This UAE corporate tax 2027 checklist is for business owners and finance teams planning the year ahead — UAE companies, free-zone businesses and individuals running a business — whose financial year falls in 2027. UAE Corporate Tax has applied to financial years beginning on or after 1 June 2023, so by 2027 the question is no longer whether the tax applies, but whether every step is still done correctly, on time, and with figures that are current. Work through the items below and confirm the numbers with the Federal Tax Authority before you file.
What this UAE corporate tax 2027 checklist covers
This UAE corporate tax 2027 checklist covers eight recurring obligations, from registration to the nine-month filing deadline. None of them is new for 2027, but each carries a figure or a date worth re-confirming rather than copying forward from last year’s return.
| Obligation | What 2027 requires |
|---|---|
| Register | Every taxable person holds a Corporate Tax Registration Number via EmaraTax |
| Rate | 0% up to AED 375,000 of taxable income; 9% on the portion above |
| File & pay | Within nine months of your financial year-end (a 31 Dec 2026 year is due 30 Sep 2027) |
| Free zone | 0% only on qualifying income, with audited accounts |
| Small Business Relief | Revenue not above AED 3 million — confirm it still applies to your 2027 year |
| Records | Retain every document that supports your return |
Who must register for UAE corporate tax in 2027?
Every taxable person must register for UAE corporate tax and hold a Corporate Tax Registration Number, free-zone companies included.
The Ministry of Finance confirms that UAE juridical persons, non-resident entities with a UAE permanent establishment, and individuals conducting a business in the UAE are all within scope. If you registered in an earlier year there is nothing to repeat for 2027 — but a new company, a new branch, or an individual who has only now crossed into business activity still registers through EmaraTax. Our UAE accounting and corporate tax team handles registration and the annual return together.
What are the UAE corporate tax rates for 2027?
The UAE corporate tax rate for 2027 is 0% on taxable income up to AED 375,000 and 9% on the portion above it.
These bands have applied since the tax began and, on current law, carry into 2027; they are set in the Federal Tax Authority corporate tax guidance, so re-confirm them on tax.gov.ae before you compute a liability. Taxable income is accounting profit adjusted for the Corporate Tax Law’s specific additions and deductions — not revenue — so a business can sit under AED 375,000 of taxable income while turning over much more.
When is the 2027 filing and payment deadline?
The corporate tax return and any tax due are both filed within nine months of your financial year-end. A 31 December 2026 year is due by 30 September 2027.
A financial year ending 31 December 2027 files by 30 September 2028. The nine-month rule covers the return and the payment together, so a late payment is not a separate, softer deadline. A loss year or a nil-liability year is still filed — the obligation does not depend on owing tax.
Does a free zone company still pay 0% in 2027?
A free-zone company keeps the 0% rate in 2027 only on its qualifying income, and only while it meets every qualifying free zone person condition.
Those conditions include adequate substance, qualifying activities, the de minimis limit on non-qualifying revenue, transfer-pricing documentation, and audited financial statements. The 0% is not attached to the trade licence; it is earned each year, and income outside the qualifying definition is taxed at 9%. Because audited accounts are a hard condition, arrange your audit and assurance early rather than in the filing month.
Is Small Business Relief still available in 2027?
Small Business Relief lets a resident person with revenue of AED 3 million or less elect to be treated as having no taxable income — but it runs only up to a cut-off date set by Ministerial Decision, and whether that still reaches a 2027 financial year is the thing to confirm before you rely on it.
The AED 3 million test applies to the current and every previous tax period. The Federal Tax Authority confirms that even an eligible business must still register and still submit a simplified return within the nine-month deadline. Confirm on tax.gov.ae whether the relief still covers your 2027 financial year before assuming a nil liability.
What records must you keep for 2027?
A taxable person keeps every document and record that supports its corporate tax return, and prepares financial statements on the accounting standards the law accepts.
The approved accounting standards are set by Ministerial Decision, not chosen freely. Keep the underlying books, contracts, invoices and the transfer-pricing file for the retention period the Corporate Tax Law requires, and confirm the current period on tax.gov.ae. Clean, continuous accounting and bookkeeping through the year is what makes those records defensible if the authority asks to see them.
Does the domestic minimum top-up tax affect you in 2027?
The domestic minimum top-up tax reaches only very large groups in 2027, not ordinary UAE businesses.
The Ministry of Finance states it applies to members of multinational groups with annual global revenues of €750 million or more in at least two of the four preceding financial years, for financial years starting on or after 1 January 2025 — so it is live for 2027, but only for groups of that size. If your group is below that threshold, the standard 0% and 9% corporate tax is the whole of your 2027 position.
Little of this changes shape in 2027. The work is confirming that the figures, the dates and the reliefs are still the ones that apply to your year, and filing before the nine-month clock runs out. Talk to our UAE tax team →
