The Challenge
"Everyone keeps saying Corporate Tax started in June 2023, but my accountant says my company's start date is different. My financial year runs January to December — so when does it actually apply to me? I don't want to register too early or too late and end up penalised either way."
This confusion is one of the most common questions we hear from UAE business owners, and it’s a fair one — Corporate Tax didn’t switch on for every company on the same day. A Dubai-based trading LLC with a January-December financial year and a consultancy with a July-June year genuinely fall under different effective dates, even though both are UAE businesses subject to the same law. The Federal Decree-Law No. 47 of 2022 sets the framework, but the actual date your business starts owing Corporate Tax is tied to your own accounting calendar, not a single fixed day for the whole country.
Our Approach
- Your financial year sets the date — Corporate Tax applies from the start of your first financial year that begins on or after 1 June 2023, so a business with a calendar-year (Jan-Dec) accounting period became subject to CT from 1 January 2024, while one with a July-June year became subject to it from 1 July 2023.
- 9% above AED 375,000, 0% below — once your tax period applies, taxable profit up to AED 375,000 is taxed at 0%, and profit above that threshold is taxed at 9%; Small Business Relief can reduce this further for businesses with revenue at or below AED 3 million.
- Registration comes first, filing comes later — juridical persons (companies, including most free zone and mainland entities) must register with the FTA via EmaraTax regardless of profit level, and the first Corporate Tax return is generally due within 9 months of the end of that first tax period.
- We start by confirming a client's exact financial year end, because that single date determines the effective date, the registration deadline, and the first filing deadline together — get it wrong and every downstream date is wrong too.
The Result
Once we’ve confirmed your financial year and effective date, we map out your registration deadline, tax period, and first return due date in one timeline, so there’s no guesswork about whether a given transaction falls inside or outside the taxable period. For a business we’re already advising, this also means checking whether the AED 10,000 late-registration penalty waiver applies — available where the first return is filed within 7 months of the end of the first tax period (for December 2025 year-ends, that’s by 31 July 2026). Businesses that get their effective date right from the outset avoid both premature compliance costs and last-minute penalty exposure.
The Takeaway
"UAE Corporate Tax applies from the start of your first financial year beginning on or after 1 June 2023 — the date is set by your own accounting year, not a single fixed calendar date for every business."
