When you retire, one of the first things you’ll be asked is what to do with your 401(k). Most people assume the answer is automatic: roll it into an IRA. It’s simple, familiar, and often the right move. But like most “obvious” financial decisions, a little forethought can go a long way, because once you roll over, you can’t roll back.
A rollover isn’t just a transfer. It’s a pivot point in your financial life, one that affects taxes, timing, and flexibility for years to come. For example, keeping money in your employer’s 401(k) after you retire can sometimes allow you to delay required minimum distributions (RMDs), especially if you’re still working past your early 70s. Moving those funds to an IRA, by contrast, can trigger RMDs sooner.
There are also tax-planning opportunities inside many 401(k)s that disappear after a rollover. Some plans include after-tax subaccounts that can be strategically moved into a Roth IRA via a “mega backdoor Roth.” Others hold employer stock eligible for favorable long-term capital gains treatment under the Net Unrealized Appreciation (NUA) rules. In both cases, a well-timed move can save thousands in future taxes. A hasty rollover can erase those options entirely.
That’s why “thinking before you roll” isn’t about hesitation, but rather coordination. The right strategy might involve rolling part of your account to an IRA for investment flexibility, while keeping another portion in the 401(k) to preserve key benefits or delay RMDs.
At this stage of life, the small details matter. A few extra minutes of review now can prevent years of unnecessary taxes later, and help ensure your retirement income plan starts on the right foot.
