If you don't satisfy the IRS's substantiation rules, your deduction can be disallowed. Under the TCJA, beginning in 2018 and beyond, only the cost of meals and beverages are 50% deductible when entertaining for business purposes. For 2017 and prior years, 50% of the cost of meals and beverages, as well as other entertainment costs are deductible, such as tickets to sporting events and the theater.
For 2018 and beyond, when entertaining for business purposes, if you are provided with one bill for the cost of the entertainment, make sure the bill shows the cost of the meals and beverages separately from other costs. This is a requirement to get the meal/beverage deduction.
The key points to remember for 2018 and beyond and 2017 and prior years is this:
Document Entertainment Expenses:
The TCJA does not change IRS substantiation rules. The only difference for 2018 and beyond is that meals and beverages must be separately. Prior to 2018 there was no such requirement.
Since only the cost of meals and beverages are deductible beginning 2018 under the Tax Cuts and Jobs Act (50% of the cost) and non-meal/beverage costs when entertaining are not deductible, your general ledger should segregate the cost of meals and beverages from other entertainment-related costs. Doing this will facilitate tax preparation and financial reporting.
What to do:
For 2018, under the TCJA, you may only deduct the cost of meals and beverages when entertaining customers or clients at your home.
For tax years 2017 and prior, you may meal and beverage cost as well as non-meal/beverage costs when entertaining for business purposes. Make sure you document the business purpose and have all guests sign a guest register.
Keep a record showing:
If non-business guests also attend, only deduct costs associated with business guests. Keep a record that shows the total cost for all guests. For 2018 and beyond, be sure to separately state the cost of meals and beverages.
You should have a guest register for people to sign in. Your guest register should include at least three columns:
If audited, the IRS will see that you accounted for both business and nonbusiness guests separately and did not attempt to deduct costs related to nonbusiness guests.
