Corporate Tax Return Filing Errors: 20 Mistakes That Trigger FTA Audits and How to Fix Them
The Federal Tax Authority (FTA) conducted 93,000 inspection visits in 2024. This number shows a 135% increase year-on-year. That number gives us a clear idea of the tax landscape of the UAE. The government is no longer interested in passiveness. Tax compliance is actively pursued in 2026.
The government’s active pursuit is backed by a fully operational digital system of the FTA. The agency is cross-referencing corporate tax returns of businesses with their VAT filings, customs records, and audited financials at scale. For most businesses, this is the second cycle and the errors that did slip in the first cycle are much less likely to slip through this time. The system has matured and technology is upgraded. Errors that slipped through in the first cycle are far less likely to slip through again.
Businesses need to up their guard and self correct not just because the FTA is inspecting, it is crucial because non-compliance can lead to very heavy penalties. Under Cabinet Decision No. 129 of 2025 (effective 14 April 2026), if the FTA discovers an error, it means a 15% penalty on the underpaid tax amount. But if you correct that error yourself through a voluntary disclosure, it will only cost you 1%. That’s a huge difference and a great impetus for UAE businesses to correct their tax errors and save massive amounts of money. On AED 100,000 of underpaid CT discovered six months late, that gap is AED 9,000 vs AED 15,000 – before interest.
We have listed here the 20 most common corporate tax return filing errors that can trigger FTA audits. For ease, we have organized them into five categories for swift analysis. Each entry comes with a solution. If you are a finance director, CFOs, or a tax manager at a company, this article is a must read for you.
Why Do Corporate Tax Return Errors Trigger FTA Audits?
FTA inspections may seem random and whimsical since the number has increased so much but the reality is that these inspections are necessitated only when the system calls for it. FTA’s digital systems connect EmaraTax data to VAT return records, audited financial statements, and customs declarations in real time. That means financial data is under real time scrutiny in the UAE and when business’ declared figures do not reconcile across those sources, an inspection, a query becomes a natural consequence. It is actually quite automated.
Under Federal Decree-Law No. 17 of 2025 (effective 1 January 2026), the FTA’s audit powers were formally expanded. The standard audit window is five years from the filing date – extendable to 15 years in cases of tax evasion. That’s a long tail of exposure for errors left unaddressed.
| What the FTA Cross-Checks | Why It Matters |
| CT return revenue vs. VAT total supplies | Unexplained gap = immediate audit query |
| CT return profit vs. audited financial statements | Figures must reconcile with adjustments documented |
| Customs records vs. import VAT declared | Undeclared imports affect both CT and VAT positions |
| Transfer pricing disclosures vs. financials | Related party transaction volumes must match TP schedules |
| QFZP claims vs. substance evidence | Zero-rate claims reviewed against headcount and cost data |
How the FTA's Risk-Based Audit System Actually Works
The FTA assigns a risk score to each return. Businesses that file late, claim unusual deductions, have high related-party volumes, or show mismatches between VAT and CT figures attract higher scores. Higher scores mean earlier audit attention.
What makes this harder to manage is that the score compounds over time. A business flagged once builds a compliance profile that affects future audit selection. For most UAE companies, 2025-26 represents their first live experience of an FTA corporate tax audit and first impressions in compliance cut both ways. In this context, it is quite obvious why businesses may be losing sleep over their risk scores because even a one time miscalculation can attract FTA audits in future.
| Risk Level | Common Triggers |
| Low | Clean reconciliation, on-time filing, no related-party anomalies |
| Medium | Minor VAT-CT gaps, first-time SBR claim, modest TP volumes |
| High | QFZP claims without substance evidence, large TP adjustments, late registration + late filing, revenue mismatch > 10% |
The FTA must notify you before initiating an audit. You have the right to respond. But that window is narrow and once audit notification arrives, Voluntary Disclosure is no longer an option.
20 Mistakes that Trigger FTA Audit
Like we explained how and why FTA audits are triggered and the penalties that can result from these audits. We also briefly explained how one time FTA audit can build a profile of risk for business, tarnishing the image before FTA and triggering automatic future audits.
