UAE Corporate Tax Deadlines and Penalties 2026: What You Owe and When

Introduction

The Federal Tax Authority publishes its corporate tax deadlines clearly — and applies its penalties just as clearly. If you know the dates, you avoid the fines. If you do not, the fines find you. This page is the consolidated calendar and penalty schedule we use with OPAB clients in 2026, covering registration, filing, payment, transfer pricing, and record-keeping.

Registration Deadlines

Every taxable person must register for corporate tax within a window set by the FTA based on the date the trade licence was issued. Resident juridical persons follow a staggered schedule: a January-February licence issuance generally implied a registration deadline of 31 May 2024, with later licence months following month-by-month. Newly incorporated entities must register within three months of incorporation. Natural persons earning above AED 1 million from business activity must register by 31 March of the year following the year in which the threshold was crossed. The penalty for missing the registration deadline is a fixed AED 10,000.

Filing Deadlines

The corporate tax return is due within nine months of the end of the financial year. For a year ending 31 December 2025, the deadline is 30 September 2026. For a year ending 30 June 2026, the deadline is 31 March 2027. The same nine-month rule applies to the first short-period return for any entity that registered for a part-year. Filing is done through EmaraTax. Late filing carries an AED 500 per month fine for the first 12 months and AED 1,000 per month thereafter, capped at the higher of AED 50,000 or 5% of the unpaid tax.

Payment Deadlines

Corporate tax is paid in a single annual instalment, due on the same date as the return — nine months after year-end. There is no quarterly advance payment regime in the UAE. Late payment is penalised at 14% per annum on the unpaid amount, accruing daily. A delay beyond 12 months can attract a percentage penalty of up to 300% of the tax due in egregious cases of non-payment. Payments are made through GIBAN bank transfer, e-Dirham, or credit card via EmaraTax.

Transfer Pricing Documentation

Taxable persons within the scope of UAE transfer pricing rules must prepare and maintain a Local File and a Master File where their group revenue exceeds defined thresholds, and submit them to the FTA on request within 30 days. The current thresholds are AED 200 million in standalone revenue (for the Local File requirement triggered by qualifying related-party transactions) and AED 3.15 billion in consolidated group revenue (for the Master File requirement). All taxable persons — regardless of size — must complete the transfer pricing disclosure form as part of the corporate tax return, listing material related-party and connected-person transactions. Failing to maintain documentation when required carries an AED 10,000 fine, with additional penalties for non-submission.

Record-Keeping Obligations

Corporate tax records — including financial statements, working papers, supporting invoices, contracts, and transfer pricing files — must be kept for seven years from the end of the relevant tax period. Records may be kept electronically. Failure to maintain adequate records is penalised at AED 10,000 for the first violation and AED 20,000 for repeat violations within 24 months. The FTA can also disallow expense deductions when records are missing, increasing the corporate tax liability significantly.

Voluntary Disclosures

If you discover an error in a previously filed return, you must submit a voluntary disclosure within 20 business days of discovery for material errors. Voluntary disclosures attract a fixed AED 1,000 fine plus a percentage penalty on the unpaid tax, which is significantly lower than the penalty if the FTA finds the error first. The voluntary disclosure window is one of the most under-used compliance tools in the UAE — fixing your own error is almost always cheaper than letting it find you.

Penalty Reduction and Waivers

The FTA operates a penalty waiver framework where, in defined circumstances, penalties may be reduced or waived if the taxpayer can demonstrate reasonable cause and full cooperation. The window for requesting a waiver is short, and the application must be supported by evidence — typically a memo from a UAE-licensed tax adviser. OPAB has secured several waivers for clients in 2025 and 2026; the pattern is the same in every case: act fast, prepare the file thoroughly, and engage with the FTA respectfully.
