Do I Need an SOT to Sell Suppressors and SBRs Online? What Changed in 2026

Do I need an SOT to sell suppressors and SBRs online, and what changed in 2026? If you are in the business of importing, manufacturing, or dealing in National Firearms Act (NFA) firearms, federal rules still require you to pay a special occupational tax (SOT). What changed in 2026 is the transfer tax on most NFA items and how ATF is treating approval and registration for several categories. State law, and some federal rules on interstate movement, did not go away.

This is the third post in our getting-started series on selling firearms and ammo online. Earlier posts covered whether you need an FFL and how to get one. This is general education, not legal advice. Confirm your plan with ATF, your state, and a firearms attorney before you stock or ship NFA items.

What an SOT is, and when it applies

An SOT is the special occupational tax under the NFA rules in 27 CFR Part 479. Under 27 CFR 479.31, every person who engages in the business of importing, manufacturing, or dealing in (including pawnbrokers) firearms covered by that part must pay the tax.

From that same section:

• The tax is due on or before the day you start the taxable business, and then every year on or before July 1.
• It is not prorated. If you start mid-year, you still owe the full tax year (July 1 through June 30).
• You incur tax liability at each place of business where you run an occupation subject to the tax.

If your online store plans to deal in suppressors, short-barreled rifles (SBRs), short-barreled shotguns (SBSs), or other NFA firearms as a business, this tax sits on top of your federal firearms license. An FFL alone is not the same thing as paying SOT.

Rates and how you pay

27 CFR 479.32 sets the annual rates (except as provided in §479.32a for reduced rates):

• Class 1 importer: $1,000 per year
• Class 2 manufacturer: $1,000 per year
• Class 3 dealer: $500 per year

You pay by return on ATF Form 5630.7 (Special Tax Registration and Return). File that return with payment to meet 26 U.S.C. 5802. Ask your ATF Industry Operations Investigator which class fits before you file.

What changed in 2026: the NFA transfer tax

The biggest statutory change for NFA transfers is in 26 U.S.C. 5811. As amended by Pub. L. 119-21 (July 4, 2025), the transfer tax is $200 for each machinegun or destructive device transferred, and $0 for any other firearm transferred under that section.

The amendment applies to calendar quarters beginning more than 90 days after July 4, 2025, which points to early 2026. Confirm the exact start date with ATF or counsel. Machineguns and destructive devices stay at $200.

A $0 transfer tax is not the same as “NFA items are unregulated,” and it is not the same as dropping SOT. The occupational tax and the transfer tax are different rules.

What changed in October 2026: ATF’s NFA nonenforcement letter

On October 9, 2026, ATF issued an open letter and FAQ on NFA approval and registration for short-barreled rifles, short-barreled shotguns, silencers, and “any other weapons” (AOWs). ATF said it will not enforce NFA approval and registration requirements for those categories. Details are in ATF’s October 9 NFA Open Letter and Florida’s 8th Circuit follow-up.

Three limits matter for online sellers:

1. It is federal nonenforcement. ATF’s FAQ says it cannot say whether an unregistered item satisfies state law. Nonenforcement is an enforcement choice, not a repeal of the NFA, and not a promise that the policy will never change.
2. State law still applies. Federal dealers still have to account for 18 U.S.C. 922(b)(2), which restricts sales that would violate state law at the place of sale or delivery. Some states still tie possession or exemptions to registration in the National Firearms Registration and Transfer Record. Ohio’s R.C. 2923.17(C)(5) is one example. An unregistered SBR can still create state-level exposure. Do not treat a federal FAQ as a statewide green light.
3. Interstate movement rules for SBRs and SBSs are still in the books. 27 CFR 478.28 and related statutes still govern interstate transportation of short-barreled rifles and shotguns. Confirm with ATF whether Form 5320.20 (Form 20) or another authorization still applies. Do not assume the open letter wiped that out.

Leave machineguns and destructive devices out of any “NFA is optional now” talk. The October letter’s categories do not rewrite every NFA rule, and the $200 transfer tax still applies to those two classes.

What this means if you want to sell suppressors or SBRs online

Put the pieces in order before you list inventory:

1. Start with the right FFL. You still need a federal firearms license that matches the business you intend to run. See our posts on needing an FFL and getting one.
2. Add SOT if you will deal in NFA firearms as a business. Pay on Form 5630.7 for each taxable place of business, on the July 1 cycle described above.
3. Map every ship-to state before you advertise. Federal nonenforcement does not answer whether a buyer in a given state can lawfully receive an unregistered suppressor or SBR. Build a state-by-state review with counsel.
4. Separate transfer tax from occupational tax. A $0 transfer tax on many NFA items does not cancel SOT, and it does not cancel state rules.
5. Keep checkout clear about FFL routing. Online stores that sell FFL-required items still need a clear path to a receiving dealer. Automatic FFL can help buyers pick a transfer dealer at checkout on BigCommerce, WooCommerce, or Adobe Commerce / Magento. It does not replace your NFA, SOT, or state-eligibility decisions, and it does not gate NFA items by state for you. Any store copying a “4473-only” shipping model for certain NFA items needs per-state, per-item eligibility review with counsel.

If you only sell Title I firearms and ammunition, you may not need an SOT. If you are unsure whether a product is an NFA firearm, ask ATF or a firearms attorney before you list it.

Bottom line

Yes: if you are in the business of importing, manufacturing, or dealing in NFA firearms, you still need to pay SOT. The main 2026 changes for online sellers are the $0 federal transfer tax on NFA items other than machineguns and destructive devices, and ATF’s October decision not to enforce NFA approval and registration for SBRs, SBSs, silencers, and AOWs at the federal level. SOT, state law, and interstate-movement rules still apply. Treat “what changed” and “what is legal in every state” as different questions.
