Under a Section 3121(l) agreement, which statement describes a potential reason a U.S. employer might not want to use it?

• A. It allows the employee to continue paying payroll taxes into the host jurisdiction’s system.
• B. It requires the employee to switch payroll taxes to the host jurisdiction.
• C. The employee will work for a separate host jurisdiction employer that has its own social insurance contribution program
• D. It automatically doubles payroll tax obligations

Answer: (C)

This question hinges on what happens under a Section 3121(l) agreement when an employee works outside the U.S. and how payroll and social‑insurance coverage are handled. Such an agreement is used to coordinate or sometimes shift social‑security coverage so that the employee isn’t doubly taxed, typically involving foreign coverage instead of U.S. FICA. A potential drawback is that the arrangement can require the employee to be employed by a host-country employer that has its own social-insurance program. That means the U.S. company may need to deal with a local employer of record or establish a local payroll setup, adding complexity, separate administration, and potentially unfamiliar rules and costs. This added complexity is a real reason a U.S. employer might avoid using the section 3121(l) path. The other options describe scenarios that are more neutral or beneficial aspects of such an arrangement (for example, aligning payroll with the host system to avoid double taxation, or indicating a shift in tax handling that isn’t inherently a downside). And the option about doubling payroll tax obligations runs counter to the purpose of these agreements, which is to prevent double taxation. So, the statement about working for a separate host jurisdiction employer with its own social-insurance program captures a practical, real-world drawback that can deter an employer from pursuing a 3121(l) agreement.
