Have you avoided paying your tax bill with a credit card because you just couldn't bear paying any more than you must to anyone on April 15th? I suspect many of you fall into this category, as do I. Even if the dollar amount is small, the thought of paying an additional 2.49% to cover the fee charged by credit card companies always makes me cringe. So, I continue to pull out the trusty checkbook, dust it off, and write one of the handful of checks I send out each year.
