Betterment vs. Fidelity Go: Best Taxable Account in 2026

Betterment vs. Fidelity Go for Taxable Accounts in 2026: Fees, Tax-Loss Harvesting, and Portfolio Control

Choosing between Betterment and Fidelity Go for a taxable account involves more than comparing two advisory rates. Tax-loss harvesting, underlying fund expenses, portfolio flexibility, access to financial professionals, and investments held in outside accounts can all affect which service is the better fit.

Betterment generally provides more portfolio choices and broader automated tax management. Fidelity Go stands out for charging no advisory fee on balances below $25,000 and for integrating with Fidelity’s broader brokerage, retirement, and cash-management ecosystem.

Important: Pricing, eligibility thresholds, and account features can change. Confirm current fees, portfolio options, tax-management rules, and support benefits on each provider’s website before opening or funding an account.

Quick Verdict: Which Robo-Advisor Fits Your Taxable Account?

Betterment may be the stronger fit if automated tax-loss harvesting is a priority or you want a wider selection of ETF-based portfolio strategies. Betterment can be particularly useful for taxable investors who regularly contribute, expect to realize capital gains, or want tax management without first reaching Fidelity Go’s $25,000 threshold.

Fidelity Go may be the stronger fit if you already use Fidelity, prefer a simple managed portfolio, or expect to maintain a balance below $25,000. Fidelity Go charges no advisory fee below that level. However, tax-loss harvesting and financial coaching generally become available only after the account reaches $25,000.

Tax-loss harvesting applies only to taxable investment accounts. It does not provide the same benefit inside IRAs, Roth IRAs, 401(k)s, or other tax-advantaged retirement accounts because trades within those accounts do not generate currently taxable capital gains or deductible capital losses.

Betterment vs. Fidelity Go: Key Differences at a Glance

Betterment primarily builds portfolios from ETFs issued by multiple fund companies. That structure supports a broader menu of portfolio strategies, but investors also bear the expense ratios charged by the selected ETFs.

Fidelity Go uses proprietary Fidelity Flex mutual funds. These funds have zero expense ratios, simplifying the underlying fund cost, although the available portfolio choices are more limited.

Fees and Minimums in 2026

Betterment Digital fees

Betterment Digital charges $5 per month when an eligible investment balance is below $24,000 and the customer does not make at least $200 in qualifying recurring deposits each month. The monthly charge totals $60 per year.

Accounts with at least $24,000, as well as qualifying smaller accounts with at least $200 in monthly recurring deposits, are generally charged 0.25% annually instead. This distinction is important for smaller balances. On a $10,000 account, $60 per year represents an effective advisory cost of 0.60%. If the same account qualifies for percentage-based pricing, the annual advisory fee would be approximately $25.

Betterment Premium fees

Betterment Premium requires at least $100,000 in eligible investment balances. The annual fee is 0.65% on the first $1 million in eligible balances. That total consists of Betterment’s 0.25% Digital base fee plus an additional 0.40% Premium fee for access to financial professionals and expanded planning support.

The 0.40% figure should not be treated as Premium’s complete advisory charge. At a $100,000 balance, the total 0.65% fee produces an estimated annual advisory cost of $650.

Fidelity Go fees

According to Fidelity’s published Fidelity Go pricing, accounts below $25,000 pay no advisory fee. Once an account reaches $25,000, Fidelity charges 0.35% per year on the account balance—not only on the portion above $25,000.

This creates a significant pricing step. An account just below $25,000 may have no advisory fee, while an account with exactly $25,000 would incur an estimated annual charge of $87.50. Reaching that threshold also unlocks financial coaching and tax-loss harvesting for eligible taxable accounts.

Estimated annual advisory costs

These examples estimate advisory fees only. Betterment investors also pay the expense ratios of the ETFs held in their portfolios. The exact cost varies by portfolio and is deducted within each fund rather than billed as a separate advisory charge.

Fidelity Go’s Flex funds have zero expense ratios. Fidelity also states that the service does not impose separate trading, transaction, or rebalancing fees. Investors should nevertheless review each provider’s disclosures for transfer policies, uncommon account charges, and expenses associated with investments outside the managed portfolio.

Tax-Loss Harvesting for Taxable Investors

Tax-loss harvesting involves selling an investment for less than its tax basis and using the realized loss to offset realized capital gains. Under federal tax rules, excess net capital losses may also offset a limited amount of ordinary income, with unused losses potentially carried into future tax years.

