I'm using Turbo Tax Premier 2021 on Window 10.
I'm trying to figure out how Turbo Tax calculate the tax.
Using the amount on line 15 of 1040, it show some X value. If I use the 2021 tax table from IRS, it it does not result the same value what Turbox Tax is calculated on line 16. Turbox Tax calculation is way more than the tax table calculation.
Furthermore investigation, Turbox Tax does not use Tax Table. It use "Qualified Dividends and Capital Gain Tax Worksheet". And on that worksheet, line 22, it refer to another "Tax Computation Worksheet". But I can't find any form call "Tax Computation Worksheet".
Regardless of how tax is computed, using "Tax Computation Worksheet" or "Tax Table", they should result in the same value. Correct? Why am getting different result? Is my understanding on how to use tax table is wrong?
How do I validate and verify that the tax calculation is accurate?
Has anyone ever question this or do we simply just accept the fate of TT code to be the master of tax calculation?
