CARD Act — Credit Card Consumer Protections & Billing Rights

The Credit Card Accountability Responsibility and Disclosure Act of 2009 (CARD Act) (amending the Truth in Lending Act, 15 U.S.C. § 1637) is the most significant federal credit card reform law — enacted to end abusive industry practices that cost consumers billions of dollars annually. Before the CARD Act, credit card issuers could raise your interest rate at any time, for any reason (including "universal default" — raising your rate because you were late on a payment to a different creditor), apply payments to the lowest-rate balance first (maximizing interest charges), charge unlimited late fees, impose over-limit fees without your consent, and change your account terms with minimal notice. The CARD Act prohibited these practices and established a consumer-protective framework: interest rate increases on existing balances are restricted, payments must be applied to the highest-rate balance first, late fees must be reasonable and proportional (the CFPB issued a 2024 rule capping them at $8, but the U.S. District Court for the Northern District of Texas vacated that rule on April 15, 2025 after the Trump-era CFPB joined the trade associations in a consent judgment — late fees are now back to the prior $32 / $41 safe harbors), minimum payment disclosures must show how long it will take to pay off your balance making only minimum payments, and under-21 protections require proof of ability to pay or a cosigner before issuing a card. The CARD Act has saved American consumers an estimated $16 billion per year in fees and interest charges since its enactment. It is enforced by the CFPB (for most issuers) and the OCC, Federal Reserve, and FDIC (for banks under their supervision).

How It Works

The CARD Act imposes strict restrictions on when credit card issuers can raise your rate: for the first 12 months after account opening, promotional or introductory rates cannot be increased (except for variable-rate index changes, the end of a promotional period, or 60+ days delinquency); any rate increase requires 45 days' advance written notice (15 U.S.C. § 1637); and increases generally cannot apply to existing balances — only to new purchases made after the increase takes effect; if your rate was raised due to a 60+ day late payment, the issuer must review it every 6 months and reduce it if warranted. Before the CARD Act, issuers could raise rates retroactively on existing balances without notice. The payment allocation rule (12 C.F.R. § 1026.53) is equally significant: when a cardholder has balances at different interest rates on the same card — a 0% promotional balance and a 22% purchase balance, for instance — any amount above the minimum payment must be applied to the highest-rate balance first, preventing the pre-CARD Act practice of applying payments to the lowest-rate balance to maximize interest charges on high-rate debt.

Late fees must be "reasonable and proportional" to the violation and cannot exceed the minimum payment due; the CFPB's 2024 rule set an $8 safe harbor (down from $32), but the rule was vacated by the U.S. District Court for the Northern District of Texas on April 15, 2025 after the Trump-era CFPB (Acting Director Russell Vought) settled with the industry plaintiffs. The under-21 rule bars issuers from issuing a credit card to anyone under 21 unless the applicant demonstrates an independent ability to repay (documented income or assets) or has a cosigner over 21; credit limit increases for under-21 cardholders require the cosigner's written consent; and free-gift marketing within 1,000 feet of college campuses is prohibited. Billing cycle rules ensure a minimum 21-day grace period from statement date to due date, the same due date each month, and payments received by 5:00 PM on the due date credited that day — with payments due on weekends or holidays treated as on time the next business day.

How It Affects You

If you received a 45-day rate increase notice from your credit card issuer: The CARD Act gives you a meaningful window to act. Rate increases on existing balances are prohibited — the higher rate can only apply to new purchases made after the increase. But the practical play when you receive a rate-increase notice: pay down as much existing balance as possible during the 45-day window at your current lower rate. You also have the right to opt out of the increase and close your account — your issuer must let you pay off the existing balance at the old rate (though your card may be canceled). If you've had a rate increased because you were 60+ days late, the issuer must review every 6 months and reduce the rate if you've made payments on time. Call and ask.

