SAWT DAT File vs Physical BIR Form 2307: Do You Still Need to Keep the Certificates?
No — submitting a SAWT DAT file does not retire the physical BIR Form 2307 certificates it summarizes. SAWT (Summary Alphalist of Withholding Agents of Income Payments Subjected to Withholding Tax at Source) is a machine-readable index of certificates a payee received during the period; the certificates themselves generally still need to be retained and remain the underlying proof the BIR checks a claim against.

Why doesn’t the SAWT DAT file replace the certificates? #
SAWT exists to summarize, not substitute, because the BIR verifies a creditable withholding tax claim against more than one taxpayer’s records. The written-statement requirement behind BIR Form 2307 comes from the NIRC itself:
“Every person required to deduct and withhold any tax under this Chapter shall furnish to the payee… a written statement showing the income or other payments made… and the amount of the tax deducted and withheld therefrom.”
— NIRC, Section 58(B)
A SAWT DAT file lets a payee submit that information in bulk, alphalist-style, rather than attaching every individual certificate to a return. But because the same underlying certificate data also has to reconcile against the withholding agent’s own submitted alphalist (filed separately as that agent’s QAP or annual alphalist), the certificate itself stays the reference document both sides can be checked against — the SAWT entry is a claim built on the certificate, not a stand-in for it.
What did RR No. 2-2015 actually change? #
RR No. 2-2015 changed the submission format for large taxpayers, not the retention obligation. Before the regulation, large taxpayers attaching BIR Form 2307 certificates to their SAWT filing submitted physical hard copies. Under RR No. 2-2015, large taxpayers instead submit scanned copies of BIR Form 2307 (and, separately, BIR Form 2316) as the SAWT attachment. RMC No. 24-2015 clarified the rule further: the shift to scanned copies does not remove the underlying obligation to retain the original hard copies, which taxpayers must still be able to produce if the BIR asks for them during an audit.
What changed and what didn’t:
| Before RR No. 2-2015 | Under RR No. 2-2015 / RMC No. 24-2015 | |
|---|---|---|
| What’s submitted with SAWT (large taxpayers) | Physical hard copies of Form 2307 | Scanned copies of Form 2307 |
| Retention of original hard copies | Required | Still required |
| Non-large taxpayers | Not directly covered by this format change | Generally continue existing practice unless separately mandated |
The practical effect for most taxpayers who aren’t classified as large taxpayers is limited — the core point that matters across the board is that a SAWT filing is a summary layered on top of certificates that still need to exist and be retrievable, whichever submission format applies.
A worked example: a claim that doesn’t match #
A consulting firm files its annual income tax return claiming P620,000 in creditable withholding tax, supported by a SAWT DAT file listing eleven client certificates. During processing, the BIR cross-checks one entry — a P90,000 certificate attributed to a client — against that client’s own annual alphalist of payees, and finds no matching entry: the client never actually filed that payment in its alphalist.
- SAWT claim for that certificate: P90,000 in creditable withholding tax
- Client’s alphalist filing: no corresponding entry
- Result: the P90,000 credit is at risk of disallowance until the consulting firm produces the actual BIR Form 2307 certificate and, if needed, follows up with the client to correct its own alphalist filing
This is exactly why the certificate matters even after it’s been summarized in a SAWT file — the DAT file makes the claim easy to submit, but the certificate (and the withholding agent’s own matching filing) is what resolves a discrepancy like this one. For what to do when the missing piece is the certificate itself rather than a client’s filing gap, see SAWT Missing or Late BIR Form 2307.
Frequently asked questions #
Does filing a SAWT DAT file mean you no longer need the physical BIR Form 2307 certificates? #
No. The SAWT DAT file is a machine-readable summary of the certificates a taxpayer received, not a replacement for them. The underlying BIR Form 2307 certificates generally still need to be kept as supporting documentation and are subject to verification against the withholding agents’ own alphalist filings.
Do large taxpayers still submit paper copies of Form 2307 with SAWT? #
Under Revenue Regulations No. 2-2015, large taxpayers submit scanned copies of BIR Form 2307 as the SAWT attachment instead of physical hard copies, but they are still required to retain the original hard copies for presentation during a BIR audit, as clarified in RMC No. 24-2015.
What happens if the BIR can’t match a SAWT entry to an actual certificate? #
A SAWT entry that doesn’t correspond to a certificate the withholding agent actually issued and reported can be disallowed as a credit, since the BIR verifies claimed creditable withholding tax against the withholding agents’ own alphalist submissions, not solely against the payee’s SAWT listing.
Is SAWT the same thing as BIR Form 2307? #
No. BIR Form 2307 is the individual certificate a withholding agent issues to a payee for a specific transaction or period. SAWT (Summary Alphalist of Withholding Agents) is the payee’s own consolidated DAT file listing every certificate received, used to support a creditable withholding tax claim.
How long should you keep BIR Form 2307 certificates? #
BIR Form 2307 certificates should be kept as part of a taxpayer’s accounting and tax records, retained for the same period other supporting tax documents must be preserved for possible BIR examination — treat them as records to keep, not as documents that can be discarded once summarized in a SAWT filing.
Summary #
A SAWT DAT file is a consolidated index built from BIR Form 2307 certificates, not a replacement for them — the certificates still need to be retained, and for large taxpayers, RR No. 2-2015 only changed the submission format to scanned copies while RMC No. 24-2015 kept the original hard-copy retention requirement in place. When a SAWT entry and a withholding agent’s own alphalist don’t line up, the certificate is the document that resolves the discrepancy. See SAWT Reconciliation With BIR Form 2307 for how that matching process works in practice.
