The extended tax return due date is October 15, 2021. Please be aware that Missouri will not accept the federal extension form as an extension for your Missouri tax return. However, if you expect to owe income taxes, you should submit your payment with extension payment voucher Form MO-60. If you efiled your return and are making a payment by check or money order, you must complete a Form MO-60 on eFile.com. If you are making a payment by credit card, a Form MO-60 is not needed. If you are making an extension payment, you also must use Form MO-60 unless it is made electronically.
