Reasonable Salary Frequently Asked Questions
A reasonable salary is the compensation an independent business would pay for the same services under similar circumstances. The IRS evaluates duties performed, volume of business, hours worked, and industry salary standards.
If an active shareholder-employee pays themselves $0 salary and takes only distributions, the IRS can audit the corporation and reclassify 100% of the distributions as wages, assessing back payroll taxes, penalties, and interest.
IRS Reasonable Compensation Guidelines & Audit Rules
1. The "60/40 Rule" Myth
Many accountants use a rule of thumb taking 60% as salary and 40% as distributions. However, the IRS does not officially endorse a flat percentage. IRS Fact Sheet 2008-25 specifies that reasonable compensation must reflect actual market value of services provided.
2. Factors Considered by IRS Examiners
IRS auditors review: (1) training and experience, (2) duties and responsibilities, (3) time and effort devoted to the business, (4) dividend history, (5) payments to non-shareholder employees, and (6) comparable wages in similar firms.
3. The Three-Factor Approach
Tax courts frequently apply the Three-Factor approach: separating compensation into (a) compensation for shareholder services, (b) return on company capital investment, and (c) entrepreneurial profit.
4. Penalties for Underpaying Salary
If audited and found non-compliant, the IRS will reclassify dividend distributions as wages, assessing back 15.3% FICA payroll taxes, substantial failure-to-deposit penalties, and interest charges.
