Tax Compliance Services for Philippine Businesses
Tax compliance in the Philippines is not a single annual task. A registered corporation files monthly withholding tax returns, quarterly income and VAT returns, and an annual ITR with audited financial statements. In parallel, it maintains books of accounts, submits alphalists and SAWT attachments, and renews its BIR registration every January. Each obligation has a specific BIR form, a specific deadline, and a specific penalty for missing either.
STLAF’s CPAs manage this entire compliance cycle on behalf of Philippine businesses. Our lawyers review BIR positions on contentious items and step in when BIR inquires. One engagement covers both the filing function and the legal exposure. Contact us to request a tax compliance review.
Corporate Income Tax Compliance
Annual Income Tax Return (ITR), BIR Form 1702
Every corporation registered in the Philippines must file BIR Form 1702 by April 15 following the close of the calendar year, or by the 15th day of the fourth month following the close of a fiscal year. The annual ITR must be accompanied by audited financial statements prepared by an independent CPA.
The Philippines follows a pay-as-you-file system. Quarterly income tax payments made during the year are credited against the annual tax due. If total quarterly payments exceed the annual liability, the excess may be carried forward or applied for refund.
Under the CREATE Act (RA 11534), the standard corporate income tax rate is 25%. Micro, small, and medium enterprises with taxable income not exceeding PHP 5 million and total assets not exceeding PHP 100 million are taxed at 20%.
Quarterly Income Tax Returns, BIR Form 1702-Q
Three quarterly income tax returns are required each year: Q1 (January to March), Q2 (April to June), and Q3 (July to September). Q4 is covered by the annual ITR. Each quarterly return must be filed and paid within 60 days after the close of the taxable quarter.
Quarterly payments are computed based on cumulative income from the start of the year. The amount paid in Q3 is deducted from the final annual tax due.
Alphalist and SAWT Requirements
Two of the most error-prone compliance attachments are the Monthly Alphalist of Payees (MAP) and the Summary Alphalist of Withholding Tax at Source (SAWT).
The MAP is submitted by withholding agents as an attachment to monthly withholding tax returns. It lists every payee from whom tax was withheld during the month, including their TIN, name, income payment, and tax withheld.
SAWT is submitted by income earners as an attachment to quarterly and annual income tax returns. It summarizes all the BIR Form 2307 certificates received from customers who withheld tax on payments to you. The SAWT totals must match the creditable withholding tax claimed in the ITR, any mismatch triggers disallowance of credits or a BIR deficiency assessment.
Both MAP and SAWT must be submitted in DAT file format using the BIR Alphalist Data Entry Module (version 7.0 or later). Electronic submission is via esubmission@bir.gov.ph. Errors in TINs, mismatched totals, or incorrect file formats result in rejected submissions, with full penalties still applied.
Withholding Tax Compliance
Withholding tax is the single most common trigger for BIR deficiency assessments. The withholding agent, the party making the payment, is legally responsible for deducting the correct amount and remitting it to BIR on time. If the withholding agent fails to withhold, BIR holds the payor liable, not the payee.
Expanded Withholding Tax (EWT), BIR Form 1601-EQ
EWT applies to income payments made to local suppliers, contractors, professionals, and other payees subject to creditable withholding. Common rates are 1% to 2% on goods and services purchased from suppliers, with higher rates for professional fees, commissions, and rentals.
Monthly EWT remittances are filed using BIR Form 0619-E, due by the 10th to 19th of the following month. Quarterly consolidated returns use BIR Form 1601-EQ. The annual alphalist (BIR Form 1604-E) is due by March 3.
Businesses designated as Top Withholding Agents (TWA) by BIR must withhold on all purchases regardless of supplier type. If your customer is a TWA, they withhold before paying you, the BIR Form 2307 they issue serves as your tax credit certificate.
Final Withholding Tax (FWT), BIR Form 0619-F
FWT applies to passive income including dividends, interest, royalties, and prizes. Unlike EWT, which the payee credits against annual income tax due, FWT is final: the tax withheld is the full tax. No further filing is required from the payee on that income.
Monthly FWT remittances use BIR Form 0619-F. The annual alphalist (BIR Form 1604-F) is due January 31. FWT also applies to payments to non-resident foreign corporations (NRFC) and individuals, rates vary depending on the applicable tax treaty.
Withholding Tax on Compensation (WTC), BIR Form 1601-C
Every employer must withhold income tax from employee salaries and remit it to BIR monthly using BIR Form 1601-C, due by the 10th to 17th of the following month. The annual alphalist of employees (BIR Form 1604-C) is due by January 31 of the following year.
Under the TRAIN Law (RA 10963) revised schedule, employees earning PHP 250,000 or less annually are exempt from income tax. Progressive rates from 15% to 35% apply to higher income brackets. Employers must use the current withholding tax table, outdated tables are a common source of over- or under-withholding that surfaces at annual reconciliation.
