 TITLE: The Worst Credit Card Charges You Can Make CONTENT: Taxes\n-----\nWhile you can't pay your income tax bill directly to the IRS with a credit card, you can use a third-party payment service—for a price. The convenience fees these companies charge are nearly 2% of the amount you pay, and can be even higher if you use a tax preparation software's system. These fees will not just increase your liability, but if you spread the debt out over many months, the accumulated interest will be expensive. For example, the fee for an $8,000 bill might be $160. And if your credit card has an 18% APR and it takes you a year to repay, you'll pay nearly $800 in interest. It's best to find other ways to pay your debt, such as using savings or contacting the IRS to work out a solution. END
