Joint Credit Card Accounts, Explained
What a joint account is
On a true joint account, both people are primary owners, equally liable for the entire balance, and both have full control. It differs from an authorized user, who can spend on the account but is not legally responsible for the debt. Joint accounts give both parties equal standing and equal risk.
Why they are rare now
Most large U.S. issuers have quietly discontinued new joint credit card accounts, partly due to the complexity of removing a co-owner. So in practice, the realistic options today are one person as the primary with the other as an authorized user, or each person holding their own cards. A few smaller issuers still offer joint accounts.
Better options for couples
For shared spending, adding your partner as an authorized user puts a card in their hands and can help their credit (see authorized user to build credit) without making them liable for the debt. Many couples also run a two-player strategy, each holding their own cards to double bonuses while sharing the rewards.
