How to File a UAE Corporate Tax Return: Step-by-Step Guide for 2026

UAE corporate tax (CT) came into effect for financial years starting on or after 1 June 2023. For most businesses operating on a calendar-year basis, this means the first CT return was due in 2025. The second cycle is now underway.

This guide covers how to actually file the return through EmaraTax, what you need to prepare, the key deadlines, and the mistakes that catch businesses out.

If you want background on the tax itself — rates, exemptions, and what counts as taxable income — see the UAE Corporate Tax Guide first. This guide focuses specifically on the filing process.

Who Needs to File

Almost every business registered in the UAE needs to register for corporate tax and file a return, including:

• UAE mainland companies
• Free zone companies (including those claiming the 0% Qualifying Free Zone Person rate)
• Foreign companies with a permanent establishment in the UAE
• Individuals operating a business under a mainland or free zone licence with annual revenue above AED 1 million

Free zone companies are not exempt from filing. Even if your free zone income qualifies for the 0% rate, you still need to register with the FTA and submit an annual return. The exemption applies to your tax rate, not your filing obligation.

Small businesses under AED 3 million revenue may elect Small Business Relief for tax years 2023, 2024, and 2025. If you elect this relief, your taxable income is treated as zero and you pay no CT. But you still need to file a return and make the election formally.

Key Deadlines

The CT return deadline is 9 months after the end of your financial year. For calendar-year businesses:

If your financial year ends on a different date (e.g., 31 March or 30 June), count 9 months from that date.

Tax payment is due on the same date as the return. Unlike some tax systems, there is no separate payment deadline. You file and pay at the same time.

Late filing penalty: AED 500 per month for the first 12 months, then AED 1,000 per month after that.

Step 1: Register for Corporate Tax on EmaraTax

If you have not already registered, go to EmaraTax and create or log in to your FTA account. EmaraTax is the Federal Tax Authority’s online portal and is where all UAE tax filings are managed.

Most businesses that were already registered for VAT have an existing FTA account. You need to add CT registration to that account. If you are not registered for VAT and this is your first FTA interaction, you will create a new account.

To register for CT, you need:

• Trade licence (mainland or free zone)
• Passport and Emirates ID of the authorised signatory
• Company details: registered address, business activity, financial year start date

Registration deadline: Within 9 months of the end of your first financial year. For businesses with a financial year ending 31 December 2024, the registration deadline was 30 September 2025.

If you missed registration, register now. Penalties for late registration start at AED 10,000.

Step 2: Prepare Your Financial Statements

The CT return is based on your audited (or reviewed) financial statements for the year. You need:

• Profit and loss statement (income statement)
• Balance sheet
• Notes to accounts (for larger businesses)

Do you need an audit? The FTA requires that financial statements used for CT purposes are prepared in accordance with IFRS or IFRS for SMEs. An audit is not legally mandatory for all businesses under CT rules, but:

• Free zone companies claiming the Qualifying Free Zone Person (QFZP) status must have audited financial statements
• Companies with revenue above AED 50 million should strongly consider an audit
• Any business claiming complex deductions or group relief should have professionally prepared accounts

For a small sole-trader or SME with straightforward accounts, well-prepared management accounts may be sufficient. But “well-prepared” means correct revenue recognition, proper expense classification, and a clear audit trail — not just a bank statement summary.

Step 3: Calculate Your Taxable Income

Taxable income is not the same as accounting profit. You start with your accounting profit and then make adjustments.

Common adjustments

Add back (non-deductible items):

• Personal expenses run through the business
• Fines and penalties (including FTA penalties)
• Donations to non-approved charities (donations to FTA-approved public benefit organisations are deductible)
• 50% of entertainment and meals expenses (the other 50% is deductible)
• Excess interest above the general interest limitation rule threshold (30% of EBITDA for large groups)

Deduct (additional reliefs):

• Small Business Relief election (if eligible — brings taxable income to zero)
• Depreciation adjustments if your accounting depreciation differs from the tax treatment
• Carried-forward tax losses from prior years (you can carry losses forward indefinitely)

Transfers within a qualifying group: If you have multiple UAE entities in a corporate group, you may be able to claim group relief or tax consolidation. These are advanced elections and most SMEs will not need them.

The net result after adjustments is your taxable income.

Step 4: Apply the Tax Rate

Important: The 0% threshold applies to the first AED 375,000, not to the whole income. If your taxable income is AED 500,000, you pay 9% on AED 125,000 = AED 11,250.

