Quick Answer: How to Create a Voucher Type Class in Tally Prime?

Go to Gateway of Tally > Alter > Voucher Type > Select Voucher Type (Sales/Purchase). Under 'Name of Class', enter a class name (e.g. GST Sales). Configure default accounting allocations, add tax ledgers (CGST, SGST, IGST), and add an Invoice Rounding ledger. Save with Ctrl+A.

  • Eliminates manual tax & round-off ledger selection during invoice entry.
  • Supports separate classes for Local GST Sales, Interstate Sales, and Exports.
  • Invoice Rounding ledger automatically adjusts decimal fractions to nearest Rupee.
  • Saves up to 60% of data entry time per invoice in manual billing.
