GST compliance requires accurate storage of the supplier GSTIN in Oracle Fusion. Fusion offers two levels for storing vendor GST:

1.Party Tax Profile Level
2.Party Address Level

Knowing where to store and when ensures:
    Correct GST determination
    Accurate tax calculation during AP invoice validation
    Seamless statutory reporting and compliance.

1️. Storing vendor GST at party tax profile level

What it is:

• Linked to the Supplier Party (Supplier Header) in Oracle Fusion.
• Represents GST registration applicable across all supplier sites under the same supplier.

 Navigation: Procurement > Suppliers > Manage Suppliers

• At the Profile level, go to GST Registration under Tax Registrations, click on add (+), and enter:
  • Registration Number
  • Registration Type
  • Effective Dates
  • Tax Regime Code

This profile is mandatory for tax determination and correct place-of-supply processing.

When to use:

• When the supplier has only one GSTIN for all transactions across India.
• When your organization uses a simplified GST management approach without a state-wise breakup.

2️. Storing vendor GST at the address level

What it is:

• Linked to the Supplier Site (Supplier Address Level).
• Allows maintaining state-wise GST registrations for the same supplier.

Navigation: Procurement > Suppliers > Manage Suppliers > Supplier Address

For Example:- The Company operates in Delhi with a GSTIN for Delhi and Rajasthan with a GSTIN for Rajasthan. Select any address and edit, at the address detail click on tax registration under transaction tax, and click on the add button

When to use:

• When the supplier has multiple GSTINs in different states.
• If transactions need a site-specific GSTIN application for correct place-of-supply handling.
• Useful for large vendors with operations in multiple states and state-wise billing.

Which one to choose and when?
