Key exceptions to the rules.

The tax code provides a couple notable exceptions to the imputed interest rules:

Gift loans of less than $10,000 are exempt, as long as the money isn’t used to buy income-producing assets.
Compensation-related and corporation-shareholder loans under $10,000 are also exempt if the lender can demonstrate that tax avoidance wasn’t the purpose of the loan.
