Tax-loss harvesting is the one feature that can make a robo-advisor’s fee irrelevant — or completely pointless, depending on where your money sits. Sell an investment at a loss, use that loss to offset capital gains elsewhere, and in a good year the tax savings can outweigh what you’re paying in management fees several times over. In a flat or steadily rising market, the same feature can sit dormant and do almost nothing.
This is the highest-CPC keyword in the entire robo-advisor space, and yet most comparisons cover it in a single paragraph. Here’s the detailed version: which platform actually harvests better, what direct indexing changes at scale, and — just as important — when tax-loss harvesting isn’t worth paying extra for at all.

Quick Verdict
- Best overall for tax-loss harvesting: Wealthfront. Daily ETF-level harvesting, plus stock-level direct indexing once your account crosses $100,000 — the most powerful tax-optimization stack among mainstream robo-advisors.
- Best if you also want portfolio flexibility or human advisor access: Betterment. Matches Wealthfront on standard ETF-level harvesting and adds tax-coordinated asset location across linked accounts.
- Skip this feature entirely if: your money is in a Roth or Traditional IRA. Tax-loss harvesting only applies to taxable brokerage accounts — in an IRA, it does nothing.
What Tax-Loss Harvesting Actually Does
When an investment in your taxable account drops below what you paid for it, tax-loss harvesting sells it and immediately buys a similar (but not identical) replacement — keeping your overall market exposure intact while “locking in” the loss for tax purposes. That realized loss can then offset capital gains elsewhere in your portfolio, and if losses exceed gains in a given year, up to $3,000 can offset ordinary income, with the remainder carried forward to future years.
The IRS wash-sale rule prevents you from buying back the identical security within 30 days and still claiming the loss — which is exactly why robo-advisors swap into a similar-but-not-identical fund rather than simply repurchasing the same one.
This only works in a taxable brokerage account. In a Roth or Traditional IRA, gains and losses aren’t taxed annually in the first place, so there’s nothing to harvest against — the feature provides zero benefit there, no matter how sophisticated the platform’s algorithm is.
Side-by-Side: How the Major Platforms Compare
| Platform | TLH method | Minimum for TLH | Fee | Notable detail |
|---|---|---|---|---|
| Wealthfront | Daily, ETF-level | Any taxable balance | 0.25% | Direct indexing (stock-level TLH) at $100,000+ |
| Betterment | Automatic, ETF-level | Any taxable balance | 0.25% (Basic) | Tax-coordinated portfolio across linked accounts |
| Schwab Intelligent Portfolios | ETF-level | $50,000 | $0 advisory fee | Not available below $50,000 at any tier |
| Fidelity Go | Not offered | N/A | $0 under $25,000 | No TLH at any balance |
| Vanguard Digital Advisor | Not offered | N/A | ~0.15% | No TLH at Digital or Personal Advisor tier |
| M1 Finance | Not offered | N/A | $0 | Self-directed, not an automated TLH feature |
Wealthfront: The Deepest Tax-Optimization Stack
Wealthfront harvests losses daily at the ETF level across every taxable account, regardless of balance. Where it separates from the pack is direct indexing: once a taxable account reaches $100,000, Wealthfront replaces a broad market ETF (like a total U.S. stock market fund) with hundreds of individual stocks that track the same index. Instead of one fund generating one harvesting opportunity, each of those individual positions can be harvested independently — even in years when the overall market is up. Wealthfront has reported that direct indexing can add meaningfully to after-tax returns compared with standard ETF-level harvesting alone, though the exact benefit varies by market conditions and individual tax situation.
The tradeoff: below $100,000, you get the same ETF-level harvesting Betterment offers, so the “deeper” tax stack isn’t accessible until your taxable balance clears that threshold. Wealthfront also doesn’t offer any human advisor access, at any tier — if you want the option to talk to a person, that’s a real gap.
Betterment: Comparable Harvesting, Plus Tax-Coordinated Placement
Betterment’s standard tax-loss harvesting works similarly to Wealthfront’s — automatic, ETF-level, running on taxable accounts since 2014, one of the longer track records in the category. Where Betterment differs is tax-coordinated portfolio placement: if you link multiple account types (taxable, IRA, 401(k)) to Betterment, the platform automatically places tax-inefficient assets like bonds and REITs into tax-advantaged accounts, while keeping tax-efficient assets like stock index funds in the taxable account. This is a form of tax optimization that works across your whole financial picture, not just within a single account.
