Tax season and credit cards seem to go hand-in-hand like peanut butter and jelly, at least if you believe the findings of a recent study conducted by Credit Card Insider. Using SurveyMonkey to conduct an online survey of 3,114 adults from Feb. 3-5, Credit Card Insider found out the following information when it comes to how important credit cards are for people during tax season. 14% of respondents who expected to owe this year planned on using a credit card to pay their taxes. Of those expecting a tax refund, 40% had credit card debt. 75% of those with debt plan to use their tax refund toward paying it off.
