¹ The Total Adjustments values represent tax returns that reported any amount for Total Adjustments (2021 IRS Form 1040, Line 10). The total counts show the distinct number of tax returns with any number of adjustments. The total dollar values are not a sum of the adjustments listed due to filing discrepancies and because this table does not list all possible adjustments.
