Solo Operating: Payroll Obligations and S-Corp Considerations

As a solo operator, you have simplified payroll compliance -- unless you elect S-corp status, which requires you to run payroll for yourself. Understanding this distinction is critical to avoiding audit risk.

You skip most payroll obligations. Without employees, you do not file Forms 940 (federal unemployment) or 941 (quarterly payroll tax returns). You do not withhold income tax or FICA for anyone else. This eliminates one of the most compliance-heavy areas of business taxation.

The S-corp exception matters. If you operate as an S-corporation or an LLC taxed as an S-corp, the IRS requires you to pay yourself a reasonable salary. That means running payroll for at least one person -- you. Failing to pay yourself reasonable compensation is a top S-corp audit trigger. The IRS looks at the ratio of salary to distributions and compares it to industry norms.

Sole proprietors report differently. If you are a sole proprietor or single-member LLC, your business income flows to Schedule C and you pay self-employment tax on net profit. There is no payroll to run because you are not an employee of your own business.

The pitfall: Choosing "no employees" while operating an S-corp is a red flag. If you elected S-corp status, you must run payroll for yourself -- there is no workaround.
