After-Tax Income Explained

The after-tax income is the disposable income left with the businesses and individuals to be spent and invested in their future requirements. It is the difference between the gross income and the sum of the applicable deductions.

Before figuring out the after-tax earnings, individuals and businesses have to calculate the deductions applicable against the income generated. The individuals file taxes using the IRS Form 1040, which varies from individual to individual. Once the deductions are totaled, the same is subtracted from the gross income to obtain the disposable income, which is the income after taxes.

The income from various sources are considered for calculating the after-tax income. Therefore, earnings from each source gets added together to obtain the gross income with each source of income, along with the deductions, constituting the components of after-tax income.

This income can be the earnings generated from salary or anything received by renting or leasing out residential or commercial space. In addition, a business’s profits form the major part of the gross income.

The revenue from capital gains adds to the list of income generated. People receive this income by selling off capital assets. Though the gains are not regular, they form significant part of the income after taxes. In addition, these profits are of high value; hence, they also add to the income of both individuals or entities and the government.

When calculated for corporations, the income after taxes becomes the Net Income After Taxes (NIAT). However, NIAT includes finding the net income after deducting all expenses, including taxes, from gross income.

The net after-tax income can be calculated using the formula below:

After Tax Income=Gross Income-Applicable Taxes


Gross Income = Total of all income generated from different sources

Applicable taxes = Sum of all taxes applied, be it federal, state, local, or other taxes

In Canada, the net or monthly after-tax income is calculated using the formula below:

After Tax Income=Gross Income-Applicable Taxes/ Tax Payable


Tax Payable = [(Gross Income – Tax Deductions) * (Marginal Tax Rate) = Tax Credits]

Calculation Example

While the formula for calculating after-tax income is easy, it is tricky to calculate the value of the components of disposable income. The example below shows how it works:

Jonas computes his income as a singer and finds it to be worth $856 million for the FY 2018-19. He has several other incomes from interest on deposits, which adds up to $44 million. The taxpayer has let out one of his apartments in New York City and another in LA, from which he earns a total net taxable income of $109 million. He has also sold one of his apartments in Spain for $550 million (computed) to a Superstar in the Financial Year.

He has made an investment that is eligible for deductions from total taxable Income, adding up to $45 million. As a result, the total tax rate prevailing in his country becomes 15% of the net taxable income.

So, let us calculate the after-tax income for the taxpayer:

Below is the statement depicting Jonas’ income figures for the year 2018-19 under various income heads:

ParticularsAmount ($ millions)
Income from Salary
(+) Income from Profession856
(+) Income from House Party109
(+) Income from Other Sources44
(+) Income from Capital Gains550
Gross Total Income1,559
(-) Deductions45
Net Taxable Income1,514
(-) Income Tax (15% of $1,514 million)227.10
After-Tax Income1,286.90

Thus, Jonas’s after-tax income for FY 2018-19 is $1,286.90 million, and the tax paid by him for the FY 201-19 is $227.10 million.
