Most FTA penalties don't come from deliberate evasion — they come from small, avoidable process errors. Here are the ones UAE businesses run into most often.
Registering late
Once your taxable supplies cross AED 375,000 (looking back 12 months or forward 30 days), registration is mandatory — not optional, and not something you can back-date informally. Missing the window carries an administrative penalty based on how late the registration is.
Issuing invoices without a valid TRN
Every tax invoice must display your Tax Registration Number once you're registered. Invoices missing a TRN, or showing an incorrect one, can invalidate the customer's ability to reclaim input VAT — a problem that tends to surface during their audit, not yours.
Reclaiming input VAT on non-recoverable expenses
Certain categories — including most entertainment expenses and non-business-use motor vehicles — are specifically excluded from input VAT recovery, even though 5% VAT was genuinely paid on them. Claiming these anyway is a common reason FTA audits result in reassessments.
Getting zero-rated and exempt supplies confused
Zero-rated supplies (like most exports and certain healthcare and education services) still let you recover related input VAT. Exempt supplies (like most bare land and local passenger transport) do not. Treating an exempt supply as zero-rated overstates your input VAT recovery.
Missing the VAT return filing deadline
Returns are generally due 28 days after the end of each tax period (monthly or quarterly, depending on your assigned filing frequency). Late filing and late payment each carry separate penalties — filing on time but paying late doesn't avoid the payment penalty.
Not keeping records for the full retention period
Businesses must retain VAT-related records — invoices, credit notes, import/export documentation — for at least 5 years (longer for real estate-related records). Insufficient documentation during an FTA audit shifts the burden of proof onto the business.
Check your VAT calculation before you file.

A voluntary disclosure filed proactively with the FTA — before they catch the error themselves — generally results in a significantly lower penalty than the same mistake found during an audit. If you spot an error in a filed return, addressing it sooner rather than later is almost always the cheaper path.
