Income tax

New Hampshire state income tax (2026)

0%. New Hampshire is one of nine states without a personal income tax (the others: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming). Self-employed New Hampshire residents file a federal return (Form 1040 + Schedule C + Schedule SE) but no state income tax return is required for personal 1099 income.

Due dates

Quarterly payments — federal only for New Hampshire residents

Federal estimated tax due dates apply nationwide:

  • Q1 — April 15, 2026
  • Q2 — June 15, 2026
  • Q3 — September 15, 2026
  • Q4 — January 15, 2027

Pay through IRS Direct Pay (irs.gov/payments) for free bank transfers, or mail Form 1040-ES with a check.

Penalties

Safe harbor and underpayment penalty (federal only)

Because New Hampshire has no state income tax, you only need to worry about the IRS safe-harbor rule: pay either 90% of your current-year federal tax liability or 100% of last year's federal tax (110% if your prior-year AGI was over $150,000), spread across the four quarterly estimated tax due dates. Hit either threshold and you avoid the IRS underpayment penalty assessed on Form 2210.

For freelancers with rising income, paying 100% of last year's tax is usually the simpler play — you know the number with certainty in April. For those whose income is dropping or volatile, the 90%-of-current-year safe harbor protects you better but requires honest mid-year projections.

No state tax

What "no income tax" actually means in New Hampshire

New Hampshire's no-income-tax status simplifies New Hampshire-side filing for self-employed residents but doesn't eliminate tax obligations. Three details matter:

  • Federal still applies in full. Federal income tax brackets, the 15.3% SE tax, the Additional Medicare Tax (0.9% above $200k single / $250k MFJ), and the federal QBI deduction all apply identically to New Hampshire residents.
  • Sales tax + property tax fill the gap. States without income tax typically have higher-than-average sales and/or property taxes. New Hampshire is no exception. Plan accordingly when budgeting total tax burden — your federal-and-SE bill is only part of the picture.
  • Multi-state work creates complexity. If you live in New Hampshire but perform work physically in a state with income tax, you may owe tax to that state on the income earned there. Common scenarios: traveling consultants, remote employees of out-of-state companies, multi-state contractors.
New Hampshire-specific quirk

New Hampshire-specific quirk freelancers miss

New Hampshire has no tax on wages, salary, or 1099 self-employment income. The state did historically tax interest and dividends (the I&D Tax) at 5%, but this was repealed effective 2025. NH freelancers now have a true 0% state return on all income types.

Common federal filing

Common federal filing mistakes New Hampshire freelancers make

Even without a state return, New Hampshire self-employed taxpayers consistently make four federal mistakes that cost money or trigger penalties:

  • Forgetting the 15.3% self-employment tax. SE tax is the freelancer's version of FICA — 12.4% Social Security + 2.9% Medicare, applied to 92.35% of net SE earnings. It's separate from federal income tax. Many first-year freelancers budget only for income tax bracket and get hit with an unexpected SE-tax bill.
  • Not separating business and personal finances. Without a separate business bank account, year-end reconciliation becomes a nightmare and audit risk rises. Even sole proprietors benefit from a dedicated checking account.
  • Skipping quarterly estimates entirely. If you owe more than $1,000 in federal tax at year-end and didn't pay quarterly, the IRS assesses an underpayment penalty. Even one quarter of estimates protects you against full-year penalty exposure.
  • Mixing gross receipts with net income. "I made $80,000 this year" usually means gross receipts. Your taxable SE income is gross minus business expenses (Schedule C line 31), and only THAT number is taxed. Track expenses ruthlessly.
Deductions

Common federal deductions for New Hampshire freelancers

Without a state return, your only itemization layer is federal. The deductions that matter most:

  • Standard business expenses — software, contractors, supplies, professional services.
  • Home office — simplified ($5/sq ft up to 300 sq ft) or actual percentage of rent/utilities.
  • Mileage — $0.70/mile in 2026 (business use).
  • Half of SE tax — federal above-the-line deduction.
  • QBI deduction — 20% of qualified business income, federal.
  • SEP-IRA / Solo 401(k) — major shelter for high-income freelancers.
  • Self-employed health insurance premiums — fully deductible if no W-2 spouse coverage.
