Conclusion

Choosing the right investment accounts is a critical component of building long-term wealth. The optimal strategy typically involves maximizing tax-advantaged accounts in priority order (HSA, 401(k) match, Roth IRA, 401(k) max) before using taxable accounts. Consider your current and expected future tax rates, time horizon, and specific goals when deciding between Traditional and Roth options. Proper asset location across account types can further enhance your after-tax returns.
