Two café owners are arguing on WhatsApp. (This is a composite, but you know both of these people.)
Owner A: "Bro, stay under 375. The moment you cross it, they take 9% of everything."
Owner B: "That's not how it works. It's 9% of the extra only."
Owner A: "My cousin's accountant said..."
Owner B: "Your cousin's accountant is why your cousin got fined."
Owner B is right, and the difference is worth real money. Let's settle the whole thing with actual numbers.
First: it's a slab, not a cliff
UAE Corporate Tax is 0% on taxable income up to AED 375,000 and 9% only on the portion above it. Crossing the line does not re-tax the first 375,000.
| Taxable income | Tax due | How |
|---|---|---|
| AED 300,000 | AED 0 | Under the threshold |
| AED 375,000 | AED 0 | Exactly at it |
| AED 400,000 | AED 2,250 | 9% × 25,000 |
| AED 500,000 | AED 11,250 | 9% × 125,000 |
| AED 1,000,000 | AED 56,250 | 9% × 625,000 |
The fear version, "cross 375 and pay 9% of everything", would make the tax on AED 500,000 equal to AED 45,000. The real number is AED 11,250. That's the size of the misunderstanding: a factor of four.
So no, there is no reason to sandbag your December sales to "stay under." Growing past the threshold always leaves you with more money, not less.
Second: 375,000 of what, exactly
Here's the mistake hiding underneath the first one: the threshold applies to taxable income, roughly your accounting profit with some adjustments, not your revenue.
A trading company can turn over AED 4 million and, after cost of goods, rent, salaries and everything else, end the year with AED 320,000 of profit. Tax due: zero. Meanwhile a lean consultancy billing AED 600,000 with almost no costs might clear AED 450,000 of profit and owe 9% on the 75,000 above the line: AED 6,750.
Revenue tells you how busy you are. Profit tells you what you owe. Conflating them is how people terrify themselves in both directions.
Third: the other 3-million number
There's a second threshold that gets tangled up with the first: Small Business Relief. If your revenue (this one is revenue) is AED 3 million or less, you can elect to be treated as having no taxable income for that period, effectively pressing pause on Corporate Tax while you're small. It's elective, it applies to tax periods within the relief window, and it has conditions.
Three things people miss about it:
- It doesn't exempt you from registering. Everyone in scope registers, relief or not.
- It doesn't exempt you from filing. You still file a return; the relief is claimed in it.
- It's a choice with trade-offs, for instance around carrying losses, so "obviously take it" isn't always obvious. This one's genuinely worth ten minutes with a professional.
Fourth: the calendar that actually matters
Corporate Tax runs on your financial year, and the return is due within nine months of your year-end. December year-end → file by 30 September. March year-end → file by 31 December. Registration, meanwhile, applies to essentially everyone doing business, including free zone companies (who have their own regime and conditions, a topic for its own article) and including businesses that will owe zero.
The pattern in every UAE tax rollout so far: the penalties that actually hit people early are rarely about the tax. They're about the admin: late registration, late filing, sloppy records. The boring stuff.
What this means for your books
Every question in this article is answered by one thing: a ledger that's actually current.
"Am I near the threshold?" is a profit question. You can only see it if income and expenses are booked as they happen, not reconstructed in a heroic January weekend. "Do I qualify for relief?" is a revenue question. Same requirement. "Can I defend the numbers?" is a records question. The FTA's nine-month deadline is generous precisely because they expect the file behind the return to be complete.
This is exactly why Saabi keeps a Corporate Tax card live on your dashboard: it projects your year's taxable profit against the AED 375,000 threshold continuously, from the ledger, all year. Not because the math is hard (you've just seen all of it) but because the answer should never be a surprise you meet in month nine.
Owner B, if you're reading: forward this to Owner A. And to the cousin.
