A “tax shelter” is (1) any enterprise, other than a C corporation, if at any time interests in the enterprise have been offered for sale in an offering required to be registered with any federal or state securities agency, (2) any farming enterprise other than a C corporation that allocates more than 35 percent of its losses during any period to investors who do not actively take part in the management of the operation, or (3) any enterprise a significant purpose of which is tax avoidance.3
The following types of corporations engaged in farming are exempted from the above capitalization rules (if not otherwise deemed to be “tax shelters”): (1) S corporations and (2) corporations meeting certain gross receipts tests. A corporation meets the gross receipts test if its annual gross receipts for the three prior tax years do not exceed $31 million in 2025.
So long as a partnership (provided it is not deemed to be a “tax shelter”) does not have a non-exempt corporation as a partner, it will not be subject to the above capitalization rules.4
