New Hampshire Security Deposit Rules: Caps, Lawful Deductions & Penalties (2026)

How much a landlord can charge, and which deductions are actually legal

At a glance

Who this covers — and who it does not

This page covers how much a landlord may charge in New Hampshire, and which deductions from a residential deposit are lawful. It assumes the tenancy has ended and the question is what may be withheld.

It does not cover:

How much the landlord may charge in the first place

One month's rent (no more than one month's rent or $100, whichever is greater, may be collected beyond the first month's rent) — § 540-A:6(I).

Caps frequently carry exceptions — smaller landlords, furnished units, or pets are treated differently in most states. Read the provision itself rather than relying on the headline figure.

Which deductions the statute permits

Claimed deductionPermitted in New Hampshire
Damages beyond reasonable wear and tear (with itemized list + evidence)Permitted, if substantiated
Unpaid rentPermitted, if substantiated
Tenant's agreed share of real estate tax increasesPermitted, if substantiated
Other lawful charges due under the leasePermitted, if substantiated

Which deductions the statute does not permit

Claimed deductionPermitted in New Hampshire
Reasonable wear and tearNot permitted
Any damage deduction without the itemized list and repair evidenceNot permitted

Whether a specific charge is lawful depends on the facts — how old the damage is, whether the lease addressed it, and whether the landlord can document the cost. A charge being in the "permitted" column does not make it automatically collectable.

Who has to prove what

The landlord must itemize each deduction with particularity and provide satisfactory evidence of repairs. Reasonable wear and tear is not deductible. The tenant must show the tenancy is covered by RSA 540-A to unlock the 2x remedy.

In New Hampshire the burden sits with the landlord. This matters strategically: if the burden is theirs, your task is to request the documentation rather than to prove the deduction wrong. N.H. Rev. Stat. Ann. § 540-A:7(I) ↗

2x deposit + interest (net of lawful charges)

For violating the return or interest requirements, a covered landlord owes twice the deposit plus interest, less lawful charges — a strong remedy, subject to the small-landlord exemption.

N.H. Rev. Stat. Ann. § 540-A:8 ↗

Interest on deposits held 1+ year

A landlord holding a deposit for one year or longer must pay interest at the regular savings-account rate of the depository institution, and must disclose account details on request.

N.H. Rev. Stat. Ann. § 540-A:6(IV) ↗

Common landlord defences and how to answer them

““I'm exempt as a small landlord.””

If you rent a single-family home with no other rentals, or an owner-occupied building of 5 or fewer units (and I'm under 60), the 2x penalty may not apply — but you still owe my deposit under our contract.

N.H. Rev. Stat. Ann. § 540-A:8

““You never gave me a forwarding address.””

Here is my forwarding address now. A landlord is not liable for non-return only if no address was provided; I am providing it in writing.

N.H. Rev. Stat. Ann. § 540-A:8

““I deducted for carpet damage.””

You must provide a written, itemized list with particularity and satisfactory evidence (receipts, estimates, invoices) for each repair. Reasonable wear and tear is not deductible.

Where sources disagree

Some widely circulated summaries of New Hampshire deposit law state things the statute does not say. We list the disagreements rather than picking a side silently.

Some summaries2x the full deposit
N.H. Rev. Stat. Ann. § 540-A:82x (deposit + interest) less payments and lawful charges

What we follow: 2x (deposit + interest) less lawful charges

The statute deducts amounts already paid and lawful charges (unpaid rent, tax share, lease charges) before applying the 2x multiplier.
