Accounting — 2026 Compliance Calendar
2026 is a genuinely compliance-heavy year for UAE businesses — Small Business Relief ends 31 December, e-invoicing enforcement is already live, and Corporate Tax and VAT deadlines keep running regardless. FMCA tracks every deadline that applies to your business on one calendar, so filings get prepared ahead of time instead of discovered the week they're due.
Reviewed by FMCA's Senior Accounting Advisory Team — CPAs and former Big Four auditors serving 500+ UAE and KSA SMEs.
Four categories of deadline every UAE business needs on one calendar this year.
Returns due 9 months after the end of each entity's financial year — the exact date depends on your specific year-end.
Monthly or quarterly depending on registration category, with penalties applying from the first day a return is late.
The relief window closes at year-end — businesses relying on it need a transition plan for standard 9% filing in 2027.
Phased enforcement is already underway — the applicable phase and requirements depend on business size and sector.
2026's deadlines carry real, specific penalties — this isn't a year to track compliance informally.
A missed Corporate Tax filing deadline triggers a fixed penalty immediately, with additional penalties accruing the longer it remains unfiled.
VAT penalties apply from the first day a return is late, and escalate the longer the filing remains outstanding.
Invoices that don't meet the applicable e-invoicing phase requirements can be treated as non-compliant, with knock-on VAT implications.

Businesses operating in both markets are tracking two separate compliance calendars, not one.
Our Approach
Tracking deadlines is only useful if someone acts on them ahead of time. FMCA's tax and accounting teams monitor every applicable deadline and start preparing filings before the date arrives, not the week it's due.
How We Work
Illustrative scenarios based on the kind of work we do — not descriptions of specific named clients.
A business relying on Small Business Relief was flagged early for 2027 transition planning, well ahead of the 31 December 2026 expiry.
Corporate Tax, VAT, Zakat and Fatoora deadlines across both markets consolidated into a single tracked calendar, closing a gap where KSA deadlines had previously been missed.
System readiness for the applicable e-invoicing phase was confirmed and tested weeks before the enforcement date, rather than discovered as non-compliant after the fact.