Now let’s take a look at the mistakes that can lead to a much dreaded FTA audit:
Mistakes 1-5: Registration and Deadline Errors
Administrative errors are the most preventable category. They’re also the most common in first and second filing cycles because businesses underestimate how strictly EmaraTax enforces dates. Every error below generates an automatic system flag.
Mistake 1 - Filing Late or Missing the 9-Month Deadline
Your CT return must be filed within nine months of your financial year-end. For a 31 December 2025 year-end, that deadline is 30 September 2026. There is no grace period. Even one day late triggers the penalty.
Penalty: AED 500/month for the first 12 months. AED 1,000/month thereafter. Two years of delay = up to AED 18,000 in filing penalties alone (Cabinet Decision No. 75 of 2023).
How to fix it: File immediately — even if your tax payment isn’t ready. Filing and paying are separate obligations. Count back nine months from your year-end today and lock it into your tax calendar.
Mistake 2 - Late CT Registration (AED 10,000 Penalty)
CT registration deadlines are tied to your trade license or incorporation date. Natural persons with annual revenue above AED 1 million had a 31 March 2026 deadline. Missing it costs a flat AED 10,000.
Why the FTA finds it: The FTA cross-references trade license databases and VAT registration records to identify entities that should be CT-registered but aren’t. It’s one of the most automated checks in the system.
How to fix it: Register on EmaraTax immediately. If you’re already late, the next mistake explains a time-sensitive waiver that may still apply to you.
Mistake 3 - Missing the July 31, 2026 Late Registration Waiver Window
This is the most time-critical item in this guide. The FTA issued a one-time waiver: the AED 10,000 late registration penalty is waived if you file your first CT return within seven months of the end of your first tax period.
For a 31 December 2025 year-end, that window closes 31 July 2026. That is weeks away. Miss it and the penalty stands – permanently.
Who qualifies: Businesses in their first tax period only. QFZPs also qualify but must still file to demonstrate QFZP compliance.
How to fix it: Confirm your first tax period end date now. Calculate seven months forward. If you’re in scope, filing before 31 July 2026 is the single most impactful action you can take this month.
Mistake 4 - Wrong Tax Period Dates in EmaraTax
EmaraTax auto-populates tax period dates based on trade license records. But restructured entities, newly acquired businesses, or companies with non-calendar year-ends often enter incorrect start or end dates – causing return mismatches that trigger FTA queries.
Penalty: Incorrect return: AED 500 (first violation), AED 2,000 (repeat) under Cabinet Decision No. 129 of 2025.
How to fix it: Before submission, verify your EmaraTax tax period dates match your audited financial statements exactly. If you’ve already filed with wrong dates, a Voluntary Disclosure is the correction route.
Mistake 5 - Filing Without Paying the Tax Due
Filing on time does not mean you’re compliant. Payment is a separate obligation and non-payment accrues interest from the day it was due, not from when the FTA notices.
Penalty: 14% per annum on the outstanding CT balance (flat, non-compounding) under Cabinet Decision No. 129 of 2025, replacing the old 2% + 4%/month compounding model. The new rate is simpler but it still adds up fast.
How to fix it: Budget your CT payment alongside your filing date, not after it. Use the EmaraTax payment gateway. If you’re facing a cash flow constraint, making a partial payment immediately reduces the 14% p.a. interest base significantly.
Mistakes 6-10: Taxable Income Calculation Errors
This is the highest-risk category. Errors here directly inflate or deflate taxable income and any difference between your filed figure and the FTA’s own calculation of what you owe triggers a formal reassessment.
Mistake 6 - Treating Accounting Profit as Taxable Profit
The most common and most expensive mistake in the UAE CT system. Accounting profit is not taxable income. Federal Decree-Law No. 47 of 2022 requires specific adjustments and if your CT return figures mirror your P&L profit exactly, that itself is a red flag for the FTA.
Required adjustments include: adding back disallowable expenses, deducting exempt income, applying reliefs (participation exemption, transfer relief), and adjusting depreciation for investment properties per Ministerial Decision No. 173 of 2025.
