What's missed by a lot of people is that the 250k is AGI not Gross. You're probably closer to 400k to 500k as an individual employee to even be affected since that income level tends to have 401k, mortages, and other tax credits that bring that AGI down.
The second thing is that you're only paying the higher rate on the amount over 250k AGI. So... if your household makes 300k AGI, you're really paying the extra 2% on the 50k or your taxes go up 1k.
The third thing that I hear and people seem not to understand is that businesses pay taxes on profit not gross income. If you're an S corp for instance, you have to clear over 250k in profit to even start to be affected. If your business grosses 1 million dollars but your profit from it's 300k, then you're going to pay the extra 2% on the extra 50 k as the example above.
My point isn't to say it's good/right or even to say it's fair. My point is that people throw around that 250k number without understanding that it's AGI.
Should it be 500k AGI, 10 Million, or a flat tax, people need to understand what is being presented because I hear a lot of people who keep saying they make 250k with their spouse's income and if that's gross, you aren't going to be affected at all because 1) Your AGI will be lower 2) You just hit the floor of the increase so it's anything above that that will be taxes at a higher rate.
