UAE FTA Tax Audit Red Flags: 15 Problems That Can Trigger Questions
The UAE Federal Tax Authority (FTA) can review a taxable person’s tax affairs and the records supporting information submitted to the FTA. The biggest audit risks are usually not one small accounting mistake. They are inconsistencies between the company’s tax returns, financial records, invoices, bank activity, accounting system and supporting documents. Common FTA tax audit red flags include:
- 1.Missing accounting records
- 2.Incorrect Corporate Tax return information
- VAT and accounting records that do not agree
- 4.Unexplained large adjustments
- 5.Related-party transactions without proper support
- 6.Unsupported expenses
- 7:Incorrect treatment of taxable income
- 8.Missing asset records
- 9.Poor documentation for exempt or special tax positions
- 10.Repeated corrections or amendments
- 11.Late filing or payment
- 12.Inconsistent information across FTA submissions
- Weak transfer pricing documentation where applicable
- 14.Poor records for transactions with connected persons
- 15.Inability to explain how a figure in the tax return was calculated
The FTA has specifically reminded Corporate Tax taxpayers that records must support information reported in Tax Returns and other filings. It also states that required records should generally be retained for at least seven years after the end of the relevant Tax Period.
Overview
What Is an FTA Tax Audit?
An FTA tax audit is a review of a person’s tax affairs by the UAE Federal Tax Authority. The purpose is to check whether the information reported to the FTA is accurate and whether the taxpayer has followed the applicable tax rules. For Corporate Tax, this can include checking the company’s:
- Financial statements
- Accounting records
- Sales
- Expenses
- Assets
- Liabilities
- Taxable income calculation
- Related-party transactions
- Tax adjustments
- Tax return
- Supporting documents
The FTA’s Corporate Tax guidance explains that the Authority may assess a person’s Corporate Tax affairs under the circumstances provided by the law. If the reported tax position is inaccurate or administrative requirements are not fulfilled, penalties may apply.
15 UAE FTA Tax Audit Red Flags
1. Missing or Incomplete Accounting Records
This is one of the most basic risks. A company should be able to show how the figures in its tax return were calculated. Important records an include:
- Sales records
- Purchase records
- Bank statements
- General ledger
- Invoices
- Credit notes
- Expense records
- Asset records
- Liability records
- Supporting contracts
2. Tax Return Figures Do Not Match the Accounts
Suppose the financial statements show one revenue figure but the Corporate Tax return contains a different amount without a clear explanation. That difference needs to be supported. The same applies to:
- Expenses
- Fixed assets
- Tax adjustments
- Taxable income
- Related-party transactions
A good audit file should make the movement from financial accounts → tax adjustments → taxable income → tax return easy to follow.
3. Unsupported Expenses
A business may record an expense in its accounts, but that does not automatically mean the tax treatment is correct. For every material expense, ask:
- What was purchased?
- Why was it purchased?
- Who supplied it?
- Is there an invoice?
- Is there a contract or other supporting evidence?
- How was it recorded in the accounts?
Weak documentation can make an otherwise genuine transaction difficult to defend.
4. Large or Unusual Tax Adjustments
A large tax adjustment deserves careful review. For example:
- A very large deduction
- A significant one-time adjustment
- A major change in taxable income
- A substantial adjustment between
- accounting profit and taxable income
The issue is not simply that an adjustment is large. The important question is: Can the company explain and support it?
5. Related-Party Transactions Without Proper Documentation
Transactions involving related parties or connected persons can require additional attention. Examples include:
- Management fees
- Loans
- Interest
- Shared services
- Asset transfers
- Group charges
- Intercompany purchases
- Intercompany sales
The company should maintain appropriate agreements, invoices, calculations and other supporting documents. Where transfer pricing rules apply, the required documentation should also be considered.
6. Missing Asset Records
The FTA has specifically identified records of assets, including purchases and disposals, among the records that taxable persons should maintain. This means companies should be able to trace important assets. For example:
- Purchase
- invoice
- accounting entry
- asset register
- depreciation/tax
- treatment
- disposal
If the asset register does not agree with the accounting records, investigate the difference before an FTA review.
7. VAT Records Do Not Match Accounting Records
If a business is VAT registered, its VAT records should be reconciled with its accounting system. Possible warning signs include:
- VAT return does not reconcile with sales
- Input VAT does not match purchase
- Missing tax invoices
- Incorrect VAT treatment
- Incorrect Tax Registration Number
- Unexplained VAT adjustments
A simple monthly reconciliation can identify many of these problems before they become larger issues.
8. Repeated Corrections and Amendments
Corrections are not automatically a problem. Businesses make genuine mistakes. However, repeated errors can indicate weak tax controls. Look for patterns such as:
- Repeated invoice corrections
- Repeated VAT adjustments
- Frequent changes to tax returns
- Recurring classification mistakes
- Repeated missing documents
The objective should be to identify why the error keeps happening, not simply correct it each time.
