A Corporate Tax return is only as defensible as the paperwork sitting behind it. The figures a business reports, taxable income, deductions claimed, reliefs elected, mean very little to the FTA on their own; what actually supports them is the underlying accounting records, contracts, invoices, and calculations a business is required to keep, in the right form, for the right length of time. Record keeping is not a background administrative task running alongside Corporate Tax compliance. It is the evidence base the entire compliance position rests on.
Corporate Tax Record Keeping Requirements
Under Federal Decree-Law No. 47 of 2022, every taxable person is required to maintain the records and documents necessary to demonstrate that the information provided in its Corporate Tax return, and any related disclosures, is accurate and complete. This obligation applies regardless of a business’s revenue level or the amount of tax it actually owes; a business permanently within the 0 percent band still needs to maintain records supporting that position, in the same way a business paying substantial Corporate Tax needs to support its own figures.
The requirement is not limited to keeping a copy of the filed return itself. It extends to every category of underlying document that supports the figures within it, from the accounting system a business runs day to day through to the specific evidence behind a single deduction or relief claimed in a particular period.

Accounting Records
The foundation of Corporate Tax record keeping is the underlying accounting records a business maintains throughout each Tax Period: the general ledger, journal entries, bank statements and reconciliations, fixed asset registers, and any other books of account that support the financial statements prepared for that period.
These records need to be maintained on an ongoing basis, contemporaneously with the transactions they reflect, rather than reconstructed after the fact once a return is due or an FTA request arrives. Records assembled well after the transactions they describe are inherently less reliable, and considerably more time-consuming to produce accurately, than records kept as part of routine bookkeeping.

Financial Statements
A business needs to retain the financial statements prepared for each Tax Period, whether under full IFRS or IFRS for SMEs as applicable, along with the working papers and calculations that connect those financial statements to the accounting records behind them.
Where a business is required to maintain audited financial statements, whether due to exceeding a revenue threshold or, for every Qualifying Free Zone Person, regardless of revenue, the audit file itself, including the auditor’s report and supporting audit evidence, forms part of the records a business should retain alongside its own internal documentation.
Invoices
Sales and purchase invoices are among the most frequently requested records during any FTA review, since they provide direct, transaction-level evidence supporting both revenue recognized and expenses claimed.
Invoices need to be retained in a form that clearly shows the transaction date, the parties involved, the amount, and the nature of the goods or services provided, matched against the corresponding entries in the accounting records and, where relevant, the VAT treatment applied to the same transaction.
Contracts
Contracts and agreements supporting significant transactions, service agreements, lease agreements, financing arrangements, and, in particular, intercompany agreements between related parties, need to be retained as part of the supporting record base.
Contracts matter beyond simply confirming a transaction took place; they establish the terms a transaction was actually agreed on, which is frequently what an FTA review tests a reported figure against, particularly for interest, management fees, or other related-party arrangements subject to specific deduction limitations or transfer pricing scrutiny.

Tax Calculations
Beyond the accounting records themselves, a business needs to retain the specific calculation showing how taxable income was derived from accounting profit for each Tax Period: the tax adjustments applied, non-deductible expenses added back, exempt income deducted, reliefs and Tax Losses applied, and the resulting Corporate Tax liability calculated under the applicable rate structure.
This calculation working paper is distinct from the accounting records and financial statements themselves; it is the specific bridge between the two, and its absence leaves a filed return without a clear, reconstructable basis, even where the underlying accounting records are otherwise complete.
Supporting Documents for Deductions, Exemptions, and Reliefs
Every deduction, exemption, or relief claimed in a Corporate Tax return needs its own specific supporting evidence, not merely a general assumption that the underlying accounting records cover it.
This includes documentation supporting the business purpose of significant expenses, evidence that exempt income genuinely met the applicable conditions, such as ownership and holding period evidence for a participation exemption claim, and documentation supporting any election made, including Small Business Relief eligibility, Business Restructuring Relief conditions, or the realisation basis election, given how consequential and often irrevocable some of these elections are.
Transfer Pricing Records
Businesses with related party or connected person transactions face an additional, more specific layer of record keeping. This includes the disclosure information submitted with the Corporate Tax return, and, above the applicable thresholds, a Local File containing functional analysis and benchmarking evidence, and, for larger multinational groups, a Master File and Country-by-Country Report.
Supporting evidence for the transfer pricing method selected, the comparable data relied upon, and any benchmarking study performed needs to be retained alongside the disclosure itself, since a related party transaction recorded in the accounts without this supporting analysis behind it is difficult to defend if questioned. A full discussion of these specific requirements is covered in our dedicated transfer pricing documentation guide.
Record Retention Periods
Corporate Tax records must generally be retained for 7 years from the end of the relevant Tax Period. Where a tax refund request is pending for that period, this retention period is extended by a further 2 years, to 9 years total, under Cabinet Decision No. 17 of 2026, effective from April 2026. This extension applies specifically to periods with an open refund claim; a business should not assume the standard 7-year period is a safe universal cutoff without first confirming whether any refund request remains outstanding for the specific period in question.
This retention obligation applies to every category of record covered in this guide, not only the filed return itself. A business that discards underlying accounting records, contracts, or transfer pricing documentation after a shorter period, while retaining only the return, has not met the actual record keeping requirement, even though it holds onto the document the FTA would recognize most immediately.
Preparing Records for an FTA Audit
Well-organized, complete records are the single most effective form of audit preparation a business can maintain, precisely because they remove the need for last-minute reconstruction once an audit notification arrives. Records should be organized in a way that allows a specific figure in the Corporate Tax return to be traced back to its underlying source, the calculation working paper, the accounting entry, the invoice or contract, and, where relevant, the transfer pricing analysis, without requiring extensive searching or reconstruction under time pressure.
Businesses should periodically review whether their record keeping practices would actually hold up if requested tomorrow, rather than assuming records are adequate simply because a return was filed successfully. A full walkthrough of how an FTA audit unfolds, and specifically what gets examined, is covered in our dedicated Corporate Tax audit guide.

Digital Record Keeping and Format
UAE Corporate Tax Law does not require records to be kept in any single specific format, and digital record keeping is standard practice for most businesses, provided the records remain complete, accurate, and readily retrievable throughout the applicable retention period.
A business relying on cloud-based accounting software or digital document storage should ensure that access to historical records is genuinely maintained for the full retention window, including situations such as a system migration, a change of accounting provider, or a software subscription lapsing, any of which can otherwise result in records becoming inaccessible well before the retention period actually ends. Regularly verifying that archived digital records remain accessible, rather than assuming a past export or backup will still open correctly years later, is a simple but frequently overlooked safeguard.
