VAT vs Corporate Tax in the UAE: Key Differences Every Owner Should Know

VAT and Corporate Tax are two different UAE taxes that owners often confuse. Compare what each taxes, the rates, thresholds, deadlines and registration — and whether you owe both.

A lot of UAE business owners use “tax” as a single word, but the country actually runs two separate business taxes that work in completely different ways: value added tax and Corporate Tax. They are administered by the same authority through the same portal, which adds to the confusion, yet they tax different things, have different thresholds, and run on different deadlines. Many businesses are liable for both at once.

Getting clear on the difference helps you register for the right things, file on the right schedule, and avoid penalties on either front.

VAT in one paragraph

VAT is a transaction tax. You add 5% to most of what you sell, you pay 5% on most of what you buy, and each period you hand the FTA the difference. The business is really a collection agent — the cost falls on the final consumer. What matters for VAT is your turnover of taxable supplies, which is why the threshold is set on supplies rather than profit. If you are new to it, our VAT registration guide and VAT filing walkthrough cover the essentials.

Corporate Tax in one paragraph

Corporate Tax is a profit tax. It is charged on the net profit your business actually earns, after expenses and the adjustments the law requires. The business bears the cost itself; there is no customer to pass it to. The first AED 375,000 of taxable income is taxed at 0% and the rest at 9%, and many small businesses pay nothing thanks to that threshold or Small Business Relief. Our Corporate Tax overview explains the mechanics.

Can you owe both?

Yes — and plenty of businesses do. They are independent of each other. A trading company over the VAT threshold will charge and file VAT every quarter, and if it makes a profit above AED 375,000 it will also pay Corporate Tax annually. One does not replace or reduce the other in any direct way.

It is equally possible to owe one and not the other. A business under the VAT threshold but carrying on commercial activity still needs to register for Corporate Tax. A business making losses might pay no Corporate Tax while still charging and filing VAT every period because its turnover is high.

The two registrations are separate. Your VAT TRN and your Corporate Tax registration number are different identifiers obtained through different applications. Holding one does not give you the other.

How the two taxes interact

A few practical points where VAT and Corporate Tax meet:

• VAT you collect is not your income. The 5% you charge customers belongs to the FTA; it should never be treated as revenue when working out Corporate Tax profit.
• VAT you cannot recover can be a cost. Where input VAT is genuinely irrecoverable, it usually forms part of the expense it relates to, which feeds into your accounts and therefore your Corporate Tax position.
• Good records serve both. The same bookkeeping that produces accurate VAT returns also produces the financial statements behind your Corporate Tax return, which is why solid record-keeping pays off twice.

A simple checklist for owners

To stay on top of both taxes:

1. Check your VAT position. Over AED 375,000 in taxable supplies? Register and file quarterly. Between AED 187,500 and AED 375,000? Voluntary registration is an option.
2. Register for Corporate Tax regardless. Almost every business must, even at 0%.
3. Track two sets of deadlines. VAT every period (28-day rule); Corporate Tax once a year (nine-month rule).
4. Keep one clean set of books that supports both returns.
5. Apply the reliefs you are entitled to on the Corporate Tax side.
