Best Robo-Advisors for Retirement: What Changes in an IRA
Last updated August 2026
Short answer
Choosing for a retirement account changes what you should weigh. Tax-loss harvesting is worth nothing in an IRA, so any premium tier priced around it is worth less than it looks. The glide path matters more, because the horizon is long and the date is known. Betterment and Wealthfront lead on goal-based de-risking, Fidelity Go suits a rollover into a custodian you already use, and Vanguard Digital Advisor is the lowest fee actually charged. Almost nothing in the category handles the withdrawal phase well. Walnut is not a robo-advisor and is not an investment adviser.
Most retirement roundups are the general roundup with the word retirement added. That misses the actual difference, which is that two of the headline features robo-advisors compete on stop working entirely inside an IRA, and one that barely gets discussed becomes the most important thing on the page.
What applies in a retirement account, and what does not
| Feature | Worth in an IRA | Why |
|---|---|---|
| Tax-loss harvesting | Worth nothing | No taxable gains exist inside an IRA to offset |
| Direct indexing | Worth nothing | Its entire purpose is tax management in a taxable account |
| Automatic rebalancing | Worth the same or more | Decades of drift, and rebalancing inside an IRA triggers no tax at all |
| The glide path | Worth much more | A retirement date gives the allocation something to aim at |
| Asset location | Worth thinking about | Which account holds which asset matters once you have both types |
| Withdrawal and income | Barely served | Most of the category is built for accumulation, not for drawing down |
The first two rows are the ones that change decisions. If you are choosing a platform for an IRA and comparing premium tiers, check what those tiers contain besides tax features, because in this account the tax features are inert.
The platforms, on what matters here
| Option | Retirement accounts supported | Glide path |
|---|---|---|
| Betterment | Traditional, Roth, SEP and inherited IRAs, plus rollovers and taxable accounts | Goal-based: you set a retirement date and the allocation becomes more conservative as it approaches |
| Wealthfront | Traditional, Roth and SEP IRAs, rollovers, plus 529s and taxable accounts | Automated allocation matched to the risk score, adjusted toward the retirement horizon |
| Fidelity Go | Traditional, Roth and rollover IRAs, plus taxable accounts | Allocation matched to horizon, managed within the firm's own funds |
| Keep your own broker (not a robo-advisor) | Whatever IRA or rollover account you already hold | None. Any de-risking toward retirement is a decision you make and execute yourself |
| Schwab Intelligent Portfolios | Traditional, Roth, SEP, SIMPLE and inherited IRAs, plus rollovers | Allocation matched to horizon and risk, with a required cash position throughout |
| Vanguard Digital Advisor | Traditional, Roth and rollover IRAs, plus taxable accounts | Index-based allocation with a horizon-driven path, at a very low all-in fee |
| SoFi Robo Investing | Traditional, Roth and SEP IRAs, plus rollovers | Horizon-matched allocation inside a broader money app |
How this was ranked
On what applies inside a retirement account: breadth of IRA types, whether the allocation actually de-risks toward a date, cost that is charged rather than waived, and how the platform handles a rollover in. Tax features are deliberately excluded from the ranking, because they do nothing here.
To be upfront, since this is our site: the fourth entry is Walnut's category and is not a robo-advisor. It sits fourth rather than first because a retirement ranking is largely about running a glide path over decades, and keeping your own broker means nobody runs one. On a ranking by cost the same option is first; here it honestly is not.
1. Betterment
Retirement accounts. Traditional, Roth, SEP and inherited IRAs, plus rollovers and taxable accounts
Glide path. Goal-based: you set a retirement date and the allocation becomes more conservative as it approaches
Best for. Accumulating in an IRA with a target date and wanting the de-risking handled automatically
Where it falls short. The tax features that justify the standard fee do most of their work in taxable accounts, not here.
2. Wealthfront
Retirement accounts. Traditional, Roth and SEP IRAs, rollovers, plus 529s and taxable accounts
Glide path. Automated allocation matched to the risk score, adjusted toward the retirement horizon
Best for. People who want strong planning projections alongside the account rather than just the portfolio
Where it falls short. Direct indexing and the deeper tax tooling are taxable-account features, so an IRA-only user pays for less.
3. Fidelity Go
Retirement accounts. Traditional, Roth and rollover IRAs, plus taxable accounts
Glide path. Allocation matched to horizon, managed within the firm's own funds
Best for. Rolling into a custodian you already use, at no advisory fee below the balance threshold
Where it falls short. The fee begins above the threshold, and planning tooling is thinner than the platforms charging more.
4. Keep your own broker (not a robo-advisor)
Retirement accounts. Whatever IRA or rollover account you already hold
Glide path. None. Any de-risking toward retirement is a decision you make and execute yourself
Best for. People already holding a retirement portfolio who want to understand it rather than replace it
Where it falls short. Nothing manages the glide path, nothing rebalances, and nothing converts the portfolio into income later. On a retirement-account ranking, that is a real gap and it is why this sits fourth rather than first.
