Proposes a constitutional amendment that authorizes a sales tax exemption for ammunition

HJR 120 proposes a constitutional amendment to exempt firearms and ammunition from Missouri's state sales tax. If approved by voters in 2026, it would add a new section to Missouri's Constitution prohibiting state sales tax on these items. The amendment directly affects Missouri residents purchasing firearms or ammunition, as it would remove a tax obligation from those transactions. This change would require voter approval and amend the state constitution, not existing tax law.
