What is business travel?
Business travel is any trip your job sends you on. This cheat sheet covers how to think about it and where company travel programs go wrong. The detail is further down.
How to think about it
- Home means your work area. For tax purposes, your home is generally your regular place of business, and it includes the whole city or general area where you work, wherever your family lives.
- Commuting never counts. The cost of getting between home and your main or regular place of work is a personal commuting expense, no matter how far it is.
- Long assignments change the math. An assignment in one place expected to last more than a year is indefinite, and that location becomes the traveler's new tax home.
- Ordinary and necessary. Travel expenses are the ordinary and necessary costs of traveling away from home for work. Ordinary means common and accepted in your trade, necessary means helpful and appropriate.
Where travel programs go wrong
- Too many booking channels. Booking across different channels leads to inconsistent costs and makes spending policies hard to enforce.
- Approvals with no system. Without a structured system, requests get lost or delayed.
- Rules that frustrate. Too many rules lower employee satisfaction, while too much flexibility drives up costs.
- Manual receipts. Manual processes for receipts and documentation lead to reporting mistakes and compliance issues.
Types of business travel

How it works on Engine
On Engine, travelers and authorized bookers can book hotels, flights (round-trip, one-way and multi-city) and rental cars. Admins set lodging, flight and rental-car rules in travel policies, and Engine applies them during the booking flow.
Questions
What counts as business travel?
Any trip taken for professional reasons outside a person's typical work area, including client visits, training sessions, trade shows and internal meetings across offices. Commutes, vacations and purely leisure trips don't count.
Is commuting business travel?
No. The IRS treats travel between home and your main or regular place of work as personal commuting, even if you work during the trip.
How long can a business trip last before the rules change?
For tax purposes, an assignment in one place realistically expected to last a year or less is temporary. One expected to last more than a year is indefinite, and the traveler can't deduct travel expenses while there.
What is the difference between business travel and bleisure?
Bleisure is travel that blends business and personal time, such as a work trip extended for personal time. Under IRS rules, if the trip was primarily for business, only the business-related travel expenses are deductible, including getting to and from the business destination.
