Working for yourself in Indiana offers flexibility, independence, and control over your income. But it also means you are fully responsible for managing and paying your own taxes. Whether you are a freelancer, independent contractor, gig worker, consultant, or small business owner, understanding Indiana self-employed taxes for 2025–2026 is essential to avoid penalties and keep more of what you earn.

Unlike W-2 employees, self-employed individuals do not have taxes withheld automatically. You must calculate federal self-employment taxes, pay Indiana state income tax, make estimated quarterly payments, track deductions, and stay compliant with sales tax rules if applicable.

This guide explains everything in step by step, so you can confidently handle your Indiana self-employed tax obligations without confusion.

Who Is Considered Self-Employed in Indiana?

You are considered self-employed in Indiana if you earn income outside of traditional employment and receive payments without tax withholding. This includes:

• Freelancers and independent contractors (1099 workers)
• Gig workers (rideshare drivers, delivery drivers, task-based work)
• Sole proprietors and single-member LLC owners
• Consultants, designers, writers, developers, and marketers
• Side hustlers earning additional income outside a regular job

If you earn $400 or more in net self-employment income, you are required to file a federal tax return and pay self-employment tax.

Understanding Self-Employment Taxes in Indiana

Self-employed taxes include federal taxes and Indiana state taxes. These are calculated separately but paid throughout the year using estimated payments.

Federal Self-Employment Tax Explained

Federal self-employment tax covers your contributions to Social Security and Medicare. When you work for yourself, you pay both the employee and employer portions.

For 2025–2026, the rates are:

• Social Security tax: 12.4% (on net income up to the annual limit)
• Medicare tax: 2.9% (on all net income)
• Additional Medicare tax: 0.9% if income exceeds:
  • $200,000 (single filers)
  • $250,000 (married filing jointly)

The total standard self-employment tax rate is 15.3%.

The good news is that you can deduct half of your self-employment tax when calculating your adjusted gross income, which lowers your overall federal tax bill.

Indiana State Income Tax for Self-Employed Individuals

Indiana uses a flat state income tax, which makes calculations simpler than in many other states.

For 2025–2026:

• Indiana state income tax rate: 3.15%

In addition to the state rate, many counties impose a local county income tax, typically ranging from 1% to 3%, depending on where you live or operate your business.

Your total Indiana tax liability is calculated using:

• State income tax
• County income tax (based on your county of residence as of January 1)

Do Self-Employed Workers in Indiana Need to Pay Quarterly Estimated Taxes?

Yes. If you expect to owe $1,000 or more in total taxes for the year, you are required to make estimated quarterly payments to both the IRS and the Indiana Department of Revenue.

Quarterly Tax Payment Deadlines

Estimated tax payments are due on:

• April 15
• June 15
• September 15
• January 15 (of the following year)

Missing these deadlines can result in penalties and interest, even if you pay your taxes in full later.

How to Calculate Estimated Tax Payments

Calculating estimated tax payments is an important responsibility for self-employed individuals because taxes are not automatically withheld from your income. These payments cover both federal and state taxes and are usually made quarterly. Breaking the process into clear steps makes it much easier to manage.

Estimate Your Total Annual Business Income

Begin by estimating how much income your business will earn during the year before expenses. This includes all money you receive from freelance work, contracts, side gigs, or business sales. If your income changes from month to month, use what you’ve earned so far and make a reasonable projection for the rest of the year based on current work and contracts.

Subtract Deductible Business Expenses

Next, subtract your deductible business expenses from your total income. Common expenses include office supplies, software subscriptions, advertising costs, business travel, phone and internet used for work, home office expenses, and vehicle mileage. After subtracting these costs, you’ll arrive at your net self-employment income, which is the amount used to calculate most taxes.

Calculate Federal Self-Employment Tax

Federal self-employment tax covers Social Security and Medicare. This tax is generally calculated at 15.3% of your net self-employment income. Even if you don’t owe federal income tax, you may still owe self-employment tax, which is why it’s important to include this step in your calculation.

Estimate Federal Income Tax

After accounting for deductions, estimate your federal income tax based on your filing status and income level. Many self-employed individuals use their prior year’s tax return as a reference point. If your income is expected to be higher or lower this year, adjust the estimate accordingly.

Add Indiana State and County Income Taxes

Indiana charges a flat state income tax, and most counties also impose a county income tax. Your estimated payments should include both. County taxes depend on where you live or where your business is based, and they are commonly missed when estimating taxes, leading to underpayment.

Determine Your Total Annual Tax Liability

Once you’ve added together federal self-employment tax, federal income tax, and Indiana state and county taxes, you’ll have an estimate of your total annual tax obligation. This number represents what you should aim to pay throughout the year to avoid surprises at tax time.

Divide Taxes Into Quarterly Payments

Take your total estimated annual tax amount and divide it into four payments. These payments are typically due in April, June, September, and January of the following year. If your income changes during the year, you can recalculate and adjust future payments rather than waiting until tax season.

Use Last Year’s Return as a Starting Point

Using your prior year’s tax return as a baseline is a common and practical approach, especially if your income is fairly consistent. If your business grows or slows down significantly, reviewing and updating your estimated payments midyear can help prevent penalties and large tax bills.

Maintaining accurate records and reviewing your income regularly makes estimated tax payments far less stressful and keeps you in control of your tax obligations year-round.
