A $500K IRA + $300K 401(k) = Two Separate RMD Calculations

A $500K IRA + $300K 401(k) = Two Separate RMD Calculations

The IRS lets you aggregate some RMDs but not others — a mistake could trigger penalties

The Details

You can satisfy all traditional IRA RMDs from just one IRA, but if you have three 401(k)s from different employers, you need three separate withdrawals. Many retirees accidentally aggregate 401(k) RMDs like they do with IRAs.

What this means for you

Retirement decisions compound — getting one of these details wrong can cost tens of thousands of dollars over a retirement. The good news: most of these mistakes are completely avoidable if you understand how the rule actually works.
