GST ITC reconciliation, 2B vs purchase register, in seconds.

Why GSTR-2B reconciliation matters

Input Tax Credit (ITC) is often the largest number on a GST return, and it is also the most scrutinised. Under Section 16(2)(aa) of the CGST Act, a registered person can claim ITC on a purchase only if the supplier has reported that invoice and it appears in the buyer's GSTR-2B. That single rule makes monthly reconciliation between your purchase register and 2B non-negotiable — claim credit that isn't in 2B and you invite interest, reversal and notices; miss credit that is in 2B and you overpay tax.

GSTR-2A vs GSTR-2B — which one to reconcile against

GSTR-2A is a dynamic statement that keeps updating as suppliers file returns. GSTR-2B is a static, auto-drafted statement generated once a month. Because ITC eligibility is anchored to 2B, this tool reconciles your books against GSTR-2B, giving you a stable, defensible position for the period before you file GSTR-3B.

What good reconciliation catches

• Ineligible credit booked in your accounts but not reflected in 2B.
• Tax mismatches where the invoice matches but the IGST/CGST/SGST differs.
• Missed credit that suppliers have reported but you haven't recorded.
• Duplicate or mis-keyed invoices surfaced through fuzzy matching.

How often should you reconcile?

Every month, before filing GSTR-3B. Doing it monthly keeps supplier follow-ups timely, prevents credit from lapsing under the annual time limit, and makes your GSTR-9 annual return far easier to close. This tool is built to make that monthly step a two-minute task instead of an afternoon of spreadsheet matching.

Is the tool accurate and private?

All matching runs locally in your browser — your invoice data is never uploaded to any server. The output is a reconciliation you can review, export and attach to your working papers. It supports the professional judgment of a qualified practitioner; it does not replace the final review and sign-off that GST filing requires.
