Marketplace seller taxes in New Hampshire
Etsy, eBay, Shopify and the rest report your gross and withhold nothing. The gap between that and what you are taxed on is your costs, in New Hampshire that gap is worth $5,937 in tax.

Earning more in New Hampshire
A single filer taking the standard deduction, this work as the only income, the calculator above handles the other filing statuses. Miles rise with earnings, so the deduction rises too, and the effective rate on gross climbs more slowly than it would for someone whose income grew without expenses attached:
| Volume | Gross | Mileage off | Taxable profit | New Hampshire tax | Total tax | Rate on gross |
|---|---|---|---|---|---|---|
| Part-time | $15,000 | $0 | $15,000 | $0 | $2,119 | 14.1% |
| Steady side income | $45,000 | $0 | $45,000 | $0 | $8,579 | 19.1% |
| Full-time | $72,000 | $0 | $72,000 | $0 | $14,803 | 20.6% |
New Hampshire specifics that change the number
On the 2026 rate itself: dividend/interest tax fully eliminated effective Jan 1, 2025.
New Hampshire is also one of five states with no general sales tax, so the total tax picture is lighter than the income tax line alone suggests.
New Hampshire stopped taxing interest and dividends for periods after December 31, 2024, so wages, self-employment profit, and investment income are all now state-tax-free for individuals. Businesses are another matter: the Business Profits Tax runs 7.5%, and the Business Enterprise Tax takes 0.55% of compensation, interest, and dividends paid once gross receipts pass $298,000 (for periods beginning on or after January 1, 2025). Below that threshold a small operation files nothing.
Selling into and out of New Hampshire
Income tax follows you: New Hampshire taxes your profit wherever the buyer was. Sales tax does not. Marketplace facilitator laws make the platform collect and remit sales tax on your behalf in most states, which is why a seller can have customers in all fifty and still file only one income tax return. Selling off-platform is where that stops being true.
On $18,225 of profit, what the states around New Hampshire would charge:

|---|---|---|
| Vermont | $611 | +$611 |
| Massachusetts | $911 | +$911 |
| Maine | $1,057 | +$1,057 |
- Vermont would take $611 more, $611 against New Hampshire's $0.
- Massachusetts would take $911 more, $911 against New Hampshire's $0.
- Maine would take $1,057 more, $1,057 against New Hampshire's $0.
Marketplace seller tax questions in New Hampshire
How much should a New Hampshire seller set aside?
About 5.9% of gross on the $45,000 example, $2,642 across self-employment tax, federal income tax and nothing to New Hampshire. In practice that means moving about $59 of every $1,000 payout into a separate account the day it lands, and sending roughly $661 to the IRS each quarter, no platform withholds any of this for you. Set aside from each payout rather than finding it in April.
Does the $45,000 on my 1099-NEC match what New Hampshire taxes?
No. New Hampshire taxes profit, not gross. After $26,775 of deductions the taxable figure is $18,225, so there is no New Hampshire tax either way. But the federal side drops by $5,937. The form reports what the platform paid out, it knows nothing about your costs, and no one subtracts them for you. On this example 60% of the gross never becomes taxable income, but only for the seller who kept the records to prove it.
