UAE Tax Rules 2026: The Complete Guide for Businesses and Online Sellers

Every month someone in Dubai asks me some version of the same question: “Is the UAE still tax-free?” The honest answer in 2026 is: there’s still no personal income tax, but businesses now live with VAT, corporate tax, excise tax and, very soon, mandatory e-invoicing. None of it is scary if you know the rules. Missing a registration or a deadline is what gets expensive.

This guide brings all the UAE tax rules for 2026 into one place, with links to my deeper guides on each topic.

This is general information, not tax advice. Rules change, so confirm with the Federal Tax Authority (FTA) or a registered tax agent before you act.

1. Corporate tax in 2026

The rates haven’t changed: 0% on the first AED 375,000 of taxable profit and 9% on anything above. Tax is charged on profit, not revenue, so good bookkeeping directly lowers your bill.

• Who registers: every UAE company (mainland and free zone), even if it expects to pay zero. Individuals running a business register once their business turnover passes AED 1 million in a calendar year.
• Return and payment: due within 9 months of the end of your financial year. For a 31 December 2025 year-end, that’s 30 September 2026.
• Small Business Relief: if your revenue is AED 3 million or less, you can elect to be treated as having no taxable income. The Ministry of Finance extended this relief to tax periods ending on or before 31 December 2029. You still have to register and file, and you can’t carry losses forward while you use it.

Full details, examples and the registration steps are in my UAE corporate tax guide for small businesses.

2. Free zone companies: 0% isn’t automatic

A free zone company can pay 0% only if it is a Qualifying Free Zone Person (QFZP). That means real substance in the UAE, audited accounts, arm’s-length pricing with related parties, and income that counts as “qualifying”.

The trap for online sellers: income from most sales to mainland customers and businesses is non-qualifying. If non-qualifying income goes above the de minimis limit (the lower of 5% of revenue or AED 5 million), you lose QFZP status for that year and the next four, and everything is taxed at 9%. I explain this in detail in my free zone 0% tax guide for e-commerce.

3. VAT: what changed on 1 January 2026

The basics stay the same: 5% VAT, mandatory registration once taxable supplies exceed AED 375,000 in 12 months, and optional registration from AED 187,500. Federal Decree-Law No. 16 of 2025 brought these changes from 1 January 2026:

• No more self-invoicing for reverse charge. When you account for VAT under the reverse charge (for example, on imported services), you no longer need to issue yourself a tax invoice. Keep the supplier’s invoice and supporting documents instead.
• A five-year limit on excess input VAT. Excess recoverable VAT must be claimed within five years from the end of the tax period it arose in. Older credits can expire, so check your balance. A transition window in 2026 lets businesses claim credits that are expiring.
• Input VAT can be denied where a purchase was linked to tax evasion and you knew, or should have known.

For registration, thresholds and how marketplace sales are treated, read my UAE VAT guide for online sellers.

4. Tax procedures: the new five-year window

Under Federal Decree-Law No. 17 of 2025 (also in force from 1 January 2026), you generally have five years from the end of a tax period to request a refund or use a credit, across corporate tax, VAT and excise tax. The FTA can also issue binding directions on how it applies the law. In practice, keep records for at least five years and don’t sit on refunds.

5. Excise tax on sweetened drinks

From 1 January 2026, the flat 50% excise tax on sweetened drinks was replaced by a sugar-based tier system (Cabinet Decision No. 197 of 2025): about AED 0 per litre for low sugar, AED 0.79 for moderate and AED 1.09 for high sugar. This matters if you import or sell beverages, including through an online store.

6. E-invoicing is coming

The UAE is moving to structured electronic invoices exchanged through Accredited Service Providers (ASPs). PDFs and scanned invoices will no longer count.

• Pilot and voluntary adoption from 1 July 2026
• Revenue of AED 50 million or more: appoint an ASP by 30 October 2026; mandatory from 1 January 2027
• Revenue below AED 50 million: appoint an ASP by 31 March 2027; mandatory from 1 July 2027

Penalties start at AED 5,000 per month for not being ready. My UAE e-invoicing guide explains what small businesses need to do now.

7. Penalties to avoid

Mistake	Penalty
Late corporate tax registration	AED 10,000 (waived if the first return is filed within 7 months of the end of the first tax period)
Late corporate tax return	AED 500 per month for the first 12 months, then AED 1,000 per month
Late payment	Interest at 14% per year on the unpaid amount
Errors found in an FTA audit	15% of the underpaid tax plus interest (voluntary disclosure is cheaper)
Not appointing an e-invoicing ASP on time	AED 5,000 per month

Your 2026 tax checklist

1. Confirm your company is registered for corporate tax, even if you expect to pay 0%.
2. Track your revenue monthly against the AED 375,000 VAT threshold.
3. Decide whether to elect Small Business Relief (revenue up to AED 3 million).
4. If you’re in a free zone, check what share of your income comes from mainland customers.
5. Review old VAT credits before the five-year limit removes them.
6. Start talking to accounting software providers about e-invoicing.
7. Diary the deadlines: corporate tax returns 9 months after year-end, VAT returns 28 days after each period.

Frequently asked questions

Is there income tax in the UAE in 2026?

No. There’s no personal income tax on salaries. Individuals only fall under corporate tax if they run a business with turnover above AED 1 million in a calendar year.

Do I pay corporate tax if my profit is under AED 375,000?

The rate is 0% on that portion, but you still need to register and file a return.

Is Small Business Relief still available?

Yes. It now covers tax periods ending on or before 31 December 2029 for resident businesses with revenue up to AED 3 million, subject to conditions.

Do small businesses need e-invoicing?

If you’re VAT-registered and your revenue is below AED 50 million, the current timeline makes it mandatory from 1 July 2027, with an ASP appointed by 31 March 2027.
