How did the Federal taxes we owe go from $6231 to $9222? As you can see, not much changed from 2020 to 2021. Married filing jointly. Total and Taxable incomes are a little less because of working less overtime. Took standard Deduction and we didn't change our W-4s. Can someone explain the huge difference? We did sell a house and then buy a house in September 2020. Is that the reason?
