What is Built-in gains tax?

In short

The built-in gains tax is a corporate-level tax on an S corporation that was formerly a C corporation, imposed when it sells assets that had unrealized gains at the date it converted, within the recognition period.

Key takeaways

  • The recognition period is five years after the S election takes effect.
  • It prevents C corporations from avoiding corporate tax by electing S status just before a sale.
  • It is taxed at the highest corporate rate.
