Asset Location
Why, once you have both taxable and tax-advantaged accounts, it can matter which investments you hold in each, what research suggests, a worked example, and the practical limits of the idea.
The short version
Asset allocation is how your money is split between stocks, bonds, and cash. Asset location is which account each piece sits in. Because a taxable account is taxed each year on interest and dividends, and on gains when you sell, investments that produce a lot of regular income, such as taxable bond funds, are generally better sheltered in tax-advantaged accounts, while tax-efficient ones, such as broad index funds, can sit in a taxable account. Research finds that placing assets this way can improve after-tax results. Look at your allocation across all accounts together, and keep money you may need soon where you can reach it.
By the end of this lesson, you'll be able to
- Distinguish asset location from asset allocation
- Explain which kinds of investments are tax-efficient and which aren't
- Work out the yearly tax difference between two ways of placing the same portfolio
Why this matters
This optional lesson is for anyone with money in more than one kind of account, such as a 401(k) and an ordinary brokerage account. Once you have both, the same portfolio can be arranged in different ways, and some arrangements leave more for you after tax than others. It's a refinement, not a foundation: get the allocation right first.
Allocation and location
Asset Allocation decides how your money is split between stocks, bonds, and cash. Asset location. Choosing which kind of account, taxable or tax-advantaged, to hold each investment in, to reduce the taxes you pay overall. Glossary decides where each part is held: in a taxable account, a tax-deferred account such as a traditional 401(k), or a Roth account. The allocation stays the same; only the placement changes.
How investment income is taxed in a taxable account
- Interest from bonds and savings is generally taxable each year as regular income.1 Interest on bonds issued by state and local governments generally isn't taxable.1
- Dividends are taxed each year. Ordinary dividends are taxed as regular income; qualified dividends are taxed at the lower capital gains rates.2
- Gains are taxed when you sell, and the rate on most long-term gains is no higher than 15% for most people.3 Funds can also pay out the gains from their own sales as a Capital gains distribution. A payment a fund makes to its shareholders from profits on investments it sold. In a taxable account, it's generally taxable even if you didn't sell anything. Glossary, which is taxable even if you never sold a share.4
Inside a tax-advantaged account, none of this is taxed year to year. So the shelter is worth the most for investments that would otherwise produce the most taxable income each year.
What research suggests
A study by John Shoven and Clemens Sialm found that, for an investor saving for retirement, taxable bonds have a preferred location in the tax-deferred account, and tax-exempt municipal bonds belong in the taxable account for investors in high enough tax brackets. Tax-efficient stock funds, such as passively managed ones, were better held in the taxable account, and tax-inefficient, actively managed stock funds in the tax-deferred account. Locating assets this way, the authors found, can significantly improve risk-adjusted results.5
| Investment | Why | Tends to fit best in |
|---|---|---|
| Taxable bond funds | Interest is taxed each year as regular income | Tax-advantaged accounts |
| Actively managed stock funds | Frequent selling can pass taxable gains to you | Tax-advantaged accounts |
| Broad stock index funds | Mostly qualified dividends and few realized gains | Either; often the taxable account |
| Municipal bonds | Interest is generally already free of federal tax | Taxable account, if held at all |
General tendencies, not rules. Individual funds differ, and so do tax situations.
