Restricted entity list checks to run before introducing a client for a referral reward

A restricted entity list independence check confirms, before a CPA introduces a client in a way that could earn a referral reward, whether the firm attests for that company or its affiliates. AICPA ET 1.520 bars commissions where the firm performs audit, review, certain compilation or prospective financial information examination services, and permitted referral fees must be disclosed.

Why this check comes before every introduction

A restricted entity list is the firm's record of attest clients and related entities in which partners and staff may not hold financial interests. Searching it before a partner introduces a client to SourceX answers one question quickly: does the firm attest for this company or an affiliate? If the firm audits or reviews the company, the commissions rule takes the reward off the table; if the hit is an affiliate or a compilation engagement, the independence team decides.

The rule behind the check is the AICPA Code's Commissions and Referral Fees Rule (ET 1.520). A member in public practice may not accept a commission for recommending a product or service to a client when the member or the member's firm also performs an audit, review, certain compilations or an examination of prospective financial information for that client, and any commission or referral fee that is permitted must be disclosed to the client (AICPA Code of Professional Conduct). Two further layers can apply:

The checklist

Before you search

  • Get the company's exact legal name, plus trade names and former names.
  • List its parent, subsidiaries and sister companies under common control, including a private equity owner's other portfolio companies if your independence policy treats them as affiliates.
  • Note which partner holds the relationship and which service lines serve the client today.
  • Hold any conversation with the owner about SourceX until the check is complete.

Search the list and the engagement system

  • Search the restricted entity list for the company and every related entity, and save the dated result.
  • Search the engagement or practice management system for current audit, review, compilation and prospective financial information engagements.
  • Check proposals and unsigned engagement letters, since a pending attest engagement changes the answer.
  • If the firm belongs to a network or runs separate attest and advisory entities, search the lists covering those entities too.
  • Search SourceX's legal name to confirm the counterparty is not itself a restricted entity.

Apply the rules

  • If the firm performs an audit, review, covered compilation or prospective financial information examination for the client, record that no reward will be accepted.
  • If the client or an affiliate is an SEC registrant the firm audits, ask the independence team to apply SEC rules as well.
  • Read the commissions and referral fee rule in every state where the engagement partner is licensed.
  • Check the firm's own referral-fee policy, which may go further than both.

Decide and document

  • Record the result, the date, who ran the search and who approved the outcome.
  • Where a reward is permitted, prepare the written disclosure for the client before the introduction.
  • Get the owner's approval to be introduced, and decide who in the firm registers it.
  • Diary a second search before any reward is accepted.

Why a second search before payout matters

Rewards become payable only after the buyer pays and SourceX receives its fee. Between an introduction and any payment, the company works through qualification, a data inventory, pricing, buyer review, contracting and delivery, which can take months. Attest relationships can change in that time: a new audit engagement, a lender that starts requiring reviewed statements, or a merger that brings in a firm already auditing the company. The guide to what happens when a CPA firm acquires a fractional CFO firm shows how a deal can move a client onto a new restricted list on closing day.

For reference, the program terms are simple. Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. Rewards become payable only after the buyer pays and SourceX receives its fee, and no reward is guaranteed. Any reward comes out of SourceX's share, leaving the company's licensing proceeds unchanged.

Red flags that stop the introduction

  • The search was run from memory or from an outdated export of the list.
  • A partner mentioned a reward to the owner before the check was done.
  • The company's lender or investors rely on reviewed or audited statements the firm prepares, or is proposing to prepare.
  • The introduction would be registered by a subcontractor or white-label provider who cannot see the firm's list; the subcontractor agreement guide covers who should register in that case.
  • Two partners plan to register the same company. Credit attaches to one referrer only, the first valid one, and only if a verified company application follows within the attribution window.

A clean search says nothing about fit. Fit is a separate test: 50+ full-time employees at peak (contractors excluded), operations documented across several years, the right to license what the company holds and a sponsor authorized to sign. Run the company fit checker and read the who qualifies baseline.

Next step

Add this checklist to your firm's referral procedure, or to the approval packet described in the alliance program review guide. Once a client clears, register as a partner and share your referral link with the owner.

Common questions

Is a restricted entity list the same as the firm's client list?

No. The restricted entity list covers attest clients and related entities where independence limits apply, mainly to personal and firm financial interests. The client list also includes tax, advisory and CAS clients that are not restricted. A referral check needs both: the restricted list to spot attest relationships, and the engagement system to see every service the firm currently provides.

Does the check need to cover the client's parent and sister companies?

Search them, then let the independence team decide what a match means. Firms differ in how their independence policies treat affiliates, and private equity ownership can link one client to many sister companies. A match on a related entity does not automatically rule out a reward, but it should never be resolved by the partner who would benefit from the answer.

Can a firm accept a reward for introducing a tax-only client?

The AICPA commissions restriction is tied to audit, review, certain compilation and prospective financial information examination services, so a tax-only client may fall outside it, subject to written disclosure. State rules can be stricter, and firm policy may go further than either. Confirm with your independence team and your state board's rule before registering the introduction.

What should a written referral-fee disclosure to the client say?

Name SourceX, explain that the firm or partner may receive a referral reward calculated as a share of SourceX's own fee, state that the reward is never deducted from what the company receives, and note that it is payable only if a deal closes and the buyer pays. Avoid projecting dollar amounts, and have the owner acknowledge the disclosure before the introduction is made.

What can the firm do for an audit client that wants to explore data licensing?

The owner is free to use the public application at sourcex.si/apply with no referral attached, and the firm takes no reward. Whether the audit team should be involved in the client's licensing decisions at all is a separate independence question about management responsibilities, so ask your independence team before offering anything beyond pointing the owner to the public application.
