Seller’s Permit Requirements in New Mexico: Registration Basics (Indiana Context)
What a Seller’s Permit Means for Indiana Businesses
In Indiana, a “seller’s permit” is commonly used to describe the state registration that allows a business to collect Indiana sales tax and issue resale certificates when buying inventory for resale. Indiana administers sales tax through the Indiana Department of Revenue (DOR). If you make taxable retail sales, rent/lease taxable items, or sell taxable services in Indiana, you generally need to register before you begin collecting tax.
Common names you may hear
- Registered Retail Merchant Certificate (RRMC)
- Sales tax permit / sales tax registration
- Seller’s permit (informal term)
Do You Need to Register? Practical Triggers
You should plan to register for Indiana sales tax when you do any of the following:
- Sell tangible personal property to Indiana customers (in-store, delivered, or shipped into Indiana).
- Sell at events, pop-ups, markets, or trade shows in Indiana.
- Maintain a physical presence in Indiana (office, warehouse, employees, inventory, or regular in-person selling).
- Make remote sales into Indiana that create an obligation to collect Indiana sales tax under Indiana’s remote seller rules.
- Buy inventory or materials for resale and need to provide a resale certificate to suppliers.

Marketplace sales
If you sell through a marketplace, the marketplace may collect and remit tax on certain transactions. Even so, you may still need a permit depending on your overall business activities and whether you also sell directly to customers.

FAQ: Seller’s Permit Requirements in Indiana (IN)
1) Is a “seller’s permit” the same thing as an Indiana sales tax permit?
Yes. In Indiana, “seller’s permit” is a common informal term for sales tax registration, often evidenced by a Registered Retail Merchant Certificate (RRMC) or similar authorization to collect sales tax.
2) When should I register—before or after my first sale?
Register before making taxable sales and before collecting Indiana sales tax. This helps ensure you are authorized to collect tax and can file correctly from day one.
3) Do I need a seller’s permit if I only sell online to Indiana customers?
Possibly. If your online sales into Indiana create a sales tax obligation under remote seller rules, you should register and begin collecting and remitting Indiana sales tax.
4) Do I need a permit if I sell only wholesale (resale) and not to the public?
Many wholesalers still register because they may need to issue resale certificates and may have taxable transactions (such as selling to non-exempt buyers). Your exact need depends on your activities and whether you make taxable retail sales.
5) Can I use my Indiana seller’s permit to buy inventory tax-free?
You can generally buy items intended for resale without paying sales tax by providing a proper resale certificate to your supplier. Purchases for business use (equipment, supplies) are typically taxable.
6) What if I operate from home in Indiana?
Home-based businesses making taxable sales generally still need to register. Your home address may be used as the business location, and you must comply with collection and filing requirements.
7) Do I need a separate seller’s permit for each Indiana location?
Indiana registration and location reporting can vary based on how your account is structured and where sales occur. If you add locations, update your registration to reflect each place of business as required.
8) What records should I keep after I get my permit?
Keep sales invoices, exemption and resale certificates, shipping/delivery documentation, marketplace reports, and your filed returns and payment confirmations. Good records support correct tax treatment and audit readiness.
9) If I sell at craft fairs or weekend markets, do I need to register?
Yes in most cases where you make taxable retail sales in Indiana. Event selling is a common trigger for registration and sales tax collection responsibilities.
10) What happens if I collect sales tax without being registered?
Collecting tax without proper registration can create compliance issues, including difficulty filing correctly and potential penalties. Register first, then collect and remit under your account.
