Meaning
Corporate tax provisions evaluate whether transferors of property hold requisite equity ownership immediately after an exchange. The control group test requires that persons who transfer property to a corporation collectively own at least eighty percent of total voting power and eighty percent of all other stock classes immediately following the transaction. Satisfaction of this test permits founders and investors to defer tax recognition on appreciated assets contributed during formation.
Failure to meet the threshold converts an intended tax-free section 351 exchange into a fully taxable transaction.
Equity Calculation
Stock ownership counts toward the statutory threshold only when issued for tangible or intangible property rather than services. Transfers made solely in exchange for services do not qualify the recipient as a transferor for the control group test. When an existing shareholder contributes nominal property primarily to qualify service providers under the rule, tax authorities disregard that shareholder’s entire holdings.
Transfer Timing
Transaction steps executed under a single agreement are evaluated together to determine final ownership percentages. Simultaneous exchanges by multiple founders are treated as one integrated transaction under the control group test. If a transferor immediately sells stock pursuant to a pre-existing binding obligation, that stock is deducted from the qualifying control total.
Tax courts analyze whether the binding agreement existed before the property transfer occurred. Sequential stock issuances to incoming investors can break control if executed as part of an integrated financing plan.
Statutory Standard
IRS guidance requires explicit attribution rules when assessing voting power across multiple share classes. Voting power depends on the direct legal right to elect corporate directors rather than economic participation rights. The control group test applies strictly at the moment the property exchange concludes.
