Indiana MF-600 Form Instructions 2025

Form MF-600 is the designated tax return document used in Indiana to report “petroleum severance,” which refers to the extraction of hydrocarbons (like crude oil and natural gas) from the ground in either liquid or gaseous form. The form must be filed by any entity or individual who purchases or possesses this petroleum immediately after it has been severed from the land. Filing occurs on a monthly basis, with both the return and payment due by the last day of the month following the reporting period. For example, January’s report is due by the end of February. The form calculates the tax liability based on the volume and value of the extracted resources, comparing specific statutory rates (like $0.24 per barrel for oil) against a percentage of the product’s value to determine the higher tax amount owed.
