UAE Corporate Tax year-end checklist for SMEs

For a calendar-year taxpayer, the tax period ending 31 December 2026 is almost complete. The filing deadline, assuming a 9-month window, is 30 September 2027 — but year-end is not just a filing-deadline trigger. The decisions and records that make a smooth return happen now, in November and December, not next summer. This is the short checklist we work through with SMEs each year.
To be clear
31 December 2026 is a period end, not a filing deadline. The Corporate Tax return is normally due 9 months after the end of the relevant tax period. For a calendar-year taxpayer, that means 30 September 2027 under the current law.
1. Close the books cleanly
Tax adjustments are only as good as the accounting number they start from. Before any tax work begins, close the ledger for the period. For most SMEs, that means:
- Bank, cash and credit-card reconciliations completed to 31 December 2026.
- Accounts receivable and payable aged and reviewed; stale balances investigated and cleared or provisioned.
- Inventory counted and valued; obsolete stock written down where appropriate.
- Fixed-asset register reconciled to the general ledger; additions and disposals recorded.
- Payroll and end-of-service balances reflected through December.
- Prepayments, accruals and deferred-income adjustments posted.
If your business will be audited, the audit timeline usually sets the practical cut-off. If not, allow at least four weeks after period-end to close the books before starting the tax adjustments.
2. Walk the accounting-to-tax bridge
Taxable income is not the same as accounting profit. The Corporate Tax return starts from your accounting result and then applies permanent and temporary differences. The adjustments we see most often for SMEs:
- Non-deductible expenses. Fines, certain donations, excessive entertainment and non-business costs need to be identified and added back.
- Depreciation and tax amortisation. Accounting depreciation and tax amortisation may differ. Document the basis you have used.
- Interest limitation. If the entity has related-party or third-party financing, confirm whether the general interest deduction limitation applies.
- Exempt income. Dividends and other exempt income need to be identified and removed from taxable income.
- Prior-year tax losses. Carried-forward losses from the first CT period onwards can offset taxable income, subject to the statutory conditions on utilisation.
Document each adjustment with a short working paper. "Why we did this" matters more than "what we did" if the return is ever reviewed.
3. Related parties — even without a full TP study
Arm's-length obligations apply to any taxpayer with related-party transactions, not just groups above the master/local file thresholds. The mandatory master and local file documentation thresholds under Ministerial Decision 97 of 2023 are taxpayer revenue of at least AED 200 million or MNE consolidated revenue of at least AED 3.15 billion. Below those thresholds, you still need to be able to defend each related-party transaction as arm's length.
A practical SME version: list every transaction with a related party (owner, group company, director's family, controlled entity) during the period, with amounts and basis. Keep the list with the tax file. If a transaction looks hard to justify at arm's length, that is a flag to review now rather than at filing.
4. Small Business Relief: eligibility and election
If the entity has revenue of AED 3 million or less in the current period and in all prior tax periods ending on or before that date, SBR is available for a tax period ending on or before 31 December 2026. Three points to confirm:
- Revenue figure for the current period, measured on the SBR basis (gross income before expenses).
- Revenue figure for every prior tax period back to the first CT period for the entity. One prior-period breach disqualifies you now, even if revenue has since dropped.
- Resident status, no QFZP election, no large-MNE constituent-entity position.
If SBR applies, the election is made inside the return — and a simplified return is still filed. SBR does not remove the filing obligation. See our SBR explainer for the full rules.
5. Free-zone flag check
Free-zone companies claiming the 0% QFZP rate should confirm that every QFZP condition has been met across the whole period: substance in the free zone, qualifying income only (or non-qualifying revenue within the de minimis limit), no standard-regime election, arm's-length related-party transactions and audited financial statements for the period.
The de minimis limit is the lower of 5% of total revenue or AED 5 million. A single large non-qualifying contract can breach the limit, with consequences for the whole period and the four following periods. If you are near the limit, a short QFZP assessment before year-end is cheaper than a wrong 0% position on the return.
6. Plan the filing handoff
Even with a September 2027 deadline, the practical queue matters. Our view of a sensible timeline for a calendar-year SME:
- January–February 2027: close the books, draft adjustments, confirm related-party list and SBR/QFZP position.
- March–May 2027: audit (if applicable) and tax reviewer walk-through. Resolve open items.
- June–July 2027: draft return, reviewer sign-off, client approval.
- August 2027: file. Leaving filing until the last week of September is unnecessary risk.
Three things not to do
- Do not treat SBR as a reason to skip registration or filing. It is not.
- Do not back-date Q4 transactions after year-end to shift revenue between periods. This creates both accounting and tax exposure.
- Do not rely on generic "tax calendar" pages that quote one deadline for every business. Confirm your tax period and assigned deadline on EmaraTax. Our tax calendar is a starting point, not a substitute for the portal.
Where TaxSey can help
The TaxSey Corporate Tax service covers registration (AED 2,000) and annual return preparation (from AED 3,500) with a named preparer and reviewer. For free-zone entities, we usually run the QFZP assessment before filing rather than after. For the records that feed the return, bookkeeping is a separate scope that we quote based on your transaction volume.
