15 Common Credit Score Myths — Debunked (2026)
Bad credit advice is expensive. Carrying a balance for 'points,' closing old cards to 'clean up' your file, or paying a company to 'delete' accurate items can each cost you hundreds of points and thousands of dollars. Here are the 15 credit score myths we hear most often at MyITINCredit — with the actual FICO and FCRA rules behind them.

Why credit myths cost real money
The average American loses $50,000+ in extra interest over a lifetime because of two persistent myths: that carrying a balance builds credit, and that closing old cards helps. Neither is true — and both are baked into how millions of people manage their money. This page walks through every myth we see, ranked by how expensive it is to believe.
Myth #1 — "You need to carry a balance to build credit."
False. FICO scores your reported utilization and payment history. As long as your card reports activity to the bureaus each cycle and you pay on time, it builds credit — whether you pay the full statement balance or carry it. Carrying a balance just donates interest to the issuer. See myFICO — how credit scores are calculated.
Myth #2 — "Checking my score will hurt it."
False. A consumer-initiated check is a soft pull and is invisible to FICO and VantageScore models. You can check your score every day of the year with zero damage. Only hard pulls initiated by a lender when you apply for credit affect your score.
Myth #3 — "Closing a credit card raises my score."
Usually the opposite. Closing a card removes its credit limit from your utilization calculation and, over time, drops it from your average age of accounts. Expect a 5–25 point drop, more if it was your oldest card. Keep old cards open with a small autopay charge.
Myth #4 — "ITIN holders can't build credit."
False. Both FICO and VantageScore build files on ITIN holders exactly as they do for SSN holders. The CFPB confirms that lenders can and do extend credit without an SSN. See our ITIN credit score guide for the full process.
Myth #5 — "My income is part of my credit score."
False. Income is not on your credit report. FICO and VantageScore never see it. Lenders see income only when you list it on an application, and they use it for debt-to-income ratios — not credit scoring.
Myth #6 — "All three bureaus show the same score."
False. Equifax, Experian, and TransUnion each hold slightly different data — not every creditor reports to all three. Your FICO 8 can differ by 20–50 points across bureaus. Mortgage lenders typically pull the middle score of the three.
Myth #7 — "Paying off a collection deletes it."
False. Under FCRA §605, a paid collection can legally stay on your report for 7 years from the original delinquency date. Newer models (FICO 9, VantageScore 3.0+) ignore paid collections; older FICO 8 (used by most mortgage lenders) still counts them.

Myth #8 — "Debit and prepaid cards build credit."
False. Neither extends credit — no tradeline is reported. Only credit cards (secured or unsecured), installment loans, and rent-reporting services build credit history.
Myth #9 — "Too many cards will hurt me."
Mostly false. Card count has almost no direct scoring impact. 800+ FICO holders average 5–7 open cards. What matters is utilization, on-time history, and average age of accounts.
Myth #10 — "Marriage merges our credit scores."
False. Every person has their own file for life. Only joint accounts appear on both spouses' reports — and only from the account opening date forward.
Myth #11 — "Credit repair companies can delete accurate items."
False and often illegal. The FCRA protects accurate, verifiable information for 7–10 years. Legitimate services can only dispute inaccurate items — something you can do free at annualcreditreport.com.
Myth #12 — "30% utilization is the sweet spot."
False. 30% is the ceiling, not the target. The highest FICO scores keep reported utilization under 10%, with at least one card between 1–9%. Zero on every card slightly underperforms 1–9% on one.
Myth #13 — "Age, gender, or nationality change my score."
False and illegal. Under the Equal Credit Opportunity Act (ECOA), credit scoring models cannot use age, race, national origin, sex, marital status, or religion. Only credit-file behavior counts.
Myth #14 — "Paying off a loan early hurts my credit long-term."
False. Closing an installment loan may drop your score 5–20 points briefly (credit mix), but the entire on-time payment history stays on your report for 10 years. Never pay interest just to protect a score.
Myth #15 — "One late payment ruins your credit forever."
False. A first 30-day late costs 60–110 FICO points, but the drop fades quickly — most files recover to within 20 points of the pre-late score within 12–18 months if no other negatives are added. The mark itself ages off in 7 years.
Credit myths ranked by cost
| Myth | What it costs | The rule |
|---|---|---|
| Carry a balance to build credit | $300–$1,200/yr interest | FICO scores reported utilization, not interest |
| Close old card to "clean up" | 5–25 pts + age loss | Utilization and account age drop |
| Pay to "delete" accurate items | $79–$149/mo, no result | FCRA §605 protects legal reporting |
| 30% is the target | 30–60 pts left on table | Under 10% is the FICO sweet spot |
| Debit builds credit | All progress lost | No tradeline reported |
| ITIN holders can't build credit | Years of missed history | CRRG allows ITIN + DOB + address match |

