You have to make sure that the transaction is recorded somewhere. The form requires proof of your action. This is why it is important to provide the transcript of the operations. However, you can use the Missouri Department of Revenue Service to pay online. You still have to check out the original information that Department requires from you. Authorities have stated several addresses you can send the file with the money’s check attachment, and you can send it electronically via email. You can also use regular mail if you want to send the form in paper version. In this case, send it to the Sales and Use or Transient Employer Withholding Taxation Division.
