Quick Answer
An S-Corp tax calculator estimates how much you can save in self-employment tax by electing S-Corporation status. As a sole proprietor, you pay 15.3% self-employment tax on all net business income. As an S-Corp, you only pay employment taxes on your reasonable salary — distributions above that amount are exempt from the 15.3% tax. For a business earning $200K net, the typical savings range from $12K to $20K per year depending on the reasonable salary level. Before you pick a salary number, make sure you understand the reasonable salary rules — setting it too low is the #1 S-Corp audit trigger.
Worked Example: Consultant — $200K Net Income
Without S-Corp: $200K × 15.3% = $30,600 SE tax (technically calculated on 92.35% of net = $28,263)
With S-Corp at $90K salary: Employment tax on $90K = $90K × 15.3% = $13,770
Savings: $28,263 - $13,770 = $14,493/year in SE tax saved
Minus ~$3,000 S-Corp compliance costs = net savings ~$11,500/year

When Does an S-Corp Make Sense?
The S-Corp election is a powerful tax strategy, but it's not free. It trades self-employment tax (15.3%) for payroll costs and compliance complexity. To make it worth it, your tax savings must outweigh the costs of running payroll, filing a separate tax return, and paying state franchise taxes. Not sure where to start?
