Self-Assessment Tax: Challan 280 Before ITR
Pay self-assessment tax via Challan 280 minor head 300 — CIN for ITR, 234B risk, and RNOR transition estimates.
The 60-second version
Self-assessment tax clears gap between TDS and actual liability — pay Challan 280 (minor head 300) before e-filing so CPC does not reject return.
Pay before upload — CPC matches challan to PAN
Self-assessment tax = total liability minus TDS/TCS/advance tax paid.
Use minor head 300 on Challan 280 — keep CIN for ITR schedule.
