deadline: 9 months, counted from your year end
Your Corporate Tax return, and any payment due, must be submitted within nine months of the end of your tax period. For a company with a December year end, that means 30 September of the following year. A March year end means end of December. The deadline is personal to your financial year — there is no single UAE-wide filing date, which is exactly why businesses miss it.
Late filing penalties accumulate monthly: AED 500 per month for the first twelve months, doubling to AED 1,000 per month from the thirteenth month onward. This isn't a one-off fine you pay and forget. It grows every month the return stays unfiled.
Small Business Relief: genuinely useful, frequently misunderstood
If your revenue is AED 3 million or less, you can elect Small Business Relief and be treated as having no taxable income for that period — effectively paying zero Corporate Tax. It applies to tax periods ending on or before 31 December 2026, which makes the current period the one to get right.
Two things people miss:
- It's an election, not automatic. You claim it in a filed tax return. No return, no relief — which means an unregistered or non-filing business can't benefit from it at all.
- Relief from tax is not relief from compliance. You still register, still file, still keep records for seven years.
The free zone 0%: real, but narrower than the marketing suggests
Qualifying Free Zone Person (QFZP) status allows 0% Corporate Tax — but only on qualifying income, and only if you meet all the conditions: adequate substance in the zone, audited financials, staying within de minimis limits on non-qualifying revenue, and activities that fall within the qualifying list.
The version many free zone companies believe — "we're in a free zone, so we pay no tax" — is not the rule. Trade with the UAE mainland, for instance, is generally not qualifying income. Getting QFZP status wrong doesn't just cost you the 0% rate; it can disqualify you from it for years. If your free zone company's position isn't crystal clear, it's worth an hour of proper assessment before your first return locks anything in.
Zero sales? You still file.
This is the one that catches dormant companies: a registered business must file a Corporate Tax return for every tax period, even with zero revenue and zero activity. A nil return is still a return. Skipping it because "there was nothing to report" triggers the same monthly late-filing penalties as any other missed return.
The same logic applies on the VAT side for registered businesses — we've written up the VAT deadlines and nil-return rules separately here.
What this costs to get right, versus getting it wrong
Here's the comparison that matters. Professional Corporate Tax registration done affordably costs a few hundred dirhams — our Corporate Tax registration service is currently AED 199 as a limited period offer, and annual return filing starts from AED 599. The penalty for late registration alone is AED 10,000, and late filing adds AED 500 every month. The maths isn't subtle.
For businesses that want the whole thing handled — registration, filing, bookkeeping, and the record-keeping that supports it — our monthly packages start at AED 299 with Corporate Tax registration and filing included.
