Payments must be postmarked by April 15, 2015, to avoid interest and late payment charges. The Department of Revenue offers several payment options.
Check or money order: Attach a check or money order (U.S. funds only), payable to Missouri Department of Revenue. By submitting payment by check, you authorize the Department of Revenue to process the check electronically upon receipt. Do not postdate. The Department of Revenue may electronically resubmit checks returned for insufficient or uncollected funds. If you mail your payment after your return is filed, attach your payment to the Form MO-1040V found on page 40.
