What travel expenses are tax deductible under Publication 463?

IRS Publication 463 allows deductions for ordinary and necessary travel expenses incurred while away from your tax home on business. Deductible expenses include: airfare, train, and bus tickets; lodging; meals (subject to 50% limit); dry cleaning and laundry; business calls; tips related to these expenses; and transportation costs at the destination (taxis, rental cars). Travel must be overnight or require rest/sleep to meet IRS requirements. Commuting between home and your regular workplace is never deductible.

What is the 50% meal deduction limit?

Under Publication 463, business meal expenses are only 50% deductible. This applies whether you use actual expenses or the standard meal allowance (per diem) method. Meals must not be lavish or extravagant. The meal must be business-related, and you must be present when the food or beverages are provided. For 2024-2025, certain employer-provided meals may qualify for the higher 100% deduction under temporary provisions, but standard business dining remains at 50%.

What is the gift expense limit per IRS rules?

IRS Publication 463 limits business gift deductions to $25 per person per year. Incidental costs (engraving, wrapping, mailing) do not count toward the $25 limit. Gifts to a company's employees are not subject to the $25 limit if the gift is for length of service or safety achievement. The $25 limit applies per recipient — gifts to a client's spouse or children are considered gifts to the client if there is a business connection.

Deductible Travel, Gift & Car Expenses

Business Travel

Airfare, hotels, rental cars, and 50% of meals while traveling overnight for business. Travel must require sleep or rest to qualify as business travel away from your tax home.

Standard Mileage Rate

For 2024, the standard mileage rate is 67 cents per mile for business driving. Alternatively, you may deduct actual vehicle expenses including gas, maintenance, insurance, and depreciation.

Accountable Plans

Employer reimbursements under accountable plans are tax-free. Employee must substantiate expenses and return any excess. Non-accountable plan reimbursements are taxable wages.

Per Diem Rates

Instead of tracking every meal receipt, use the federal per diem meal allowance (varies by location). Record the dates, location, and business purpose — but skip individual meal receipts.

Business Gifts

Limited to $25 per person per year. Incidental wrapping or shipping costs are excluded. Gifts to employees for length of service or safety achievement are not subject to the $25 limit.

Common Mistakes & Non-Deductible Items

Commuting Rule

Commuting between your home and regular workplace is never deductible — no exceptions. This is the single most denied expense in travel audits.

Entertainment Post-TCJA

Entertainment expenses (client tickets, golf outings, sporting events) are generally non-deductible after the Tax Cuts and Jobs Act, even if business is discussed.

Luxury Water Travel

Deductions for travel by cruise ship or other luxury water travel are capped at twice the highest federal per diem rate for the number of days of the trip.

No Substantiation

The IRS disallows deductions wholesale when adequate records are missing. A mileage log, receipt, or calendar entry without business purpose = disallowed.
