Philippines Tax Compliance Calendar: BIR Filing, Annual Audit AFS and SEC GIS

Why Build a Compliance Calendar the Moment You Register

A common misconception among newly established owners is that once you hold your SEC certificate and BIR tax number, the hard part is over. The opposite is true: the moment registration completes is the moment ongoing filing obligations begin. Philippine tax and corporate governance filings fall due on staggered frequencies, some monthly, some quarterly, some annually, and the deadlines do not line up neatly.

Miss any single deadline and BIR (the tax authority) or SEC (the corporate regulator) will typically impose penalties and surcharges; sustained neglect can affect your company's standing and even its registration status. So the first thing to do after setup is to plot every filing node into a compliance calendar with reminders ahead of each due date. Rather than scrambling afterward, let the Yixing compliance team watch the timeline for you from day one.

Monthly Filings: Withholding on Compensation, Expanded Withholding and Monthly VAT

Monthly is the highest-frequency tier and the one most often missed through oversight. Common monthly BIR filing requirements include:

• Withholding tax on compensation (Form 1601C): as an employer, you file and remit the income tax withheld from staff salaries each month.
• Expanded / final withholding tax (Form 0619-E / 0619-F): monthly remittance of tax withheld on payments such as rent and professional fees.
• Monthly VAT (Form 2550M, where applicable): VAT-registered businesses report VAT on the month's sales.

The moment you hire staff, withholding on compensation almost always applies; if you also pay landlords or consultants, withholding tax is triggered too. Monthly filings interlock, so a single missed month leaves your quarterly and annual summaries out of balance, and the trouble snowballs.

Quarterly Filings: Quarterly VAT, Income Tax and Withholding Summaries

After each quarter closes, a set of summarizing returns falls due:

• Quarterly VAT (Form 2550Q): reconciles output and input VAT for the quarter.
• Quarterly income tax (Form 1702Q): the corporation prepays income tax on the quarter's taxable income.
• Quarterly withholding summary (Form 1601-EQ / 1601-FQ): a consolidated return of expanded / final withholding tax for the quarter.

The core logic of quarterly filing is reconciliation, and it is built on your monthly data. Keep the monthly bookkeeping clean and the quarterly stage goes smoothly. The regular corporate income tax rate is 25%, with 20% available to qualifying smaller companies; VAT is 12%. Which rate applies depends on company size and taxable income and must be worked out case by case.

Annual Filings: Income Tax, Withholding Summaries and the Statutory Audit (AFS)

The annual tier is the heaviest on the calendar and usually the most time-consuming:

• Annual income tax return (Form 1702): the final reckoning of the fiscal year's taxable income, settling any balance due or refund.
• Annual withholding summaries (Form 1604-C / 1604-E): consolidated reporting of the year's withholding on compensation and expanded withholding, with certificates issued to employees and suppliers.
• Statutory Audited Financial Statements (AFS): financial statements audited by an independent CPA, filed to both BIR and SEC. This is the centerpiece of annual compliance and needs your books prepared months in advance.

The AFS rests on clean bookkeeping across the whole year. If your records are scattered or long-neglected, you may find the audit simply cannot be completed near the deadline. Because annual filing involves tax computation and audit coordination, it is best handled by a professional compliance team.

Corporate Governance: SEC GIS and Business Permit Renewal

Beyond tax, the corporate governance layer has fixed annual actions that companies fixated on BIR alone tend to overlook:

• SEC General Information Sheet (GIS): an annual update to the SEC of stockholders, directors, registered address and other core company details.
• Business permit (Mayor's Permit) renewal: renewed annually with your city government, typically in January, with penalties that accrue if you are late.

These run in parallel with tax filings and do not substitute for one another. January is often a pinch point where permit renewal stacks on top of several early-year returns; if you are also handling staff hiring and employment compliance at the same time, a thin team can easily drop the ball, which is exactly why a calendar planned ahead pays off.

Maintaining Books of Accounts and Catch-up Bookkeeping

Everything above rests on your Books of Accounts. The Philippines requires companies to maintain BIR-registered books that faithfully record every receipt and disbursement. These books are not just a bookkeeping tool; they are the core basis for tax audits and the annual statutory audit.

In practice, many companies get so busy in their early stage that bookkeeping is neglected, only to find the records blank when a return or audit is due. That is when catch-up bookkeeping is needed, reconstructing months or even years of vouchers into the books and then filing the outstanding returns on that basis. Catch-up gets more expensive and harder the longer it is delayed, so the earlier you act, the more you save. If your books have already fallen behind, have Yixing scope the catch-up first, close the gap, then fold everything into a normal compliance calendar.
