Thank you very much dmertz for your very helpful answer and your caution re 2019 marginal tax rate. My goal (if I can make it happen) is to get solar this year and make Roth conversions to utilize the solar tax credit. I will see how plans go before I convert much.
Is 85% the maximum amount of SS that the Federal govt will currently ever tax? Is that why you mention that percentage?
I was unaware of the What-If Worksheet, have found it, and am going through the Help pages to figure out how to use it. I suspect it could have saved me a lot of time yesterday in determining optimum Trad IRA vs. Roth contribution .
Thank you again!
