The UAE’s Corporate Tax regime has now moved from theory to reality.
For some of the UAE businesses, 2026 is the year of filing their first Corporate Tax return — covering Financial Year 2025.
Thousands of companies are currently:
- Closing their 2025 books
- Finalizing accounts
- Preparing Corporate Tax returns
- Ensuring compliance with Federal Tax Authority (FTA)
If you’re in the same position — this guide walks you through exactly how to file UAE Corporate Tax for FY-2025, what documents you need, deadlines to track, and how to avoid costly penalties.
And if you prefer to outsource everything — ProAct Chartered Accountants handles bookkeeping, accounts finalization, and Corporate Tax filing under one roof.
Who Must File Corporate Tax for FY-2025?
You must file a Corporate Tax return if:
✔ Your UAE company is licensed (Mainland or Free Zone)
✔ You conducted business activities in 2025
✔ You are registered for Corporate Tax with the FTA
This applies to:
- Mainland LLCs
- Free Zone companies (including DMCC, IFZA, RAKEZ, Meydan, SPC, etc.)
- Branches of foreign companies
Even Free Zone companies must file — regardless of whether they qualify for 0% Free Zone tax benefit.
When Is the Corporate Tax Filing Deadline for FY-2025?
For most companies:
Deadline: 9 months from financial year-end
Example:
If your FY-2025 ended on 31 December 2025
👉 Corporate Tax return deadline = 30 September 2026
Missing this deadline triggers FTA penalties, which we’ll cover below.
Step-by-Step Process to File UAE Corporate Tax for 2025
Step 1: Close Your 2025 Books of Accounts
Before filing tax, you must prepare:
- Profit & Loss Statement
- Balance Sheet
- General Ledger
- Supporting schedules
If your bookkeeping is incomplete — tax filing cannot proceed.
👉 ProAct provides year-end bookkeeping & accounts finalization to ensure tax-ready books.
Step 2: Apply Accounting Standards
Your financials must follow:
- IFRS
or - IFRS for SMEs
Improper accounting treatment leads to incorrect taxable income calculations.
Step 3: Identify Corporate Tax Adjustments
Not all accounting profits are taxable. Adjustments include:
- Disallowed expenses
- Related-party transaction adjustments
- Depreciation differences
- Provisions and accruals
- Exempt income
This is where most DIY filings go wrong.
Step 4: Apply Small Business Relief (If Eligible)
If your revenue is ≤ AED 3 million, you may qualify for:
✅ 0% Corporate Tax under Small Business Relief
(valid for tax periods ending on or before 31 December 2026)
Many SMEs miss this relief due to improper filing.
Step 5: Check Free Zone 0% Eligibility
Free Zone companies can retain 0% tax if:
✔ Qualifying income conditions met
✔ Non-qualifying revenue ≤ 5% or ≤ AED 5 million
✔ Proper substance maintained
✔ Transfer pricing documentation maintained
Even when eligible for 0% — filing is mandatory.
Step 6: Access FTA Corporate Tax Portal
You must:
- Log in to FTA EmaraTax portal
- Access Corporate Tax section
- Prepare return form for FY-2025
Step 7: Upload Financials & Supporting Schedules
FTA may requires:
- Financial statements
- Tax computation
- Related-party disclosures
- Free Zone declarations (if applicable)
Step 8: Submit Return and Pay Tax Due
After review:
- Submit return
- Pay Corporate Tax liability (if any)
Return acknowledgment is generated instantly.
Documents Required for Corporate Tax Filing
✔ Trade License
✔ Financial Statements (FY-2025)
✔ Trial Balance & Ledger
✔ Bank Statements
✔ VAT Returns (if applicable)
✔ Related Party Transaction details
✔ Free Zone compliance documents
Corporate Tax Penalties for Late Filing
| Non-Compliance | FTA Penalty |
|---|---|
| Late filing of return | AED 500 – AED 1,000 per month |
| Late tax payment | 14% annual interest |
| Incorrect return | 1% monthly interest for self-corrections; 15% flat penalty plus interest if found during an audit. |
Penalty exposure grows quickly — especially for first-time filers.