VAT and Other Regular Filings
Businesses registered for VAT file BIR Form 2550M (monthly) and BIR Form 2550Q (quarterly). The monthly return covers output tax on sales and input tax on purchases. The quarterly return reconciles the cumulative VAT position for the quarter.
Businesses below the PHP 3 million VAT threshold, or those engaged in VAT-exempt transactions, file percentage tax using BIR Form 2551Q instead. The standard percentage tax rate is 3% of gross sales or receipts.
The EOPT Act (RA 11976, 2024) introduced taxpayer classifications by size, micro, small, medium, and large enterprises, with compliance requirements calibrated accordingly. For a full treatment of VAT obligations, the VAT-exempt versus zero-rated distinction, and VAT refund applications, see our VAT and indirect tax services page.
BIR Registration and Housekeeping
Certificate of Registration (COR)
The Certificate of Registration (COR) is the primary BIR document confirming your business is registered to pay specific tax types. It must be displayed at your place of business. Any change to registered details, address, business activity, tax types, requires an amendment through BIR Form 1905 at your Revenue District Office (RDO).
Books of Accounts Registration and Stamping
All taxpayers must register their books of accounts with the BIR before use. Since the introduction of ORUS (Online Registration and Update System, RMC 3-2023), books are registered online. BIR generates a QR code that replaces the previous manual stamping process.
Three formats are accepted: manual (hand-written journals and ledgers), loose-leaf (printed from accounting software, bound at period end), and computerized (fully digital, requiring a BIR Permit to Use). Loose-leaf and computerized books require annual renewal:
- Loose-leaf books: within 15 days after the taxable year ends
- Computerized books: within 30 days after the taxable year ends
- Annual inventory list: January 30
Annual renewal is required regardless of whether the books were actively used during the year.
Annual Registration Fee, BIR Form 0605
Every registered taxpayer pays a PHP 500 annual registration fee by January 31 of each year using BIR Form 0605. The fee is small; the compliance record is not. BIR tracks non-payment and may flag taxpayers with outstanding fees during audit or business permit renewal.

Frequently Asked Questions
What BIR forms does a Philippine corporation need to file?
The core corporate filing obligations include BIR Form 1702 (annual ITR), BIR Form 1702-Q (quarterly ITR, three times per year), BIR Form 0619-E and 1601-EQ (monthly and quarterly EWT), BIR Form 1601-C (monthly WTC), and BIR Forms 2550M and 2550Q (monthly and quarterly VAT). Annual alphalists, Forms 1604-C, 1604-E, and 1604-F, and SAWT are required attachments. The specific forms applicable depend on the tax types registered in your Certificate of Registration.
What happens if I miss a BIR filing deadline?
Late filing triggers a 25% surcharge on the unpaid tax amount, plus 12% annual interest computed from the original due date to the actual payment date. A compromise penalty also applies, from PHP 200 to PHP 50,000 depending on the type and severity of the violation. These amounts compound: a missed PHP 10,000 obligation becomes PHP 12,500 or more within months.
What is SAWT and how do I submit it?
SAWT (Summary Alphalist of Withholding Tax at Source) is a required attachment to your quarterly and annual income tax returns. It lists all customers who withheld tax on payments to you, their TINs, the income paid, and the tax withheld, matching the BIR Form 2307 certificates they issued. Submission must be in DAT format via esubmission@bir.gov.ph. Errors in TINs or totals result in disallowance of tax credits.
Do I still need to file a BIR return if I have zero income?
Yes. All registered taxpayers must file returns for each covered period regardless of income or business activity. Filing a zero-return is required. Failure to file, even with zero liability, results in non-filing penalties.
What are books of accounts and when do I renew them with BIR?
Books of accounts are your official accounting records registered with BIR. Since 2023, all books must be registered via ORUS (Online Registration and Update System), which generates a QR code confirming registration. Loose-leaf books must be renewed within 15 days after the taxable year ends; computerized books within 30 days. The annual inventory list is due January 30.
What is the difference between EWT and withholding tax on compensation?
EWT (Expanded Withholding Tax) applies to payments made to suppliers, contractors, and professionals, remitted using BIR Form 0619-E monthly and 1601-EQ quarterly. WTC (Withholding Tax on Compensation) applies to employee salaries, remitted monthly using BIR Form 1601-C. They use different forms, different rates, and different alphalists. Misclassifying a payment between the two is a common audit finding.
What is the BIR annual registration fee?
PHP 500 per year, filed using BIR Form 0605, due January 31. The fee applies to all registered taxpayers regardless of size or revenue. Non-payment is a minor but trackable compliance violation that BIR may flag during audit or business permit renewal.
