Taxation

What Is the Current Sales Tax Rate in Indiana?

The state-level sales tax rate in Indiana is 7%. While some states authorize counties to impose local sales taxes, Indiana counties do not (as of February 2025). However, counties collect other taxes, such as County Innkeeper’s Tax (CIT), Food and Beverage Tax (FAB), and Local Income Tax (LIT).

Indiana Sales Tax and Use Tax

Sales tax is collected by the seller on sale of goods. In Indiana, the sales tax rate is 7%. However, at times, the seller may not collect sales tax from customers for certain reasons (ex: lack of sales tax nexus, exemptions). In those cases, the buyer of goods must pay use tax to the Indiana Department of Revenue, instead of the seller. The buyer must pay 7% of the purchase price of the product as use tax.

Let us take an example to understand use tax. Jane, a resident of Indiana, purchases a dress for $200 from an online store. The online store does not have a sales tax nexus in Indiana and does not collect sales tax from Jane. In this case, Jane owes a use tax of $14 (7% x $200) to Indiana DOR.

When Do Businesses Need To Collect Indiana Sales Tax?

Businesses are required to collect and remit sales tax when a sales tax nexus is established. This can occur through:

1. Physical nexus

If your business has a physical presence in Indiana, then a physical nexus is established. Read our complete guide on sales tax nexus to know when businesses are required to collect tax.

Physical presence can be defined as:

  • Maintaining offices, distribution centers, warehouses, etc. in Indiana. This can be on a permanent or temporary basis, directly by the seller or indirectly through a representative or agent.
  • Having a representative, salesman or agent who operates in Indiana with the authority or on behalf of the seller. Activities performed by these representatives include delivery, sales, installation, receiving orders, and repair services.

2. Economic nexus

Economic nexus applies when your business does not have a physical presence in Indiana.

Your business will have an economic nexus when you have a gross revenue exceeding $100,000 in the current or previous calendar year from:

  • Sale of tangible property that is delivered into Indiana, or
  • Product transferred electronically into Indiana, or
  • Service delivered in Indiana

Earlier, there was another threshold to determine economic nexus. Sellers had economic nexus when they made 200 or more separate transactions in Indiana in the current or previous calendar year. This threshold was removed by Indiana DOR in 2024.

Understand the latest sales tax thresholds and how they affect online sellers.

Consequences of Failing To Collect Sales Tax

Understanding why sales tax is important for businesses can help you avoid legal and financial penalties. Failing to collect and remit sales tax may result in:

  1. Monetary penalty of up to 20% and a minimum penalty of $5 for late filing of sales tax returns.
  2. Expiration of the seller’s Registered Retail Merchant Certificate (RRMC) when tax dues are not paid.

Sales Tax Obligations for Marketplace Facilitators

Marketplace facilitators are businesses that operate a marketplace and facilitate retail transactions between buyers and sellers. They can be either online (like Amazon) or physical.

In Indiana, marketplace facilitators must collect and remit sales tax on behalf of their sellers’ transactions into Indiana. A marketplace facilitator that has a physical or economic nexus in Indiana would be required to collect and remit sales tax even when the seller (for whom they facilitate transactions) does not collect sales tax.

Registration Requirements for Sales Tax in Indiana

To collect and remit sales tax in Indiana, sellers must hold a Registered Retail Merchant Certificate. There are two ways to register and obtain this certificate:

1. Registration With Indiana Department of Revenue

  • A seller can register with Indiana DOR to collect tax by filling out the Form BT-1 offline or online through their business registration portal, InBiz.
  • $25 non-refundable application fee must be paid.
  • After filling the form and paying the application fee, the retail merchant receives a tax identification number and Registered Retail Merchant Certificate (RRMC).
  • The certificate is valid for two years and updates automatically.
  • A separate application is required for each new business location.

2. Registration Under Streamlined Sales Tax Registration System (SSTRS) To collect sales tax, businesses must register. Learn how to obtain a sales tax permit for compliance.

  • The Streamlined Sales Tax Registration System (SSTRS) provides a simple way for a business to register for sales tax in full member states of the Streamlined Sales Tax group, which Indiana is a part of.
  • Businesses that register under SSTRS must collect and remit sales tax to all selected states even if they don’t have a nexus.
  • This choice is suitable for businesses that have multi-state operations.
  • You can check the official website for more details on SSTRS registration.

Collecting Sales Tax In Indiana

There are three steps involved in collecting sales tax. A retailer needs to collect sales tax only when there is a sales tax nexus (physical or economic) in the state of Indiana.

1. Determine Taxability of Items Sold

In Indiana, only sale of goods and tangible personal property is taxable. As a retailer, you must identify if the product you sell is taxable or not. We have provided a list of common exceptions later in this guide. You must also keep an eye on updates through the sales tax information bulletin of Indiana.

2. Calculate Sales Tax Amount

Once you know that your purchase is taxable, the next step is to figure out how much sales tax you’ll pay. In Indiana, the state sales tax rate is 7%.

Basic formulas:

  • Sales Tax Amount = Purchase Price × 0.07
  • Total Cost = Purchase Price + Sales Tax Amount

Example: Buying a Car in Indiana

Product: Sedan
Purchase Price: $30,000
Indiana Sales Tax Rate: 7% (0.07)

1. Calculate the sales tax:
Sales Tax = $30,000 × 0.07 = $2,100

2. Calculate the total cost:
Total Cost = $30,000 + $2,100 = $32,100

So, a $30,000 vehicle purchase in Indiana results in $2,100 in sales tax for a total cost of $32,100.

Tax-Exempt Entities

There are certain entities that are exempt from paying sales tax. These include:

1. Indiana State and Local Government Entities

Any purchase or sale by Indiana state and local government agencies are exempt from sales tax. That is unless they engage in commercial activity that does not directly serve the public welfare.

2. US Government Entities

Any purchase made by the United States government agencies is exempt from sales tax.

3. Non-Profit Organizations

Purchases made by non-profit organizations are exempt from sales tax, provided the product purchased is used for non-profit purposes and the buyer is a qualified non-profit organization. Purchases made by non-Indiana non-profit organizations may also be exempt from sales tax. Learn more about the taxability of purchases and sales by non-profit organizations in Indiana here.

As a seller, when making sales to tax-exempt entities, you must maintain valid exemption certificates for such transactions. These exemption certificates are required at the time of sales tax returns filing. To understand how exemption certificates work, read our guide on sales tax exemption certificates.

Filing Sales Tax Returns in Indiana

Understanding sales tax compliance best practices can help businesses avoid errors while filing returns. Once sales tax is collected, you must file sales tax returns and remit the sales tax collected to the Indiana Department of Revenue.

  • Sales Tax Return Forms

Forms to be filed for sales tax returns are ST-103, ST-103MP, and ST-103CAR.

  • Mode of Filing

There is a mandate for electronic filing of sales tax returns through Indiana’s e-service portal, INTIME.

  • Deadlines

The deadline for sales tax filing varies with the average monthly tax liability.

  1. Early filers: Businesses having average monthly tax liability greater than or equal to $1,000 for the prior fiscal year ending on June 30 of the previous calendar year. They have to file the monthly sales tax return of the previous month by the 20th day of the current month.
  2. Monthly filers: Businesses with an average monthly tax liability of $1,000 or less. They have to file the monthly sales tax return of the previous month by the 30th day of the current month.
  3. Annual filers: Returns must be filed on January 31 every year.
