Confused about the difference between ordinary income and capital gains!

Hi everyone,

I’m relatively new to equity compensation, and I keep getting conflicting advice on when the tax man actually takes his share. I started looking for a how are rsus taxed calculator to understand the impact of holding my shares for a year versus selling them immediately upon vesting. It seems like the initial vest is always treated as regular salary, which is a bit of a bummer for my tax bracket. Has anyone found a clear how are rsus taxed calculator?

Thanks in advance.