5. Schwab Intelligent Portfolios
Retirement accounts. Traditional, Roth, SEP, SIMPLE and inherited IRAs, plus rollovers
Glide path. Allocation matched to horizon and risk, with a required cash position throughout
Best for. Broad IRA type coverage at no advisory fee, if the cash requirement is acceptable
Where it falls short. A permanent cash allocation is a heavier cost over a 30-year retirement horizon than over a short one.
6. Vanguard Digital Advisor
Retirement accounts. Traditional, Roth and rollover IRAs, plus taxable accounts
Glide path. Index-based allocation with a horizon-driven path, at a very low all-in fee
Best for. Long-horizon index savers who want the lowest fee that is actually charged rather than waived
Where it falls short. A meaningful account minimum, and fewer planning features than the pricier platforms.
7. SoFi Robo Investing
Retirement accounts. Traditional, Roth and SEP IRAs, plus rollovers
Glide path. Horizon-matched allocation inside a broader money app
Best for. Beginners consolidating a small rollover alongside banking
Where it falls short. Thinner retirement planning tooling, and free-tier terms in this category have changed before.

What a glide path actually looks like over 30 years
The word makes it sound like a smooth continuous adjustment. In practice most platforms move the allocation in steps as the target date approaches, and the shift is concentrated in the last decade rather than spread evenly across the whole horizon. Early on, two platforms with different stated glide paths can be holding almost the same thing.
Two questions separate them, and neither appears in a comparison table. Where does the glide path end? Some platforms de-risk to a conservative allocation at the retirement date and stop; others keep adjusting through retirement, which matters because a portfolio that has to last thirty more years cannot be entirely in bonds. Can you override it? If your circumstances change, being locked to a date you chose in your thirties is worth knowing about in advance.
The gap nobody fills: drawing the money down
Every platform above is built for accumulation. Contribute, allocate, rebalance, repeat. The problem that begins on the day you retire is different: which account to draw from first, how to sequence withdrawals so the tax bill is not lumpy, and how required minimum distributions interact with everything else.
The automation barely touches this, and it is the point at which a human advisor's higher fee starts looking reasonable for many people. See is a robo-advisor cheaper than a financial advisor and tax-efficient retirement strategy.

FAQ
Does a glide path adjust smoothly or in steps?
Usually in steps, and the shift is concentrated in the decade before the target date rather than spread evenly. Early in the horizon, two platforms with different stated glide paths are often holding much the same allocation, so the difference between them matters more later than it does at the start.
Does the glide path stop at retirement?
It varies, and it is worth asking. Some platforms de-risk to a conservative allocation at the target date and hold it; others continue adjusting through retirement. It matters because a portfolio that still has to last thirty years cannot sensibly sit entirely in bonds on the day you stop working.
What is the best robo-advisor for retirement?
It depends on the account and the stage. For accumulating in an IRA with automatic de-risking toward a retirement date, Betterment and Wealthfront lead on goal-based glide paths. Fidelity Go is strong if you are rolling into a custodian you already use. Vanguard Digital Advisor is the lowest fee actually charged. Schwab has the broadest IRA type coverage, with a cash requirement as the cost.
Does tax-loss harvesting matter in a retirement account?
No, and this is the single biggest change to the criteria. Tax-loss harvesting works by realising losses to offset taxable gains, and an IRA or 401(k) has none. If a platform's premium tier is priced around its tax features, that tier is worth materially less to you in a retirement account than the marketing implies.
What is a glide path?
The plan for making a portfolio gradually more conservative as a target date approaches, usually by shifting from stocks toward bonds. In a retirement account it matters more than almost anything else a robo-advisor does, because the horizon is long enough for the shift to be significant and the date is known in advance.
Can I roll my 401(k) into a robo-advisor?
Yes. Almost all of them accept rollovers into a traditional or Roth IRA, and a direct rollover from the plan to the new IRA avoids the withholding and the 60-day rule that a distribution to yourself would trigger. The receiving platform usually handles the paperwork.
Are robo-advisors good for people already retired?
Less so, and this is the category's weakest area. Nearly every platform is built for accumulation: contribute, allocate, rebalance. Drawing an income, sequencing withdrawals across account types, and managing required minimum distributions are barely served by the automation, and are the point at which a human advisor becomes worth the higher fee for many people.
Should I use a robo-advisor or a target-date fund for retirement?
They do a very similar job. A target-date fund is a single fund that glides automatically and typically costs a low expense ratio with no advisory fee on top. A robo-advisor adds account-level features, planning tools and a more granular allocation, for an advisory fee. If your retirement account holds nothing else and you want simplicity, the fund is hard to beat on cost.
Does a robo-advisor handle required minimum distributions?
Coverage varies and it is worth asking directly rather than assuming. Some platforms calculate and can automate the distribution from a traditional IRA once you reach the age at which RMDs begin; others leave it entirely to you. Getting it wrong carries a penalty, so confirm before you need it.
Is it worth moving an existing IRA to a robo-advisor?
The tax friction that makes this question hard in a taxable account does not exist here: moving an IRA to another IRA is not a taxable event, whether positions transfer in kind or are sold. So the decision rests purely on whether you want the allocation managed for you, and what it costs.
