Under Circular 230, which statement correctly describes what makes a practitioner's fee a contingent fee subject to the Section 10.27 restriction?
- AA fee is contingent only when it is expressed as a flat percentage of the refund obtained, so an hourly engagement that the client agrees to pay solely if a refund is secured falls outside the contingent-fee rule.
- BA fee is contingent whenever the practitioner and client agree on the amount after the engagement concludes rather than at the outset, because deferring the fee figure ties it to the eventual result of the matter.
- CA fee is contingent only where the client has no obligation to pay anything unless the Service issues a refund, so any arrangement requiring a minimum non-refundable retainer is excluded from the definition entirely.
- DA fee is contingent if it is based, in whole or in part, on whether a position avoids challenge by the Service or is sustained, and the term includes a fee the practitioner agrees to refund or reimburse if the matter is not resolved in the client's favour. Correct
Why A is wrong: A percentage of the refund is the obvious case, but Section 10.27 defines a contingent fee by its dependence on the result obtained, so an hourly fee payable only on success is still contingent; limiting the rule to percentages understates it.
Why B is wrong: Setting the figure later feels like it links pay to outcome, but Section 10.27 keys on whether the fee depends on the result, not on the timing of agreeing the amount, so a late-set fixed fee is not automatically contingent.
Why C is wrong: A pure no-win-no-fee deal is clearly contingent, but Section 10.27 also reaches fees based only in part on the result, so attaching a small retainer does not remove an outcome-based fee from the definition.
Why D is correct: Section 10.27 defines a contingent fee as one based in any part on whether a position is sustained or avoids challenge, and expressly includes a fee that is refundable or reimbursable depending on the outcome; this captures the full definition.
