17 credit-card myths, debunked

Credit-card advice has accumulated a lot of folk wisdom that was either never true or stopped being true years ago. Some of it is harmless. Some of it actively costs people money. Here are the most common myths, debunked, with the actual mechanics of how credit cards and credit scores work today.

Myth 1: "Carrying a balance helps your credit"

False. One of the most expensive misconceptions in personal finance.

Credit bureaus see two pieces of monthly data per card: was the payment made on time, and what was the balance at statement close. They don't know whether you paid in full or paid the minimum. Both pay-in-full and pay-in-part are reported identically, "account in good standing."

Carrying a balance just means you're paying interest. Your credit-building outcome is identical to paying in full. The bank loves this myth because it generates billions in interest revenue from people who think they're "helping their credit."

What to do instead: Pay your statement balance in full every month. Set autopay.

Myth 2: "Closing a card you don't use helps your credit"

False, usually. Closing a card hurts your credit in three ways: it raises utilization (lower available credit), it eventually hurts average account age (when the closed account ages off your report after ~10 years), and it ends ongoing positive payment history.

For no-fee cards, the right move is to not use them much rather than close them. Charge a small recurring bill once a year to prevent inactivity-based closure by the issuer.

Myth 3: "Checking your credit score lowers it"

False. When youcheck your own score (via Credit Karma, your bank's app, or an annual free credit report), it's a soft pull. Soft pulls have no effect on your score and aren't even visible to other lenders.

Hard pulls, when you apply for credit, do nick your score, typically by ~5 points each. Those decay over 12 months and fall off entirely after 24.

Myth 4: "You need to pay your card on the due date, not before"

Pay before the statement closing date for utilization reasons, not just before the due date. The bureaus see your balance at statement close, not at payment time. So even if you religiously pay your statement balance on the due date, you're reporting that statement balance as "outstanding" for the next ~30 days.

For lower reported utilization, pay your balance down a few days before statement close, not before the due date.

Myth 5: "0% utilization is best"

Slightly false.0% utilization across all cards actually under-scores you slightly compared to having 1-9% utilization on at least one card. The reason: 0% suggests you're inactive, which is a weaker positive signal than "using credit and paying responsibly."

Aim for 1-9% reported on at least one card. The difference from 0% is small (5-ish points) but real.

Myth 6: "Credit-card rewards are taxable"

False, usually.The IRS treats credit-card rewards as rebates on purchases, not income. They're tax-free. This applies to:

• Cash back on spending
• Welcome bonuses earned by hitting a spending requirement
• Points and miles earned from spending

The exception: bank account bonuses earned with no spending requirement (e.g., open a checking account, get $300) are considered taxable income and get a 1099. Credit-card bonuses with a spending requirement are not.

(This isn't legal or tax advice, talk to a CPA for your specific situation.)

Myth 7: "You should only have one credit card"

False. Having more cards typically helpsyour credit:

• More total available credit = lower utilization for the same spending.
• More accounts in good standing = better credit mix and longer combined history over time.
• Diversification, if one card is compromised, you have backups.

The thing that hurts is opening many cards in a short window (each is a hard pull, drops average account age). Once they're open and aged, more cards is better. The average person with a 800+ credit score has 5-7 active credit cards.

Myth 8: "Co-signing a loan is safer than being an authorized user"

False, generally the opposite.Co-signing a loan makes you legally liable for the debt. If the primary defaults, you're on the hook financially and your credit suffers as if it were your own debt.

Authorized user is much lower risk: you're not legally liable for the debt. Negative information from the primary appears on your report (so you should choose your AU relationships carefully), but you can't be sued for non-payment.

Myth 9: "Premium cards are scams"

False, but with caveats. A premium card pays for itself if you actually use the credits and benefits at their face value. The math frequently works for engaged users.

It failsif you carry the card "for status" without engaging with the credits. The Amex Platinum's $895 fee minus its monthly Resy/streaming/Uber credits costs you real money if you don't fly, don't eat at Resy restaurants, and don't Uber.

Run the actual numbers, see Premium card math.

Myth 10: "Foreign-transaction fees are unavoidable"

False.Most travel cards have no FTX fee, and several no-annual-fee cards too (Capital One Quicksilver, SavorOne, Petal 2). If your card charges 3% on foreign purchases, that's a choice, switch to a no-FTX-fee card before traveling.

See Foreign transaction fees for details.

Myth 11: "Asking for a credit limit increase always involves a hard pull"

False, depends on the issuer. Many issuers will give a soft-pull credit limit increase on request: Discover, Bank of America, Wells Fargo, sometimes Citi. Capital One and Amex generally do hard pulls; Chase varies.

Always ask first: "Will this be a hard or soft pull?"

Myth 12: "Closing a card removes it from your credit report immediately"

False. Closed accounts stay on your credit report for ~10 years (positive accounts) before falling off. Negative accounts (late payments, charge-offs) stay 7 years.

While present, the closed account contributes to your average account age. So closing your oldest card hurts in 10 years when it falls off and your average drops.

Myth 13: "Paying off collections will boost your score"

Partially false.Under newer FICO models (FICO 9, FICO 10) and VantageScore 3.0+, paid collections are ignored, paying them off raises your score. But under older FICO models still used by some lenders (FICO 8), paid collections are still counted. So "paying off collections boosts your score" is true under newer models but not all of them.

Better strategy: negotiate "pay for delete" with the collector, they remove the collection entirely in exchange for payment. Not all collectors agree, but it's worth asking.

Myth 14: "Debit cards build credit"

False.Debit cards aren't reported to credit bureaus at all. They're a payment method drawing on your bank account; no credit is being extended. To build credit, you need a credit product, a credit card, a student/auto/personal loan, etc.

Myth 15: "Newer credit cards are riskier"

False. The risk profile of a credit card has nothing to do with its age. New cards from major issuers (Bilt Blue, Citi Strata Elite, Atmos Ascent) have the same regulatory protections, fraud liability, and reporting requirements as 30-year-old card products.

Myth 16: "You should pay your card down to zero before the statement closes to avoid interest"

Half-true, slightly misleading.You don't need a $0 balance at statement close to avoid interest. As long as you pay your full statement balanceby the due date, you owe zero interest, that's what the grace period is.

Paying down to $0 before statement close is a separate strategy, it lowers your reported utilization, helping your credit score. But it's not required to avoid interest.

Myth 17: "Adding cards to your wallet builds credit"

False. Adding a card builds credit only when:

• The card reports to credit bureaus (most do; Discover doesn't for AUs).
• You make on-time payments.
• You keep utilization low.

A card you opened and never use just sits there. It eventually ages and adds account age, but the on-time payment history is what really moves the needle.

Recap

The pattern across most of these myths: they treat your credit score as a black box you can't understand. It's actually a fairly transparent algorithm. The mechanics are:

• Pay on time, every time.
• Keep utilization low.
• Hold accounts a long time.
• Apply for new credit sparingly.

Everything else is detail. If your strategy follows those four principles, you'll have a top-tier credit score within a few years regardless of which myths you've heard.
