Robo-Advisor Tax-Loss Harvesting: What “No Extra Fee” Means

Updated September 26, 2026.

“No extra fee for tax-loss harvesting” can mean the feature is included in a paid service, not that the entire arrangement has no cost. Read the service fee, investment expenses, eligibility and implementation terms together.

The feature can be useful, but a harvested loss is not the same as a guaranteed return improvement. Compare the complete arrangement and the investor's circumstances rather than a headline alone.

Separate three price claims

A provider may say there is no additional charge to enable a feature. It may charge no advisory fee while having other disclosed economics. Or it may offer a genuinely free analysis tool that does not implement trades.

Those are different propositions. Ask what you pay for management, underlying investments, transactions and any additional services. The SEC's fee guidance explains why ongoing expenses belong in the evaluation. Investor.gov fee guide

Do not assume that every zero-fee headline is misleading. Identify exactly which charge is zero and which costs remain.

Current managed-service examples

Wealthfront advertises Automated Investing at a 0.25% annual advisory fee, with tax-loss harvesting among its features. That is an included feature within a managed arrangement. Wealthfront pricing

Fidelity Go currently has no advisory fee under $25,000 and charges 0.35% from $25,000. Its higher tier includes harvesting for eligible taxable accounts, alongside other services. Fidelity Go

Schwab Intelligent Portfolios has no advisory fee or commissions, but underlying ETF expenses apply and portfolios include a cash allocation. Eligible accounts of at least $50,000 can enroll in harvesting. Schwab Intelligent Portfolios

These facts do not rank the providers by after-tax outcome. They show why eligibility and the full service arrangement must be read with the feature claim.

A loss amount is not a tax-saving amount

Suppose an illustrative transaction realizes a $2,000 loss. If a simplified scenario assumes that the entire loss offsets gains taxed at 20%, the modeled current tax reduction is $400.

That is not a universal result. Other gains and losses, applicable limitations, later basis and future transactions can change the benefit. The example also excludes costs and the investment effects of a replacement holding.

IRS Publication 550 explains capital-loss treatment and wash sales. Relevant substantially identical purchases in the 30 days before or after a loss sale can affect the treatment, including certain activity in retirement or related accounts. IRS Publication 550

Outside accounts can matter

A managed service may only control the accounts covered by its mandate. Purchases elsewhere can still be relevant to a household review. Confirm what outside information the provider receives and what the customer must disclose or coordinate.

Do not infer complete coordination merely because an outside account can be linked. A connection can provide some information without granting trading authority or supplying every tax record.

Similarly, do not assume a single brokerage's tax document resolves every cross-account issue. Preserve the relevant records and obtain appropriate tax review.

Compare incremental benefit with incremental cost

If you already want the managed service for portfolio implementation, harvesting may be one included benefit among several. If you are considering the service only for harvesting, the entire incremental cost deserves attention.

A single year with a large loss does not establish a permanent annual benefit. A year with few opportunities does not automatically mean the broader managed service has no value.

Keep cash-allocation claims fair

A service's cash policy can affect the portfolio, but its effect is not a fixed annual penalty. It depends on cash yield, the alternative assets and their risks and returns.

Do not combine an assumed cash drag with a promised tax benefit and present the net as a certain result. Each component needs its own assumptions. For a transparent illustration, see Schwab versus DIY cost analysis.

Where Mezzi fits

Mezzi offers advice across supported investments, banking, other assets and liabilities, with AI Personalization for goals and rules and Exposure X-Ray for supported fund exposure. Mezzi account groups

It can help organize questions about the broader financial picture. It does not automatically execute harvesting trades, guarantee wash-sale detection or file a tax return. Verify whether the necessary lot and transaction information is available.

Free includes aggregation and limited AI; Advisory is $399 annually and Concierge $999 annually. Compare the advice service with the work it performs, not as though it includes the same managed execution as a robo-advisor. Mezzi pricing

Compare the incremental service, not the advertised loss total

Suppose a report identifies $8,000 of realized losses. An illustration using a 15% applicable offset rate produces $1,200 of current tax reduction only if the losses can actually offset income taxed at that assumed rate. Usability, wash-sale treatment, other gains and losses, and future consequences affect the result. A reported loss is not a cash rebate. IRS Publication 550

If the household would have realized some losses through its existing process, only the difference attributable to the new service belongs in an incremental comparison. Likewise, include fees that change because of the service, not costs already present in both arrangements.

Ask the provider to distinguish losses harvested, estimated current tax effects and assumptions about future realization. Do not subtract a projected lifetime benefit from this year's subscription as if both were certain cash flows.

Mezzi's analysis can help organize tax-sensitive questions, but it does not execute harvesting trades. A managed platform that implements eligible harvesting under its agreement supplies a different responsibility. Compare the actual work and constraints alongside the marketing claim about price.

Make the decision on the complete service

Ask for the current terms and define what would make the arrangement useful for you. Keep the fee estimate, eligibility, tax assumptions and implementation responsibilities together.

The right question is not whether the feature sounds free. It is whether the complete service fits the household and whether the expected benefit has been described honestly.

Frequently asked questions

Does no extra harvesting fee mean no total cost?

Not necessarily. It may mean the feature is included in a service with advisory, investment or other costs.

Is a harvested loss the same as tax savings?

No. The tax effect depends on the applicable treatment and the investor’s other facts, and future consequences can matter.

Can purchases outside the managed account matter?

Yes. Relevant outside or related-account activity can affect the analysis. Confirm the provider’s scope and your coordination responsibilities.

Does Mezzi automatically harvest losses?

No. Mezzi supports advice and analysis, while you implement transactions through your institutions.