Betterment’s Tax Loss Harvesting+ is an automated strategy designed to monitor eligible taxable holdings for harvesting opportunities. When the system identifies a suitable loss, it may sell the losing position and purchase a replacement investment intended to preserve similar market exposure.

Fidelity Go offers tax-loss harvesting for taxable accounts once the account balance reaches $25,000. Fidelity looks for harvesting opportunities in eligible Fidelity Flex funds that hold stocks. Accounts below $25,000 do not receive this feature.

Wash-sale risk requires a broader review

The wash-sale rule can defer a loss if an investor purchases the same or a substantially identical security within 30 days before or after the loss-producing sale. A robo-advisor may monitor activity inside the account it manages, but it may not have a complete view of transactions in outside accounts.

Potential conflicts can arise through a spouse’s account, an IRA, a workplace retirement plan, another brokerage account, or an automatic dividend-reinvestment program. For example, if a robo-advisor sells a fund at a loss while the investor automatically purchases the same fund elsewhere, the transaction could create a wash sale.

Investors should therefore compare the robo-advisor’s holdings with funds owned across their household. Turning off dividend reinvestment in an overlapping security may sometimes reduce accidental purchases during a wash-sale window, although individual tax circumstances should be reviewed with a qualified professional.

Tax-loss harvesting is tax deferral, not guaranteed savings

Harvesting a loss generally lowers the tax basis of the replacement investment. If that replacement is later sold for a gain, the investor may face a larger future tax bill. The strategy can still be useful when losses offset short-term gains, when the investor expects to be in a lower future tax bracket, or when taxes can be deferred for many years.

A replacement fund can also perform differently from the original investment. Neither provider guarantees that harvesting opportunities will arise or that the strategy will reduce an investor’s lifetime taxes. Results depend on market movements, deposits, withdrawals, holding periods, other transactions, and federal and state tax rules.

Portfolio Control, Investments, and Customization

Betterment offers the broader investment menu. Its portfolios generally use diversified ETFs, and investors can select from multiple strategies, including socially responsible choices and portfolios with different income, factor, or risk characteristics. The available allocation controls depend on the chosen strategy.

Betterment also offers Crypto ETF portfolios. These portfolios are generally subject to Betterment’s standard management fees under the Digital or Premium plan rather than a separate management-pricing model. The underlying crypto-related ETFs may still have their own fund expenses, and the portfolios can experience substantial volatility and other cryptocurrency-specific risks.

Fidelity Go emphasizes simplicity. It recommends an allocation using the investor’s stated goal, time horizon, and risk tolerance, then implements that allocation with Fidelity Flex mutual funds. Fidelity monitors and rebalances the portfolio and may accept reasonable investment restrictions, but it generally offers fewer specialty strategies and customization choices than Betterment.

Both services are built for hands-off management. That convenience limits investor control. Someone who wants to select exact ETFs, own individual stocks, control the timing of every trade, or choose which tax lots to sell may prefer a self-directed brokerage account.

Human Advice, Usability, and Fidelity Ecosystem Benefits

Betterment Premium combines automated portfolio management with access to financial professionals. The service may appeal to investors seeking help with retirement planning, stock compensation, multiple financial goals, or major financial decisions. Customers should review the service agreement to understand the scope of the advice and whether support comes from a dedicated professional or a team.

Fidelity Go customers with at least $25,000 generally receive unlimited 30-minute coaching calls. These sessions can address budgeting, debt, retirement preparation, and goal planning. Coaching can be useful, but it should not automatically be treated as comprehensive tax planning or an ongoing relationship with a dedicated financial planner.

Both providers offer web and mobile access, automatic deposits, goal tracking, portfolio monitoring, and planning tools. Betterment’s experience is organized heavily around financial goals and automated recommendations.

Fidelity’s main usability advantage is account integration. Existing customers may be able to view Fidelity Go alongside self-directed brokerage accounts, IRAs, workplace retirement plans, cash-management accounts, and other Fidelity relationships. That consolidated view can make it easier to monitor household assets, although it does not eliminate the need to check for overlapping investments held elsewhere.

Automated recommendations are only as reliable as the information supplied. Investors should update their income, liquidity needs, risk tolerance, target dates, and financial goals after a job change, major purchase, inheritance, marriage, or other material event.

