How to Generate a SAWT DAT File for BIR Form 1702

BIR Form 1702 is the annual income tax return for corporations and partnerships. BIR Online Tools’ SAWT module converts a filled-in Excel workbook of withheld-from payees into a BIR-ready DAT file for this return, using the same download-fill-upload-convert flow as every other SAWT form.

This guide is part of the SAWT overview in the App Guide series. For the quarterly version of this return, see BIR Form 1702Q.

How do you generate a SAWT DAT file for BIR Form 1702? #

1. Download the Excel template #

Open the BIR Form 1702 SAWT converter and click Download Excel Template. The template ships with example detail rows already filled in, so you can see the expected format before replacing them with real payee data.

2. Fill in your payee entries and upload #

Replace the example rows with your own payee TINs, ATCs, income payments, and tax withheld for the year, save the file, then click Upload Excel File and select it. BIR Online Tools reads every row before validating.

3. Review the validation results #

A passed workbook shows a Validation Results — Passed badge, the parsed row count, the return period, and computed totals for income payment and tax withheld.

4. Download the DAT file #

Click Download DAT File. The filename follows BIR convention (<TIN><BranchCode><MMYYYY> plus the form’s DAT type code), and the file is saved automatically to your DAT Repository.

Frequently asked questions #

Who files BIR Form 1702? #

BIR Form 1702 is the annual income tax return for corporations and partnerships, covering the full taxable year’s income tax liability.

How is BIR Form 1702 different from BIR Form 1702Q? #

BIR Form 1702 is the annual return, filed once after the taxable year closes, while BIR Form 1702Q is the quarterly return filed during the year — both use the same SAWT converter pattern in BIR Online Tools, just under separate form-specific templates.

What happens if my uploaded workbook has errors? #

BIR Online Tools reads every row first, then shows a table of every validation error — sheet, row, field, message, and value — before you can generate a DAT file, so you fix everything in one pass instead of one error at a time.

Summary #

Generating a SAWT DAT file for BIR Form 1702 takes four steps: download the example-filled template, replace the rows with your payee data, upload it for validation, and download the resulting DAT file. See the SAWT overview for the other eight forms, or the App Guide hub for every module.
