Why is asset location such a sticky wicket? For one thing, the tax treatment of investments
changes frequently, so what may be an optimal asset placement today may not be a few years
from now. Dividends provide a great case in point. Prior to 2003, income from stock dividends
was taxed at the ordinary income tax rate, so you'd generally want to hold income-rich stocks
in your tax-sheltered accounts.
But when dividends began to be taxed at the lower, capital-gains tax rate, they were no longer
verboten for taxable accounts. As the currently low dividend-tax rates are set to expire at the end
of this year, dividend-tax treatment is again up for grabs, so I'd be hard-pressed to recommend
that you hold dividend payers in your taxable accounts until there's some clarity on the issue.
In addition to tax treatment confusion, practical considerations sometimes completely contradict advice that makes good tax sense. Most of us naturally use our retirement accounts (401(k)s and other company-retirement plans and IRAs) as a storehouse for our longest-term savings, so it's only logical that we'd be inclined to invest in long-term assets (namely, stocks) there.
Meanwhile, from a practical standpoint it's logical to want to hold more safe, stable, and liquid assets (namely, bonds and cash) in accounts that we can readily tap without strictures or penalties--our taxable accounts. Yet as much logical sense as those asset-placement arrangements might seem to make, they precisely contradict what a tax advisor would tell you to do. Because income from bonds and cash is taxed at your ordinary income tax rate, that's a powerful argument for holding bonds in your tax-sheltered accounts while keeping at least some stocks in your taxable account.
So how should you navigate this confusing landscape? There are no one-size-fits-all solutions, and it's worth revisiting your asset-location framework every few years, to make sure your plan syncs up with the current tax rules. But here are some general guidelines.
Hold in Your Tax-Sheltered Accounts: High-Returning Assets with High Tax Costs
Because you don't have to pay taxes from year to year on income or capital gains you earn in tax-sheltered accounts like IRAs and 401(k)s, these are good receptacles for higher-returning investments that also have heavy tax consequences. The best example would be junk bonds, junk-bond funds, and multisector-bond funds, all of which kick off a high percentage of taxable income. And while it's a stretch to call high-quality bonds and bond funds "high-returning" right now, they're also a better fit for tax-sheltered accounts than for taxable because their payouts are taxed at an investor's ordinary income tax rate.
So generally speaking, to the extent that you hold bonds, you're better off doing so within the confines of a tax-sheltered account. If you need to hold bonds in your taxable accounts, use the tax-equivalent yield function of Morningstar's Bond Calculator to determine whether a municipal bond or bond fund might offer you a better aftertax yield than a taxable bond investment.
