Working With a Representative
What an Ethical Tax Professional Will Not Do for You, Even If You Ask
By Darrin T. Mish, Attorney · 5 min read · October 9, 2026
The short answer
A good representative fights for you inside the rules. Circular 230 bars practitioners from giving false information to the IRS, filing frivolous or delay-only submissions, helping evade tax, or trying to influence IRS employees improperly. If someone offers to cross those lines for you, they will cross them against you too.
Every so often a prospective client asks me, in a lowered voice, whether I can "leave something off" a financial statement, or "just not mention" an account. The answer is no. Not because I am squeamish, but because it is against the rules that govern my practice, and because it is the fastest way to turn a civil tax problem into a much worse one.
This chapter lays out the lines an ethical tax professional will not cross. Knowing them helps you in two ways. You will not waste time asking. And you will recognize the danger when someone offers to cross them for you.
No false or misleading information to the IRS
Circular 230 section 10.51(a)(4) lists as disreputable conduct giving false or misleading information, or participating in giving it, to the Treasury Department or any tribunal deciding federal tax matters, knowing it to be false or misleading. The regulation says "information" includes testimony, returns, financial statements, affidavits, declarations, and any other document or statement, written or oral.
Section 10.22 adds a duty of due diligence in determining the correctness of oral or written representations a practitioner makes to the Treasury Department and to clients.
In practice, that means your representative will not sign or submit a financial statement they know is wrong, will not tell a revenue officer something they know is untrue, and will ask you hard questions to make sure what they submit is accurate. That is not distrust. It is the job.
No frivolous positions or delay-only filings
Section 10.34(b) says a practitioner may not advise a client to take a position on a document, affidavit, or other paper submitted to the IRS unless the position is not frivolous. It also says a practitioner may not advise a client to submit a document, affidavit, or other paper whose purpose is to delay or impede the administration of federal tax laws, or that is frivolous.
For tax returns, section 10.34(a) bars practitioners from willfully, recklessly, or through gross incompetence signing a return, or advising a position on a return, that lacks a reasonable basis or is an unreasonable position under the preparer penalty rules of section 6694 of the Code.
So a representative will not file paperwork just to buy time with no legitimate basis, and will not push tax-protester theories. If someone promises to "tie the IRS up in paperwork," they are describing conduct the rules prohibit.
No help evading tax
Section 10.51(a)(7) lists willfully assisting, counseling, or encouraging a client to violate any federal tax law, or knowingly counseling an illegal plan to evade taxes or their payment.
That covers obvious things like hiding income. It also covers moving assets to defeat collection in a way the law treats as evasion of payment. A representative can and should advise you about lawful options, including which assets are exempt from levy and how to structure a legitimate resolution. They cannot help you hide.
No improper influence on IRS employees
Section 10.51(a)(9) prohibits attempting to influence the official action of an IRS employee through threats, false accusations, duress, coercion, special inducements, promises of advantage, or gifts and favors. Section 10.51(a)(5) prohibits implying the ability to obtain special consideration improperly.
Your representative will be firm, persistent, and sometimes blunt with the IRS. They will not try to buy, bully, or charm their way past the rules. The only legitimate edge is knowing the procedures better and preparing a better case.
No pocketing your refund
Section 10.31 says a practitioner may not endorse or negotiate any check issued to a client by the government for a federal tax liability, including by directing or accepting payment into an account the practitioner or the practitioner's firm controls. The Form 2848 instructions repeat the point.
Section 10.51(a)(8) makes it disreputable conduct to misappropriate, or fail to promptly remit, money a client gave for paying taxes. Together these rules are why I tell clients to pay the IRS directly. See never pay the IRS through your representative.
They will tell you things you do not want to hear
Section 10.21 requires a practitioner who learns that a client has not complied with the tax laws, or made an error or omission in something filed, to advise the client promptly and explain the consequences.
So if your representative finds an unreported account or a year you did not mention, they are required to tell you about it and what it means. What happens next depends on the facts, and it is a conversation you want to have with someone whose communications are protected. The privilege question is in tax privilege compared.
They will answer lawful IRS requests
Section 10.20(a) requires a practitioner, on a proper and lawful request by an authorized IRS employee, to promptly submit records or information in any matter before the IRS, unless the practitioner believes in good faith and on reasonable grounds that the records or information are privileged.
This is why privilege matters, and why the kind of professional you hire matters when facts are sensitive. It is also why the honest answer to "can you keep this from the IRS?" depends on what "this" is and whether a privilege applies, not on how much you are willing to pay.
They will not promise you a result
This one is not a single regulation, but it runs through everything. The FTC's consumer advice states that no company can promise a particular result. Section 10.30 bars practitioners from false, misleading, or deceptive advertising and solicitation. Section 10.51(a)(5) treats false or misleading representations to get clients as disreputable conduct.
An ethical professional will tell you what is likely, what is possible, and what it depends on. They will not tell you what the IRS will definitely do.
What they will do instead
None of these limits means your representative is on the IRS's side. Inside the rules there is a lot of room to fight. A good professional will challenge assessments that are wrong, insist on the procedures the IRS must follow, argue for every allowable expense, press penalty relief where the facts support it, and use appeal rights when the IRS says no.
They will also protect you from yourself. That might mean telling you not to speak to an agent alone, or to correct a return before the IRS finds the problem, or to stop moving money around while a collection case is open. Hard advice, delivered early, is part of the service. The what representation actually does chapter describes the work inside the lines.
A test you can run in the first meeting
If you want to know whether a professional will hold the line, listen to how they answer questions about the gray areas. Ask what they would do if they found an account you forgot to mention. Ask whether they would ever file something just to buy time. Ask whether they can promise a result.
The right answers are clear: they would tell you and explain the consequences, they would not file anything without a legitimate basis, and they cannot promise a result. A professional who hedges on those questions in a sales meeting will hedge on them later, under pressure, with your case on the line.
The bottom line for buyers
When you interview professionals, you are not looking for the one who will do anything. You are looking for the one who knows exactly what they will and will not do, and can explain why. That clarity is what keeps a hard case from turning into a disaster.
Why these limits protect you
The line, and what crossing it would cost you
| What you might ask for | Why a professional refuses | What could happen to you |
|---|---|---|
| Leave an asset off the financial statement | False information to the Treasury, section 10.51(a)(4) | A rejected resolution and potential penalties or worse |
| File something just to buy time | Delay-only or frivolous submissions, section 10.34(b) | Lost credibility and wasted fees |
| Route your refund through the firm | Section 10.31 | Your money in someone else's account |
| Promise the outcome | Misleading representations, section 10.51(a)(5) | Decisions based on a fantasy |
A professional who will cross a line for you will cross one against you. The ones who refuse are the ones you can trust with your money and your story.
