The House File No. 100 proposed in Minnesota aims to adjust the taxation of Social Security income for residents. This bill proposes modifying how much Social Security income can be subtracted from state taxable income, aiming to potentially increase the amount that can be deducted, thus reducing the overall taxable income for individuals receiving Social Security benefits.

Specifically, the bill outlines two methods for calculating the subtraction: a simplified subtraction and an alternate subtraction, each depending on the taxpayer’s income level and filing status (e.g., single, married filing jointly, etc.). The bill sets thresholds on income levels, above which the allowable subtraction begins to phase out, decreasing by a certain percentage based on the amount by which the taxpayer's income exceeds these thresholds.

The intent is to help individuals, particularly those on fixed incomes from Social Security, by potentially lowering their tax burden. Simplifications and adjustments have also been proposed to make the application of these subtractions more straightforward and reflective of current economic conditions.
