The Cost of Freedom: Using the Tax Power to Limit Personal Arsenals

Following the massacre at Sandy Hook Elementary School in Newtown, Connecticut, several state legislatures moved swiftly to create stronger gun control measures, many of them aimed primarily at restricting gun ownership and availability.1  But the Newtown killings highlighted a problem that has not yet been addressed: the accumulation of personal arsenals. Adam Lanza was able to carry out the shootings because he was able to easily access a large cache of weapons; Lanza used two handguns and a rifle in his spree, three of the five weapons in his mother’s legally owned, personal arsenal.2  As the tragedy revealed, personal arsenals make it possible for criminals and unauthorized individuals to obtain a large number of weapons, increasing the threat to public safety. 

Arsenals are on the rise: although gun ownership in the U.S. is declining,3 fewer owners are collecting more weapons, with 20% of gun owners owning 65% of the nation’s guns.4 Even if these owners obtained their guns legally, they disproportionately contribute to the pipeline of guns that end up in the wrong hands. More than 232,400 firearms are stolen each year, with household burglaries accounting for almost three times as many stolen guns as other property crimes.5  Because of stockpiled weapons, 39% of burglaries involving firearms result in the theft of multiple guns,6 the vast majority of which are never recovered.7 These weapons, in turn, are either used in crimes or enter the black market and become a source of weapons for other criminals.8 In effect, personal arsenals offer a jackpot for individuals who would otherwise be unable to legally obtain firearms on their own.9

This article suggests that the federal government can use its taxing power to make it more expensive to build personal arsenals like the one owned by Nancy Lanza in Sandy Hook. Specifically, I argue for an incremental excise tax, which would be imposed on each successive gun after the initial purchase, which would be tax-free. I believe this approach would offer two advantages.  First, given the current constitutional landscape, such a tax would be much harder to challenge than a restriction on gun ownership, which directly implicates the Second Amendment. Second, an incremental tax would distribute the costs of arsenals in proportion to the public safety risk created by each individual gun owner. A tax could be implemented with the adoption of universal background checks without limiting an individual’s choice to own multiple weapons.

Legal Background

In District of Columbia et al. v. Heller, the Supreme Court held that the Second Amendment protects an individual’s right to bear arms, unconnected to a militia, for self-defense in the home.10 Although Heller left open a wide margin for government regulations on commercial gun sales, prohibitions on ownership by the criminals and the mentally ill, and limitations on guns in public places,11 outright restrictions on gun ownership still face an uphill battle moving forward as courts try to delineate the permissible constitutional boundaries of the Second Amendment.12

By contrast, the Supreme Court has consistently upheld broad use of the federal taxing power13 as constitutional, most recently in National Federation of Independent Business et al. v. Sebelius.14 Characterizing the penalty imposed by the Affordable Care Act on individuals who choose not to obtain health insurance as a tax, Chief Justice Roberts emphasized that, while the penalty might affect individual behavior, the “imposition of a tax nonetheless leaves an individual with a lawful choice to do or not do a certain act, so long as he is willing to pay a tax levied on that choice.”15 Because taxes simply “nudge” behavior in a desired direction without directly curtailing individual rights,16 they are an effective vehicle to circumvent otherwise limited federal power. The government uses the tax code to creative incentives for a number of personal choices that cannot be mandated directly, such as marriage, energy-efficient car and home purchases, charitable giving, and saving for retirement. 

The excise tax, in particular, can be a powerful tool to shape social policy. Typically a tax on specific goods,17 the federal excise tax has been a favored way to raise revenue and/or discourage the purchase of specific kinds of items since the Court first upheld an excise tax levied on carriages—then a luxury vehicle—in 1796.18 The reach of excise taxes now extends beyond (modern) luxury automobiles to alcohol, gasoline, tires, airline tickets, coal, and insurance policies issued by foreign companies, among other items.19 A carefully crafted excise tax on guns could similarly reduce the stockpiling of weapons by gun owners and encourage them to purchase safer guns.20

