A tax consultant meets a client who also needs an immigration lawyer, a wealth manager abroad, or a specialist CPA in another country. The consultant made the introduction happen. Can they get paid for it?
The short answer is usually yes, and that’s a meaningfully different answer than the one lawyers get under bar rules. Tax consultants and CPAs operate under a disclosure-first model, not an outright prohibition. This guide walks through exactly how that works, where it breaks down, and how to structure a referral fee that survives a state board inquiry.
Key Takeaways
- Under the AICPA Code of Professional Conduct, Section 1.520.001, CPAs can generally accept or pay referral fees as long as they disclose them to the client in writing.
- The major exception: a CPA cannot accept a referral fee or commission tied to a client for whom they also perform audit, review, or compilation services, due to independence rules.
- Disclosure has to happen before or at the time of the referral, not buried retroactively in an engagement letter.
- Non-CPA tax consultants (enrolled agents, unlicensed preparers) face a looser but less standardized rulebook, layered with Circular 230 conflict-of-interest duties for those who practice before the IRS.
- State boards of accountancy can add stricter disclosure or documentation requirements on top of the AICPA Code.
Referral fee rules for lawyers, tax advisors, and consultants
Can a Tax Consultant Legally Accept a Referral Fee?
Yes, in most cases. Under the AICPA Code of Professional Conduct, Section 1.520.001, “Referral Fees or Commissions,” a CPA can accept or pay a referral fee for recommending a client to another professional as long as the fee is disclosed to the client. This is a fundamentally different starting point than the one lawyers face.
Compare that to the legal profession, where ABA Model Rule 5.4 generally bars a lawyer from splitting fees with a non-lawyer at all. CPAs don’t operate under that prohibition. The AICPA Code treats a referral fee as permissible business activity, provided the client knows about it. Disclosure, not prohibition, is the operative principle.
In our experience talking with CPA firms and independent tax consultants who refer clients across borders, this distinction surprises people constantly. Consultants who’ve worked adjacent to lawyers often assume the same fee-sharing ban applies to CPAs, and structure referral relationships far more conservatively than the rule actually requires. That over-caution isn’t wrong, exactly, it’s just often unnecessary once written disclosure is in place.
The practical upshot: a tax consultant who refers a client to an immigration lawyer, a foreign wealth manager, or a specialist CPA can typically accept a flat fee, a percentage of the specialist’s fee, or an ongoing commission, as long as the client signs off on knowing about it. The specifics of what “knowing about it” needs to look like are covered in the next section.

What Does the AICPA Code Actually Require for Disclosure?
Section 1.520.001 of the AICPA Code of Professional Conduct requires a member who pays or receives a referral fee to disclose that fact to the client, in writing, before or at the time of the referral. A verbal mention after the fact generally does not satisfy the rule.
The disclosure needs to name the arrangement clearly enough that the client understands money changed hands because of the introduction, not just that an introduction happened. Best practice, and the approach most compliance-conscious firms take, is a short written statement: which party is paying the fee, which party is receiving it, and that the client’s decision to use the referred specialist is entirely their own.
We’ve reviewed referral disclosure language from a range of CPA firms and tax consultancies, and the ones that hold up best under scrutiny are short and specific. A single sentence, something like “our firm receives a referral fee if you engage [Specialist Name] for the services described,” tends to work better than a paragraph buried in a ten-page engagement letter. Clients notice specificity; they skim past boilerplate.
A signed client acknowledgment isn’t strictly mandated by the AICPA Code in every case, but it’s the safer practice. If a state board of accountancy or a peer reviewer ever asks for proof the disclosure happened, “the client signed this on this date” is a much stronger answer than “we mentioned it during a call.”
When a CPA Cannot Accept a Referral Fee From a Client
A CPA cannot accept a referral fee or commission tied to a client for whom the CPA also performs audit, review, or compilation services. This exception exists because the AICPA Code of Professional Conduct treats commission and referral-fee arrangements as a threat to independence for attest engagements specifically.
