Is the capital gain tax possible effective in 2021?

If Biden raises taxes, would that be effective this year or have to take effect next year?

 

The next US tax return we file would be for the 2020 income. That would be due April 15, 2021. The 2020 tax return would still be under President Donald Trump tax rules and subject to the reductions in tax that he put thru. Joe Biden if he raises taxes would affect your 2021 income that you file for April 15, 2022.

 

I don't know