Currently, manufacturers pay a federal excise tax of 10% on handguns and 11% on long guns, some or all of which is passed onto the consumer in the price paid for the weapon.21 No case has yet challenged the firearms excise tax on Second Amendment grounds,22 although a First Amendment case in 1983, Minneapolis Star and Tribune Co. v. Minnesota Commissioner of Revenue, reviewed the constitutionality of a tax singling out the press.23 In that case, the Court held that a use tax24 on paper and ink products consumed in publications, which affected a small number of newspapers, created an unconstitutional burden on the papers’ First Amendment rights.25 In establishing the right to bear arms as a fundamental right, Heller has opened the door for courts to potentially examine similar taxes under heightened scrutiny;26 despite the wide latitude the government enjoys in exercising its taxing power, this power might be more limited in the context of the individual rights articulated in Heller

Even so, taxes do not interfere with Second Amendment rights in the same way they do with First Amendment rights.27 This is because speech begets more speech, and in order to fully exercise this right it must be presumptively unlimited. By contrast, the Second Amendment right articulated in Heller is inherently limited to what is necessary to achieve the specific goal of self defense; effectively exercising this right—against an intruder in the home, for example—requires, and is only physically possible, using one gun. In this sense, guns are more like cars: having many of them might offer a variety of ways to reach an objective, but no matter how many an individual owns, ultimately only one is necessary and sufficient. Thus, to the extent that an excise tax might be vulnerable to a Second Amendment challenge, this claim can be avoided by waiving the tax for the first gun purchase an individual makes. Since the right to self defense is fully secured with at least one weapon (with potentially unlimited ammunition28), exempting the first gun from the tax would leave an individual’s Second Amendment right unencumbered and would allow taxes on additional gun purchases to pass constitutional muster.

Limiting Arsenals with an Incremental Excise Tax on Guns

Only 20.8% of individuals in the United States reported owning a gun in 2010, representing a 32% decline in personal gun ownership since 1985.29 This parallels a similar trend in household gun ownership, which has declined 40% over the last four decades.30 Nevertheless, more guns are concentrated in fewer hands, with an estimated 57 million adults owning 283 million firearms.31 About half of all gun owners own four or more weapons, with the latter group owning an average of twelve guns per person;32 the top 3% of gun owners own twenty-five or more.33 Even when the individual outliers owning the most guns are removed from the calculation, gun owners overall own an average of five weapons per person.34 The distribution of firearms among owners suggests that the current flat excise tax35 does not financially deter individuals from creating personal arsenals.36

In order to reduce the gun stockpiles and curb their role in facilitating criminal activity, the excise tax needs to be structured differently. Specifically, an excise tax designed to limit the accumulation of weapons by a single individual would increase with each additional gun purchased after the first, which would be tax-free. Thus, for example, the tax on successive firearm purchases by the same person might increase by 10% per weapon, so that by the sixth weapon the purchaser would pay half the value of the weapon in taxes. The tax would not prevent individuals from owning as many guns as they like, but would make the choice to create an arsenal significantly more expensive.37

Raising the flat excise tax could similarly reduce the number of weapons purchased but would not distribute the costs created by arsenals among gun owners as accurately. This is because while any gun owner potentially poses a risk to public safety simply by owning a gun—which has some likelihood of ending up in the hands of unauthorized users through theft or burglary—gun owners who own more firearms contribute to this risk at a higher rate by potentially introducing more weapons at a time to the pipeline of stolen guns.38 Further, as noted above, with each additional weapon an owner moves farther from the goal of self-defense and closer to luxury or convenience. An incremental tax is therefore progressive, making the cost of owning additional weapons proportional to the risks they pose and the means of each owner.