The logic is straightforward once you see it. An auditor is supposed to give an independent, unbiased opinion on a client’s financial statements. If that same auditor stands to earn a commission or referral fee tied to that client, financial self-interest creeps into a relationship that’s supposed to be free of it. The AICPA’s independence rules exist precisely to prevent that kind of conflict, and Section 1.520.001 defers to those independence standards for attest clients.
Among the accounting firms we’ve worked with on the MezAgent platform, this exception is one of the most commonly misunderstood parts of the referral rules. Several firms initially assumed the disclosure requirement alone was enough to clear any referral fee, audit client or not. It isn’t. When a firm performs an audit, review, or compilation for a client, the referral fee has to go away entirely for that engagement, not just get disclosed more carefully. We haven’t formalized this into published research, but the pattern of confusion has come up often enough that we now flag it explicitly with new firms joining referral networks.
In practice, this means a CPA firm that both audits a client’s financial statements and wants to refer that same client to a specialist, say, a cross-border tax attorney, needs to separate the two relationships cleanly. Either the referral fee is waived for that client, or the audit engagement moves to a different partner or firm entirely. Firms that skip this step risk both an independence violation and, in SEC-regulated engagements, a much more serious regulatory problem.

Does This Exception Apply to Tax-Only Engagements?
No, the independence exception is specific to audit, review, and compilation services, not general tax preparation or tax advisory work. A CPA who only prepares a client’s tax return, without also performing attest services for that client, can typically still accept a disclosed referral fee tied to that same client relationship.
That said, a CPA firm offering multiple service lines to the same client needs to track, service by service, whether an attest engagement exists anywhere in that relationship. A firm doing tax prep for one client and an audit for another can treat the two referral situations completely differently, even within the same office.
Do Non-CPA Tax Consultants Follow the Same Rules?
Not exactly. Enrolled agents, unlicensed tax preparers, and independent tax consultants who aren’t CPAs aren’t directly bound by the AICPA Code, but many of them practice before the IRS and fall under Circular 230, the Treasury regulation covering conflicts of interest and competence for tax practitioners.
Circular 230 doesn’t prohibit referral fees outright. It requires practitioners to avoid conflicts of interest and act with the diligence a client is entitled to expect. A referral arrangement that steers a client toward a worse-fit specialist purely because of a bigger kickback risks becoming a Circular 230 conflict-of-interest problem, separate from any disclosure question. The rule cares less about the fee itself and more about whether the advice given was actually in the client’s interest.
We’ve noticed a pattern among enrolled agents and independent consultants: because they’re not bound by a specific referral-fee disclosure rule like Section 1.520.001, some assume no disclosure obligation exists at all. That’s a risky read. Even without an explicit AICPA-style rule, an undisclosed fee that influences which specialist a client gets referred to can still expose a practitioner to a Circular 230 conflict-of-interest claim, and it erodes client trust regardless of the technical rule.
State boards also matter here. Several states regulate tax preparation and consulting activity independent of CPA licensure, and those state rules aren’t always identical to the AICPA Code or Circular 230. A consultant operating across state lines, which is common in cross-border and multi-state referral work, should check the specific rule in every state where clients are served, not assume one state’s rule travels with them.
Common Fee Structures Tax Consultants Actually Use
Most compliant referral arrangements between tax consultants and specialists fall into three structures: a flat one-time fee per referral, a percentage of the specialist’s fee on that engagement, or an ongoing reciprocal arrangement where both sides refer clients to each other over time. Each carries different disclosure and documentation weight.
A flat fee is the simplest to disclose and track: a fixed dollar amount paid once the referred client engages the specialist. A percentage-based fee, a share of the specialist’s first-engagement fee, requires more careful disclosure since the dollar amount isn’t fixed until the specialist’s engagement is priced. Reciprocal arrangements, where a tax consultant and, say, a cross-border immigration lawyer, refer clients back and forth, need to be non-exclusive and clearly disclosed on both sides to stay defensible.
