Distributors must file a monthly report with the Tax Commission — Form 1450, Distributor’s Fuel Tax Report. The report is due the last day of the month following the tax period.
Form 1450
The form 1450 isn’t available on this website. We mail it with personalized information for each distributor. Here’s a sample of the form and the instructions:

License validation
Taxpayer Access Point (TAP) can help distributors validate suppliers’ and customers’ identities. You must register with TAP and be logged in to access this confidential information.
Transfer fee
Distributors are required to pay a 1¢ per-gallon transfer fee. The fee is on the delivery or storage of petroleum or petroleum products in Idaho.
How to file Form 1450 through TAP
You have three options for filing your Form 1450 through TAP:
- XML
- Excel Template
- Manual Data Entry
XML
You can use your usual software vendor if your vendor supports fuels tax reporting and can produce a correctly formatted XML file that follows Idaho’s requirements. You can also create your own XML solution. See below for the latest Schema and Change Log.
TAP’s verification process reviews your file for these items:
- Does the file match Idaho’s XML schema? TAP will highlight errors for specific line numbers.
- Does the report’s filing period match the selected filing period?
- Does the account number in the report match the TAP account? (The account number may also be called “permit number” or “state license number.”)
- Does the taxpayer’s tax ID number (EIN or SSN) in the report match the one associated with the TAP account?
- Your filing will undergo more reviews as it processes.
Excel Template
You can find a copy of the Form 1450 Excel template on TAP by selecting the File Return link for the desired reporting period. The template has one sheet of instructions and three sheets of data that you must fill out. Don’t change or rearrange the columns when copying data into the Excel template.
Manual Data Entry
Fuel Distributor Tax Return forms include:
- Distributor Report Details
- Schedule of Disbursements
- Schedule of Receipts
The forms allow manual data entry through the TAP filing process. You can enter data manually for an entire form or make adjustments to the Excel template after you’ve uploaded it.
