UAE Corporate Tax Deadline 2026: FTA Urges Businesses to File by September 30

The UAE Corporate Tax Deadline 2026 is approaching, and businesses with a financial year ending on December 31, 2025 have until September 30, 2026 to submit their Corporate Tax Returns and pay any Corporate Tax due.

The Federal Tax Authority (FTA) issued a reminder on September 2, 2026, urging Taxable Persons to complete their filing and payment obligations within the legally prescribed timeframe. The FTA also reminded businesses to prepare the required documents early to avoid last-minute compliance issues.

For UAE businesses, September 30 is therefore more than a date to mark on the calendar. It is an important tax compliance deadline.

What Is the UAE Corporate Tax Deadline?

The UAE Corporate Tax Deadline is the legal deadline by which a Taxable Person must submit its Corporate Tax Return and pay any Corporate Tax due for the relevant Tax Period.

Under the UAE Corporate Tax framework, Taxable Persons generally have no more than nine months from the end of their Tax Period to file their return and settle their Corporate Tax liability. A Tax Period is the period for which a business calculates its Corporate Tax obligations.

For businesses following a calendar financial year, this means:

Financial year ended	Corporate Tax deadline
December 31, 2025	September 30, 2026

Businesses with different financial year-ends may have different filing deadlines.

Who Must File by September 30, 2026?

The September 30, 2026 deadline applies to Taxable Persons whose financial year ended on December 31, 2025.

These businesses must:

• Submit their Corporate Tax Return.

• Pay any Corporate Tax due.

• Maintain the relevant records and supporting documents.

The requirement also applies to eligible businesses that elect for Small Business Relief.

Does Small Business Relief Mean You Do Not Have to File?

No. Small Business Relief is a Corporate Tax relief available to qualifying UAE Resident Persons that meet the applicable conditions. For eligible businesses, the relief can result in the business being treated as having no Taxable Income for the relevant Tax Period.

However, the FTA confirmed in August 2026 that businesses eligible for Small Business Relief must still meet their Corporate Tax compliance obligations, including registration, filing a simplified Tax Return and maintaining relevant records.

This means “no Corporate Tax payable” does not necessarily mean “no Tax Return required.”

What Records Should UAE Businesses Keep?

Corporate Tax compliance is not simply about submitting figures through an online portal. Businesses should have records that support the information reported in their Tax Returns.

The documents required can vary depending on the nature and size of the business. However, the FTA has highlighted records such as:

• Transaction records for the Tax Period

• Asset registers showing asset purchases and disposals

• Records of liabilities

• Records of shares and ownership interests

• Financial records supporting revenue and Taxable Income

• Documents supporting eligibility for Small Business Relief, where applicable

These records help support the accuracy of the information provided to the FTA and allow the authority to verify matters such as Revenue, Taxable Income and relief eligibility.

How Can Businesses File Their Corporate Tax Return?

Corporate Tax registration, return filing and payment are available through EmaraTax, the FTA's digital tax services platform. Businesses can file their returns directly through EmaraTax or seek assistance from approved Tax Agents listed by the FTA.

For business owners who are unfamiliar with Corporate Tax calculations or filing requirements, professional tax preparation support can help make the process more organised.

What Happens If You Miss the UAE Corporate Tax Deadline?

Missing a Corporate Tax filing or payment deadline can expose a business to administrative penalties.

The FTA has repeatedly urged businesses to complete their Corporate Tax obligations within the prescribed timeframe to avoid late filing and late payment consequences.

This is why businesses should avoid treating September 30 as the day to begin preparing. Reviewing financial records, checking eligibility for applicable reliefs and gathering supporting documents can take time.

A Simple Corporate Tax Preparation Checklist

If your business falls under the September 30, 2026 deadline, consider completing these steps as early as possible:

1. Confirm your Tax Period. Make sure your financial year ended on December 31, 2025 if you are relying on the September 30 deadline.

2. Review your financial records. Ensure your revenue, expenses, assets and liabilities are properly recorded.

3. Determine your Taxable Income. Review your accounting figures and apply the relevant Corporate Tax rules.

4. Check available reliefs. If you believe your business qualifies for Small Business Relief, make sure the election is properly addressed in your Corporate Tax Return.

5. Gather supporting documents. Keep transaction, asset, liability and ownership records relevant to your business.

6. File and pay on time. Complete your Corporate Tax Return and settle any amount due through EmaraTax before the applicable deadline.
