Comparison of section 406 'Payment of advance tax by assessee on his own accord.' between the Income-Tax Act, 2025 (as passed) and the Income-Tax Bill, 2025 (as originally introduced)

Advance tax obligation: taxpayers must self estimate income and pay instalments, with permitted adjustments to remaining payments.

Every person liable to pay advance tax must remit instalments based on the assessee's own estimate of current income (the specified sum) and the tax thereon, calculated by the prescribed method and paid at prescribed instalment percentages and due dates; taxpayers may increase or reduce amounts in remaining instalments to reflect revised estimates, and the clause itself defines specified sum but is silent on exceptions, enforcement, interest, penalties and procedural recordkeeping.
