How Are S-Corps Taxed?

S-corporations, like partnerships, are pass-through entities. That is, there is no federal income tax levied at the corporate level. Instead, an S-corporation’s profit is allocated to its shareholder(s) and taxed at the shareholder level.

Tax Forms for S-Corporations

Form 1120S is the form used for an S-corporation’s annual tax return. (This makes sense, given that Form 1120 is used for a regular corporation’s annual return.) As with a partnership, Schedules K and K-1 are used to show how the business’s different types of income and deductions are allocated among the owners.

No Self-Employment Tax!

The big benefit of S-corp taxation is that S-corporation shareholders do not have to pay self-employment tax on their share of the business’s profits.

The big catch is that before there can be any profits, each owner who also works as an employee must be paid a “reasonable” amount of compensation (e.g., salary). This salary will of course be subject to Social Security and Medicare taxes to be paid half by the employee and half by the corporation. As such, the savings from paying no self-employment tax on the profits only kick in once the S-corp is earning enough that there are still profits to be paid out after paying the mandatory “reasonable compensation.”

EXAMPLE: Larissa is the sole owner of her S-corporation, an advertising agency. Her revenues from the business are $50,000 per year, and her annual expenses (not counting salary) total $10,000. As such, her S-corp’s profit for the year (before subtracting her own salary) is $40,000.

Larissa’s plan is to pay herself $30,000 in salary, and count the remaining $10,000 as profit, thus saving money as a result of not having to pay self-employment tax on the $10,000 profit.

Unfortunately, Larissa learns that the average advertising professional in her area earns in the $70,000 range annually. As such, she’s going to have a difficult time making the case that $30,000 is a reasonable level of compensation.

In the end, Larissa ends up setting her salary at $40,000 in order to avoid trouble with the IRS. Sadly, her S-corp’s profit (after paying her salary) ends up being $0, so she isn’t really saving any money on taxes as a result of S-corp taxation.

Determining a Reasonable Salary

So what’s a reasonable salary? This exact question is frequently the topic of debate in court cases between the IRS and business owners who are, allegedly, paying themselves an unreasonably small salary in order to save on self-employment taxes.

What makes the situation tricky is that the tax code itself does not provide any specific guidelines for what’s reasonable. That said, the following factors are frequently considered by courts when ruling on the issue:

  • The duties and responsibilities of the shareholder-employee,
  • The training and experience of the shareholder-employee,
  • The amount of time and effort devoted to the business,
  • The wages of the business’s non-shareholder employees, and
  • What comparable businesses pay for similar services.

One way to get a ballpark figure for reasonable salary is to visit salary.com. There you can run a search for the average salary earned by people in your profession in your geographical area.

In Summary

  • S-corporations are pass-through entities. That is, the corporation itself is not subject to federal income tax. Instead, the shareholders are taxed upon their allocated share of the income.
  • Form 1120S is the form used for an S-corp’s annual tax return.
  • Shareholders do not have to pay self-employment tax on their share of an S-corp’s profits. However, before profits are calculated, any owners that work as employees for the S-corp will need to receive a “reasonable” amount of compensation.
