Why Tax-Advantaged Accounts Matter

The U.S. offers special accounts that reduce or defer taxes on investment growth. Using them can significantly boost your long-term returns. Money that would otherwise go to taxes stays invested and compounds. Over decades, that difference can be substantial.

The main types are:

  • 401(k) — Employer-sponsored. Often includes a match. Contributions reduce your taxable income.
  • Traditional IRA — Tax deduction now, taxed when you withdraw in retirement.
  • Roth IRA — No deduction now, but withdrawals are tax-free in retirement (if rules are followed).

401(k) — Start Here If You Have Access

If your employer offers a 401(k), this is usually your first stop. Many employers match a portion of your contributions—e.g., 50% of the first 6% you contribute. That's free money. Not contributing enough to get the full match is like leaving money on the table.

Contribution Limits (2025)

  • Under 50: $23,000 per year
  • 50 and older: $30,500 (catch-up)

Contributions reduce your taxable income. If you earn $60,000 and contribute $6,000, the IRS taxes you on $54,000.

Traditional vs Roth 401(k)

Some employers offer both. Traditional reduces taxes now; Roth means you pay tax now but withdraw tax-free later. If you're early in your career and expect a higher tax bracket in retirement, Roth can make sense. When in doubt, a mix of both works.

Traditional IRA vs Roth IRA

IRAs are individual accounts you open at a broker. They're separate from your 401(k).

Roth IRA Income Limits

Roth IRA has income limits. In 2025, if you're single and earn above ~$161,000 (or married filing jointly above ~$240,000), you may not be able to contribute directly. High earners sometimes use a backdoor Roth—contributing to a Traditional IRA and converting to Roth. This requires care; consult a tax professional.

IMPORTANT

Roth IRA has income limits. High earners may need to use a backdoor Roth. Consult a tax professional for your situation.

The Order of Operations

A common strategy:

  1. 401(k) up to employer match — Free money first. Never skip this.
  2. Max Roth IRA (if eligible) — Tax-free growth is powerful. $7,000/year adds up.
  3. Max 401(k) — More tax-deferred space. After the match, fill this before taxable.
  4. Taxable brokerage — For anything beyond. Still great; you just pay taxes on gains.

Example

Sarah earns $70,000. Her employer matches 50% of the first 6% she contributes. She contributes $4,200 (6% of $70,000) to her 401(k)—her employer adds $2,100. She also contributes $7,000 to a Roth IRA. Total invested: $13,300, with $2,100 of that free.

Where should you invest first if your employer offers a 401(k) match?
