Work Step by Step

Gross income is the income from wages, tips, interest or dividends from investments, unemployment compensation, profits from a business, rental income and even game show winnings. To compute Gross Income, the following formula can be used: \[\begin{align} & \text{Gross}\ \text{Income}=\ \text{Wages}+\text{Interest} \\ & \ \text{= }\!\!\$\!\!\text{52,600+}\!\!\$\!\!\text{720}\\&\text{=}\!\!\$\!\!\text{53,320}\end{align}\] For calculating the gross income, wages, interest have been added. Adjusted gross income is figured by taking gross income and subtracting certain allowable amounts, known as adjustments. These untaxed portions of gross income include contributions to certain retirement accounts and tax-deferred savings plans, interest paid on student loans and alimony payments. To compute adjusted gross income, the following formula can be used: \[\begin{align} & \text{Adjusted}\ \text{Gross}\ \text{Income}=\ \text{Gross}\ \text{Income}-\text{Adjustments} \\ & =\ \$53,320-\$3,200\\&=\\$50,120\end{align}\] Adjustable gross income is figured by subtracting adjustments from gross income. Taxable income is the amount of income used to calculate how much tax an individual owes to the government in a given tax year. To compute taxable income, the following formula can be used: \[\begin{align} & \text{Taxable Income = Adjusted Gross Income}-\left( \text{Exemptions}+\text{Deductions} \right) \\ & =\$50,120-\left(\$3,800+\$7,250\right)\\&=\$39,070\end{align}\] Taxable income is figured by subtracting adjustments and deductions from adjusted gross income.
