Quick Answer
Philippine small businesses are taxed by structure. Sole proprietors pay the TRAIN graduated rates (0% up to ₱250,000, then 15% to 35%) or an optional 8% flat rate; small corporations pay 25% — or 20% if net income is ₱5M or less and assets ₱100M or less. VAT (Form 2550Q) applies once annual gross receipts exceed ₱3,000,000; otherwise pay 3% percentage tax.

Tax Obligations
Annual Income Tax Return (Sole Proprietorship)
Sole proprietors report all business income and expenses on BIR Form 1701 (or 1701A if using the 8% flat rate or optional standard deduction), with taxable income taxed under the TRAIN graduated rates (0% up to ₱250,000, then 15% to 35%) or at the optional 8% flat rate on gross receipts. Filed annually by April 15 of the following year. The graduated-rate option supports business deductions for rent, utilities, supplies, salaries, and other ordinary business expenses.
Annual Corporate Income Tax Return
Corporations file BIR Form 1702-RT (regular), 1702-MX (mixed/special rate), or 1702-EX (exempt) reporting net taxable income taxed at the 25% standard CREATE rate, or the preferential 20% rate if net taxable income is ₱5 million or less AND total assets are ₱100 million or less (excluding land). The 8% flat rate is available only to individuals, not corporations. Due by April 15 of the following year.
Quarterly Value-Added Tax (VAT) Return
Businesses with annual gross receipts exceeding ₱3,000,000 must register for VAT and file Form 2550Q quarterly. Reports 12% VAT collected on sales, input VAT on purchases, and net VAT payable. Filed by the 25th day after the close of each taxable quarter; monthly VAT declarations (Form 2550M) were discontinued effective 2023. Requires supporting sales and purchase invoices.
Quarterly Estimated Income Tax Payment
If expected annual income tax liability exceeds ₱10,000, quarterly estimated payments are required using Form 1702-Q. Payments are due on April 15, June 15, September 15, and December 15. Amounts paid are credited against the annual income tax liability when the annual return is filed.
Withholding Tax Remittance
Businesses acting as withholding agents withhold income tax from employee salaries and Expanded Withholding Tax (EWT) from payments to contractors and service providers, then REMIT it to the BIR. Compensation withholding is remitted monthly on Form 1601-C; expanded/creditable withholding is remitted on Form 0619-E (monthly) and Form 1601-EQ (quarterly). Forms 2306 and 2307 are not remittance returns — they are the certificates of tax withheld that the business issues to the payee (2306 for final tax, 2307 for creditable/expanded tax) so the payee can claim the credit.
Registration Process
Obtain Tax Identification Number (TIN) from BIR
Visit the BIR Revenue District Office (RDO) serving your business location within 30 days of commencing operations. Bring a valid government-issued ID, proof of business address (utility bill or lease agreement), and a completed BIR Form 1901-A (Application for Registration). The BIR will issue a Certificate of Registration (COR) and assign a TIN, which is required for all tax filings and business transactions.
Register with the Social Security System (SSS)
If your business will have employees, register with the SSS within 30 days of hiring. Visit the nearest SSS branch with your COR, TIN, proof of business address, and a list of employees. The SSS will issue an Employer Reference Number (ERN) used for remitting employee contributions. Self-employed individuals may also register as SSS members for retirement and disability benefits.
Obtain Business Permit from Local Government Unit (LGU)
Apply for a Business Permit from your city or municipal government's Business Permits and Licensing Office. Required documents typically include the BIR COR, proof of business address, proof of ownership or lease of business premises, and a completed application form. The permit must be renewed annually. Local business taxes (occupation taxes) are also assessed at this stage and vary by location and business type.
Register for Value-Added Tax (VAT) if Applicable
If your business has annual gross receipts exceeding ₱3,000,000, you must register for VAT within 30 days of exceeding the threshold. File BIR Form 1901-B (Application for VAT Registration) at your RDO. Once registered, you must file quarterly VAT returns (Form 2550Q) by the 25th day after the close of each quarter and maintain detailed sales and purchase invoices for VAT audit purposes.
Register with PhilHealth and Pag-IBIG (if Employer)
If you have employees, register with the Philippine Health Insurance Corporation (PhilHealth) and the Home Development Mutual Fund (Pag-IBIG) within 30 days of hiring. Visit their respective offices with your COR, TIN, and employee list. These agencies will issue employer reference numbers used for remitting employee contributions. Contributions are withheld from employee salaries and remitted monthly.
Apply for BMBE Registration (if Eligible)
If your business has annual gross receipts not exceeding ₱3,000,000, you may apply for Barangay Micro Business Enterprise (BMBE) registration at your barangay hall. BMBE status exempts qualifying businesses from national income tax for the first three years of operation and simplifies compliance requirements. Submit proof of business registration, proof of address, and a barangay certification of operation.
