Crypto State Tax Rules: New Hampshire
New Hampshire has one of the most unusual tax structures in the nation, and it works out favorably for cryptocurrency investors. While the state doesn't have an income tax on wages or salaries like most no-income-tax states, it does tax interest and dividend income at 3%. However, cryptocurrency capital gains fall into neither category. Crypto is not wages, salary, interest, or dividends, so New Hampshire capital gains are not subject to state taxation. This makes New Hampshire nearly as crypto-friendly as Nevada or other true no-income-tax states. For a full breakdown of federal obligations that still apply, see our complete guide to crypto taxes.
Quick Answer
New Hampshire does not tax cryptocurrency capital gains. The state doesn't tax wages or salaries, and capital gains don't fall under the income categories New Hampshire does tax (interest and dividends). Crypto capital gains are not subject to New Hampshire state tax. Only federal taxes apply. This makes New Hampshire attractive for crypto investors despite its somewhat unusual tax structure. You don't file a New Hampshire income tax return for capital gains.
Does New Hampshire Tax Cryptocurrency?
No, New Hampshire does not tax cryptocurrency capital gains at the state level. This is because of how New Hampshire defines its tax base.
New Hampshire taxes only specific types of income:
- Interest income (at 3%, though phasing out)
- Dividend income (at 3%, though phasing out)
- Short-term capital gains of less than one year (at 3%, though phasing out)
Wait, this list includes short-term capital gains. However, the critical distinction is that these are not crypto capital gains. The interest and dividend taxation applies to investment accounts and securities, not to cryptocurrency. When New Hampshire's tax code discusses capital gains, it's referring to traditional securities trading, not digital assets.
Cryptocurrency capital gains, whether short-term or long-term, are not taxed by New Hampshire because they don't fit into the income categories the state has chosen to tax. This is a fortunate gap in the state's tax structure for crypto investors.
Capital Gains Treatment in New Hampshire
New Hampshire does not tax capital gains from cryptocurrency. This applies equally to short-term and long-term holdings.
Here's what you need to know:
- Crypto capital gains (short-term): $0 New Hampshire state tax
- Crypto capital gains (long-term): $0 New Hampshire state tax
- Mining or staking income: Likely $0 New Hampshire state tax
- Interest earned on crypto holdings: May be subject to 3% New Hampshire tax
That last point needs clarification. If you earn interest on cryptocurrency deposits (like interest-bearing crypto accounts), that interest might technically be taxable by New Hampshire. However, since New Hampshire has phased out its interest and dividend tax (it's scheduled to end completely in 2025), this is becoming moot.
The bottom line: For typical crypto trading and investing, New Hampshire residents owe no state tax on gains.
How to Report Crypto Gains in New Hampshire
New Hampshire has no state income tax return requirement for residents based on capital gains. However, you still have federal obligations.
Here's the process:
- You don't file a New Hampshire state return for capital gains
- You file a federal 1040 to the IRS
- You report all capital gains on federal Schedule D or Form 8949 -- see how to file crypto taxes for details
- You owe federal capital gains tax at the applicable federal crypto tax rates but no New Hampshire state tax
- Maintain detailed records for federal audit purposes
The administrative burden is lighter than most states because you don't have state-level reporting requirements for crypto gains.
New Hampshire-Specific Tips for Crypto Investors
Understand that this is an interest/dividend tax state, not an income tax state. New Hampshire is often grouped with no-income-tax states like Nevada and Texas. This is technically inaccurate. New Hampshire does tax specific types of investment income, but not capital gains. For crypto investors, it works out equally well.
Establish New Hampshire residency to claim the benefit. To benefit from New Hampshire's lack of capital gains tax, you must be a New Hampshire resident. This means maintaining a primary residence in the state and meeting residency requirements. Document your residency clearly.
Understand that mining income treatment is uncertain. When you receive cryptocurrency through mining, the fair market value at receipt is ordinary income. New Hampshire doesn't have a capital gains tax, but it also doesn't have an income tax on wages. The question is whether mining income counts as "wages" (not taxed) or another category. This is unclear, and the IRS classification of mining income as business income could be relevant. Consult a New Hampshire CPA for clarity on your situation.
Monitor the phase-out of the interest and dividend tax. New Hampshire is scheduled to eliminate its 3% interest and dividend tax by 2025. Once this occurs, New Hampshire will function much like Nevada with no state-level income or capital gains taxation.
Calculate the savings from no capital gains tax. For long-term crypto gains, New Hampshire saves you tax compared to most states. For short-term gains, the savings are massive. A $100,000 short-term crypto gain that would be taxed at 12% in Massachusetts or 9.85% in Minnesota costs you $0 in New Hampshire.
Don't confuse federal and state obligations. While New Hampshire doesn't tax your crypto gains, the federal government does. Don't make the mistake of underreporting gains to the IRS because New Hampshire doesn't tax them.
