Tax Computation 2024 incorrect

crevitch — Sun, 02 Nov 2025 11:13:14 GMT

when I filed my 2024 taxes in april 2025, turbotax calculated the tax amount on line 16 of the 1040 about 400 less than it should be relative to the irs tax tables. When I used it today, the amount was correct. Was there a known problem? Is there another reason why the calculated value in line 16 does not match the tax tables?

The tax tables are often not directly used. The most common reasons are if you had Qualified Dividends or Long-Term Capital Gains, but the checkboxes on line 16 also show other possible reasons. Does that seem to apply?

Are you saying the amount changes without you changing anything else? Or are you re-doing something and may have entered something differently (for example, forgetting to enter that some dividends were "qualified" or that some capital gains were long-term)?

What did you do today when you opened it? What entries did you make? You need to compare lines 1-15 to the return you filed and see what else changed besides the tax on line 16.

It depends on what kind of income you have. There are like 7 different ways to figure the tax.

See the IRS worksheet on 1040 page 36 for how the tax is figured. Turbo Tax uses the same worksheet.

Even though it shows up as income on the first page,if you have capital gains or qualified dividends the tax on line 16 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 worksheets to see it.

In the online version you need to save your return as a pdf file and include all 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.

IRS Qualified Dividends and Capital Gain Tax Worksheet—Line 16 on 1040 instructions page 36. And you will need the IRS Tax Tables starting on page 64 or the Tax Computation Worksheet on page 76.
