UAE Corporate Tax Deadlines in 2026 Filing Dates by Financial Year End

A company with a 31 December 2025 year-end must file its Corporate Tax return and pay any amount due by 30 September 2026. That date affects many UAE businesses, yet it is not the deadline for every company. Your own date comes from the end of your financial year, followed by nine months. Filing and payment fall on the same day. This guide covers the full list of 2026 deadlines, registration rules, tax rates, reliefs, filing steps, and penalties.

‍

The Core Rule: Nine Months After Your Financial Year-End

‍

Start with the date shown in your financial statements. Count forward nine months. The result is your return and payment deadline.

‍

A company that closes its books on 31 December 2025 files by 30 September 2026. A company with a 31 March 2026 year-end files by 31 December 2026.

This is where many teams go wrong. They copy the 30 September date from another business, then discover that their own financial year ends in March or June.

Check three places before adding the date to your finance calendar:

• The financial statements
• The Corporate Tax registration record
• The tax period shown in EmaraTax

Your trade licence renewal date does not set the filing deadline.

A new company’s first financial year can run from six to 18 months, so check the period in EmaraTax.

‍

Can You Get an Extension?

‍

There is no routine extension for an ordinary 2026 Corporate Tax return.

The FTA can move a date for a defined group through a formal decision. This happened for certain short tax periods in 2024. It was a one-off measure for a named group, not a normal request process for any company running late.

Plan around the date already shown in EmaraTax. A late audit, missing approval, or unfinished bookkeeping does not move it.

‍

Registration Deadlines in 2026

‍

A return cannot be filed until the business has a Corporate Tax Registration Number.

For natural persons, such as freelancers and sole proprietors, the 2026 registration date was 31 March 2026 where UAE business turnover exceeded AED 1 million during 2025.

The test uses gross business turnover. Net profit is not the test.

Salary, personal investment income, and qualifying real estate investment income do not count toward that threshold.

Every UAE resident company needs to register. This includes mainland entities and free zone companies. A free zone company expecting a 0% result still needs a registration number and an annual return.

A non-resident company with a UAE Permanent Establishment follows a separate registration clock:

Late registration carries an AED 10,000 penalty.

There is a waiver route for the late registration penalty. To use it, the taxable person must register and submit the first return within seven months from the end of the first tax period. This seven-month period applies to the waiver. It does not replace the normal nine-month filing rule.

‍

The UAE Corporate Tax Rate in 2026

‍

For most UAE businesses, the calculation has two bands:

• 0% on taxable income up to AED 375,000
• 9% on taxable income above AED 375,000

Suppose a business reports taxable income of AED 500,000. AED 375,000 falls into the 0% band. The remaining AED 125,000 is taxed at 9%, which gives a Corporate Tax bill of AED 11,250.

A company below AED 375,000 still files its return.

A separate 15% minimum rate applies to in-scope multinational groups under the UAE Domestic Minimum Top-up Tax. This applies to groups with consolidated global revenue of at least €750 million in at least two of the previous four financial years. It is not the rate used by a typical UAE SME.

Dubai is not tax-free for every business. The result depends on taxable income, reliefs, free zone status, and the type of income earned.

‍

Who Has to File  and Who Is Exempt

‍

You need to file when you are a Taxable Person under the Corporate Tax rules.

This covers:

• UAE resident companies
• Mainland businesses
• Free zone entities
• Foreign companies with a UAE Permanent Establishment
• Natural persons whose UAE business turnover exceeds AED 1 million
• Tax Groups through the representative parent company

A nil tax bill does not remove the return. Companies below the AED 375,000 taxable income threshold still file. The same applies to a business using Small Business Relief or a Qualifying Free Zone Person reporting income at 0%.

Exempt categories can include:

• Federal and Emirate government entities
• Certain government-controlled entities
• Qualifying public benefit entities
• Qualifying investment funds
• Qualifying pension and social security funds
• Qualifying extractive and non-extractive natural resource businesses

The registration position varies between exempt categories. Some must register and submit an annual declaration. Others may have no registration duty when they carry on no taxable business activity.

Check the exact exemption category before closing the file. "Exempt" does not always mean "nothing to submit."

‍

Small Business Relief and Free Zone Status

‍

These routes use different tests, so decide which one fits before filing.

‍

Small Business Relief

‍

Small Business Relief is open to an eligible Resident Person with revenue of AED 3 million or less in the current tax period and every earlier tax period.

The relief treats the business as having no taxable income for that period. The return is shorter, but the business still needs to file it.

You must select the relief inside the Corporate Tax return. EmaraTax does not apply it by default.

Revenue means total business revenue, not net profit.

A company can make AED 3.2 million in sales and earn very little profit. It still fails the revenue test. A business that exceeded AED 3 million in an earlier tax period cannot use the relief in a later period.

The relief applies only to tax periods ending on or before 31 December 2026.

Once the return is submitted without the election, the relief cannot simply be added later for that period.

