I think it's actually a tax credit so it applies mostly to higher income people. If you're Doing overtime at McDonalds you probably are getting a tax refund already so the tax credit doesn't even help you.
Its not. Higher income people are "exempt" so don't get regular overtime. I know from experience.
Because I'm salaried and my employer pays my overtime at a fixed converted hourly rate based on my salary, I can't claim that tax credit. There's no 0.5 to save taxes on. I get paid 1.0 overtime.
And as you said, most hourly workers who DO get the 0.5 don't save on taxes either because they make so little to start with.
It was a gimmick bait and switch that doesn't help hardly anybody.
