Tax calcuated by IRS table is inconsistent with TurboTax's calculation.

Dear Experts,

I am filling my taxes as married filling jointly. I calculated my federal tax using the IRS table given in form 1040's instruction on page 77 (see the table in screenshot). I entered the income of line 15 using the 1040 generated by TurboTax. However, the result is inconsistent with what TurboTax is showing as the tax on line 16.

Is this possible? Under what situations this could happen?

If you had qualified dividends or capital gains they are taxed at a different rate.

There are like 7 different ways to figure the tax.  

It depends what kind of income you have. Even though the full amount shows up in the total income on the 1040 line 7, if you have capital gains or qualified dividends the tax is not taken from the tax table but is calculated separately from Schedule D. The tax will be calculated on the Qualified Dividends and Capital Gain Tax Worksheet. It does not get filed with your return. In the online version you need to save your return as a pdf file and include all the worksheets to see it.

For the Desktop version you can switch to Forms Mode and open the worksheet to see it. Click Forms in the upper right (upper left for Mac) and look through the list and open the Qualified Dividends and Capital Gain Tax Worksheet.

See….(this should say line 16 for 2021)

Thanks a lot @VolvoGirl. Nicely explained response. So, I am trying to understand that what am I missing. The table IRS instruction asks to use the value in line 15 in the table I gave in my initial post. When I use that the values are inconsistent. So, what instructions am I missing?

Thanks,

I thought I explained how to see the tax calculation Turbo Tax used.   Another place is IRS instructions Worksheet on page 30

Also, you need to elaborate on the word "inconsistent."   We don't know if that word means TurboTax calculated your tax higher than you expected or lower than expected.   There are different reasons for each scenario.

Are you using desktop software (CD/download) or Online TurboTax?
