If 2026 is the year you file your UAE corporate tax return — whether it's your first or second time — this guide covers everything you need. We walk through every deadline, every deduction category, the EmaraTax filing process step by step, and the traps costing UAE SMEs money right now.
Corporate tax in the UAE is governed by Federal Decree-Law No. 47 of 2022, now in its third enforcement year. The rules are being interpreted in real time, penalties are real, and the Federal Tax Authority (FTA)'s enforcement capacity is growing fast. Getting this right matters.
Quick Answer: UAE corporate tax returns must be filed within 9 months from the end of your financial year through the EmaraTax portal. For calendar-year businesses ending 31 December 2025, the deadline is 30 September 2026. The 9% rate applies to taxable income above AED 375,000. Filing is mandatory even for free zone businesses and those with zero tax due.
2026 UAE Corporate Tax Filing Deadlines at a Glance
Your deadline depends on when your financial year ends. The rule is always 9 months after year-end — and payment is due on the same date as filing. For full guidance see the FTA's official Corporate Tax overview.
Financial Year End CT Filing Deadline Payment Due
31 December 2024 30 September 2025 30 September 2025
31 March 2025 31 December 2025 31 December 2025

Note: Filing and payment fall on the same date. No extensions are currently available under UAE corporate tax law. Source: FTA CT Returns page.
CRITICAL — The 7-Month Waiver Window: If this is your first CT tax period, you can avoid the AED 10,000 late registration penalty by filing your first return within 7 months of the end of that period. This is separate from — and earlier than — the standard 9-month filing deadline. Many SMEs miss this distinction and pay the fine unnecessarily. See the FTA registration guidance for full details.
Who Must File a UAE Corporate Tax Return?
Almost every business entity in the UAE must file. Filing is not limited to profitable businesses or those above the AED 375,000 threshold. The obligation applies to:
- All UAE mainland companies (LLCs, sole establishments, branches)
- Free zone entities — including those qualifying for 0% tax under QFZP status
- Foreign companies with a UAE permanent establishment
- Natural persons (individuals) with business income exceeding AED 1 million
- Businesses that made a loss (to preserve tax loss carry-forward rights)
- Businesses that claimed Small Business Relief (filing is still required)
The FTA has been explicit: registration and filing are mandatory for everyone regardless of tax liability. Good compliance bookkeeping is the foundation for getting this right.
Step-by-Step: How to File Your UAE Corporate Tax Return on EmaraTax
Step 1 — Confirm Your Registration
Log into EmaraTax (tax.gov.ae). Confirm you have a valid Corporate Tax Registration Number (TRN). If not registered yet, do it immediately — the AED 10,000 late registration penalty applies the moment you miss your deadline. Our blog on avoiding compliance penalties covers the broader picture.
Step 2 — Finalise Your Financial Statements
Your CT return must be built on financial statements prepared under IFRS (International Financial Reporting Standards). This is not optional — the FTA expects your return figures to reconcile exactly with your financial statements. Businesses that skip IFRS compliance and use cash-basis summaries are a primary audit trigger. See our guide to streamlining your bookkeeping to ensure your records are IFRS-ready.
Step 3 — Calculate Your Taxable Income
Taxable income is not the same as accounting profit. You must make adjustments:
- Add back non-deductible expenses (see the deductions section below)
- Adjust for exempt income (dividends from UAE subsidiaries, qualifying free zone income)
- Apply any tax loss carry-forwards from prior periods
- Determine whether Small Business Relief applies and elect it if eligible
Step 4 — Determine Your Tax Rate
The UAE corporate tax rate structure for 2025/2026 filings under Federal Decree-Law No. 47 of 2022:
- 0% on taxable income up to AED 375,000
- 9% on taxable income above AED 375,000
- 0% for Qualifying Free Zone Persons (QFZPs) on qualifying income
- 15% Domestic Minimum Top-Up Tax for multinationals with global revenue above EUR 750 million
Step 5 — Complete the EmaraTax Return Form
The EmaraTax portal will guide you through the CT return sections. You will need to input: tax period dates, total revenue, deductible expenses, exempt income, tax loss relief, tax credits, tax payable, and your Small Business Relief election (if applicable).
CRITICAL REMINDER: Small Business Relief is NOT automatic. You must actively elect it on EmaraTax. Many SMEs with revenue under AED 3 million fail to tick this box and overpay tax as a result.
Step 6 — Submit and Pay
Submit the return through EmaraTax before your deadline. Payment is due on the same date. Pay early — the FTA has explicitly warned that last-minute bank transfers may not process in time, leaving you liable for late payment penalties. Need help? Contact Finanshels to handle your CT filing.
Step 7 — Archive Records for 7 Years
Once filed, retain all supporting records — invoices, contracts, bank statements, payroll records, and financial statements — for a minimum of 7 years. The FTA can audit any period within this window. Our guide on bookkeeping best practices includes a records management framework.
UAE Corporate Tax Deductions: What You Can and Cannot Claim
The authoritative source for UAE CT deductions is Ministerial Decision No. 134 of 2023 on the General Rules for the Determination of Taxable Income.
