The Critical Importance of Asset Coordination in Retirement Planning

Conventional wisdom dictates that retirees maximize income and minimize taxes by withdrawing assets from their taxable accounts first, their tax-deferred accounts (e.g., traditional IRA, 401(k)) second and their tax-exempt accounts (such as a Roth IRA) third.

But just because it’s conventional doesn’t mean it’s wise. A large percentage of the taxable account is its basis, or a return of principal, and therefore not taxed. Consider a retiree who has yet to reach age 70½ and therefore not yet subject to required minimum distributions. He might be in a 10% or 15% tax bracket in his taxable accounts. But once RMDs begin, he’ll jump to 25%.

In early retirement years, he should withdraw funds from tax-deferred accounts to take full advantage of the 15% tax bracket. But that raises the question—why not withdraw from a taxable account since the majority of assets are tax-free anyway? Because he blows the opportunity to withdraw from the tax-deferred account at the 15% (or lower) rate. It’s better to pay 15% before 70½ than to take these withdrawals after and pay the higher 25%.   

The correct sequence would therefore be to take tax-deferred income first and withdraw any additional funds needed from his taxable accounts. After the taxable account is exhausted, he can continue to take tax-deferred income at the 15% bracket and withdraw any additional needed funds from his tax-exempt account.  

Such tax-efficient withdrawal strategies can only be done by coordinating each account and asset in the retirement portfolio, and this includes Social Security. Is coordination complicated? Yes, but proper instruction and software are here to help.
