We used Craig Wear to determine whether a ROTH conversion made sense for us.
His firm is not an investment advisor, and he does not work on a commission. He does not recommend specific investments either.
He has written a book that is available at Amazon. It tells you a lot about the conversion process. For some people it makes no sense. For others like us, it made a lot of sense.
We are in year four of the process after 3 years of large conversions.
Wife and I both had large 401Ks that we first rolled over into conventional IRAs when we retired at 65.
We deferred our SS to gain that 8% return each year until we turned 70 last year. We had other taxable income from deferred compensation and taxable investment accounts that provided bulk of our income until we started SS.
We paid for a plan for ROTH conversions, and began conversion 4 years ago. It put us into a higher tax bracket, and we paid estimated taxes each year. We hit IRMAA, too, but wife had a retirement benefit that took care of that surprise.
Craig Wear developed a conversion plan for us that made sense. It worked for us.
Read his book as he fully describes the process, the planning, and it tells you whether it makes sense for your situation.
As for future taxes...who knows. I do know that the ROTH balances for us will NOT be taxed. Everything else will be.
