How would you like Uncle Sam to pay for part of your vacation? Sound unlikely? If you combine your vacation with a business trip, you may be able to deduct some of your expenses. Pay attention to the rules, though. Expenses must meet certain requirements before they’re tax deductible.
General Guidelines
As long as your primary reason for making the trip is business, you generally can deduct the cost of your transportation to and from your destination. You’ll generally be able to deduct food (within limits) and lodging costs only for the days you actually spend on business.
Bring the Family
You can bring your family along, too. While you can’t deduct their food, lodging, or airfare, you can write off your own expenses, including the single-occupancy rate for lodging on days when you’re conducting business. If you and your family travel by car, you can also deduct the full cost of transportation. Just be sure to keep detailed records.
