Business travel means traveling away from your tax home, your regular place of business, long enough to need sleep or rest, for a business purpose. On a qualifying trip, the transportation to get there and around, flights, trains, rental cars, taxis and ride-hailing, plus lodging, baggage fees, and tips, are fully deductible.
Meals while traveling for business are deductible at 50 percent, the same as other business meals. Keep the itemized receipts and note the business purpose of the trip.
When a trip mixes business and personal time, the test is whether it is primarily for business. If it is, your transportation to and from the destination is still deductible, but you can only deduct lodging and costs for the business days, not the personal ones. A trip that is primarily a vacation with a little business mixed in does not qualify as business travel.
Travel to attend a qualifying conference or training in your field counts, and you can combine it with the education rules. Keep an itinerary or a short record of the business activities so the trip's purpose is documented.