In the referral networks we’ve observed, percentage-based fees generate more client questions than flat fees, simply because the number isn’t known upfront. Firms that lead with a flat, disclosed dollar amount tend to get fewer follow-up questions from clients and less friction during onboarding with the specialist. That’s an observational pattern from the relationships we’ve tracked, not a controlled study, but it’s consistent enough to be worth factoring into how a new referral relationship gets structured.
| Fee Structure | How It Works | Disclosure Complexity |
|---|---|---|
| Flat referral fee | Fixed dollar amount paid once the referred client engages the specialist | Low, the exact figure is known upfront |
| Percentage of specialist’s fee | A share of the specialist’s first-year or first-engagement fee | Moderate, exact amount depends on the specialist’s final pricing |
| Reciprocal referral arrangement | Two professionals refer clients to each other over time, often without cash changing hands per referral | Moderate to high, must stay non-exclusive and disclosed on both sides |
Documenting Referral Fee Arrangements: What to Keep on File
A defensible referral fee record includes four things: the referring party’s identity and license status, the fee structure agreed upon, the date and method of client disclosure, and a signed client acknowledgment. Without this, a state board or peer reviewer investigating a complaint has nothing but memory and email fragments to work from.
The safest practice treats disclosure as a point-of-referral event, not a clause buried in a broader engagement letter. A short, signed statement at the moment the referral happens (naming the specialist, the fee, and confirming the client’s choice is voluntary) creates a much cleaner record than a general “we may receive referral fees from time to time” line in a standard contract.
Across the referral relationships we’ve tracked on the MezAgent platform between tax consultants, CPA firms, and cross-border specialists, the arrangements that hold up best during later client or board scrutiny share one trait: the disclosure and the referral itself happen in the same document, on the same date. Firms relying on a standing engagement-letter clause from years earlier, disconnected from the specific referral, report more client pushback when the fee eventually comes up. This is an internal observation from the referrals we’ve watched move through the platform, not a formal audit finding, but it has shaped how we advise firms to set up disclosure workflows.
For consultants working across state lines or with cross-border specialists, adding a fifth tracking field, the specialist’s jurisdiction and licensing body, closes the gap that surfaces first in any multi-jurisdiction compliance review.
Frequently Asked Questions
Can a CPA get paid for referring a client to a lawyer?
Yes, generally. A CPA can accept a referral fee for referring a client to a lawyer or other specialist under the AICPA Code of Professional Conduct, Section 1.520.001, as long as the fee is disclosed to the client in writing before or at the time of the referral.
Is a tax consultant referral fee the same thing as a commission?
They’re closely related but not always identical terms. Section 1.520.001 of the AICPA Code covers both “referral fees” and “commissions” under the same disclosure requirement, so in practice, whichever term applies, the CPA must tell the client a fee changed hands.
What happens if a CPA doesn’t disclose a referral fee?
An undisclosed referral fee can trigger a professional conduct violation under the AICPA Code and expose the CPA to state board discipline. It can also void the practical enforceability of the referral arrangement and damage client trust if discovered after the fact.
Can a CPA accept a referral fee from an audit client?
No. A CPA cannot accept a referral fee or commission tied to a client for whom the CPA also performs audit, review, or compilation services, because of independence rules under the AICPA Code. The exception is specific to attest engagements, not general tax work.
Do enrolled agents follow the same referral fee rules as CPAs?
Not exactly. Enrolled agents aren’t bound by the AICPA Code, but many practice before the IRS and fall under Circular 230, which requires avoiding conflicts of interest rather than mandating a specific disclosure format.
Key Takeaways: Getting Paid to Refer Without the Compliance Risk
Tax consultants and CPAs operate in a more permissive referral-fee environment than lawyers do, but “more permissive” isn’t the same as “no rules.” The AICPA Code’s disclosure requirement under Section 1.520.001 is the baseline, and the audit, review, and compilation exception is the one place where disclosure alone won’t save an arrangement.
The through-line is the same one that runs across every profession covered in this cluster: put it in writing, disclose it before the client engages the specialist, and keep a signed record. For consultants managing referral relationships across state lines or across borders, that documentation habit is what separates a defensible fee arrangement from one that becomes a liability the first time a state board asks questions.
