Tax computation

[yar]

My taxable income is $217,755 as computed by TurboTax. Then TurboTax computed our federal income tax as $38,367 for filing married jointly.

Using the exact same taxable income, the tax manually computed per 2021 1040 instruction page 77, Section B is $40,303.

 Can you check on this? Thank you.

The tax calculators, tax bracket calculations, and tax tables all calculate income tax based on ordinary income.  They do not take into account items such as qualified dividends or capital gains that are taxed at a lower rate than ordinary income.  If a portion of the total taxable income was due to qualified dividends or capital gains, then the overall tax will be less.  How much less will depend on how much of the income is being taxed at a lower rate.

The worksheet used to calculate your taxes when taking capital gains into account is found in the IRS Instructions for Form 1040.  It is called the Qualified Dividends and Capital Gains Tax Worksheet.  This worksheet will be included as part of your tax return if it is being used to calculate your tax.
