New Hampshire Security Deposit Law: A 2026 Landlord's Guide
How much can you charge in New Hampshire?
1 month's rent or $100. Whichever is greater. Doesn't apply to some small owner-occupied situations.
Returning the deposit: the 30 days deadline
After the tenancy ends, New Hampshire gives you 30 days to return the deposit. Itemization with receipts for repairs. Blowing the deadline is the single most common way landlords lose deposit disputes — courts read these statutes strictly, and in many states a late or missing itemization forfeits your right to keep anything.
What you can deduct
- Unpaid rent and other amounts the lease authorizes
- Damage beyond normal wear and tear — holes in walls, broken fixtures, pet damage
- Never normal wear and tear — faded paint, carpet worn by ordinary use, minor scuffs
The dispute is almost never about the rule — it's about the evidence. Date-stamped move-in and move-out photos plus an itemized statement with receipts is what wins in small-claims court.
Interest and holding requirements
Interest owed if the deposit is held a year or more. Confirm the mechanics in N.H. RSA 540-A:5 to A:8 — interest and account rules are where careful landlords most often slip.

Handling New Hampshire deposits with LandlordPro
LandlordPro keeps a ledger of every deposit you hold — who paid it, which lease it secures, and what happened to it. When a tenancy ends, the settlement workflow records what you returned and what you kept (with reasons), generates a tenant-facing settlement statement, and books any kept portion into your income reports correctly. Combined with the New Hampshire eviction guide and move-in/move-out inspections with photos, you'll have the paper trail that deposit statutes reward.
