Is The Mather Group a Fiduciary? What Its Own Form CRS Says (2026)

Guides › Financial Advisor Fees

Updated September 28, 2026. Quick answer: Yes, on every account. The Mather Group is registered with the SEC only as an investment adviser (it is not a broker-dealer), so the Investment Advisers Act of 1940 requires it to act as your fiduciary. Its own Form CRS states: “When we act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours. That means we are required to act in your best interest throughout our entire advisory relationship.”

How it’s registered

From Form CRS, Customer Relationship Summary, The Mather Group (February 2, 2026): “THE MATHER GROUP, LLC (“TMG”) is registered with the Securities and Exchange Commission as an investment adviser.”

The standard of conduct, in its own words

“When we act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours. That means we are required to act in your best interest throughout our entire advisory relationship.”

On commissions: “The firm’s revenue is derived from the advisory fees that we collect from your account. We do not receive compensation for the sale of securities to our clients.”

What this means for what you pay

Fiduciary status is one input, not the whole picture. The Mather Group discloses a published fee that runs $5,750 a year on a $500,000 account; see the full dollar breakdown from The Mather Group’s own fee disclosure before deciding whether the standard of conduct here changes your answer.

If the answer above changes your mind about staying, read the general mechanics of switching financial advisors, or use a dated termination letter once you decide.
