Combatting Antisemitism, Hate and Extremism (Firearms and Customs Laws) Bill 2026
This Bill proposes changes to the tax law to include the national firearms program within the definition of firearms surrender arrangements.
Under the proposed changes, compensation received under the national gun buyback scheme will be treated as non-assessable, non-exempt income. Any capital gain made from this compensation will be disregarded, and no assessable income will arise where compensation exceeds the adjustable value of a surrendered firearm.
