How Do I Handle Out-of-Town Travel?
If you must travel overnight to another area for business, your reasonable expenses for travel, lodging and meals (the latter subject to the 50% limitation) are generally deductible.
You cannot deduct the additional costs of having your spouse or family members accompany you on a business trip, unless they are also your employee and their presence has a legitimate business reason other than their being your companion.
For further information, including information about a per-diem meal rate you may be able to use in lieu of your actual expenses for meals and incidental expenses, see IRS Publication 463.
