The UAE introduced a 9% corporate tax in June 2023. Since then, thousands of businesses across the Emirates have been trying to understand what it means for them — what they owe, when to file, and how to stay on the right side of the Federal Tax Authority (FTA).

The honest truth is, compliance is not just about filing a return once a year. It starts from the day you register as a taxable person, runs through how you maintain your books and records, and ends only when the FTA closes the assessment window — which can be years after the return is filed.

At Fincirc, we help businesses across Dubai, Abu Dhabi, Sharjah, and the wider UAE take this entire process off their plate. From FTA registration to return filing and ongoing compliance, we make sure nothing is missed — and nothing triggers a penalty.

Who Does UAE Corporate Tax Apply To?

Under the UAE Corporate Tax Law (Federal Decree-Law No. 47 of 2022), corporate tax applies to:

  1. All UAE-incorporated businesses (mainland and free zone companies)
  2. Foreign companies that have a permanent establishment in the UAE
  3. Individuals who carry on a business or business activity in the UAE and earn income above AED 1 million in a calendar year

Free zone companies are in a different position. Those that qualify as Qualifying Free Zone Persons (QFZPs) can benefit from a 0% corporate tax rate on qualifying income. But this only applies if they meet strict conditions around substance, income type, and arm’s length dealings with non-free zone parties. Getting this wrong is one of the most common — and costly — mistakes we see.

What Corporate Tax Compliance Actually Involves

Many businesses think corporate tax compliance means filing one return per year. The reality is a multi-step process that runs throughout the financial year:

  1. FTA Registration — Every taxable person must register with the FTA and obtain a Tax Registration Number (TRN). Deadlines vary based on your financial year-end. Late registration carries a penalty of AED 10,000.
  2. Accounting Setup — Your financial statements must be prepared under an acceptable accounting standard (IFRS is the most common in the UAE). Your chart of accounts and transaction categorisation need to align with UAE CT law requirements.
  3. Preparing Financial Statements — Audited or unaudited financials (depending on your revenue threshold) form the base of your tax return.
  4. Filing the Corporate Tax Return — The return must be filed within 9 months of your financial year-end. For most businesses on a calendar year, the deadline is 30 September.
  5. Tax Payment — Any tax due must be paid by the same deadline as the return. Late payment carries a 2% monthly penalty on the outstanding amount.
  6. Record Keeping — All records supporting your tax return must be kept for a minimum of 7 years. This includes contracts, invoices, bank statements, and intercompany agreements.

Common Mistakes Businesses Make With UAE Corporate Tax

In our work with businesses across the UAE, these are the mistakes we see most often:

  • Registering late because of confusion about the deadline — the FTA calculates your deadline from your financial year-end, not the date you started trading
  • Selecting the wrong financial year during registration — this affects your first filing deadline and can be difficult to change
  • Claiming small business relief without checking eligibility — you must elect this in the return, and it is not automatic
  • Missing related party disclosures — if you transact with shareholders, directors, or group companies, these must be disclosed and priced on arm’s length terms
  • Claiming expenses that are not deductible under UAE CT law — entertainment costs, fines, and payments to related parties without documentation are commonly disallowed
  • Not understanding the difference between exempt income and non-taxable income — getting this wrong can either overstate or understate your tax liability

FTA Penalties for Corporate Tax Non-Compliance

The FTA has a clear penalty framework for corporate tax non-compliance. These are not theoretical — they apply from the first day of default:

  • AED 10,000 for failure to register within the required deadline
  • AED 1,000 per month (up to AED 10,000) for failure to keep proper records
  • 2% of unpaid tax per month for late payment
  • AED 500 per month for failure to file the return on time (first 12 months), then AED 1,000 per month thereafter
  • Additional penalties for understatement of taxable income where the difference exceeds AED 50,000

These penalties are in addition to any tax that becomes payable after an FTA audit. The best way to avoid them is to have the right processes in place from the start.

Frequently Asked Questions

  1. When is the UAE corporate tax return due?

The return must be filed within 9 months of the end of your tax period. For businesses on a calendar year (January to December), the deadline is 30 September of the following year. Tax payment is due on the same date.

2. Is there a small business relief in the UAE?

Yes. Businesses with revenue of AED 3 million or below can elect small business relief, which treats their taxable income as zero for that tax period. This must be elected in the tax return — it is not applied automatically. The relief is available for tax periods ending before 31 December 2026.

3. Do free zone companies pay corporate tax in UAE?

Free zone companies are subject to corporate tax but may qualify for a 0% rate on qualifying income if they meet the conditions for Qualifying Free Zone Person (QFZP) status. This includes having adequate substance in the UAE, earning qualifying income, and not making elections that exclude them from QFZP treatment.

4. What is the penalty for late corporate tax filing in UAE?

The FTA charges AED 500 per month for the first 12 months of late filing, and AED 1,000 per month thereafter. If tax is also unpaid, a 2% monthly penalty applies to the outstanding amount. These penalties are separate and both apply if a return is both late and has tax due.

5. Do I need an audit for UAE corporate tax purposes?

Businesses with revenue above AED 50 million are required to prepare audited financial statements. Below this threshold, unaudited statements are acceptable. However, the FTA can still request supporting documentation during an audit — so maintaining accurate records is essential regardless of size.
