International Project Travel Expenses for Architects
A practical, data-backed guide to controlling costs and automating expense workflows.
To effectively manage your architecture expense management for under $10/user (2026), it's essential to familiarize yourself with these regulations.

Allocation of Business and Personal Time on International Trips
When allocating business and personal time on international trips, it's essential to keep accurate records to ensure compliance and maximize tax benefits. For example, let's say an architect travels to a conference in Tokyo, staying for 10 days and spending 7 days on business activities, such as attending the conference and meeting with clients, and 3 days on personal activities, such as sightseeing.
If you use actual expenses, you can deduct the cost of fuel, maintenance, and other expenses related to business travel.
Keep track of your business and personal activities by keeping a daily log or calendar. This will help you determine the business percentage of your trip and ensure that you're deducting only eligible expenses.
- Keep a daily log or calendar to track business and personal activities.
- Deduct lodging and meal expenses only for business days.
Applicable Rates and Limits for International Travel Expenses
When it comes to deducting international travel expenses, understanding applicable rates and limits is crucial.
Here are some key things to keep in mind:
- For international travel, the M&IE rate applies to meal and incidental expenses, but not to lodging costs.
- Lodging costs can be deducted as a separate expense, and the rates vary by location.
When tracking your expenses, be sure to keep accurate records of your meal and incidental expenses, lodging costs, and transportation costs.
Maximizing Tax Benefits for Small Architecture Businesses
To maximize tax benefits, small architecture businesses should consider the foreign earned income exclusion (FEIE) and how it applies to international project travel expenses.
Qualifying U.S. citizens and resident aliens can exclude up to $132,900 of foreign earned income from U.S. However, specific state tax laws may add further requirements or considerations, so it's essential to consult with a tax professional to ensure compliance with both federal and state tax laws.
To take full advantage of tax benefits, keep accurate records of all business expenses, including receipts, invoices, and bank statements.