Implementing an Incremental Excise Tax

Under the current system, in which private gun sales are unregulated (the so-called “gun show loophole”), tracking the number of guns a person owns would not be feasible. However, if universal background checks were required for all gun sales—a proposal with widespread political support—then tracking gun ownership would be feasible, because there would be an official monitor at the point of every initial sale or transfer.39 Each background check could be supplemented with a requirement of a certificate of title, similar to those used with vehicles and houses, which would be issued to the initial buyer and transferred to subsequent owners. A title would be required only for those weapons most likely to be stolen and used in crime—handguns and semi-automatic rifles and shotguns40 —allowing for the tax to be targeted to those firearms that pose the greatest public safety risk and leaving owners free to purchase recreational and low-caliber weapons without being subject to the incremental tax. A title system could be incorporated into the existing regulatory infrastructure,41 so the government could log the number of guns bought and sold between individuals, and track the number of taxable weapons owned by an individual at a given time.

Because a title would be issued and used only to assess the correct amount of tax for any purchase, it would not impact or restrict an individual’s eligibility to own a weapon and therefore avoid Second Amendment concerns.42 In this regard, a title requirement is far less onerous and intrusive than the licensing and registration requirements already in place for certain kinds of weapons at the federal and state levels.43


The gun control legislation passed since the Sandy Hook shootings has largely addressed the kinds of weapons that may be sold or who may purchase them. But a larger problem highlighted by shootings has to do with the accumulation of weapons by individuals who are legally entitled to own them. As the Sandy Hook tragedy illustrates, arsenals like the one owned by Nancy Lanza create a significant public safety risk by making available a large number of weapons to people unauthorized to use them. The continued stockpiling of guns by a subset of gun owners directly and indirectly exposes weapons to individuals to whom they do not belong. 

Given the murky constitutional landscape after Heller, an incremental excise tax allows the federal government to reduce the risks posed by arsenals while sidestepping a thorny civil liberties issue. A tax on successive gun purchases makes the choice to own a personal arsenal more expensive in proportion to the social costs imposed by the gun owner. Using the tax code to limit arsenals offers the possibility to influence this choice while preserving individual freedom.

  • 41. BATFE already operates a National Tracing Center, which monitors the movement of guns including multiple guns sold to the same purchaser.  Since BATFE would be the enforcement entity for the excise tax, expanding the existing databases at the National Tracing Center would not require much additional infrastructure, and would also supplement efforts by the agency to detect the pattern of stolen and trafficked guns.  See Fact Sheet: National Tracing Center, Bureau of Alcohol, Tobacco, Firearms and Explosives (Feb. 2013),….
  • 42. Another option to avoid Second Amendment concerns would be to waive the incremental excise tax, as well as the title requirement, for guns that contain safety features, such as “smart gun” technology, which make guns less amenable to criminal activity.  These safety features could include biometric trigger locks, which use sensors to read an individual’s fingerprint, allowing only the registered owner of a weapon to use it; a stolen weapon with this feature would be unusable by a criminal and could prevent an incident like Newtown. Another could be microstamping (also known as ballistic imprinting), which allows law enforcement to immediately trace the weapon used in a crime based on just the cartridge, making it less appealing to criminals. A safety exception provision would not only allow gun owners an avenue through which to opt out of both the tax and additional government oversight, but would also further reduce the risks created by arsenals by encouraging gun enthusiasts to purchase safer guns. This kind of shift occurred with tax incentives in the car industry, which increased sales of then-nascent hybrid cars by 5% between 2000 and 2006.  See Kelly Sims Gallagher & Erich Muehlegger, Giving Green to Get Green: Incentives and Consumer Adoption of Hybrid Vehicle Technology 61 J. Environ. Econ. Manage. 1, 7 (2010), available at… The tax incentives for hybrid vehicles typically involved income tax deductions which could be taken on an income tax return; since an excise tax is incurred at the point of sale, the savings would be realized immediately and likely have an even greater impact on consumer behavior, particularly on those who want to own numerous guns and would otherwise be subject to increasing tax rates.
  • 43. See, e.g., 26 U.S.C. § 5841 (2006) (outlining registration requirements for specific weapons); N.Y. Penal Law § 400 (McKinney 2013) (outlining state firearms licensing requirements).  At the same time, a title requirement could easily be incorporated into more stringent licensing and registration requirements if they already exist or are enacted.