Free zone QFZP rate: If you meet all the conditions for the Qualifying Free Zone Person status (the 9-point test including physical presence, core income activities, substance requirements, no mainland PE), your qualifying income is taxed at 0%. Any non-qualifying income is taxed at 9%.

Step 5: File the Return on EmaraTax

Log in to EmaraTax at eservices.tax.gov.ae. Navigate to the Corporate Tax section and select “File CT Return.”

The return form asks for:

1. Entity details — auto-populated from your registration
2. Financial year — confirm the period
3. Revenue — total revenue from your P&L
4. Accounting profit/loss — pre-tax profit from your financial statements
5. Adjustments — a series of fields for each add-back and deduction type (see Step 3 above)
6. Small Business Relief election — tick if applicable
7. QFZP status (free zone companies only) — confirm qualifying income split
8. Tax losses — any carried-forward losses from prior years
9. Taxable income — calculated automatically
10. Tax payable — calculated automatically

You attach supporting documents including your financial statements and, if claiming QFZP status, documentation supporting your qualifying status.

Review carefully before submitting. Once submitted, the return cannot be amended through self-service. Corrections require a voluntary disclosure through EmaraTax, which carries a minimum AED 1,000 fee.

Step 6: Pay the Tax Due

Payment is made through EmaraTax at the time of filing. Options include:

• e-Dirham (government payment card, available at ENBD and other banks)
• Bank transfer to the FTA’s designated account
• Credit/debit card (VISA or Mastercard, though a 2-3% processing fee may apply)

There is no instalment option. Payment is due in full by the return deadline.

Keep the payment confirmation reference number. The FTA system updates within 1-3 business days.

Common Mistakes

Filing late because of accounting delays. The 9-month deadline gives you time, but many businesses do not start preparing accounts until month 7 or 8 and then run into auditor availability issues. Start earlier.

Treating free zone status as automatic exemption. Being in a free zone does not make you exempt from CT or from filing. The QFZP status has specific conditions that need to be met and documented each year.

Not registering Small Business Relief. Businesses under AED 3 million revenue can claim zero CT for 2023, 2024, and 2025 under the transitional Small Business Relief. But you must formally elect it in the return. It is not automatic.

Running personal expenses through the company. The FTA expects personal expenses to be identified and added back. If your accounts contain significant mixed-use expenses (phone, car, travel), get these properly classified before filing.

Ignoring prior-year losses. If your business made a loss in its first CT year, that loss can be carried forward to offset future taxable income. Do not forget to include it in the loss schedule on EmaraTax.

Missing the VAT-CT link. VAT-registered businesses have their revenue visible to the FTA through VAT returns. Large discrepancies between VAT-declared revenue and CT-declared revenue will attract scrutiny. The two filings need to be consistent or the differences need clear explanation (e.g., exempt supplies, out-of-scope items).

What Happens After You File

The FTA does not issue a confirmation letter for routine returns. You will see the status update on EmaraTax within a few days.

The FTA has audit powers and can select businesses for CT audits. They have 5 years from the filing deadline to open an audit (extendable in fraud cases). Keeping well-organised records — financial statements, invoices, contracts, bank statements — is essential.

If the FTA disagrees with your filing, they issue a tax assessment. You have 40 business days to object through EmaraTax. The formal objection process is a separate guide topic, but the key point is: keep your supporting documents and respond on time.

Hiring Help

For a simple single-entity UAE business with straightforward revenue, a competent UAE accountant or tax agent can handle CT registration and filing for AED 2,000-5,000 per year. Larger or more complex filings (group companies, QFZP status, significant adjustments) cost more.

Look for a UAE-licensed tax agent registered with the FTA. The FTA publishes a list of registered tax agents on their website.

Summary

Filing a UAE corporate tax return involves six steps: register on EmaraTax, prepare financial statements, calculate taxable income with the relevant adjustments, apply the 9% rate (above AED 375,000), submit through EmaraTax, and pay on the same day.

The deadline is 9 months after your financial year end. Late filing costs AED 500/month. Free zone companies must file even if they qualify for the 0% rate. Small businesses under AED 3 million revenue can elect Small Business Relief — but only if they formally do so in the return.

The process is not complex for most SMEs, but it rewards early preparation and clean accounting records.

If your books are not in good shape before filing season, the clean-up costs more than the software would have. Odoo via WireApps handles invoicing, expenses, and financial reporting for UAE SMEs — with VAT and corporate tax structures already configured for FTA requirements.
