Business Travel Deductions for Expats: What You Can Write Off

Expats often travel for work—both internationally and back to the U.S. Understanding which travel expenses are deductible can significantly reduce your tax bill. Here's what you need to know about business travel deductions when living abroad.

The Basics: What's Deductible?

Business travel expenses are deductible if the travel is:

• Ordinary and necessary for your business
• Away from your tax home overnight
• Primarily for business purposes

Deductible Travel Expenses

Expense Type	Deductible?
Airfare	✅ Yes (business portion)
Lodging	✅ Yes
Meals (business)	✅ 50% deductible
Local transportation	✅ Yes (taxi, rideshare, rental car)
Business calls/internet	✅ Yes
Tips	✅ Yes
Dry cleaning	✅ Yes
Personal sightseeing	❌ No

Expat-Specific Considerations

Your Tax Home Is Abroad

As an expat, your tax home is your foreign location. This means travel TO the U.S. can be business travel (not personal), while travel from the U.S. would have been personal before you moved.

U.S. Business Trips

When you travel to the U.S. for business:

• Flight costs are deductible if primarily for business
• Lodging during business days is deductible
• Days visiting family are personal (not deductible)
• You must allocate expenses between business and personal days

💡 Strategy: Structure U.S. trips so business purposes predominate. If over 50% of your days (excluding travel days) are for business, the entire airfare may be deductible.

The "Primarily Business" Test

Domestic U.S. Travel

For travel within the U.S. (including trips from abroad to the U.S.):

• If trip is primarily business: Full transportation deductible
• If trip is primarily personal: No transportation deductible
• Either way: Only business-day expenses (lodging, meals) are deductible

International Travel

For travel between countries (excluding U.S.):

• Same rules apply
• Weekends sandwiched between business days count as business

Self-Employed vs. Employee

Self-Employed

You can deduct business travel expenses directly on Schedule C:

• Reduces your self-employment income
• Reduces both income tax AND self-employment tax
• Must maintain excellent records

W-2 Employees

Since the 2017 Tax Cuts and Jobs Act:

• Unreimbursed employee expenses are NOT deductible (2018-2026)
• You can only benefit if your employer reimburses you
• Employer reimbursements under an accountable plan aren't taxable

The 330-Day Test Interaction

Business travel to the U.S. affects your FEIE qualification:

Days in the U.S. Still Count Against You

• Even business days in the U.S. reduce your foreign day count
• You only get 35 days in the U.S. within your 12-month period
• Plan U.S. business trips carefully

Income Earned in the U.S.

• Work performed in the U.S. is U.S.-source income
• U.S.-source income is NOT excludable under FEIE
• Even if you're an expat, days worked in the U.S. create taxable income

Documentation Requirements

The IRS requires contemporaneous records for travel deductions:

What to Keep

• Receipts: For all expenses over $75 (keep all receipts anyway)
• Travel log: Date, location, business purpose
• Calendar: Showing business activities each day
• Business purpose documentation: Meeting agendas, client emails, contracts

Credit Card Statements Aren't Enough

A credit card statement shows what you spent but not the business purpose. You need both.

Conferences and Conventions

Attending a conference abroad? Special rules apply:

• Must be directly related to your business
• Convention must be reasonably held in that location
• Strict limits on cruise ship conventions (max $2,000)
• No deduction for conventions in most Caribbean countries (unless tax agreement exists)

Combining Business and Personal Travel

Best Practices

1. Schedule business activities first; add personal time around them
2. Keep business and personal expenses clearly separated
3. Document the business purpose thoroughly
4. If extending a trip for vacation, only deduct business-day costs

Spouse Travel

Your spouse's travel expenses are generally NOT deductible unless:

• They are your employee
• They have a bona fide business purpose for the trip
• Their expenses would otherwise be deductible

📌 Bottom Line

Business travel deductions can significantly reduce your tax bill, but they require careful planning and documentation. As an expat, be especially mindful of how U.S. business trips affect both your FEIE qualification and the source of your income. Keep meticulous records, and when in doubt, photograph that receipt.
