If production is scheduled to start in a certain month, what is the latest time to submit the BOI application?
If the project intends to align BOI certificate issuance, machinery‑duty‑exemption preparation and import arrangements prior to planned production launch, Zhongxin Tax & Accounting generally recommends submitting the BOI application at least 9‑10 months ahead of the target production‑start date, with an additional 1‑month buffer reserved for document preparation. This timeline is not a statutory BOI approval period; it represents project‑management advice aggregating approval reviews, supplementary‑document rounds, promotion‑acceptance formalities, certificate collection, machinery‑list preparation and physical import workflows.
