Can you tell me why my taxes owed went from $1600 to $2900 when my income went down, my withholding has not changed and my deductions are basically the same as last year?

You'd really need to look at 2017 and compare the figures against 2018 to see what changed......itemized deductions did have some changes, the state and local property taxes category is capped off at 10,000 now....that may have caused you to lose a considerable amount of deductions, or if you had unreimbursed employee business expenses in the past, those were taken away as well for 2018.

most peoples withholding DID go down, even if they didn't initiate any changes....so you may want to double check Box 2 on each years W2s

No one on Answer Xchange can see your tax return. Some people are saying “Nothing has changed from last year.”  That is not true.  There are major tax law changes that have begun with this tax year.  Personal exemptions of over $4000 per person were removed.

 One thing that may be affecting your refund for 2018 is that employers began withholding less tax when the new tax law passed.  Your paychecks were more, but that means a smaller refund now.  

There are are lot of variables that affect your refund or tax due including how much you earned, how much tax you had withheld, your filing status, the number of dependents you claim, your deductions and credits, etc.  You may have lost Earned Income Credit or the Child Tax Credit— did a child turn 17?  If you received the EIC last year, remember that changes in the amount you earn have a big effect on the amount of EIC you can get. (Sometimes earning more money means less EIC)  Are you 65 or older ?  If so, your standard deduction is higher. Everyone has a higher standard deduction now so it is harder to use itemized deductions.  Or do you have a healthcare penalty?  We used to be able to suggest comparing two years of tax returns side by side to find the differences.  But with the drastic change in the 2017 and 2018 forms, that is tricky this year. Another thing to compare is the amount withheld for federal tax in box 2 of your 2018 W-2 with the amount withheld for 2017.

And of course, always check your own data entries, looking for errors such as misplaced decimals or extra zeros.
