Add an authorized user when you're building credit for someone who needs it, or when you're sharing a premium card's perks with a person who will use them. Skip it otherwise, because you stay legally responsible for every dollar they charge.
The fee matters more than it used to. Chase lists $195 for each authorized user on the Sapphire Reserve, and the Amex Platinum is reported at the same $195 per additional card (confirm it in Amex's pricing terms). This guide covers how authorized user accounts report to the bureaus, who benefits, who shouldn't bother, and which cards are worth the fee.
What an Authorized User Actually Is
An authorized user is a person added to an existing credit card account who can make purchases but isn't legally responsible for the balance. The primary holder owns the debt. The authorized user gets a card with their name on it, sometimes their own card number, and whatever benefits the issuer extends to them.
The mechanic that makes this worth doing is bureau reporting. Many major issuers report the full account history to the authorized user's credit file. An authorized user added to a ten-year-old account with perfect payment history and low utilization can inherit that history, which can improve their average age of accounts, payment history and utilization.
Issuers differ on reporting and on minimum ages, so confirm the current policy with the issuer before you rely on this strategy. Our guide to the minimum age for authorized users covers the age question card by card.
The Five Real Benefits
1. Credit building, especially for thin files. A teenager added to a parent's long-standing, well-managed account can start a credit file before they ever apply for a card. The same effect works for an immigrant building a U.S. credit file, a spouse who has never had credit in their name, or a partner rebuilding after bankruptcy.
2. Shared benefits on premium cards. Chase says Sapphire Reserve authorized users get their own Priority Pass Select membership, with two guests each. Amex Platinum additional cardmembers are reported to get lounge access and hotel status of their own, though the card's statement credits are shared. Check each card's terms for what an additional card includes.
3. Family expense visibility. If you're managing a household budget and your spouse is buying groceries on a separate debit card, you lose the points and the visibility. One card, both authorized, and the spend lands on a single statement.
4. Multipliers on family spending. Putting a college kid on an Amex Gold means their grocery spending at U.S. supermarkets (not Walmart, not Target, not Costco) earns 4X points, up to $25,000 a calendar year. That's real points on spend that would otherwise sit on a debit card.
5. Welcome bonus spending. On the Chase Sapphire Preferred, Chase says purchases an authorized user makes count toward the new cardmember bonus. If a household is chasing a minimum spend, that helps.
The Five Real Risks
1. You are responsible for every dollar charged. This is the one most people gloss over. If your authorized user runs up $4,000 on the card and refuses to pay you back, the issuer comes to you. The authorized user has no legal obligation. Your statement, your balance, your problem.
2. Their behavior affects your credit, indirectly. They can't directly damage your credit, but they can cause you to miss payments, max out the card, or carry balances. All of those hit your credit, not theirs.
3. Their credit can inherit your bad history too. Reporting runs both ways. If you carry a balance and pay late, the account that lands on your authorized user's credit report shows that history. You can build credit for a kid by adding them, and you can also damage it.
4. The fee per authorized user can be steep. Chase Sapphire Reserve is $195 for each authorized user. The Amex Platinum is reported at $195 per additional card. On the Venture X, adding an authorized user is free, but lounge access now costs extra for each one (details below).
5. Removing them isn't always clean. Once an account is on someone's credit report as an authorized user account, removing them usually removes it from their file too. That can drop their score if it was their oldest account. Plan the exit, not just the entry.
Best Cards for Authorized Users
The card matters more than the strategy. These four are the ones to consider.
Capital One Venture X
The Venture X is the value pick for lounge access, with a catch. Adding authorized users carries no fee, but since February 1, 2026, lounge access for each authorized user costs $125 a year, up to four users. Capital One's own page says some benefits are only for the primary accountholder, so check the lounge terms before you add anyone. Even with the lounge fee, that's cheaper than the Reserve's $195 if lounges are the goal. Our Venture X review covers the rest of the card.
Chase Sapphire Preferred
The Preferred is the credit-building pick. The $95 annual fee plus no per-user fee makes it a low-cost way to put a young adult on a card with a meaningful trade line, without the $195-per-user cost of the Reserve. Chase says authorized users can also activate the card's DashPass membership. Our Sapphire Preferred review has the full earn and benefit structure.
