The National Rifle Association (NRA) has filed a lawsuit against the state of Colorado, seeking to overturn a newly approved firearm and ammunition excise tax. The tax, passed by voters in November 2024, aims to fund violence prevention programs and enhance public safety initiatives.
The NRA argues that the measure violates Second Amendment rights and places an unconstitutional financial burden on gun owners. The legal battle is expected to be a high-profile case, potentially influencing future gun laws across the country.
Colorado Voters Approve Firearm Excise Tax
In the 2024 election, Colorado voters narrowly approved a 10% excise tax on the sale of firearms and ammunition. The tax, set to take effect in July 2025, is expected to generate millions in revenue for programs aimed at reducing gun violence and improving mental health services.
State officials argue that the tax is a reasonable measure to help offset the costs of gun-related incidents, including:
✅ Increased law enforcement expenses
✅ Medical costs for shooting victims
✅ Community intervention programs
However, gun rights advocates, including the NRA, claim the tax is an unfair penalty on law-abiding gun owners.
The NRA’s Legal Argument
The NRA’s lawsuit, filed in federal court, makes several key claims:
1. Violation of the Second Amendment
The NRA argues that taxing firearms and ammunition infringes on the constitutional right to bear arms. They compare it to placing a special tax on free speech or voting, which would be considered unconstitutional.
2. Disproportionate Impact on Low-Income Gun Owners
Gun rights groups claim the tax unfairly affects low-income residents, making it harder for them to exercise their Second Amendment rights.
3. Legal Precedent and Supreme Court Implications
The case could set a legal precedent on whether states can impose special taxes on firearms. If the NRA wins, it could limit the ability of states to introduce similar firearm-related taxes in the future.
Colorado’s Response: Tax Revenue for Public Safety
Supporters of the tax, including Governor Jared Polis, argue that the measure is a common-sense approach to addressing gun violence. They emphasize that:
- Firearm ownership is not restricted, only taxed.
- The revenue is earmarked for gun safety programs, not general state spending.
- Similar taxes exist on alcohol and tobacco to help mitigate public health risks.
Proponents point to other states that have implemented similar taxes, such as California and Washington, to support gun-related safety initiatives.

Other States with Firearm and Ammunition Taxes
Colorado is not the first state to impose an excise tax on firearms. Here’s a look at how other states handle similar policies:
- California: Implements an 11% excise tax on firearm and ammunition sales, funding school safety programs and gun violence prevention.
- Washington: Enforces a $25 tax per firearm sale, along with a per-round ammunition tax.
- Illinois: Charges an additional fee on firearm dealers, with revenue going to state law enforcement agencies.
The outcome of the NRA lawsuit could impact existing laws in these states and influence future gun policy nationwide.
What Happens Next?
Legal Proceedings Underway
The lawsuit is expected to move through the federal court system, with a decision potentially being appealed to the U.S. Supreme Court.
Implications for Gun Owners
If the NRA wins, Colorado’s excise tax could be overturned, preventing the state from collecting revenue for violence prevention programs.
If the state prevails, the tax will remain in effect, potentially encouraging other states to adopt similar measures.
Conclusion: A Case That Could Shape Future Gun Laws
The NRA’s lawsuit against Colorado’s firearm and ammunition excise tax is set to become a landmark case in the ongoing debate over gun control and Second Amendment rights.
As the legal battle unfolds, the case could impact gun laws nationwide, influencing whether states can impose additional taxes on firearms to fund public safety programs.
Gun rights advocates see the tax as unconstitutional, while supporters argue it’s a necessary step to reduce gun-related violence. The final ruling will likely have long-term consequences for both firearm owners and state governments across the U.S.
