An operating brief for one move — not an explainer. It reads the reasoning graph from origin to destination and returns what the household must coordinate: the priorities that change, the standing decisions the move makes stale, and the actions to take before, during, and after the crossing.
Relocating from Massachusetts to New Hampshire materially reduces the household's state estate-tax exposure, with the household's coordination priorities largely carrying over.
Only the dimensions the move actually changes — origin on the left, destination on the right.
| What changed | In Massachusetts | In New Hampshire | |
|---|---|---|---|
| Capital-gains rate | 9%Loss treatment conforms to federal: capital losses net against gains and carry forward. Top effective long-term rate 9%. Quirk: 5% long-term + a 4% surtax over ~$1.1M; short-term 8.5% likewise + the 4% surtax. | → | 0%No state tax on capital gains — and a harvested loss is worth only the federal rate here. |
| Estate & inheritance | estateState estate tax (paid by the estate): top rate ~16%, exemption ~$2M. $2M exemption with a uniform $99,600 credit; the 2023 reform removed the old cliff, so only value above $2M is taxed. | → | No state estate or inheritance tax — only the federal estate tax applies. |
| Marriage treatment | flatA single flat rate regardless of filing status — marriage-neutral on rate; watch fixed-dollar exemptions and AGI thresholds. | → | No state income tax — no marriage penalty on the state return. |
| Loss treatment | federalCapital losses carry forward under the federal Section 1212 rules — a harvested loss nets against gains and rolls forward until used. | → | No state tax on capital gains, so a harvested loss carries no state benefit; its value here is only the federal offset. |
| Municipal bonds | in-stateOnly in-state municipal-bond interest escapes state tax; bonds from other states are taxed. The classic in-state muni preference that rewards a home-state ladder. | → | exemptMunicipal-bond interest is exempt from state tax whether the issuer is in-state or out-of-state — the broadest muni preference (states with no tax on investment income, plus a few that exempt all munis by statute). |
| QSBS (§1202) | §1202 okConforms to IRC §1202 — the federal qualified small business stock gain exclusion carries through to the state return. | → | no §1202No distinct state QSBS position applies here — either the jurisdiction levies no tax on the gain, or it does not separately recognize the §1202 exclusion. Confirm with a tax advisor. |
What the household coordinates in the new environment — who owns it, how soon, and what it depends on. New marks a priority the move opens.
No standing coordination priorities are triggered at the destination — the environment is simple.
Decisions calibrated to the origin's environment that the move makes stale — worth revisiting, not assuming.
No state tax on gains — every realized gain keeps its full federal-only outcome.
No state estate or inheritance tax — only the federal estate tax reaches the estate.
With no state tax on gains, a harvested loss recovers only its federal value — the state adds no rate for it to offset.
Already a no-income-tax, no-estate-tax state — the destination other households move toward, not from.
no longer triggered at the destination — one fewer thing to coordinate.
