Five rule sets, one return
A first-year tax associate who prepares a Form 1040 is working under at least five overlapping rule sets at once. Each comes from a different authority, carries a different sanction, and asks a different question about the same work.
| Rule set | Source | Enforced by | What it asks |
|---|---|---|---|
| Circular 230 | 31 CFR Part 10 | IRS Office of Professional Responsibility | Did the practitioner act competently, diligently and honestly? |
| Preparer penalties | IRC 6694, 6695 and related sections | IRS examination | Did the preparer take an unsupported position or skip a required step? |
| Confidentiality | IRC 7216, 6713 and Reg. 301.7216 | IRS and the Department of Justice | Was return information used or disclosed without consent? |
| E-file rules | Pub. 3112, Pub. 1345, IRC 6011(e)(3) | IRS e-file program | Is the firm an authorized provider meeting program rules? |
| Professional standards | AICPA Statements on Standards for Tax Services | AICPA and state boards | Did the member meet the profession's standard of care? |
State boards of accountancy add their own conduct rules for licensees, and the FTC Safeguards Rule adds data security duties. Those come up in the last lesson of this track.
Conduct rules versus penalties
Circular 230 is a set of conduct rules. A violation leads to censure (a public reprimand), suspension, disbarment from practice before the IRS, or a monetary penalty under section 10.50. It does not produce a tax bill.
The Code penalties are civil money penalties assessed against the preparer. Section 6694 targets understatements caused by unreasonable positions or willful or reckless conduct. Section 6695 targets procedural failures such as not signing, not furnishing a PTIN, or not meeting due diligence on refundable credits. The amounts in 6695 are adjusted for inflation each year.
Some provisions are criminal. Section 7216 makes knowing or reckless disclosure or use of return information a misdemeanor, with a fine of up to $1,000 and up to one year in prison. Section 6713 is the civil counterpart for the same conduct.
One set of facts can trigger all three. A preparer who invents business expenses to inflate a refund can face a 6694(b) penalty, a Circular 230 referral and, at the extreme, prosecution.
Why staff are covered
Section 10.8(a) of Circular 230 says any individual who for compensation prepares or assists with all or substantially all of a tax return must have a PTIN and is subject to the duties in subpart B and the sanctions in subpart C. Section 7701(a)(36) of the Code defines a tax return preparer to include a person who prepares a substantial portion of a return for compensation, so a non-signing preparer can be liable under section 6694. The IRS PTIN guidance says anyone you hire to prepare returns needs a PTIN regardless of whether you review and sign the returns. Being junior does not take you outside the rules.
Where each rule bites in the workflow
- Engagement and intake: conflicts check (10.29), section 7216 consents, engagement letter terms.
- Preparation: diligence (10.22), reliance on client information and reasonable inquiries (10.34(d)), Form 8867 knowledge requirement for refundable credits.
- Review and signing: position standards (10.34 and 6694), penalty and disclosure advice to the client (10.34(c)), client copy no later than when the return is presented for signature (6107(a)).
- Filing: Form 8879 signature authorization, e-file mandate.
- After filing: retention of the copy or list (6107(b)), Form 8867 records, return of client records (10.28), data security.
The tax season workflow guide shows how a firm sequences these steps. The rest of this track takes each rule in turn, starting with Circular 230 scope.
One error, three rule sets: Lena at Harbor Row Tax
Lena, a second-season associate at Harbor Row Tax, prepares a 2025 Form 1040 for a rideshare driver. The client's organizer lists $41,000 of gross receipts and $29,000 of vehicle expenses with no mileage log. Lena enters the expenses as given, the senior signs, and the return is e-filed.
On examination the IRS disallows $22,000 of the expenses for lack of substantiation.
Rule set 1, section 6694: the senior signed and Lena prepared a substantial portion. If there was no substantial authority for claiming undocumented expenses and no reasonable cause, the IRS can assess the greater of $1,000 or 50 percent of the income the preparer derived from the return.
Rule set 2, Circular 230: section 10.34(d) allows good-faith reliance on client information, but requires reasonable inquiries when information appears incorrect or incomplete. Expenses at 71 percent of receipts with no log called for questions. Section 10.22 diligence is also in play.
Rule set 3, AICPA standards: if the signer is an AICPA member, SSTS 2.3 also calls for reasonable inquiry when client information appears incorrect, incomplete or inconsistent. The file shows none, so the firm's quality review flags it.
Conclusion: the fix is the same for every rule set. Ask for the mileage log, document the answer in the workpapers, and keep the note with the return.
Self-check
Answer each question before you open the answer.
Which body enforces Circular 230, and what sanctions can it impose?
Show answer
The IRS Office of Professional Responsibility. Under section 10.50 a practitioner can be censured, suspended or disbarred from practice before the IRS, and a monetary penalty can be imposed.
Is a staff member who prepares a return but never signs it covered by the preparer rules?
Show answer
Yes. Section 10.8(a) covers anyone who for compensation prepares or assists with all or substantially all of a return, and IRC 7701(a)(36) includes a person who prepares a substantial portion of a return. The IRS says hired preparers need a PTIN even when someone else reviews and signs.
Name a criminal provision and a civil provision that both address misuse of return information.
Show answer
IRC 7216 is the criminal misdemeanor provision. IRC 6713 is the civil penalty for the same unauthorized disclosure or use.