9. Inconsistent Information Submitted to the FTA
Information submitted through different tax processes should be consistent where the underlying facts are the same. Check items such as:
- Legal entity name
- TRN
- Business activities
- Revenue
- Financial year
- Related entities
- Ownership information
- Tax registration details
A mismatch does not automatically mean non-compliance, but unexplained differences should be investigated.
10. Poor Documentation for Special Tax Positions
If a company applies a special tax treatment, it should keep evidence showing why that treatment applies.
For example, where a business claims a particular treatment based on specific conditions, keep the documents proving those conditions.
Do not rely only on an accounting software setting or a note in the ledger.
The supporting evidence matters.
11. Late Filing or Payment
Late compliance can create penalties and should therefore be monitored. The FTA has reminded Corporate Tax taxpayers that Tax Returns and Corporate Tax payments are generally due within nine months from the end of the relevant Tax Period. For example, for a company whose Tax Period ends on December 31, 2025, the FTA gave September 30, 2026 as the filing and payment deadline in its example.
A tax compliance calendar should therefore be maintained.
12. Transactions That the Business Cannot Explain
This is a simple but important test. If someone asks: “Where did this number come from?” Your finance team should be able to answer. For important tax-return figures, maintain a clear audit trail. For example: AED 2,000,000 revenue should be traceable to:
Sales ledger → invoices → accounting system → financial statements → tax calculation → Tax Return
The easier this trail is to follow, the easier it is to defend the reported figure.
13. Poor Transfer Pricing Documentation
Companies with relevant related-party or connected-person transactions should review their transfer pricing obligations. Do not wait until an FTA review to discover that:
- Agreements are missing
- Pricing calculations are unavailable
- Supporting analysis is incomplete
- Related-party transactions were not properly identified
- Required documentation was not prepared
The exact requirements depend on the taxpayer and applicable rules, so the documentation should be assessed based on the company’s circumstances.
14. Accounting Records That Are Not Properly Maintained
This is especially important in 2026.
The FTA published FTA Decision No. 4 of 2026 concerning the rules and requirements for maintaining information contained in accounting records and commercial books. The decision was published on August 20, 2026.
Therefore, companies should review their record-keeping processes against the current requirements instead of relying only on an old internal checklist.
15. The Company Cannot Produce Supporting Documents Quickly
A simple internal test is useful: Pick 10 large transactions at random. Can your finance team quickly produce:
- Invoice
- Contract
- Payment evidence
- Accounting entry
- Related correspondence where relevant
- Tax treatment
- Supporting calculation
If it takes days to find basic documents, your audit-readiness is weak.
What Documents Should You Prepare Before an FTA Review?
Create a central tax audit folder containing, as applicable:
- Financial statements
- General ledger
- Trial balance
- Bank records
- Accounts receivable
- Accounts payable
- Corporate Tax returns
- VAT return
- Tax calculations
- Tax payment records
- Tax registration documents
- Relevant FTA correspondence
- Sales invoices
- Purchase invoices
- Credit notes
- Contracts
- Expense documentation
- Asset register
- Liability records
- Intercompany agreements
- Related-party transaction schedules
- Transfer pricing documentation where applicable
- Supporting calculations
The FTA specifically advises taxpayers to maintain records that support information submitted to the Authority.
How Long Should UAE Tax Records Be Kept?
For Corporate Tax purposes, the FTA states that relevant records should generally be retained for at least seven years following the end of the Tax Period to which they relate. Do not treat document storage as simply keeping PDFs in an email account. Use a structured system. For example:
2025 → Corporate Tax → Sales → Purchases → Bank → Assets → Related Parties → Tax Return
This makes future reviews much easier.
How to Check Your Company for FTA Audit Red Flags
Use this five-step review.
Check whether the financial statements agree with the accounting system.
Compare the relevant tax returns with the accounting records.
Select major sales, purchases, expenses and related-party transactions.
Make sure every material transaction has sufficient evidence.
For every major adjustment, document:
What is the adjustment?
Why is it required?
How was it calculated?
What evidence supports it?
How Much Does an FTA Audit Preparation Review Cost?
There is no single FTA audit-preparation fee that applies to every UAE company. The professional cost normally depends on factors such as:
- Number of transactions
- Number of entities
- Accounting quality
- VAT status
- Corporate Tax position
- Related-party transactions
- Number of Tax Periods
- Condition of supporting records
- Complexity of the business
How Long Does FTA Audit Preparation Take?
There is no universal preparation time. A basic internal review may be completed quickly if records are well maintained. A detailed review can take longer when:
Records are incomplete
Several years need checking
Multiple entities are involved
VAT and Corporate Tax need reconciliation
Related-party transactions require review
Accounting records need correction
The best time to prepare is before receiving an audit notice, not after.
What Should You Do If You Find a Tax Error?
Do not hide it or simply change the accounting entry without checking the tax consequences.
First:
Identify the error.
Determine the affected Tax Period.
Calculate the financial/tax impact.
Collect supporting documents.
Check whether a correction, disclosure, amendment or other procedure is required.
Keep evidence of the action taken.
If the tax treatment remains unclear after reviewing the applicable law and FTA guidance, the FTA provides a Private Clarification service for eligible cases.