How to fix it: Prepare a formal taxable income reconciliation schedule – a documented bridge from accounting profit to taxable income. This is the first document FTA auditors request. If it doesn’t exist, assume the audit gets harder from that point.
Mistake 7 - Failing to Add Back Disallowable Expenses
Certain expenses are non-deductible under UAE CT law and must be added back to your taxable income. Many businesses miss them because the accounting system treats them as ordinary expenses.
| Expense Type | Deductible? | Treatment Required |
| Fines and government penalties | No | Add back in full |
| Donations (non-qualifying entities) | No | Add back in full |
| 50% of entertainment and hospitality | Partial | Add back 50% |
| Interest exceeding 30% EBITDA cap | Partial | Add back excess |
| Director personal expenses | No | Add back + reclassify |
| Bribes or illegal payments | No | Add back in full |
How to fix it: Build a disallowable expenses tracker inside your accounting system. Pre-code each category before year-end.
Mistake 8 - Claiming Small Business Relief Incorrectly
Article 21 of Federal Decree-Law No. 47 of 2022 allows businesses with revenue at or below AED 3 million to elect zero taxable income through Small Business Relief (SBR). It’s available until 31 December 2026. But two errors appear repeatedly.
Error one: Assuming SBR is automatic. It isn’t. You must actively elect it in your return.
Error two: Claiming SBR when ineligible. QFZPs cannot claim SBR. Members of multinational enterprise (MNE) groups cannot claim SBR. Filing an ineligible SBR claim = understated CT = 15% FTA-discovered error penalty on the shortfall.
How to fix it: Run an eligibility check before electing. Confirm your group structure. The AED 3 million threshold applies to the current period AND all preceding periods.
Mistake 9 - Misapplying the AED 375,000 Threshold
The 0% rate applies to taxable income up to AED 375,000. The 9% rate applies to the amount above that. The threshold applies to taxable income – not to accounting revenue, not to turnover. These are not the same number.
The second common error here affects Tax Groups: each entity in a group does not get its own AED 375,000 threshold. The threshold applies at group level.
How to fix it: Calculate your threshold application after all adjustments to taxable income are made. If your entity is part of a Tax Group, confirm where the threshold sits before filing.
Mistake 10 - Incorrect Foreign Tax Credit Calculations
UAE CT allows you to offset foreign taxes paid against your UAE tax liability but only for income genuinely taxed in the foreign jurisdiction. Errors include: claiming credits without supporting documentation, calculating credits on gross income instead of net, and double-counting across related entities.
Documentation required: Foreign tax receipts, assessment notices, and proof of payment all uploaded via the EmaraTax Tax Credit Schedule.
How to fix it: Maintain foreign tax payment evidence by jurisdiction, from the moment tax is paid abroad. Calculate credits per income stream. Do not net them against other adjustments.
Mistakes 11-14: Free Zone and QFZP Errors
The FTA’s scrutiny of free zone CT claims has intensified sharply in 2026. These four errors account for the majority of QFZP status challenges and losing QFZP status means retroactive 9% tax exposure on income you already reported at 0%.
Mistake 11 - Assuming Free Zone = Automatic 0% Tax Rate
Being based in a free zone does not give you a 0% CT rate. Only a Qualifying Free Zone Person (QFZP) earning Qualifying Income gets 0%. Every other free zone entity pays 9% on taxable income like any mainland business.
QFZP conditions are cumulative – you must meet all of them: adequate substance in the free zone, Qualifying Income as defined under Ministerial Decision No. 139 of 2023, a de minimis test (non-qualifying income must be ≤ 5% of total revenue or AED 5 million, whichever is lower), audited financial statements, and no election of mainland tax treatment.
How to fix it: Complete the Free Zone Schedule in EmaraTax in full. Don’t leave fields blank. Document your substance employees, costs, assets in the zone before you file.
