ATF Form Types
✓ January 1, 2026 — $0 Tax Stamp: The One Big Beautiful Bill Act eliminated the $200 NFA transfer tax for suppressors, SBRs, SBSs, and AOWs. Machine guns and destructive devices are NOT included. The registration process — eForm, background check, fingerprints, ATF approval before possession — remains fully required.
01
NFA Item Types
What qualifies as an NFA item and what form each requires
Suppressor
Any device for silencing or diminishing the report of a portable firearm. Includes solvent trap kits when assembled as a suppressor.
Buy: Form 4 · Build: Form 1 · Dealer transfer: Form 3
Short Barrel Rifle
Rifle with barrel under 16" or overall length under 26". Includes adding a stock to a pistol with sub-16" barrel.
Buy: Form 4 · Convert/Build: Form 1 · Dealer transfer: Form 3
Short Barrel Shotgun
Shotgun with barrel under 18" or overall length under 26". Same NFA process as SBR — requires separate ATF approval.
Buy: Form 4 · Build: Form 1 · Dealer transfer: Form 3
Any Other Weapon
Pistols with vertical foregrips, smooth-bore pistols, pen guns, and certain concealable firearms not fitting pistol/rifle/shotgun definitions.
Buy: Form 4 ($5 tax) · Build: Form 1 ($200 tax) · Dealer: Form 3
Machine Gun
Fires more than one round per trigger pull. Civilian transfer of post-May-19-1986 machine guns is prohibited by federal law. Pre-1986 registered MGs are transferable but extremely expensive.
Buy pre-1986: Form 4 · $0 stamp does NOT apply to machine guns
Destructive Device
Explosives, grenades, rockets, large-bore firearms (bore over half inch). Civilian ownership is effectively prohibited or requires special licensing for most DD items.
Buy: Form 4 · $0 stamp does NOT apply to destructive devices
⚠ AOW Tax Exception: AOW Form 4 transfers use a $5 tax stamp — not $200, not $0. If you build an AOW yourself via Form 1, the $200 stamp applies (now $0 under the 2026 change). Suppressors, SBRs, and SBSs all use $0 as of Jan 1, 2026.
02
Which Form Do You Need?
eForm 1, Form 3, eForm 4, and Form 5 — when each applies
Most Common — Buy
Form 4
Application for Tax-Paid Transfer
Used when a private citizen purchases a manufactured NFA item from a dealer or another individual. The item stays at the dealer until ATF approves your Form 4.
- Tax: $0 effective January 1, 2026 (was $200)
- Used for: Buying suppressors, SBRs, SBSs, AOWs from licensed FFL/SOT dealers
- Who files: You and your Class III dealer together at eForms.atf.gov
- Requires: Background check, fingerprints, photo, demographic info
- Wait: Days to a few weeks for eForm submissions in 2026
- Trust or Individual: Both options available on eForm 4
Build Your Own
Form 1
Application to Make and Register
Used when a private citizen makes or converts an NFA item — building a suppressor from a solvent trap kit, converting a pistol to SBR, or making an AOW.
- Tax: $0 effective January 1, 2026
- Used for: Building suppressors, converting pistols to SBR, making AOWs from scratch
- Who files: You directly at eForms.atf.gov — no dealer required to initiate
- Requires: Background check, fingerprints, photo, serial number engraving plan
- Wait: Generally faster than Form 4 — often just days
- Critical: Do NOT begin building until your Form 1 is approved. Building before approval is a federal felony.
Dealer-to-Dealer
Form 3
Tax-Exempt Transfer Between SOT Dealers
Used when an NFA item moves between two FFL dealers with SOT status. This is how manufacturers ship items to local dealers. You never file Form 3 — your dealer does.
- Tax: Always $0 — this transfer is inherently tax-exempt
- Used for: Manufacturer to distributor to your local FFL/SOT dealer
- Who files: The sending dealer. You have no role in this form.
- Wait: Typically under 2 weeks — fast dealer-to-dealer channel
- What it means for you: When you order online, the suppressor moves to your local dealer via Form 3 first. Then you file Form 4 for the final transfer to you.
Estate / Government
Form 5
Tax-Exempt Transfer — Inheritance or Government
Used for tax-exempt transfers — primarily when an NFA owner passes away and heirs inherit the item, or for transfers to government entities.
- Tax: Always $0 — this transfer is tax-exempt
- Used for: Heirs inheriting NFA items from an individual owner's estate; transfers to law enforcement or government
- Trust advantage: NFA items owned by a trust pass to beneficiaries without a new Form 4 or Form 5 — a major reason to use a trust
- Individual owners: Your heirs will need Form 5 when you pass — another argument for trust registration
Quick decision: Buying a manufactured suppressor or SBR from a dealer → Form 4. Building your own → Form 1. Dealer moving it to their location → Form 3 (they handle it). Heirs inheriting it → Form 5.
03
Trust vs Individual
How you register it — this decision has permanent implications
Recommended for Most
NFA Gun Trust
A legal entity that owns the NFA item. Multiple "responsible persons" can legally possess and use it. Best for anyone with family, hunting partners, or estate planning concerns.
- Shared possession: Spouse, adult children, partners listed as responsible persons can all legally use it
- Estate planning: Passes to trust beneficiaries without a new Form 4 — far simpler than individual inheritance via Form 5
- Future flexibility: Add or remove responsible persons via trust amendment with no ATF involvement
- Remote certification: Trust filers can certify eForm 4 remotely — no in-person dealer visit required for your signature
- More upfront paperwork — all responsible persons submit photos, prints, background checks
- Slightly more complex setup — most dealers offer trust setup free or very cheaply
Solo Shooter
Individual Filing
Registered to you personally. Simplest paperwork path. Best if you are the only person who will ever use the item and estate planning is not a priority.
