SAWT in BIR Online Tools: How It Works

SAWT — the Summary Alphalist of Withholding Taxes — is a required attachment that lists every payee a taxpayer withheld tax from during a filing period. BIR Online Tools’ SAWT module converts a filled-in Excel workbook into a BIR-ready DAT file for nine different BIR returns, from individual income tax to VAT to percentage tax.

This guide is part of the App Guide series and gives an overview of the SAWT module before diving into a specific form. For BIR Form 2307 — the certificate that documents the withholding a SAWT alphalist later summarizes — see the BIR Form 2307 series.

What does the SAWT module cover? #

SAWT is filed as an attachment to nine different BIR returns, and BIR Online Tools gives each one its own dedicated converter reachable from the SAWT hub page.

How does the SAWT workflow work? #

Every SAWT form uses the same three-step conversion flow, so once you’ve used one, every other form works identically:

1. Download the Excel template for the specific form you’re filing — each template ships with example detail rows already filled in, so you can see the expected format before entering real data.
2. Fill in your payee entries — TIN, ATC, nature of income payment, amount, and tax withheld for each payee — and save the workbook.
3. Upload the completed file. BIR Online Tools reads every row, validates it, and shows any errors before letting you convert. A passed workbook shows parsed totals and a Download DAT File button, and the file auto-saves to your DAT Repository.

Withholding agent details — TIN, branch code, and RDO code — come from your active company profile, so they don’t need to be re-entered per form.

Which form should you start with? #

Pick the form that matches the return you’re actually filing:

• BIR Form 1700 — compensation-income earners filing annually
• BIR Form 1701Q and BIR Form 1701 — individuals, estates, and trusts filing quarterly or annually
• BIR Form 1702Q and BIR Form 1702 — corporations and partnerships filing quarterly or annually
• BIR Form 2550M and BIR Form 2550Q — VAT-registered taxpayers filing monthly or quarterly
• BIR Form 2551Q — percentage-tax filers
• BIR Form 2553 — corporations and partnerships exempt from income tax

Frequently asked questions #

What is SAWT? #

SAWT stands for Summary Alphalist of Withholding Taxes, a required attachment that lists every payee a taxpayer withheld tax from during a filing period, including each payee’s TIN, Alphanumeric Tax Code (ATC), nature of income payment, amount paid, tax rate, and tax withheld.

Which BIR forms require a SAWT attachment? #

BIR Online Tools’ SAWT module covers BIR Form Nos. 1700, 1701Q, 1701, 1702Q, 1702, 2550M, 2550Q, 2551Q, and 2553 — spanning individual and corporate income tax returns, VAT declarations, percentage tax returns, and exempt-corporation returns.

Is the SAWT workflow the same for every form? #

Yes. Every SAWT form in BIR Online Tools uses the same three-step flow — download an Excel template, fill in payee entries, upload the completed file — even though each form’s template is scoped to that specific return’s SAWT requirements.

Do I need a different company profile for each SAWT form? #

No. Every SAWT form pulls withholding agent details from the same active company profile set once under Company Info, so switching between forms doesn’t require re-entering your registration details.

What happens after a SAWT workbook passes validation? #

A passed workbook shows parsed row counts and computed totals, then lets you download a BIR-ready DAT file named to BIR convention; the file is also saved automatically to your DAT Repository.
