UAE Tax Health Check: What to Review Before Filing

Quick answer: A Tax Health Check is a focused review of material tax positions, supporting records and filing information before a tax return is submitted. Its purpose is to identify unresolved questions and avoid relying only on the final numbers in the return.

A return can reconcile mathematically while the underlying treatment is incomplete. That is why a pre-filing review should look at contracts, invoices and accounting data as well as tax calculations.

1. Confirm the identity and filing details

Start with the entity’s legal name, Tax Registration Number where applicable, business activity, Tax Period, registration details and the person authorised to submit or approve the filing. Check that the correct entities and reporting periods are included.

These are straightforward controls, but a review that overlooks the basic facts can miss the legal perimeter of the tax position.

2. Review the Corporate Tax position—not only accounting profit

A Corporate Tax review should start from accounting income and examine the adjustments required by the Corporate Tax Law. Depending on the business, that can include exempt income, reliefs, nondeductible costs, interest restrictions, related-party transactions and elections.

For Free Zone companies, the review may also need to assess Qualifying Income, Excluded Activities, substance, audited accounts and de minimis compliance. Do not assume that all Free Zone income benefits from the same rate.

3. Reconcile financial records and tax calculations

Trace significant amounts from the Trial Balance and General Ledger to supporting schedules and, where available, the audited financial statements. Investigate unusual journal entries, year-end accruals, provisions, related-party balances and material changes from prior periods.

The objective is not to treat every accounting difference as an error. It is to identify which differences have tax consequences and to document the conclusion.

4. Review the VAT treatment of higher-risk transactions

A VAT return review should go beyond box totals. Examine the character of supplies and the supporting evidence, especially where the treatment depends on specific conditions.

Relevant questions may concern exported services, imports and the reverse charge, mixed taxable and exempt activities, credit notes, adjustments and input-tax recovery.

For a cross-border service, an overseas customer address is not by itself proof that the zero rate applies. The transaction needs to be checked against the VAT legislation.

5. Test the evidence behind the tax judgment

A reviewer should be able to connect each material position to the facts, relevant law and records. Where evidence is missing, the review report should identify what is required instead of silently assuming the best outcome.

An effective evidence file may contain contracts, invoices, customer and supplier records, transaction schedules, transfer-pricing analyses, approved working papers and written technical assessments.

6. Record findings in a management-ready report

Not every observation has equal importance. Group findings by severity, financial exposure, uncertainty and the action needed. Clearly state which areas were outside the review scope.

An effective report provides a practical route from issue to action: What was checked? What did the reviewer conclude? Why? What additional document or decision is needed? Who is responsible for it?

When should a business commission a Tax Health Check?

Useful triggers include the first Corporate Tax filing, a change in business model, a new overseas revenue stream, large related-party payments, uncertainty about Free Zone eligibility, a significant VAT refund or a planned acquisition.

A routine low-risk return may justify a lighter review than a complex restructuring. The scope should match the risk.

Frequently asked questions

Is a Tax Health Check the same as filing a tax return? No. Filing is the submission process; a health check focuses on the underlying tax positions, evidence and areas for correction or clarification.

Does the review guarantee that the FTA will agree? No. A review can improve the quality and documentation of the position but cannot guarantee a tax authority’s conclusion.

What documents should a company prepare? This depends on the scope. Common starting documents include financial statements, Trial Balance, General Ledger extracts, tax returns, contracts and relevant invoices.
