Bookkeeping and Audit in the UAE: Standard, Trigger, Deadline
For a finance team used to other jurisdictions, three questions cover most of it: what standard do we report under, what triggers an audit, and when is everything due. The UAE answers are simple in outline and expensive in detail, because corporate tax made the books the basis of the tax computation and, for free zone companies, the basis of the 0% claim.
Standard
Taxable income starts from accounting profit prepared under the applicable financial reporting standards and is then adjusted. That means the books are not a bank reconciliation with a P&L on top: they are the tax base. Whether a simplified standard is available for smaller companies depends on a revenue threshold that we confirm on the current date rather than quote from memory. Pick the standard in month one and build the chart of accounts for it; changing standard before the first return means rebuilding the year.
Audit: three separate triggers
- The free zone's own rules. Several zones require audited accounts to renew the licence, regardless of turnover or activity. Check the zone's rulebook, not the sales brochure
- Qualifying Free Zone Person status. Audited financial statements are a condition of the 0% rate under Ministerial Decision No. 84 of 2025. A company claiming the status without an audit is not a QFZP and pays 9% on all taxable income that is not Qualifying Income, from the first dirham
- Corporate tax itself. The audit obligation for tax purposes depends on revenue; the threshold is confirmed on the current date
A dormant company is not exempt by being dormant. If the zone requires an audit for renewal, it is done on nil accounts.
Deadlines follow the tax period
The tax period is the company's financial year. Registration with the FTA through EmaraTax comes first; missing the deadline costs AED 10,000. The return and payment are due within the statutory window after the period ends; a return not filed costs AED 500 per month for the first twelve months and AED 1,000 per month after that. VAT runs on its own registration and its own periods: mandatory once taxable supplies exceed AED 375,000 in 12 months, voluntary from AED 187,500. A company incorporated mid-year may have a first period that differs from the following ones; get the FTA's view on the first period before the first return is planned.
Records
Keep source documents for every transaction — contracts, invoices, delivery evidence, bank statements — and the registers the zone asks for. The statutory retention period is confirmed on the current date; plan on the FTA being able to ask for prior-period documents years later. For related-party dealings, transfer pricing applies: arm's length pricing, and documentation above thresholds we confirm on the current date. Intra-group balances without contracts and without a basis for the price are the first thing an auditor and the second thing the FTA will ask about.
Separate ledgers for QFZP status
If the company claims the free zone 0%, qualifying and non-qualifying revenue are kept in separate ledgers with separate cost allocation, by contract and counterparty, from day one. The de minimis cap — non-qualifying revenue not exceeding the lower of AED 5 million or 5% of total revenue — is checked quarterly. Books split retrospectively before the audit do not survive it, and the price of failing is loss of the status from the start of the current period and for the four following ones.
Group considerations
A UAE subsidiary of a multinational group with consolidated revenue of EUR 750 million or more falls under the 15% domestic minimum top-up tax from 1 January 2025; its local books feed the group's Pillar Two computation, so the group's timetable, not only the FTA's, drives the close. Small standalone companies with revenue of no more than AED 3 million may instead elect Small Business Relief for tax periods ending on or before 31 December 2029 — which removes the tax, not the books or the return.
What drives the cost
Transaction volume, number of counterparties, currencies and accounts, intra-group dealings, and whether an audit is required. A fee quoted without those inputs is not a fee. The expensive item is never routine bookkeeping; it is rebuilding a year from bank statements when the FTA or a bank asks for it.
A working rhythm
- Fix the financial year and write the calendar: period end, return, audit, VAT.
- Set up the chart of accounts for the chosen standard.
- Collect source documents monthly.
- Keep QFZP ledgers separate and test the cap quarterly.
- Engage the auditor at the start of the year.
- File, pay, and keep proof of both.
Frequently asked questions
Can the books be kept abroad?
The FTA cares that they are complete, compliant and available on request. In practice a local provider who knows EmaraTax and the zone's renewal requirements saves more than it costs.
Does a company under Small Business Relief still need books?
Yes. The relief removes the tax for the period, not the accounting, the registration or the return.
What if last year's books were never kept?
Rebuild them from statements and documents before the return. It is slower than current bookkeeping and cheaper than penalties and a lost status.
