How to determine your Corporate Tax period in the UAE: a guide for business

With the introduction of Corporate Tax in the UAE, businesses have faced a practical question: how do you correctly determine the period you need to report to the Federal Tax Authority (FTA) for? This "tax period" is the basis for calculating your obligations and filing your return, and getting it wrong can cost you a fine.

What is a tax period

A tax period is the span of time after which a company must prepare and file a tax return and pay the calculated Corporate Tax amount. In the UAE, the tax period is directly tied to the company's financial year, which is convenient — it keeps accounting and tax records aligned.

What determines the start of the tax period

The starting point for taxation is the company's first financial year beginning on or after 1 June 2023. Every company has its own reference date, depending on its legal form:

• Legal entities (LLCs, joint-stock companies, and others) — the tax period matches the financial year set out in the incorporation documents. Most often that's 12 months starting on 1 January or 1 June, though other dates do occur.
• Individual entrepreneurs (freelancers, Sole Establishments) — the rule here is stricter: regardless of internal reporting, the tax period always matches the calendar year, from 1 January to 31 December.

Can the tax period be changed

Yes — UAE law allows for this flexibility. A company can submit an application to the FTA to change the length of its tax period.

• Types of changes. The current tax period can be extended to a maximum of 18 months, and the following one can be shortened to a minimum of 6 months.
• Grounds for a changeaccepted by the FTA: liquidating the company; aligning financial years within a holding group; bringing the financial year in line with a head office or subsidiaries; obtaining certain tax relief; or other significant commercial or legal reasons.
• Application deadline — no later than 6 months after the end of the tax period you plan to change, provided the return for that period hasn't already been filed.

Key takeaways

The tax period matches the company's financial year — its start date is found in the incorporation documents. For sole proprietors and freelancers, the period is strictly the calendar year, January through December. Changing the period is possible with valid grounds and prior FTA approval.

Correctly determining and managing your tax period is the first step toward properly meeting your tax obligations in the UAE. If you're unsure how your situation applies, it's worth consulting a tax specialist to avoid mistakes in your reporting to the FTA.
