What is the interest rate on late GST payment?

Is there any waiver for GST late fee?

The government periodically announces late fee waivers through amnesty schemes. For example, returns filed during amnesty periods may have reduced or waived late fees. However, these are special schemes and not regular practice. It's always better to file on time to avoid penalties.

Can I file GST return without paying late fee?

No, late fee must be paid along with the return for it to be accepted by the GST portal. The portal automatically calculates and adds the late fee when you file after the due date. Use TallyPrime to track due dates and file returns on time to avoid these penalties entirely.
