Here's what we know so far:
https://www.nytimes.com/2024/08/22/us/politics/kamala-harris-tax-plan.html
"Ms. Harris would set the top marginal income rate at 39.6 percent, up from 37 percent. On top of that, she would also increase the rate on two parallel Medicare surtaxes to 5 percent from 3.8 percent for Americans making more than $400,000 and expand the income subject to one of them. Together, the Medicare and income proposals would create a top marginal rate as high as 44.6 percent."
Ouch. With state taxes, we'll be paying a marginal rate of greater than 50% taxes. That's just too much.
Harris also plans to: (i) increase corporate taxes and (ii) further increase the already ridiculous tax on corporate stock buy-backs. These ideas hurt everyone who owns stocks - that includes every single person with a 401/IRA/TSP.
Yikes.
