FAT Files | 87 Days to Your First UAE Corporate Tax Filing — Here’s What the FTA Is Actually Looking For

The Context: Your Filing Window Is Closing

If your company’s financial year ended on 31 December 2025, your UAE Corporate Tax return — and any tax payable — is due by 30 September 2026. That is 87 days from today.

For most UAE businesses, this is not just a filing. It is the first time the Federal Tax Authority (FTA) will see your taxable income calculation, your transfer pricing disclosures, your related-party transaction schedule, and your corporate tax adjustments — all in one place. And the FTA does not review these passively.

The FTA’s Strategy 2023–2026 confirms that tax audits are risk-driven, not random. The Authority cross-references data across VAT returns, Corporate Tax returns, ESR filings, financial statements, and — increasingly — e-invoicing data. Any inconsistency between any two data points can trigger a review.

This article explains how the FTA’s risk-based audit framework works, the seven red flags most likely to trigger scrutiny, why the Transfer Pricing Disclosure Form is the single highest-risk item for UAE businesses, and what to do in the 87 days you have left.

Part 1: How the FTA’s Audit Framework Actually Works

The FTA does not audit every taxpayer. It audits where the risk is highest. Understanding how it selects cases is the first step to not being selected.

Risk Indicators, Not Random Selection

Under the FTA’s risk-based compliance model, taxpayers are scored against a set of indicators. These include:

• Data mismatches — discrepancies between VAT returns, Corporate Tax returns, ESR filings, and financial statements
• Anomalous ratios — profit margins, effective tax rates, or related-party transaction volumes that deviate significantly from industry norms
• Behavioural flags — late filings, amended returns, history of VAT non-compliance
• Structural characteristics — complex group structures, cross-border volumes, free zone claims
• Documentation gaps — absence of contemporaneous evidence for material positions

A taxpayer with clean filings, consistent data, and contemporaneous documentation is a low-priority target. A taxpayer with unexplained loss claims, undocumented intercompany charges, and inconsistent VAT-CT data will be flagged — and the FTA’s digital infrastructure means the flag is raised automatically, not manually.

The Digital Audit Trail Is Already Built

Three developments make the FTA’s audit capability materially stronger in 2026 than it was even 18 months ago:

1. EmaraTax — the FTA’s integrated digital tax platform, which centralises all taxpayer data across VAT, Excise, and Corporate Tax
2. E-invoicing (Phase 1 live) — for businesses with AED 50 million+ revenue, every B2B invoice will be reported to the FTA in near real-time from January 2027, but the infrastructure is already being tested in the pilot phase
3. Cross-agency data sharing — the FTA exchanges data with licensing authorities, free zone regulators, and the UAE Central Bank

The result: the FTA can compare your Corporate Tax return against your VAT returns, your e-invoicing data, your ESR filing, and your licensing records — all before a human auditor opens the file.

Part 2: The Seven Red Flags That Trigger FTA Scrutiny

Based on the FTA’s published guidance, practitioner experience from VAT audits, and the Authority’s stated risk indicators, seven red flags stand out for Corporate Tax filers.

Red Flag 1: Large Year-on-Year Profit Fluctuations

An unexplained drop in taxable profit — particularly in a year when VAT-returned revenue is flat or growing — is an immediate mismatch. The FTA cross-checks revenue reported in VAT returns against revenue in the Corporate Tax return. If your VAT returns show AED 50 million in sales but your CT return shows a net loss, expect a question.

What to do: Prepare a reconciliation schedule that explains every material difference between accounting profit and taxable income. Every adjustment — depreciation differences, exempt income, non-deductible expenses — should be traceable to a specific provision of the Corporate Tax Law.

Red Flag 2: Consecutive Years of Losses

Losses are not inherently suspicious — but consecutive losses without commercial justification are. The FTA’s risk model flags entities that report losses for two or more consecutive periods, particularly where related-party revenue or management charges are material.

What to do: Document the commercial rationale for losses. If the entity is in a start-up phase, undergoing restructuring, or operating in a cyclical industry, that justification should be contemporaneous and specific. General statements about “market conditions” will not satisfy a reviewer.

