How to Identify FTA Audit Triggers Before You File Your UAE Corporate Tax Return in 2026

Meta description: Identify corporate tax UAE audit triggers before filing, reconcile records, reduce penalties and strengthen your FTA compliance position by September 30.

For UAE businesses with a financial year ending on 31 December 2025, the corporate tax return and any corporate tax payable are due by 30 September 2026. The Federal Tax Authority (FTA) has urged businesses to file and settle their liabilities within the required timeframe to avoid penalties.

The deadline is approaching quickly. However, filing on time is only one part of corporate tax compliance. Businesses should also review whether their return contains inconsistencies or unusual positions that could attract attention under the FTA’s risk-based audit approach.

The FTA can compare information across corporate tax returns, VAT filings, financial statements, customs records, bank information and other available data. A return does not necessarily need to contain an obvious error to create risk. Significant unexplained differences, unsupported deductions or weak documentation may lead to additional questions.

At my eloah business hub, we recommend completing a structured pre-filing review before submitting your return. This guide explains the main FTA audit triggers and provides a practical checklist for UAE business owners.

How to Understand the September 30 Corporate Tax Deadline

UAE corporate tax returns are generally due within nine months from the end of the relevant tax period. Accordingly, a business with a 31 December 2025 year-end should file its return and pay any corporate tax due by 30 September 2026.

Late compliance can create more than one financial exposure:

• AED 500 per month, or part of a month, for late filing during the first 12 months
• AED 1,000 per month from the 13th month onwards
• A separate 14% per annum late-payment penalty on unpaid corporate tax, calculated from the day after the payment due date

These penalties can apply even where a business eventually corrects its records. Therefore, the most cost-effective approach is to identify and resolve issues before submission.

Businesses should review the FTA’s official corporate tax filing guidance and obtain professional advice where their tax position is complex.

How to Identify VAT-to-Corporate-Tax Revenue Mismatches

One of the clearest risk indicators is a significant difference between revenue reported in VAT returns and revenue reported in the corporate tax return.

The figures may not always be identical. Legitimate differences can arise because of:

• Exempt or zero-rated supplies
• Non-VATable income
• Export transactions
• Accounting adjustments
• Prior-period corrections
• Fair-value movements or other non-operating income

The risk arises when the difference is not documented or cannot be explained clearly.

For example, if VAT returns show AED 12 million in taxable and zero-rated supplies while the corporate tax accounts report only AED 9 million in revenue, we should prepare a reconciliation showing exactly why the figures differ. The same review should compare the VAT returns with the general ledger, audited or unaudited financial statements and bank receipts.

Our VAT and corporate tax UAE support includes return preparation, taxable income calculations, QFZP assessments, transfer pricing guidance and reconciliation of accounting records. A documented bridge between VAT turnover and corporate tax revenue can help answer questions before they become an FTA concern.

How to Review Sustained Losses and Sharp Profit Swings

Losses are not automatically a corporate tax violation. A new business may incur start-up costs, while an established company may experience restructuring expenses, market disruption or a temporary decline in demand.

However, sustained losses without a clear commercial rationale can attract scrutiny, particularly where the company continues to maintain staff, premises, licences and substantial operations.

We should investigate:

• Consecutive years of reported losses
• Gross margins significantly below industry expectations
• Large changes in profit from one year to the next
• A sudden move from substantial profit to a loss
• Losses that conflict with bank inflows or reported commercial activity
• Profit volatility that is not supported by contracts, operational records or management explanations

Prepare a written explanation for any major movement. Supporting evidence may include board minutes, restructuring plans, customer cancellations, market analysis, impairment calculations, business forecasts and management accounts.

Where related-party pricing contributes to a low margin or loss, the business should also review its transfer pricing documentation and intercompany agreements.

How to Test Large or Unusual Deductions

The FTA may pay closer attention to large, unusual or one-off deductions, particularly where they significantly reduce taxable income.

