Cosigning puts your credit at risk even if you never miss a payment
When you cosign a loan, you are legally responsible for the full debt if the primary borrower stops paying. That responsibility shows up on your credit report immediately — the loan appears as an account you owe, even though someone else borrowed the money. Your credit score drops because lenders see you as carrying additional debt, which lowers your debt-to-income ratio and makes you look riskier to other creditors.
The damage happens whether the primary borrower pays on time or not. If they pay perfectly, your score still falls because the loan is listed as your obligation. If they miss payments, your score falls further — and the missed payments stay on your report for seven years. You cannot remove them even if you later pay the debt off, because the payment history is part of your permanent credit record.
The size of the score drop depends on your current credit profile. Someone with excellent credit (750+) may lose 50 to 100 points. Someone with fair credit (650–700) may lose 20 to 50 points. The drop is steeper if the loan is large relative to your income, or if you already carry significant debt.
Key Takeaways
- Cosigning a loan appears on your credit report as debt you owe, lowering your score even if the primary borrower never misses a payment.
- If the primary borrower misses payments, those missed payments damage your credit for seven years and you remain legally liable for the full amount.
- Your debt-to-income ratio worsens when you cosign, which can disqualify you from mortgages, car loans, or credit cards you apply for while cosigning.
- Removing yourself as a cosigner requires the primary borrower to refinance the loan in their name alone, which they can only do if their credit has improved enough to may have access to.
- The credit damage is temporary if the loan is paid off on time — your score recovers within months to a year after the account closes.
How the loan appears on your credit report
The loan shows up as an open account in your credit file the moment the primary borrower signs the paperwork. Credit bureaus (Equifax, Experian, and TransUnion) receive the account information from the lender, and they list you as a cosigner or co-obligor. This means the debt counts toward your total outstanding balance when lenders calculate your debt-to-income ratio.
Your payment history on the account is separate from the primary borrower's. If they pay on time and you do nothing, the on-time payment helps both of your credit scores. If they miss a payment, the missed payment damages both of your scores equally. You have no control over whether the payment is made — you can only be held liable if it is not.
The account remains on your report for the full life of the loan, plus seven years after it closes. If the loan is a 30-year mortgage, your credit report will show that debt for 37 years. If the primary borrower defaults and the lender writes off the debt, the charge-off stays on your report for seven years from the date of default.
When cosigning affects your ability to borrow
Lenders pull your credit report and see the cosigned loan as debt you are responsible for. When you apply for a mortgage, car loan, or credit card, they add that loan payment to your existing debts and divide by your monthly income. If the cosigned loan payment pushes your debt-to-income ratio above their threshold (usually 43 percent for mortgages, 50 percent for auto loans), your application is denied or you are offered a higher interest rate.
This can happen even if the primary borrower has never missed a payment. A lender does not care whether you are actually making the payments — they care that you are legally obligated to make them. A $300 monthly cosigned car loan can cost you tens of thousands of dollars in higher mortgage rates or disqualify you from a home purchase entirely.
The impact is worst if you are planning to borrow within the next few years. If you cosign today and apply for a mortgage in six months, the cosigned loan will still be on your report and will still count against you. The only way to remove it before the loan is paid off is to have the primary borrower refinance it in their name alone.
What happens if the primary borrower defaults
If the primary borrower stops paying, the lender contacts you. You are now responsible for the full balance, not just future payments. The lender can sue you, garnish your wages, or place a lien on your property — the same remedies they would use against the primary borrower. You have no legal defense based on the fact that you did not receive the money.
The missed payments appear on your credit report as late payments, starting 30 days after the first missed payment. After 90 days of non-payment, the account is typically charged off, meaning the lender writes it off as a loss and may sell the debt to a collection agency. The charge-off and any collection activity stay on your report for seven years.
