Best Index Funds for a Roth IRA (2026 Guide)Best Index Funds for a Roth IRA

1Why Index Funds and a Roth IRA Work Together

In a Roth IRA you pay tax on the money going in, then qualified withdrawals in retirement are tax free, including all the growth.

That makes a Roth a good home for investments you expect to grow the most over many years, like stock index funds. Because sales inside the account are not taxed, you can also hold Fidelity ZERO funds there without worrying about the transfer catch. Low fees matter even more over 30 years, since every dollar not paid in fees keeps compounding tax free.

2Funds People Commonly Use in a Roth IRA

Broad funds keep it simple. Fees are as of November 2026.

Many Roth investors use a single total market fund, or a US fund plus an international fund. Target date index funds, which shift from stocks to bonds as you age, are another hands off option.

1. VOO or FXAIX: S&P 500, 0.03% and 0.015%
2. VTI, FSKAX or FZROX: total US market, 0.03%, 0.015% or 0%
3. VXUS or FTIHX: international stocks, about 0.05% to 0.06%
4. Target date index funds such as Vanguard Target Retirement: about 0.08%

32026 Roth IRA Rules in Plain English

You can contribute up to $7,500 for 2026, or $8,600 at age 50 and up, if you have earned income and are under the income limit.

Income limits apply, and they rise most years, so check the current IRS numbers before contributing. You can take out your own contributions any time, but taking out earnings early can mean tax and a 10% penalty unless an exception applies. The deadline to contribute for a tax year is usually the April tax filing date of the next year.

4Put It on Autopilot

Set up a monthly transfer and automatic buy so your Roth fills itself.

$7,500 a year works out to $625 a month, but any amount helps. Automating it means your future self gets paid first.
