In Hong Kong, the Inland Revenue Department (IRD) issues Individual Tax Returns (BIR60) every May. Taxpayers are required to complete and send the tax return back to the IRD within 1 month of its issuance date. Taxpayers who file electronically via eTAX are automatically granted 1 month extension. For sole proprietors of unincorporated businesses, the deadline can be extended. For instance, tax form 2025 are issued on May 2, the deadline for this group would be August 2, 2025. Nonetheless, it is not uncommon for taxpayers to miss these deadlines due to oversight or misunderstanding of their obligations.
