   Facts

   If your own tax payable after TDS was more than ₹10,000, advance tax was due during the year. CPC charges interest under Sec 234B and 234C when advance tax was not paid or was paid late, even if you paid the balance before filing.

   Provisions and law

   • Sec 234B, Income-tax Act 1961 (now Sec 424)Interest of 1% a month when advance tax paid (including TDS) is less than 90% of the tax assessed.
   • Sec 234C, Income-tax Act 1961 (now Sec 425)Interest of 1% a month for each instalment of advance tax that was short or late.
   • Sec 143(1), Income-tax Act 1961 (now Sec 270(1))After processing your return, CPC sends an intimation showing tax payable or refund due, after only limited adjustments.

   Analysis

   Say your tax after TDS was ₹40,000 because of FD interest and you paid it as self-assessment tax in July. CPC will charge 234C for each missed instalment and 234B for the months from April till payment. That is correct law, not an error, and you should pay it. It becomes an error only if CPC ignored an advance tax challan you paid, in which case you correct the credit through rectification.
