Buwiz fills in your BIR returns, checks every one against the official eBIRForms rules, reminds you before each deadline, then files it with BIR from your own connection. One TIN, every branch under it, all 43 forms.

- BIR parity
- All 43 BIR forms, checked with the same 2,007 rules as eBIRForms.
- Your data stays yours
- Your books and returns are prepared on your computer and sealed before they leave it. Buwiz keeps the BIR receipt, not your books.
- AI native
- An AI co-worker drafts and checks your returns. You approve every filing.
Everything you file, in one calm window.
Built around how business owners, bookkeepers, and CPAs actually file: pick the taxpayer, open the form, fill only what changed.
Fill the on-screen form on the left and watch the BIR-format paper return update on the right as you type.
Print preview follows your open draft and redraws only the pages you changed, so you can check every comb box and schedule row before you print or file.
Every form is checked with rules built from the official eBIRForms package: 2,007 validations and 623 calculations across 9,592 fields.
Checks run as you type without freezing the window. Each message points at its numbered item, and the 'On this form' sidebar jumps to the next part that needs attention.
Keep one template per form for each branch, then press Tab in Guided Mode to stop only at the fields that change each period.
Templates keep setup answers such as ATCs, tax elections, and categories, never last period's amounts. Turn any filed return into a template with 'Use as template'.
Keep your head office (00000) and branches under one 9-digit TIN. Branches inherit address and RDO until you change them.
Switch taxpayer or branch from the title bar. Each tax year has its own form checklist: copy last year's forms in one click or start from a Non-VAT, VAT, Employer, or Professional starter pack.
See every return due in the next 30 days across your taxpayers and branches, overdue items first.
Home lists overdue and upcoming deadlines with one-click Open, plus recently filed returns you can reuse as templates.
Jump to any taxpayer, branch, recent return, or any of the 43 forms from the keyboard.
Press Cmd+K on macOS or Ctrl+K on Windows and Linux, then search by TIN, name, or form code such as 1601C, 2550Q, or 1701.
One Buwiz account. Your TIN stays yours.
The same account signs you in on the web and in the Buwiz apps, and it is how Buwiz keeps every TIN with its rightful owner.

AI Native Tax Filing
Give the paperwork to Buwiz, your AI co-worker. It works in your apps on your computer: it reads your tax profiles, turns your accountant's spreadsheet into a finished BIR form and checks it, watches your inbox for BIR's confirmation and fills in the bank's payment page. Then it stops and asks. Returns are filed from the Buwiz app and paid on your bank's own page, each only after you confirm.
Install Buwiz from the chat. Log in with Touch ID.
Ask your co-worker to install the Buwiz plugin, then say “Log in with Buwiz”. A login card appears in the chat and your saved password fills it with Touch ID. You choose what the co-worker may do on your account.
One TIN, every branch, as live cards.
A salary, two bakeshops and an apartment: a mixed-income earner keeps them all under one TIN. Ask in plain words and get your branches, the tax year, which branch files which form and what falls due next. Keep any of them as a Mini App.
One spreadsheet for every branch. A finished form for each.
Attach the payroll workbook your accountant sent for all your branches. The co-worker reads it, fills one 1601-C per branch, checks each against every official rule and opens them as BIR prints them, for you to review.
Say “submit”. Approve it. It is queued.
The co-worker checks the form again, asks for permission to publish if you never gave it, and shows you exactly what will be filed. Nothing leaves until you approve, and then it goes to BIR from the Buwiz app on your computer.
A routine watches your inbox for BIR's confirmation.
Install Gmail and ask for a routine. Every minute it looks for BIR's confirmation email; when it arrives, the confirmation comes back as a PDF to print or keep.
Paid online through LandBank, with your OK.
A second routine waits for the confirmation, then opens the bank's payment site on the co-worker's computer and fills in BIR, the form, the period, the ATC and the amount. You log in with Touch ID and approve the amount; the payment itself is made on the bank's page.
Buwiz does the work, then stops and asks. Nothing is filed or paid until you confirm.
Every return runs through BIR's rules again right before it leaves your computer.
Agents connected to your Buwiz account see masked TINs only, and can read it but never change it.
Questions
Do I need a Buwiz account?
Yes. The desktop app asks you to sign in or create a free account the first time it opens. Your account is how Buwiz knows which TINs are yours and keeps each TIN with a single owner.
How does activating a TIN work?
On My TINs, upload your BIR Form 2303, a government ID and any supporting documents. A reviewer checks them by hand, and the TIN becomes active only if the claim is approved. Active TINs unlock filing in the Buwiz app.
How does Buwiz send my return to BIR?
Through your own connection. When you file from the Buwiz app, the return travels to BIR from your computer, so BIR sees you, not us. The app connects only to BIR's own servers, and every filing ends with a signed receipt.
Does the app work offline?
Yes, after that first sign-in, and it stays signed in until you sign out. You need a connection to file a return and to add a TIN.
Is there a mobile app?
Yes, it's coming soon. The Buwiz app is coming to Windows, macOS, Linux, Android and iOS, all with the same Buwiz account.
Can an AI agent file for me?
Buwiz, your AI co-worker, does the work and you approve it. Nothing is filed or paid until you confirm: returns are filed from the Buwiz app on your computer, and payments are made on your bank's own page. Agents connected to your Buwiz account can only read it, and see masked TINs.
