1. How much is the self employment tax for Illinois?
Employers withhold Social Security and Medicare taxes and make payments on behalf of their employees. But individuals who work for themselves have to pay their own Illinois self employment tax. That amount is 15.3%, with 12.4% going to Social Security and 2.9% going to Medicare.
2. How much do I owe in self employment tax to the government?
To determine the amount of Illinois self employment tax owed, you need to determine your annual earnings. Then you apply the Social Security 12.4% to a base amount, established in 2020 as the first $137,700 of your net earnings. The Medicare 2.9% is applied to all your combined net earnings. If you have a married couples business there are some variations in what you would file.

4. What forms do I need to file taxes?