Your credit score can drop 100 to 150 points or more when a cosigned account goes into default. If you have fair credit to begin with, this can push you below 600, making it nearly impossible to borrow money, rent an apartment, or get approved for a credit card. Some employers and insurance companies also check credit scores, so a default can affect your job prospects or insurance rates.
How to remove yourself as a cosigner
The only permanent way to remove yourself is to have the primary borrower refinance the loan in their name alone. This means they apply for a new loan by themselves, use the proceeds to pay off the original loan, and you are released from liability. The new loan appears on their credit report, and the old loan (with you as cosigner) closes.
The primary borrower can only refinance if their credit score and income have improved enough to may have access to on their own. If they still cannot may have access to, the lender will not refinance. Some lenders offer a cosigner release option after a certain number of on-time payments (usually 24 to 36 months), but this is rare and requires the primary borrower to meet income and credit thresholds.
If the primary borrower refuses to refinance or cannot may have access to, you are stuck. You cannot force them to refinance, and you cannot unilaterally remove yourself from the loan. Your only option is to pay off the loan yourself, which defeats the purpose of cosigning in the first place.
How long the damage lasts on your credit
If the loan is paid off on time, your credit score begins to recover as soon as the account closes. The account stops counting toward your debt-to-income ratio immediately, and your score typically rebounds within 3 to 12 months. The closed account remains on your report for 10 years, but it has less impact on your score as it ages.
If there are missed payments, the damage lasts longer. Each missed payment stays on your report for seven years from the date it was first reported as late. A single 30-day late payment has less impact than a 90-day late or a charge-off, but all of them drag down your score for the full seven years. After seven years, the account and all late payments fall off your report automatically.
A charge-off or collection account also stays for seven years, but the impact on your score weakens over time. A charge-off from five years ago hurts less than a charge-off from last month. However, if the debt is sold to a collection agency and they sue you, a judgment can remain on your report for longer depending on your state's laws.
Alternatives to cosigning
If someone asks you to cosign, consider whether there are other ways to help. You could lend them money directly instead of cosigning a loan — this keeps the debt off your credit report and gives you a clear repayment agreement. You could help them improve their credit score first by waiting a few months while they pay down existing debt or dispute errors on their report.
You could also help them find a lender that does not require a cosigner. Some credit unions, online lenders, and subprime lenders work with borrowers who have poor credit or no credit history. The interest rate will be higher, but the primary borrower builds their own credit history instead of relying on yours.
If the person asking is a family member or close friend, be honest about the risk. Explain that you are taking on legal liability for their debt, that it will lower your credit score, and that it could affect your ability to borrow. Many cosigning relationships end in conflict when the primary borrower defaults or stops paying, and the cosigner is left holding the debt.
Frequently Asked Questions
Does cosigning hurt my credit score right away?
Yes. Your score drops the moment the lender reports the account to the credit bureaus, which is usually within 30 days of the loan closing. The drop happens even if the primary borrower makes the first payment on time.
Can I cosign a loan and then remove myself later?
Only if the primary borrower refinances the loan in their name alone. This requires them to may have access to on their own credit and income. If they cannot may have access to, you remain liable for the full debt. Some lenders offer cosigner release after 24 to 36 on-time payments, but this is uncommon.
What if the primary borrower pays on time — does cosigning still hurt me?
Yes. The loan counts as your debt for the purpose of calculating your debt-to-income ratio, which can disqualify you from other loans or force you to pay higher interest rates. Your score also drops because lenders see you as carrying more debt, even though you are not making the payments.
How long does it take for my credit to recover after the loan is paid off?
If there are no missed payments, your score typically recovers within 3 to 12 months after the account closes. The closed account stays on your report for 10 years but has less impact as it ages. If there were missed payments, they stay on your report for seven years from the date they were first reported as late.
Can I be sued if the primary borrower defaults?
Yes. The lender can sue you for the full balance, garnish your wages, or place a lien on your property. You have no legal defense based on the fact that you did not receive the money or did not authorize the spending. You are equally liable as the primary borrower.
