I did a preliminary pass on my 2018 taxes this weekend using TurboTax and found the exact same thing. My taxes went up by approx. 300%! Very little has changed with my income the past 2 years. Last year I got a COLA raise and that's about it, so certainly my taxes should not have jumped so considerably. Nor did I change my withholding. It appears that with the tax "cuts" that were enacted last year, since I did not change my withholding, those cuts were not cuts at all but LOANS using fuzzy math! Very disappointing and I will be voting accordingly.
