What is asset location?
Last updated August 2026
Short answer
Asset allocation decides what you own. Asset location decides where you keep it. The second question is easier, entirely within your control, and almost universally ignored.
Three kinds of account, three tax treatments
Taxable brokerage. Dividends and interest taxed annually, gains taxed on sale. Fully flexible, no limits, no penalties.
Tax-deferred, meaning a traditional 401(k) or IRA. Nothing taxed along the way, everything taxed as ordinary income on withdrawal.
Tax-free, meaning a Roth account or an HSA used for medical costs. Nothing taxed along the way and nothing taxed on qualified withdrawal.
Because the three treat income differently, the same holding produces a different after-tax return depending on where it sits.
The ordering principle
Put the assets that generate the most annually taxed income where that income is sheltered.
Bonds and bond funds pay interest taxed at ordinary rates every year. REITs distribute mostly ordinary income. Actively managed funds with high turnover distribute realized gains. All three are expensive to hold in a taxable account.
Broad equity index funds and most equity ETFs distribute small qualified dividends and rarely pass through capital gains, so most of their return is deferred until you choose to sell. They are cheap to hold in a taxable account.
What belongs where
Tax-deferred accounts: taxable bonds and bond funds, REITs, high-turnover active funds, anything with a high ordinary-income yield.
Roth and HSA: the assets with the highest expected long-run growth, because growth there is never taxed at all. That argues for equities rather than bonds in a Roth, which is the opposite of what many people do.
Taxable: broad equity index funds and ETFs, individual stocks held long term, and municipal bonds, whose exemption is wasted anywhere else.
The counter-argument worth knowing
Putting bonds in the tax-deferred account and equities in the Roth means the Roth is expected to grow faster, and a tax-deferred account that grows slowly produces smaller taxable withdrawals later.
Some argue the opposite: that holding higher-growth assets in the tax-deferred account and accepting the eventual ordinary-income tax is fine, because the government effectively shares the downside too.
Both positions are defensible. What is not defensible is holding a high-yield bond fund in a taxable account while an equity index fund sits in the IRA, which is the arrangement asset location exists to prevent.
Foreign holdings are the exception
International funds pay dividends subject to foreign withholding tax. Held in a taxable account you can generally claim a foreign tax credit and recover it.
Held inside an IRA there is no US tax to credit it against, so the withholding is simply lost, typically a fraction of a percent of the holding each year.
That is a genuine argument for keeping international equity in a taxable account, and it runs against the usual instinct to shelter everything possible.
Try it in Walnut
Walnut reads your connected brokerage accounts and shows the holdings together, which is what makes it possible to see whether your income-heavy assets are in the wrong place.
It only works if you keep the allocation intact
Location decisions must not become allocation decisions. If you want 30% bonds, you want 30% bonds across everything you own, not 30% inside each account.
That means the accounts will look unbalanced individually, and that is correct. Judging the IRA on its own after moving all the bonds into it is a misreading.
Rebalancing then happens across the whole portfolio, ideally inside the sheltered accounts where trades cost nothing in tax.
How much it is actually worth
The benefit scales with how much you hold in taxable accounts, your marginal rate, and how much of your portfolio is in tax-inefficient assets.
Someone whose savings are entirely in a 401(k) gets nothing from this, because there is only one account. Someone with a large taxable account and a high marginal rate gets the most.
It is not a large annual number, but it is free, permanent, and requires no view on markets. That combination is rare enough to be worth an afternoon.

FAQ
What is asset location?
+
Deciding which of your accounts holds which investment, so heavily taxed assets sit in sheltered accounts and lightly taxed ones sit in taxable accounts. It improves after-tax return without changing what you own, your allocation or your risk.
Should bonds go in a taxable account or an IRA?
+
Taxable bonds generally belong in a tax-deferred account, because interest is taxed annually at ordinary rates and compounds untouched inside an IRA. The exception is municipal bonds, which are already tax exempt, so sheltering them wastes the exemption.
What should I hold in a Roth IRA?
+
Typically the assets with the highest expected long-run growth, because growth in a Roth is never taxed. That argues for equities rather than bonds, which is the opposite of how many people use the account.
Should international funds go in a taxable account?
+
Often yes. Foreign dividends are subject to withholding tax, and in a taxable account you can generally claim a foreign tax credit to recover it. Inside an IRA there is no US tax to credit it against, so the withholding is lost.
