The 30 September 2026 Deadline: How It Works

Under Federal Decree-Law No. 47 of 2022 (the Corporate Tax Law), every taxable person must file a corporate tax return and settle the full tax liability within nine months of the end of the tax period. For the large majority of UAE companies that use the calendar year, the financial year ended 31 December 2025 — so the return and the payment are both due by 30 September 2026. There is no separate, later payment window and no provisional instalment system: one date covers both obligations. Different year-ends shift the date under the same nine-month rule. A financial year ending 31 March 2026 files by 31 December 2026; a year ending 30 June 2026 files by 31 March 2027. The Federal Tax Authority (FTA) does not grant routine extensions, and filing is mandatory even when no tax is due — loss-making companies, companies below the AED 375,000 threshold and businesses electing small business relief must all submit a return through the EmaraTax portal. Because penalties are computed monthly from the day after the deadline, filing on 1 October 2026 already triggers the first month's fine. Treat 30 September 2026 as a hard cut-off, and verify the tax period registered against your entity in EmaraTax before you plan the filing — a mismatched period is a common cause of accidental lateness.

Penalty Schedule with Worked Example: AED 100,000 Tax, 4 Months Late

Cabinet Decision No. 75 of 2023 (in force since 1 August 2023) sets the administrative penalties. Late filing costs AED 500 for each month, or part of a month, for the first twelve months, rising to AED 1,000 per month from the thirteenth month onward. Late payment is charged separately at 14% per annum, applied monthly to the unpaid tax from the day after the due date, per current guidance. Worked example: a company owes AED 100,000 for FY 2025 (roughly AED 1,486,111 of taxable income — 9% of the amount above AED 375,000). It files and pays on 31 January 2027, four months after the 30 September 2026 deadline: - Late-filing penalty: 4 months × AED 500 = AED 2,000 - Late-payment penalty: AED 100,000 × 14% × 4/12 = AED 4,667 - Total penalties: about AED 6,667, on top of the AED 100,000 tax itself Stretch the delay to thirteen months and the numbers jump: filing penalties reach AED 7,000 (12 × AED 500 + 1 × AED 1,000) and the payment penalty about AED 15,167 (thirteen monthly charges of AED 1,166.67) — roughly AED 22,167 combined, more than 22% of the tax. Because part-months count as full months, even a one-day slip is billed as an entire month.

Registration Traps: The AED 10,000 Penalty

The most common penalty in practice is not for late filing but for late registration. Cabinet Decision No. 10 of 2024 added a fixed AED 10,000 fine for failing to submit the corporate tax registration application on time, with deadlines set by FTA Decision No. 3 of 2024 according to the month the trade licence was issued. Three traps catch businesses. First, registration is required even with zero profit — dormant entities holding a licence and free zone companies included. Second, natural persons (sole establishments and freelancers) must register once business turnover exceeds AED 1 million in a calendar year; many individuals do not realise the regime reaches them. Third, ceasing business triggers its own deregistration deadlines. The good news: under the FTA's penalty-waiver initiative, the AED 10,000 fine is waived — or refunded if already paid — provided the first tax return (or annual declaration) is submitted within seven months of the end of the first tax period, two months earlier than the standard nine. The FTA reported more than 68,600 beneficiaries by May 2026, with the total expected to exceed 91,000. Per current guidance the waiver applies only to the first tax period, so verify eligibility on tax.gov.ae before relying on it. If your first tax period ended 31 December 2025, the seven-month waiver window runs until 31 July 2026 — still open at the time of writing, so filing the first return immediately can still secure the AED 10,000 waiver. Check the exact date against your own period end (seven months after it) before relying on this.

Small Business Relief: The AED 3 Million Election

Small business relief under Ministerial Decision No. 73 of 2023 lets a resident taxable person be treated as having no taxable income for a tax period if revenue is AED 3,000,000 or less in that period and in every previous tax period beginning on or after 1 June 2023. Cross the threshold once and the relief is gone for that period and all later ones. Key mechanics to get right on the FY-2025 return: - It is an election made inside the tax return — it is not applied automatically. - You must still register, still file by 30 September 2026 and still keep records; the relief removes the tax computation, not the compliance obligations. A small business that files late accrues the same AED 500 monthly fine. - The relief is only available for tax periods ending on or before 31 December 2026, so the FY-2025 return due this September and the FY-2026 return are the last two calendar-year periods that can use it, per current guidance. Exclusions: qualifying free zone persons and members of multinational enterprise groups with consolidated revenue above EUR 750 million cannot elect. Businesses using the relief also cannot deduct expenses or carry forward tax losses arising in those periods, so model both routes before electing — for a company with large losses, filing normally may be worth more.

Free Zone 0% Rate: Qualifying Income Conditions

Free zone companies are not automatically at 0%. Article 18 of the Corporate Tax Law, with Cabinet Decision No. 100 of 2023 and Ministerial Decision No. 265 of 2023, creates the Qualifying Free Zone Person (QFZP) regime: 0% on qualifying income and 9% on everything else — and, importantly, the AED 375,000 zero band does not apply to a QFZP's taxable income. Qualifying income broadly covers listed qualifying activities — manufacturing and processing, commodity trading, fund and wealth management, reinsurance, ship operation, treasury services to related parties, aircraft financing and leasing, logistics, and distribution from a designated zone — plus transactions with other free zone persons. To keep QFZP status a company must maintain adequate substance in the free zone (qualified staff, assets, operating expenditure), prepare audited financial statements, comply with transfer pricing rules and documentation, and not elect into the standard regime. Non-qualifying revenue must stay within the de minimis limit: the lower of 5% of total revenue or AED 5 million. Breach any condition and QFZP status is lost for the current tax period and the following four, with all income taxed at 9%. QFZPs also cannot use small business relief. This is a summary only — the conditions run to dozens of pages, so verify your position against the FTA's Free Zone Persons guide (CTGFZP1) before filing.

Compliance Checklist Before 30 September 2026

Work through this list well before the deadline — several items have their own lead times: - Confirm your registration and Tax Registration Number (TRN) in EmaraTax, and check the tax period on record matches your financial year. - Determine whether audited financial statements are mandatory: per current guidance they are required for taxable persons with revenue above AED 50 million and for all qualifying free zone persons (Ministerial Decision No. 82 of 2023). - Apply the rate bands from Cabinet Decision No. 116 of 2022: 0% on taxable income up to AED 375,000 and 9% above it. - Decide elections before submission: small business relief (if revenue is AED 3 million or below), the realisation basis, and transfer pricing disclosures if you have material related-party transactions. - Pay early via your GIBAN in EmaraTax — bank transfers can take days to clear, and the 14% per annum late-payment clock starts the day after the deadline regardless of intent. - Retain records and supporting documents for seven years. The corporate tax regime is new and parameters are still being refined through ministerial decisions, so verify each figure on tax.gov.ae before filing — and if a penalty has already been assessed, check whether a waiver or reconsideration request applies before paying.