Mistake 12 - Failing to Segregate Qualifying vs. Non-Qualifying Revenue
A QFZP must maintain a clean separation between income taxed at 0% and income taxed at 9%. Mixing the two in your ledger without clear classification produces exactly the kind of ambiguity the FTA flags.
Common mixing scenarios: selling to UAE mainland customers (non-qualifying income), income from excluded activities, and intercompany income from related parties not priced at arm’s length.
How to fix it: Label contracts and invoices as qualifying or non-qualifying at source from the first day of your financial year. Year-end classification of 12 months of mixed transactions is both inaccurate and time-consuming.
Mistake 13 - Insufficient Economic Substance in the Free Zone
A QFZP must have real substance in the free zone. Real employees. Real operating costs. Real assets that are proportionate to the qualifying income earned. A registered address with minimal activity does not meet the standard.
The FTA’s assessment compares substance metrics to income levels. A DMCC entity earning AED 50 million in qualifying income with one employee and AED 50,000 in annual costs is a substance failure – regardless of what the registration documents say.
How to fix it: Conduct a substance adequacy review before each filing cycle. Document headcount, cost allocation, and where key decisions are made. Our [VAT health check] service includes a QFZP compliance review.
Mistake 14 - Missing Audited Financial Statements
Two triggers mandate audited financials: annual revenue above AED 50 million, and QFZP status – regardless of size. There is no small-entity exemption for QFZPs.
The most common error here: small free zone businesses assuming the audit requirement doesn’t apply to them because their revenue is modest. If you’re a QFZP, size doesn’t matter. No audited financials = QFZP eligibility at risk.
Penalty: Failure to maintain required records: AED 10,000 (first offence), AED 20,000 (repeat).
How to fix it: Engage an FTA-accredited auditor well before your filing deadline, not after. ADEPTS is a DIFC-approved auditor with experience across free zone entities in DMCC, JAFZA, ADGM, and RAKEZ.
Mistakes 15-17: Transfer Pricing and Related Party Errors
Transfer pricing (TP) rules in the UAE apply to all related party transactions, not just large multinationals. A family-owned business with intercompany loans between two UAE entities must comply. A holding company charging management fees to an operating subsidiary must comply. The threshold for scrutiny is lower than most businesses assume.
For a full breakdown of UAE TP requirements, see our [transfer pricing UAE] guide.
Mistake 15 - Non-Arm's-Length Related Party Transactions
All transactions between related parties defined as entities with 50%+ ownership, board control, or connected person status must be priced as if conducted between independent parties. This is the arm’s length standard under Article 35 of Federal Decree-Law No. 47 of 2022.
Common violations: management fees charged below market rate, intercompany loans at 0% interest, shared services invoiced at cost with no margin, and royalties to related IP-holding entities without benchmarking support.
How to fix it: Conduct an annual TP review of all related party transactions. Price at market rates and document the commercial rationale. Retroactive repricing at year-end is a red flag in itself.
Mistake 16 - Incomplete Transfer Pricing Disclosure in the Return
The CT return requires disclosure of all related party transactions. Where transactions with a single related party exceed AED 40 million, or total related party transactions exceed AED 200 million, formal TP documentation (Local File and Master File) is mandatory under Ministerial Decision No. 97 of 2023.
The most common error: leaving TP disclosure sections blank, or partially completing them because the transactions “aren’t that material.” The FTA doesn’t make that judgment — you must disclose first and let the numbers speak.
How to fix it: Maintain a related party transaction register updated quarterly. Cross-check the register against TP disclosure requirements four to six weeks before filing.
Mistake 17 - Using General Estimates Instead of Benchmarking Studies
General estimates and management judgments are not accepted by the FTA as TP support. Benchmarking studies using recognized databases Bureau van Dijk’s Orbis, Bloomberg, TP Catalyst are the required standard. The search follows a three-step hierarchy: UAE comparables first, GCC/Middle East second, global comparables where local data is insufficient.
Absent a credible benchmarking study, the FTA applies its own arm’s length estimate which will not be in your favour.
How to fix it: Commission a formal benchmarking study from a TP specialist and refresh it annually. Last year’s study does not automatically satisfy this year’s filing. See our [transfer pricing benchmarking] service for the full scope.
