Most UAE tax audits do not start with an accusation. They start with a request for records. The Federal Tax Authority (FTA) can ask your business to produce invoices, contracts and accounts for past periods, and the companies that sail through are the ones that can produce them quickly and completely. This guide sets out what to keep, how long to keep it, and how to organise it before an audit notice ever arrives.
How Long You Must Keep Records
Under UAE tax rules, accounting records generally need to be kept for at least five years following the end of the relevant tax period, and longer in some situations β real estate records, for example, have historically carried a longer period under VAT rules, and records connected to an ongoing audit or dispute must be kept until the matter closes. Corporate tax follows a similar multi-year logic. Because periods vary by record type and rules are updated, confirm current requirements on tax.gov.ae and set your deletion policy to the longest period that applies to you.
In practice, nothing tax-related from the last five years should live only in a former employee’s inbox or a bookkeeper’s laptop. Everything should be in a system your business controls.
The Core Records Every Business Should Keep
Whether the FTA is reviewing VAT or corporate tax, the underlying evidence is largely the same. Make sure you can produce:
- Sales records: copies of every tax invoice and credit note you issued, with sequential numbering, customer details and TRNs where applicable.
- Purchase records: supplier tax invoices supporting every input VAT claim, plus proof of payment such as bank statements.
- Contracts and agreements: client contracts, leases for your office or shop, loan agreements and shareholder agreements that support the income and costs you declared.
- Financial statements and ledgers: your trial balance, general ledger, profit and loss and balance sheet for each period, plus audited financial statements where you are required to have them, such as free zone companies claiming the 0% rate.
- Import and export evidence: customs declarations, bills of lading, airway bills and proof of export for zero-rated supplies.
- Payroll records: employment contracts, Wage Protection System records and salary payments supporting staff costs.
- Corporate records: trade licences, Memorandum of Association, board resolutions and, for groups or related-party dealings, transfer pricing documentation.
Bank statements deserve special mention. They are the thread an auditor uses to test whether declared income is complete, so keep statements for every business account, including accounts you have since closed.
Digital Storage That Actually Works
The FTA accepts electronic records, which is good news for Dubai businesses drowning in paper. Scan supplier invoices as they arrive and store them in a cloud accounting system or structured folders organised by tax period. Name files consistently β date, supplier, invoice number β so a document can be found in seconds. Thermal receipts fade, so photograph fuel, parking and small cash receipts the day you receive them.
Keep at least two copies: your accounting software and a separate backup, such as a cloud drive or an external drive stored offsite. Check access rights too; if your bookkeeper leaves, you must still be able to open every file. Passwords for EmaraTax and your accounting system should be held by the owner or an authorised signatory, not only by an external accountant.
What Happens in an Audit, and How Records Help
An audit typically begins with an FTA notification and a list of requested records for specified periods. You are given a deadline, and the FTA may visit your premises. If your records reconcile β invoices match ledgers, ledgers match bank statements, returns match accounts β queries usually close quickly. Gaps or unexplained differences can lead to assessments, penalties and a wider review.
Do a self-audit once a year: pick one quarter, pull every document behind the VAT return you filed, and check corporate tax figures against your financial statements. Fix mistakes properly, using a voluntary disclosure where required, rather than quietly adjusting later numbers.
Record keeping is the cheapest tax insurance a small business can buy. Keep complete records for at least the required retention period, store them digitally with backups, and reconcile as you go. Check current retention rules on tax.gov.ae, and if an audit notice does arrive, involve a registered tax agent early β organised records make their job, and yours, far easier.
