Should You Make Your Boyfriend/Girlfriend an Authorized User on Your Credit Card?

Sharing a credit card with your partner can feel like a natural step if you already split bills or plan for the future. It looks simple with one account, one payment, and quicker rewards. But the bigger question is whether you are ready to trust someone else with your credit.

In Canada, the choice can be more difficult. Many banks do not report authorized-user activity to credit bureaus, so your partner may not get the credit boost you expect. This makes the decision less about convenience and more about real risks.

Adding your partner as an authorized user can make shared expenses easier and help you earn more rewards — but you are fully responsible for every dollar they spend. And if the relationship ends or they overspend, you’re still legally on the hook for the payments, even if they walk away.

Before making a decision, it’s important to weigh the benefits, the risks, and the safer alternatives. The guide below will help you decide whether adding your partner strengthens your finances or creates unnecessary risk.

What Is an Authorized User?   

An authorized user is someone you add to your credit card account. They get their own card linked to your account, but aren’t legally responsible for paying the bill. That means if your partner is an authorized user, they can use your credit line without applying for a card themselves. 

You keep control of the account (you pay the bills), and they simply have permission to charge to it. Many Canadian cards allow adding family or friends this way. It’s different from a joint account or co-signer: with an authorized user, the primary account holder   (you) does all the credit checks and payments, while the partner just has card access.

Pros of Adding Your Partner as an Authorized User 

Adding your partner to your credit card can be helpful if you set clear rules.

• Credit access and rewards. If your partner has little or bad credit, being an authorized user lets them use credit without qualifying on their own. In some countries, this can even build their score if issuers report on-time payments and low balances. Even if it doesn’t, their purchases still earn rewards for you. Groceries, gas, and other spending add to your cashback or points. Some banks also give bonus points for extra users.
  
• More rewards together. Because you cover the bill, you also earn the rewards from both your spending and your partner’s. This helps with shared costs and lets you build cashback or travel points faster.
  
• Convenience and trust. If you split bills, one account makes things easier. For newcomers or students who can’t qualify on their own, being added is a simple way to start using credit. With clear limits or agreements on repayment, this can work like a shared account without making both parties legally responsible.

Cons of Adding Your Partner as an Authorized User

There are also risks you should weigh carefully.

• You’re responsible for all charges. No matter who spends, you pay the balance. If your partner overspends, you carry the debt. This is common since people often spend more when it’s not their account. The risk is greater if the relationship ends and you don’t remove them quickly.
  
• Credit score impact. Any high balance or late payment on the account affects your credit. If your partner maxes out the card or misses a payment, your utilization and history can take a hit. In some cases, if issuers report authorized users, your partner’s credit could also be harmed by your mistakes.
  
• Limited benefit in Canada. Many Canadian banks don’t report authorized users to credit bureaus, meaning your partner usually won’t see any score boost. If your main goal is to help your partner’s score, look instead at best newcomer credit cards or best secured credit cards.
  
• Fees and trust. Some issuers charge $50–$75 for each extra user. Even when there are no additional card charges, the real “cost” comes down to trust. If your partner is careless, you pay the price.

Special Considerations for Canadian Couples

In Canada, being an authorized user usually does not help build credit. Equifax or TransUnion may not list the account at all, which means your partner gains little beyond spending access. A better option may be co-applicant or family cards at major banks like RBC or Scotiabank, though these require shared responsibility and sometimes proof of income. Before deciding, confirm with your bank whether they report authorized user activity.

Alternatives to Adding an Authorized User

If adding your partner as an authorized user feels risky, there are other ways to share spending or build credit.

• Separate cards. The simplest option is for each person to have their own card. Even with fair credit, your partner may qualify on their own. Secured cards, backed by a deposit, are a reliable way to start building credit. Student cards are another option, designed with lower entry requirements and modest limits.
  
• Joint accounts or co-signing. Some banks let couples apply together for a joint credit card or allow one to act as a co-signer. Both share responsibility, so missed payments affect both credit scores. Still, this setup can make household budgeting easier and works well for long-term partners. However this is very rare and not common in Canada.
  
• Building credit in other ways. Credit history can also grow through everyday bills. Putting a phone plan, utility account, or renter’s insurance in your partner’s name helps. A low-limit secured card used responsibly can also strengthen their profile over time.
  
• Prepaid or debit cards. If your only goal is shared spending, not credit building, a prepaid Visa/Mastercard or joint bank account is safer. These options don’t affect credit scores, and they remove the risk of debt.

Tips for Managing a Shared Card Safely

Thinking of adding your partner as an authorized user? Keep these steps in mind:

• Set rules early. Agree on budgets and what they can use the card for.
• Check together. Go over the monthly statement side by side.
• Use card tools. Many banks let you set limits or block certain spending.
• Act fast. If problems come up or if the relationship ends, remove the user right away.
• Be clear. Credit applications in Canada must list all users and co-borrowers.

When handled with honesty and structure, sharing a card can work. But remember: as the main account holder, you’re always responsible for the debt.

Conclusion

Making your partner an authorized user is ultimately a question of trust and timing. It can work well if you’re both aligned on spending, want to share rewards, or need a simple way to manage household expenses together.

But the risks are real. Since you’re responsible for every charge, any overspending or late payments could harm your credit. And in Canada, adding someone as an authorized user may not even help build their credit history.

The bottom line: think about your goals, your partner’s habits, and how much trust you share. If you move forward, treat it like any financial partnership, set clear rules, review statements together, and use safeguards. If not, building credit separately or choosing joint-friendly options may be the smarter path.
