Can I have a Roth IRA at multiple brokers?

Yes, there's no limit on the number of Roth IRAs, only on the combined contribution amount ($7,000 in 2026, $8,000 if 50+). Most people keep one Roth at one broker to simplify recordkeeping.

Is a Roth at a robo-advisor 'worth' the 0.25% fee?

Over 30 years, 0.25% compounds to roughly 7% of your ending balance. If the alternative is not contributing at all, the fee is irrelevant. If you'd otherwise pick a 3-fund portfolio yourself, you'll save money DIY.

Should I roll my old 401(k) into the new Roth?

A traditional 401(k) rolled into a Roth IRA is a taxable conversion, the converted amount is added to that year's taxable income. Only worth it in low-income years or if you have cash outside the account to pay the tax bill.

Best Roth IRA Brokers for 2026

By Yinka Olayokun Published May 12, 2026 Reviewed May 12, 2026

Quick Answer

The best Roth IRA brokers in 2026 charge $0 to open and maintain the account, $0 commissions on stocks and ETFs, and offer total-market index funds with expense ratios under 0.05%. For most savers, the brokerage that already holds your taxable account is the right pick, the marginal feature differences are tiny compared to the cost of not contributing.

How we picked

Account-opening minimum and ongoing fees (should be $0)
Commission-free stock and ETF trading
Availability of in-house total-market index funds under 0.05% ER
Backdoor-Roth conversion workflow quality
Tax-document quality (clean 5498 and 1099-R reporting)

Full-service broker with in-house index funds

Owns the cheapest total-market funds in the industry and bundles them inside a $0-fee Roth wrapper.

• Account minimum: $0
• Stock/ETF commission: $0
• In-house total-market ER: 0.03%
• Backdoor conversion: in-app

Lowest-cost index funds available

Best mobile app in the category
Fractional shares on all ETFs
Same-day customer support

Smaller library of niche funds

Robo-advisor with Roth wrapper

Best for: Investors who want zero decisions

Automated rebalancing and tax-aware allocation inside a Roth, at a 0.25% advisory fee.

• Account minimum: $0–$500
• Advisory fee: 0.25%/year
• Underlying ETF ER: 0.06–0.10%
• Roth conversion: not automated

Pros

No allocation decisions to make
Automatic rebalancing
Goal-based dashboards

Cons

0.25% advisory fee compounds over 30 years
Less flexibility for self-directed picks

How we picked

We compared every major U.S. broker that offers a Roth IRA, scoring them on five factors: cost (account fees + fund ERs), product depth (index, target-date, fractional), tax-document quality, conversion-workflow quality, and customer-service responsiveness.

Cost is the heaviest weight because 30+ years of compounding makes even a 0.10% fee gap into five-figure differences at retirement.

What changed for 2026

Two brokers dropped their default total-market ER to 0.03%, undercutting the previous floor. One major robo-advisor cut its Roth advisory fee from 0.30% to 0.25%, closing the gap with DIY brokers.
