2022 Production Tax Rate

The 2022 Production Tax base rate is $3.063 per taxable ton. Additional tax of 3 cents per ton applies for every 1% the product’s iron content exceeds 72%, when dried at 212 degrees Fahrenheit.

The Production Tax rate is indexed each year, based on changes in the Gross Domestic Product Implicit Price Deflator (GDPIPD). To calculate the rate, we multiply the previous year’s rate by the percentage change in the 4th quarter GDPIPD, as shown below. 

​2021 Rate x​ ​(2021 IPD/2020 IPD) ​= ​2022 Base Rate
​$2.892 ​x ​121.188/114.439 ​= ​$3.063

The GDPIPD is published each quarter by Bureau of Economic Analysis, part of the U.S. Department of Commerce. View the most recent GPDIPD data on the Bureau of Economic Development webpage.
