VAT and Corporate Tax compliance mistakes usually aren't about dishonesty — they're about genuinely misunderstanding how the rules apply. Here are the ones that come up most often.
The Mistakes
- Assuming registration is optional below a vaguely remembered threshold
VAT and Corporate Tax each have specific, currently published thresholds — check the exact figure that applies to your business rather than relying on a number you half-remember. Check it with the Tax Assistant. - Applying the 9% Corporate Tax rate to total profit instead of the taxable portion
Corporate Tax only applies to profit above the AED 375,000 tax-free threshold — applying 9% to your entire profit overstates your own tax bill. Check it with the UAE Corporate Tax Calculator. - Misclassifying VAT-deductible costs
Not every business expense qualifies for VAT reclaim — misclassifying costs can lead to either underclaiming (leaving money on the table) or overclaiming (an FTA compliance risk). Check it with the UAE VAT Calculator. - Issuing invoices missing mandatory VAT fields
A compliant UAE tax invoice needs specific fields — TRN, VAT breakdown, sequential invoice number — that generic invoice templates often miss. Check it with the UAE Invoice Generator. - Assuming free zone status automatically means 0% Corporate Tax
Free zone companies must meet specific qualifying income and de minimis conditions to maintain their 0% rate — it isn't automatic simply by being registered in a free zone. Check it with the Tax Assistant.
The Common Thread
Almost every mistake on this list comes down to the same root cause: relying on a rule of thumb, an outdated assumption, or someone else's number instead of checking your own specific figures. None of the tools linked above require a sign-up, and each takes under a minute — there's rarely a good reason to skip the check.
