Comprehensive Q4 2026 (October 1 – December 31) calendar for USA-based NRIs — immigration deadlines, festivals, sports, tax + compliance, and holiday-travel planning. Compiled September 1, 2026.

Q4 2026 is the most calendar-dense quarter of the NRI year in the USA. Every major festival cluster (Navratri, Diwali, Bhai Dooj, Chhath, Karthigai Deepam) falls in Q4. Every meaningful tax deadline (FBAR extended, 1040 extended, Q4 estimated tax) clusters here. The FY2027 immigration cycle begins Oct 1. Winter India-travel bookings must close by mid-October for reasonable pricing. NFL season peaks + NBA opens + MLB playoffs run.

This is the operator-friendly Q4 monthly hub — bookmark it and return through the quarter as each dated event approaches.
