Quick Answer
Yes. Corporate Tax return filing is mandatory for almost every taxable person in the UAE, including companies that made no profit and free zone companies taxed at 0%. There is no “zero income, no filing” exemption. Filing is waived only for a named list of exempt persons under Article 4 of Federal Decree-Law No. 47 of 2022, such as government entities and qualifying pension funds. Everyone else, from a mainland LLC with AED 50,000 in revenue to a Qualifying Free Zone Person, must submit a return within 9 months of tax period end, or face an AED 500 monthly penalty rising to AED 1,000 a month after 12 months.

Who Actually Has To File a Corporate Tax Return
The UAE Corporate Tax regime taxes profit above AED 375,000 at 9%, with the first AED 375,000 taxed at 0%. That 0% band causes the confusion: business owners assume a 0% tax bill means no filing obligation. It does not. Filing and paying are separate obligations, and a return sitting entirely inside the 0% bracket still gets filed, declaring AED 0 payable.
The following categories are all required to register with the Federal Tax Authority (FTA) and file a Corporate Tax return for every tax period, regardless of whether tax is actually owed:
- Mainland UAE companies of any size, including those with zero or negative taxable income for the period
- Free zone companies, whether or not they qualify as a Qualifying Free Zone Person taxed at 0% on qualifying income
- Foreign companies that are effectively managed and controlled in the UAE, or that have a UAE permanent establishment
- Natural persons (sole proprietors and individual partners) whose UAE business turnover exceeds AED 1 million in a calendar year
- Businesses that have elected for Small Business Relief (filing is simplified, not removed)
The Exempt Persons Who Do Not Need to File
A narrow, named list under Article 4 of the Corporate Tax Law sits outside the filing net, not a general carve-out for “small” or “non-profitable” businesses.
| Exempt category | Filing position |
|---|---|
| Government entities | Automatically exempt, no registration or filing required |
| Government-controlled entities (specified activities only) | Automatically exempt, no registration or filing required |
| Extractive businesses and non-extractive natural resource businesses | Exempt only if conditions are met and notified to the FTA; otherwise must register and file |
| Qualifying Public Benefit Entities | Must apply to the FTA and be listed by Cabinet Decision to keep exempt status; ongoing conditions apply |
| Qualifying Investment Funds | Must meet conditions each period; loses exemption (and files as a normal taxable person) in a period it fails to qualify |
| Public or private pension and social security funds | Exempt if conditions in the Corporate Tax Law and implementing decisions are met |
| Wholly-owned UAE subsidiaries of an exempt person, undertaking the same exempt activity | Exempt if specific ownership and activity conditions are met |
Outside the two automatic categories, exemption is conditional. A Qualifying Investment Fund or Qualifying Public Benefit Entity that slips outside its conditions in a given period becomes a normal filer for that period.
Filing Deadlines Are Period-Specific, Not One Fixed Date
There is no single UAE-wide filing date. The deadline is 9 months after the end of each taxable person’s own tax period, and tax periods follow each company’s financial year, which does not have to be the calendar year. Two companies incorporated the same week can have entirely different filing deadlines if their financial years end on different dates.
| Financial year-end (tax period end) | Filing and payment deadline (9 months later) |
|---|---|
| 31 December | 30 September of the following year |
| 31 March | 31 December of the same year |
| 30 June | 31 March of the following year |
| 30 September | 30 June of the following year |
Worked example: a mainland company with a financial year of 1 January to 31 December 2026 must file and settle any tax due by 30 September 2027. A free zone entity with a 1 April 2026 to 31 March 2027 financial year has until 31 December 2027 instead, despite both covering a broadly similar period of activity. Always check the tax period confirmed on your own FTA registration, not a generic calendar date.
This filing deadline is a separate matter from the deadline to first register for Corporate Tax, which runs off your trade licence issue date rather than your tax period. See our guide to Corporate Tax registration and our breakdown of registration timelines by licence issuance for that separate obligation.
Small Business Relief Does Not Remove the Filing Requirement
Small Business Relief lets a resident taxable person with revenue at or below AED 3,000,000 in the relevant and prior tax periods elect to be treated as having no taxable income for that period, so no 9% Corporate Tax applies. The Ministry of Finance confirmed in August 2026 that this relief, and the AED 3,000,000 revenue threshold, is extended through tax periods ending on or before 31 December 2029.
The relief changes the tax computation, not the filing obligation. A business that elects Small Business Relief still registers, still files a return by the same 9-month deadline, and still declares the election in that return. Skipping the filing on the assumption that “0% relief means nothing to file” triggers the same late-filing penalty as any other missed return. Businesses that fall outside the relief still convert accounting profit into taxable income using the standard adjustments; see our guide to computing Corporate Tax returns for that calculation.
What Missing the Deadline Actually Costs
Late Corporate Tax return filing carries an administrative penalty of AED 500 per month (or part of a month) for the first 12 months of default, rising to AED 1,000 per month from month 13 onward, on top of any 9% tax due on unfiled profit plus late payment penalties. A company that files a return 14 months late, with tax due, is exposed to AED 6,000 in filing penalties alone (12 months at AED 500 plus 2 months at AED 1,000) before payment penalties are added. This is only the filing-delay penalty; the full penalty schedule for registration, filing, payment and record-keeping failures is covered in our Corporate Tax penalty guide.
Frequently Asked Questions
Do I need to file a Corporate Tax return if my company made a loss?
Yes. A loss-making period still requires a return. Filing is how the FTA records the loss, and how that loss becomes available to carry forward against future taxable profit.
Does a free zone company taxed at 0% still have to file a return?
Yes. Qualifying Free Zone Person status affects the tax rate applied to qualifying income, not whether a return is due. Every free zone company registered for Corporate Tax must file.
Is there a fixed date every UAE company must file by, like 30 September?
No. 30 September only applies to a company whose financial year ends on 31 December. The rule is 9 months after your own tax period ends, which can fall on a different date for a different financial year-end.
Which businesses are the only ones excused from filing altogether?
Government entities and government-controlled entities carrying out only specified activities are automatically excused. Every other exempt category, such as qualifying public benefit entities, qualifying investment funds, and pension funds, must meet ongoing conditions to keep that exemption; failing them puts a business back into normal filing.
