UAE VAT & Corporate Tax: the 2026 compliance calendar.

The UAE VAT and Corporate Tax compliance calendar runs on two separate cycles. VAT returns are filed through EmaraTax by the 28th day after each tax period, usually quarterly at a 5 per cent rate. Corporate Tax is filed once a year, within nine months of the financial year end, at 9 per cent above AED 375,000.

What does the UAE VAT and Corporate Tax compliance calendar cover?

UAE businesses now navigate two distinct federal tax regimes, both administered by the Federal Tax Authority through the EmaraTax portal:

• VAT: 5% standard rate, applied since January 2018. Registration mandatory above AED 375,000 taxable supplies. Voluntary registration above AED 187,500.
• Corporate Tax: 9% on profits above AED 375,000, applied to accounting periods starting on or after 1 June 2023. 0% on profits below the threshold. All taxable persons must register, regardless of profit level, including freezone entities.

On top of these federal regimes sit Economic Substance Regulations (ESR) for entities conducting relevant activities, Ultimate Beneficial Owner (UBO) disclosure obligations, and the Wages Protection System (WPS) for payroll. The compliance load is meaningfully larger than it was five years ago.

VAT filing calendar 2026

VAT returns are filed quarterly (or monthly for larger filers). Returns are due on the 28th day of the month following the end of the tax period. Payment is due on the same date.

Late filing penalties start at AED 1,000 for the first late return and escalate sharply for repeat offences. Late payment penalties are 2% immediately, 4% after seven days, and 1% daily thereafter up to 300%. These compound quickly.

Who has to register for UAE Corporate Tax?

The 2023 Corporate Tax regime fundamentally changed UAE business compliance. Three key points are widely misunderstood:

1. All businesses must register, even freezone

The 9% rate applies above AED 375,000 in taxable income. Below, the rate is 0%. But every taxable person must register with the FTA, regardless of profit. Many UAE SMEs delayed registration assuming "no tax = no registration"; this is wrong, and penalties for late registration apply.

2. Qualifying Free Zone Person (QFZP): 0% on qualifying income only

Freezone entities can qualify for 0% Corporate Tax on "qualifying income" if they meet substance and qualifying-income tests. The headline is appealing; the conditions are real:

• Adequate substance in the freezone (employees, physical presence, expenditure).
• Qualifying income, typically B2B transactions with other freezone or non-resident parties, or specific qualifying activities defined by Cabinet decision.
• De minimis test: non-qualifying income must not exceed AED 5 million or 5% of total revenue, whichever is lower.
• Audited financial statements prepared in accordance with IFRS.
• Transfer-pricing documentation where related-party transactions occur.

Many freezone SMEs assume they automatically benefit from 0%. They don't. The QFZP analysis must be done annually and documented.

3. Small Business Relief (SBR): available until December 2026

For accounting periods where revenue does not exceed AED 3 million, businesses can elect Small Business Relief. The effect is to treat the business as having no taxable income for the period, equivalent to a 0% rate without the substance and qualifying-income tests of QFZP. The election is available for the relief period (currently to 31 December 2026, subject to extension).

For freezone businesses with revenue under AED 3 million, the right strategy is often SBR rather than QFZP: simpler, less substance burden, no transfer-pricing documentation required. Many advisers default to QFZP without considering the SBR alternative, which is why we model both before filing. Setup questions sit with company incorporation across five countries.

Corporate Tax filing dates

The Corporate Tax return is due within nine months of the end of the financial year. Payment is due on the same date.

How does filing through EmaraTax work?

EmaraTax replaced the earlier FTA portal in late 2022 and is now the sole filing channel. The portal handles VAT, Corporate Tax, excise tax and tax-agent administration. A few practical points:

• Tax Agents can file on your behalf through the portal once you grant authorisation. The agent's registration number appears on submissions for full audit trail.
• Refunds for net-input VAT positions are processed within ~20 business days. Larger refunds may trigger desk audit.
• Notifications via EmaraTax are the FTA's primary communication channel. Check it weekly; correspondence has fixed response deadlines.

