To help illustrate these benefits further, take a look at this table:

Type of Business Annual Profit/Loss Tax Liability (Assuming 28% Rate)
Sole Proprietorship $100,000 Profit $28,000
Partnership $100,000 Profit $28,000
C Corporation $100,000 Profit $35,000 (Corporate tax) + $20,720 (Individual income tax) = $55,720
S Corporation (Assuming Single Shareholder) $100k profit $22,400

As shown in the table above, choosing to register as an S Corporation can save you thousands of dollars in taxes each year compared to other business structures.

By electing for S Corporation status for tax purposes when registering your Illinois-based company as an S Corp in 2024,you can enjoy numerous financial advantages such as reduced tax liabilities and avoiding double taxation. These savings could be used towards investing back into your business or taking home more income personally.
