A Fidelity Roth IRA has no account minimum, no annual fee, and gives you access to ZERO expense ratio index funds — the lowest-cost investment option available anywhere. The 2026 contribution limit is $7,000 per year ($8,000 for those 50 and older), and all qualified withdrawals in retirement are completely tax-free. Fidelity’s combination of 0.00% expense ratios and tax-free Roth growth makes it the mathematically optimal choice for long-term retirement saving.

2026 Roth IRA Contribution Limits

Filing status Full contribution Phase-out range Cannot contribute directly
Single / Head of Household Under $150,000 MAGI $150,000–$165,000 Above $165,000
Married Filing Jointly Under $236,000 MAGI $236,000–$246,000 Above $246,000
Married Filing Separately Under $10,000 MAGI $0–$10,000 Above $10,000
Age Annual Roth IRA limit
Under 50 $7,000
50 or older $8,000 (includes $1,000 catch-up)

These limits apply to all your IRAs combined. The contribution deadline for the 2026 tax year is April 15, 2027. You can contribute to both the 2025 and 2026 years if you have not yet maxed out 2025 before the deadline.

Why Fidelity Is the Best Roth IRA for Most Investors

Roth IRA accounts are uniquely well-suited to the ZERO fund strategy. Here’s why:

The ZERO + Roth combination: Fidelity’s ZERO index funds charge 0.00% in annual expense ratios. Inside a Roth IRA, all growth is tax-free. The combination of zero fund costs and tax-free growth means you keep every cent of your returns — no expense drag, no withdrawal taxes, no RMDs.

Fractional shares from $1: You can invest any dollar amount in any stock or ETF at Fidelity, right inside your Roth IRA. If your monthly contribution is $583.33 (the result of spreading $7,000 over 12 months), you can invest the exact amount — not a rounded-down whole share amount.

Fidelity Go inside a Roth: Fidelity’s robo-advisor is free for Roth IRA balances under $25,000, making it one of the only free automated Roth IRA management options available. See the Fidelity Go guide for details.

The Best Fidelity Funds for a Roth IRA

Because Roth IRA growth is permanently tax-free, put your highest-expected-return investments here. The goal is to maximize the assets that benefit most from tax-free compounding.

Fund Type Expense ratio Why it works in a Roth
FZROX US Total Market Index (ZERO) 0.00% Maximum growth, zero cost
FZILX International Index (ZERO) 0.00% International diversification, zero cost
FZIPX Extended Market Index (ZERO) 0.00% Small/mid-cap for higher growth
VNQ / FREL REIT ETF/Fund 0.12–0.13% High dividends compound tax-free
QQQ / VUG Growth ETF 0.20% / 0.07% High growth potential — best in Roth

ZERO fund caveat: FZROX and FZILX cannot be transferred in-kind to another brokerage. If you ever move your account, you must sell them first. In a Roth IRA (where there’s no tax on gains), selling and repurchasing at the new brokerage is a non-event — so this limitation is minimal inside a Roth.

Least effective in a Roth: Municipal bonds (already tax-exempt — wasting the Roth advantage), CDs, or money market funds (low growth means small tax benefit).

Worked Example: ZERO Fund Roth IRA

Sarah, age 25, contributes $7,000/year to a Fidelity Roth IRA, invested in FZROX (0.00% expense ratio). Assuming 7% average annual return:

Year Annual expense (traditional 0.50% ER fund) Annual expense (FZROX, 0.00% ER)
Year 1 $35 $0
Year 10 $510 $0
Year 30 $2,980 $0

Over 40 years, the savings from 0.00% vs. a typical 0.50% expense ratio is estimated at $85,000–$100,000 in additional wealth at retirement — all inside the tax-free Roth wrapper.

The 5-Year Rule

Roth IRA earnings (not contributions) require two conditions before they can be withdrawn tax-free:

  1. You must be 59½ or older
  2. Your Roth IRA must have been open for at least 5 tax years

The 5-year clock starts January 1 of the first year you contributed. A Roth IRA opened in November 2026 has a clock that started January 1, 2026 — it completes January 1, 2031.

Your original contributions can always be withdrawn at any time, at any age, with no tax or penalty.

Backdoor Roth IRA at Fidelity

High earners above the direct contribution income limit can use the backdoor Roth strategy at Fidelity:

  1. Open a Fidelity Traditional IRA (no income limit applies to contributions)
  2. Make a non-deductible contribution — up to $7,000 (or $8,000 if 50+)
  3. Wait for the contribution to settle (1–2 business days)
  4. Convert to Roth IRA — log in to fidelity.com → Accounts → select the Traditional IRA → “Convert to Roth IRA”
  5. File IRS Form 8606 with your tax return — this reports the non-deductible basis and ensures you don’t pay tax twice

Tax owed on conversion: only on any earnings between contribution and conversion date. If you convert within days, the taxable amount is typically a few dollars.

Pro-rata rule: If you have other pre-tax Traditional IRA funds at Fidelity or elsewhere, the IRS calculates your taxable conversion amount proportionally. This can make the backdoor Roth tax-inefficient if you have large pre-tax IRA balances. A tax professional can help you navigate this.

How to Open a Fidelity Roth IRA

  1. Go to fidelity.com → “Open an Account” → “Roth IRA”
  2. Complete the online application (Social Security number, address, beneficiary)
  3. Link a bank account or existing Fidelity account
  4. Fund the account — up to $7,000 for 2026 (deadline: April 15, 2027)
  5. Buy investments — FZROX and FZILX are one-click away in the fund screener
