Trailing commissions are ongoing payments that a mutual fund or annuity company sends to your financial advisor every year you stay invested in the product. The money is pulled directly from the fund’s assets before your return is calculated, so nothing shows up as a withdrawal on your statement. For mutual funds, the rate typically runs between 0.25% and 1.00% of your account balance per year.1Investor.gov. 12b-1 Fees Over a long holding period that quiet drag can cost tens of thousands of dollars, and in most cases you have to go looking to find out what you’re paying.
How the Payment Actually Works
When you buy a mutual fund or annuity through an advisor, the investment company often pays that advisor an upfront commission at the time of the sale. The trailing commission is what comes after: a smaller, recurring annual payment for as long as you hold the product. The fund company deducts it from the fund’s assets, which means it reduces the return earned by every shareholder before any money reaches your account. Your advisor doesn’t bill you, and no line item appears on your statement. The fund simply reports a return slightly below its gross performance.
The arrangement gives your advisor an ongoing reason to keep you invested in the product and available for questions and reviews. It also creates a conflict: the advisor earns more from products that pay higher trails, which may or may not be the products that fit your situation best. That tension drives nearly every disclosure rule covering these payments.
Which Products Pay Trailing Commissions
Mutual Funds and 12b-1 Fees
Mutual funds pay trailing commissions through what the industry calls 12b-1 fees, named for Rule 12b-1 under the Investment Company Act of 1940. The rule lets a fund use shareholder assets to cover distribution and marketing costs, including payments to the brokers who sold the fund.2eCFR. 17 CFR 270.12b-1 – Distribution of Shares by Registered Open-End Management Investment Company
FINRA caps the distribution portion at 0.75% of average annual net assets and the service portion at 0.25%, for a combined annual maximum of 1.00%.3Financial Industry Regulatory Authority (FINRA). FINRA Rule 2341 – Investment Company Securities Plenty of funds charge less than the cap, but the gap between a 0.25% fund and a 1.00% fund grows into real money once compounding runs for a few decades.
Annuities
Variable annuities and fixed indexed annuities also pay trailing commissions, with more variation in structure. Annual trails on variable annuities can run from zero to over 1.00% of the contract value depending on the share class, and some products only begin paying trails after the surrender period ends. Fixed indexed annuities often give the advisor a choice between a higher upfront commission with no trail or a lower upfront with an ongoing annual trail of roughly 0.25% to 1.00%. Payments continue until you surrender or annuitize.
Annuity trails are harder to spot than mutual fund fees because they sit inside the contract’s internal expense structure. The prospectus for a variable annuity, or the disclosure statement for a fixed indexed product, is the only reliable place to see the exact numbers.
Share Classes Decide What You Pay
The share class you buy determines how much of your return goes to trailing commissions. Fund companies offer the same underlying portfolio in several wrappers with different fee structures. The two most common for retail investors are Class A and Class C.
- Class A shares charge a front-end sales load when you buy, often between 3% and 5.75%, then carry a low annual 12b-1 fee of roughly 0.25%.
- Class C shares skip the front-end load but charge a higher ongoing 12b-1 fee, commonly 1.00% per year, for as long as you hold the shares.1Investor.gov. 12b-1 Fees
Over a short holding period, Class C can be cheaper because you avoid the upfront load. Hold for more than a few years and the higher annual trail outruns what the Class A load would have cost. FINRA has flagged exactly this scenario, noting that Class C shares “generally continue to charge higher annual expenses for as long as the customer holds the shares” and that firms should evaluate whether a long-term hold in that class makes sense.4Financial Industry Regulatory Authority (FINRA). Regulatory Notice 12-25 – Additional Guidance on FINRAs New Suitability Rule
Some fund families convert Class C shares into Class A shares automatically after a set holding period, dropping the 12b-1 fee from 1.00% to around 0.25%. There is no universal timeline. Check your fund’s prospectus for the trigger date, or whether a conversion feature exists at all. If it doesn’t, you can be stuck paying the higher trail indefinitely.
What Trailing Commissions Cost Over Time
Trailing commissions are a percentage of your balance, so the dollar amount grows as your account grows. On a $100,000 account, a 0.50% trail costs $500 in the first year. That sounds minor. But every dollar removed from the fund is a dollar that stops earning returns, and the gap compounds.
Take $100,000 invested at a 7% gross annual return over 30 years. With no trailing fee, it grows to roughly $761,000. Add a 1% annual trail and the effective return drops to 6%, leaving about $574,000. The trailing commission consumed roughly $187,000 of potential growth. Even a 0.25% fee, often described as negligible, reduces the same account by about $45,000 over 30 years.
