Understand how spreading a Roth conversion over multiple years changes educational tax estimates.
A multi-year conversion schedule spreads a total planned conversion amount across more than one tax year. This can change which brackets are reached in each modeled year.
Equal-split schedules are easy to understand, but they are not automatically optimal. Real planning may use income windows, tax-law changes, RMD timing, or cash-flow needs.
Use multi-year comparisons to see how assumptions behave, then verify the actual plan with a professional who can model your complete tax return.
