Adding an authorized user can help their credit, but only if the account reports to the credit bureaus and stays in good standing
When you add someone as an authorized user on your credit card account, their credit report receives the full history of that account — every on-time payment, every late payment, every balance you carry. If the account has a long, clean payment history and a low balance relative to the credit limit, their credit score typically rises. If the account has missed payments or high balances, their score can drop.
The effect depends on three things: whether the card issuer reports authorized users to the credit bureaus, what that account's history looks like, and how much weight the credit scoring model gives to accounts that are not in the person's own name. Not all card issuers report authorized users. Some do it automatically; others require you to request it. Before you add someone, call the card issuer and ask whether authorized users appear on credit reports.
This is different from making someone a joint account holder. A joint account holder is equally responsible for the debt. An authorized user can use the card but has no legal obligation to pay the bill — you do. That distinction matters for credit reporting and for debt collection.
Key Takeaways
- Not all card issuers report authorized users to credit bureaus, so confirm with your issuer before adding someone expecting a credit boost.
- The authorized user's score rises if the account has on-time payments and low balances, and falls if the account has late payments or high balances.
- The authorized user receives the account's entire history, including any missed payments from before they were added.
- Adding an authorized user does not make them responsible for the debt — you remain the sole account holder and the person legally liable to pay.
- The credit score impact is usually modest because credit scoring models weight accounts in your own name more heavily than accounts where you are an authorized user.
Which card issuers report authorized users
The major issuers — Chase, American Express, Capital One, Discover, Bank of America, Citi — all report authorized users to the three major credit bureaus (Equifax, Experian, TransUnion). However, some smaller issuers and regional banks do not. A few issuers report to only one or two of the three bureaus rather than all three.
Call your card issuer's customer service line and ask: "If I add an authorized user, will that account appear on their credit report?" Write down the answer and the date you called. If the issuer says no, adding an authorized user will not change that person's credit score at all — they will have a card to use, but no credit benefit.
Some issuers let you choose whether to report an authorized user. If your issuer offers this option, you can add someone without reporting them, which means the account does not appear on their credit report and does not affect their score either way.
How the account history affects the authorized user's score
When an authorized user is added, the credit bureaus receive the account's entire history — not just the period after they were added. If you opened the account five years ago and have paid on time every month, the authorized user's report now shows five years of on-time payments. If you missed a payment two years ago, that missed payment appears on their report too.
Credit scoring models reward long payment history and low balances. If your account has both, the authorized user's score usually rises within 30 to 45 days of being added. The rise is typically 10 to 100 points, depending on how much their existing credit history needs help. Someone with no credit history sees a bigger boost than someone who already has several accounts in good standing.
If your account has late payments, high balances, or both, the authorized user's score can fall. A recent late payment (within the last year) has the strongest negative effect. High balances — anything above 30 percent of the credit limit — also drag the score down. If you carry a balance of $8,000 on a $10,000 limit, adding an authorized user to that account will likely hurt their score, not help it.
Why the boost is usually smaller than expected
Credit scoring models treat accounts in your own name differently from accounts where you are an authorized user. When calculating your score, the models weight accounts you opened and are responsible for more heavily than accounts where you are just an authorized user. This is because you have less control over an authorized user account — the primary account holder can change the balance, miss payments, or even close the account without your input.
A person with no credit history might see a 30 to 50 point boost from being added as an authorized user on a strong account. A person who already has several accounts in their own name might see almost no change, because the new account carries less weight in the scoring calculation. The boost is real but modest, and it disappears if you remove them as an authorized user or if the account later develops problems.
What happens if you miss a payment after they are added
If you miss a payment on the account after someone is an authorized user, that late payment appears on their credit report when ready. They have no way to prevent it or fix it, because they are not the account holder. The late payment will damage their score just as much as it damages yours.
This is why adding an authorized user to a card you are trying to rebuild is risky. If you are working your way back from missed payments, adding someone else to the account puts their credit at risk if you miss again. Wait until the account has at least 12 months of on-time payments before adding an authorized user.
The difference between authorized users and joint account holders
An authorized user can use the card but is not legally responsible for paying the bill. You, the primary account holder, are responsible. The card issuer will pursue you for payment if the bill goes unpaid, not the authorized user.
A joint account holder is equally responsible for the debt. Both names appear on the account, and both are legally liable to pay. If the bill goes unpaid, the creditor can pursue either person. Joint accounts are reported to both people's credit reports and affect both scores equally.
For credit-building purposes, being added as an authorized user is lower-risk because you have no legal obligation to pay. However, the credit benefit is also smaller because the scoring models recognize that you have less control over the account.
When adding an authorized user makes sense
Adding someone as an authorized user makes sense when you have a card with a long, clean payment history and low balances, and that person has little or no credit history. The boost to their score is real, even if modest. It also gives them a card to use for everyday purchases, which can help them build their own payment history if they use it responsibly.
It does not make sense if your account has recent late payments, high balances, or both. In that case, adding an authorized user will likely hurt their score. Wait until your account is in better shape.
It also does not make sense if the card issuer does not report authorized users. Call first and confirm. If they do not report, the authorized user gets a card but no credit benefit, so there is no reason to add them unless you straightforward want them to have access to the card.
Frequently Asked Questions
Can I remove someone as an authorized user if their credit score drops?
Yes. You can remove an authorized user at any time by calling the card issuer. Once removed, the account stops appearing on their credit report, and the negative impact gradually fades. Late payments and high balances stay on their report for seven years, but the account itself will no longer be listed.
Does the authorized user have to use the card for it to help their credit?
No. The account appears on their credit report and affects their score whether they use the card or not. The credit benefit comes from the account's history and balance, not from their activity on it. However, if they do use the card, make sure they pay you back so the account stays in good standing.
What if the authorized user has bad credit — will adding them to my good account hurt my score?
No. Adding an authorized user to your account does not affect your credit score. Your score is based on accounts in your own name. Their credit history does not change yours. However, if you later miss a payment on the account, that late payment will appear on both your report and theirs.
How long does it take for the credit score to change after someone is added as an authorized user?
The account usually appears on their credit report within 30 to 45 days of being added. The credit score change happens after that, once the scoring model recalculates their score with the new account included. Some issuers report faster; others take longer. Call your issuer to ask their typical timeline.
Can I add someone as an authorized user if they are not a family member?
Yes. Card issuers do not require authorized users to be related to the account holder. You can add a friend, business partner, or anyone else. However, you are responsible for the bill, so only add someone you trust with access to the card.
