field_block:node:page:field_paragraph
You are required to file the Occupation Tax return if any of the following are true:
-
You remove or beneficiate mine ore, the product of which you have final control and ownership
-
You produce ferrous metals in Minnesota, such as taconite, semi-taconite, and iron ore; and direct reduced iron (DRI)
-
You produce nonferrous metals in Minnesota
- Contract mining
- Beneficiation or ore owned by someone else
- Leases of land or equipment
- Income received as royalties
- Any other non-mining income
You must file your annual Occupation Tax return by May 1. If that date falls on a weekend, the return is due by the next business day.
There is an automatic seven-month extension to file your Occupation Tax return, but you must pay 90 percent of the tax by May 1.
You are not required to submit a form to receive this extension. Also, if the IRS grants an extension to file your federal return that is longer than Minnesota's seven-month extension, the Minnesota due date is extended to the federal due date.