- Simpler process: Less paperwork, fewer moving parts at submission
- Marginally faster: Individual eForm 4 approvals slightly faster than trust in 2026
- Only you can legally possess it — not your spouse, adult children, or anyone else
- Lending it to someone — even briefly — is illegal under federal law
- After your death, heirs must file Form 5 (tax-exempt but still paperwork and time)
- Transferring to a trust later requires a brand new Form 4 filing
- Must certify Form 4 in person at the dealer — remote certification not available for individuals
Bottom line: If there is any chance someone else will use it, or you care about what happens to it when you're gone — get the trust. The paperwork difference is one afternoon. The flexibility difference is permanent. Most dealers will set up a basic NFA trust at no charge.

Processing Time Estimator
Current ATF eForm wait times as of early 2026 — estimates only, actual times vary
⚠ Surge expected in 2026: The $0 tax stamp change is driving a significant surge in NFA applications. ATF is preparing for higher volume. Times below reflect the pre-surge early 2026 baseline — expect increases as the year progresses. File early if you are planning a purchase.
eForm 4 — Individual
3–14 days
Early 2026 baseline · Pre-surge
Historically fast eForm individual approvals. Expect this window to widen as the $0 stamp surge fully hits ATF volume through 2026.
eForm 4 — Trust
7–21 days
Early 2026 baseline · Pre-surge
Marginally longer than individual due to additional responsible person verification. Still dramatically faster than historical wait times of 6–12 months.
eForm 1 — Individual or Trust
1–10 days
Generally fastest NFA eForm path
Form 1 approvals are currently the fastest path. Complete all forms accurately — errors cause delays regardless of form type or submission method.
Paper Form 4 (mail-in)
3–12+ months
Avoid unless eForm is unavailable
Paper forms are dramatically slower than eForms. Always use ATF eForms at eForms.atf.gov when possible. Paper is effectively a legacy path at this point.
Fastest approval path: Accurate form → digital fingerprints via kiosk → immediate electronic signature → eForm submission. Every delay in signatures or demographic errors extends your wait. Your full legal name, DOB, and address must match your government-issued ID exactly.

The Full Process
From purchase decision to range day — every step
1
Verify Your State Allows It
Use the state checker in Section 05 above. If your state bans the NFA item type, ATF will not approve a Form 1 or Form 4 for a resident of that state. There is no exception — federal NFA compliance does not override a state ban.
2
Decide: Trust or Individual Before You Buy
Make this decision before you start any paperwork. If filing as a trust, get your trust set up with your dealer or a legal service first. Changing your registration method after submission requires a brand new filing.
3
Select Item and Find a Class III Dealer
You need an FFL with SOT status — commonly called a Class III dealer. You can buy locally or order online and have the item shipped to a local Class III FFL. The item stays at the dealer while your Form 4 is pending.
Online purchase flow: Order from a retailer → they ship via Form 3 to your local FFL/SOT → you file Form 4 at the local dealer for the final transfer to you. Dealer transfer fees typically run $50–100.
4
Submit ATF eForm $0 Tax 2026
Your dealer initiates eForm 4 (or you file eForm 1 for building) at eForms.atf.gov. You provide your demographic info, photo, and fingerprints. The $200 tax payment step is gone as of January 1, 2026. Review every field carefully before certifying — errors are the number one cause of delays.
Fingerprints: Many dealers have a Silencer Shop kiosk for digital fingerprint submission. If not, use a local fingerprinting service with ink cards. Digital fingerprints process faster.
5
Wait for ATF Approval
ATF runs your background check and reviews the application. Monitor status at eForms.atf.gov or ask your dealer. You will receive an email notification when approved. Do not contact ATF to check status — it does not speed up the process.
6
Pick Up and Keep Your Paperwork
Once approved, ATF emails the dealer your approved Form. You complete the final transfer and take your item home. Keep a copy of your approved Form accessible whenever you use or transport the NFA item.
Interstate transport: Suppressors and SBSs do not require ATF Form 5320.20 for travel across state lines. SBRs, machine guns, and destructive devices DO require prior ATF notification via Form 5320.20 before crossing state lines.
07
Submission Checklist
Everything needed before certifying your eForm — errors are the number one cause of delays
State verified: Confirmed your state allows this NFA item type before purchasing or beginning the process
Trust or individual decided: Made your registration method decision before starting paperwork
ATF eForms account created: Account set up at eForms.atf.gov before going to the dealer
Fingerprints collected: Digital prints via kiosk, or ink fingerprint cards ready for mail submission
Photo ready: Current passport-style photo, matching your government ID appearance
Name matches ID exactly: Full legal name on form is identical to your government-issued photo ID — middle name, suffix, everything
Address is current: Residence address matches your ID or most recent address if you have moved
Date of birth correct: DOB matches your government ID exactly — a single digit error causes a delay and possible denial
Trust documents ready (trust filers): Signed, executed trust document ready for submission. All responsible persons have submitted their background check info.
Form 1 serial number planned (builders): If building, serial number format confirmed and engraving planned before submission — must contain a letter and a number, no special characters
eForm reviewed before certifying: Every field double-checked — name, DOB, address, item description, serial number, dealer info all match your records
Certification completed: Form certified at eForms.atf.gov — individual filers in-person at dealer, trust filers may certify remotely
Wait confirmed: Item stays at the dealer (Form 4) or unbuilt (Form 1) until ATF approval arrives — possession before approval is a federal felony regardless of how long you have been waiting
