How UAE Corporate Tax Affects Your Bookkeeping

UAE corporate tax has been in effect since June 2023. For most businesses, it changed more than the tax bill. It also changed what the accountant does every month.

This article explains what the CT Law requires you to record, how long to keep those records, and what changes if your company is in a free zone. DASA Consulting’s UAE accounting services can help keep those records CT-ready for mainland and free zone companies.

How corporate tax changed bookkeeping in the UAE

Corporate tax added new accounting work on top of what businesses already had to do. Before CT, most UAE businesses kept books for VAT compliance and day-to-day management. Now they also need CT schedules, adjusted profit calculations, and, in some cases, transfer pricing documentation. The basic records have not changed. CT just adds more structure and a 7-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 key change is simple: your financial statements now need to separate accounting profit from taxable income. Those two figures are rarely the same.

What accounting records does UAE corporate tax require?

The CT Law requires records that support your tax return. The law usually means this.

You need 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 alternative. These statements are the base of your CT return.

Your accountant prepares a tax adjustments schedule. It reconciles accounting profit with taxable income. It covers disallowed expenses, exempt income, and other CT adjustments.

Your accountant also keeps depreciation schedules. CT and accounting do not always treat asset depreciation the same way, so the schedule helps calculate the right tax deduction.

If your business deals with connected companies or individuals, you need related party transaction records. Large multinational groups must also file a Disclosure Form. All businesses with related party dealings should keep an arm’s length justification on file.

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 the tax due. 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 7 years from the end of the relevant tax period.

This is longer than the VAT retention period of 5 years. If you’re VAT-registered, keep everything for 7 years. That covers both rules with one process.

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 the status comes with strict conditions and more accounting work.

To keep QFZP status, a free zone company must maintain adequate economic substance in the free zone and earn only qualifying income. Non-qualifying income is taxed at 9%.

It must also keep separate accounts for qualifying and non-qualifying income and hold audited financial statements. Audited accounts are mandatory for all QFZPs, no matter the revenue level.

This means free zone companies that want QFZP status always need an audit. The substance rules also mean more detailed bookkeeping around headcount, premises costs, and daily operations.

How your accountant handles CT month to month

A good accountant handles CT compliance alongside monthly bookkeeping.

Monthly close matters. Your accountant records transactions so the books can feed into the CT reconciliation later. That means coding expenses correctly from the start, not fixing things at year-end.

Year-end adjustments come next. At year-end, your accountant prepares the tax adjustments schedule, starting from accounting profit and working down to taxable income.

CT return filing happens through the Federal Tax Authority’s EmaraTax portal. The deadline is 9 months after the end of the financial year.

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

If you need CT record-keeping and return filing handled, DASA Consulting does this for mainland and free zone companies.
