What was he thinking??

My hubby I am so beyond frustrated with him.  I am trying to figure out why in the heck he never changed his number of dependents claimed at work for tax purposes?  He didn’t change them since we first got married!   Hello!  When our President did the tax decrease this past year and they took less out to help stimulate the economy that should of been a red flag.  I said something several times to him did he listen?  NO!  Even though he made  way less than previous years, we are talking about 30% less here, we are going to have to pay this year anyhow because he didn’t change that number!  For hours I sat last night and used two different programs, which now I don’t trust either one because both came up with two different amounts and not just a few dollars off.  I told him for this year I think we need someone to do our taxes for us.  I have a little income I need to claim as well which isn’t the issue in paying taxes. I have mine put away to cover it.  We still would get back from the state, its just the federal return.   What was he thinking??  Now he is all in a mood, hey I didn’t do it, it was something he did or didn’t do, not me!  So why do I have to take his moody comments about it?   I mean his son is 22 as of this month we haven’t been able to claim in in how many years?  Then there is the change with my daughter we can’t claim her either, that is a difference of two right there!    I don’t feel I should have to ride his ass on this stuff!  I assumed he was being responsible, he is the head of the house here!  I can’t do it for him!   I am not going to sit and stress over it either, I don’t feel I should have too!  I want so much to just yell at him but do you know what that would do?  Cause a huge argument between us!  So I can’t, nope I have to sit back and be the good wife and not say a word about it, if I did I be accused of not being supportive!  Not going there!  Just not going there!
