Could the NFA Registration Requirement Be Struck Down? The 2026 Lawsuits Explained

For most of its history, the National Firearms Act has been understood primarily as a tax statute, sustained under Congress's taxing power. When Congress eliminated the $200 making and transfer tax on most NFA items effective January 1, 2026, a coordinated wave of litigation followed, arguing that once the tax was zeroed out, the constitutional footing for the remaining registration regime became far more vulnerable. If there is no tax, the plaintiffs ask, what is left to support the registry?

That question is being actively litigated right now in multiple federal courts, and the next several weeks are likely to bring important developments in at least two of the leading cases. This article explains what is being challenged, what the government is arguing in response, and — most importantly — what a ruling would and would not change for the ordinary suppressor or short-barreled rifle owner.

The Legal Theory Behind the Challenges

The NFA was enacted in 1934 as a revenue measure. The Supreme Court upheld it three years later in Sonzinsky v. United States precisely because it was framed as a tax, not as a freestanding regulation of firearms. The registration and transfer-approval provisions were historically defended as part of the statute's tax-enforcement machinery.

The plaintiffs' core argument is straightforward: a tax of zero dollars is not a tax at all. If the constitutional justification for the registry was the collection of the making and transfer tax, and that tax has been reduced to nothing, then — in their view — the registration requirement for the affected items has lost its constitutional anchor. The challenges also raise a Second Amendment theory, arguing that suppressors and short-barreled rifles are "arms" in common use and that there is no historical tradition supporting their registration.

The Cases to Watch

Several suits are proceeding in parallel, deliberately filed in different districts and circuits so that more than one court — and potentially more than one court of appeals — weighs in:

Silencer Shop Foundation v. ATF (Northern District of Texas, San Angelo Division). Filed July 4, 2025 by the Silencer Shop Foundation, Gun Owners of America, the Firearms Regulatory Accountability Coalition, several manufacturers, and more than a dozen states. Cross-motions for summary judgment are fully briefed, with argument scheduled for early July 2026. A related case, Jensen v. ATF, has been consolidated into it.

Brown v. ATF (Eastern District of Missouri). Filed August 1, 2025 by the Second Amendment Foundation, the Firearms Policy Coalition, the NRA, and the American Suppressor Association. The court found the case raised novel issues, ordered supplemental briefing, and set oral argument on the summary-judgment motions for late June 2026.

Roberts v. ATF (Eastern District of Kentucky). Filed February 2026 with the Buckeye Firearms Association and the American Suppressor Association Foundation among the plaintiffs. The plaintiffs have filed for summary judgment, advancing the same essential theory.

The spread across districts is strategic. If two appellate circuits ultimately disagree, a split substantially raises the odds that the Supreme Court will take up the question.

What the Government Is Arguing

It would be a mistake to treat these cases as a foregone conclusion, and a responsible reading of the situation has to account for the government's response. The Department of Justice and ATF have filed cross-motions defending the statute on several independent grounds.

First, they argue the registration requirements remain tied to a valid taxing scheme because manufacturers and dealers of NFA items still pay a special occupational tax, and the registry helps ensure that those taxes are paid. Second, they argue the requirements are independently valid under the Commerce Clause as a regulation of items moving in interstate commerce. Third, on the Second Amendment, they contend that the right does not extend to categories of firearms not "typically possessed by law-abiding citizens for lawful purposes," a standard they argue applies to short-barreled weapons and suppressors.

In other words, the "no tax, no NFA" framing that circulates online is an oversimplification. The taxing power was the historical foundation, but the government is no longer relying on it alone. A court could accept the plaintiffs' taxing-power argument and still uphold the registry on Commerce Clause grounds.

The government also points to the legislative history: during the 2025 reconciliation debate, Congress considered language that would have repealed the registration requirements for these items and chose not to enact it. The government argues that this cuts against reading the tax change as an implied decision to dismantle the registry. Plaintiffs read the same history differently. The point for a reader is simply that the outcome is genuinely contested, not preordained.

What a Win Would — and Would Not — Change

Assume, for the sake of analysis, that the plaintiffs prevail in one of these cases. Several things would still be true.

A district court win is not a national repeal. A favorable ruling binds the parties and applies within that court's reach, but it does not instantly erase the NFA nationwide. And even if a court grants relief, the scope matters: an as-applied ruling, a plaintiff-limited injunction, or a geographically limited order can produce a very different practical result than a nationwide injunction. If the government appeals — which it would — it would almost certainly seek a stay keeping the current rules in place during the appeal. The practical status quo could remain unchanged for a long time.

State law is untouched. A federal ruling on the NFA does not override state restrictions. Several states ban or heavily regulate suppressors and short-barreled rifles independently, and those laws would survive regardless of what happens to the federal registry. Owners in Maryland, Virginia, and the District of Columbia in particular should not assume a federal win changes their state-law exposure.

A deregulation gap could create its own problems. If federal registration for suppressors disappeared while some state statutes still keyed legality to a valid federal registration, owners could find themselves in an awkward transitional position. This is not a reason for alarm, but it is a reason to wait for clear guidance rather than acting on a headline.

What This Means If You Own — or Are Buying — NFA Items

For now, nothing about your obligations has changed. The $200 tax is gone for most items, but Form 1 and Form 4 applications, background checks, fingerprints, and ATF approval all remain in place. Until a court rules and any appeals are resolved, the registration system is fully in effect and must be followed exactly as before.

It is also worth saying plainly: do not make or possess an unregistered NFA item in anticipation of a favorable ruling. A pending lawsuit is not a change in the law, and the consequences of guessing wrong are severe. The prudent course is to keep complying with current requirements and watch for actual decisions.

The Bottom Line

The 2026 NFA lawsuits represent the most serious constitutional challenge to the registration regime in decades, and the timing is genuinely significant: the leading cases have summary-judgment hearings within days of one another. But a hearing is not a ruling, a district-court ruling is not a final judgment, and even a final judgment would face appeal and would not disturb state law.

The honest assessment is that this is a real and consequential fight with an uncertain outcome — not a settled victory. Owners and prospective buyers are best served by continuing to comply with the existing framework while these cases work through the courts, and by getting individualized guidance before making any decision that depends on how the litigation turns out.
