Corporate Tax deadlines are easier to manage when you start from the company financial year end. The return and payment deadline normally falls 9 months after that date.
Simple Deadline Formula
Take the end date of the tax period, then add 9 months. That is the practical filing target for most UAE companies.
Examples
- Financial year ending 31 December 2025: deadline usually 30 September 2026
- Financial year ending 31 March 2026: deadline usually 31 December 2026
- Financial year ending 30 June 2026: deadline usually 31 March 2027
What to Do 90 Days Before the Deadline
- Close bookkeeping to year end
- Reconcile bank and card accounts
- Review deductible and non-deductible expenses
- Check reliefs and elections
- Prepare financial statements
- Draft the Corporate Tax return
The deadline is a filing date, not a bookkeeping start date. Start the accounting close well before the final month.
What This Looks Like in Practice
The nine-month rule is simple, but businesses still miss it because the accounting close starts too late. The return deadline should be the end of the process, not the first reminder to reconcile the bank.
Records to Keep Before You Decide or File
- Financial statements, trial balance, and general ledger for the tax period
- Tax adjustment schedule showing deductible and non-deductible items
- Related-party, owner-payment, loan, and transfer-pricing support
- EmaraTax registration, filing, relief, and payment confirmations
Review Questions for the Owner
- Is the accounting profit reliable enough to be the starting point for tax?
- Have reliefs, exemptions, and free zone positions been documented instead of assumed?
- Are owner and related-party payments supported at arm's length?
- Can the business explain each material tax adjustment in plain English?
Mistakes That Make This Expensive
- Preparing the Corporate Tax return from unreconciled bookkeeping
- Treating owner drawings, dividends, and salary as the same thing
- Assuming no tax payable means no registration, filing, or records obligation
Practical Next Step
Work backwards from the filing date: close accounts 90 days before, review tax adjustments 60 days before, and approve the return before the final month.
Keep a short working paper with the facts, dates, assumptions, and documents used. It makes future filing, review, or handover much easier.