Mistakes 18-20: Data Mismatch and Record-Keeping Errors
These three errors are the most common automated FTA audit triggers. EmaraTax catches them through cross-referencing before a human auditor ever reviews your file.
Mistake 18 - VAT-to-CT Revenue Reconciliation Gaps
The FTA automatically compares CT return revenue to VAT total supplies. Any unexplained difference triggers an audit query. There are legitimate reasons for a gap – VAT-exempt supplies, out-of-scope income, intercompany income, timing differences, free zone vs. mainland entity splits – but they must be documented.
The error isn’t the gap. The error is filing without a formal reconciliation that explains it.
How to fix it: Prepare a VAT-to-CT revenue reconciliation schedule before you file the CT return, not after. Every difference needs a documented explanation. Our [VAT vs. Corporate Tax Turnover Mismatch] guide walks through the methodology in detail, and our [VAT health check] service can run this reconciliation as part of your pre-filing review.
Mistake 19 - Personal/Director Expenses Coded as Business Expenses
Personal expenses of owners, directors, or shareholders that are coded as business expenses inflate your deductible cost base reducing taxable income incorrectly. The FTA doesn’t just catch this at a technical level. It reclassifies the amounts as undeclared benefits, which creates a second problem on top of the first.
Common examples: personal travel charged to the company, home renovation on the business books, personal credit cards reconciled as business expenses, school fees or family medical costs run through the P&L.
The FTA benchmarks expense ratios by industry. Unusually high G&A or travel lines relative to revenue draw attention. Bank statements are routinely requested during audits.
How to fix it: Establish and enforce a written expense policy. Separate business and personal bank accounts permanently. Reclassify before year-end. If directors have borrowed from the company, formalize those as loans with documented interest terms. Our [accounting and bookkeeping] team can implement the controls and clean up existing ledgers.
Mistake 20 - Incomplete Records: AED 10,000–20,000 Penalty
Federal Decree-Law No. 28 of 2022 requires all records supporting the CT return to be maintained for seven years. Records include: audited financial statements, trial balance, general ledger, bank statements, contracts, invoices, TP documentation, VAT returns, foreign tax receipts, and board minutes.
Cabinet Decision No. 17 of 2026 added a further rule: where a refund request remains pending and no final FTA decision has been issued, records must be retained for an additional two years beyond the standard period.
The FTA requests records within five business days of initiating an audit. Non-production carries a standalone AED 10,000 penalty (first offence) or AED 20,000 (repeat) – and allows the FTA to estimate your tax position based on whatever data they do have.
How to fix it: Set up a seven-year digital records archive, organized by tax period. Assign a records custodian. Don’t delete anything until the full retention period has expired.
What Should You Do If You Find an Error After Filing?
You have two options under UAE tax procedure law.
Option 1 – Amended Return: Available directly through EmaraTax for straightforward corrections that don’t involve underpaid CT.
Option 2 – Voluntary Disclosure (VD): The formal mechanism under Article 10 of Federal Decree-Law No. 28 of 2022. Required when the error results in underpaid CT, or when there’s a reportable omission even if no additional tax is due.
| Amended Return | Voluntary Disclosure | |
| When to use | Minor corrections, no tax difference | Underpaid CT, material omissions |
| Penalty | AED 500–2,000 (incorrect return) | 1% per month on unpaid tax |
| FTA-discovered equivalent | — | 15% of unpaid CT + 14% p.a. interest |
| Can file after audit starts? | No | No — VD window closes on audit notification |
| Recommended route | Simple data corrections | Any error with financial impact |
The golden rule: self-correct before the FTA initiates an audit. The moment you receive audit notification, Voluntary Disclosure is no longer available to you. Our [FTA-approved tax agents] team manages VD submissions and can calculate your exact exposure before you file.
The Voluntary Disclosure Calculation: Is It Always Worth It?
Mathematically, yes, almost always. But the timing determines everything. Take AED 100,000 in underpaid CT, identified six months after the filing deadline.
