Rules behind the schedule
- Who pays: anyone whose net tax (after TDS) is ₹10,000+ — salaried with full TDS usually owe nothing.
- Quarterly cuts: 15% / 45% / 75% / 100% cumulative — miss them and 234B/234C interest (1%/month) applies.
- Capital gains: can't predict March gains? Shortfalls from CG are excused if paid in the next instalment.
- How to pay: e-pay on incometax.gov.in (challan 280) → quote in ITR → interest saved is return earned.
