What's different in Indianapolis
- Local income tax
- Marion County Local Income Tax (Indiana county income tax): 0.0202% for residents (effective Rate shown in Indiana DOR Departmental Notice #1, effective Oct. 1, 2026). If you lived in Marion County on Jan. 1, the 2.02% county tax is figured on Schedule CT-40 from your Indiana adjusted gross income, which starts from federal AGI and so includes net self-employment and 1099 profit. If you owe $1,000 or more in combined state and county tax not covered by withholding, you generally must make quarterly estimated payments.
- Indiana business personal property tax (Marion County)
- Business equipment is assessed each Jan. 1, with returns due May 15 (May 15, 2026 this year). Starting with the 2026 assessment date, a business whose total personal property acquisition cost in the county is under $2,000,000 is exempt, but must claim the exemption on Form 102 or 103 (plus Form 104) unless it already claimed it in an earlier year and still qualifies.
- Also worth knowing
- County is set by residence on Jan. 1. People who live outside Indiana but whose principal place of work or business is in Marion County on Jan. 1 pay Marion County's rate; Indiana residents of other counties pay their home county's rate (https://www.in.gov/dor/files/dn01.pdf). Return mechanics (federal AGI start, Schedule CT-40): https://www.in.gov/dor/i-am-a/individual/first-time-filer/your-indiana-tax-return-line-by-line. Estimated payment rule ($1,000 or more in state and county tax not covered by withholding; due April 15, June 15, Sept. 15, Jan. 15): https://www.in.gov/dor/i-need-to/make-a-payment/estimated-payments. Indiana DOR says all existing local income tax rates will expire and must be readopted during the 2027 budget process, and starting in 2028 cities and towns of 3,500+ people may impose their own local income tax of up to 1.2% (https://www.in.gov/dor/files/tax-chapter.pdf). No local gig-worker pay ordinances were found.

- State estimated tax

- Marketplace contractor law (IC 22-1-6-3)

Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
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.
A worked example
| Self-employment tax | $9,891 |
|---|---|
| Self-employment tax per quarter | $2,473 |
| SEP IRA maximum | $13,011 |
| Solo 401(k) maximum | $37,511 |