Amex Gold
The Gold is the family-spending pick. It earns 4X at U.S. supermarkets (up to $25,000 a calendar year) and 4X at restaurants worldwide (up to $50,000), so a household pooling grocery and dining spend can put serious points on the card. Amex says you can add up to five additional cards with no fee, then $35 for the sixth and beyond. Practical caveat: Costco, Walmart and Target don't code as supermarkets at Amex. Check before you assume. Our guide to when the Amex Gold beats a travel card shows where it fits.
Chase Sapphire Reserve
The Reserve is the premium pick, and the most expensive authorized user on this list at $195 each. It only pencils out if the authorized user will actually use the Priority Pass Select lounge access, the travel credits and the broader insurance package. For a spouse who travels with you often and would otherwise need a premium card of their own, the math works. For an in-law who flies twice a year, it doesn't. Our Sapphire Reserve review walks through the credits, and the Sapphire Showdown compares the Preferred and the Reserve. For the Amex side, see our Amex Platinum authorized users breakdown.
Who Should Add an Authorized User
Add an authorized user if:
- You have a teenager or young adult and want to start their credit file before they apply for their own card, and the card's minimum age allows it.
- You have a spouse or partner you trust with the account, and combining spend simplifies budgeting and earns more points than splitting it across two cards.
- You have a parent rebuilding credit after a bankruptcy or divorce, and you have a clean, long-history account that would meaningfully help their file.
- You travel often with the same person and want them to have lounge access or hotel status without paying for their own premium card.
Who Should Skip It
Don't add an authorized user if:
- You don't trust the person fully with your account. The "I'll just take the card away" plan doesn't work, because they may have the card number memorized and you're on the hook for any charge until the card is closed or a new number is issued.
- The fee per authorized user exceeds the value of the benefits they'll actually use. $195 for a Sapphire Reserve authorized user who flies twice a year is bad math.
- Your account has a problematic history (late payments, high utilization, recent over-limit fees). You'll transfer that history to their credit file.
- They already have strong credit of their own. The strategy is most powerful for thin or damaged files.
Five Ways to Minimize the Risk
1. Don't give them the card. Many issuers let you add an authorized user without handing over a physical card. The account can still report while the spending risk never appears. This is the safest way to use the strategy purely for credit building.
2. Set spending alerts and limits. Chase, Amex and Capital One all offer alerts or spending controls in their apps. Use them. A monthly cap on a kid's card eliminates most of the catastrophic-charge risk.
3. Document the repayment arrangement in writing. If your authorized user is going to pay you back for charges, put it in a text or email at minimum. Verbal agreements get re-remembered when the relationship gets complicated.
4. Monitor the account weekly. Authorized user status doesn't relieve you of responsibility, so treat the card like you're carrying the risk, because you are.
5. Plan the removal in advance. Decide upfront when the authorized user comes off the account. A kid hits 21, opens their own card, and gets removed from yours. A spouse keeps their status indefinitely. A friend who needed credit building gets six months. Set the timeline, then execute it.
Alternatives to Adding an Authorized User
Adding an authorized user isn't the only way to solve the underlying problem.
For credit building: A secured credit card or credit-builder loan reports the person's own activity to the bureaus, in their name, with no risk to you. It builds more slowly, but the credit is genuinely theirs. Our best authorized user credit cards roundup includes secured-card alternatives.
For shared spending: Two separate cards with the same issuer can keep credit reporting fully separate. The downside is two annual fees. The upside is no shared liability. Our guide to joint credit card accounts covers the other way to share an account.
For travel benefits: A standalone Priority Pass membership may cost less than a premium card's per-user fee. If lounge access is the only reason to add an authorized user, check Priority Pass's current prices first.
Next Step
Decide the goal first. If it's credit building, add the person to your oldest, best-managed account and consider never handing over the card. If it's sharing perks, compare the per-user fee with what they'd really use, and skip the fee when the answer is a couple of trips a year.
