Are Suppressors Legal in Indiana?

ATF's current Indiana compendium catalogs the state's machine-gun, transfer, and preemption provisions without a suppressor-specific possession entry. The registered owner or responsible person must still follow the federal NFA transfer and interstate-movement rules applicable to the device and host firearm.

Suppressors are federally legal to own under the NFA. As of January 1, 2026 the One Big Beautiful Bill Act (signed July 2025) zeroed the federal making and transfer tax on suppressors, formerly $200. Form 4 or Form 1, fingerprints, the NICS background check, and NFA registration are all still required; ATF eForm approvals currently run days to a couple of weeks.

Scope: Firearm suppressors (silencers) as defined by the NFA. Federal NFA compliance (Form 4 or Form 1, fingerprints, NICS, registration) is required everywhere they are legal.
