Max tax-advantaged accounts before taxable investing

Use 401(k), IRA, and HSA contribution room fully before opening a taxable brokerage account.

Why it works

Tax drag — the annual return cost of capital gains, dividends, and distributions in taxable accounts — compounds silently over decades. A tax-advantaged account eliminates or defers this drag, which mathematically compounds into a substantial advantage over 20–30 year horizons. The order of operations matters more than fund selection at most income levels.

How to do it

1. Contribute at least enough to your 401(k) to capture any employer match — this is an immediate 50–100% return.
2. Fund a Roth or traditional IRA next (choice depends on current vs. expected tax bracket).
3. If eligible, fund an HSA third — it is the only triple-tax-advantaged account available.

Evidence

The mathematics of tax-deferred and tax-free compounding are arithmetic, not contested. At common long-term capital gains and income tax rates, tax-advantaged accounts reliably produce meaningfully higher after-tax outcomes over 20+ year horizons. (mechanistic)

Tax laws change; the ordering heuristic is accurate under current U.S. law and may differ in other jurisdictions or if tax policy changes significantly.

Common mistake

Opening a taxable brokerage account before maxing tax-advantaged room — particularly skipping the employer match, which is the only guaranteed immediate return in personal finance.
