Does a credit memo cancel the original QAP row for that payee?

No. The original QAP row reflects the income payment and tax withheld as they stood on the date withholding was required, which does not change retroactively just because a later event reduced the invoice. The credit memo creates a second, usually negative, adjustment — either netted into the current quarter's filing or, if the original return is already closed, corrected through an amended return and alphalist for that earlier quarter.

Which quarter absorbs a purchase return: the quarter of the original sale or the quarter of the return?

It depends on timing. If the credit memo is issued and the adjustment is booked before that quarter's BIR Form 1601-EQ and QAP are filed, the withholding agent can simply net the reduced amount into that same quarter's filing. If the original quarter's return was already filed, the correction has to run through an amended return and a corrected QAP for that earlier quarter rather than being absorbed into whichever quarter the credit memo happens to be dated.

Does the supplier need a corrected BIR Form 2307 after a purchase return?

Yes, if the original certificate overstates the income payment or tax withheld once the return is booked. A corrected or replacement BIR Form 2307 showing the adjusted, lower income payment and tax withheld keeps the supplier's own records — and its SAWT or 1701Q credit claim — aligned with the withholding agent's corrected QAP row.

What if the purchase return happens in a later year, after the supplier already claimed the original credit?

The supplier's credit claim for the year the original withholding occurred does not get reopened retroactively just because of a later-year return; the adjustment is handled going forward, in the period the return actually occurs, rather than by amending a return the supplier has already filed and closed.

Does Section 229 of the NIRC apply to a withholding agent that already remitted tax on an amount later returned?

It can, but only for the withholding agent's own recovery of an amount it already remitted to the BIR for a closed period — and only within the law's two-year window measured from the date of that remittance. It does not extend or change the payee's own, separate right to credit the (corrected) withholding against its income tax due.

How to Adjust Your QAP When a Purchase Return or Credit Memo Reduces an Already-Withheld Payment

A purchase return, price adjustment, or credit/debit memo that reduces an invoice after its withholding tax was already remitted does not erase the original Quarterly Alphalist of Payees (QAP) row for that payment — it adds a second, usually negative, adjustment that either nets into the current quarter’s filing or, if the original quarter’s return is already closed, has to run through an amended return and a corrected QAP for that earlier period.

What actually changes when a purchase is returned after withholding was already done? #

A credit or debit memo changes the tax base — the income payment amount — not the withholding rate or the payee’s identity, so the fix is narrower than correcting a wrong ATC or a bad TIN. Expanded withholding tax under Revenue Regulations (RR) No. 2-98, as amended, is computed on the income payment made or accrued to a payee; when a purchase is later returned, or a price is reduced through a credit memo (or increased through a debit memo), the amount actually owed to the supplier changes, and the withholding tax that goes with it should change by the same proportion. This is a different problem from reporting the same payee under two ATCs or from a wrong TIN rejecting a QAP row — here, every field was correct when filed; a later commercial event just changed the amount.

A credit memo is the usual accounting document for this kind of reduction — it references the original invoice, states the reason for the adjustment, and shows the revised amount. A debit memo does the reverse, billing an additional amount after the original invoice. Either one, once booked, changes the figure that the withholding tax computation is based on.

Same-quarter netting vs. cross-quarter amendment: which path applies #

Whether the adjustment can simply be netted into the current quarter’s QAP or has to reopen an earlier quarter’s filing depends entirely on whether that earlier quarter’s BIR Form 1601-EQ and QAP were already submitted. This repo’s companion guide on correcting an over-withheld BIR Form 2307 sets out the same two-path logic for a rate error, and it applies here just as directly to a base-amount error caused by a return or memo:

Still open (same quarter, return not yet filed): If the credit or debit memo is booked before that quarter’s BIR Form 1601-EQ and QAP are due, the withholding agent simply reports the net, adjusted income payment and tax withheld for that payee in the original quarter’s filing — there is nothing to amend because nothing was filed yet on the wrong number.
Already closed (return already filed): If the original quarter’s BIR Form 1601-EQ was already filed with the pre-adjustment figures, the withholding agent needs an amended return for that quarter, paired with a corrected QAP DAT entry showing the adjusted income payment and tax withheld — the adjustment is attributed back to the quarter the original payment belongs to, not folded into whichever later quarter the credit memo happens to be dated.