- Voluntary Disclosure cost: 1% per month × 6 months × AED 100,000 = AED 6,000
- FTA discovery at audit: 15% penalty = AED 15,000 + 14% p.a. interest on AED 100,000 = AED 14,000/year. Total 6-month exposure: AED 22,000+
The gap widens the longer you wait. And the gap disappears entirely the moment the FTA sends an audit notification because at that point, you lose the right to voluntary disclosure.
The one scenario where VD math gets more complex: where the underlying error also creates secondary adjustments across other periods, or where it intersects with a TP position that may require restating multiple years. In those cases, a structured review before filing VD is worth the cost.
As Alvarez & Marsal noted in their December 2025 analysis of FTA compliance trends, risk-based audit selection in 2026 is targeting entities with consistent filing anomalies, not just single-period errors. That means a VD filed now also reduces your forward risk profile, not just your current liability.
ADEPTS: Your Audit-Ready CT Filing Partner
Businesses we work with often come to us after receiving an FTA query, when the gap between what was filed and what should have been filed has already started generating interest. The conversation is always more straightforward and less expensive before that point.
ADEPTS is an FTA-approved tax agent and DIFC-approved auditor. Our corporate tax team covers the full filing lifecycle: pre-filing health checks, taxable income reconciliation, QFZP compliance reviews, transfer pricing documentation, Voluntary Disclosure submissions, and FTA audit representation.
Specific to the 20 errors in this guide, we offer:
- CT return review and pre-filing health check – catch errors before submission, not after
- VAT-to-CT reconciliation – the most common automated audit trigger, managed before filing
- QFZP eligibility and substance review – substance documentation, income segregation, financial statement coordination
- Transfer pricing documentation – Local File, Master File, benchmarking studies using Orbis and TP Catalyst
- Voluntary Disclosure management – calculation, drafting, and submission before audit notification
- FTA audit response – representation, document production, correspondence management
Every business situation is different. If any of the 20 errors above sound familiar, the time to address them is now not when the FTA acts first. Speak to our corporate tax advisory UAE.
Conclusion
UAE corporate tax enforcement in 2026 is operating at a different level of sophistication than it was 18 months ago. FTA’s digital cross-referencing catches mismatches that would have required manual audit work in the past. The 93,000 inspection visits in 2024 weren’t random and neither are the queries going out to CT filers this year.
The 20 errors in this guide fall into five categories. Most are preventable with discipline applied across the year not just in the weeks before filing. And for any error already made: Voluntary Disclosure is almost always cheaper than audit discovery, by a margin that compounds the longer it’s left.
The UAE tax system is maturing rapidly. OECD alignment, DMTT implementation for large MNEs, and R&D incentive frameworks expected later in 2026 will add further complexity. Businesses that build their compliance infrastructure now clean ledgers, formal reconciliations, proper TP documentation, timely filings, will carry that advantage into every future filing cycle.
FAQs:
Your CT return must be filed within nine months of your financial year-end. For businesses with a 31 December 2025 year-end, the deadline is 30 September 2026. For non-calendar year-ends, count nine months forward from your year-end date. EmaraTax records the submission timestamp, and there is no grace period, even one day late triggers the late filing penalty under Cabinet Decision No. 75 of 2023.
Not automatically. Only a Qualifying Free Zone Person (QFZP) earning Qualifying Income receives the 0% CT rate. Free zone status alone does not qualify you. You must meet all QFZP conditions simultaneously: adequate substance in the zone, qualifying income per Ministerial Decision No. 139 of 2023, the de minimis test on non-qualifying income, and audited financial statements. Failing any single condition moves your income to the standard 9% rate.
The AED 10,000 late registration penalty is reinstated permanently. The FTA’s one-time waiver applies only to businesses filing their first CT return within seven months of their first tax period end. Miss the 31 July 2026 deadline and the penalty stands with no further waiver mechanism available. File immediately if you’re in scope this window does not reopen.
