Summer is a popular time for business owners and professionals to combine work obligations with personal travel. Whether you’re attending a conference in a sunny locale, meeting clients in a vacation hotspot, or tacking on a few days of relaxation to a business trip, understanding the tax rules for “mixing business with pleasure” can help you maximize deductions and avoid costly mistakes. Here’s what you need to know for 2025.
1. The Basics: When Are Travel Expenses Deductible?
The IRS allows deductions for “ordinary and necessary” expenses incurred while traveling away from home for business purposes (IRC §162(a)(2)).
To qualify:
You must be away from your tax home (your regular place of business) substantially longer than an ordinary day’s work, and
You must need to sleep or rest to meet the demands of your work while away [1].
Key Point: The primary purpose of the trip must be business. If the trip is primarily for personal reasons, travel costs to and from the destination are not deductible, though business expenses incurred at the destination may be [1].
2. Allocating Expenses: Business vs. Personal Days
When a trip includes both business and personal activities, you must allocate your expenses:
Transportation (e.g., airfare): If the trip is primarily for business, the full cost of getting to and from the destination is deductible, even if you add some personal days. If the trip is primarily for pleasure, transportation is not deductible [1].
Lodging, meals, and incidentals: Only expenses incurred on business days are deductible. Personal days (vacation, sightseeing, etc.) are not [1].
How to Count Business Days:
Days spent traveling to and from the business destination (if by a direct route) are business days.
Days when your presence is required for business (meetings, conferences, etc.) are business days.
Weekends and holidays between business days count as business days.
Days spent primarily on personal activities are not business days [1].
Example: You fly to Miami for a three-day business conference (Wednesday–Friday), then stay through Sunday for personal relaxation. Your round-trip airfare and hotel for Wednesday–Friday is deductible. Hotel and meals for Saturday and Sunday are not.
3. International Travel: Stricter Allocation Rules
For trips outside the United States, the IRS imposes stricter allocation rules if the trip is more than a week and more than 25% of the time is spent on nonbusiness activities. In such cases, you must prorate your travel expenses between business and personal days [1].
Exceptions: If you have no substantial control over the trip’s arrangements (e.g., you’re sent by your employer), or if the trip is less than a week, or less than 25% of the time is personal, you may deduct the full cost of transportation [1].
4. Bringing Family or Friends
Generally, you cannot deduct the travel expenses of a spouse, dependent, or friend unless:
They are an employee,
Their presence serves a bona fide business purpose, and
The expenses would otherwise be deductible by them [1].
If your spouse or child joins you for personal reasons, their incremental costs (e.g., extra hotel room charges) are not deductible [1].
5. Mixing Business with Pleasure: Practical Strategies
A. Schedule Business Activities at the Start or End of Your Trip
If you schedule business meetings at the beginning and end of your trip, weekends and holidays in between can be counted as business days, making more of your travel deductible [1].
B. Keep Meticulous Records
Document the business purpose of your trip, keep receipts, and maintain a log of business and personal days. The IRS requires substantiation of the time, place, amount, and business purpose for each expense [1].
C. Use Per Diem Rates for Meals and Incidentals
Instead of actual expenses, you may use federal per diem rates for meals and incidentals. For 2025, the standard per diem for meals and incidentals is $68 per day for most locations, with higher rates for high-cost areas [2].
D. Deductible Transportation at the Destination
Local transportation (taxis, rideshares, rental cars) for business purposes at your destination is deductible. If you use a rental car for both business and personal purposes, allocate the expense based on mileage or days used for each [1].
6. Special Considerations for Corporate Jets and Private Planes
If you use a company aircraft, the IRS scrutinizes whether flights are for business or personal reasons. Only business-related flights are deductible by the employer. Personal flights must be treated as compensation to the employee, and special valuation rules apply (e.g., Standard Industry Fare Level or SIFL rates) [3].
7. Entertainment and Meals: The 50% Rule
Most business meals are only 50% deductible. Entertainment expenses (e.g., tickets to shows or sporting events) are generally not deductible, even if business is discussed, unless they are separately stated from meals and meet strict substantiation requirements [1].
8. Common Pitfalls to Avoid
Commuting Costs: Travel between your home and regular place of business is never deductible [1].
Insufficient Documentation: Failure to keep adequate records can result in disallowed deductions.
Overstating Business Purpose: The IRS may disallow deductions if the business purpose is not clearly substantiated or if the trip is primarily personal [1].

10. Final Tips
Plan your itinerary to maximize business days.
Document everything: Keep a travel log, receipts, and a calendar of business activities.
Consult a tax professional if you have complex travel arrangements or use company aircraft.
By understanding and applying these rules, you can enjoy your summer travels while ensuring you take full advantage of available business travel deductions—without running afoul of the IRS.
