New Hampshire has no bright-line day-count residency test. Here is what actually controls, and what a day count does and does not prove.
New Hampshire's actual test
New Hampshire has no day-count statutory residency test for income tax purposes, because it has no individual income tax to trigger one. 'Resident or inhabitant' is instead defined for general legal purposes (voting, jury duty, in-state tuition, and similar) under RSA 21:6 and RSA 21:6-a: a person domiciled or having a place of abode in New Hampshire whose actions demonstrate a current intent to make that place their principal place of physical presence to the exclusion of all others.
Domicile controls instead
Under RSA 21:6-a, 'residence or residency shall mean a person's place of abode or domicile... designated by a person as his or her principal place of physical presence to the exclusion of all others,' and that status 'shall not be interrupted or lost by a temporary absence... if there is an intent to return.' RSA 21:6 adds that the person must have, 'through all of his or her actions, demonstrated a current intent' to treat that place of abode as their principal residence, an actions-based test rather than a pure declaration of intent.

This jurisdiction does not run a bright-line day-count residency test. Domicile, the place you treat as your true, fixed, permanent home, controls instead, regardless of how many days you spend here.

New Hampshire Day-Count FAQ
How can I prove I actually live in New Hampshire and not just claim it on paper?+
Because New Hampshire has no income tax audit process to satisfy, the proof that matters is whatever your former high-tax state (commonly Massachusetts) demands to disprove its own residency claim: a New Hampshire driver's license and vehicle registration, voter registration under RSA 21:6-a's domicile standard, a day-count log showing more time in New Hampshire than the old state, and evidence the New Hampshire home is your actual principal place of physical presence.
How long do I have to get a New Hampshire driver's license and register my car after moving here?+
You have 60 days from establishing residency to do both, under RSA 261:45 and RSA 263:35. Most town clerk offices recommend registering the vehicle first and getting the license the same visit, since both can typically be handled together.
Can I register to vote and become a New Hampshire resident on the same day?+
For voting purposes, yes: New Hampshire allows same-day registration, including at the polls on Election Day, as long as you can show proof of domicile (a New Hampshire driver's license, non-driver ID, or vehicle registration at your domicile address all qualify). Tax residency is a separate, broader question turning on RSA 21:6-a's actions-based domicile standard, not just the voter-registration moment.
