Philippines Company Bookkeeping and Tax Filing Steps: Registration First, Then Monthly, Quarterly and Annual

The overall order: foundations first, then three layers

Bottom line: bookkeeping and tax filing is a chain, not one form due on one date. Skip a step and the next has nothing to stand on. Think of it in two parts: registration is done once (and updated when details change), then a loop of three layers runs in parallel.

1. Foundation: after SEC registration, register with the BIR at the Revenue District Office (RDO) covering your registered address, register your books, and obtain invoicing authority.
2. Monthly: record transactions and remit any withholding taxes.
3. Quarterly: once the books are up to date, file VAT or percentage tax, the income tax prepayment and the withholding summaries.
4. Annually: annual income tax, financial statements and the corporate filings.

Monthly work manages the flow, quarterly work settles, annual work finalises. The quality of the annual filing depends on how well every month was booked; see the three-layer rhythm for that relationship, and the first-year walkthrough for a new company's route.

Step one: registration, books and invoicing authority

Bottom line: these three items are the entry ticket for every later filing, and their order matters.

Tax registration: the RDO follows your registered address

SEC registration only gives the company legal personality. Before trading, register with the BIR at the RDO with jurisdiction over your registered address. The result is the Certificate of Registration (COR, Form 2303) and your registered tax types; companies and partnerships use BIR Form 1903. Where you go depends on the district your registered address falls in, not where the office actually sits or where the owner lives. RDO directories and opening hours change, so use the BIR website.

Books of accounts: register first, record second

Books must be registered with the BIR. Online registration goes through the Online Registration and Update System (ORUS), which produces a QR Stamp for the first page of the book; offline registration uses BIR Form 1905 with documents that vary by type of book. Register before you start recording. Keeping a spreadsheet for a few months and copying it into a registered book at year end does not repair the gap in the legal record for that period.

Invoicing authority: authority first, invoices second

Only after the Authority to Print (ATP) is granted can you print and issue invoices or receipts, and printing takes time. For the document list, see the opening materials checklist.

Step two: the monthly routine

Bottom line: every month you must keep the books, and remit withholding taxes if you have a withholding duty. Monthly VAT returns are now voluntary.

1. Collect the month's sales, purchase, bank and expense documents and post them to the registered journal and ledger.
2. Decide whether you had a withholding duty: you paid salaries, or paid certain payees and had to withhold.
3. If so, prepare and file the matching form from the table below.
4. Keep the filing confirmation and payment proof, and file them away.

Once a company pays salaries or certain payees it becomes a withholding agent, and the return is filed in the company's name with the company bearing the responsibility. VAT is now filed quarterly by law; switching between monthly and quarterly filing carries no penalty, but the quarterly return must still be filed on time. Monthly due dates follow the BIR's current rules and are not copied here.

Step three: the quarterly routine

Bottom line: the quarter is about reconciliation, and its numbers come from the monthly books. If the books are unfinished, the quarterly return can only be an estimate. First reconcile the month-by-month entries, then decide between VAT and percentage tax, then prepare the quarterly returns and withholding summaries, and finally handle the income tax prepayment. Usual deadlines:

• 2550Q (quarterly VAT): within 25 days after quarter end.
• 2551Q (percentage tax, for non-VAT-registered businesses): within 25 days after quarter end.
• 1601-EQ / 1601-FQ (quarterly withholding summaries): the last day of the month after quarter end, with attachments where applicable.
• 1702Q (corporate quarterly income tax): within 60 days after each of the first three quarters.
• 1701Q (sole proprietors and self-employed): 15 May for the first quarter, 15 August for the second, 15 November for the third.

Three details trip people up. VAT and percentage tax are alternatives depending on registration type and sales threshold, so do not file both or neither; the thresholds follow the BIR's current publications. Quarterly income tax is a prepayment, not the final settlement; the annual 1702 settles it. And a quarter with no business still needs a nil return on time. If your fiscal year is not the calendar year, shift every quarter to your own fiscal months. The full-year table is in the tax calendar; all dates above are usual timings and the BIR's current publications prevail.

Step four: the annual routine

Bottom line: the annual layer has the longest chain and the most parties: the company, the accountant, the independent auditor and more than one receiving office. Plan it early. There are usually three kinds of filing:

• Annual income tax: the computation and supporting schedules.
• Annual financial statements: once certain conditions are met they must be audited and signed by an independent CPA. Who must be audited, and at what threshold, follows current BIR and SEC publications; do not copy old figures.
• Corporate filings: the SEC audited financial statements (AFS) and the General Information Sheet (GIS). The AFS deadline follows the SEC circular for that year. The GIS follows your own annual stockholders' meeting and is due within 30 calendar days after the meeting, so there is no single nationwide date.

If your fiscal year is not the calendar year, annual income tax falls on the 15th day of the 4th month after year end, which is where groups following a foreign parent's year most often miscalculate. The business permit renewal belongs to the local government, not the BIR. Annual work is usually priced separately from the monthly fee; see how a bookkeeping quote is built for the structure. This page does not quote any amounts.

Closing each cycle: who files, what to keep, for how long

Bottom line: filing is only half the job. Keep the confirmation and the records, because an audit starts by testing books against documents and documents against books.

• Who files: routine returns can be filed through eFPS or eBIRForms, provided the signatory is the registered authorised person. Which forms go through which system, and whether an RDO visit is needed, follows the BIR's current rules.
• What to keep: the filing confirmation and payment proof, stored with that period's books.
• How long: under the BIR's EOPT implementing rules (RR 7-2024), books and related accounting records are kept for 5 years from the day after the filing deadline; paper for manual or loose-leaf books, electronic files for computerised books. If there is a pending protest, audit or refund case, keep the related records until it closes, even after 5 years.

Whether you do it yourself, use a part-time accountant or outsource, the company itself must hold three things: its BIR registration documents and registered books, each period's returns and payment proof, and the BIR and SEC online accounts. For what outsourcing covers and how to change agents without a gap, see tax agent and outsourced bookkeeping.

Where this is slower or wastes effort

• No universal turnaround number: how long registration takes varies by district and by how complete your documents are. This page gives no day counts, only deadline rhythms you can verify against current BIR publications.
• Wrong order costs the most: invoicing without valid authority means early invoices may not be accepted by customers and must be replaced; recording before the books are registered leaves a gap that later copying cannot fill.
• A nil return is not a shortcut: you still file, still keep the books and still maintain your registrations.
• Doing it yourself has a ceiling: annual statements that need a CPA's signature, and a learning cost that tends to land in the first year.
• Catch-up gets harder the longer you wait: if the books have fallen behind, first map which periods have gaps, then decide how to fill them.
• Dates change: deadlines and thresholds in older guides cannot be copied.

For individual cases involving audit notices, penalties or disputes, consult a practising lawyer or accountant; this page is not legal or tax advice, and decisions rest with the competent authority. To turn this cycle into a dated action table with named owners, see compliance support.

Official sources

For forms, current deadlines and the RDO directory, use the official BIR website. If your company employs foreigners, the employment permit (AEP) sits on the labour and immigration track rather than the BIR's; the official entry point is the labour department website, and the explainer is the AEP guide. Confirm everything against current official announcements.
