“Flat Tax or Flat Taxpayer?” is a short polemical economic essay on the U.S. Treasury’s 1986 draft tax plan and the academic celebration of a flatter income tax. Rothbard’s central thesis is that the advertised simplicity of the flat tax is a political trap: simplification would come by abolishing deductions, allowances, and distinctions that let people retain income and capital, so the reform threatens to flatten taxpayers rather than free them.
This near-unanimity should not be surprising, because a flat tax appeals to the sort of academic who, regardless of ideology, likes to push people around like pawns on a chessboard.
Rothbard opens by making consensus itself suspicious. Cross-ideological enthusiasm is not proof of neutral rationality but evidence of a shared technocratic habit, the attraction of a clean scheme that makes taxpayers administratively manageable. His decisive conceptual move is to invert the usual meaning of tax complexity. For him, the code is complicated because households, firms, and industries have struggled to escape the income tax. Deductions and exclusions may be untidy, but they are also defensive shelters against confiscation.
And these people have already found out what our flat-tax academics seem not to have cottoned to: there are things in this life worse than complexity, and one of them is paying more taxes. Complexity is good if it allows you to keep more of your own money.
The middle of the essay tests the slogan of simplicity against the plan’s practical consequences. Rothbard argues that taxing capital gains like income would weaken saving and entrepreneurial investment, ending accelerated depreciation would hurt capital-intensive industry, restricting mortgage deductions and taxing “imputed” rent would punish homeowners, and removing depletion, casualty, and medical deductions would convert real capital loss or misfortune into taxable capacity.
RAISE the tax on capital gains to treat it like income, thereby crippling saving and investment, particularly in new and growing firms.
His example of imputed rent shows both the comic and theoretical edge of the essay. Tax reformers can invent a noncash income stream for homeowners, but taxpayers cannot satisfy tax claims with an equally fictional payment.
Unfortunately, those who are taxed on "imputed" income will not be able to pay their taxes in "imputed" form.
Rothbard’s point is not merely that existing beneficiaries dislike losing privileges. He rejects the idea that allowances for depreciation and depletion are subsidies, because he treats them as mechanisms for avoiding taxes on capital consumption and accumulated wealth. In his framework, fairness-through-symmetry mistakes accounting uniformity for economic justice.
The normative core appears when Rothbard distinguishes his argument from a blanket defense of every status quo advantage. He is willing to impose losses through radical change, but only where the change expands liberty; the flat tax, by contrast, sacrifices people to classification and neatness.
I am willing to advocate radical measures that impose losses on some people, but only to achieve a substantial increase in freedom. But severe losses merely for the sake of symmetry?!
The final section answers the claim that flat taxation would eliminate lawyers and accountants. Simple forms already exist for many taxpayers; others endure complexity because it reduces their liability, while businesses would still need to calculate net gains and losses. Compliance professionals are recast as protective institutions, not mere social waste.
The rest of us who struggle with complex forms are doing so for a good reason: to pay less taxes.
Rothbard’s security metaphor clarifies his broader theory of taxation. Lawyers and accountants resemble locks or fences: costly only because the threat exists, but rational as defenses against seizure.
Similarly, we pay money to the lawyers and accountants because, like fences or locks, they are our defense, our shield and buckler, against the tax man.
The close radicalizes the simplicity argument. If the aim is truly to remove the compliance industry and paperwork, the source of both must be removed; the endpoint is abolitionist rather than technocratic.
Similarly, the way to get rid of tax lawyers and accountants is to abolish the income tax.
The essay’s relevance lies in its challenge to an enduring tax-reform ideal. Rothbard refuses to treat a broad base and lower rates as self-evidently liberating, asking who loses protection when the base is broadened and whether administrative simplicity expands state reach. Brief, satirical, and conceptually sharp, the piece turns “simplicity” from a neutral virtue into an instrument of fiscal power.
