The Michigan Department of Treasury Form 3778, also known as the Three Day Payment Voucher, plays a crucial role in the state's tax collection process for imported or diverted motor fuels. This form is mandated under the authority of Public Act 403 of 2000, requiring timely filing to avoid penalties. It is primarily used by individuals and businesses that import fuel from outside the United States or divert fuel that was originally intended for export. The form collects essential information, including the company name, account number, contact details, and specifics about the fuel being imported or diverted. Tax rates vary based on the type of fuel, with specific codes assigned to gasoline, ethanol, undyed diesel, dyed diesel, and aviation products. The form also outlines the calculation of taxes due, penalties for late filing, and interest rates applicable to late payments. Importantly, failure to submit the form within three business days of the relevant event can result in significant financial penalties, underscoring the need for accurate and prompt compliance. By following the detailed instructions provided, filers can ensure that they meet all requirements, thereby facilitating a smooth transaction process with the Michigan Treasury.
