Indiana Registered Retail Merchant Certificate: How to Register for Sales Tax

If you sell taxable goods at a retail location in Indiana, you need a Registered Retail Merchant Certificate (RRMC) before you collect sales tax from customers. The RRMC is the registration that lets you collect Indiana's 7% state sales tax and report it to the Indiana Department of Revenue (DOR). People search for it as an Indiana sales tax license, Indiana sales tax permit, Indiana sales tax registration, or Indiana seller's permit, but the state's name for it is the Registered Retail Merchant Certificate, often shortened to RRMC.

This guide covers who needs one, how to register through INBiz, what it costs, how sales tax filing works afterward, and where the rules are still unclear.

This article is general information, not legal or tax advice. Whether your sales are taxable and how the rules apply to your business should be confirmed with the Indiana Department of Revenue or a qualified CPA or attorney.

What the RRMC Is

The RRMC is issued by the Indiana Department of Revenue. It registers your business as a retail merchant so you can collect sales tax on taxable sales at each location. Indiana does not have one comprehensive business license. The state's Business Owner's Guide says so directly. For most retail sellers of taxable goods, the RRMC is the main registration the state requires, and it is the one you will use every time you file sales tax.

The RRMC does not cover profession-specific licenses, local permits, or zoning approval. Those come from other agencies, and they are covered in a later section.

Who Needs an RRMC

You need an RRMC in two common situations.

• Retail sellers with an Indiana location. You need one RRMC for each retail location. A business with three stores in Indiana needs three certificates, and each certificate carries its own fee.
• Out-of-state sellers with no Indiana location. You need an RRMC when your gross Indiana sales exceed $100,000 in the current or prior calendar year. The threshold comes from IC 6-2.5-2-1, as described on the Taxes and Fees page of INBiz.

Before you register, confirm that what you sell is taxable. The certificate obligates you to collect and remit tax on taxable sales, so registering for the wrong reason or misreading what is taxable creates problems later. If you buy inventory that you plan to resell, you will use a resale certificate with your suppliers. That is a separate document from the RRMC, and this guide does not cover it.

What to Gather Before You Start

Having the following information ready will keep the online session from stalling:

• Your legal business name, exactly as it appears on your formation documents or your sole proprietorship name.
• Your entity type, such as sole proprietorship, partnership, LLC, or corporation.
• Your federal Employer Identification Number (EIN) or the identifier the DOR requires for your entity type. Confirm which identifier applies to your situation before you start.
• The street address of every place of business where you sell taxable goods. The certificate is issued per location, so you need each address.
• The date you plan to start collecting sales tax.

If your business is an LLC or corporation, check that the entity is on file with the Indiana Secretary of State, Business Services Division. You can search at bsd.sos.in.gov/publicbusinesssearch. A name mismatch between your entity records and your tax registration causes avoidable delays and confusion.

How to Register Through INBiz

Indiana handles RRMC registration through INBiz, the state's online business portal. The registration form is the Business Tax Application, referred to as BT-1. Here is the process from start to finish:

1. Open INBiz. Go to inbiz.in.gov and create an account or sign in to an existing one.
2. Start a Business Tax Application (BT-1). Select the option for a Registered Retail Merchant Certificate. Do not choose a different tax type by mistake, because the sales tax account is created from this registration.
3. Enter your business information. Provide your legal name, entity type, identifiers, and contact details.
4. Add each place of business. Enter every retail location. Each one needs its own RRMC, so the fee applies per location.
5. Pay the fee. The INBiz fee calculator lists $25 per place of business. Review the total before you submit payment.
6. Save your confirmation and certificate. Keep the confirmation and the certificate in your records. Your sales tax account is created from this registration, and you will file through it in the next step.

Do not start collecting sales tax until you have the certificate in hand and have confirmed your account is active. Collecting tax without a valid registration puts you in a difficult position when it is time to remit.

What the Registration Costs

The table below lists the figures that matter for budgeting. Anything marked as a confirmation item should be checked with the Department of Revenue before you rely on it.

Item	Amount or Rule	Notes
RRMC fee	$25 per place of business	Per the INBiz fee calculator. One certificate per location.
State sales tax rate	7%	Collected on taxable sales and filed through INTIME.
Renewal	Automatic at no charge, per DOR guidance	Confirm the terms with DOR. See the renewal section below.
Reinstatement of an expired certificate	Through INtax Pay	Confirm the steps and amounts with DOR.

