It is extremely counterintuitive, but it is pretty much what they did. You pay 10k or whatever in taxes instead of 8k or 9k, and after the new system of credits and revised deductions is applied, you end up with more money in your pocket. This is primarily true for parents, married ones with children under 18 more so than married with college aged kids (unless the 529 stuff is adopted) and those more so (due to higher income) than single parents.
The basic structure is less true for high-earning married couples without kids and high-earning singles in particular.
I was hoping to do a post or two of examples, but I am not likely to have time for that. If I do get time, I will run through some typical examples.
This calculator was just put up. It overstates tax paid by EITC eligible people and also leaves out some common deductions and doesn’t apply the tax credits properly, but it’s a decent starting point and you can tweak the finished numbers from there.