Red Flag 3: Mismatches Between VAT and Corporate Tax Figures

This is the single most common audit trigger from the VAT era — and it applies with equal force to Corporate Tax. The FTA’s systems automatically compare:

• Revenue per VAT returns vs. revenue per CT return
• Expense claims vs. input VAT recovery patterns
• Intercompany charges vs. VAT treatment of the same transactions

A business that reports AED 10 million in VAT-taxable supplies but AED 7 million in CT revenue has a AED 3 million gap to explain. The FTA will notice.

What to do: Run a VAT-CT reconciliation before filing. Every line item that differs should be mapped and explained in your working papers.

Red Flag 4: Significant Related-Party Transactions Without Documentation

This is the highest-risk area for most UAE businesses — and the one where compliance is weakest. The FTA specifically reviews:

• Management fees charged to or by related parties
• Interest on intercompany loans
• Shared service cost allocations
• Director and shareholder payments
• Intellectual property royalties
• Goods transferred between group entities at non-market prices

Under the UAE Transfer Pricing rules, every related-party transaction must be priced at arm’s length. The Transfer Pricing Disclosure Form — mandatory for all taxpayers with related-party transactions — requires you to list each category of transaction, the counterparty, the value, and the transfer pricing method applied. If the form says “cost-plus, 5%” for a AED 20 million management fee but there is no supporting functional analysis or benchmark study, the FTA has grounds to adjust your taxable income.

What to do: Every material related-party transaction should have a transfer pricing file — even a simplified one. The documentation must be contemporaneous, meaning it exists at the time of the transaction, not when the FTA requests it.

Red Flag 5: Incorrect or Unexplained Corporate Tax Adjustments

The Corporate Tax return requires you to reconcile accounting profit to taxable income through a series of adjustments. Common errors include:

• Claiming entertainment expenses as fully deductible (only 50% is allowed)
• Treating non-deductible interest under the General Interest Deduction Limitation Rule as deductible
• Incorrectly classifying capital vs. revenue expenditure
• Omitting deferred tax adjustments required by the CT Law
• Claiming related-party expenses without arm’s-length justification

Each adjustment line is a potential audit entry point. If the adjustment is material and unexplained, it will be reviewed.

What to do: Every adjustment should reference the specific article of the Corporate Tax Law or Ministerial Decision that supports it. Keep a schedule that maps each adjustment to its legal basis.

Red Flag 6: Free Zone Entities Claiming 0% Without Meeting Conditions

Qualifying Free Zone Persons (QFZPs) can benefit from a 0% Corporate Tax rate on qualifying income — but the conditions are specific, and the FTA is reviewing QFZP claims actively.

The FTA checks:

• Whether the entity meets the substance requirements (adequate premises, employees, expenditure in the UAE)
• Whether qualifying income has been correctly identified and segregated from non-qualifying income
• Whether the de minimis test is met (non-qualifying income must not exceed 5% of total revenue or AED 5 million, whichever is lower)
• Whether audited financial statements are available
• Whether the entity has made a valid QFZP election

An entity claiming 0% on all income without a documented segregation between qualifying and non-qualifying revenue streams is at high risk of audit — and reversal of the 0% benefit.

What to do: Prepare a detailed qualifying/non-qualifying income analysis. Every revenue stream should be classified with reference to the QFZP conditions. If non-qualifying income exceeds the de minimis threshold, the entity ceases to be a QFZP for that period and is taxed at 9%.

Red Flag 7: Weak Record-Keeping and Missing Documentation

The Corporate Tax Law requires taxpayers to maintain records for seven years following the end of the tax period. This includes:

• Financial statements and underlying accounting records
• Transfer pricing documentation
• Intercompany agreements and contracts
• Board resolutions and management decisions affecting tax positions
• Correspondence with tax authorities
• E-invoicing data and ASP logs (for AED 50M+ businesses)

In a VAT audit, the FTA’s first request is usually for supporting documentation. In a Corporate Tax audit, the request will be broader — and if you cannot produce contemporaneous records, the FTA may disallow positions you have taken.

What to do: Build your audit file now — not when the FTA requests it. A well-organised audit file signals compliance maturity and can limit the scope of an audit.

