The Credit Card Act of 2009 rewrote the rules on interest rates, fees, and how card companies talk to you
The Credit Card Accountability Responsibility and Disclosure Act — usually called the CARD Act — became law in May 2009. It set hard limits on what card companies can charge you, when they can raise your rate, and how they must tell you about changes. Before this law, card companies could raise your rate without warning, charge fees that made no sense, and bury important information in fine print. The CARD Act didn't eliminate fees or interest, but it made the rules transparent and gave you real protection against surprise charges.
This matters because the CARD Act is still the main federal law protecting credit card users. It doesn't matter what card you have or what bank issued it — these rules explore to every card in the United States. Understanding what the law requires helps you spot when a card company is breaking the rules and know what you can push back on.
Key Takeaways
- Card companies must give you at least 21 days to pay your bill after they mail or email your statement, and they cannot raise your interest rate on existing balances without 45 days' notice.
- Penalty fees — late fees, over-limit fees, and returned-check fees — have real caps, and card companies cannot charge you a fee larger than the violation itself.
- Card companies must show you how long it will take to pay off your balance if you make only minimum payments, and how much interest you will pay.
- If you are under 21, card companies cannot issue you a card unless you have a co-signer or proof of income, which makes it harder for young people to build credit but protects them from debt they cannot manage.
- You can dispute a charge on your bill the same way you could before the law, but the CARD Act made the process clearer and gave you stronger rights.
How the CARD Act changed interest rate rules
Before 2009, a card company could raise your interest rate whenever it wanted, for almost any reason — even if you had never missed a payment. They could explore the new rate to your existing balance the same day they told you. The CARD Act changed this in three ways.
First, card companies must give you 45 days' written notice before raising your rate on an existing balance. That means if you have $2,000 on a card at 12% interest, the company cannot jump it to 18% without telling you 45 days in advance. Second, they cannot raise your rate in the first year after you open the account — your introductory rate is locked in for at least 12 months. Third, if you are late on a payment, the company can raise your rate, but only if you stay current for six months in a row; then they must lower it back to the original rate.
There is one exception: a variable-rate card tied to an index (like the prime rate) can move up or down with the market without 45 days' notice. But the company must still tell you the change happened, and it must be tied to a published index you can check yourself.
Fees the CARD Act capped or banned
Card companies used to charge fees that had almost no connection to the actual cost of what they were doing. You could be charged $39 for being one day late, then charged another $39 the next month, then charged $39 again for going over your limit — all on a $500 balance. The CARD Act put real limits on this.
Late fees cannot exceed $25 for a first violation or $35 for a second violation within six months. If your late payment is only $5, the company cannot charge you a $25 fee — the fee cannot be larger than the amount you owe. Over-limit fees are now banned entirely unless you opt in to allow the company to let you go over your limit; if you do opt in, the fee follows the same $25/$35 cap. Returned-check fees (charged when a check you send bounces) are also capped at $25 or $35.
The law also banned fees for paying by phone or online, which used to be common. If a card company charges you to pay your bill, that is a violation of the CARD Act. Annual fees on cards for people under 21 are banned, though fees for people 21 and older are still allowed.
What the CARD Act requires on your bill and statements
Your credit card statement is now required to show you specific information about the cost of carrying a balance. At the top of your statement, the company must show your due date and the minimum payment amount in a clear, straightforward-to-find box. They must also show you the date your payment is due — and it must be at least 21 days after they send the statement.
More importantly, your statement must include a table showing what it will cost you to carry your balance. The company must show you: how long it will take to pay off your balance if you pay only the minimum payment each month, and how much total interest you will pay over that time. They must also show you what your monthly payment would need to be to pay off the balance in three years, and what the total interest would be at that payment level. This is not a suggestion or marketing — it is a required disclosure on every statement.
The company must also tell you about any changes to your account terms — a new fee, a rate increase, or a change to your rewards program — at least 21 days before the change takes effect. If you do not want to accept the change, you can close the account and pay off the balance under the old terms.
