Fetch GSTR-2B from GSTN

GSTR-2B is the auto-drafted input tax credit statement generated by GSTN on the 14th of every month, based on what your suppliers filed in GSTR-1 / 1A.

When 2B is available

• Generated on the 14th of every month for the previous tax period
• For QRMP (quarterly) taxpayers, also generated on the 14th of the month following the quarter
• Once generated, it does not change - even if suppliers amend their filings later (those changes flow into the next 2B)

Pull 2B into ThynkTax

GST → Reconciliation → New → 2B vs PR

1. Choose client + period
2. Click Fetch 2B from GSTN
3. OTP - if this is the first 2B fetch this session, GSTN sends an OTP to the client's registered mobile. Enter it.
4. The fetch takes 10-30 seconds. Once done, the 2B appears alongside your Purchase Register for the same period.

What 2B contains

• B2B invoices - accepted by your suppliers in their GSTR-1
• CDN - credit notes / debit notes
• ISD - input service distributor credits
• Import of services
• Import of goods (from SEZ)

What 2B does NOT contain

• Invoices your suppliers haven't filed yet → these show up only in 2A (the live mirror)
• RCM (reverse charge) self-invoices - those are in your own books, not 2B
• ITC on advance receipts
