UIN Holder in Invoice: Complete Guide for Tax-Exempt Entities

When invoicing certain special entities in India, you'll need to handle their Unique Identification Number (UIN). Understanding UIN and how it appears on invoices is crucial for both sellers and tax-exempt organizations to ensure proper GST compliance.

This guide explains everything about UIN holders, how to handle UIN in invoices, and how LEDGERS simplifies the process.

What is UIN (Unique Identification Number)?

UIN (Unique Identification Number) is a unique 15 digit identification number assigned by GST authorities to an individual who does not need to register for GST, but can get a refund on GST paid. Most businesses will receive a standard GSTIN which they will use to collect tax from customers; however, UIN is only available to organizations that are exempt from registering under GST and are only entitled to claim Input Tax Credit (ITC) for their purchases. The structure of UIN is similar to a GSTIN (both are composed of 15 alpha numeric characters), but UIN has a totally different purpose.

Who Gets a UIN?

UIN is issued only to notified entities exempt from GST registration:

• United Nations and Specialized Agencies: UN and its specialized agencies including WHO, UNICEF, UNESCO, UNDP, and others operating in India.
• Consulates and Embassies: Foreign diplomatic missions, consulates general, high commissions, and embassies established in India.
• International Organizations: Other international organizations notified by the government, including multilateral financial institutions and inter-governmental organizations operating under bilateral or multilateral agreements with India.

These entities are not engaged in regular business activities subject to GST, make purchases in India on which GST is charged, are entitled to claim refunds of GST paid, and operate under special exemptions or international agreements.

UIN vs GSTIN: Key Differences

GSTIN holders must file regular GST returns, collect tax on outward supplies, pay tax liability, and maintain complete GST compliance.

UIN holders do not file regular GST returns, do not collect tax on any supplies, only claim refunds on GST paid, and file refund applications instead of tax returns.

When you invoice a GSTIN holder, you show their 15-digit GSTIN and charge applicable GST. When you invoice a UIN holder, you show their 15-digit UIN and still charge applicable GST, but the UIN holder will later claim a refund of that GST.

Mandatory Invoice Fields for UIN Holders

• UIN Number: The complete 15-digit Unique Identification Number of the buyer.
• Name and Address: Complete registered name and address of the UIN holder entity.
• Invoice Number and Date: Sequential invoice number and date of issue.
• Description of Goods or Services: Detailed description including HSN/SAC codes.
• Quantity and Unit: Quantity supplied and unit of measurement.
• Taxable Value: The base value before adding GST.
• GST Rate and Amount: Applicable CGST, SGST/UTGST, or IGST.
• Total Invoice Value: Final amount including GST.

GST Treatment for UIN Transactions

From the Seller's Perspective

You charge applicable GST rates, issue a proper tax invoice with the buyer's UIN, collect the full amount including GST, and report the transaction in GST returns like any other B2B supply.

From the UIN Holder's Perspective

The UIN holder pays the full invoice amount including GST and files a refund application with GST authorities.

UIN Refund Process

1. Collect invoices with GST paid.
2. File refund claim using Form GST RFD-10.
3. Submit invoices and statements.
4. GST department verifies the claim.
5. Refund credited to bank account.

Common Mistakes to Avoid

• Not showing UIN correctly.
• Treating UIN as tax-free supply.
• Incorrect UIN format.
• Missing HSN/SAC codes.
• Not reporting in GST returns.
• Issuing incorrect credit notes.
