Business Trip vs. Assignment: Understanding the key differences
Determine if your employee is going on a business trip or assignment, understand the key differences and implications for your travel compliance policy.

Companies with international operations are routinely sending employees across borders for various purposes. Distinguishing between a business trip and an assignment for these travels is crucial, as it impacts both the employee experience and compliance requirements for the employer. However, making this distinction isn't always straightforward - and incorrect classification might have significant consequences.
Let's explore the key differences between these two types of cross-border work and how WorkFlex can help you navigate them effectively.
What defines a business trip?
A business trip typically involves:
- Short-term, task-oriented travel: Employees travel to accomplish specific, limited objectives
- Occasional presence: The employee maintains their primary workplace in their home country
- Limited local integration: The employee isn't working "like a local" but rather as a visitor
Example: A CEO flying to a new potential market to meet local officials, sign agreements, set up office is a clear business trip. Similarly, an HR professional traveling to implement a specific process in the foreign subsidiary would typically be classified as a business trip.
What constitutes an assignment?
An assignment generally features:
- Longer duration: Often lasting several months up to years (though duration alone isn't the determining factor)
- Deeper integration: The employee works "more like a local" during their stay
- Changed living arrangements: Instead of hotels, employees typically have apartments or other longer-term accommodations
- Extended presence: The employee is embedded in the destination location for a substantial period
- Return-focused: The explicit understanding is that the employee will return to their home location after completing their task
Example: When a company sends a regional director to another country for a year to broaden their professional horizons and strengthen leadership in that region, that's clearly an assignment. Similarly, technical specialists who relocate to bring production facilities up to company standards would typically be on assignment rather than a business trip.
Tax implications: The key differentiator
The most significant distinction between business trips and assignments relates to tax implications:
- Business trips: Companies typically aim to avoid triggering tax obligations in the destination country.
- Assignments: Companies acknowledge and plan for the employee becoming taxable in the destination country.
Generally speaking:
- Under 183 days: Companies may attempt to avoid tax implications (though other compliance requirements like social security certificates still apply)
- Over 183 days: Tax implications in the destination country are virtually inevitable
This distinction is crucial because it determines how you approach compliance planning. With a business trip, the focus is on preserving home country status. With an assignment, the focus shifts to properly managing the necessary compliance steps in the destination country.
Why correct classification matters for your company
Your choice to classify cross-border work as either a business trip or an assignment impacts:
- Compliance strategy: Different compliance actions are required depending on classification
- Cost structure: Business trips often fall under travel policies with different allowances than assignments (e.g., business class flights, stay in a hotel, etc.)
- Benefits and Compensation: Whether a trip is marked as a business trip or an assignment affects what employees expect in terms of accommodations, allowances, and support
Incorrect trip classification can lead to:
- Unexpected tax liabilities
- Compliance penalties
- Excessive costs due to inappropriate policy application
- Employee dissatisfaction due to unmet expectations

Making the right decision for your company
When deciding whether to classify cross-border work as a business trip or assignment, consider:
- Duration: While not the only factor, longer stays typically lean toward assignment classification
- Nature of work: Is the employee visiting temporarily or integrating into local operations?
- Cost implications: Which classification aligns with your budget expectations?
- Compliance comfort level: Are you prepared to manage the compliance requirements of either approach?