Part 3: The Transfer Pricing Disclosure Form — Your Single Highest-Risk Filing

Of all the documents you will file with your Corporate Tax return, the Transfer Pricing Disclosure Form carries the highest audit risk for two reasons:

Reason 1: It Requires You to Self-Declare Your Risk

The Disclosure Form asks you to list every category of related-party transaction — by type, by counterparty, and by value — and to state the transfer pricing method you applied. This is essentially a self-assessment of your TP risk. A taxpayer that declares AED 100 million in related-party transactions applying the “cost-plus method” across all categories, without supporting documentation, is inviting review.

Reason 2: The Documentation Must Already Exist

The OECD Guidelines and the UAE TP rules require contemporaneous documentation. In practice, many UAE businesses have treated TP documentation as something to prepare “if the FTA asks.” This approach will not survive the Disclosure Form. The form asks you to confirm — under penalty of perjury — that your related-party transactions are at arm’s length. If you cannot produce the analysis that supports that confirmation, you have not complied.

Who Must File the Disclosure Form?

All taxpayers with related-party transactions during the tax period must file the Disclosure Form. There is no de minimis exception — even a single AED 1 transaction with a related party technically requires disclosure, though in practice materiality thresholds apply.

Thresholds for Master File and Local File:

• Standalone UAE entity revenue > AED 200 million, OR
• MNE Group consolidated revenue > AED 3.15 billion

Below these thresholds, Master File and Local File are not mandatory — but you must still demonstrate arm’s-length pricing if asked. A simplified TP file is strongly recommended even for smaller businesses.

Part 4: Practical 87-Day Action Plan

Here is what to do between now and 30 September 2026.

Week 1–2: Data Integrity Check (July 5–18)

• Reconcile revenue per VAT returns vs. revenue per financial statements vs. revenue per CT return
• Identify and document every material difference
• Verify that all related-party transactions have been identified and recorded
• Check free zone status: is the entity a QFZP? Has the election been made? Is the de minimis test met?

Week 3–6: Documentation Build (July 19–August 15)

• Prepare or update transfer pricing documentation for every material related-party transaction category
• Document the commercial rationale for any loss-making entities or periods
• Prepare adjustment schedules mapping every CT return adjustment to its legal basis
• Gather intercompany agreements, board resolutions, and management decisions supporting tax positions
• For QFZPs: prepare qualifying/non-qualifying income analysis

Week 7–10: Review and File (August 16–September 15)

• Have a tax professional review the return, Disclosure Form, and supporting documentation
• Run a pre-filing risk assessment: if you were an FTA auditor, what would you question?
• File the return through EmaraTax
• Retain a complete audit file — organised, indexed, and accessible

Week 11–12: Buffer (September 16–30)

• Two weeks of buffer for unexpected issues, additional data requests, or professional review delays
• Do not wait until 29 September to file

Part 5: What Happens If You Get It Wrong

The penalties for Corporate Tax non-compliance are material:

• Late filing penalty: AED 500 per month (first 12 months), AED 1,000 per month thereafter
• Late payment penalty: 4% per month on unpaid tax from the due date
• Transfer pricing adjustments: The FTA can adjust taxable income upward, resulting in additional tax at 9% plus penalties
• Inaccurate return penalty: 15% of the tax difference (minimum AED 500) for voluntary disclosure; higher for FTA-discovered errors
• Transfer pricing non-compliance: AED 10,000 to AED 100,000 per violation

Beyond the financial cost, an FTA audit is disruptive. Information requests, site visits, interviews with personnel — it consumes management time and creates uncertainty. The cost of compliance is almost always lower than the cost of non-compliance.

The Bottom Line

The FTA is not looking for perfect returns. It is looking for inconsistencies, unexplained positions, and undocumented transactions.

If your related-party transactions are priced at arm’s length, documented contemporaneously, and disclosed accurately on the TP Disclosure Form — your audit risk is low. If your VAT and CT figures reconcile, your adjustments are traceable, and your QFZP claims are substantiated — the FTA has little reason to open your file.

But if you are filing in September with a 5% cost-plus on everything, no documentation, unexplained losses, and mismatched VAT-CT data — you are playing audit roulette, and the FTA’s digital infrastructure means you will not win.

The 87-day clock is running. The documentation you build now is the defence you will rely on later.
