While hubby is deployed all of his income is considered tax-exempt on the federal level. (His "home of record" state does not have an income tax, so we're clear that way. Praise the Lord!) But his paycheck since being deployed in June was one big screw-up, it's almost comical how messed up it was. Only when he got really upset (think Drill Sergeant on Steroids) and threaten to notify our Congressman did it get fixed. So this month was a very nice paycheck for him--lots of back pay and taxes refunded. So hopefully that part of our taxes headache will be taken care of.
Military members can get their taxes done at the tax center on post by tax attorneys each year for free, so we always go there to get our taxes done. Since I worked this year and will have to pay taxes to the state where we live, it will be beneficial to us to see how that works--if we should file jointly and divide out our incomes or just file separately. That's something to ask the tax attorney.
If baby boy comes early, that will be another deduction!! (The Lord is in charge of that one, though...) 
We tithe regularly to our church and give to two charities which are near and dear to us. That helps with deductions. Our mortgage interest helps, too.
I have some items I need to donate to charity, but I doubt I will get around to doing that before the end of the year. We have never asked for a receipt with other donations, but now is as good a time as any to start that habit.
