Keep in mind: Not every deadline applies to every taxpayer. Filing requirements depend on the taxpayer’s registration, tax type, fiscal year, filing system, and other circumstances. Deadlines that fall on a weekend, holiday, or non-working holiday are generally moved to the next working day, in accordance with applicable BIR rules.
Tax deadlines and requirements may change based on updates and issuances from the Bureau of Internal Revenue (BIR). Stay updated with the latest BIR announcements and verify the applicable deadlines for your business before filing or making payments.
