What is asset location and how does it fit into tax planning?

Asset location is the decision about which type of account holds which asset class. Asset allocation sets the portfolio's risk-return mix; location optimizes its after-tax outcome.

The general principle: place tax-inefficient assets in tax-advantaged accounts (IRAs, 401(k)s) and tax-efficient assets in taxable accounts.

Tax-inefficient = generates substantial ordinary income or short-term capital gains:
- Taxable bonds (interest is ordinary income)
- REITs (most distributions are ordinary)
- Actively managed funds with high turnover
- TIPS (inflation adjustments taxed as phantom income)

Tax-efficient = low ordinary income, gains are long-term or deferred:
- Broad-market equity index funds (mostly qualified dividends, deferred gains)
- Municipal bonds (interest federally tax-exempt; redundant in a Roth or traditional account)
- Individual stocks held long-term
- ETFs with low turnover

A concrete example: Anisa Lavelle has $1M split equally: $500K in a taxable account, $500K in a traditional IRA. Her target allocation is 60% equity / 40% bond. Naive allocation holds 60/40 in each account. Optimal asset location:

- IRA ($500K): 100% bonds ($500K of bond exposure)
- Taxable ($500K): 80% equity ($400K) + 20% munis ($100K)

Result: total $600K equity / $400K bond, same 60/40. But bond interest accrues tax-deferred in the IRA, equity gains are deferred and eventually taxed at long-term rates, and the small bond sleeve in taxable is municipal (tax-exempt). Over 20 years this can add 30-80 bps of after-tax return.

Edge cases: Roth accounts should hold the highest-expected-return assets (equity, aggressive growth) because gains are never taxed. Municipals should never be in a tax-deferred account — the exemption is wasted.

CFA exam: distinguish asset allocation (total risk exposure) from asset location (which account holds what). The latter is a tax-alpha decision.
