What will a 1099 year cost you?
Enter your expected net profit and a few rates. The estimator shows self-employment tax, federal, Indiana state and county tax, and the rough quarterly payment, so the number is not a surprise in April.
Your year
Use your marginal bracket after the standard deduction and other household income; most solo trainers land between 10 and 22 percent.
Indiana's flat rate has been stepping down each year; confirm the current year's rate on the Department of Revenue site.
Hamilton County residents pay a county rate on top of state tax; look up the current figure on the Department of Revenue county rate table.

General information, not tax advice. Checked September 2026. The estimator ignores credits, retirement contributions, health insurance deductions and the qualified business income deduction, all of which usually lower the real bill.
How the estimate is built
Self-employment tax is 15.3 percent applied to 92.35 percent of net profit, and half of it is deductible before income tax. Federal tax is your bracket applied to profit after that deduction. Indiana applies its flat state rate and your county's local rate to roughly the same base. Quarterly is the annual total divided by four.
| Line | Formula the tool uses |
|---|---|
| Self-employment tax | Profit times 0.9235 times 0.153 |
| Adjusted profit | Profit minus half of the self-employment tax |
| Federal income tax | Adjusted profit times your bracket estimate |
| Indiana state tax | Adjusted profit times the state rate |
| County tax | Adjusted profit times your county rate |
A worked example
$60,000 of net profit: self-employment tax is about $8,480. Adjusted profit is about $55,760. At a 12 percent federal bracket that is about $6,690; Indiana state at 2.95 percent is about $1,645; a county rate of 1 percent would add about $560. Total near $17,400, or roughly $4,350 a quarter, before any credits or retirement contributions bring it down.
Questions people ask
Before you trust the number
Is this tax advice?
No. It is an educational estimate that shows the shape of what a self-employed trainer owes. Rates change, deductions vary, and a CPA who knows Indiana small business will find things this page cannot.
What is the county tax line?
Indiana counties levy a local income tax on residents on top of the state rate. Rates vary by county and change over time, so enter the current rate for your county from the Department of Revenue table.
Do I really have to pay quarterly?
Generally yes once you expect to owe more than a small amount for the year. Federal and Indiana estimated payments are due four times a year, and the estimator divides the annual total by four to show the rough size.
