Commissions and referral fees

Commissions and referral fees are payments for recommending or selling a product or service, and the AICPA Code bars them for attest clients and requires disclosure to the client where they are permitted.

CORAA TeamUpdated November 5, 2026

Definition

A commission is compensation, other than a fee for a professional service, for recommending or referring a product or service to a client. A referral fee is a payment for referring a client or work. Under the Commissions and Referral Fees Rule (ET 1.520.001), a member in public practice may not accept a commission for recommending a product or service to a client for whom the member or the firm performs an attest engagement. Where a commission or referral fee is permitted, the member discloses acceptance or payment to the client. State boards of accountancy often add their own limits.

Why it matters in an audit or review

A commission on a product sold to an attest client gives the firm a financial stake in a recommendation, which creates a self-interest threat to objectivity. Reviewers test whether firm policies prohibit such fees for attest clients and whether disclosures were made for others.

Example

Illustrative: a firm audits a manufacturer, and an insurance broker offers the firm a percentage of premiums if it recommends the broker. The firm declines, since accepting would breach the Code. For a tax-only client, the firm could accept a permitted commission only after telling the client in writing.

Common mistakes

  • Treating a marketing partnership or revenue share as outside the rule.
  • Assuming a client's consent removes the prohibition for attest clients.

Related terms

  • Contingent fees
    A contingent fee depends on a finding or result, and the AICPA Code and IRS Circular 230 each restrict such fees in specified situations, including for attest clients and for tax returns.
  • Independence
    Independence for an auditor means independence of mind and independence in appearance. It is required for audits and reviews, and under the AICPA Code it is judged using a conceptual framework.
  • Objectivity and integrity
    Objectivity and integrity are two principles in the AICPA Code. Objectivity is impartiality and freedom from conflicts of interest. Integrity means being honest and candid, without subordinating judgment to others.
  • Threats and safeguards
    Threats are circumstances that could compromise compliance with the AICPA Code, and safeguards are actions that reduce them to an acceptable level. If none works, the member declines or stops.