Yes, this is one of the most automated checks in EmaraTax. The FTA compares CT return revenue against VAT total supplies across the same period. Any unexplained difference generates an audit query. Legitimate differences exist (VAT-exempt income, intercompany supplies, timing gaps) but must be documented in a formal VAT-to-CT reconciliation before filing.
The FTA uses a risk-scoring model based on return data. Key audit triggers include: revenue mismatches between CT and VAT filings, unusual deduction ratios against industry benchmarks, large related-party transaction volumes, QFZP claims without adequate substance evidence, late filings, and prior compliance history. Businesses that accumulate risk flags across multiple periods build a profile that increases audit likelihood in subsequent cycles.
AED 500 per month for the first 12 months, rising to AED 1,000 per month thereafter. A business filing two years late faces up to AED 18,000 in filing penalties alone, before any tax-related penalties are applied. This is under Cabinet Decision No. 75 of 2023 and is applied automatically by EmaraTax.
A Voluntary Disclosure (VD) is the formal mechanism under Article 10 of Federal Decree-Law No. 28 of 2022 for correcting material CT return errors. It is required when an error results in underpaid CT, or when there is a reportable omission, even if no additional tax is technically due. A VD must be filed before the FTA initiates an audit. Once audit notification is issued, the VD option is no longer available.
In almost every case, yes. The VD penalty is 1% per month on the unpaid tax amount. The FTA-discovery penalty is 15% of the unpaid amount, plus 14% per annum interest on the outstanding balance. On AED 100,000 of underpaid CT, a VD filed six months after the deadline costs AED 6,000. FTA discovery of the same error at the six-month point costs AED 22,000 or more. The gap widens materially with time.
Non-deductible expenses include: government fines and penalties, donations to entities not on the Cabinet Decision No. 37 of 2023 qualifying public benefit list, 50% of entertainment and hospitality costs, interest exceeding the 30% EBITDA cap, personal expenses of directors or shareholders, and any payments that constitute bribes or illegal transactions. These must be added back to accounting profit when calculating taxable income.
No. Small Business Relief (SBR) requires an active election in your CT return — it is not applied automatically. You must also be eligible: QFZPs cannot claim SBR, and members of MNE groups cannot claim SBR. The AED 3 million revenue threshold must be met in the current period and all preceding tax periods. An ineligible SBR claim results in understated CT and triggers a 15% FTA-discovery penalty on the shortfall.
All related party transactions must be disclosed in the CT return. Where transactions with a single related party exceed AED 40 million, or total related party transactions across all parties exceed AED 200 million, a formal Local File and Master File are required under Ministerial Decision No. 97 of 2023. Pricing must be supported by benchmarking studies using recognized databases. General management estimates are not accepted.
Seven years from the end of the tax period under Federal Decree-Law No. 28 of 2022. Cabinet Decision No. 17 of 2026 added a further obligation: where a refund request is pending and no final FTA decision has been issued, records must be retained for an additional two years beyond the standard period. Records include financial statements, ledgers, bank statements, contracts, invoices, TP documentation, and board minutes.
For minor corrections with no tax difference, file an amended return through EmaraTax. For errors that result in underpaid CT or material omissions, file a Voluntary Disclosure under Article 10 of Federal Decree-Law No. 28 of 2022. Do not wait to see if the FTA identifies the error — the Voluntary Disclosure penalty (1% per month) is always lower than the FTA-discovery penalty (15% of underpaid CT), and the VD option closes the moment audit notification is issued.
Yes. The arm’s length standard under Article 35 of Federal Decree-Law No. 47 of 2022 applies to all transactions between related parties — including two UAE entities under the same ownership. Intercompany loans must carry a market interest rate, management fees must reflect market pricing, and shared service charges must include an appropriate margin. Pricing at cost with no markup is not automatically compliant.
The standard audit window is five years from the filing date. Under Federal Decree-Law No. 17 of 2025 (effective 1 January 2026), the FTA can extend this to 15 years in cases of tax evasion or deliberate non-disclosure. The FTA must notify you before initiating any audit and you retain the right to respond — but the extended window means the exposure tail for serious errors is significantly longer than most businesses plan for.