If you carry balances with different interest rates on the same card: The CARD Act's payment allocation rule works in your favor. If you have a 0% balance transfer and a 22% purchase balance on the same card, your payments above the minimum must go to the highest-rate balance first — the 22% purchases. This is a significant improvement from pre-CARD Act rules that let issuers apply payments to the lowest-rate balance to maximize interest charges. Practical implication: avoid using a card with a 0% promotional balance for new purchases, because the payment allocation rule means you're paying down those purchases at 22%+ while the 0% balance sits there accruing nothing — until the 0% period ends and the promotional balance becomes subject to the standard rate.

If you've been hit with a late fee: Current law requires late fees to be "reasonable and proportional" to the violation — they cannot exceed the minimum payment due. The CFPB's 2024 rule set an $8 safe harbor (down from $32), but it was vacated by the Northern District of Texas on April 15, 2025; the prior safe harbor amounts (~$32 for a first violation and ~$41 for a subsequent violation within six billing cycles) remain in effect. Your due date must be the same day each month, and any payment received by 5 PM on the due date must be credited that day. If your due date falls on a Sunday or holiday, a payment received the next business day is on time. Your statement must include a minimum payment warning showing how long it would take to pay off your current balance making only minimum payments — for a $5,000 balance at 22% making $100/month minimums, that calculation is sobering (often 10+ years and $3,000+ in interest).

If you're under 21 trying to build credit: The CARD Act requires issuers to verify your ability to repay before issuing a card. Options: (1) show documented income (part-time job, regular allowance, scholarship payments); (2) have a parent or responsible adult cosign — though note the cosigner is fully liable for the debt; (3) get a secured credit card (deposit-backed, no cosigner required) from a bank or credit union — these report to the credit bureaus and build credit history without requiring a cosigner. A secured card with a $500-$1,000 deposit, used for small purchases and paid in full each month, is the most straightforward path to building credit as a young adult.

State Variations

The CARD Act is federal law that applies uniformly to all credit card issuers:

• State usury laws may set maximum interest rates, but national banks are generally exempt under the National Bank Act (preemption)
• Some states have additional credit card consumer protections beyond federal law
• State attorneys general can enforce CARD Act violations alongside the CFPB
• The CARD Act generally preempts weaker state laws but does not preempt stronger state protections

Implementing Regulations

• 12 CFR Part 1026 — CFPB Regulation Z (Truth in Lending) — the primary implementing regulation for the CARD Act, covering credit card disclosure requirements, billing practices, payment allocation, and penalty fee limits
• 12 CFR Part 1026.52 — Limitations on penalty fees, including the "reasonable and proportional" standard for late fees, over-limit fees, and returned payment fees
• 12 CFR Part 1026.55 — Limitations on increasing annual percentage rates, fees, and charges on existing credit card balances (the core rate-freeze protection)
• 12 CFR Part 1026.9 — Subsequent disclosure requirements, including the 45-day advance notice requirement before rate increases or significant term changes take effect

Pending Legislation

Credit card fee caps and junk fee legislation have been introduced in the 119th Congress. See Consumer Financial Protection for related legislative activity.

Recent Developments

The CFPB's 2024 late fee rule — capping safe harbor late fees at $8 (down from $32) — was the most significant post-CARD Act development. The banking industry challenged the rule in court; following the change in CFPB leadership in early 2025 (Acting Director Russell Vought), the CFPB joined the industry plaintiffs in seeking vacatur, and the U.S. District Court for the Northern District of Texas vacated the rule on April 15, 2025, holding it violated the CARD Act and APA. The safe harbor reverted to ~$32/$41. The Credit Card Competition Act (requiring large issuers to offer at least two processing networks for routing transactions) has bipartisan support but faces industry opposition. The CFPB has also targeted junk fees in credit card billing — including fees for paper statements, inactivity, and account closure. Credit card debt reached record levels (over $1.1 trillion in 2024), making CARD Act protections increasingly important for consumer financial health.
