Tally tip: setting up GST in party ledgers and stock items

Clean masters make clean returns: how to capture GSTIN, State, registration type and HSN/rate once in masters instead of fixing vouchers later.

• Company: enable GST, set State, registration type and GSTIN (F11 features / company GST details).
• Party ledgers: record GSTIN/UIN, registration type (regular, composition, unregistered/consumer, SEZ), State and country. Tally uses these to decide IGST vs CGST+SGST and the GSTR-1 table.
• Stock items/groups: set HSN and GST rate, with an applicable-from date when rates change (for example, the September 2025 rationalisation).
• Expense and service ledgers: set SAC/GST applicability and whether ITC is eligible. Mark blocked credits (Section 17(5)) as ineligible.
• Tax ledgers: separate ledgers for input/output IGST, CGST, SGST and cess, and separate RCM ledgers.

Use Tally's GST reports to spot "incomplete/mismatch in information" and fix masters. Every future voucher benefits.
