Effective Tax Rate in Error - Bug?

[user17714745664]

The calculation of effective tax rate is not correct (way low).  Effective tax rate is a simple calculation ((Total Tax / Taxable Income) x 100%).   Some sources compute it based on AGI, so I'll show both. In either case, TurboTax's result doesn't line up with either.

TurboTax shows an Effective Tax Rate of 5.41% when my Total Tax is $23,282 and Taxable Income is $73,925.  The correct result is 31.49%.

If using AGI ($137,370) as the denominator instead, the result is 16.95%.

What numbers does TurboTax use to calculate Effective Tax Rate?  I can't figure it out and the discrepancy makes me a bit concerned about the overall integrity of the product.

I figured out how TurboTax is calculating Effective Tax Rate, and it appears to be correct when figured against AGI.  The issue is the "Total Tax" includes self-employment tax (FICA & Medicare) paid and the Effective Tax Rate excludes self-employment tax (correctly).  Tax paid w/o self-employment tax is $7435, which is 5.41% of AGI.

Would be nice if the cover sheet summary reminded users that the Total Tax is not Income Tax but includes other taxes paid via the 1040 reporting process.
