What is the best robo-advisor for a Roth IRA?

Fidelity Go is the best robo-advisor for a Roth IRA under $25,000 — it charges $0 in fees and uses zero-expense-ratio funds. For balances above $25,000, M1 Finance (flat $36/year) or Betterment (0.25%) are strong choices depending on whether you want portfolio control or full automation. Tax-loss harvesting has no benefit inside a Roth IRA.

Does tax-loss harvesting matter in a Roth IRA?

No. Tax-loss harvesting has no benefit inside a Roth IRA. Roth IRA withdrawals are tax-free in retirement, so there are no capital gains taxes to offset. When choosing a robo-advisor for your Roth IRA, focus on fees and fund expenses — not tax-loss harvesting.

What is the Roth IRA contribution limit for 2026?

The 2026 Roth IRA contribution limit is $7,000 per year ($8,000 if you are 50 or older). Income limits apply: the ability to contribute phases out at $150,000–$165,000 (single filers) and $236,000–$246,000 (married filing jointly). Above these limits, consider a backdoor Roth conversion.

Can I open a Roth IRA with a robo-advisor?

Yes. All major robo-advisors — Betterment, Wealthfront, M1 Finance, Fidelity Go, and Schwab Intelligent Portfolios — offer Roth IRA accounts. The process takes about 10 minutes and requires your Social Security number and a bank account for funding.

Which robo-advisor has the lowest fee for a Roth IRA?

Fidelity Go charges $0 for Roth IRA balances under $25,000 (including 0% fund expense ratios). M1 Finance Basic charges $0 at all balances (you pay only the ETF expense ratios of your chosen funds). Above $25,000, compare Fidelity Go (0.35%) vs Betterment (0.25%) vs M1 Premium ($36/year flat).

Best Robo-Advisor for Roth IRA 2026 — Top Picks Compared

The best robo-advisor for a Roth IRA in 2026 is Fidelity Go for balances under $25,000 (zero total cost) and M1 Finance or Betterment for larger balances. Inside a Roth IRA, tax-loss harvesting provides no benefit — so the only factors that matter are fees, fund expenses, minimum investment, and the quality of portfolio management. This changes the comparison significantly compared to taxable accounts where Betterment and Wealthfront’s TLH justifies their 0.25% fee.

2026 Roth IRA Contribution Limits

Filing Status	Contribution Limit	Phase-Out Range
Single / Head of Household	$7,000 ($8,000 age 50+)	$150,000 – $165,000 MAGI
Married Filing Jointly	$7,000 ($8,000 age 50+)	$236,000 – $246,000 MAGI
Married Filing Separately	Reduced / $0	$0 – $10,000 MAGI

Above the phase-out range, you cannot contribute directly to a Roth IRA. Consider a backdoor Roth conversion if your income exceeds these limits.

Why Tax-Loss Harvesting Doesn’t Matter in a Roth IRA

Tax-loss harvesting works by realising losses in a taxable account to offset capital gains and reduce your tax bill. Inside a Roth IRA:

All growth is already tax-free
Withdrawals in retirement are tax-free
There are no capital gains taxes to offset

This means Betterment and Wealthfront’s primary fee justification (TLH) disappears entirely inside a Roth IRA. The fee comparison shifts decisively toward low-cost platforms.

3. Betterment — Best for Hands-Off Automation With No Minimum

Why: If you want complete automation (no fund selection, no decisions) and start with less than $500, Betterment’s $0 minimum is a key advantage over M1 Finance. The 0.25% fee is the trade-off for full automation.

$0 minimum — start with any amount
Full automation — no portfolio decisions required
Goal-based retirement planning tools
Automatic rebalancing and deposit management

Note: Inside a Roth IRA, tax-loss harvesting has no benefit. You’re paying 0.25% purely for the automation and goal tools.

4. Wealthfront — Best for $100,000+ Roth IRA With Direct Indexing Plans

Why: If you expect your Roth IRA to grow above $100,000 and you want Wealthfront’s direct indexing once you move the funds to a taxable account, maintaining your portfolio at Wealthfront keeps everything in one place. But for Roth IRA-only investors, direct indexing provides no immediate benefit.

$500 minimum
0.25% fee
529 account support alongside IRA
No human advisor
