The Consent

The tax reaches a person who may have voted against it, disliked the expenditure, or had no part in choosing the government that imposed it. Calling the payment a contribution does not remove its compulsory character. The question of consent begins at that fact. A private purchase ordinarily permits refusal; a common service often cannot be supplied on terms that let every beneficiary decide afterward whether to pay. Courts, protection against shared hazards, and the administration of public rules require a means of settling obligations among people who disagree. A defensible fiscal order must explain both the need for a common decision and the authority by which that decision binds the person who lost the argument.

The earlier Consent described taxation as a bargain between the governed and those who govern. That bargain is most useful here as a continuing institutional relationship, with obligations on both sides. Those who pay can demand an account of the purposes, the distribution of the burden, and the use of receipts; those who administer can require compliance with publicly established obligations. Representation gives people a route to influence the rule before the payment falls due and to change the rule afterward. It cannot make each payment an individually chosen purchase. Nor does a ballot alone answer every question of fairness. A majority can impose a burden concentrated on a group it does not hear. The fiscal bargain therefore includes the terms on which objections are considered and unequal treatment can be challenged.¹

Unanimous agreement to each expenditure becomes difficult when the service benefits people who can withhold payment without losing its protection. Consider three residents deciding whether to build a shared flood barrier. It costs ninety units and gives each a benefit valued at forty. Contributions of thirty each leave every resident ten better off in this simplified account. Yet if two residents would somehow fund the whole barrier, the third could gain forty by contributing nothing. The temptation to wait for others is built into the arrangement. A general rule for shared payment can solve that problem. Change one resident's benefit to ten, however, and equal shares leave that person twenty worse off. The existence of a collective gain establishes a problem worth solving; its division still calls for a justification.²

Two familiar principles offer different accounts of that division. The benefit principle connects payment to what the public arrangement supplies; the ability-to-pay principle connects it to the resources a person can reasonably contribute. A road used intensively by a commercial fleet invites one comparison, a court protecting everyone's rights another, and assistance to a household without income a third. Many benefits cannot be assigned to individual recipients with the precision of a shop receipt, while some purposes deliberately transfer resources across people. A fiscal order can combine principles, but it must make the combination intelligible. Invoking the common good without identifying who gives and who gains leaves the burden hidden; invoking private entitlement without considering the institutions sustaining it leaves the starting position unexplained.³

Trust can support compliance, while fair administration gives trust something to rest upon. A taxpayer who sees clear rules, usable procedures, and comparable treatment has a different reason to cooperate from one who expects arbitrary demands or impunity for the well connected. OECD research on tax morale finds associations between trust in government and willingness to pay, with meaningful differences across regions and public services. That evidence supports attention to the relationship, without making trust a mechanical product of higher taxation or proving that every efficient collector enjoys consent. Enforcement also matters: an honest payer may reasonably want assurance that others face the same obligation. A system that offers explanation without credible enforcement can ask the conscientious to subsidize the opportunistic; one that offers force without explanation leaves its authority continually contested.⁴

The right to contest a tax is part of the institution that gives its collection a claim to legitimacy. Assessment should be understandable, errors correctable, and the burden open to political revision. These are standards by which a fiscal order can be judged, alongside its purposes and distribution. They do not turn each person's disagreement into a private power to cancel an obligation. Equally, the fact that a government can compel payment supplies evidence of capacity, not a complete moral defense of its demand. The distinction protects both sides of the inquiry. A community needs decisions that bind, and the person bound needs reasons and procedures through which the claim can be answered. Authority has to bear the weight of that reciprocity rather than merely invoke its own existence.⁵

Consent in taxation is therefore larger than approval of a particular bill and more demanding than acquiescence to a collector. It resides in a fiscal order through which people can authorize common purposes, examine the accounts, contest the allocation, and revise the rules while remaining responsible to one another. The argument does not produce a single rightful tax rate. It identifies what any proposed rate must answer: a purpose, a basis of authority, a defensible division, and institutions capable of correction. The next plate follows the distance between the obligation written into that order and the payment actually received. Where rules are uneven, obscure, or readily escaped, the public bargain can be altered without a vote—through the quiet migration of the burden onto those whose receipts are easiest to see.
