A Supplier Gets a Downpayment Before the Invoice Is Issued: When Does It Go on Your QAP DAT File?

A downpayment or advance payment to a supplier triggers your obligation to withhold the moment the money leaves your account — not when the supplier eventually issues a full invoice for the completed job or delivered goods — so that downpayment, and the withholding on it, belongs on the QAP for the quarter you actually paid it. Waiting for the final invoice before reporting the earlier downpayment is one of the more common QAP timing mistakes, and it puts the payee’s creditable withholding tax in the wrong quarter relative to when it was actually withheld.

This guide applies the same timing rule this site covers for construction progress billings to downpayments generally. See BIR Form 2307 on Progress Billings and Mobilization Fees for the construction-specific version, and QAP DAT File: What It Is and Who Must File It for QAP basics.

Why does a downpayment trigger withholding before the invoice exists? #

Withholding tax doesn’t wait for a specific document called an “invoice” — it’s triggered by the underlying economic event of payment or accrual, and a downpayment is unambiguously a payment, which is exactly the event RR No. 2-98 Section 2.57.4 names as one of the two possible triggers. The rule, already verified and applied elsewhere on this site to construction progress billings, reads:

“…the obligation of the payor to deduct and withhold the tax under this Section arises at the time an income payment is paid or payable, or the income payment is accrued or recorded as an expense or asset, whichever is applicable, in the payor’s books, whichever comes first.”

A company that wires a 30% downpayment to a supplier before any goods ship or any service starts has satisfied the “paid” branch of this test on that 30% the moment the wire clears — regardless of what the supplier’s invoicing timeline looks like, and regardless of whether the supplier has even issued an official receipt yet for that specific amount.

How does this play out across the QAP’s quarterly structure? #

Because QAP is organized by the quarter withholding actually occurred, a contract that spans a downpayment in one quarter and a final invoice in a later quarter generates two separate QAP entries for the same supplier — one for each quarter a payment or accrual happened — rather than one combined entry dated to the final invoice.

A payor who instead waits for the final invoice and reports the entire contract value in one QAP entry, dated to that final invoice, misstates the quarter for the downpayment and any mid-project billing — understating the earlier quarters’ QAP totals and overstating the final one, which can surface as a mismatch if the BIR or the supplier cross-checks against the supplier’s own SAWT.

Worked example: an equipment order with a staged downpayment #

Coastal Fisheries Corp. orders a ₱500,000 refrigeration unit from a supplier that is a designated Top Withholding Agent payee, paying 40% down in March to secure the order and the remaining 60% in May on delivery.

Coastal Fisheries issues two separate BIR Form 2307 certificates to the supplier — one for ₱2,000 covering Q1, one for ₱3,000 covering Q2 — and reports the supplier in both quarters’ QAP, even though only one purchase order and one final delivery receipt exist for the whole transaction.

Frequently asked questions #

Do I report a downpayment to a supplier on QAP before I receive the final invoice? #

Yes, if tax was withheld on the downpayment when it was paid. The QAP reports creditable withholding tax by the quarter the withholding actually happened, not by the quarter the supplier’s final invoice is dated, and a downpayment that triggers withholding at the moment of payment belongs in that payment quarter’s QAP.

What rule says a downpayment triggers withholding before the invoice exists? #

RR No. 2-98 Section 2.57.4, which says the obligation to withhold arises when an income payment is paid or payable, or accrued or recorded as an expense, whichever comes first. A downpayment is a payment — the “paid” trigger fires the moment cash leaves your account, independent of whether a corresponding invoice has been issued yet.

What if the downpayment is later applied against a bigger invoice — do I withhold again on the full invoice amount? #

No, not on the portion already withheld. Withholding applies once per peso of income payment; the downpayment already withheld is credited against the total contract price, and only the remaining unwithheld balance generates a new withholding obligation when it’s paid or accrued.

Does this apply to a downpayment on a goods purchase, or only to services? #

It applies to both, for any payment subject to creditable withholding tax under RR No. 2-98 — a downpayment on a service contract and a downpayment on a Top Withholding Agent’s goods purchase both trigger withholding at payment, following the same “whichever comes first” rule.

What if the supplier refunds the downpayment because the deal falls through? #

The withholding already remitted on the downpayment doesn’t automatically reverse itself — the payor generally needs to adjust the QAP and the supplier’s BIR Form 2307 for the period, and the supplier would need to address the refunded amount’s withholding credit through its own return, since the BIR doesn’t treat a cancelled transaction as having been un-withheld by itself.

Summary #

A downpayment triggers withholding at the moment it’s paid, under RR No. 2-98 Section 2.57.4’s “whichever comes first” rule — report it on the QAP for the quarter you actually paid it, not the quarter the supplier’s final invoice happens to carry.
