Because RMDs are forced taxable income, they can push retirees into higher brackets and trigger knock-on effects — higher Medicare premiums through IRMAA, and more of your Social Security becoming taxable. Planning ahead matters more than most people realize, and the best window is the years between retiring and the RMD start age.
Two strategies stand out. Roth conversions during low-income years move money out of the RMD-generating pool permanently, since Roth IRAs have no lifetime RMDs. And qualified charitable distributions (available from 70½) let you send IRA money directly to charity — it satisfies the RMD without being included in taxable income, which is usually better than donating after taking the distribution.
