You aren’t the only one hiding a bank account from your spouse. According to a study released Wednesday by Creditcards.com, about 13 million Americans have maintained secret checking, saving or credit-card account without their partners’ knowledge. Young people were more likely than older folks to keep secrets and a slightly more women than men kept money out of sight from their partners. Matt Schulz, senior industry analyst at CreditCards.com said he was surprised by the number of Americans who hide accounts, especially because it “can cause some real damage in a relationship.” Not to mention their finances. “There’s no way to do a meaningful budget if you don’t know exactly what’s coming in and what’s going out.” (creditcards.com)
