Key Takeaways
4 insights · 8 min readRecord keeping is a legal obligation under UAE Corporate Tax Law, with specific content, format, language and retention rules — not just good practice.
The base retention period is 5 years, but real estate records are 7 years, and a dispute or audit can add 4 more years.
Electronic records are valid if identical to the original and readable and reproducible throughout the period.
English is accepted, but the FTA can request a certified Arabic translation during an audit.
Under UAE Corporate Tax Law, every business must keep its accounting books and supporting documents for at least 5 years from the end of the tax period (7 years for real estate records), extended by up to 4 more years during a dispute or audit. Records may be kept as originals or as identical, readable electronic copies, in English — with a certified Arabic translation provided if the FTA asks.

Under UAE Corporate Tax Law, the FTA has the right to conduct tax audits and request any documentation needed to verify a company’s tax obligations — including whether the company should have registered for tax in the first place. If you cannot produce the records when asked, the FTA can make its own assessment of what you owe. Failing to maintain proper records is itself a penalty-attracting offence.
These obligations apply to all persons within scope of the Corporate Tax Law — taxable persons (registered businesses), non-taxable persons (those below the registration threshold), and anyone with potential CT or VAT obligations. If you hold a UAE trade licence and conduct any business activity, you are within scope, which is why record keeping sits at the centre of ongoing accounting and compliance.
What accounting books must you keep?
The law divides mandatory records into two categories — the accounting books themselves, and the supporting documents that prove the entries are correct. The core accounting books every UAE business must maintain are:
Category A — the accounting books
• Balance sheet & profit-and-loss accounts — the full picture of assets, liabilities, equity, income and expenses for each period; the foundation of any FTA review.
• Records of wages and salaries — employee names, salary amounts, WPS transfer records, bonuses and end-of-service gratuity provisions, for all staff whether sponsored or not.
• Records of fixed assets — the fixed asset register: cost, acquisition date, depreciation method and net book value at each period end.
• Inventory records — if you hold stock, quantities and values at the end of every relevant tax period, plus the stock counts that support them.
What supporting documents must you keep?
Every entry in your accounting books must be backed by a source document. The law requires all of the following supporting documents to be retained:
Category B — the supporting documents
• Invoices — sales and purchase — every sales invoice issued and every purchase invoice received; the primary evidence of revenue and expenses, with VAT invoices especially critical.
• Contracts — all signed business contracts: client agreements, supplier contracts, employment contracts, leases and service terms.
• Correspondence & licences — business correspondence relevant to transactions (including emails evidencing terms or completion), plus all trade, professional and regulatory licences.
• Tax election & calculation documents — documents evidencing any election under CT Law (Small Business Relief, QFZP status, realisation basis) and the calculations behind your CT computation, which the FTA can review years later.
The FTA can ask for more
Beyond these listed records, the FTA has a broad power to request any other information needed to verify a person’s tax obligations — including their responsibility to register. If you cannot produce something requested, the FTA may draw adverse inferences about your tax position. See how CT filing relies on these records →
How long must you keep records?
This is where many businesses get caught out — assuming five years is always enough. The base period is 5 years, but extensions can push the requirement well beyond that.
| Record type / situation | Retention | Runs from |
|---|---|---|
| Accounting records — taxable persons | 5 years | End of the tax period |
| Records — non-taxable persons | 5 years | End of the calendar year created |
| Real estate records | 7 years | End of the calendar year created |
| Dispute / tax audit / audit notified before base ends | + 4 years | That date (or until the dispute is settled, if later) |
| Voluntary disclosure in year 5 | + 1 year | The voluntary-disclosure submission date |
| Legal representative (e.g. a liquidator) | 1 year minimum | End of the legal representation |
[VERIFY: the retention periods and the governing instrument should be confirmed against primary sources before you rely on them. The base period is stated here as 5 years — reconcile this against Corporate Tax Law Article 56 and the Tax Procedures record-keeping rules, and note that VAT records (especially real-estate/capital-asset records) can carry different, longer periods.] A Legal Representative such as a liquidator cannot simply delete everything once a company is struck off — they must retain the books for at least a year after their representation ends.
What do the retention extensions mean in practice?
The extensions matter most when the FTA is already looking at you. These worked examples show how the clock changes.
| Scenario | Records required until |
|---|---|
| Standard — tax period ends Dec 2024, no dispute or audit | Dec 2029 (5 years) |
| Audit notified — FTA notifies audit intention in Dec 2028 | Dec 2032 (5 + 4 years) |
| Active dispute — dispute raised Dec 2028, settled Dec 2034 | Dec 2034 (until settled) |
The practical lesson: never destroy records the moment the base five years is up without first checking whether an audit notification or dispute has extended the clock. If in doubt, keep them.
In what format must records be kept?
UAE law does not require everything on paper. There are two equally valid methods — original documents, or identical electronic records.
| Method | What is required |
|---|---|
| Original documents | Retain the physical originals (invoices, signed contracts, bank statements). No extra conditions, and the strongest evidentiary value in an FTA audit. |
| Electronic records | Must be identical to the original, remain available and easily readable throughout the retention period, be reproducible on FTA request, and enable the FTA to verify tax obligations. |
Cloud accounting software (Zoho Books, QuickBooks Online, Xero), scanned invoices in a cloud drive, emailed invoices and digital bank-statement exports all qualify — provided the system stays accessible, the data is not altered from the original, and you can produce it promptly. Deleting an old accounting-software account mid-retention-period is a real risk: archive access, even read-only, must be maintained throughout.
Which language must records be in?
English is accepted. The FTA will accept records, data and documents submitted in English, so a business operating in English does not need to maintain a parallel Arabic set of books for routine compliance. However, the FTA can, at its discretion, request that some or all documents be translated into Arabic — and any translation must be certified under UAE translation law and submitted within the FTA’s timeframe.
The practical implication: day-to-day English accounting is fine, but if you receive an FTA audit notice, budget for potential certified-translation costs, especially where the audit covers voluminous records.

How do you stay compliant — and what are the common mistakes?
Staying compliant comes down to a short routine, and avoiding a handful of gaps we see repeatedly when taking on new clients.
- Maintain the accounting books — balance sheet and P&L, payroll, fixed assets and inventory, every period.
- Keep every supporting document — sales and purchase invoices, contracts, correspondence, licences and election documents.
- Retain for the right period — 5 years base, 7 for real estate, and check for audit, dispute or voluntary-disclosure extensions.
- Store it properly — originals or identical, readable electronic copies, with archive access kept throughout.
- Be ready to produce it — in English, with a certified Arabic translation if the FTA asks.
Compliant record keeping
- Both sales and purchase invoices retained
- All salary, freelance and director payments documented
- CT election documents and calculations kept
- Complete backup exported before cancelling any software
Common mistakes we see
- Deleting old accounting software to save money — losing years of records
- Keeping sales invoices but not purchase invoices
- Missing freelance, contractor and director-drawing records
- Assuming 5 years is always enough, without checking extensions
If records are already behind or incomplete, the fix is a structured backlog rebuild; and if you are moving firms, request everything on the accounting handover checklist before your access is revoked.
