First let us calculate taxable income of the company, which is = gross income - expenses
= 1,250,000 - (20,000 - 58,000 - 600,000 - 150,000 - 90,000)
= $ 332,000
Tax payable = Tax rate * taxable income
Assuming the standard tax rate, which is 34%, company's net tax liability is = 0.34 * 332,000 = $112,000
