⚡ In shortValidate your GSTR-3B figures before you file — the tool checks that output tax, input tax credit and cash payment reconcile, and flags any short payment that would attract interest. Free, deterministic, instant. Enter your total output tax, input tax credit (ITC) and cash paid. The validator computes the net liability (output tax minus eligible ITC) and confirms your cash payment matches it. It flags a short payment (which attracts 18% interest under Section 50) and warns if ITC exceeds output tax (the excess carries forward). It does not file for you — it catches mistakes before you do.

Frequently asked questions

Why validate before filing GSTR-3B?

A short payment or an ITC mismatch is the most common reason for a GST notice and 18% interest. A quick check before you file saves time and money.

Does this submit my return?

Is this professional advice?

No. It is a deterministic arithmetic check. Confirm complex positions with a GST practitioner.
