How it's counted: Before the next rent due date, running to the end of the 30-day period or the rent period.
How the deadline actually works in New Hampshire
Descriptive-only state. NH's ch. 540 is eviction-framework law phrased to landlords; current guides state the tenant standard as 30 days' written notice with rent owed through the period, and the lease's stated period controls if longer. 540)' descriptively. Military members: tenancy terminates 30 days after the next rent due date with orders attached (RSA 540:11-a).
Worked example: rent due on the 1st, written notice delivered June 10. The earliest compliant termination date is July 31, 2026 — notice must clear the required period and land on a rental-period boundary, which is the step most people miss. Our generator computes this date from your actual rent schedule.
Your lease can require more
State law is the floor, not the ceiling. If your lease requires more notice than the statute (60 days is common in larger complexes), the longer period controls. Read the termination or notice clause before sending anything — a proper letter satisfies both requirements at once.
What notice does your landlord owe you?
The other direction matters too: a New Hampshire landlord ending a month-to-month tenancy generally owes the tenant 30 days (RSA 540:3) (N.H. RSA 540:3). New Hampshire landlords need statutory good cause to evict residential tenants (RSA 540:2) — one of the few statewide just-cause regimes.
Deliver it so it counts
Use a method that creates a record: hand delivery with a signed acknowledgement, or certified mail with return receipt. If your lease names a required delivery method, use that one. Keep a copy of the letter and the receipt — together they are your proof that notice was proper and on time.
