The regulator's concern points the opposite way from the folk framing. The received story is that churning is a consumer trick and the issuer's rules are the defense against it. The Bureau's guidance on rewards programs frames the undisclosed rule as the potential problem. Among its illustrative examples of potentially unfair rewards practices, it lists: "Promotional 'sign-up' offers that are denied based on hidden conditions that consumers were not reasonably aware of, such as 'churning' conditions that restrict how frequently a consumer can earn sign-up rewards, time periods to earn rewards that are effectively shortened by the hidden and unavoidable period of time needed to receive and activate a card, or promotional offers that are unavailable for applicants through certain channels."
The same document goes further on the discretion involved: "consumer complaints indicate rewards program operators may interpret as impermissible 'gaming' or 'churning' consumer card usage behaviors that are otherwise permissible under cardholder agreements and satisfy objective sign-up promotion criteria, such as closing an account after spending the required amount for a promotional rewards bonus." This is guidance to enforcers about how existing prohibitions on unfair and deceptive acts or practices apply, and its verbs are hedged accordingly: operators "risk committing" such practices, conduct "may be" unfair. Nothing in it makes any particular program term unlawful, and nothing in it entitles a cardholder to a bonus.
Why issuers restrict it, in the Bureau's own words, which is the most useful paragraph on this page. From the Issue Spotlight: "Issuers create policies that limit crediting rewards to consumers whose behavior matches activity they deem as 'gaming' or 'abuse' to protect their average profitability per account; however, this activity is rarely clearly defined. Banks typically amortize the cost of up-front promotional bonuses over a multi-year period, where the additional interchange, interest, and fee revenue from a given account offset the initial rewards expense. If a card is only opened to earn that lump sum and then is immediately closed, the bank likely loses money on the cardholder and would want to limit future expenses associated with that consumer."
That is the whole economic logic of the practice from both sides. A sign-up bonus is a customer-acquisition cost the issuer expects to recover over years. A cardholder who takes the bonus and leaves has extracted the acquisition cost without supplying the years, and every rule an issuer writes about eligibility is an attempt to price that in.
The rules themselves are unilateral and frequently unpublished, which is the practical difficulty. Issuers do apply limits on how often a bonus can be earned, on how recently other accounts were opened, and on whether a bonus is available at all on a card previously held. Those limits are set by each issuer, can change without notice, and are often not stated in the promotional material. The Bureau's phrasing, "rarely clearly defined," is the accurate description. The consequence for a reader is unglamorous: the only rule that binds them is the one written in their own cardholder and rewards program agreement, and the numbers circulated in online communities describe what people have observed rather than what any issuer has undertaken.
The clawback pattern, attributed carefully. The Issue Spotlight records that "in the case of at least one issuer, consumers reported being required to pay back previously redeemed rewards value after they closed their account within a certain period of time," and quotes a complaint describing a requirement to keep the account open for twelve months that the consumer found only in the fine print rather than in the marketing letter. These are consumer complaints as reported by the Bureau, not agency findings and not a description of any general market practice, and that distinction matters: a complaint records what someone experienced and asserts, and it is evidence of the pattern's existence rather than of its prevalence.
What actually protects a reader here. Two provisions of Regulation Z do real work and neither is about rewards. Total required fees in the first year after opening cannot exceed 25 percent of the opening credit limit, which limits how expensive a bonus-chasing application can be to obtain. And an increase in an annual fee is a significant change in account terms, with 45 days' notice and generally a right to reject it. Both are the annual fee page's territory and both are worth knowing before opening an account intended to be short-lived.
The honest cost side, and it is mostly not the score. Three costs are real and one is overstated. The overstated one is score damage: the effect of an application inquiry is small for most people, and the durable mechanisms are average account age and the new-credit factor, both of which are minority inputs to a score. The real costs are an annual fee that renews on a card no longer being used, spending induced by a minimum-spend requirement that would not otherwise have happened, and the attention the practice requires, since every element of it, the enrollment, the spending window, the redemption and the closing decision, is a deadline that has to be met by somebody. That last one is why the practice suits a particular temperament and quietly punishes everyone else: the returns are concentrated in the bonuses, and the bonuses are contingent on not forgetting.
On tax, one clause suffices: a bonus earned by spending is generally treated the way any spending-linked reward is treated, while a bonus paid without a spending requirement is a different transaction. The analysis, including the single Tax Court decision that addresses manufactured spending directly, belongs with credit card rewards.
