I did ours from memory. Over $3k increase for us. Thanks Republicans!
$3k?! Wow, I didn't think that was possible. Worst case for us would be about a $700 tax increase, but that depends on the amount of itemizing we would have done that gets negated by the higher standard deduction.
Honestly, I wish they would have helped retirees out by raising the income threshold at which Social Security benefits get taxed. Annoying that California, New York, and Illinois don't tax SS at all and the federal government does at a certain income level.
As a tax preparer, I am interested in what is your unique circumstances that causes your taxes to go up by 3k when most going down. It would help me to warn my clients.
