Why was I shown 123 to file taxes plus sales tax before I submitted my card but then on the next page you show 143.00 was charged plus sales?

So I screenshot the amount before I submitted payment. My federal was 59.00 and state 64.00 + sales tax. I submit my payment and I'm seeing 79 for Federal and 64 for state plus sales tax??? That's really fraudulent work. You snuck in an extra $20. That's not right WHATSOEVER. $20 is $20, and at the rate this is charging for taxes it's already a crime. Let alone sneak change prices.

Seems like there was a price increase.   You can always pay early to lock in a current price.
