How UAE Corporate Tax Affects Your Bookkeeping

UAE corporate tax applies to financial years starting on or after 1 June 2023. For most businesses, it changed more than the tax bill. It changed what their accountant does every month.

This article explains what the CT Law asks you to record. It covers how long to keep records and what changes in a free zone. DASA Consulting’s UAE accounting services keep those records CT-ready for mainland and free zone companies.

How Has Corporate Tax Changed Bookkeeping in UAE?

Corporate tax added new accounting work on top of old duties. Before CT, most UAE businesses kept books for VAT and management. Now they also need CT schedules and adjusted profit figures. Some need transfer pricing records too. CT also adds a 7-year record rule.

UAE corporate tax comes from Federal Decree-Law No. 47 of 2022. For a calendar-year company, the first tax period was 2024. That first return was due by 30 September 2025.

The key change: you now separate accounting profit from taxable income. The two figures are rarely the same.

What Accounting Records Does UAE Corporate Tax Need?

UAE corporate tax needs records to back up your tax return. The main ones are IFRS financial statements and a tax adjustments schedule. You also need depreciation schedules and related party records. Small Business Relief claimants need the same full records. The FTA can ask for any of them.

Financial statements prepared under IFRS. The IFRS Foundation sets the accounting standards UAE taxable persons follow. Businesses with revenue under AED 50 million may use IFRS for SMEs instead. These statements are the base of your CT return.

Tax adjustments schedule. Your accountant links accounting profit to taxable income. This covers disallowed expenses, exempt income and other CT adjustments.

Depreciation schedules. CT and accounting sometimes treat depreciation differently. Your accountant keeps a CT depreciation schedule for the right tax deduction.

Related party transaction records. Do you deal with related companies or connected people? Document those transactions. You file a related party disclosure with your return when these deals pass AED 40 million in total. You also file a connected persons schedule when dealings with one connected person pass AED 500,000. Keep an arm’s length justification on file for all related party dealings.

Small Business Relief records. Is your revenue AED 3 million or less? You can claim Small Business Relief for tax periods ending on or before 31 December 2029. Ministerial Decision No. 131 of 2026 extended it to that date. You still need full records to support the claim. The relief cuts the tax. It doesn’t remove the record duty.

General bookkeeping rules still apply. See our article on UAE bookkeeping requirements for the full list. CT adds to those duties. It doesn’t replace them.

What Is the CT Record-Keeping Period in UAE?

Seven years. The CT Law sets 7 years from the end of the tax period. This is longer than the usual 5-year VAT period. Are you VAT-registered? Keep everything for 7 years. One policy then covers both taxes. Real estate VAT records are the exception.

Real estate VAT records need 15 years. Keep those longer than the rest.

Do Free Zone Companies Have Different CT Bookkeeping Rules?

Yes. A free zone company can be a Qualifying Free Zone Person (QFZP). A QFZP pays 0% CT on qualifying income. In return, it keeps separate records and audited financial statements. It also tracks non-qualifying income closely. Too much of it ends QFZP status for five tax periods.

To keep QFZP status, a free zone company must:

• Keep adequate substance in the free zone
• Keep non-qualifying revenue under the de minimis limit: 5% of total revenue or AED 5 million, whichever is lower
• Earn qualifying income from qualifying activities
• Meet the transfer pricing rules
• Hold audited financial statements, whatever its revenue

Go over the de minimis limit and you lose QFZP status. The loss covers that tax period and the next four. All taxable income then follows the standard rates: 0% up to AED 375,000 and 9% above.

So a free zone company seeking QFZP status always needs an audit. Substance rules also mean more detailed books on headcount, premises costs and operations.

How Your Accountant Handles CT Month to Month

A good accountant runs CT compliance alongside monthly bookkeeping. Here’s how that works.

Monthly close. Your accountant codes every transaction to support the year-end CT figures. Expenses get the right code from month one. Nothing waits for year-end fixes.

Year-end adjustments. At year-end, your accountant prepares the tax adjustments schedule. It starts from accounting profit and works down to taxable income.

CT return filing. You file the return through the Federal Tax Authority’s EmaraTax portal. The deadline is 9 months after the end of the tax period.

FTA readiness. The FTA may pick your business for a CT audit. Then you need your records fast. Monthly bookkeeping makes this simple. A backlog under FTA audit pressure is expensive to fix.

Frequently Asked Questions

Is bookkeeping required for UAE corporate tax?

Yes. The CT Law makes every registered taxable person keep records to back up the tax return. Keep them for at least 7 years.

Do small businesses in UAE need to change their bookkeeping for CT?

Yes. Businesses claiming Small Business Relief still need records to support the claim. The relief runs for tax periods ending on or before 31 December 2029. It cuts the tax owed. It doesn’t remove the record duty.

What happens if your UAE company fails to keep CT records?

The FTA can fine you for missing records. The FTA can also estimate your taxable income. That estimate may be higher than your real income.

Do free zone companies need audited accounts for CT in UAE?

Yes, if they want QFZP status. Every Qualifying Free Zone Person needs audited financial statements, whatever its revenue. Ministerial Decision No. 84 of 2025 sets this rule.
