Jumping back into the fray... was out most of the day, but appreciate everyone's responses. Yes, 1st world problems.
While not perfect, I ran a few analysis on NewRetirement Planner Plus. While it's not perfect, is does use the current tax code and deductions (adjusts them annually by an inflationary factor I believe) and allows you to run some what if scenarios.
1) My Baseline Assumptions/Results
- Retirement withdrawals start age 56, 1/1/21, based on spending needs/wants/wishes
- RE accts split 50/50 after tax and 401K (no current Roth, all RE income from assets)
- SS starts age 70 (no pensions, other income)
- Steady annual expenses growing annually by inflation, all brokerage & 401k accts grow 5% year.
- Uses 100% after tax accts until RMDs hit, taxes stay very low (only State and capital gains) until 72 at which point RMDs have me consistently hitting 32% - 35%, +/- double NW at end of life. This would feel great until 72, but also feels like I am just kicking the can the road... kinda like or Fed government!
2) My Baseline Assumptions + 401K Withdrawals
- 15 years (thru age 71) of equal amount 401K withdrawals (represents +/- 56% of Yr 1 planned spend)
- Lifetime taxes drop 13% from Baseline
- Top tax bracket 22% until RMDs, then 24% until last 2 yrs of life when it hits 35%. This "feels" ok to me and solves part of the problem similar to Roth, but it appears it does not go quite as far?
3) My Baseline Assumptions + Annual Roth Conversions
- 15 years (thru age 71) of equal amount Roth Conversions (represents +/- 56% of Yr 1 planned spend, same amounts as used for 401K withdrawals)
- Lifetime taxes drop 17% from Baseline
- Top tax bracket 22% until RMDs, then 24% until last 2 yrs of life when it hits 35%. Ok, maybe...
4) My Baseline Assumptions + 3 Yrs Large Roth Conversions
- First 3 Yrs equal large Roth conversions, totaling the 15 yrs of Roth conversions noted above (I would have done 1 big Roth conversion, but calculator will not let you model a 7 figure conversion)
- Lifetime taxes drop 22% from Baseline
- Top tax bracket 37% first 3 yrs, then low (capital gains and state tax) until RMDs, then 24% until last 2 yrs of life when it hits 35%. This feels drastic, but wondering if swallowing the pill upfront helps avoid the slow bleed!
Of course a dollar today is worth more than a dollar in the future, so the savings in today's dollars on lifetime taxes is arguably less than the above.
I suppose I should give more thought to the surviving spouse tax hit as well. Ideas of maybe leaving partial tax differed accounts to kids another idea, but that also passes on a tax liability to them. Again, not complaining, just contemplating...
