Key Takeaway
The Roth IRA is the single best account for most young earners. You contribute after-tax dollars, your money grows completely tax-free, and withdrawals in retirement are tax-free. Open one at Fidelity or Vanguard today.
If you only open one investment account in your 20s or 30s, make it a Roth IRA. The tax advantages compound over decades into a genuinely life-changing amount of money. Here is everything you need to know to get started.
What Is a Roth IRA?
A Roth IRA (Individual Retirement Account) is a tax-advantaged investment account that you open and manage yourself, separate from any employer plan. Unlike a traditional IRA or 401k, contributions are made with after-tax dollars, meaning you do not get a tax deduction when you contribute. The tradeoff is substantial: your money grows completely tax-free, and qualified withdrawals in retirement are also completely tax-free.
For a young earner who will likely be in a higher tax bracket in retirement than today, this is an extraordinary deal. Every dollar of growth, dividends, and capital gains inside the Roth accumulates without the IRS ever taking a cut.
2026 Contribution Limits and Income Limits
For 2026, you can contribute up to $7,000 per year to a Roth IRA if you are under 50. If you are 50 or older, the limit increases to $8,000.
However, your ability to contribute phases out at higher incomes. The phase-out ranges for 2026 are:
- Single filers: Phase-out begins at $150,000, eliminated at $165,000
- Married filing jointly: Phase-out begins at $236,000, eliminated at $246,000
If your income is above these limits, look into the Backdoor Roth IRA strategy, which legally allows high earners to still fund a Roth through a conversion process.
How to Open a Roth IRA
Opening a Roth IRA takes about 15 minutes online. The three best brokerages for beginners are:
- Fidelity: No minimums, no account fees, and their index funds (like FSKAX) have a 0% expense ratio. Best overall for beginners.
- Vanguard: The pioneer of index fund investing. Slight learning curve on the website but excellent funds.
- Schwab: Clean interface, no minimums, solid fund selection.
You will need your Social Security number, bank account information for the initial transfer, and about 10 minutes. The account is typically ready to use same day.
What to Invest In Once It Is Open
Opening the account is step one. Step two, which many people miss, is actually investing the money. Money sitting in a Roth IRA as cash earns almost nothing. You need to purchase investments.
For most beginners, a single total stock market index fund is the right starting point:
- At Fidelity: FSKAX (0% expense ratio)
- At Vanguard: VTSAX or VTI (0.03% expense ratio)
- At Schwab: SWTSX (0.03% expense ratio)
These funds own a small piece of every publicly traded US company. When the US economy grows, your investment grows with it.

The Power of Starting Early
The math on early Roth IRA contributions is staggering. If you contribute $7,000 per year starting at age 25 and earn a 7% average annual return, by age 65 you will have approximately $1.48 million, completely tax-free. If you wait until 35 to start, that same contribution schedule produces $735,000 - still impressive, but roughly half as much, from waiting just 10 years.
Action Plan
1. Go to fidelity.com and open a Roth IRA (takes 15 minutes). 2. Transfer $500 or more to get started. 3. Buy FSKAX with your balance. 4. Set up a monthly automatic contribution of whatever you can afford. 5. Increase it by $50 per year. Done.
Rules to Know
A few important Roth IRA rules to be aware of. You can withdraw your contributions (not earnings) at any time, for any reason, without taxes or penalties. This makes the Roth IRA a surprisingly flexible account. You cannot withdraw earnings tax-free until age 59.5 and the account has been open for at least 5 years. There are no required minimum distributions during your lifetime, unlike traditional IRAs and 401ks. This makes the Roth excellent for legacy planning as well.
