Two portfolios with identical holdings can produce different after-tax results — not because of what they own, but because of where they own it. This is where the concept of asset location becomes important.
Asset location is placing specific investments in specific account types for tax purposes. The idea is straightforward: match each investment to the account where it's taxed least. Done well, research from Vanguard and others suggests it can add roughly 0.75% per year in after-tax returns.
The conventional playbook: put bonds and other income-heavy investments in tax-deferred accounts like 401(k)s and IRAs, where that income isn't taxed annually. Keep high-growth investments in taxable accounts, where long-term gains rates are lower, and in your Roth, where they benefit most from tax-free compounding.
However, follow that playbook too rigidly and you can end up with tax-advantaged accounts that are too conservative — mostly bonds — while your taxable account is mostly equities. The accounts with the longest time horizon end up capped by fixed-income returns. And if you need cash from your taxable account, you're selling stocks — possibly during a drawdown.
Before locking in a location strategy, it's worth simulating the results — both near-term liquidity needs and long-term growth targets. Tax efficiency should improve a portfolio, not reshape it.
