What happened in a nutshell is that in accordance with the gop tax bill, they changed the withholding tables to give people more immediate cash in their paychecks leading up to the 2018 midterms. But that meant not enough was being withheld for most people, and here we are. A lot of people may even have an overall lower tax obligation, but don’t don’t feel the enjoyment of it because they now owe a hefty amount.
The other bad news is that the temporary cuts people got to fund the permanent corporate cuts are temporary, and by law will be heading back up in the mid 2020’s unless congress passes another round of tax cuts.
People who itemize in blue states are most likely paying more because of the cap on salt deductions.