Before filing, classify and test material expenses such as:

• Management fees
• Interest paid to shareholders or related entities
• Consultancy charges
• Provisions and write-offs
• Bad debt expenses
• Asset impairments
• Large marketing or commission payments
• Repairs that may actually be capital expenditure
• Personal or shareholder expenses recorded through the company

For each material deduction, we should be able to answer three questions:

1. What was purchased or paid for?
2. How did the expense support the business?
3. What evidence proves that the transaction occurred?

Maintain invoices, contracts, payment records, approval documents and correspondence. A bank transfer alone may not demonstrate that an expense was commercially necessary or tax-deductible.

The effective tax rate should also be reviewed. If deductions reduce taxable income substantially below what would normally be expected for the business activity, prepare a clear tax adjustment memo before submitting the return.

How to Document Related-Party Transactions and Transfer Pricing

Related-party transactions are a significant risk area in corporate tax UAE compliance. This includes payments between companies under common ownership, shareholder transactions, director arrangements and dealings with overseas group entities.

Potential warning signs include:

• Management fees without a written agreement
• Interest charges without clear loan terms
• Payments that reduce the UAE company’s profit significantly
• Services that are not supported by deliverables
• Transactions disclosed inconsistently in accounting records and tax filings
• Pricing that does not reflect the arm’s-length principle

We should maintain written agreements, invoices, payment evidence, descriptions of services and appropriate benchmarking where required. The UAE entity should be able to demonstrate what benefit it received and why the price is commercially reasonable.

Transfer pricing information should also be consistent with VAT treatment, customs values and the financial statements. If the transaction is material, specialist review should be completed before filing rather than after receiving an FTA query.

How to Reconcile Customs Data, Imports and Cost of Goods Sold

Trading, manufacturing, logistics and e-commerce businesses should compare their customs records with accounting data.

The FTA may identify inconsistencies between:

• Customs import declarations
• Supplier invoices
• Import VAT records
• Inventory movements
• Cost of goods sold
• Reported sales
• Gross profit margins

For example, a business reporting significant imports but unusually low inventory and cost of goods sold may need to explain whether goods were re-exported, held in stock, transferred to another entity or recorded in a different accounting period.

Before filing, reconcile bills of entry, shipping documents, freight and insurance costs, supplier statements, warehouse records and inventory reports. Keep explanations for valuation differences, timing differences and goods that were imported on behalf of another party.

How to Support a QFZP 0% Corporate Tax Claim

Free-zone companies should not assume that a free-zone licence automatically means all income is taxed at 0%. A Qualifying Free Zone Person (QFZP) must satisfy the applicable conditions and correctly distinguish qualifying income from non-qualifying income.

Risk can increase where:

• The business claims 0% on nearly all revenue without an income analysis
• Most customers or operations are on the mainland
• The company has limited staff, premises or operating expenditure
• Core income-generating activities do not appear to take place in the free zone
• The business cannot demonstrate management and decision-making activity
• Qualifying and non-qualifying revenue are not tracked separately

We should prepare evidence of premises, employees, business functions, operating expenses, contracts, customer locations and management decisions. Revenue should be reviewed invoice by invoice where necessary.

A QFZP assessment should be treated as a technical review, not a default assumption. Incorrectly claiming 0% may expose the business to additional tax, penalties and extended correspondence with the FTA.

How to Review VAT Refunds, Late Filings and Amendments

Frequent VAT refund claims can attract additional questions, particularly where input VAT consistently exceeds output VAT or refund claims are unusually large compared with the company’s activity.

The business should confirm that:

• Input tax relates to genuine business purchases
• Tax invoices meet the required standards
• Imports and reverse-charge transactions are correctly recorded
• Refund claims reconcile to the accounting system
• Any unusual refund period has a commercial explanation

Late, amended or repeatedly corrected filings can also signal weak internal controls. An amendment may be appropriate, but repeated changes should be investigated and documented. We should identify whether the underlying cause is poor bookkeeping, incorrect VAT treatment, missing invoices or a misunderstanding of corporate tax adjustments.

Cash-intensive and higher-risk sectors may also receive closer scrutiny because income can be more difficult to verify. Businesses in retail, hospitality, construction, real estate, precious metals, general trading and certain e-commerce activities should maintain particularly strong sales, cash, inventory and customer records.
