Penalty for late filing: QAR 500 per day, capped at QAR 180,000 per year.
Monthly (by the 16th) – Withholding Tax (WHT)
Payments made to non‑residents without a permanent establishment in Qatar must be reported and remitted by the 16th of the following month.
Within 30 Days of Contract – Capital Gains Tax (CGT)
For disposals of real estate, shares, or business assets, unregistered taxpayers must file a CGT return within 30 days of the contract or disposal date (whichever is earlier).
Global & Domestic Minimum Tax (DMTT)
Watch for updates from the General Tax Authority (GTA) on the Global Anti‑Base Erosion (GloBE) rules. Large multinationals may face extended reporting windows (typically 15–18 months after fiscal year‑end) during the transition year.
