DH and I just ran the numbers through H&R Block software, married filing jointly. Last year, we received a ~$2K refund, so we ran a W4 calculator and adjusted his withholdings by 1. This year, we currently owe $1,720... and also get hit with a $29 underpayment penalty. :-( Our taxable income increased about $8K, and everything else was largely the same. Like last year, we both maxed out our Roth IRAs and traditional 401(k)s (TSPs). (This is our fifth year of Roth contributions, so the plan was to switch to traditional this year anyway; when I started investing 5 years ago, I liked the Roth benefit of being able to withdraw contributions after five years as a backup emergency fund.) Our current AGI is about $68K, which means we're $7K too high to receive the Saver's Credit ($400) either (must be under $61,500 AGI). So we're considering recharacterizing both of our Roth IRA contributions ($11K total) to traditional to 1) get us under the $61K AGI to get the $400 Saver's Credit, and 2) receive a $330 refund instead of owing $1,720 (difference of $2,050).
Now, this would be a $2K difference this tax year, but how does that affect us in the future? It looks like we earned about $1,800 on our $11K of contributions, so that would also have to get recharacterized. That $1,800 invested at 8% over 33 years (now until 65) could come to about $22,400. Estimate 15% taxes on those gains when we withdraw at retirement age, and we're looking at $3,360. But that's future dollars (33 years out), which is less valuable than today's $2,050, right? Also, we plan to FIRE in about 10 years at 42 when DH hits his 20-year mark in the military. So at that point, we would likely do a Roth Conversion Ladder, which would decrease the amount of time/gains this money would have in the traditional account to be taxed.
So, the questions are- 1) Does my math look right? 2) Am I missing anything to consider? 3) What do the fine minds of the MMM community recommend (recharacterize both, neither, or one plus some to get under $61,500 AGI)? 4) Do we need to wait for the Vanguard recharacterization to be fully processed and receive the new forms before we file, or can we file as though we made the contributions to the Traditional and submit this weekend? We're expecting baby #1 in the next 1-3 weeks, so we want to file before she arrives and we become perpetually sleep deprived. :-) TIA!
