Updated 15 days ago
In Indiana, the terms "Sales Tax Account Number" and "State Tax ID" are closely related, but they serve slightly different roles within the Indiana Department of Revenue (DOR) system.
Here is the breakdown of what each is, where to find them, and how they appear in the state portal.
1. State Tax ID vs Sales Tax Account Number
Term | What it is | Format |
State Tax ID or (Indiana Taxpayer ID (TID) | This is your 10-digit State Tax ID (TID), assigned by the state when you registered for your sales tax license. | 10-digit number (e.g., 0123456789) |
Sales Tax Account Number | Your specific sales tax account identifier consists of the 'RST-' prefix followed by a 10-digit number assigned to you by the state. The 10-digit number is not necessarily the same as TID. | RST-[10-digit number] (e.g., RST-0000000000) |
2. Where to Find the State Tax ID and Sales Tax Account Number
You can find the state tax ID (TID) in various ways.
1. Registered Retail Merchant Certificate (RRMC)
This is your "Seller's Permit." It is the most important document for your Indiana sales tax account. You will see the 10-digit TID and the 3-digit LOC prominently displayed here.
2. Welcome Letter / Registration Notice
When you first register via INBiz or the DOR, you receive a welcome letter that also shows the 10-digit TID.
