How to Buy a Suppressor: Complete Guide for Firearm Owners

Purchasing a suppressor legally in the United States requires navigating federal regulations and the National Firearms Act (NFA) process. This comprehensive guide walks you through exactly what is required to buy a suppressor, from understanding federal laws to obtaining your Form 4 approval. Yankee Hill Machine works with trusted federally licensed dealers nationwide to guide you through every step of your suppressor purchase.

As of January 1, 2026, federal tax treatment and NFA regulation of suppressors has changed. The previous $200 tax stamp requirement and suppressor registration requirement have been eliminated. However, Form 4 submission, fingerprints, photographs, and background checks still apply under the current federal process.

If you are navigating a suppressor purchase under the updated rules, it is important to understand which legacy requirements have been removed and which compliance steps remain in place.

Yes, suppressors are legal to own under federal law in the United States. Suppressors are regulated under the National Firearms Act (NFA) and overseen by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). The previous $200 tax payment has been eliminated and the current Form 4 tax is $0, but suppressors remain NFA firearms and still require an approved Form 4, fingerprints, photographs, and a background check before transfer.

However, suppressor ownership varies by state law. Before beginning the purchase process, verify that suppressors are legal in your state of residence and any states where you plan to use the device.

When the required federal process is properly completed through a licensed dealer, suppressor ownership is fully legal under federal law. Licensed dealers ensure all transfers comply with applicable federal and state regulations.

The process to legally purchase your device involves several sequential steps:

• Choose Your Suppressor - Select a suppressor that matches your intended caliber, cartridge(s) and uses
• Find a Licensed SOT Dealer - Locate a federally licensed firearms dealer with Special Occupational Tax (SOT) status that can handle NFA transfers in your area
• Order Through Your Dealer - Have your chosen dealer order the suppressor, as they must have physical possession before you can begin the ATF process
• Decide on Registration Method - Choose between individual registration or creating an NFA gun trust (trusts offer privacy and succession benefits)
• Complete ATF Form 4 - Fill out the Application for Tax Paid Transfer and Registration of Firearm with accurate information
• Submit Required Documentation - Provide fingerprint cards, passport-style photos, and a copy of your driver's license or state ID
• Wait for ATF Approval - Processing times change regularly so this can take anywhere from a couple of weeks to 12 months or more depending on how many applications are submitted at any given time
• Complete Background Check - The ATF conducts an extensive background investigation during processing
• Take Legal Possession - Once approved, return to your dealer to complete the transfer and take possession of your suppressor

NFA Trust or Individual Registration

You must choose between individual registration or establishing an NFA gun trust. Individual registration is simpler but offers less privacy, as your information becomes part of public records. NFA trusts provide privacy protection, allow multiple trustees, and simplify succession planning if something happens to the original owner.

Required Documents and Forms

The ATF requires specific documentation for suppressor purchases:

• Completed ATF Form 4
• Two FBI FD-258 fingerprint cards completed by a qualified technician
• Two passport-style photographs taken within the past year
• Copy of government-issued photo identification

If using an NFA trust, you'll also need certified copies of your trust documents and fingerprints/photos for all responsible persons listed in the trust.

Suppressors must be purchased through federally licensed firearms dealers with Special Occupational Tax (SOT) status. Many SOT dealers specialize in NFA item transfers, ensuring your suppressor purchase meets all legal requirements. Online purchases are possible, but the suppressor must be transferred through a local SOT dealer in your area.
