If there’s one financial account you should open before 35, it’s a Roth IRA. Not a side hustle. Not a robo-advisor app. Not a crypto wallet. A Roth IRA — because it offers something no other account in the US tax code offers: tax-free growth on your investments, forever.
Here’s everything you need to know.
What Is a Roth IRA?
A Roth IRA is an Individual Retirement Account funded with after-tax dollars. You put money in, invest it, it grows — and when you withdraw it in retirement, you pay zero taxes on any of it. Not on the contributions, not on the decades of compound growth.
The “Roth” part refers to Senator William Roth, who sponsored the legislation creating it in 1997. The “IRA” part just means it’s an individual retirement account you open yourself, not through an employer.
How It’s Different From a Traditional IRA and a 401(k)
Traditional IRA: Contributions may be tax-deductible now (reducing your current taxable income), but you pay regular income tax when you withdraw in retirement. You’re deferring taxes, not eliminating them.
401(k) (traditional): Employer-sponsored, contributions are pre-tax, withdrawals taxed in retirement. Same tax structure as traditional IRA, just through your job.
Roth IRA: Contributions are after-tax (no deduction now), but growth and withdrawals are completely tax-free. You pay taxes now; you never pay them again on that money.
Roth 401(k): Some employers offer this — same Roth benefit (after-tax, tax-free growth) but inside a 401(k) structure.
Which is better? It depends on whether you expect to be in a higher or lower tax bracket in retirement. Most young people with moderate incomes today will be in higher tax brackets later (more income, potentially higher rates). Paying taxes now (Roth) is usually better for them. For high earners at peak income now who expect lower income in retirement, traditional often wins.
When in doubt: if you’re under 40 and not yet in a high tax bracket, the Roth IRA almost always wins.
The 2026 Contribution Rules
Annual limit: $7,000 per year ($8,000 if you’re 50 or older — the “catch-up contribution”)
Income limit to contribute the full amount:
- Single filers: modified adjusted gross income (MAGI) below $146,000
- Married filing jointly: MAGI below $230,000
Phase-out range (partial contribution allowed):
- Single: $146,000 – $161,000
- Married: $230,000 – $240,000
Above the phase-out: You can’t contribute directly to a Roth IRA. (High earners have a workaround called the “backdoor Roth IRA” — worth researching if you’re in this situation.)
Important: The $7,000 limit is across all your IRAs combined, not $7,000 per IRA. If you have both a traditional and a Roth IRA, your combined contributions can’t exceed $7,000.
You can contribute to a Roth IRA for the prior tax year until the April 15 filing deadline. Right now in 2026, you can still contribute for 2025 until April 15, 2026.
The Flexibility Most People Don’t Know About
Here’s what makes the Roth IRA genuinely different from other retirement accounts: you can withdraw your contributions (not earnings) at any time, for any reason, with no penalties and no taxes.
You contributed $7,000 last year. That $7,000 in contributions can be pulled out tomorrow — no 10% early withdrawal penalty, no taxes. (Your earnings stay in and are subject to the usual retirement withdrawal rules.)
This makes the Roth IRA something of a hybrid — it’s a retirement account, but the contributions are accessible. It can serve as a long-term emergency fund in addition to a retirement vehicle.
Common legitimate Roth withdrawal scenarios before retirement:
- First home purchase: Up to $10,000 in earnings (not just contributions) can be withdrawn penalty-free for a first home purchase after the account has been open 5 years
- Disability: Withdrawals are penalty-free if you become disabled
- Health insurance premiums while unemployed: Penalty-free
The 5-year rule matters: your account must have been open for at least 5 years before earnings withdrawals are fully tax-free in retirement. Another reason to open it as early as possible even if you only put in $100 to start — the clock starts ticking on the 5-year rule on the date you open the account.
What to Invest in Inside Your Roth IRA
Opening a Roth IRA is just opening an account. The money inside the account needs to be invested in something to grow. A Roth IRA holding cash is just a savings account with extra steps.
For beginners, one fund is enough:
-
Target-date retirement fund — the simplest possible choice. A “2055 fund” or “2060 fund” (pick the year closest to when you’ll turn 65) automatically adjusts its allocation as you age — more stocks now, more bonds as you approach retirement. You contribute; the fund manages itself.
-
S&P 500 index fund — tracks the 500 largest US companies. Historical return of roughly 10% annually (7% after inflation). Low fees, high diversification.
-
Total stock market index fund — similar to S&P 500 but includes smaller companies. Very slightly more diversified.
At Fidelity (recommended for beginners): FZROX (total market, 0% fee) or FNILX (S&P 500, 0% fee) are both excellent and free.
The Math That Makes Young People Regret Waiting
This is the most important section. Read it twice.
Two people open Roth IRAs:
Investor A opens a Roth IRA at 22 and contributes $200/month for 10 years, then stops at 32. Total contributed: $24,000.
Investor B waits until 32 to open their Roth IRA, then contributes $200/month for 30 years until retirement at 62. Total contributed: $72,000.
Assuming 7% annual growth:
- Investor A at 62: approximately $264,000 — from only $24,000 of contributions
- Investor B at 62: approximately $243,000 — from $72,000 of contributions
Investor A contributed one-third as much but ended up with more money because they started 10 years earlier. That’s compound interest — your money makes money, and that money makes more money.
Every year you wait, you give up the most powerful years of compounding. A 22-year-old’s dollar has 43 years to compound before traditional retirement at 65. A 32-year-old’s dollar only has 33. That 10-year head start is worth more than decades of extra contributions.
