How This Calculator Works
Calculation methodology and assumptions
Side hustle tax calculation for New Hampshire. Side income over $400 triggers self-employment tax (15.3% on 92.35% of net earnings), covering Social Security (12.4%) and Medicare (2.9%). Federal and state income tax apply at marginal rates based on combined W-2 + side income (side income is treated as stacking on top of day-job income, matching the actual marginal-bracket effect). New Hampshire has no state income tax. Deductible expenses reduce both income tax and SE tax bases.

Example Calculation
Let's calculate the real take-home from a side hustle alongside a full-time job.
A software engineer earning $90,000 W-2 salary starts a freelance design side hustle earning $25,000/year. Business expenses: $3,000 (software, equipment). Net SE income: $22,000. The side hustle income is taxed at the marginal rate (22-24% federal), plus SE tax (15.3% on 92.35% of net income), plus state income tax.
Result: Side hustle taxes: SE tax ($3,105) + federal income tax (~$5,280 at 24% marginal) + state tax (~$1,100-$2,200). Total taxes on $22,000 net: approximately $9,485-$10,585. Take-home from side hustle: $11,415-$12,515 (52-57% of net income). Contributing $5,000 to a SEP IRA would save ~$1,900 in taxes while building retirement savings.
