Indiana Business Tax Obligations for 2026

Taxes are one of the parts of running a business that owners most want to get right and most dread sorting out. If you run a small or blue-collar business in Indiana, the good news is that the basic picture is more manageable than it looks: your obligations mostly fall into a few clear categories, and once you know what they are, you can build them into your routine.

This overview walks through the main business taxes an Indiana business may owe in 2026 — state income and entity taxes, sales and use tax, and employer taxes — plus the dates to watch and where the line falls between what a business attorney handles and what belongs with your accountant. Two important notes up front: this is general information, not tax advice, and tax rates and thresholds change, so verify the current figures for your situation before relying on any number.

Overview of Indiana Business Taxes

Most Indiana small businesses deal with some combination of four things: income or entity taxes on the business’s earnings, sales and use tax if you sell taxable goods, employer taxes once you have employees, and certain county or local taxes.

Which apply to you depends on your structure, what you sell, and whether you have a payroll. Your entity type also affects how you are taxed, which is one reason it helps to line up your formation, payroll, and tax registrations together.

State Income and Entity Taxes

Indiana imposes state taxes on business income, and how that works depends on your entity. Many small businesses are pass-through entities — such as sole proprietorships, partnerships, and most LLCs — where the business’s income passes through to the owners’ personal returns. Corporations are taxed differently at the entity level.

Because rates and rules change and depend on your structure, confirm the current specifics with the Indiana Department of Revenue or a tax professional rather than relying on a figure you saw last year.

Sales and Use Tax Basics

If your business sells taxable goods in Indiana, you generally need to register with the Indiana Department of Revenue, collect sales tax from customers, and remit it to the state on a schedule. Use tax can apply to taxable items you buy without paying sales tax.

Whether and how these apply depends on what you sell and how, so services and product businesses can face different rules. Registering correctly and remitting on time keeps you clear of avoidable penalties.

Employer Taxes: Withholding and Unemployment

Once you hire employees, a new layer of tax obligations kicks in. You will generally withhold state and federal income tax and payroll taxes from wages and remit them, and you will handle unemployment tax through the Indiana Department of Workforce Development.

Getting your workers classified correctly matters here, because misclassifying an employee as a contractor can create back taxes and penalties — our guide on independent contractor vs. employee in Indiana covers how to get that right.

2026 Dates and What to Watch

Tax deadlines are easy to miss when you are busy running the work. Build a simple calendar for your filing and payment dates — sales tax remittances, payroll deposits, and annual returns — and watch for any changes to rates or thresholds that take effect in 2026.

Because these dates and figures can shift, confirm the current schedule for your business each year rather than assuming last year’s calendar still applies.

What Is Beyond Our Scope?

We help business owners understand their tax obligations at a basics level and coordinate them with formation and compliance. Complex tax planning, detailed return preparation, and specialized tax strategy are the domain of a CPA or tax professional, and we will gladly work alongside yours.

Think of it as a division of labor: your accountant runs the numbers, and we make sure your legal structure and obligations line up with them.

When to Get Help

It is worth a conversation when you are choosing or changing your entity, which affects your taxes, when you are about to hire your first employee, when you are unsure whether you owe sales tax, or when a classification question comes up.

At BOC, we regularly help Indiana business owners with entity formation, operating and partnership agreements, contracts and disputes, non-competes and NDAs, general Indiana compliance, business-tax basics, and worker classification.

A few matters are highly specialized and outside our usual scope, so we would point you to the right professional: complex data-privacy engineering beyond the basics of Indiana’s Consumer Data Protection Act, healthcare regulatory work, complex EEOC and employment litigation, and EPA matters.
