For many firearm owners in North Idaho, the term “gun trust” sounds more complicated than it needs to be. But if you own—or are considering purchasing—a suppressor, short-barreled rifle, short-barreled shotgun, or another firearm regulated under the National Firearms Act, understanding how a trust works can be an important part of responsible ownership.

On North Idaho Experience, Eric and the team sat down with local attorney Ben Allen to discuss Idaho gun trusts and NFA law, including how these trusts developed, why firearm owners use them, and how they can help with shared possession and estate planning.

As Allen emphasized during the conversation, firearm laws can be complicated and highly dependent on individual circumstances. This information is educational and should not be considered legal advice.

What Is a Gun Trust?

A gun trust is a legal trust designed to own firearms and related assets. In Idaho, when people talk about gun trusts, they are usually referring specifically to an NFA trust.

The [National Firearms Act (NFA)] governs certain federally regulated firearms and devices, including suppressors, short-barreled rifles, short-barreled shotguns, machine guns, destructive devices, and firearms classified as “any other weapon.”

For most ordinary firearms, Idaho gun owners generally do not need a specialized trust simply to possess the firearm. A non-NFA gun trust may still play a role in estate planning or asset management, but NFA-regulated items are where trusts become particularly relevant.

Why the National Firearms Act Still Matters

The National Firearms Act dates back to 1934 and represented one of the federal government’s earliest major efforts to regulate certain categories of firearms.

Rather than creating a simple prohibition, the law established a registration and taxation system. For decades, that included the well-known $200 tax associated with many NFA firearms.

That $200 figure was especially significant when the law was enacted. In the 1930s, it could equal or exceed the cost of the firearm itself, creating a substantial barrier to ownership.

Federal law has changed considerably since then. As of 2026, ATF regulations establish a $0 making or transfer tax for NFA firearms other than machine guns and destructive devices. However, the federal registration, application, and approval requirements associated with covered NFA firearms remain in place.

Why Would Someone Use an NFA Trust?

One of the biggest issues with individually owned NFA firearms is determining who can legally possess them.

When an NFA-regulated firearm is registered to one individual, that registration is tied to that person. That can create complications for households in which multiple family members may otherwise have access to firearms.

A properly drafted gun trust creates a separate legal entity that owns the regulated property. Qualified trustees may then have lawful authority to possess trust-owned items, subject to applicable federal and state law.

That can make a trust useful for firearm owners who want to involve a spouse or other qualified family members in managing or possessing NFA property.

However, simply adding someone to a trust does not automatically make every form of possession lawful. Trustees and other responsible persons must still satisfy applicable legal requirements.

Gun Trusts and Estate Planning

Estate planning is another major reason Idaho firearm owners consider a gun trust.

If someone individually owns an NFA firearm and dies, the firearm can become part of the estate. That creates additional legal and administrative steps while the estate is being handled.

As Allen explained in the interview, ATF Form 5 may be used in certain estate-related transfers involving NFA firearms.

With a properly structured trust, the trust itself continues to own the firearm even when the person who originally established or managed the trust dies. A succession plan can establish who becomes the next trustee and how trust property will ultimately be handled.

For families with a substantial firearm collection, this can make long-term planning significantly more organized.

It can also help answer important questions before they become problems: Who is legally responsible for the firearms? Who should eventually receive them? What happens if a beneficiary is too young or otherwise prohibited from possessing a particular firearm?

Those are issues best addressed while the firearm owner is still able to make those decisions.

What Changed for Gun Trusts in 2016?

Gun trusts were once especially popular because applicants using trusts did not have the same individual disclosure requirements that exist today.

That changed with federal Rule 41F, which took effect in 2016.

The rule established identification and background-check requirements for certain “responsible persons” associated with trusts and other legal entities. At the same time, it removed the former requirement for an applicant to obtain a chief law enforcement officer’s certification and replaced it with a notification requirement.

In other words, trusts can still offer important ownership and estate-planning benefits, but they should not be viewed as a way to anonymously bypass the NFA application process.

Traveling With NFA Firearms

Another topic discussed during the North Idaho Experience interview was interstate travel.

This is particularly important for Idaho residents because a short drive can take you into Washington, Oregon, Montana, or another state with a different set of firearm laws.

Federal registration does not override more restrictive state law.

Certain NFA firearms can also require additional federal authorization before interstate transportation. Anyone planning to cross state lines with an NFA-regulated firearm should research both the destination and every applicable transportation requirement before traveling.

The safest approach is to confirm the rules for the specific firearm and destination rather than assuming Idaho law follows you across state lines.

Can You Move Existing NFA Items Into a Trust?

What if you already own a suppressor or short-barreled firearm individually and decide later that a trust makes sense?

As discussed in the interview, an existing individually registered NFA item can potentially be transferred into a trust, but placing an item into the trust is itself a legal transfer. That means the appropriate ATF process must be completed rather than simply adding the firearm to a list of trust assets.

ATF now provides electronic filing for several NFA forms through [ATF eForms], which can simplify portions of the application process.

This is another area where getting guidance before moving an existing firearm can prevent an expensive or potentially serious mistake.

Is an Idaho Gun Trust Right for You?

A gun trust is not necessary for every firearm owner. But for someone who owns multiple NFA items, wants qualified family members to have access to those items, or wants a clear succession plan for a firearm collection, it may provide meaningful benefits.

The larger lesson from the conversation with Ben Allen is that NFA ownership is about more than purchasing a firearm or suppressor. You also need to think about possession, registration, family access, travel, and what happens to those assets after your death.

Because both federal regulations and individual circumstances can change, firearm owners should work with an Idaho attorney familiar with NFA law when creating or modifying a gun trust.

Understanding the rules before purchasing, transferring, traveling with, or passing down an NFA firearm can help protect both your property and the people you intend to share it with.
