UAE Corporate Tax Filing: The 2026 Compliance Guide for Business Owners
For most of its history, the UAE was effectively a tax-free place to run a business. That changed with the introduction of federal corporate tax, and 2026 is the year a lot of business owners are dealing with UAE corporate tax filing for the first time — new obligations, tighter Federal Tax Authority enforcement, and a valuable relief measure that's about to disappear. If you run a company in Dubai, Abu Dhabi, or any of the free zones, this guide explains exactly what you owe, when you owe it, and what's changing.
UAE corporate tax: the 9% rate explained
The UAE's federal corporate tax was introduced under Federal Decree-Law No. 47 of 2022 and applies to financial years starting on or after 1 June 2023. The headline structure is straightforward:
0% on taxable income up to AED 375,000
9% on taxable income above AED 375,000
That AED 375,000 figure is a zero-rate band, not an exemption from the system. This is the single most misunderstood point in UAE corporate tax: even if your profit sits entirely within the 0% band, you must still register, file a return, and comply. Being below the threshold does not make you invisible to the Federal Tax Authority (FTA) — it just means your calculated tax happens to be zero.
Taxable income starts from your company's net accounting profit, then applies the adjustments the law allows — deductible expenses, certain exemptions, and reliefs. A business with AED 600,000 in revenue but AED 300,000 in genuine allowable expenses has AED 300,000 in taxable income, which sits below the threshold. But that only works if your bookkeeping actually supports those expense claims. Poor records don't protect you from tax — they usually mean you pay more of it.
Registration is mandatory — and the deadline has teeth
Every taxable company in the UAE must register for corporate tax and obtain a Corporate Tax Registration Number through the FTA's EmaraTax portal. There is no minimum revenue threshold for a company to register — a newly incorporated business with zero revenue still has to.
For companies incorporated from March 2024 onwards, registration must be completed within three months of incorporation. Miss that window and you're looking at a fixed administrative penalty of AED 10,000. If you're not yet registered, treat it as urgent — the process typically takes a few weeks including any FTA follow-up queries.
When do you file? UAE corporate tax filing deadlines
Corporate tax returns are filed annually through the FTA's EmaraTax portal. The return — and any payment due — is due within nine months of the end of your company's financial year.
So a company with a 31 December year-end must file and pay by 30 September of the following year. There are currently no advance payments or quarterly instalments required for most UAE businesses, which is a relief compared with many other countries — but it also means the full liability lands in one payment, so plan your cash flow accordingly.
Small Business Relief — and why 2026 is the year it matters
Small Business Relief (SBR) is the most valuable transitional measure the UAE has offered smaller companies. If your revenue is AED 3 million or less — in both the current period and all previous periods — you can elect to be treated as having zero taxable income for that period. In plain terms: no corporate tax liability.
Two things to know. First, it isn't automatic — you have to actively elect it when you file. Second, and this is the big one: SBR is only available for tax periods ending on or before 31 December 2026.
That's a hard stop. From 1 January 2027, the standard rules apply to everyone, regardless of revenue. A business earning AED 800,000 in taxable profit that pays nothing today would owe around AED 38,250 a year once relief ends. If you've been relying on SBR, the months before that deadline are your runway to get proper books, a compliant chart of accounts, and clean records in place — not a reason to wait.
There's also a catch worth naming: electing SBR means you can't carry forward tax losses for that period, and you must still register, keep books, and file a return. Relief from tax is not relief from compliance.
VAT: a separate obligation you can't ignore
Corporate tax and VAT are two different taxes with two different registrations, and it's common to owe one without the other. VAT is a 5% consumption tax on taxable goods and services, introduced back in 2018.
The registration thresholds:
Mandatory registration once your taxable supplies and imports exceed AED 375,000 over the previous 12 months (or you expect to exceed it in the next 30 days)
Voluntary registration available once supplies or expenses exceed AED 187,500
A trap to watch: the AED 375,000 figure appears in both taxes but means different things. You can be below the VAT registration threshold and still have a corporate tax registration obligation, because the two are measured differently. Getting both registrations right — and filing the right returns for each — is where a lot of businesses slip. Our UAE VAT service handles registration and quarterly returns end to end.
One 2026 change worth flagging for anyone carrying VAT credits: excess input VAT can no longer be carried forward indefinitely. From 1 January 2026 the carry-forward is capped at five years, after which unused credits expire. If you've been sitting on old credit balances, review them now rather than assuming they're safe.
Free zone companies: the 0% rate isn't automatic
If you're in a free zone like DMCC, JAFZA, IFZA, or Meydan, you may qualify for a 0% rate as a Qualifying Free Zone Person (QFZP) — but only on income the law classifies as "qualifying income," and only if you meet every condition. That includes maintaining adequate substance in the free zone, meeting the de minimis limits on non-qualifying revenue, and preparing audited financial statements.
Many free zone owners assume their 0% status is guaranteed. It isn't — it's conditional, and the qualifying-income rules were refreshed in 2025. Income from mainland UAE customers is generally non-qualifying. If free zone status is central to your tax position, it's worth having someone confirm you actually meet the conditions rather than assuming. If you're still deciding on structure, our UAE company formation guide walks through free zone versus mainland.
Frequently asked questions
Does my UAE company have to register for corporate tax even if it makes no profit?
Yes. Corporate tax registration is mandatory for every taxable company regardless of profit or revenue. A newly incorporated company with zero income still has to register with the FTA through EmaraTax, usually within three months of incorporation. Being below the AED 375,000 zero-rate band or qualifying for Small Business Relief doesn't remove the obligation to register and file — it only affects how much tax you actually pay. Late registration carries an AED 10,000 penalty, so it's worth handling early.
What is the VAT registration threshold in the UAE?
Mandatory VAT registration applies once your taxable supplies and imports exceed AED 375,000 over the previous 12 months, or when you expect to cross that figure within the next 30 days. Voluntary registration is available at a lower level — once your taxable supplies or expenses exceed AED 187,500. Registration is done through the FTA's EmaraTax portal. Note that VAT and corporate tax are separate: being registered for one doesn't register you for the other.
When does Small Business Relief end in the UAE?
Small Business Relief is available only for tax periods ending on or before 31 December 2026. From 1 January 2027, the standard corporate tax rules apply to all businesses regardless of revenue. If your company qualifies now (revenue of AED 3 million or less), you can elect relief and pay no corporate tax for eligible periods — but you should use the time before the deadline to get your bookkeeping and records into proper shape, because full compliance kicks in straight after.
When is my UAE corporate tax return due?
Your corporate tax return and any payment are due within nine months of the end of your financial year. For a company with a 31 December year-end, that means a 30 September deadline the following year. Filing is done annually through EmaraTax, and for most businesses there are no quarterly instalments — the full amount is due at filing. Deadlines and rules can change, so confirm your specific dates on the FTA portal (tax.gov.ae) or with our team.
