Accounting differences between mainland and free zone companies in the UAE

Both kinds of company keep full double-entry books, issue tax invoices once VAT registered, and file corporate tax returns. VAT registration follows the same thresholds wherever the company is licensed: mandatory above AED 375,000 of taxable supplies and voluntary from AED 187,500. Corporate tax records must be kept for seven years after the end of the tax period, and the return is due within nine months of the period end.

A mainland trading company in Deira and an IFZA consultancy in Dubai Silicon Oasis therefore start with much the same bookkeeping routine: capture bills, issue invoices, reconcile the bank, close each month and track VAT by line. The divergence begins at the income side of the ledger.

A mainland company pays 0% on taxable income up to AED 375,000 and 9% above it. If its revenue is AED 3 million or less and it meets the conditions, it may elect small business relief, which the Ministry has extended to tax periods ending on or before 31 December 2029.

A free zone company that meets the conditions to be a qualifying free zone person (QFZP) can pay 0% on qualifying income and 9% on income that is not qualifying. As DMCC’s own guidance puts it, the conditions include maintaining adequate substance, complying with transfer pricing rules and keeping audited financial statements. A QFZP cannot elect small business relief.

This is the practical difference in the ledger. A QFZP needs to know, for every revenue stream, whether it is qualifying. Mixed income is tested against a de minimis threshold, which DMCC summarises as the lower of 5% of revenue or AED 5 million. Cross that line with non-qualifying income and the 0% rate can be lost.

Worked example: a free zone company has AED 6 million of revenue. AED 5.6 million is from sales to other free zone and foreign customers that it treats as qualifying, and AED 400,000 is from services to mainland consumers. The de minimis limit is the lower of AED 300,000 (5% of AED 6 million) and AED 5 million, so AED 300,000. Non-qualifying revenue of AED 400,000 is above it. That is a conversation for a tax agent before year end, not after the return is due.

Mainland companies follow the commercial companies law and their own articles on audit; a QFZP needs audited financial statements for corporate tax purposes in any case. Free zones add their own rules on top. DMCC asks member companies to upload audited financial statements within six months of the financial year end using a DMCC approved auditor. IFZA now collects financial statements as part of licence renewal.

So a free zone company should plan its year-end around two calendars: the zone’s filing date and the corporate tax return date. The ledger needs to be closed and audit-ready well before the earlier one.

A few choices at the start make the difference between an easy year end and a forensic one.

• Separate revenue accounts for qualifying and non-qualifying income, not one “Sales” account.
• Customer records that note whether each customer is a free zone, mainland or foreign party.
• Related-party transactions tagged so transfer pricing records can be produced.
• A month-end report that shows non-qualifying revenue against the de minimis limit to date.

In HelloBooks you can set revenue accounts or classes for qualifying and non-qualifying income and the AI agent proposes the right one when it drafts an invoice, based on the customer and item. Ask “how much non-qualifying revenue have we booked this year?” and it answers from the ledger, with the invoices behind the number. Corporate tax computation support works from the same books.

The judgement about what qualifies stays with you and your tax agent. If you want the chart of accounts and AI categorization rules set up for a QFZP from day one, book a call at /book-a-demo.