What else is on the SME compliance calendar

• Economic Substance Notifications: for entities conducting relevant activities. Filed within six months of financial year-end via the Ministry of Finance ESR portal.
• Economic Substance Reports: for the same entities, within twelve months of year-end.
• UBO Register updates: within 15 days of any change in beneficial ownership.
• WPS payroll processing: monthly, through authorised exchange houses or banks.
• Annual statutory accounts: prepared in accordance with IFRS (or IFRS for SMEs where eligible). Required for licence renewals, and the starting point for the Corporate Tax computation.

The UAE went from zero-tax jurisdiction to genuinely complex compliance regime in under a decade. The penalty regime has caught up. Quiet defaults from the pre-VAT era no longer fly.

The bottom line

Three years into Corporate Tax, the regime is mature. Register on time. Document your QFZP or SBR position annually. File quarterly VAT and annual Corporate Tax on the EmaraTax schedule. Track ESR if you conduct relevant activities. Done well, the compliance load is bearable. Done poorly, the penalties scale fast.

Registration deadlines and what missing them costs

Registration is the single most expensive thing to get wrong, because the penalty applies whether or not any tax was ever payable. Corporate Tax registration deadlines were set by reference to the month a licence was issued rather than by one national date, which is why two companies in the same building can have had different deadlines. A business that assumed profits below AED 375,000 meant nothing to do has a fixed administrative penalty waiting for it.

• Corporate Tax registration: required of every taxable person, including free zone entities and companies electing Small Business Relief.
• VAT registration: mandatory once taxable supplies pass AED 375,000 in the preceding twelve months, or where they are expected to in the next thirty days. Voluntary registration is available from AED 187,500.
• Deregistration: also has a deadline, and late deregistration carries its own penalty. Businesses that stop trading routinely forget this one.

The Federal Tax Authority publishes the governing texts in its legislation library, and the penalty schedules sit with them. We check registration status as the first item of any UAE onboarding, before looking at a single transaction.

Small Business Relief or Qualifying Free Zone Person?

For a free zone company under AED 3 million of revenue this is the decision that matters, and the default answer in the market is usually the wrong one. Small Business Relief is an election. Qualifying Free Zone Person status is a test you have to pass every year and document.

Worked example, illustrative rather than a real client. A free zone consultancy bills AED 2.4 million, of which AED 180,000 comes from a mainland client. Under the free zone route that mainland revenue is non-qualifying and has to sit inside the de minimis limit, and the company needs audited accounts and transfer pricing files to defend the position. Electing Small Business Relief instead removes all of that for the period, at the cost of losing it the year revenue passes AED 3 million. The relief is set out in the FTA guidance on Small Business Relief.

What an FTA audit actually asks for

Five things, in our experience, and none of them can be assembled the week the notice arrives. Tax invoices in the required format, including the supplier tax registration number and the VAT amount in dirhams. Evidence supporting zero-rated exports, which means shipping documents rather than an assertion. Reverse charge entries appearing in both the output and input boxes for imported services. A reconciliation from the trial balance to each filed return. And, for free zone entities, the annual working that supports the qualifying income position.

The most common failure we see at takeover is the third one. A UAE company buying software or consultancy from abroad has to self-account for VAT under the reverse charge. Businesses that simply leave it out understate both boxes, which nets to nil on the payment and looks tidy right up to the point somebody reconciles the ledger.

Statutory accounts under IFRS underpin all of it, since the Corporate Tax base starts from accounting profit. That is a real change of habit for businesses that treated the annual accounts as a licence renewal formality.

Getting UAE compliance handled

We file VAT and Corporate Tax through EmaraTax as an authorised agent. The full service sits on accountants for UAE SMEs, with filings through our UAE VAT and Corporate Tax filing service, entity setup through UAE mainland and freezone incorporation, and WPS-compliant payroll through multi-jurisdiction payroll services. Most of our UAE bookkeeping runs in Zoho Books accountants because the FTA report formats are native, with Xero Certified Advisor accountants for groups reporting outside the region. Board reporting runs through monthly management accounts, and groups with a UK parent should read this next to UK R&D tax credits.
