You can cosign a credit card, but your options are narrow: most major issuers — American Express, Bank of America, Capital One, Chase, Citi, Discover, and Wells Fargo — no longer accept cosigners on credit card applications. The arrangement still exists at some smaller credit unions and regional community banks, and when it does, the cosigner takes on full legal responsibility for the balance alongside the primary cardholder.
Where You Can Still Find a Cosigner Option
The shift away from cosigners at the big national issuers happened gradually over the past decade, as those companies moved toward individual underwriting, authorized user programs, and secured cards.
Smaller credit unions and regional banks are where the option tends to survive. These institutions often use manual underwriting, which gives them room to evaluate two applicants together. Credit unions serving specific groups — military members, educators, local communities — are more likely to offer joint or cosigned credit card products. Call the lending department directly and ask whether their credit card allows a co-applicant or cosigner, since this often isn’t spelled out on the website.
Some institutions offer joint credit card accounts instead of cosigned ones, and the difference matters. A joint account gives both people equal ownership and access. A cosigned account typically gives one person the card and the other person only the liability. Either way, the issuer can consider the combined income and assets of everyone who will be liable on the account when deciding whether to approve the application and what credit limit to set.1Consumer Financial Protection Bureau. 12 CFR 1026.51 Ability to Pay
Cosigner, Joint Holder, and Authorized User Are Not the Same
These three roles look similar from the outside and carry very different legal exposure. Before you sign anything, be sure you know which one you’re agreeing to.
A cosigner guarantees the debt but usually has no control over the account. They cannot make charges, request a credit limit change, or close the account. Their only role is to back the primary cardholder’s obligation with their own credit. Federal law bars a creditor from requiring a cosigner if the primary applicant already qualifies for the credit on their own.2Consumer Financial Protection Bureau. 12 CFR 1002.7 Rules Concerning Extensions of Credit
A joint account holder applies together with the other person, goes through a credit check, and shares equal rights to use the account. Each joint holder can make purchases, request limit changes, and access account information. Both are individually responsible for the entire balance, not just their own charges.
An authorized user is added to someone else’s account and receives a card, but generally isn’t liable for the balance and has no control over account terms. The account’s payment history usually appears on both credit reports, which can help build credit if the account is managed well or hurt it if payments are missed.
Because true cosigner arrangements are rare, what a smaller institution actually offers may be a joint account or an authorized user setup under a different label. Ask specifically which one you’re getting.
The Rule for Applicants Under 21
Federal law addresses cosigning directly for one group of applicants. Under the Credit CARD Act of 2009, no credit card may be issued to someone under 21 unless they have a cosigner who is at least 21, or can show independent income sufficient to repay the debt.3Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans
If a cosigner is used, that person must sign the application and accept joint liability for all charges made before the younger applicant turns 21. The cosigner can be a parent, legal guardian, spouse, or any other adult with the financial means to repay.3Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans An under-21 applicant with a qualifying job doesn’t need one.
What the Cosigner Is Legally Agreeing To
Before you become obligated on the account, the creditor must give you a separate written document called a Notice to Cosigner. Federal law requires this notice to explain, in plain language, that you may have to pay the full amount of the debt if the primary cardholder doesn’t pay, that the creditor can come after you without first trying to collect from the primary user, and that a default will appear on your credit record.4eCFR. 16 CFR 444.3 Unfair or Deceptive Cosigner Practices
The legal standard behind that notice is called joint and several liability. In practice, the creditor doesn’t have to split the bill or try the primary cardholder first. It can demand the entire balance, including interest, late fees, and collection costs, from whichever party is easier to collect from. Your responsibility runs until the balance is paid in full and the account is closed.
This is the sharp line between cosigning and being an authorized user. An authorized user can generally walk away from the account without owing anything. A cosigner cannot. Even charges you didn’t approve are legally yours to pay.
How Cosigning Shows Up on Both Credit Reports
A cosigned account appears on both parties’ credit reports from the moment it’s opened. That cuts both ways.
If the primary cardholder pays on time and keeps the balance low relative to the credit limit, the account helps both scores. Miss a payment and it lands on both files. Run up a high balance and the increased credit utilization ratio can drag down both scores, even if the cosigner never made a single charge.
The cosigner usually has no way to control day-to-day spending on the account, so someone else’s habits directly affect your credit without your ability to manage them in real time. Checking your credit report regularly is the practical way to catch problems early.
What Happens If the Primary Cardholder Stops Paying
If the primary cardholder defaults, the creditor can pursue the cosigner using the same collection tools available against the primary borrower, including lawsuits, wage garnishment (subject to federal and state limits), and reporting the delinquency to the credit bureaus.4eCFR. 16 CFR 444.3 Unfair or Deceptive Cosigner Practices The creditor does not have to exhaust efforts against the primary user before turning to you.
If you end up paying the debt as a cosigner, you generally have the right to sue the primary borrower for reimbursement. A private indemnification agreement signed at the outset gives you a contractual basis to recover what you pay, though enforcing it may still require court.
If Part of the Debt Is Forgiven
If the creditor eventually forgives or cancels any part of the balance, the IRS generally treats the forgiven amount as taxable income. When two people are jointly liable, each may receive a Form 1099-C showing the full canceled amount. How much each person actually reports depends on factors like how much of the debt each person benefited from, state law, and whether either qualifies for an exclusion such as insolvency.5Internal Revenue Service. Publication 4681 (2025), Canceled Debts, Foreclosures, Repossessions, and Abandonments If your total debts exceed your total assets, the insolvency exclusion can shelter some or all of the amount.
Getting Off a Cosigned Account
Ending a cosigner’s obligation is hard. Unlike an authorized user, who can simply be removed by the primary cardholder, a cosigner’s liability is built into the original credit agreement. In most cases the obligation ends only when the entire balance is paid and the account is closed, which typically requires both cardholders to agree.
Some issuers may allow the account to be transferred to the primary cardholder alone if that person now qualifies independently, but this depends on the issuer’s policies. Refinancing the balance onto a new individual account is another route. Until the cosigner is formally released or the account is closed and paid off, the obligation continues, even if the cosigner cuts up the card and stops using the account.
Lower-Risk Alternatives
Because cosigning carries real financial exposure and few major issuers still offer it, alternatives that achieve similar goals are often the more practical route.
Adding someone as an authorized user to an existing card lets them build credit from the account’s payment history. The primary cardholder keeps full control and can remove the authorized user at any time, without the joint and several liability that comes with cosigning.
A secured credit card requires a cash deposit, often equal to the credit limit, and works like a normal card from there. Payments are reported to the credit bureaus, so history builds over time. No cosigner is needed because the deposit reduces the issuer’s risk.
A credit-builder loan, offered by some credit unions, is designed specifically to establish credit. The borrowed amount is held in an account while you make payments, and those payments are reported to the credit bureaus.
For someone who mainly needs a credit history rather than a high credit limit, a secured card or an authorized user arrangement is usually the more workable path than tracking down an issuer that still allows cosigners.
