This checklist reflects UAE corporate tax rules and FTA guidance as of October 2026. Penalty amounts and deadlines change through Cabinet and Ministerial Decisions, so confirm the current position on tax.gov.ae or with a registered tax agent before you file.
UAE corporate tax is now in its third year, and the Federal Tax Authority (FTA) has moved from education to enforcement. For most SMEs the tax itself is manageable — 0% on taxable income up to AED 375,000 and 9% above it — but the compliance work around it is where businesses get caught: missed registrations, late returns, weak records and penalties that add up month after month.
Use this checklist to see what corporate tax compliance actually involves for a UAE SME, what is due when, and which changes matter in 2026.
Every taxable person must hold a corporate tax registration and a Tax Registration Number (TRN) for CT — including free zone companies, businesses below AED 375,000 of profit and companies that will claim Small Business Relief. Registration is done on EmaraTax, the FTA portal.
Newly incorporated companies generally have three months from incorporation to register. The penalty for registering late is a fixed AED 10,000. In 2025 the FTA introduced a waiver of this penalty for businesses that file their first corporate tax return within seven months of the end of their first tax period — check on EmaraTax whether the waiver still applies to you.
Your corporate tax period normally follows your financial year. Two dates drive everything:
| Obligation | Deadline |
|---|---|
| Corporate tax return (filed on EmaraTax) | Within 9 months of the end of the tax period |
| Corporate tax payment | Same date as the return — within 9 months |
| Example: year ending 31 December 2025 | Return and payment due by 30 September 2026 |
| Example: year ending 31 March 2026 | Return and payment due by 31 December 2026 |
Put both dates in your calendar the day your financial year starts. Most late-filing penalties come from businesses that knew the rule but left the accounts until the final month.
Corporate tax is calculated from your accounting profit, so your books are your tax records. The FTA expects:
If your accounts live in spreadsheets, this is the single biggest compliance risk. An accounting system that posts entries from source documents and keeps them locked gives you the audit trail automatically.
ETaxFlow posts your entries from invoices, calculates your 9% CT position each period and flags Small Business Relief eligibility.
Audited accounts are required for corporate tax purposes if your revenue exceeds AED 50 million in the tax period, or if you are a Qualifying Free Zone Person claiming the 0% rate — whatever your size. Line up your auditor early; audit timetables are the most common reason returns slip past the nine-month deadline.
If your revenue is AED 3 million or less, you can elect Small Business Relief and be treated as having no taxable income. The relief currently covers tax periods ending on or before 31 December 2026, so for many businesses the 2026 financial year is the last one it applies to. Plan now for paying 9% on profits above AED 375,000 from 2027. Our Small Business Relief guide explains the conditions and the anti-fragmentation rules.
Transactions with related parties and connected persons (shareholders, directors, group companies) must be at arm’s length. Depending on the values involved you may need to file a transfer pricing disclosure form with your return, and large groups must keep a master file and local file. Keep written agreements for management fees, intercompany loans and shareholder salaries.
| Failure | Penalty |
|---|---|
| Late corporate tax registration | AED 10,000 (fixed) |
| Late filing of the CT return | AED 500 per month for the first 12 months, then AED 1,000 per month |
| Late payment of tax due | Charged monthly on the unpaid tax — revised from 14 April 2026 by Cabinet Decision 129 of 2025 (see below) |
| Errors found by the FTA before you disclose them | Higher penalties than voluntary disclosure — correct mistakes yourself first |
What changed in 2026: Cabinet Decision 129 of 2025, effective 14 April 2026, overhauled the UAE’s tax penalty framework. Late-payment penalties moved to an annualised rate (reported as 14% per year, charged monthly) and the penalties for errors now reward voluntary disclosure over waiting for an audit. Check the FTA’s current penalty table for the exact rates that apply to your return.
Corporate tax compliance and VAT compliance are converging. The UAE’s mandatory e-invoicing system starts with businesses with revenue of AED 50 million or more from 1 January 2027, followed by other businesses from 1 July 2027, all through FTA-accredited service providers. Clean, structured invoice data now will make both e-invoicing and corporate tax far easier. Read our UAE e-invoicing guide for the timeline.
Yes. Registration is required for every taxable person regardless of profit. Profit up to AED 375,000 is taxed at 0%, but you must still register, keep records and file an annual corporate tax return on EmaraTax.
The corporate tax return and any tax payable are due within 9 months of the end of your tax period. For a financial year ending 31 December 2025, the deadline is 30 September 2026.
The penalty for late corporate tax registration is a fixed AED 10,000. The FTA has offered a waiver for businesses that file their first return within seven months of the end of their first tax period; check EmaraTax to see whether it applies to you.
Late filing of a corporate tax return is penalised at AED 500 per month for the first 12 months and AED 1,000 per month after that, in addition to any late-payment penalty on unpaid tax.
Corporate tax records, including financial statements and supporting documents, must be kept for seven years after the end of the tax period they relate to.
Small Business Relief currently applies to tax periods ending on or before 31 December 2026 for businesses with revenue of AED 3 million or less, so 2026 is the last confirmed year for most businesses.
Corporate tax compliance software keeps your books in an auditable form, calculates your taxable income and 9% corporate tax each period, tracks Small Business Relief eligibility and prepares the figures for your EmaraTax return.
