I got married this past year. Happy with the result, lead to a $4k refund(wife's ok too I guess
). We got the refund primarily because we had been withholding as single most of the year but switched to married at the end.
Not sure how I'm going to "use" it, since I don't normally believe in spending money just because you have it.
I ran some numbers, we could pay off out mortgage by April 2017 if I wanted. I could put it towards that, however I think we're looking at making a move to our "family house" sometime next year as well, so I don't think it's worth it(the bulk of that comes from money separate from our return anyway, just ruling out mortgage pay down as an option).
Overall, we're set in terms of retirement/emergency fund. I maxed out my 401k last year, probably will do the same again this year, she currently does a bit more than the company match on a 403b, so we could increase that if we wanted(however we preferthe flexibility at the moment). We don't qualify for IRA options other than possibly a back door conversion, but ultimately I think we're ok on saving for retirement.
So since emergency fund is set, retirement contributions are solid, we have no debt beyond the mortgage, I'm currently leaning towards a honeymoon level 1 year anniversary trip.