Credit score myths — FAQ
Does checking my own credit score hurt it?
No. Checking your own credit is a soft inquiry and never affects your FICO or VantageScore — no matter how many times per day you look. Only lender-initiated hard pulls count against you.
Do I have to carry a balance to build credit?
No — this is the single most expensive credit myth. You build credit by having accounts report on-time activity, not by paying interest. Paying your statement balance in full every month builds credit exactly the same and costs $0 in interest.
Do ITIN holders have credit scores?
Yes. FICO and VantageScore both build files on ITIN holders once tradelines report. The Credit Reporting Resource Guide requires bureaus to use ITIN, DOB, and address rather than SSN when no SSN exists. Your score is built the same way as any SSN holder.
Do all three credit bureaus show the same score?
No. Equifax, Experian, and TransUnion each hold slightly different data because not every creditor reports to all three. Your FICO 8 score can differ by 20–50 points across bureaus, and lenders often pull only one.
Does closing a credit card help my score?
Almost always the opposite. Closing a card removes its credit limit (raising your utilization ratio) and eventually drops the account from your average age of accounts. Keep old cards open with a small recurring charge and autopay.
Will paying off a collection remove it from my report?
Not automatically. Under FCRA §605, a paid collection can legally stay on your report for 7 years from the original delinquency. FICO 9 and VantageScore 3.0+ ignore paid collections, but older FICO 8 (still used by most mortgage lenders) still counts them.
Does my income affect my credit score?
No. Income is not on your credit report and not used by any FICO or VantageScore model. Lenders see income only when you list it on an application. Your score is built entirely from payment history, balances, age, mix, and inquiries.
Do debit cards build credit?
No. Debit cards pull directly from your checking account — no borrowing happens, so no tradeline is reported. Only credit cards, loans, and rent-reporting services build credit history.
Does having 'too many' credit cards hurt my score?
The number of cards itself has almost no direct impact. What matters is total utilization, on-time history, and average age of accounts. Cardholders with 800+ scores average 5–7 open cards.
Will marriage merge my credit score with my spouse's?
No. Every person has their own credit file. Marriage does not combine, average, or share scores. Only joint accounts show on both files — and only from the date the account is opened.
Does paying off a loan early hurt my credit?
Slightly, and only briefly. Closing an installment loan can drop your credit mix and lower your score by 5–20 points, but the long payment history stays on your report for 10 years. Never carry a loan for score reasons — the interest costs far more.
Do prepaid cards build credit?
No. Prepaid cards do not extend credit and are not reported to Equifax, Experian, or TransUnion. Only true credit cards — secured or unsecured — report tradelines.
Can I 'repair' my credit by paying a company to remove accurate items?
No legitimate service can remove accurate, verifiable information — the FCRA protects legally reported items for 7–10 years. Credit repair companies can only dispute inaccurate items, which you can do free at annualcreditreport.com.
Does 30% utilization guarantee a good score?
30% is a ceiling, not a target. The highest FICO scores keep reported utilization under 10%, and one card at 1–9% typically outperforms every card at 0%. Under 30% avoids penalty; under 10% earns the boost.
Does age or nationality affect credit scores?
No. FICO and VantageScore are legally prohibited under ECOA from using age, race, national origin, sex, marital status, or religion. Only credit-file behavior — payments, balances, age of accounts, mix, and inquiries — is scored.
