Estimate what an S-corp election could save you
This free S-corp tax savings calculator estimates how much self-employment tax you could save by electing S-corporation status instead of operating as a sole proprietor or default LLC. Electing an S-corp is one of the most common tax-planning moves for profitable freelancers and small-business owners — but it only pays off above a certain profit level, and this tool shows you exactly where that line is.
Enter your net business profit, the reasonable salary you would pay yourself, and the extra cost of running an S-corp. The calculator returns your estimated annual tax savings and the breakeven profit at which an S-corp starts to make financial sense. It's built for sole proprietors and LLC owners wondering whether it's time to make the switch.
How an S-corp saves on tax
A sole proprietor pays 15.3% self-employment tax on essentially all business profit. An S-corp owner instead splits profit into two parts: a reasonable salary, which is subject to payroll tax, and a distribution, which is not subject to self-employment or payroll tax.
The savings is the payroll tax avoided on the distribution portion — minus the cost of running the S-corp. The larger your profit relative to a defensible salary, the larger the potential saving.
The reasonable salary requirement
You cannot pay yourself a $0 salary and take all profit as a distribution. The IRS requires a reasonable salary for the work you actually do, and an unreasonably low wage is a well-known audit trigger. The bigger the legitimate gap between a defensible salary and total profit, the bigger the savings — but the salary has to hold up to scrutiny based on your role, industry, and hours.
The overhead that eats into the savings
An S-corp adds real, recurring costs: running payroll, filing a separate corporate tax return, more bookkeeping, and often state fees or franchise taxes — commonly $1,500 to $3,000 a year. Below a certain profit level that overhead cancels out the tax savings entirely, which is why this calculator also computes your breakeven profit. Many freelancers find an S-corp begins to pay off somewhere around $80,000–$100,000 of net profit, but the exact figure depends on your salary and overhead.
Frequently asked questions
At what income does an S-corp make sense?+
It varies with your reasonable salary and overhead, but many freelancers find an S-corp starts paying off somewhere around $80,000–$100,000 of net profit. The calculator computes your specific breakeven figure.
How does an S-corp reduce self-employment tax?+
An S-corp owner pays payroll tax only on their salary, not on the profit taken as a distribution. The self-employment tax avoided on that distribution is the savings — offset by the cost of running the S-corp.
Does TaxClover handle S-corp taxes?+
No — TaxClover is built for sole proprietors and single-member LLCs filing a Schedule C. S-corp payroll and returns are out of scope. This calculator is here to tell you when it's worth talking to a CPA about electing one.
Is this calculator a complete S-corp analysis?+
No. It estimates payroll-tax savings only. It doesn't model the QBI deduction interaction, state-level taxes and fees, or retirement-plan effects. Use it as a directional check, then get a full analysis from a tax professional.
