• Figure out the exemptions: Which deductions are you eligible for? It is best to discuss this with your employer or a tax accountant.

• Calculate the tax at the fixed rate: Find out the rate applicable during the fiscal year. For example, as of 2021, the payroll tax rate for social security is 12.4% (6.2% each for the employer and the employee). For Medicare, the present rate is 2.9% (1.45% each).

• If you are self-employed: The income tax you pay depends on the legal structure of the business. It could be a partnership, a limited liability company (LLC), a solo enterprise, etc. To calculate your tax, estimate your yearly income by basing it on your quarterly earnings. Similarly, you can calculate your annual expenses while factoring in any variations depending on the quarter. Now, you can arrive at your taxable income. Remember to use any tax credits for which you might be eligible. You will pay income tax on this taxable income based on the tax rate.

It is considered a good idea to calculate the tax in each quarter to minimize the risk of making a huge payment at the end of the fiscal year. Understanding the differences between payroll- and income taxes is imperative for individuals and business owners alike to keep on top of their finances.
