How UAE Corporate Tax Affects Your Bookkeeping

UAE corporate tax has been in force since June 2023. For many businesses, it changed more than the tax bill. It changed the accountant’s month-to-month work.

This article explains what the CT Law asks you to record, how long to keep those records, and what changes if your company is in a free zone.

How corporate tax changed bookkeeping in the UAE

Corporate tax added another layer of accounting work on top of the records businesses already kept. Before CT, most UAE companies tracked books for VAT compliance and day-to-day management. Now they also need CT schedules, profit adjustments, and in some cases transfer pricing documentation. The core records still matter. CT just adds structure, extra schedules, and a seven-year retention rule.

UAE corporate tax applies under Federal Decree-Law No. 47 of 2022. It took effect for financial years starting on or after 1 June 2023. Most businesses filed their first CT return in 2024.

The main change is simple. Your financial statements now need to separate accounting profit from taxable income. Those two figures are often different.

What accounting records does UAE corporate tax require?

The CT Law requires records that support your tax return. In practice, that means:

Financial statements prepared under IFRS. The IFRS Foundation sets the accounting standards all UAE taxable persons must follow when preparing financial statements. Businesses with revenue under AED 50 million may use IFRS for SMEs as a simpler option. These statements form the base of your CT return.

Tax adjustments schedule. Your accountant prepares a reconciliation between accounting profit and taxable income. This covers disallowed expenses, exempt income, and other CT-specific adjustments.

Depreciation schedules. CT and accounting treat asset depreciation differently in some cases. Your accountant keeps a CT depreciation schedule to work out the correct tax deduction.

Related party transaction records. If your business deals with connected companies or individuals, those transactions must be documented. Large multinational groups must also file a Disclosure Form. Any business with related party dealings should keep an arm’s length justification on file.

Small Business Relief records. If your revenue is under AED 3 million and you claim Small Business Relief for tax years 2023 to 2025, you still need full records to support the claim. The relief lowers tax owed. It does not remove the record-keeping duty.

What is the CT record-keeping period in the UAE?

Seven years. The UAE CT Law requires records to be kept for seven years from the end of the relevant tax period.

That is longer than the VAT retention period of five years. If you are VAT-registered, keep everything for seven years. One retention policy covers both rules.

Do free zone companies have different CT bookkeeping rules?

Free zone companies can apply for Qualifying Free Zone Person (QFZP) status. A QFZP pays 0% CT on qualifying income. But this comes with strict conditions and specific accounting requirements.

To maintain QFZP status, a free zone company must:

• Maintain adequate economic substance in the free zone
• Earn qualifying income only. Non-qualifying income is taxed at 9%
• Keep separate accounts for qualifying and non-qualifying income
• Hold audited financial statements. These are mandatory for all QFZPs, no matter the revenue

That means free zone companies seeking QFZP status always need an audit. The substance rules also mean more detailed bookkeeping around headcount, premises costs, and day-to-day activity.

How your accountant handles CT month to month

A good accountant manages CT compliance alongside monthly bookkeeping. Here is how that works.

Monthly close. Your accountant records transactions in a way that supports the later CT reconciliation. That means coding expenses correctly from the start, not fixing them at year-end.

Year-end adjustments. At year-end, your accountant prepares the tax adjustments schedule. The process starts with accounting profit and ends with taxable income.

CT return filing. The return is filed through the Federal Tax Authority’s EmaraTax portal. The deadline is nine months after the end of the financial year.

FTA readiness. If the FTA selects your business for a CT audit, you need records ready fast. Monthly bookkeeping makes that easier. Catching up on a backlog under audit pressure is expensive.
