How is the 280G base amount calculated?

Base amount = average W-2 compensation for 5 taxable years preceding the change in control. Parachute payments = all CIC-contingent payments (severance, accelerated vesting, bonuses). Excess parachute = parachute - base amount. Excise tax = 20% on excess; corporation loses deduction on excess.

What is the 2.99x safe harbor for 280G?

If total parachute payments are less than 3x the base amount, no excise tax applies. Companies often structure CIC payments to cap just below the 3x threshold (the '280G safe harbor'). Alternatively, disinterested shareholder approval of payments above 2.99x can eliminate the excise tax.
