SECTION 4. PROCEDURE

.01 General. (1) Additional disclosure of facts relevant to, or positions taken with respect to, issues involving any of the items set forth below is unnecessary for purposes of reducing any understatement of income tax under section 6662(d) (except as otherwise provided in section 4.02(3) concerning Schedules M–1 and M–3), provided that the forms and attachments are completed in a clear manner and in accordance with their instructions.

(2) The money amounts entered on the forms must be verifiable, and the information on the return must be disclosed in the manner described below. For purposes of this revenue procedure, a number is verifiable if, on audit, the taxpayer can prove the origin of the amount (even if that number is not ultimately accepted by the Internal Revenue Service) and the taxpayer can show good faith in entering that number on the applicable form.

(3) The disclosure of an amount as provided in section 4.02 below is not adequate when the understatement arises from a transaction between related parties. If an entry may present a legal issue or controversy because of a related-party transaction, then that transaction and the relationship must be disclosed on a Form 8275, Disclosure Statement, or Form 8275–R, Regulation Disclosure Statement .

(4) When the amount of an item is shown on a line that does not have a preprinted description identifying that item (such as on an unnamed line under an “Other Expense” category) the taxpayer must clearly identify the item by including the description on that line. For example, to disclose a bad debt for a sole proprietorship, the words “bad debt” must be written or typed on the line of Schedule C that shows the amount of the bad debt. Also, for Schedule M–3 (Form 1120), Part II, line 25, Other income (loss) items with differences, or Part III, line 35, Other expense/deduction items with differences, the entry must provide descriptive language; for example, “Cost of non-compete agreement deductible not capitalizable.” If space limitations on a form do not allow for an adequate description, the description must be continued on an attachment.
