E filing is still the best and most accurate way to file your taxes and the fastest way to get your refund. However, even if you have to pay in the E filing process is still the best. You can file early and wait to pay on the deadline day of April 15. Help and answers are available on the state tax commission web site and you can make your pay directly from that site. You are also being encouraged to change your W-4 form is you had less of a refund this year or had to pay in extra.
