S-Corporations are a popular business structure in the U.S., offering certain tax benefits to small businesses. You may have heard that the structure allows for employment tax savings. But how do you calculate the S-Corp self-employment tax?
As a pass-through entity, S-Corporations do not pay federal income tax on their profits. Instead, the profits are allocated to the shareholders, who report them on their personal tax returns.
This tax structure can provide significant tax savings for the shareholders, but it also has specific rules and regulations that must be followed. One of the most essential rules that S-Corporations must abide by is the requirement to pay their officers a reasonable wage.
What is an S corporation?
It is basically the bread-and-butter entity for small businesses. The reason why it is so loved is it saves on self-employment taxes. The owner only has to pay employment taxes on a W-2 that the company issues. All remaining profits flow through enter text of the individual level.
The entity structure has become very popular in recent years. You must file for 2553 to elect to be taxed as an S Corp.

You also have the option to revoke the election if desired. But remember to pay yourself a wage subject to employment taxes. Your W-2 must be based on reasonable compensation. IRS requirements drive this.
How does Self-Employment Tax Work?
First of all, we need to get one issue squared away. S corporation owners do not pay self-employment tax themselves. Self-employment taxes are assessed against the profits of a sole proprietor or schedule C filer.
But an S corporation works a little differently. The profits of the S corporation are not subject to self-employment tax. So the only way employment taxes are assessed is through issuing a W-2 wage to the business owner and company officers.
Said differently, employment taxes do not drive the final net income on form 1120-S. You must calculate the wage to assess them.
You may begin thinking that this is great news. You can save the entire amount of employment taxes.
Not so fast. The IRS has issued reasonable compensation rules that ensure owners pay appropriate self-employment taxes. However, if you structure the wages correctly, you still can have some self-employment tax savings.
Reasonable Compensation Rules
The IRS requires that S-Corporation officers receive “reasonable compensation” for the services they provide to the company. This rule is in place to prevent S-Corporations from avoiding payroll taxes by paying officers low salaries and distributing the remaining profits as dividends. Determining what constitutes reasonable compensation can be complex, and there is no one-size-fits-all approach.

S-Corporations must consider several factors when determining reasonable compensation, including the officer’s qualifications, experience, responsibilities, and the prevailing market rates for similar positions. This article will explore the rules and guidelines for determining a reasonable wage for S-Corporation officers and the potential consequences of failing to comply.
Calculating S Corp Self-Employment Tax
To calculate self-employment tax for S corp owners, you must first determine the owner’s net self-employment income. This is calculated by subtracting any allowable deductions from the owner’s gross income.
S-Corp | C-Corp | Partnership | Sole Proprietor |
---|---|---|---|
Pass-Through Taxation | Double Taxation | No Officer W2 | Included on 1040 |
Form 1120-S | Form 1120 | Pass-Through Taxation | Schedule C |
Reasonable Compensation Rules | Officer W2 | Form 1065 | Easy to File |
Form 2553 Election | Dividend Tax | Issues K-1 | Subject to Employment Tax |
Once you have determined the owner’s net self-employment income, you can calculate the self-employment tax. The self-employment tax rate for 2021 is 15.3%, which includes 12.4% for Social Security and 2.9% for Medicare.
However, S corp owners may only need to pay self-employment tax on a portion of their income. If the owner receives a distribution from the S corp, that income is not subject to self-employment tax. Additionally, the owner may be able to deduct certain business expenses, which can reduce their taxable income.
Working with a CPA is important to ensure you accurately calculate your self-employment tax and take advantage of any available deductions.
How do you Determine a Reasonable Wage for S Corp officers?
Determining a reasonable wage for S-Corp officers involves carefully analyzing various factors, including the officer’s qualifications, experience, responsibilities, industry norms, and comparable salaries for similar positions. Here are some steps that can be taken to determine a reasonable wage for S-Corp officers:
- Evaluate the officer’s qualifications: Consider the officer’s education, training, skills, and experience. Officers with more education, training, and experience in their field may command higher salaries than less qualified officers.
- Assess the officer’s responsibilities: Consider the officer’s duties, level of authority, and overall contribution to the company. An officer with more significant responsibilities or who oversees more employees or departments may warrant a higher salary.
- Look at industry standards: Research what other companies in the same industry pay for similar positions. This can be done through salary surveys or job postings.
- Consider the company’s financial situation: The company’s financial health and profitability should be considered when setting officer salaries. The company should be able to afford the salary, and the compensation should be competitive enough to attract and retain qualified officers.
- Consult with professionals: Companies can consult with tax professionals, attorneys, or other experts who have experience determining reasonable compensation for S-Corp officers.
Once a reasonable wage has been determined, it’s essential to document the compensation decision process. This can help demonstrate to the IRS that the compensation is reasonable if there are any questions or audits in the future.
Final thoughts
In summary, S-Corporations must pay their officers a reasonable wage that reflects the services provided to the company. By carefully considering all relevant factors and consulting with professionals as needed, S-Corporations can set officer salaries that comply with IRS rules and regulations. In doing so, they can avoid costly penalties and fines while ensuring that their officers are fairly compensated for their contributions to the company’s success.
