How to calculate meals and entertainment deduction
Imagine your company’s financial statements show a total of $10,000 in combined meals and entertainment expenses for the year. To determine the correct tax deduction, you must first separate these costs and apply the specific tax rules to each category.
Step 1: Isolate nondeductible entertainment expenses
The first step is to identify any costs classified as entertainment. As mentioned earlier, under current tax law, most entertainment expenses are 100% nondeductible.
In our scenario, let’s say that out of the $10,000 total, $2,000 was spent on entertainment. For tax purposes, this entire amount is disallowed.
Step 2: Apply the 50% limitation to business meals
Next, you address the remaining expenses. The balance of the recorded cost is for business meals.
- Total meals & entertainment expense: $10,000
- Entertainment (nondeductible): -$2,000
- Remaining business meals: $8,000
Generally, business meals are subject to a 50% limitation on their deductibility. This means only half of the cost can be deducted on the tax return.
- Business meal expense: $8,000
- 50% Limitation: x 0.50
- Deductible meal amount: $4,000
Step 3: Calculate the total M-1 adjustment
The M-1 adjustment reconciles the difference between the expense recorded on the books and the amount allowed as a tax deduction. It represents the total nondeductible portion of the book expense, which must be added back to your book income to arrive at taxable income.
Here is the calculation based on our example:
- Book Expense: $10,000 (the full amount recorded in your financial statements)
- Tax Deduction: $4,000 (the deductible portion of the meals)
- M-1 Adjustment: $10,000 (Book) – $4,000 (Tax) = $6,000
This $6,000 add-back is entered on Schedule M-1 to account for the nondeductible entertainment expenses ($2,000) and the nondeductible portion of the business meals ($4,000).
