Payroll Taxes for Owners/Employees

There are special considerations if you’re a business owner who also works in the business, depending on its structure:

Partnerships and limited liability companies. Generally, all trade or business income that flows through to you for income tax purposes is subject to self-employment taxes — even if the income isn’t actually distributed to you. But such income may not be subject to self-employment taxes if you’re a limited partner or an LLC member whose ownership is equivalent to a limited partnership interest. Whether the additional 0.9% Medicare tax on earned income or the 3.8% net investment income tax will apply also is complex to determine. So, check with your tax advisor.

S corporations. Only income you receive as salary is subject to payroll taxes and, if applicable, the 0.9% Medicare tax. To reduce these taxes, you may want to keep your salary relatively — but not unreasonably — low and increase the income that is taxed to you through your Schedule K-1 by virtue of your share of the earnings from the business. That income isn’t subject to the corporate level tax or the 0.9% Medicare tax and, typically, is not subject to the 3.8% net investment income tax.

C corporations. Only income you receive as salary is subject to payroll taxes and, if applicable, the 0.9% Medicare tax. Nonetheless, you may prefer to take more income as salary (which is deductible at the corporate level) as opposed to dividends (which aren’t deductible at the corporate level yet are still taxed at the shareholder level and could be subject to the 3.8% net investment income tax) if the overall tax paid by both the corporation and you would be less.
