Have you ever figured out what percentage of your gross income you pay in federal tax?

I’m interested in what you pay as a percentage of your total gross income. Include interest income, the whole total total. I don’t know what line it is on the tax forms. Do you know the percentage? If you calculate it now, are you surprised by the number? Higher than you guessed? Lower?

The math is take your total tax due and divide it by the your total gross income (not the adjusted gross, which is what you use for the tax tables). Then multiply by 100 to move the decimal point.

Example: if you earned $40k and paid $8k.

I think it is lower than what most people think, but I really have no idea.

8,000/40,000=.2
.2×100=20%
