Review the tax impact
The calculator shows how much of your side hustle income you actually keep after federal income tax, SE tax (15.3%), and state income tax. The "take-home rate" is typically 55-70% of gross side hustle income.
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.
What Affects Your Results
Marginal Tax Bracket
Side hustle income is taxed at your highest marginal rate (on top of W-2 income). If your W-2 salary puts you in the 24% bracket, every dollar of side hustle income is taxed at 24%+ from dollar one.
Self-Employment Tax
The 15.3% SE tax applies to all side hustle income regardless of your other employment. This is on top of income tax, making the combined tax rate 37-50% for many side hustlers.
Business Expenses
Legitimate deductions reduce your taxable income. The home office deduction, vehicle mileage, and equipment depreciation are the most commonly missed deductions for side hustlers.
State Income Tax
New Hampshire Side Hustle Tax's income tax applies to side hustle income at your marginal rate. In zero-income-tax states (TX, FL, WA, etc.), side hustle take-home is 5-13% higher than in high-tax states.
Platform Fees
Etsy, Uber, DoorDash, and other platforms charge 15-30% in fees/commissions. These are deductible but significantly reduce your gross-to-net calculation.
Tips for New Hampshire Side Hustle Tax Residents
- Set aside 30-40% of every side hustle payment for taxes. Open a separate savings account and auto-transfer immediately when you get paid — this prevents the quarterly estimated payment surprise.
- Deduct everything legitimate: supplies, software, a portion of home internet, phone (business use %), professional development, marketing costs. Every deduction saves 30-40¢ per dollar.
- File quarterly estimated taxes if you expect to owe $1,000+ in additional tax. Penalties apply for underpayment. If your W-2 covers 100% of prior year's tax liability, you can safely increase withholding instead.
- Track your effective hourly rate. If your side hustle earns $25/hr gross but takes $9/hr in taxes and $4/hr in expenses, you're netting $12/hr. Compare this to the value of your time.
- Some New Hampshire Side Hustle Tax require a business license or sales tax registration even for small side hustles. Check your local requirements — penalties for non-compliance often exceed the cost of compliance.
