How to Calculate Bonus Tax?

There are two ways to calculate bonus tax. Let’s explore them one by one in detail.

1. Annualization Method

The annualization method is used to calculate a bonus when it is part of your income. For example, some companies reward the same bonus amount each month adding it to the salary of employees. The state tax department considers this amount as a part of income and asks a person to pay a certain percentage of the annual income tax in which bonus tax is included.

Example: Subject A monthly salary is R34,000 and his bonus is R21,000.

Formula for Annualization

Annualized income: (Bonus x 12) + Annual Salary

(R21,000 x 12) + R40,8000 = R292,800

Annualized income: R292,800

A person who earns R292,800 has to pay 26% tax according to the state tax department.

R292,800 x 26% = R76,128

Formula

Tax on bonus: Tax amount x (Bonus / Annualized income)

R76,128 x (R21,000/ 292,800) = R5,460

Formula

Bonus after tax: Bonus – Tax on bonus

R21,000 – R5460 = R15,540

The bonus after tax is R15,540.

2. Aggregation Method

The above method is for those who receive bonuses with salaries. But, if a person does not receive a bonus every month, he needs to take an aggregation approach to calculate the bonus tax. Here is a simple way to calculate bonus after tax.

Example: Subject B works in a company where he received a bonus due to achieving a great milestone. His salary is R56,000 and he receives R7,000.

Formula

Total monthly income: Salary amount + bonus

R63,000 = R56,000 + R7,000

According to the tax department of South Africa, a person whose salary is R63,000 must pay 31%.

Formula

Tax amount: Total income x 26%

R16,380 = R63,000 x 26%

Formula

Tax on bonus: Tax amount – Tax on salary

R1,490 = R16,380 – R14,890

Formula

Bonus after tax: Bonus – Tax on bonus

R5,590 = R7,000 – R1,490

The bonus after tax is R5,590
