C Corp Formation: §351, Stock Issuance, Controlled Groups

Free IRS Enrolled Agent SEE Part 2 (Businesses) lesson in Business Entities and Considerations. 21 min read, ~3,154 words.

Three friends pool a building, a patent, and legal services into a new C corporation, expecting tax-free treatment under §351. Two qualify, one walks away with $50,000 of ordinary compensation income, and a missed 80% control test would have made the entire transaction a taxable sale. The rules below decide who pays and who defers.

A corporation comes into existence under state law when articles of incorporation are filed with the secretary of state. For federal tax purposes, the entity is a C corporation by default from its date of incorporation. Three formation steps:

The corporation obtains an EIN on Form SS-4, elects a tax year on its first Form 1120, and may file Form 2553 within 2 months 15 days of the start of the desired tax year to elect S status.

Common mistakes

Bottom line

Exam shortcut

Control test first. Count only stock issued for property when checking 80%. If service-provider shares break 80%, the entire transaction is taxable as a sale. Boot gain formula: LESSER of realized gain or boot FMV. Then add §357(c) excess separately. They stack, they do not offset. Brother-sister attribution skips siblings. If the only common ownership is sibling-to-sibling, there is no controlled group.
