1

IRC 61, Gross Income Defined. As a general rule, all income is taxable unless proven otherwise.

2

IRC 102, Gift and Inheritances. As a general rule, gross income does not include the value of property acquired by gift, bequest, devise, or inheritance. *See also: Synanon Church v. Commissioner, T.C. Memo. 1989-270 (Docket No. 20015-84). See Exhibit CPE 1990, Taxation of Revoked Tax-Exempt Organizations: The Synanon Case, and General Counsel Memorandum 39813. (Not citable as legal precedent)

**

Issues Examiner should consider:

Was there a good faith solicitation?

Was there a good faith contribution?

3

Government Grants are not excludable income under IRC 102.

4

IRC 277, Deductions by Certain Membership Organizations [non 501(c)(3)]. As a general rule, deductions shall be allowed only to the extent of income derived during such year from members or transactions with members.

501(c)(3) - generally deductible

**

Examiners need to distinguish between contributions and gross receipts. Scenarios would be:

All classified as contributions with member benefits all deductible.

Quid-pro-quo - only partially contributions and only partially deductible.

Member services for member benefits - where no part is attributable to charitable purpose, would not be deductible.

5

IRC 470, Property Leased to an Exempt Organization. If a corporation leases property to a governmental or other tax-exempt entity, the corporation cannot claim deductions related to the property to the extent that they exceed the corporation's income form the lease payments.

6

IRC 162, Trade of Business Expenses. Examiners should be aware of the "Income Offset Rules" for deductibility of expenses.

7

IRC 263 and IRC 263A, Capital Expenditures. Generally requires corporations to capitalize, or include in inventory certain costs incurred in connection with real property and inventory. Please be aware that this section applies to Form 990 as well

8

IRC 183, Activities not engaged in for profit. As a General Rule, in the case of an activity engaged in by an individual or an S Corporation, if such activity is not engaged in for profit, no deduction attributable to such activity shall be allowed under this chapter [26 USCS §§ 1 et. seq.] except as provided in this section.
