Salary Tax Calculations for a Illinois Resident Earning $30,000.00

Print version


While the United States has its own set of "general tax rules" that all states must follow, the tax rates that each state have in place differ. This is due to how state taxes and regulations vary depending on where you live. For the calculation, we will be basing all of our steps on the idea that the individual filing their taxes has a salary of $30,000.00. If you earn $30,000.00 (or earn close to it) and live in Illinois, then this will give you a rough idea of how much you will be paying in taxes on an annual basis. However, an annual, monthly, weekly, and daily breakdown of your tax amounts will be provided in the written breakdown.

The taxes that are taken into account in the calculation consist of your Federal Tax, Illinois State Tax, Social Security, and Medicare costs that you will be paying when earning $30,000.00.

Our Illinois State Tax Calculator will display a detailed graphical breakdown of the percentage, and amounts, which will be taken from your $30,000.00 and go towards tax. While this calculator can be used for Illinois tax calculations, by using the drop-down menu provided you are able to change it to a different State. You can choose another state for federal and state tax calculation here.

The Breakdown

As we said above, the calculator will provide you with a detailed breakdown of your tax payments. These payments will be split into 4 categories. Federal Taxes, FICA Taxes (Social Security and Medicare), and your State Taxes. However, it is important to remember that when you file your taxes as an individual (otherwise known as "Single Filing"), the amount you pay is different than if you were to file with your partner (otherwise known as "Marriage Filing"). So, in this example, we will breakdown your taxes if you were to file $30,000.00 as "Single".

Single Filing

You start with $30,000.00 as your annual salary. After entering it into the calculator, it will perform the following calculations.

  • - Federal Tax.  Filing $30,000.00 of earnings will result in $ of that amount being taxed as federal tax.
  • - FICA (Social Security and Medicare).  Filing $30,000.00 of earnings will result in $ being taxed for FICA purposes.
  • - Illinois State Tax.  Filing $30,000.00 of earnings will result in $ of your earnings being taxed as state tax (calculation based on 2024 Illinois State Tax Tables).

This results in roughly $ of your earnings being taxed in total, although depending on your situation there may be some other smaller taxes added on.

Although this is the case, keep in mind that there are deductions in place and you may be subject to additional deductions, lowering the amount you will be paying in taxes. Taxes are delicate, which is why it is important for you to use the right tools to calculate how much you owe the government in taxes. Use our Illinois State Tax Calculator to be given an accurate breakdown of your tax payments for the current tax year.