‍

Qualifying Free Zone Persons (QFZP)

‍

A QFZP can receive 0% Corporate Tax on qualifying income. The conditions are checked each tax period.

The company needs:

• Adequate substance in the free zone
• Audited financial statements
• Transfer pricing compliance
• Revenue split between qualifying and non-qualifying income
• Non-qualifying revenue kept within the de minimis limit

The de minimis limit is the lower of:

• teAED 5 million
• 5% of total adjusted revenue

One mainland invoice does not automatically remove QFZP status. A large non-qualifying invoice can push the company above the limit, which can affect the whole period.

Review revenue line by line before opening the return.

A QFZP cannot elect for Small Business Relief in the same tax period.

‍

How to File Through EmaraTax

‍

Use the same filing order each year.

‍

Step 1: Close the books

‍

Finish bank reconciliations, sales, supplier costs, payroll, loans, fixed assets, and year-end journals.

The return starts from the financial statements, so bookkeeping gaps flow into the tax calculation.

‍

Step 2: Check whether an audit is required

‍

Audited financial statements are required for:

• A Taxable Person with revenue above AED 50 million
• Every QFZP
• A Tax Group, using audited special-purpose financial statements

Start the audit early. Waiting until September leaves little time for corrections.

‍

Step 3: Confirm the tax route

‍

Before entering the return, decide whether the business is using:

• Small Business Relief
• QFZP treatment
• The standard Corporate Tax calculation

Check the conditions against the actual accounts.

‍

Step 4: Complete the return

‍

Enter the accounting income, tax adjustments, allowable deductions, tax losses, reliefs, exemptions, and related-party details.

The taxable income in EmaraTax should agree with the final tax computation.

‍

Step 5: Submit and pay

‍

Send the return and settle any tax due by the same legal date.

Keep the submitted return, acknowledgement receipt, payment confirmation, tax computation, financial statements, and supporting schedules.

Finish a few days before the deadline. That leaves room for a failed payment reference, a locked login, or a signatory issue.

‍

Penalties for Late Filing and Late Payment in 2026

‍

Late filing is charged by month, including part of a month.

‍

A return filed four days late can still trigger one month of penalty.

Late payment creates a separate charge. The current rate is 14% per year, calculated monthly on the unpaid tax from the day after the payment deadline.

The two charges can run at the same time. A company can file late and pay late, so both penalties may appear on the account.

Late registration is separate again. Other administrative penalties can arise from an incorrect return, missing records, or failure to provide information requested by the FTA.

Keep Corporate Tax records for seven years after the tax period ends.

‍

2026 Corporate Tax Preparation Timeline

‍

For a company filing by 30 September 2026, the work should be spread across the year.

‍

By March 2026

‍

By March, registration and the tax period should be checked, and related-party transactions or owner balances identified.

Natural persons with 2025 UAE business turnover above AED 1 million had to register by 31 March 2026. Anyone who missed that date should register now and check the seven-month waiver conditions.

‍

April to June 2026

‍

Use April to June for final accounts, tax adjustments, and any required audit.

Review:

• Small Business Relief eligibility
• QFZP conditions
• Tax losses
• Entertainment costs
• Interest expense
• Owner and director payments
• Related-party transactions
• Non-qualifying free zone revenue

For a QFZP, classify revenue before starting the return.

‍

July to September 2026

‍

Finish the tax computation, approve the return, arrange payment, and submit through EmaraTax.

Set an internal deadline before 25 September 2026. A few spare days can make a real difference when a payment or portal issue appears.

A company with another year-end can use the same three-month plan. Count back from its own legal deadline.

Frequently Asked Questions

‍

What is the UAE Corporate Tax filing deadline for 2026?

‍

Your deadline is nine months after the end of your financial year. For a company with a 31 December 2025 year-end, the return and payment are due by 30 September 2026.

‍

Do free zone companies need to file at 0%?

‍

Yes. A free zone company still registers and files. A 0% tax result does not remove the annual return.

‍

Is Small Business Relief automatic if revenue is under AED 3 million?

‍

No. The business must meet the conditions and select the relief in the return. EmaraTax will not add it on its own.

‍

Does the UAE have 0% Corporate Tax?

‍

Yes, in limited parts of the system. The first AED 375,000 of taxable income is taxed at 0%. A QFZP can receive 0% on qualifying income. Taxable income above the threshold is normally taxed at 9%.

‍

Is Corporate Tax payment due on the filing date?

‍

Yes. The return and payment share the same deadline.

‍

Do natural persons use a company financial year?

‍

No. A natural person's tax period is the Gregorian calendar year.

‍

What records should a business keep?

‍

Keep financial statements, ledgers, invoices, bank records, fixed asset schedules, payroll support, loan records, related-party records, tax calculations, and filing confirmations for seven years.

Finding the date takes minutes. Preparing the return takes much longer.

Alpha Pro Partners can confirm the tax period, close the accounts, review Small Business Relief or QFZP status, prepare the tax calculation, file through EmaraTax, and organise payment before the deadline.
