You’ve probably heard mixed things about suppressors in Washington State. Are they legal? Do you need special paperwork? Can you hunt with one? Honestly, this topic confuses a lot of people. Let’s clear it all up right now.
This guide covers everything you need to know about owning a suppressor in Washington in 2026. We’ll talk about state law, federal rules, the big federal change that happened this year, and what happens if you break the rules.
What Is a Suppressor?
A suppressor is a device that attaches to a firearm’s barrel. It reduces the noise the gun makes when fired. People also call them silencers, though that term is a bit misleading. They don’t make guns silent. They just make them quieter.
Think of it like a car muffler. It dampens the sound. It doesn’t eliminate it.
Suppressors are regulated at both the state and federal level. That means you have to follow two sets of rules to own one legally. Pretty straightforward so far, right?
Are Suppressors Legal in Washington State?
Yes. Suppressors are legal to own in Washington. But there’s a catch.
Washington state law, under RCW 9.41.250, says it is generally unlawful to use any device that suppresses the noise of a firearm. However, the same law carves out a key exception. You can own and use a suppressor if it is legally registered and possessed in accordance with federal law.
So suppressors are legal in Washington, but only if you follow the federal registration process. Skip the federal paperwork, and you are breaking both federal and state law at the same time.
Wondering what that federal process looks like? Keep reading.
Federal Law: The NFA Rules You Must Follow
The National Firearms Act, or NFA, has regulated suppressors since 1934. Suppressors are classified as NFA items. That means buying one involves more steps than buying a regular firearm.
Here is what the federal process requires:
You must submit an ATF Form 4 to the Bureau of Alcohol, Tobacco, Firearms and Explosives. You must pass a thorough background check. You also need to submit fingerprints and passport-style photos. Once approved, you receive your registration documents. You keep those records as proof of legal ownership.
Okay, pause. Here is a big update.
The 2026 Federal Change: No More $200 Tax Stamp
This one’s actually huge. For over 90 years, buying a suppressor meant paying a $200 federal tax stamp on top of the purchase price. That changed in 2026.
President Trump signed the One Big Beautiful Bill Act into law on July 4, 2025. Starting January 1, 2026, the $200 tax stamp for suppressors was eliminated. The fee dropped to $0.
You still have to submit ATF paperwork and pass a background check. Registration is still required. The process is basically the same. But that $200 payment is gone. That means owning a suppressor in Washington just got $200 cheaper. Not a bad deal.
Many people had been waiting for this change. Once it took effect, suppressor purchases surged. The ATF has been dealing with higher application volumes in 2026. Expect some processing delays if you apply now.
Who Can Legally Own a Suppressor in Washington?
Not everyone qualifies. Both federal and state law set clear limits on who can own any firearm, including suppressors.
You generally cannot own a suppressor if you have a felony conviction. People with certain misdemeanor convictions, including domestic violence offenses, are also prohibited. Other disqualifying factors include being a fugitive, having certain mental health adjudications, or being in the country illegally.
You’re not alone if this list surprises you. Most people assume restrictions only apply to handguns. Suppressors fall under the same rules.
Can You Hunt With a Suppressor in Washington?
Hold on, this part is important.
This is one of the most asked questions about suppressors in Washington. The answer has some nuance. State law and hunting regulations interact in a way that creates real confusion.
According to multiple sources, Washington’s hunting regulations have historically restricted suppressor use while hunting, despite suppressors being legal to own. Some recent sources suggest those rules may be shifting, but it is critical that you verify this directly with the Washington Department of Fish and Wildlife before you hunt with a suppressor.
You can reach WDFW at (360) 902-2200 or visit their website at wdfw.wa.gov. Hunting regulations change season to season. Always check the most current pamphlet before heading out.
What is clear is this: suppressors are fully legal for target shooting, range use, and home defense in Washington. Those uses have no added restrictions beyond the standard federal registration requirement.
Can You Use a Suppressor on an Assault Weapon in Washington?
This is where things get more complicated. Washington has strict assault weapon laws. Under the state’s assault weapon ban, certain semiautomatic firearms are restricted.
Washington’s definition of an assault weapon includes specific features. Sound suppressors and silencers are actually listed as features that can make a firearm fall into the assault weapon category under the state’s definitions.
In practical terms, this means you need to be careful. Attaching a suppressor to a firearm that already has other restricted features could create a legal problem. If you are unsure about a specific firearm and suppressor combination, consult a licensed attorney who specializes in Washington firearms law.
What Happens If You Violate the Law?
Let’s talk about the penalties. This is where things get serious.
Under Washington state law, using a suppressor that is not legally registered under federal law is a gross misdemeanor. Think of it like a serious traffic violation, but more serious. A gross misdemeanor in Washington can result in up to 364 days in jail and a fine of up to $5,000.
On the federal side, possessing an unregistered NFA item is a much heavier charge. Federal law makes it a felony punishable by up to 10 years in federal prison and fines up to $250,000. That is a massive difference in consequences. Totally not worth the risk.
So if you skip the ATF paperwork and just buy a suppressor privately without registering it, you are looking at serious trouble at both the state and federal level. Just do it right the first time.
How to Legally Buy a Suppressor in Washington
Good news. The process is manageable. Here is how you do it step by step.
Start by finding a licensed NFA dealer in Washington. You can find dealers through the ATF’s database or through suppressor retailers like Silencer Shop or Silencer Central. Many of these dealers handle all the paperwork for you.
Next, choose your suppressor and complete the ATF Form 4. Your dealer will help you with this. You will submit fingerprints, photos, and pass a background check. As of 2026, you no longer pay the $200 tax. Wait for ATF approval, then pick up your suppressor.
Trust me, working with an experienced dealer makes the whole process much easier. They do this every day.
One more thing: once approved, always keep your registration documents with the suppressor or readily accessible. You should be able to prove it is registered if ever asked.
What About NFA Gun Trusts?
You may hear people mention NFA gun trusts. A trust is a legal document that allows multiple people to legally possess your suppressor. For example, it could allow family members to use it without you being present.
Without a trust, only the registered owner can possess the suppressor. With a trust, named members can legally handle and use it.
This is not required. But if you want other household members to be able to use your suppressor legally, a trust is worth considering. Talk to an NFA attorney or a knowledgeable dealer about whether this makes sense for you.
Transporting a Suppressor in Washington
You can legally transport your registered suppressor in a vehicle in Washington. The key is that it must be legally owned and properly registered. Follow standard safe transportation practices for firearms. Keep your registration documents accessible.
Makes sense, right? The same legal standards that apply to possessing a suppressor apply to transporting it.

Final Thoughts

That is the biggest change to suppressor law in decades. The registration process still applies, but the financial barrier is lower than it has ever been.
If you are thinking about buying a suppressor, work with a licensed NFA dealer. They will walk you through the paperwork and make sure everything is done right. And if you plan to hunt with one, always check the current WDFW regulations first.
Now you know the basics. Stay informed, follow the rules, and when in doubt, ask a qualified firearms attorney or contact the ATF directly.
