FAQs on Interest Under Sections 234A, 234B, 234C

The sections 234A, 234B, and 234C of the Income Tax Act are taken into account when a penalty needs to be imposed for delayed tax compliance. All these sections are applied in different circumstances:

Section 234A: This section is applied in cases where income tax returns are either filed late or aren’t filed at all. The interest charged under this section stands at 1% per month starting from the due date till the return is filed.

Section 234B: Applied in scenarios where advance tax payments are less than 90% of the assessed tax. This also comes with the charge of 1% monthly interest.

Section 234C: Imposed when the advance tax instalments fall short of the required percentage. The interest rates vary based on the amount paid and the due dates.