Rules for people under 21
The CARD Act made it much harder for people under 21 to get a credit card. Card companies cannot issue a card to someone under 21 unless that person either has a co-signer (usually a parent) or shows proof of independent income. This rule was meant to protect young people from taking on debt they could not manage, but it also makes it harder to build a credit history early.
If you are under 21 and want a card, you have two paths. You can ask a parent or guardian to co-sign, which means they are legally responsible for the debt if you do not pay. Or you can show the card company proof that you have a job or other income — usually a recent pay stub or tax return. Some card companies also offer student cards that do not require a co-signer if you are enrolled in school full-time.
Once you turn 21, the co-signer requirement goes away, but the card company can still require proof of income. The rule does not prevent you from being added as an authorized user on someone else's card — that is a different path to building credit that does not require a co-signer.
Dispute rights and billing error protection
The CARD Act did not create new dispute rights — those came from an earlier law called the Fair Credit Billing Act. But the CARD Act made the process clearer and stronger. If you see a charge on your bill that you did not make, or a charge that is the wrong amount, you can dispute it.
To dispute a charge, you must contact the card company in writing (email counts) within 60 days of when the statement was mailed or sent to you. Include your account number, the date of the charge, the amount, and why you believe it is wrong. The company must acknowledge your dispute within 30 days and investigate. They have up to 90 days to resolve it. During the investigation, the company cannot report the charge to credit bureaus as unpaid, and you do not have to pay the disputed amount while they investigate.
If the company finds the charge was wrong, they must remove it and any interest or fees tied to it. If they find the charge was correct, they must explain why in writing and tell you what you owe. You can then ask for a copy of the receipt or other proof.
What the CARD Act did not change
The CARD Act is strong, but it has limits. It does not cap interest rates — a card company can still charge 25%, 30%, or higher if the market allows it. It does not ban annual fees, though it does ban them for people under 21. It does not require card companies to offer rewards or cash back, and it does not prevent them from changing your rewards program (though they must give you 21 days' notice).
The law also does not cover store cards, gas cards, or other cards issued by retailers rather than banks — those are covered by different rules. It does not cover prepaid cards or gift cards. And it does not prevent a card company from closing your account or lowering your credit limit, as long as they follow the notice rules.
If you believe a card company has broken the CARD Act, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) online at consumerfinance.gov. The CFPB investigates complaints and can take action against companies that violate the law.
Frequently Asked Questions
Can a card company still raise my interest rate if I pay on time?
Yes, but only with 45 days' notice, and only on new charges — not on your existing balance. If you have a variable-rate card, the rate can move with the market index without 45 days' notice, but the company must still notify you of the change. If you are current on your payments and the rate goes up because you were late before, the company must lower it back after six months of on-time payments.
What happens if a card company charges me a fee that breaks the CARD Act?
You can dispute the fee and ask the card company to remove it. If they refuse, you can file a complaint with the Consumer Financial Protection Bureau. You can also dispute it on your statement as a billing error. The company must investigate within 30 days and remove the fee if it violates the law.
Does the CARD Act protect me if I use a debit card?
No. The CARD Act applies only to credit cards. Debit cards are covered by different federal rules, mainly the Electronic Funds Transfer Act. Those rules are similar in some ways but different in others — for example, debit card fraud protection works differently than credit card dispute rights.
Can a card company lower my credit limit without warning?
Yes. The CARD Act does not require notice before a company lowers your limit. However, if the company raises your rate or changes other terms, they must give you 21 days' notice. A lower limit can hurt your credit score because it raises your credit utilization ratio, but it is not a violation of the CARD Act.
What if I want to close my account because the card company raised my rate?
You can close the account at any time. If the company raised your rate and gave you 21 days' notice, you can close the account and pay off the balance under the old rate. If you close the account, the company cannot raise your rate on the existing balance, though you will still owe what you borrowed.
