For November year-ends (return due about 1 May of the following year, with no extension), target audit completion by mid-April. For December year-ends (return due mid-August of the following year), target completion by end of July. Plan to engage the auditor at least 3 months before the BIR52 deadline.

All Hong Kong private limited companies must have their accounts audited by a CPA (Practicing) registered in Hong Kong, regardless of company size or revenue. Audit must be completed before the Profits Tax Return (BIR52) can be filed.
