For any restaurant, labor is a massive and critical expense, second only to the cost of food and beverages. The total of these two categories—Cost of Goods Sold (COGS) and labor, is known as the prime cost, the most important number for measuring a restaurant's profitability.
While restaurant managers must track labor costs by department (Front-of-House vs. Back-of-House) for internal analysis, the IRS has a simpler, unified category for tax purposes. This guide will clarify how to categorize all your labor costs according to IRS rules to ensure your business remains compliant and your financial reporting is accurate.

However, these are not included in the "Wages" line.
Properly accounting for labor costs means reporting wages and their associated taxes in their correct, separate categories.
