A UIN or Unique Identification Number is a GST Exempt class under GST regime for specified person/organisations such as foreign diplomatic missions and embassies, who do not carry any outward transaction and thus are entitled to the refund of the tax paid on inward supplies.

Application for UIN

For a Person/ Organization seeking to apply for a UIN is required to file form GST REG-13, wherein the given person/organization is a part of at least one of the categories given below:

• A specialised agency of the United Nations Organization
• A Multilateral Financial Institution and Organization notified under the United Nations (Privileges and Immunities) Act, 1947,
• Consulate or Embassy of foreign countries
• Any other person or class of persons as notified by the Commissioner

Upon successful filling, a proper officer, if satisfied, shall assign a UIN for the organization and issue the certification for the same in form GST REG-06.

GST Returns

Every UIN holder is required to file form GSTR-11 by 28^th day of the following month in order to claim a refund of the taxes paid on his inward supplies.  Form GSTR 11 consists of auto-populated information, as updated by the supplier and thus, the UIN holder is not allowed to add or modify any details in GSTR-11.

However, it should be noted that the UIN holder is required to file his returns within 6 months from the last day of the quarter in which supply was received. For example, if the supply was purchased in the month of May 2019, for which the last day of the quarter is June 2019, the refund should be claimed before December 2019. If the UIN holder fails to claim his refund within 6 months deadline, the refund shall lapse.

Supply from Regular Taxpayer

A regular taxpayer registered under GST is assigned a GSTIN (Goods and Service Tax Identification Number) and is required to mention recipients GSTIN for every transaction in account books, invoices and GST returns. However, how can a regular taxpayer maintain the records while supplying goods to the UIN holder?

The regular taxpayer can upload invoices in a similar manner to that for a normal B2B sales, wherein the GSTIN shall be replaced by recipients 15 digit UIN number.
