The back story.
We are very fortunate and this is not a post about complaining about how much we pay in taxes, but it has tax implications.
My wife and I have been going back and forth about contributing to her 457 plan for most of this year. She says she would rather have the money in the bank but I would love to get our taxable income down. The last couple years we've owed $3000-4000 to the IRS even with buying a house ($140k, 3%/15yr, barely any interest + should be paid off by Dec.), having a child, maxing my tIRA (no 401k for me). She has a pension offered through her job, so she can't do a tIRA but I do have a Roth for her. She already has a mandatory 11% contribution to her pension, so she doesn't want to "save too much for retirement when she could die tomorrow".
The new "problem" this year is her employer caught up on back pay that was owed and it will raise our taxable income by ~$15k and I've been working overtime this year to add to the 'stache, so our taxable is going up by $30-40k this year (estimated). This will likely put us above the tIRA phase out and we will lose another ~$1400 deduction. According to the W-4 worksheet, we should both be claiming Single/0/+$25 per week.
My wife is good about living within her means but she doesn't understand finance for the most part. I've taught her about interest/the dangers of CCs/etc, but I can see her eyes glaze over when I start talking about compounding, tax deferment, investing, inflation, etc.
I'm mainly looking for ways to convince her to start contributing to her 457 plan since we don't "need" the money right now. Come December we will literally have $0 debt (no mortgage/CCs/car payments/nothing). So, not deferring the max of our income right now is incredibly shortsighted, especially when the cash will sit in the local bank savings @ .25% interest.
Anyone have any magic bullets?
