The Supercharged Sidedoor Roth—High income workers cannot participate in traditional Roth conversions, given their low limits (around $196k in income). The Supercharged Sidedoor Roth converts qualified retirement funds such as 401(k)s and IRAs into tax- free income by creating a Roth conversion, subsidized by the plan. In other words, the conversion creates a taxable event, but with few out-of-pocket expenses or loss of principal.
