building credit

Dear Liz: Many years ago I took out a credit card to pay for my two children’s college expenses. They were authorized users for miscellaneous expenses. They no longer use or even have access to the cards. Now they are both in stable, well-paying jobs. I would like to keep the card but remove the authorized users. How would this affect their credit scores? Or mine, for that matter?

Answer: You helped your kids establish good credit by adding them as authorized users. Removing them won’t affect your credit scores. The effect on their scores depends on how well they’ve managed credit on their own.

The impact should be minimal if they’ve continued to build credit by opening their own credit cards and paying those on time. Ideally, for credit-building purposes, they’ll also have a solid history paying an installment loan, such as a mortgage, student loan or auto loan.

If they haven’t used credit much and have a thin file — generally, fewer than five accounts showing on their credit reports — the damage might be more significant. If that’s the case, you may want to delay removing them as authorized users while they open other lines of credit. They should know that they don’t have to carry debt to have good credit: Just using credit cards lightly and paying the balances in full should do the job.
