Tax-Advantaged Accounts: IRAs, 401(k)s, and How to Use Them
Tax-advantaged accounts like IRAs and 401(k)s can save you thousands over your investing lifetime. Learn how each works and which to prioritize.
The Government Wants You to Invest
Through tax-advantaged accounts like IRAs and 401(k)s, the government essentially pays you to invest for retirement. The tax benefits β either upfront (traditional) or at withdrawal (Roth) β can mean hundreds of thousands of extra dollars over a career. Ignoring these accounts is leaving free money on the table.
401(k): Your Employer's Gift
A 401(k) is an employer-sponsored retirement plan. You contribute pre-tax dollars directly from your paycheck, reducing your taxable income for the year. The money grows tax-deferred β no taxes on dividends or capital gains while it's in the account. You pay ordinary income tax when you withdraw in retirement.
The killer feature: employer matching. If your employer matches 50% of contributions up to 6% of your salary, and you earn $60,000 and contribute $3,600 (6%), your employer adds $1,800 β that's an instant, guaranteed 50% return. Not contributing enough to get the full match is literally turning down free money.
2025 contribution limit: $23,500 (plus $7,500 catch-up if age 50+).
IRA: Individual Retirement Account
An IRA is an account you open yourself (not through an employer). Two main types:
- Traditional IRA β Contributions may be tax-deductible (depending on income and whether you have a workplace plan). Growth is tax-deferred. Withdrawals in retirement are taxed as ordinary income.
- Roth IRA β Contributions are after-tax (no deduction now), but all growth and qualified withdrawals are completely tax-free. This is incredibly powerful. $6,000/year invested from age 25 to 65 at 8% grows to about $1.5 million β and you pay zero tax on any of it.
2025 contribution limit: $7,000 ($8,000 if age 50+). Income limits apply for Roth IRA eligibility.
The Optimal Order of Operations
- 401(k) up to the employer match β Get that free money first. Always.
- Max out Roth IRA β Tax-free growth is the best deal in investing.
- Back to 401(k) to max it out β If you still have money to invest after steps 1 and 2.
- Taxable brokerage account β Only after you've maxed your tax-advantaged space.
HSA: The Triple Tax Advantage
If you have a high-deductible health plan, a Health Savings Account (HSA) offers the best tax treatment of any account: contributions are tax-deductible, growth is tax-free, and withdrawals for medical expenses are tax-free. After age 65, you can withdraw for any reason (paying ordinary income tax, like a traditional IRA). It's worth maxing out if you're eligible.
Key Takeaways
- Never leave employer match money on the table β it's an instant, guaranteed return.
- Roth IRAs offer tax-free growth and are the most powerful retirement account for most young investors.
- Prioritize: 401(k) match β Roth IRA β max 401(k) β taxable brokerage.
