Capital Gains Tax in New Hampshire: No State Tax, But Federal Applies

New Hampshire has no state income tax — so no state capital gains tax. But the federal rate (up to 20%) and the 3.8% NIIT still apply. Here's how to defer the federal bite.

New Hampshire has no state income tax — and therefore no state capital gains tax. New Hampshire has no tax on capital gains (its tax on interest and dividends is being phased out). But the federal capital gains rate (up to 20%) and the 3.8% Net Investment Income Tax still apply, and on a large business, property, or stock sale that federal bite alone can run to roughly a quarter of your gain in a single year.

Where the tax still bites

No state tax is a real advantage — but recognizing the entire federal gain in one year still maxes out the 20% bracket and triggers the 3.8% surtax. For retirees, a one-year gain can also spike Medicare IRMAA premiums two years later.

The structured installment sale solution

A §453 structured installment sale spreads the proceeds — and the federal gain — across future years, keeping more in the 15% bracket, reducing the 3.8% NIIT, and (for retirees) helping avoid the IRMAA cliff. Payments are carrier-backed and guaranteed; no replacement property required.

Why New Hampshire sellers still use it:
  • No state tax doesn't change the federal 20% + 3.8% on a big one-year gain.
  • Spreading can keep much of the gain at 15% and dodge the surtax.
  • Doubles as guaranteed retirement income from the sale.

The takeaway

New Hampshire saves the state tax, but the federal tax on a large sale is still the biggest check most people write. Estimate it on the calculator and plan before you close.

Frequently asked questions

Does New Hampshire have a capital gains tax?

No. New Hampshire has no state income tax, so there is no state capital gains tax. You still owe federal capital gains tax (up to 20%) and the 3.8% Net Investment Income Tax.

How much capital gains tax will I pay on a sale in New Hampshire?

No state tax, but federally up to 20% plus the 3.8% NIIT — roughly a quarter of a large gain in the year of sale, with depreciation recapture on top for property.

Can I defer federal capital gains tax in New Hampshire?

Yes. A §453 structured installment sale spreads the federal gain over several years, keeping more in the 15% bracket and reducing the 3.8% surtax. The lack of state tax doesn't affect this federal strategy.

Is a structured installment sale worth it with no state tax?

Often yes — the federal 20% rate plus the 3.8% NIIT on a large one-year gain is still substantial, and spreading can meaningfully lower it while providing guaranteed income.
