A Roth IRA is one of the most powerful retirement accounts available. You contribute after-tax money, it grows tax-free, and you withdraw tax-free in retirement. For most young investors, it should be a top priority after getting the full 401(k) match.
Why a Roth IRA?
The magic of a Roth IRA is tax-free growth. If you invest $7,000 today and it grows to $70,000 over 30 years, you pay zero taxes on that $63,000 gain. With a traditional IRA or 401(k), you'd owe taxes on every dollar you withdraw.
Roth IRAs also offer more flexibility: you can withdraw your contributions (not earnings) at any time without penalty. This makes it a backup emergency fund if absolutely needed.
Eligibility and Limits (2024)
Key Numbers
- Contribution limit: $7,000/year ($8,000 if age 50+)
- Income limit (single): Phase-out starts at $146,000, fully phased out at $161,000
- Income limit (married filing jointly): Phase-out starts at $230,000, fully phased out at $240,000
- Deadline: Tax Day of the following year (typically April 15)
If your income is above the limits, you may still be able to contribute via a "backdoor Roth IRA" (contribute to a Traditional IRA, then convert to Roth). Consult a tax professional for this strategy.
The 5-Year Rule
To withdraw earnings tax-free, two conditions must be met:
- You must be 59½ or older
- The account must be at least 5 years old (from your first Roth contribution)
This is why starting early matters—even a small contribution opens the 5-year clock.
Step-by-Step: Opening a Roth IRA
- Choose a brokerage. Fidelity, Schwab, and Vanguard are all excellent. All offer $0 minimums and $0 trading fees.
- Create an account. Select "Roth IRA" as the account type. You'll need your SSN, address, and employment info.
- Designate beneficiaries. Who gets the account if you pass away? Don't skip this step.
- Link your bank account. Set up ACH transfer for funding.
- Fund the account. Transfer your first contribution (up to $7,000 for 2024).
- Choose investments. A target-date fund matching your retirement year is a simple, solid choice.
- Set up automatic contributions. Even $100/month adds up to $1,200/year automatically invested.
What to Invest In
For most people, these are the best options:
- Target-date fund: Pick the fund closest to your expected retirement year (e.g., Target 2055). It automatically adjusts from aggressive to conservative as you age.
- Total market index fund: Something like FXAIX (Fidelity), VTSAX (Vanguard), or SWTSX (Schwab) gives you broad U.S. stock exposure.
- Three-fund portfolio: U.S. stocks + international stocks + bonds in a ratio like 60/30/10.
Common Mistakes
- Funding but not investing. Money in a Roth IRA isn't automatically invested. Make sure to buy funds after depositing.
- Waiting until Tax Day. Contribute early in the year to maximize time in the market.
- Not contributing at all because you can't max out. Even $50/month is better than $0.
- Over-contributing. Track your contributions carefully. Excess contributions incur a 6% penalty annually until corrected.
Roth IRA vs Traditional IRA
Choose Roth if: You expect to be in a higher tax bracket in retirement, you want tax-free withdrawals, or you value flexibility.
Choose Traditional if: You need the tax deduction now, you expect to be in a lower tax bracket in retirement, or your income is too high for Roth.
Still not sure? For most people under 40, Roth is usually the better choice.
