Yes, but as a different problem. Retired, with pension, and drawing Social Security, and still converting into Roth. The amount of conversion could affect the premium you pay for Medicare. Pension (or annuity income) automatically makes Social Security 85% taxable. So same problem, different verse.
I choose to convert small amounts to Roth to chip away at the RMD amounts, and take the Medical deduction to reduce tax burden. The taxable Social Security doesn't really net out to 85% of the payment, but, like everything else, it is what it is.
Only got A dimple, would have preferred 2!
