Liaison Office

A **liaison office**, also called a representative office or rep office, is a presence established by a foreign company in another country for non-commercial purposes only. Permitted activities typically include market research, promoting the parent's products, gathering information, liaising with local agents and customers, and coordinating quality control. The liaison office is **not allowed to enter into contracts, generate revenue, or invoice customers** in the host country.

Because it does not earn income locally, a liaison office is generally not subject to corporate income tax, although it must usually file an annual return showing its expenses and confirming compliance with the activity restrictions. Costs are typically borne by the parent through expense reimbursements.

Common examples are Indian RBI-approved liaison offices, Chinese representative offices regulated by SAMR, and Japanese rep offices for foreign banks. Many jurisdictions impose strict registration and reporting requirements, and some, such as India, require central bank approval and impose strict prohibitions on revenue-generating activities. Crossing the line into commercial activity can trigger reclassification as a branch or a permanent establishment, with retroactive tax exposure.

Companies use liaison offices when they want a low-cost local presence to test a market, build relationships, or oversee local distributors and licensees, without committing to a full branch or subsidiary. Many countries impose a sunset on the liaison structure: India, for example, allows them for up to three years subject to extension. Tax advisors monitor activities carefully because revenue-generating work can convert the office into a taxable permanent establishment, exposing the parent to back taxes and penalties.
