Brokerage Window

DC / ERISAUpdated July 2026

Definition

A brokerage window is a feature of some defined contribution plans that permits participants to invest a portion of their account outside the plan's core investment menu through a self-directed brokerage account, which typically provides access to a broader universe of mutual funds, exchange-traded funds, and individual securities than the core menu offers.

Why it matters

A brokerage window changes the shape of the participant's choice set: alongside the core menu selected by the plan fiduciary, the participant gains access to a much larger investment universe through a self-directed account. This expansion sits alongside a distinctive fiduciary framing in which the Department of Labor's guidance treats plan fiduciary responsibility as attaching to selection of the brokerage window feature itself and its provider, without extending to the individual securities a participant selects through the window.

How it works

A brokerage window is typically offered through a specific brokerage provider that the plan fiduciary selects. Participants who elect to use the window transfer some portion of their plan balance into a self-directed brokerage account associated with their plan participation, and from there can invest in the broader universe of options the provider makes available — usually mutual funds and exchange-traded funds, sometimes individual stocks and bonds, sometimes options and other more specialized instruments depending on the provider's platform. The plan document typically imposes limits: a maximum percentage of the participant's plan balance that can be held in the window, minimum transfer amounts, and restrictions on certain instruments. The window may charge participants a fee separate from the plan's core recordkeeping and investment charges. The Department of Labor's Field Assistance Bulletin 2012-02 and subsequent guidance have clarified that the plan fiduciary retains prudence duties in the selection of the brokerage window feature and provider, but that fiduciary duty does not extend to a review of every specific investment participants make within the window.

In practice

For an individual participating in a defined contribution plan that offers a brokerage window, the window is an option available in addition to the core investment menu — not a replacement for it. A participant using the window takes on the responsibility of selecting and monitoring individual investments outside the plan's fiduciary-selected menu; the window does not carry the same layer of fiduciary review that the core menu does. Participants who use the window typically pay a window-specific fee and may pay transaction-level costs on individual trades depending on the provider's fee structure. A professional advising a participant considering the window can help evaluate whether the individual investments the participant intends to select through the window are appropriate for the participant's total-portfolio circumstances, and can help the participant understand what shifts from the fiduciary to the participant when the window is used.