For the withholding agent’s own right to recover tax it already remitted to the BIR for a closed period, Section 229 of the National Internal Revenue Code (NIRC) governs how long that claim stays open — generally a two-year window measured from the date of remittance — a materially different, and shorter, clock than the ordinary three-year assessment period taxpayers are more used to seeing. This guide uses the general rule rather than quoting the statute’s exact current wording, since the point that matters here is the deadline’s existence, not its precise phrasing.

What happens to the payee’s BIR Form 2307 and its credit? #

The supplier’s BIR Form 2307 is supposed to mirror the same income payment and tax withheld the withholding agent reports on its QAP, so a base-amount adjustment that changes one has to flow through to the other. RR No. 2-98, Section 2.58.3(B) ties the payee’s ability to claim the withheld amount directly to that certificate matching the underlying facts:

“Claims for tax credit or refund of any creditable income tax which was deducted and withheld on income payments shall be given due course only when it is shown that the income payment has been declared as part of the gross income and the fact of withholding is established by a copy of the withholding tax statement duly issued by the payor to the payee showing the amount paid and the amount of tax withheld therefrom.”
— RR No. 2-98, Section 2.58.3(B)

If the original certificate now overstates (or understates) the income payment and tax withheld because of a later return or memo, a corrected or replacement BIR Form 2307 for the adjusted amount keeps the supplier’s SAWT and BIR Form 1701Q credit claim consistent with what the withholding agent actually reports on QAP — otherwise the supplier is left holding a certificate that no longer matches either the invoice trail or the withholding agent’s own alphalist.

Worked example: a returned shipment inside the same quarter #

The supplier below is fictional, illustrating the mechanics rather than an actual transaction.

Avelino Hardware Supply sells ₱200,000 worth of construction materials to a corporate buyer in August 2026, a purchase-of-goods payment subject to the 1% EWT rate under the Top Withholding Agent rules. The buyer withholds ₱2,000 and issues a BIR Form 2307 for that amount. In September, before the buyer’s Q3 2026 BIR Form 1601-EQ and QAP are due, the buyer discovers ₱50,000 worth of the materials were defective and Avelino issues a credit memo reducing the invoice to ₱150,000.

Step	Amount	Tax withheld (1%)
Original invoice (August)	₱200,000	₱2,000
Credit memo (September, defective goods)	(₱50,000)	(₱500)
Net amount reported on Q3 2026 QAP	₱150,000	₱1,500

Because the credit memo was booked before the Q3 2026 return was filed, the buyer reports the net ₱150,000 payment and ₱1,500 tax withheld directly on its Q3 QAP — there is no amended return involved. The buyer also reissues Avelino’s BIR Form 2307 to show ₱150,000 and ₱1,500, replacing the certificate that would otherwise have shown the pre-return figures. Had the credit memo instead arrived in October, after the Q3 return was already filed showing the full ₱200,000 and ₱2,000, the buyer would instead need to amend that Q3 BIR Form 1601-EQ and QAP rather than netting the adjustment into Q4.

Summary #

A purchase return or credit/debit memo changes the income payment amount that expanded withholding tax is computed on, not the ATC or the payee’s identity — so the correction is about which quarter absorbs the adjusted figure. Booked before that quarter’s BIR Form 1601-EQ and QAP are filed, the adjustment nets directly into the original quarter’s numbers; booked after filing, it requires an amended return and a corrected QAP for that same original quarter, consistent with the general two-path correction framework this repo already covers for over-withholding errors. Either way, the supplier’s BIR Form 2307 needs to be reissued to match, since its SAWT and income tax return credit depend on that certificate reflecting the same income payment and tax withheld the withholding agent reports on QAP.
