No, you don’t have to use your credit card every month, and no federal law requires it. But letting a card sit completely idle has consequences worth knowing about. Under federal regulation, your issuer can close the account after as few as three consecutive months of inactivity, and that closure can pull your credit score down by shrinking your available credit and, over time, your credit history.
How Long a Card Can Sit Unused
Regulation Z sets the outer limit. A creditor cannot close your account just because you pay in full every month and never owe a finance charge, but the same rule allows a creditor to close any account that has been inactive for three or more consecutive months, as long as no credit has been extended through a purchase, cash advance, or balance transfer, and there is no outstanding balance.1eCFR. 12 CFR 1026.11 – Treatment of Credit Balances; Account Termination
In practice, most issuers wait longer than the minimum, typically six to twelve months of zero activity, before closing a dormant account. Banks treat unused credit lines as a drag on the balance sheet because they must hold capital reserves against each open line. When a card produces no interest revenue and carries ongoing risk, closing it frees up those resources.
Don’t expect a heads-up. Regulation Z exempts account termination from the 45-day advance written notice that applies to other significant changes in account terms.2eCFR. 12 CFR 1026.9 – Subsequent Disclosure Requirements You may find out the account is closed only when you try to use the card.
What Closure Does to Your Credit Score
Two things happen when an issuer closes a card you weren’t using: your utilization ratio can jump, and your credit history eventually shortens.
Utilization Goes Up
Your utilization ratio, the share of available credit you’re currently using across all cards, makes up roughly 30 percent of a standard FICO score.3myFICO. What’s in Your FICO Scores An unused card with a $5,000 limit adds $5,000 of available credit without adding any debt. Close it, and that cushion disappears. Whatever balances you carry on other cards now take up a larger slice of a smaller total.
Credit History Shrinks Later
The age of your accounts is about 15 percent of your FICO score, factoring in the oldest account, the newest, and the average across all of them.3myFICO. What’s in Your FICO Scores A closed account in good standing stays on your credit report for up to ten years, and during that stretch it still counts toward your average account age. The real hit lands later, when the closed account drops off the report entirely and your average age falls with it.
A Permanent $0 Balance Isn’t Ideal Either
Keeping every card at zero sounds safe, but a card that never reports any activity generates no payment history, and payment history is the largest single factor in your score at 35 percent.3myFICO. What’s in Your FICO Scores People with the highest FICO scores generally keep utilization below 10 percent rather than at zero, using their cards lightly and paying them off each cycle.
No Inactivity Fees
Your issuer can close a dormant card, but it cannot charge you for leaving it alone. Federal rules prohibit card issuers from imposing a fee for any violation with no dollar amount attached, and the regulation specifically lists account inactivity as one of those violations. The same rule bars fees for closing or terminating an account.4eCFR. 12 CFR 1026.52 – Limitations on Fees A card that sits in a drawer for a year won’t produce a “dormancy fee” or “non-use charge” on your statement.
Rewards and Credit Balances You Could Lose
Rewards points and miles follow your cardholder agreement, not federal banking law. Many agreements require you to earn or redeem at least one point within a set window, often 12 to 24 months, to keep your rewards balance alive. If the card is closed for inactivity, the accumulated rewards typically vanish with it. The CFPB has said issuers may violate federal law when they cancel rewards consumers have already earned based on buried or vague contract terms.5Consumer Financial Protection Bureau.

Money can go the other direction too. If your issuer owes you a credit balance from an overpayment, a returned purchase, or a duplicate refund, and the account goes quiet, that money can eventually become the state’s property. Federal regulation requires card issuers to make a good-faith effort to refund a credit balance greater than one dollar after it has sat for more than six months.1eCFR. 12 CFR 1026.11 – Treatment of Credit Balances; Account Termination If the issuer can’t reach you, every state’s unclaimed-property law eventually requires the money to be turned over to the state, typically after three to five years. You can still claim it later through the state’s unclaimed-property office, but it takes work.
Simple Ways to Keep a Card Active
You don’t need to overhaul your spending. A single small transaction every few months is enough to keep most issuers from flagging an account as inactive. The easiest approach: assign each idle card a low-cost recurring charge, like a streaming subscription, a cloud-storage plan, or a monthly utility bill, and set up autopay so the balance clears each cycle. That creates a steady trickle of activity, generates positive payment history, and keeps utilization in the single digits.
If a subscription isn’t your style, one intentional purchase per quarter usually does the job. A tank of gas, a grocery run, or a single cup of coffee resets the clock. Set a calendar reminder so the card doesn’t slip out of mind for months.
Reopening a Card That’s Already Been Closed
If your card has already been closed for inactivity, you may be able to reopen it, but the window is narrow. Several major issuers allow reinstatement only within about 30 days of the closure date. After that, you’ll generally need to submit a fresh application, which triggers a hard inquiry on your credit report and offers no guarantee you’ll get the same credit limit or terms.
To ask for reinstatement, call the number on the back of the card or the issuer’s general customer service line as soon as you notice the closure. Some issuers reopen the account on the spot; others run a new credit check first. If you’re past the window or the issuer declines, you’re starting over. Keeping the card lightly active from the beginning is far easier than trying to bring it back.
