The first return is where the real tax work starts

Most first corporate tax returns expose the gap between a tidy profit and a defensible tax file. Under the Federal Decree-Law No. 47 of 2022, a Taxable Person files and pays within nine months of the end of its Tax Period. The difficult part is deciding what the accounts mean for tax. A consultant pays for itself when the review changes the result, removes a penalty risk or gives the owner a file they can defend. If you would rather not handle this in house, this is what our corporate tax return review covers.

EmaraTax is the last screen, not the work. The return must carry the Tax Period, Tax Registration Number, accounting basis, Taxable Income, relief and loss positions, available tax credits and Corporate Tax Payable. Those entries come from the books and the decisions made before anyone opens the portal. If the accounts are not reconciled, the return only makes the uncertainty official.

The first return is a tax decision, not a form

Begin with the period.

Your first Tax Period may not match the calendar

Dates decide the cost.

The FTA treats a company’s first financial year as its first Tax Period for Corporate Tax. It does not have to be the same as the calendar year. A new company can therefore reach its first filing with a short or extended opening period, depending on the financial year set under the company law.

That distinction decides the deadline. If a company’s financial year ended on 31 December 2025, the FTA states that its return and payment were due by 30 September 2026. At the scheduled 24 September 2026 publication date, that leaves six calendar days.

Start with the accounts, then make tax adjustments

The P&L is only the start.

The FTA describes Taxable Income as the accounting net profit or loss after the adjustments required by the Corporate Tax Law. Those adjustments can cover exempt income, deductions that are not allowed, transactions with Related Parties and Connected Persons, tax losses, elections and other reliefs. A first-return review should show each adjustment, its evidence and its effect on the final number.

The first EmaraTax filing checklist is useful for the portal steps. It is not a substitute for building the tax computation behind the submission.

Owner payments need evidence before deductions

Evidence matters.

Owner and director payments deserve their own review. The FTA’s General Corporate Tax Guide says a payment or benefit to a Connected Person is deductible only to the extent it matches the market value of the service or benefit and is incurred wholly and exclusively for the business. The ledger entry is not enough. Keep the agreement, calculation, approval and proof of work together.

The mistake we see most: an owner sends a spreadsheet of personal or family costs and calls it business expenditure because the payment came from the company account. That creates a tax adjustment, not a deduction. Our owner salary and dividend comparison explains the wider decision, but the first return still needs the underlying evidence.

Small Business Relief still needs a return

An eligible UAE resident person can elect for Small Business Relief where Revenue is no more than AED 3,000,000 in the current and previous Tax Periods. The FTA treats the person as having no Taxable Income for the period, subject to the conditions. The Ministry of Finance extended the relief to Tax Periods ending on or before 31 December 2029.

Relief changes the calculation, not the obligation to file. The FTA confirmed in August 2026 that an eligible business still has to register, submit the simplified return and keep records that support its Revenue and eligibility. The Small Business Relief extension is worth reading before making the election.

The return remains due.

The consultant should hand back working papers

A receipt is not enough.

A useful first-return engagement ends with more than a submitted form. It should leave the owner with the tax-period decision, the adjusted computation, a list of evidence still missing, the relief or election position and a payment handover. The owner should be able to see how the number was built without asking the consultant to reconstruct it.

For a company looking for a corporate tax return review, that handover is the real product. A portal receipt alone tells you very little about the quality of the filing.

Worked example: the adjustment is worth more than the form

Here is the test.

Example, not a quote. Desert Line Trading LLC’s first Tax Period ends on 31 December 2025. Its accounts show AED 900,000 profit. That figure includes AED 80,000 of personal owner costs recorded in expenses, and it omits AED 120,000 of valid business costs that should have been recorded. The review adds back the personal costs and captures the valid costs. Taxable Income becomes AED 860,000.

On the unreviewed AED 900,000, Corporate Tax would be AED 47,250. On AED 860,000, it is AED 43,650. The difference is AED 3,600. If the agreed review fee is below that difference, the tax recovery alone covers it in this example. A fee is not the only return. The company also gets a clearer file and a better chance of answering an FTA query without rebuilding the numbers.

Delay is not a pricing strategy

Do not wait.

The current penalty table incorporates Cabinet Decision No. 129 of 2025, effective 14 April 2026. A late return is AED 1,000 for the first time and AED 2,000 if repeated within 24 months. Late payment is 14% per annum, charged monthly on unsettled tax from the day after the payment due date. Late registration remains AED 10,000, but the FTA waiver initiative can remove that amount when the first return is submitted within seven months of the first Tax Period.

Mixed-use costs have no universal split

The FTA requires a dual-purpose cost to be apportioned so only the business portion is deducted. Its General Corporate Tax Guide says the method must be fair and reasonable, should reflect the underlying activity and may be one of several acceptable methods.

Unsettled: there is no single percentage you can apply to every mixed-use cost. Facts control. Write down the basis for the allocation before filing and keep it with the ledger, contract or usage record.

Ask for the working papers before you appoint anyone

Start with scope.

A first corporate tax return consultant pays for itself when the engagement produces a defensible number, not just a submission receipt. Ask for these points before authorising the work.

1. A written confirmation of the first Tax Period, deadline and payment route.
2. A reconciliation from accounting profit to Taxable Income, with each adjustment explained.
3. A list of elections, owner or Connected Person items, unresolved points and the person responsible for any FTA submission.

A cheap form submission is not the same service. The working papers are what let the owner use the return again next year.
