Set Up GST Registrations and Tax Settings

Set up each GST registration before mapping locations or issuing GST invoices. A registration created during onboarding may already appear here; verify it instead of creating a duplicate.

Add a GST registration

Section titled “Add a GST registration”

Open Settings → Locations & GST and find GST registrations & location coverage.

Create the registration
  1. Select Add GST registration.
  2. Enter the verified GSTIN. Yepsta reads its two-digit state code and validates the complete format and checksum.
  3. Enter Legal name and an optional Trade name.
  4. Choose Registration type: Regular, Composition, Casual taxable person, SEZ or Other.
  5. Choose Filing frequency: Monthly or QRMP.
  6. If applicable, select Annual turnover band and enter previous- and current-financial-year aggregate turnover.
  7. Add a numeric 4-, 6- or 8-digit Default service SAC when it should fill a missing SAC on a service or package invoice line.
  8. Enter Effective from and an optional Effective to date.
  9. Keep Active registration selected when the record should be available for current dated coverage.
  10. Select Add GST registration.

The GSTIN cannot be changed after creation. The legal name, GSTIN and state become part of invoice and compliance identity; filing frequency controls whether compliance periods are monthly or quarterly; turnover details can affect GSTR-1 HSN validation.

There is no default-registration picker. Yepsta resolves the registration from the invoice’s billing location and date through location coverage.

Complete location invoice identity

Section titled “Complete location invoice identity”

Still under Locations & GST, choose a location and complete its name, legal/trade-name override if used, address, city, state name, two-digit state code, pincode, phone and email. Under Invoice Numbering, confirm Invoice Prefix and Invoice Start Number, then select Save Location Settings.

Changing the start number after invoices exist can break expected numbering continuity. Existing invoices retain their captured identity and number.

Choose tax behaviour

Section titled “Choose tax behaviour”

Open Settings → Billing & Tax. Under Tax Engine, choose:

  • Exclusive - tax added separately when entered selling prices exclude GST; or
  • Inclusive - tax included in price when entered selling prices include GST.

Review Round Off, the default payment method and the rest of the visible billing settings, then save. The tax mode is business-wide; products and services do not have a separate inclusive/exclusive switch.

For a GST-enabled invoice, Yepsta compares the registration state with Place of Supply. A match produces CGST and SGST; a different state produces IGST. The person creating the invoice must verify the place of supply.

Edit or end a registration safely

Section titled “Edit or end a registration safely”

Use Edit details for supported profile changes. Use Set end date to end coverage without deleting history. Effective-from cannot be changed after a location mapping exists, and the end date must include every mapping already recorded. A duplicate GSTIN, invalid checksum, inconsistent state or date conflict must be corrected before saving.
