I’m learning the Schedule D Tax Worksheet and find the line 15 and 19 have a fixed amount per filing status. e.g. for head of of household, line 15 has 54,100 and line 19 has 164,900. It seems IRS sets different values yearly. What do we call these? They’re used in the calculation but I don’t find any explanations of what they are in IRS publications. Can you provide more insights?
