Suppressors, New Hampshire, and Dual Residency:
A Path That Stays in New Hampshire

I live in Massachusetts but also stay regularly in New Hampshire. Can I legally purchase and own a suppressor through my New Hampshire residency?

What Massachusetts Law Says

MGL c. 269, Section 10A^[1] prohibits any person from possessing a silencer or suppressor in Massachusetts. There is no exception for NFA-registered items, no licensing pathway, no FOPA-style transit protection, and no suitability override. Possession anywhere in the commonwealth is a felony regardless of federal compliance status. This is the fixed boundary around which the rest of this analysis operates.

The Federal Dual-Residency Framework

The ATF's definition of "state of residence" in 27 C.F.R. Section 478.11^[2] explicitly addresses dual residency: "A person can have two states of residence, e.g., a person maintains a home in State X and a home in State Y and resides in both states; then both State X and State Y are states of residence." The regulation gives the direct example of a person who resides in one state during the week and another on weekends, holding that both qualify. No minimum number of days or nights is specified.

An NFA transfer — a suppressor requires a Form 4 submitted through a licensed dealer with a Special Occupational Tax (SOT) endorsement — must be processed in a state where the buyer is a resident. If New Hampshire qualifies as a genuine state of residence, the transfer can be completed in New Hampshire through a NH dealer. Massachusetts residency does not block the NH transfer. The two states coexist.

What Qualifies as Residency

Section 478.11^[2] addresses the student and rented-room scenario directly: "A student residing away from home may or may not be a resident of the State in which he or she attends school." Whether the student qualifies turns on whether they genuinely reside there — not whether they own property. The same principle applies to any person who rents a room, uses a family member's home, or maintains a cabin: genuine occupancy with intent to make the location a home, however periodic, satisfies the definition.

A lease agreement establishes occupancy but is not government-issued. The practical path to a government-issued NH residency document is NH vehicle registration or a NH driver's license, both issued by NH DMV. NH voter registration (issued by the town clerk) also qualifies. These documents serve as the primary evidence when an FFL/SOT dealer completes the transfer. The lease supports the picture but does not stand alone.

The NFA Transfer Process in New Hampshire

NH RSA Chapter 159-B^[3] expressly permits suppressor ownership in New Hampshire for persons who comply with federal law. The NFA transfer process for an individual buyer requires submitting ATF Form 4 through a NH FFL/SOT dealer, paying the NFA transfer tax (now $0 for a suppressor under the One Big Beautiful Bill Act, effective January 1, 2026; the $200 tax remains only for machine guns and destructive devices), passing the ATF background check, and providing two passport photos and fingerprint cards. Since the ATF's 41F rule took effect in July 2016, individual transfers also require a CLEO notification — the local chief of police or sheriff is notified but does not have approval authority. Current ATF processing times for Form 4 approvals are approximately 10 to 14 months.

During the approval period, the suppressor remains at the dealer. After approval, the item transfers to the buyer in New Hampshire.

The Line That Cannot Be Crossed

This is the structural limit of the path. Federal law permits ownership. New Hampshire law permits ownership. Massachusetts law prohibits possession, and that prohibition contains no NFA exception.

The Firearms Owners' Protection Act, 18 U.S.C. Section 926A^[4], provides interstate transit protection for firearms — not NFA items. Courts have held that FOPA's text covers "firearm" and "ammunition" only. A suppressor transported into Massachusetts, even unloaded and locked, is not protected by FOPA and violates Section 10A.

The suppressor must be stored in New Hampshire, used in New Hampshire, and kept in New Hampshire. Any transport across the state line — for any reason, under any storage condition — creates criminal exposure under MGL c. 269, Section 10A.

NFA Trusts Do Not Change This

NFA trusts allow multiple named trustees to possess an NFA item. A Massachusetts resident who forms an NFA trust and lists a NH address does not resolve the state prohibition. If a trustee possesses the suppressor in Massachusetts, that possession violates Section 10A regardless of the trust's structure or registration status. A trust is a transfer vehicle, not a residency workaround.

Bottom Line

Settled: MGL c. 269, Section 10A prohibits suppressor possession in Massachusetts with no exceptions. 27 C.F.R. Section 478.11 explicitly permits dual residency across two states, and an NFA transfer can be completed in either state of residence. A rented room or periodically occupied property with genuine occupancy intent qualifies as a residence under the regulatory definition. FOPA does not protect NFA items in interstate transit.

Unsettled: No ATF open letter, formal ruling, or First Circuit decision has addressed this precise fact pattern — a MA/NH dual resident purchasing a suppressor in NH. The analysis rests on regulatory text, not a direct precedent.

Do: Establish NH residency with a government-issued NH document before initiating any NFA transfer. NH vehicle registration is the most accessible option for someone renting a room. Complete the transfer through a licensed NH SOT dealer with the NH address on record. Store and use the suppressor in New Hampshire only. Do not transport it into Massachusetts.