Betterment doesn’t offer a direct-indexing equivalent to Wealthfront’s at this time, so for very large taxable accounts specifically chasing maximum harvesting depth, Wealthfront currently has the edge. For investors who want the option of a human advisor on a Premium tier, or who value asset location across multiple linked accounts, Betterment’s overall package may matter more than the harvesting depth alone.
Schwab and Fidelity: Why They’re Off This List for Smaller Accounts
Schwab Intelligent Portfolios does offer tax-loss harvesting — but only above $50,000. Below that threshold, taxable accounts get the standard $0-fee service with no harvesting at all, meaning the “free” fee structure and the tax feature don’t overlap until a fairly high balance. Fidelity Go doesn’t offer tax-loss harvesting at any tier, and neither does Vanguard Digital Advisor. If tax-loss harvesting is the specific feature you’re shopping for, these platforms — despite being excellent on other dimensions — aren’t the right fit until (or unless) your balance changes the equation.
When Tax-Loss Harvesting Isn’t Worth Paying For
This is the part most comparisons skip. Tax-loss harvesting is not a guaranteed annual benefit — it’s opportunistic, and its value depends heavily on circumstances:
- In an IRA: zero benefit, regardless of platform. Choose based on fees and features instead.
- In a flat or steadily rising market: fewer harvesting opportunities exist, since there are fewer positions sitting at a loss to sell. The feature can go quiet for extended stretches.
- On a small taxable balance: the dollar value of harvested losses is proportionally smaller, so the tax savings may not clearly exceed the 0.25% fee versus a $0-fee alternative like Fidelity Go.
- If you don’t have other capital gains to offset: harvested losses are most valuable when they offset gains elsewhere (from selling other investments, real estate, or a business). Without gains to offset, the benefit is capped at $3,000 against ordinary income per year, with the rest carried forward.
For a taxable account you expect to hold through real market volatility over many years, the odds of accumulating meaningful harvestable losses go up. For a small, recently opened taxable account in a calm market — or for any IRA — the fee difference between a 0.25% platform and a $0-fee one may matter more than the harvesting feature itself.
Decision Framework
- Large taxable account, want the deepest tax optimization, comfortable without human advisor access → Wealthfront
- Taxable account, want comparable harvesting plus multi-account tax coordination, may want a human advisor later → Betterment
- Taxable account, but balance is well under $50,000 and you don’t want to pay 0.25% for a feature you may not use much yet → Fidelity Go or Vanguard Digital Advisor, revisit later
- Roth or Traditional IRA → skip this feature entirely; choose based on fees, minimums, and portfolio construction instead — see our [best robo-advisor for Roth IRA] guide
Our Methodology
This comparison is based on publicly available fee schedules, feature disclosures, and account-minimum information published by each provider as of 2026. Tax-loss harvesting benefit estimates cited from providers are illustrative figures reported by those companies and vary by market conditions, account size, and individual tax circumstances — they are not a guarantee of results for any specific investor. We do not maintain active accounts with every platform for this specific comparison; treat this article as a starting point for your own research, and consult a tax professional regarding your specific situation before making decisions based on tax-loss harvesting.
Frequently Asked Questions
Does tax-loss harvesting work in a Roth IRA? No. Tax-loss harvesting only applies to taxable brokerage accounts, since IRA gains and losses aren’t taxed annually in the first place.
Is Wealthfront’s tax-loss harvesting really better than Betterment’s? Below $100,000, the two are broadly comparable — both harvest automatically at the ETF level. Above $100,000, Wealthfront’s direct indexing gives it a meaningfully deeper tax-optimization capability that Betterment doesn’t currently match.
Can tax-loss harvesting actually lose me money? The feature itself doesn’t directly cause losses — it responds to losses that already occurred in the market. The wash-sale rule and the use of “similar but not identical” replacement funds mean there can be minor tracking differences versus your original holding, which is a small tradeoff for the tax benefit.
How much can tax-loss harvesting actually save me? It varies significantly by market conditions, account size, and your broader tax situation. Providers publish illustrative estimates, but there’s no fixed annual dollar amount you can count on — treat any figure you see as a historical average, not a guarantee.
