Q&A: Credit scores measure Dad’s accounts, too

Dear Liz: I recently added myself onto my 95-year-old father’s two credit card accounts as an authorized user. I am his agent under a power of attorney and handle his finances. I noticed that after being added to those accounts, my credit scores increased. When he passes on, I plan to close those accounts. Will my credit score be negatively affected?

Answer: Possibly. Closing accounts doesn’t help your scores and may hurt them. Scoring formulas are sensitive to the amount of credit you have versus how much you’re using. Closing an account shrinks your available credit, and the formulas don’t like that.

If you have good scores and plenty of other open accounts, though, the damage from closing these accounts probably will be minor and short-lived.
