**Single**and your income is $400,000 for 2011-2012. Let us go step by step to calculate your income tax.

A = 10% of $8,500 = $850

B = 15% of difference between $8,500 and $34,500 = 15% of $26,000 = $3,900

C = 25% of difference between $34,500 and $83,600 = 25% of $49,100 = $14,600

D = 28% of difference between $83,600 and $174,400 = 28% of $90,800 = $25,424

E = 33% of difference between $174,400 and $379,150 = 33% of $204,750 = $67567.50

F = 35% of difference between $379,150 and $400,000 = 35% of $20,850 = $7297.50

Total Income Tax on $400,000 = A + B + C + D + E + F