Filing and Paying Sales Tax in INTIME

Registration creates your INTIME account. This is where you file and pay sales tax. Once the account is active, sign in and confirm your filing schedule, your tax type, and your locations. The DOR assigns your filing frequency, so check it in the account instead of assuming a schedule. Set a calendar reminder for each due date from the first period.

Good records make filing straightforward. Keep a record of:

• Gross taxable sales for each location and each period.
• Sales tax collected from customers.
• Exempt sales, with the documentation that supports each exemption.
• Payment confirmations for every return.

Filing late or leaving a return unfiled creates a problem beyond the late tax itself. The renewal rules below depend on your returns being filed and your tax being paid.

Renewal and Reinstatement

Department of Revenue guidance indicates that the RRMC renews automatically at no charge as long as your business has filed its returns and has no unpaid sales, use, or withholding tax. If a certificate expires, it is reinstated through INtax Pay after your liabilities are paid or after you set up a payment plan.

Confirm this with the Department of Revenue before you rely on it. Ask about the renewal term, the no-charge condition, and the exact reinstatement steps. Rules and online processes change, and the DOR is the authority on your account. Start at in.gov/dor.

Local Permits, Health Departments, and Other Licenses

The RRMC is one piece of the paperwork. Depending on your business, you may also need:

• Profession-specific licenses from the Indiana Professional Licensing Agency, if your work requires one.
• Local permits and zoning approval from your city or county, which govern where you can operate and what you can build or change at a site.

Food businesses need extra care. Do not assume the RRMC is the document a local health department requires before it issues a food permit. We have not verified whether the Marion County health department requires an RRMC before issuing a food permit. Confirm the permit prerequisites directly with the local health department before you sign a lease or buy equipment.

Common Mistakes to Avoid

• Registering one certificate for several stores. Each place of business needs its own RRMC and its own $25 fee.
• Collecting tax before the certificate is in place. Start collecting only after your registration is active.
• Mismatched names. If the name on your tax registration does not match your entity records, fix it before it causes a problem with filing or renewal.
• Ignoring the out-of-state threshold. An out-of-state seller with no Indiana location still needs an RRMC once gross Indiana sales exceed $100,000 in the current or prior calendar year.
• Letting a return slide. An unfiled return or unpaid tax can affect renewal and reinstatement.

Frequently Asked Questions

Is the RRMC the same as a seller's permit or sales tax permit?

People use several names for the same kind of registration. In Indiana, the document the Department of Revenue issues to retail merchants is the Registered Retail Merchant Certificate. Search terms like seller's permit, sales tax permit, and sales tax license describe the same general need. Confirm the exact name and form on the DOR website before you register.

Do I need an RRMC if my business is online only?

It depends on whether you have an Indiana location. If you have a place of business in Indiana where you sell taxable goods, you need an RRMC for that location. If you are an out-of-state seller with no Indiana location, you need an RRMC once your gross Indiana sales exceed $100,000 in the current or prior calendar year. Because online sales raise specific questions, confirm your situation with the DOR or a qualified tax professional.

How much does a Registered Retail Merchant Certificate cost?

The INBiz fee calculator lists $25 per place of business. A business with two Indiana locations pays $25 for each location.

How long does registration take?

This guide does not state a processing time for the RRMC, because one has not been verified. Ask the Department of Revenue for the current timeline before you plan an opening date, and do not start collecting tax until your certificate and account are active.

Where can I get free help with the process?

The Indiana Small Business Development Center (Indiana SBDC) offers business advising at isbdc.org. An advisor can help you organize your registration questions before you talk to the DOR or a tax professional. SBDC advisors do not replace a CPA or attorney for legal or tax decisions.

Next Steps

For most retail businesses in Indiana, the path is straightforward: confirm that what you sell is taxable, gather your location and entity information, register through INBiz for $25 per location, and set up your INTIME filing before your first taxable sale. Then confirm your renewal terms and any local permit requirements with the agencies that govern them.

Start with the Department of Revenue's business registration page at the DOR business registration page. Use the INBiz portal at inbiz.in.gov to submit your application.
