FYI: Taxes are the major reason. The amounts that people who are age 70 1/2 or older must begin withdrawing from their tax-deferred accounts can push them into higher marginal tax rates than in the pre-RMD period, and can also increase the percentage of their Social Security benefits that are taxable.
But there's another complaint I've heard about RMDs: that these mandatory withdrawals could lead retirees to prematurely deplete their assets if it turns out that their RMDs were too rich, especially if they live way longer than the "average" life expectancies that underpin the IRS' tables for RMDs. Required minimum distributions start at a comfortable 3.6%, but ramp up to 5.3% at age 80 and are at 6.8% at age 85.
