Exception: Fees for audit defense or amended returns may be contingent.

1. General Rule: Contingent Fees Are Banned

  • Original tax returns: Preparers cannot charge fees based on:

    • Refund size (e.g., "10% of your refund").

    • Tax savings (e.g., "Pay us 20% of what we save you").

  • Why?  Prevents conflicts of interest (e.g., inflating deductions to boost fees).

Example (Prohibited):

❌ "Our fee is 15% of your refund!" → Banned for preparing a Form 1040.


2. Exception: Audit Representation & Other Special Services

The only allowed contingent fees are for:

  • Audit defense (IRS examinations).

  • Amended returns (e.g., filing Form 1040-X to correct errors).

  • Court appeals (e.g., Tax Court cases).

Example (Allowed):

✅ "We’ll charge 25% of the tax savings if we successfully defend your audit." → Permitted.


Key IRS Source: Circular 230, Section 10.27

  • Bans contingent fees unless for:

    • IRS examinations (audits).

    • Original returns where the fee is fixed by court order (rare).


Why This Matters for Exams

  • Contingent fees = Always wrong for original tax returns.

  • Exception = Audit/amended return work.

Exam Tip: If a question mentions "percentage of refund," ask:

  • Is this for preparing a return? → Illegal.

  • Is this for audit defense? → Legal.