None of this appears as a withdrawal. The fund simply reports a lower return than its gross performance, which is why trailing commissions can run unnoticed for an entire investing lifetime.
How to Find Out What You’re Paying
The most direct check is the fee table in your fund’s prospectus. Look under “Annual Fund Operating Expenses” for the line labeled “Distribution and/or Service (12b-1) Fees.”5U.S. Securities and Exchange Commission. Mutual Fund Fees and Expenses Anything above zero means a portion is almost certainly flowing to your advisor as a trailing commission. The same table includes a hypothetical cost example showing what you would pay on a $10,000 investment over one, three, five, and ten years.
For annuities, the equivalent information lives in the contract’s prospectus or disclosure statement under the expense summary.
What Your Advisor Has to Tell You
Federal rules don’t ban trailing commissions. They require that you be told about them, in several places.
Since June 2020, broker-dealers recommending securities to retail investors have to comply with Regulation Best Interest. The rule requires brokers to disclose, in writing, all material fees and costs you will pay, along with all material conflicts of interest connected to the recommendation.6eCFR. 17 CFR 240.15l-1 – Regulation Best Interest A trailing commission is both. The SEC has said that saying a firm “may” have a conflict when it actually has one is not enough.7U.S. Securities and Exchange Commission. Staff Bulletin – Standards of Conduct for Broker-Dealers and Investment Advisers Conflicts of Interest Reg BI also requires firms to identify and mitigate conflicts at the individual advisor level, meaning disclosure alone does not satisfy the obligation to act in your best interest.
Both broker-dealers and registered investment advisers must also give you Form CRS, a two-page relationship summary that describes the principal fees you will pay, how the firm’s financial professionals are compensated (including third-party payments and revenue sharing), and the conflicts those arrangements create. Mutual fund and variable annuity fees are specifically listed as examples that must be disclosed.8U.S. Securities and Exchange Commission. Form CRS Relationship Summary Form CRS is a starting point, not a full fee schedule, so you’ll still need the prospectus and your advisory agreement for exact numbers.
If you work with a registered investment adviser rather than a broker, you should also receive Part 2A of Form ADV, called the brochure, which describes the adviser’s compensation and any indirect payments from fund companies. If your advisor is dually registered as both a broker-dealer and an investment adviser, both sets of disclosures apply.
Retirement Accounts
When trailing commissions come out of retirement plan assets, ERISA adds another layer. A service provider to the plan can receive no more than reasonable compensation, and all indirect compensation, including 12b-1 fees and similar trails, must be disclosed in writing to the plan fiduciary.9Office of the Law Revision Counsel. 29 USC 1108 – Exemptions From Prohibited Transactions The Department of Labor’s regulations require this information to go to the plan in writing before the contract is signed and specifically name Rule 12b-1 fees as compensation that must be identified.10eCFR. 29 CFR 2550.408b-2 – General Statutory Exemption for Services or Office If you’re in a 401(k) or similar plan, your annual fee disclosure should show whether trailing commissions are being paid and in what amounts.
Tax Treatment
Because trailing commissions sit inside a fund’s expense ratio rather than being billed to you, there is nothing to deduct on your tax return. Before 2018, investors could sometimes deduct investment advisory fees as miscellaneous itemized deductions subject to a 2% adjusted gross income floor. The Tax Cuts and Jobs Act of 2017 suspended that deduction through 2025, and the One Big Beautiful Bill Act signed in 2025 made the elimination permanent. The cost of a trailing commission comes straight out of your after-tax wealth.
How to Reduce or Eliminate What You Pay
Once you know your rate, you have a few practical options:
- Switch share classes. If you hold Class C shares and your fund family offers Class A or an institutional share class with lower 12b-1 fees, converting can drop your trail from 1.00% to 0.25% or less. Ask whether your broker-dealer allows share class exchanges and whether a conversion would trigger a taxable event.
- Move to no-load funds or ETFs. Index mutual funds and exchange-traded funds generally carry no 12b-1 fees. A broad index fund with a total expense ratio of 0.03% to 0.10% removes trailing commissions from the picture.
- Work with a fee-only adviser. Fee-only advisers charge you directly, as a flat fee, an hourly rate, or a percentage of assets, and do not accept trailing commissions or other product-based compensation. The advisory fee still has to be weighed against the cost of a commission-based arrangement, but the product conflict is gone.
One thing to watch when you change advisors: trailing commissions on your existing holdings do not stop automatically. The new advisor or broker-dealer usually has to be designated as the broker of record on the account for the trail to redirect, and until that paperwork clears, your previous advisor may keep receiving it. Ask your new advisor to confirm the broker-of-record change has gone through.
