A simplified personal income tax law cut the number of brackets from seven to five and raised the standard deduction, while a separate resolution abolished the annual business license fee outright. Neither change touches what a representative office can legally do — it still cannot invoice, sign sales contracts, or generate revenue in Vietnam — but both change what it costs to run one. This guide walks a CEO, founder, or GM through what an FDI rep office Vietnam entity is, how it compares with a branch or a subsidiary, what changed in the 2026 rulebook, how staffing and payroll work, and what the annual compliance calendar looks like once the office is open. It closes with what to check before choosing a registered address, since that decision follows the company for the full five-year license term.
