UAE Corporate Tax Returns: Timeline, Requirements, and Penalties

Every business subject to UAE corporate tax must file a corporate tax return with the FTA for each tax period. This applies regardless of whether you owe tax — even if your taxable income is zero (because of small business relief or QFZP status), you still need to file.

The corporate tax return reports your taxable income, any adjustments, the tax calculation, and any claims for relief or exemptions. Think of it as the corporate equivalent of the VAT return, but annual instead of quarterly.

Corporate tax returns must be filed within 9 months from the end of the relevant tax period.

For most companies with a standard January-December financial year:

• Tax period: 1 January 2025 to 31 December 2025
• Filing deadline: 30 September 2026

For companies with other financial year ends (e.g., April-March):

• Tax period: 1 April 2025 to 31 March 2026
• Filing deadline: 31 December 2026

The 9-month window is generous by international standards, but do not wait until the last month. The companies that file cleanly are those that prepare throughout the year.

Before you can file a return, you must be registered for corporate tax with the FTA. This is a separate registration from VAT.

All taxable persons must register, including:

• UAE mainland companies
• Free zone companies (even QFZPs expecting 0% tax)
• Foreign companies with a permanent establishment in the UAE

Registration is done through the FTA's EmaraTax portal. The deadline for registration varies based on when your license was issued — check the FTA's published schedule. Late registration triggers a penalty of AED 10,000.

Upon registration, you receive a Corporate Tax Registration Number, which is distinct from your VAT TRN.

To prepare your corporate tax return, you need:

• Audited financial statements — mandatory for QFZPs and recommended for all
• Trial balance and general ledger — the detailed transaction record for the period
• Revenue breakdown — total revenue, split between qualifying and non-qualifying income (for QFZPs)
• Expense analysis — total expenses, with non-deductible items identified
• Depreciation schedules — asset-by-asset depreciation for the period
• Transfer pricing documentation — if you have related-party transactions above the disclosure threshold
• Small Business Relief election — if claiming relief for revenue under AED 3 million
• QFZP election and supporting documentation — if claiming qualifying free zone person status

The return itself is filed through the FTA portal. The exact form and fields are prescribed by the FTA and may evolve as the corporate tax regime matures.

The FTA imposes significant penalties for corporate tax non-compliance:

• Late filing: AED 500 per month for the first 12 months, increasing to AED 1,000 per month thereafter. This can accumulate quickly
• Late payment: A percentage-based penalty on the unpaid tax amount (the specific rates are detailed in Cabinet Decision No. 75 of 2023)
• Late registration: AED 10,000
• Incorrect return: Penalties apply if the FTA identifies that you under-reported taxable income. Voluntary disclosure mitigates but does not eliminate the penalty

The penalties for corporate tax are separate from and additional to VAT penalties. A company that is late on both VAT and corporate tax faces parallel penalty regimes.

Steps to make corporate tax filing as smooth as possible:

• Close your books monthly — do not let 12 months of transactions pile up for year-end
• Reconcile all bank accounts before year-end — discrepancies found during tax preparation are expensive to fix
• Classify expenses correctly during the year — identifying non-deductible expenses at filing time requires reviewing every transaction
• Track related-party transactions — if you have transactions with group companies or shareholders, document them at arm's length
• Engage your auditor early — ideally at the start of the financial year, not three months before the filing deadline
• Use software that supports corporate tax — Maya Finance tracks qualifying vs non-qualifying income, calculates depreciation, and prepares the data your auditor and tax advisor need for the corporate tax return
