For any restaurant, bar, or café, the cost of beverages—whether alcoholic or non-alcoholic—is a primary driver of revenue and a major operational expense. To accurately measure profitability, it is essential to track the costs of liquor, beer, wine, and soft drinks separately, as each category has a different margin.
For tax purposes, a common and critical accounting error is to treat these purchases like general supplies. Instead, all beverage costs must be accounted for as Cost of Goods Sold (COGS). This guide will break down how to correctly categorize your beverage purchases as COGS, the importance of inventory management, and how to stay compliant with IRS rules.
The costs of all beverage items you purchase to resell to customers are not a standard expense category. Instead, they are a fundamental component of your Cost of Goods Sold (COGS).
IRS Publication 334 explains that if the purchase or sale of merchandise is an income-producing factor in your business, you must use inventory and calculate your Cost of Goods Sold. COGS is a calculation, not a single line item, that is subtracted from your gross receipts to determine your gross profit.
To correctly calculate your COGS and effectively manage your business, you must accurately track your beverage inventory and separate your costs by category.
The IRS requires you to use a specific formula to calculate your COGS for the year:
(Inventory at the beginning of the year) + (Cost of Purchases) - (Inventory at the end of the year) = Cost of Goods Sold.
Because the sale of beverages is a primary income-producing factor, you are required to use inventory to reflect your income. This means physically counting and valuing your beverage stock at the beginning and end of each tax year.
While the IRS only requires a single purchase figure for your tax return, for successful business management, it is essential to track your beverage costs in separate categories in your accounting system. This allows you to:
Your gross profit is calculated by subtracting your total COGS from your gross receipts. Therefore, accurate tracking of beverage costs is essential for correct tax reporting.
For a sole proprietor filing a Schedule C (Form 1040), the Cost of Goods Sold is calculated in Part III of the form. The total cost of all beverage and food purchases is included on Line 36, purchases, and your inventory values are reported on Line 35 and Line 41.
You must have documentary evidence to substantiate all your beverage costs. Your records should include:
