Marijuana Tax Reporting Guide

What can you do to avoid your account becoming past due?
  • Know your tax responsibilities and plan for them.
  • It is recommended that you set up a separate account for your tax obligations and regularly deposit collected excise tax or other taxes you may owe. Withdraw the funds only when you pay the taxes.
  • Pay attention to the tax return due date - monthly sales are to be confirmed and marijuana excise tax paid on or before the tax due date of the following month.
  • Pay your tax obligation early to allow for issues with your bank (if using ACH, checks) or the post office.
  • If mailing your payment, we recommend that you go into the Post Office and request they hand stamp your envelope with the mailing date.
  • Check your email for Balance Due Notices and respond promptly with your payment for the amount due.
  • Promptly notify the Liquor and Cannabis Board if your address and/or phone number changes by sending an email to with your UBI and license numbers, old information and new information.
