- Interest: ₹20,000 × 18% ÷ 365 × 30 days = ₹296.
- The government sometimes waives late fees. Check the GST portal for your return.
- How much it matters to you: 7 out of 10. It only changes the order on your statement.

Questions people ask
Is this tax advice?
No. We show the published fee and interest on your own numbers. For your situation, check the GST portal or ask a tax professional.
Why does the cap matter?
Because past a point the fee stops growing. Your cap depends on your turnover, so your real fee may be lower than shown.