Pros, Cons, and Alternatives

Betterment pros

• Automated tax-loss harvesting for eligible taxable accounts without Fidelity Go’s $25,000 feature threshold.
• Broader selection of ETF-based portfolio strategies.
• Socially responsible choices and other portfolio variations.
• Goal-based tools and optional access to financial professionals.

Betterment cons

• The $5 monthly fee can represent a relatively high percentage of a small balance.
• ETF expense ratios are paid in addition to the advisory fee.
• Premium requires a $100,000 eligible investment balance and costs 0.65% annually on the first $1 million.
• Crypto ETF portfolios carry substantial volatility and underlying fund expenses.

Fidelity Go pros

• No advisory fee on balances below $25,000.
• Fidelity Flex funds have zero expense ratios.
• Strong integration for investors with other Fidelity accounts.
• Tax-loss harvesting and unlimited financial coaching become available at $25,000.

Fidelity Go cons

• The 0.35% fee applies to the account balance once it reaches $25,000.
• Tax-loss harvesting and financial coaching are unavailable below that threshold.
• Portfolio customization is limited.
• The standard service generally lacks specialty and socially responsible portfolio strategies.

Alternatives worth considering

Schwab Intelligent Portfolios does not advertise a conventional advisory fee for its basic automated service, but portfolios include a cash allocation. That cash can create an opportunity cost and is part of the program’s business model.

Vanguard Digital Advisor may appeal to long-term, index-focused investors seeking automated management. Compare its current minimum, net advisory fee, fund lineup, and taxable-account capabilities before deciding.

A self-directed Fidelity brokerage account offers more control without a robo-advisory fee. It may work for an investor who is comfortable selecting diversified funds, rebalancing periodically, maintaining tax records, and managing tax-loss harvesting manually. The trade-off is the time and tax awareness required.

Who Is Each Service Best For?

Consider Betterment if taxable-account automation is central to the decision, you want tax-loss harvesting below $25,000, or you value multiple portfolio strategies more than consolidating every account at Fidelity.

Consider Fidelity Go if the account will remain below $25,000, you prefer funds with zero expense ratios, or Fidelity account integration matters more than expanded portfolio customization.

At balances of $25,000 or more, compare the complete cost against the features you expect to use. Betterment Digital’s 0.25% advisory rate is lower than Fidelity Go’s 0.35%, although Betterment portfolios also incur ETF expense ratios. Fidelity Go uses zero-expense-ratio Flex funds and includes financial coaching at this balance level.

At $100,000, Betterment customers face another choice: remain with Digital at approximately $250 per year or select Premium at approximately $650 per year. Premium is most relevant when access to financial professionals is valuable enough to justify the additional 0.40% charge.

The value of tax-loss harvesting should not be assumed. An investor with few taxable gains, a low current tax rate, substantial wash-sale exposure, or a short investment horizon may receive less benefit than someone with recurring capital gains and many years to defer future taxes.

What to Do Next Before Choosing

1. Estimate the full annual cost. Apply the correct advisory pricing to the planned balance, then add estimated ETF expense ratios or other portfolio-level expenses.
2. Check Betterment’s pricing conditions. For a balance below $24,000, determine whether at least $200 in qualifying monthly recurring deposits will make the account eligible for 0.25% annual pricing instead of the $5 monthly fee.
3. Check Fidelity Go’s $25,000 threshold. Determine whether the account will qualify for tax-loss harvesting and coaching, and consider whether normal market movements could take the balance below the eligibility level.
4. Review current holdings. Identify unrealized gains, losses, concentrated positions, and funds that could overlap with a robo-advisor’s holdings or replacement securities.
5. Assess household wash-sale exposure. Include taxable accounts, IRAs, spousal accounts, workplace plans, and automatic dividend reinvestments.
6. Decide which benefit matters most. Compare Betterment’s broader automated tax management and portfolio flexibility with Fidelity’s ecosystem integration and no advisory fee below $25,000.
7. Verify current terms. Review each provider’s official pricing page, program disclosure, portfolio methodology, tax-loss harvesting rules, fund expenses, and human-support eligibility before transferring money.

Bottom line: Betterment generally offers the more flexible taxable-account package, especially for investors who want automated tax-loss harvesting before reaching $25,000. Fidelity Go is compelling for smaller accounts and existing Fidelity customers, but its fee and available features change materially when the balance reaches $25,000.
