How to do monthly GST reconciliation (GSTR-2B vs your books)

Monthly reconciliation protects your input tax credit and prevents nasty surprises at year end. It is a short, repeatable routine once you know the steps.

Step 1: Download GSTR-2B

Each month, pull your auto-generated GSTR-2B from the GST portal. It lists the input tax credit available based on what your suppliers filed.

Step 2: Match it to your purchase register

Compare 2B line by line with the purchase invoices in your books. Tick off every invoice that matches on GSTIN, invoice number, date and tax amount.

Step 3: Flag the mismatches

Missing in 2B means the supplier has not filed; missing in your books means you forgot to record a purchase. Wrong amounts need correcting. List every gap.

Step 4: Chase suppliers who have not filed

For invoices missing from 2B, remind the supplier to file. Your credit depends on their filing, so a quick nudge protects your money.

Step 5: Reconcile sales too

Match your sales register to what you reported in GSTR-1. Consistent sales, purchase and return figures keep you notice-free.

Frequently asked questions

Why reconcile every month?

Because input tax credit is time-bound and depends on suppliers filing. Monthly checks catch missing invoices while there is still time to fix them, rather than losing the credit.

What is GSTR-2B?

A static, auto-drafted statement of the input tax credit available to you for a month, based on your suppliers' filings. It is the benchmark you reconcile your purchases against.

What if a supplier never files?

You may lose the credit on that invoice. Prevent it by reconciling monthly, chasing early, and preferring suppliers with a clean filing record.
