The AB1290 reimbursement is calculated as follows:
Tier one (year 1 - Last fiscal year Agency receives tax increment) = 20% of Gross Tax Increment.
Tier two (year 11 - Last fiscal year Agency receives tax increment) = 16.8% of Gross Tax Increment in addition to Tier one. Year 10 is the adjusted base year.
Tier three (year 31 - Last fiscal year Agency receives tax increment) = 11.2% of Gross Tax Increment in addition to Tier one and two. Year 30 is the adjusted base year.
