Filing Your First UAE Corporate Tax Return

2026-01-18 · 4 min read · By Aureus Worldwide

Your first corporate tax return is a milestone, and for many UAE businesses, the first real test of whether their books are ready. The mechanics run through EmaraTax, but the work that determines whether filing is smooth happens long before you log in: clean accounts, an accurate tax computation, and the right reliefs identified. This guide walks through the first return end to end, from confirming your deadline to submitting, so you file correctly and avoid the penalties that catch unprepared businesses.

Confirm your tax period and deadline first

Everything starts with two dates. Your tax period normally matches your financial year, and your return is due within nine months of the period end. So a 12-month period ending 31 December gives a filing and payment deadline of the following 30 September. A first period can be longer or shorter than 12 months depending on incorporation, so check the period EmaraTax shows for you and confirm anything unusual with the FTA.

You file even if you owe nothing

A core point: registration creates a filing obligation regardless of the result. You must submit a return even if your taxable income is below the AED 375,000 threshold (taxed at 0%), or you are applying Small Business Relief. A nil return is still a return, and missing it triggers a penalty just as a tax-due return would. For the full deadline picture, see our corporate tax deadlines guide.

Start from financial statements

The return is built on your accounting profit. That means your first job is a complete, reconciled set of financial statements for the period, prepared under acceptable accounting standards. If your bookkeeping is behind, catch it up before anything else, a return built on shaky numbers is the most common source of errors and later corrections. Our guide on corporate tax financial statements explains what standard applies and when audited accounts may be expected.

Turn accounting profit into taxable income

Taxable income is not simply your accounting profit. You apply adjustments set out in Federal Decree-Law No. 47 on corporate tax. Common adjustments include:

• Add back disallowed or non-deductible expenses (for example certain entertainment, fines and penalties)
• Apply the interest deduction limitation where relevant
• Exempt income removed from the base (such as qualifying dividends and participation exemption items)
• Tax losses carried forward and offset, within the limits
• Related-party adjustments to reflect arm's-length pricing

The result is your taxable income, to which the rate is applied.

Apply the rate and reliefs

The headline structure is straightforward:

• 0% on taxable income up to AED 375,000
• 9% on taxable income above AED 375,000
• 0% on qualifying income for a Qualifying Free Zone Person, subject to conditions

If your revenue is within the AED 3 million Small Business Relief threshold, you may elect to be treated as having no taxable income for the period, but you still file. Confirm current thresholds and conditions with the FTA, as these are subject to change.

Gather your supporting documents

Before you start the EmaraTax form, assemble:

• Financial statements for the tax period
• Your tax computation showing each adjustment
• Schedules supporting any relief or exemption claimed
• Related-party and connected-person transaction details
• Evidence for the interest deduction position if relevant

Keeping these together is not just for filing, they are your defence if the FTA reviews the period later.

Filing on EmaraTax, step by step

1. Log in to EmaraTax and open your corporate tax registration.
2. Start the return for the relevant tax period.
3. Enter accounting profit and the adjustments to reach taxable income.
4. Claim reliefs or exemptions that apply, with supporting figures.
5. Review the calculated liability carefully against your own computation.
6. Submit the return and pay any tax due by the deadline.
7. Save the confirmation and computation in your records.

First-return mistakes to avoid

• Filing late because the nine-month deadline crept up
• Skipping the return in the belief that 0% or relief means nothing to file
• Submitting on unreconciled accounts
• Missing adjustments, so taxable income is wrong
• No supporting schedules for reliefs claimed
• Overlooking related-party disclosures

Build the discipline now

The first return sets the pattern. Businesses that close their books monthly, reconcile as they go and keep a running tax computation find every subsequent filing routine. Those that scramble once a year repeat the same stress and risk. Treat the first return as the moment to put a proper process in place, and confirm any changeable specifics, rates, thresholds, deadlines, with the FTA before you rely on them.
