VAT vs Corporate Tax in the UAE: What’s the Difference?

UAE businesses now navigate two separate federal taxes: Value Added Tax (VAT) at 5%, in place since 2018, and Corporate Tax at 9%, introduced for financial years starting on or after 1 June 2023. They are administered by the same authority (the FTA, through EmaraTax) but they are fundamentally different taxes — different base, different thresholds, different filing rhythms, and separate registrations. Confusing the two is a common source of costly “mismatch” flags in audits.

This guide lays out the difference clearly, including the one number that trips everyone up: AED 375,000, which means something entirely different for each tax.

The fundamental difference: what is being taxed

The single most important distinction is the tax base — what each tax is actually applied to:

• →VAT is an indirect, transaction-based consumption tax on the gross value of your supplies (revenue). You charge 5% on taxable sales, pay 5% on purchases, and remit the difference. Crucially, VAT is not your money — you collect it from the customer on behalf of the FTA. The end consumer bears it; for the business it is meant to be tax-neutral.
• →Corporate Tax is a direct tax on your net business profit — revenue minus allowable expenses. It is your own liability, paid out of your earnings. Where VAT flows through your accounts, Corporate Tax is a final assessment of what your business actually made.

The AED 375,000 trap: same number, opposite meaning

Both taxes feature AED 375,000, and this is where confusion costs people. The figure means completely different things:

• →For VAT, AED 375,000 is the mandatory registration threshold — based on revenue (taxable supplies and imports) over a rolling 12-month period. Cross it and you must register for VAT. There is also a voluntary registration threshold of AED 187,500.
• →For Corporate Tax, AED 375,000 is the 0% profit band — a small-business exemption built into the rate. You pay 0% on taxable income up to AED 375,000 and 9% only on profit above it. It has nothing to do with registration.

Worked example: a business paying both

Imagine a Dubai company selling a service for AED 1,000. On the VAT side, it charges the customer 5% (AED 50) on top, so the customer pays AED 1,050 — and that AED 50 is a liability the business remits to the FTA, not income. Multiply across all sales and purchases for the period, net it off, and that is the VAT return.

On the Corporate Tax side, at year end the business totals its revenue, subtracts allowable expenses to reach its profit, and applies the rate. If profit is AED 500,000, the first AED 375,000 is taxed at 0% and the remaining AED 125,000 at 9% — Corporate Tax of AED 11,250. The two taxes run independently but simultaneously: VAT managed monthly or quarterly as cash moves, Corporate Tax assessed once a year on the bottom line.

Registration and filing: separate in every way

These are entirely separate obligations, and a key asymmetry catches businesses out:

• →Corporate Tax registration is mandatory for all taxable persons — there is no minimum revenue or profit threshold. Even a business that will pay 0% must register.
• →VAT registration is threshold-based — mandatory only once taxable supplies exceed AED 375,000 in a 12-month period (or expected in the next 30 days).
• →Each tax has its own registration and its own TRN. They are not interchangeable.
• →Filing rhythms differ: VAT is filed quarterly (or monthly for large businesses), within 28 days of period end; Corporate Tax is filed once a year, within nine months of the tax-period end.

Why consistency between them matters

Because both taxes draw on the same underlying business activity, the FTA increasingly cross-checks them. A business filing active VAT returns but with no Corporate Tax registration creates a visible mismatch — a signal that invites scrutiny. In 2026, VAT and Corporate Tax data are assessed together, not in isolation, so keeping the two consistent is itself a compliance discipline.

Most UAE businesses over the VAT threshold deal with both taxes at once: VAT on every transaction, Corporate Tax on the annual result. The ones who stay clean are those whose books support both views — accurate VAT treatment on each invoice, and accurate profit calculation for the year.

The practical takeaway

VAT and Corporate Tax are two different taxes that happen to share an administrator and a famous number. VAT is 5% on supplies, collected for the FTA, filed quarterly. Corporate Tax is 9% on profit above AED 375,000, your own liability, filed annually. Register for each where required, keep their TRNs and filings separate, and keep the underlying books consistent so the two never contradict.

A single, accurate set of books is what makes dual compliance manageable. Deskloc Flow handles VAT treatment on every invoice and computes your Corporate Tax position from the same records — so both taxes draw on one clean source of truth, and the mismatches that trigger audits never arise.
