Answer:
annual estimated taxable income = $370000
Step-by-step explanation:
given data 
taxable income first quarters = $119,000 
taxable income second quarters = $66,000 
taxable income third quarters = $106,250 
total first three quarters = $291,250
 
to find out 
annual estimated taxable income
solution
we get here annual taxable income so first we get here third quarter estimated payment
so for that we need annualize cumulative taxable income half year that is taxable income of 1st and 2nd quarters
so taxable income of 1st and 2nd quarters = $119,000 and $66,000 
so here annual estimated taxable income will be 
annual estimated taxable income = 2 × ( taxable income first quarters + taxable income second quarters ) .........1
annual estimated taxable income = 2 × ( $119000 + $66000 ) 
annual estimated taxable income = $370000
