Indiana rules for freelancers
- State income tax (2026)
- Indiana has a flat 2.95% state income tax for 2026. The state rate is scheduled to drop to 2.90% in 2027. Every county also levies a local income tax. Under Departmental Notice #1 (effective Oct. 1, 2026), county rates run from 0.5% (Porter) to 3.0% (Randolph): https://www.in.gov/dor/files/dn01.pdf
- State estimated tax
- Generally required if you owe $1,000 or more in combined state and county income tax for the year that withholding doesn't cover. Same dates as federal (April 15, June 15, September 15, and January 15 of the next year). Form ES-40.
- Marketplace contractor law (IC 22-1-6-3)
- App-based marketplace contractors are treated as independent contractors under all state and local law if nearly all pay is based on services or output and a written contract says they are independent contractors. The contract must also let them set their own hours, work for others without restriction, and bear their own expenses.
- Workers' compensation exemption certificate (Form WCE-1)
- Independent contractors who aren't required to carry workers' compensation can get an exemption certificate through Indiana DOR. The application fee is $20, and all Indiana tax returns must be filed and any delinquencies paid.
Federal rules for 2026
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
All income counts, form or no form
Clients and marketplaces send 1099-NEC or 1099-K forms only above IRS reporting thresholds, but every dollar of freelance income is taxable whether or not a form arrives.
Home office and tools
If you use part of your home regularly and only for work, the simplified home-office deduction is $5 per square foot up to 300 square feet. Software, equipment and a business share of your phone and internet are deductible too.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

|---|---|
| Self-employment tax per quarter | $3,003 |
| Solo 401(k) maximum | $40,299 |