Fully deductible expenses:
- Employee salaries, wages, and benefits (including gratuity provisions per the UAE Labour Law)
- Rent for business premises used wholly for business purposes
- Professional fees for accounting, legal, and consulting services — including Finanshels fees
- Depreciation of business assets under IFRS
- Interest on business loans (subject to the 30% EBITDA cap)
- Marketing and advertising expenses
- Insurance premiums for business coverage
- Training and staff development costs
- IT and software subscriptions used for business
- Bad debt write-offs (with proper documentation of recovery efforts)
Partially deductible expenses:
- Entertainment expenses: capped at 50% of the total amount claimed
- Motor vehicle expenses: only the business portion is deductible
- Net interest expense: deductible only up to 30% of EBITDA; the excess can be carried forward
Non-deductible expenses — common traps:
- Fines and penalties imposed by UAE authorities (including FTA penalties themselves)
- Donations to non-qualifying public benefit entities
- Dividends and profit distributions to shareholders
- Personal expenses of owners or shareholders passed through the business
- Expenses without adequate supporting documentation
- Depreciation claimed in excess of IFRS allowable amounts
- Provisions that do not meet IFRS recognition criteria
The Documentation Rule: The FTA can disallow any deduction not supported by adequate documentation — even if the expense was genuinely incurred. Keep every invoice, contract, and payment receipt. See our guide to bookkeeping importance for a record-keeping framework.
Small Business Relief (SBR): What It Is and How to Claim It
Small Business Relief — introduced under Ministerial Decision No. 73 of 2023 — allows qualifying UAE businesses to be treated as having zero taxable income for a tax period, even if their actual profits exceed AED 375,000.
Who qualifies for SBR in 2026?
- UAE resident businesses with revenue of AED 3 million or less in the tax period
- Not part of a multinational group (consolidated group revenue above EUR 750 million)
- Not a Qualifying Free Zone Person (cannot claim both SBR and QFZP)
- Not an investment fund or regulated financial institution
Important: Small Business Relief applies to tax periods ending on or before 31 December 2026. After that, it sunsets. Use your 2026 filing to plan your 2027 position.
How to elect SBR on EmaraTax:
- Log into EmaraTax
- In the CT return form, navigate to the Small Business Relief section
- Actively select the election — it does NOT auto-apply
- Confirm your revenue is below AED 3 million for the period
- Submit — your tax liability for the period becomes AED 0
Free Zone Businesses: Special Rules You Cannot Afford to Miss
Free zone entities are one of the most commonly mishandled categories in UAE corporate tax. The 0% Qualifying Free Zone Person (QFZP) benefit is defined in Ministerial Decision No. 265 of 2023 (updated by MD No. 229 of 2025).
To maintain QFZP status, your business must:
- Earn qualifying income from qualifying activities
- Not earn non-qualifying income exceeding 5% of total income OR AED 5 million (the de minimis test)
- Maintain adequate substance in the UAE free zone (employees, premises, operations)
- Have audited financial statements (mandatory regardless of size or revenue)
- Not elect Small Business Relief (SBR and QFZP are mutually exclusive)
Common QFZP failure traps: interest income from mainland bank accounts, rental income from mainland property, and service fees from mainland group companies can all push you over the de minimis threshold — eliminating your 0% benefit for the entire period. Need to check your QFZP eligibility? Talk to a Finanshels tax expert.
Related Party Transactions: Transfer Pricing Is Now Enforced
If your business transacts with related parties — including shareholders, directors, sister companies, or group entities — transactions must be at arm's length. Transfer pricing documentation is required when total related party transactions exceed AED 200,000 in a tax period, per Ministerial Decision No. 97 of 2023.
The FTA cross-references CT returns against VAT filings and can identify related-party inconsistencies automatically. This is one of the most active audit triggers in 2026. Our team at Finanshels can review your intercompany transaction structure.
The 5 Most Common UAE Corporate Tax Mistakes in 2026
- Filing without reconciling VAT and CT turnover
If your VAT return shows AED 5 million in supplies but your CT return shows AED 4 million in revenue, the FTA's system will flag the discrepancy. The difference must be explainable and documented.
- Not electing Small Business Relief
SBR is not automatic. Businesses with revenue under AED 3 million who don't actively elect it on EmaraTax pay 9% on profits above AED 375,000 unnecessarily.
- Claiming non-deductible expenses
Owner salaries without employment contracts, entertainment expenses above the 50% cap, and expenses without invoices are the three most commonly disallowed deduction categories. See our post on avoiding penalties through better bookkeeping.
- Free zone businesses not monitoring the de minimis threshold
A single consulting invoice to a mainland client could push your non-qualifying income over 5% of total revenue. Monitor this in real time, not at year-end.
- Last-minute filing and payment
The FTA has explicitly warned that bank transfers submitted on the deadline day may not clear in time. File at least one week early. The late payment penalty — 14% annual interest on the outstanding amount — has no cap.

Frequently Asked Questions
Is corporate tax filing mandatory even if I owe zero tax?
Yes. Every registered UAE corporate tax entity must file a return, even if taxable income is zero, they made a loss, or they are electing Small Business Relief. Non-filing carries the same AED 500 (first offence) / AED 1,000 (repeat) penalty. See the FTA's official returns guidance.
Can I amend my CT return after submission?
Yes, through a Voluntary Disclosure on EmaraTax. Filing a VD before the FTA issues an audit notice results in significantly lower penalties than corrections made during an audit. Our full guide to UAE CT penalties and VD strategy explains how to do this.
What records must I keep for UAE corporate tax?
All financial records, invoices, contracts, bank statements, asset registers, and transfer pricing documentation must be retained for 7 years from the end of the tax period. See our bookkeeping guide for a practical filing system.
Do I need audited financial statements?
Audited financial statements are mandatory for all free zone entities claiming QFZP status. For mainland businesses, audited statements are best practice and will be required if the FTA conducts an audit. IFRS-compliant financial statements are required for all CT return preparation. Finanshels prepares IFRS-ready financials for UAE SMEs.
