Spent the last few months modeling my own retirement transition (I retire from sea duty in January) and one thing surprised me. Almost every planning conversation I had — with advisors, with peers, in the books I read — started with asset allocation. Stocks vs. bonds. Equity glide paths. Risk tolerance. Then "asset location" got mentioned at the end like an optional bonus topic.
I think the order is backward.
Here's what I mean. Take two retirees. Same $1.5M. Same 60/40 split. Same picks even.
Retiree A holds bonds in a taxable brokerage and stocks in their IRA. Retiree B does the opposite — bonds in the IRA, stocks in the brokerage.
Over 20 years, the gap between those two outcomes runs into six figures of after-tax wealth. Same allocation. Same returns on paper. Different result.
Why?
Bond interest is taxed as ordinary income. Hold bonds in a taxable account and you're paying your top marginal rate on the coupons every year. Hold those same bonds in an IRA and the interest compounds tax-deferred until you withdraw.
Stocks held in a taxable account get long-term capital gains treatment when you sell, currently 0/15/20%. Qualified dividends get the same friendly rates. Hold them until death and your heirs get a step-up in basis.
Stocks held in a traditional IRA convert all that favorable capital gains potential into ordinary income on the way out. Worse, RMDs at 75 force distributions whether you need them or not. The faster the asset grows in the wrong account, the larger the eventual tax bill.
The framework most retirees end up at:
- Roth: highest-growth assets (small caps, growth equities, anything with the longest runway)
- Traditional IRA / 401(k): bonds, REITs, anything tax-inefficient
- Taxable brokerage: tax-efficient index funds, individual stocks held long term, munis if you're in a high bracket
Allocation determines the risk you're taking. Location determines how much of the return you actually keep.
Anyone else worked through this exercise on their own portfolio? Curious how others have structured the three buckets, and especially how people are handling Roth conversions if they've got mostly pre-tax money.
