Forming a corporation: Section 351

Transferring property to a corporation is tax-free under section 351 if the transferors own at least 80% of the voting power and 80% of each other class of stock immediately afterward; gain is recognized only to the extent of boot, and liabilities in excess of basis also trigger gain.

Worked example

Facts: Joe transfers land (basis $30,000, FMV $100,000) to a new corporation for 100% of the stock (worth $90,000) plus $10,000 cash.

Result: realized gain $70,000; recognized = boot $10,000. Joe’s stock basis = $30,000 + $10,000 - $10,000 = $30,000. Corporation’s land basis = $30,000 + $10,000 = $40,000.

Exam traps

  • The 80% test applies to all transferors as a group.
  • Losses are never recognized, even with boot.
  • Service providers are not “transferors” unless they also transfer property.
  • Liabilities over basis (357(c)) is gain even with no cash boot.
