Glen's Verdict

Former hedge fund manager, current index fund enthusiast

Always max tax-advantaged accounts first, then overflow into taxable. The priority order: 401(k) up to employer match → HSA max → Roth IRA max → 401(k) max → taxable brokerage. The tax-deferred or tax-free compounding in sheltered accounts is worth tens to hundreds of thousands of dollars over a career. Taxable accounts are the overflow valve — excellent when you have wealth that exceeds the tax-sheltered limits, but never your first dollar invested.
