What's the fastest way to know which BIR DAT file applies to me?

Start with your VAT registration status and your role as a withholding agent. VAT-registered taxpayers generally file RELIEF SLSP; anyone who withholds creditable tax on purchases files QAP; anyone who has creditable tax withheld from their own income uses SAWT to support their refund or credit claim; and employers plus withholding agents both file some version of the annual Alphalist.

Can one business have to file all four — RELIEF, SAWT, QAP, and Alphalist — at the same time?

Yes. A VAT-registered business that also withholds tax on supplier payments and pays its own employees can be required to file RELIEF SLSP (as a VAT-registered seller/buyer), QAP (as a withholding agent), SAWT (to support its own creditable withholding tax claims), and the annual Alphalist (covering both employees and payees), because each filing responds to a different role the same taxpayer can hold simultaneously.

What's the difference between QAP and SAWT if both involve BIR Form 2307?

QAP is filed by the withholding agent who issued BIR Form 2307 certificates to its payees, listing the payments it made and the tax it withheld. SAWT is filed by the payee who received those BIR Form 2307 certificates, listing the creditable withholding tax it wants to claim against its own income tax or VAT liability. They describe the same certificates from opposite sides of the transaction.

Is the annual Alphalist the same as QAP or SAWT?

No. QAP and SAWT are quarterly filings tied to specific withholding tax returns. The annual Alphalist (covering BIR Form 1604-C for employees, 1604-E for payees subject to expanded withholding tax, and 1604-F for final withholding tax) is a once-a-year summary that consolidates a full calendar year of withholding activity, filed on a different schedule from the quarterly submissions.

Does a business with no transactions in a quarter still need to file these DAT submissions?

Generally yes, for the filings that otherwise apply to that taxpayer — most of these obligations require a nil or zero-transaction filing rather than simply skipping the period, though the exact nil-filing mechanics differ by return. See the dedicated post on nil filing for RELIEF, SAWT, and QAP for the specifics.

RELIEF, SAWT, QAP, or Alphalist: Which BIR DAT File Do You Actually Need to File?

RELIEF SLSP, SAWT, QAP, and the annual Alphalist are four separate BIR DAT file submissions, and which ones apply to a given business depends on two questions: are you VAT-registered, and are you a withholding agent, a withheld-upon payee, or an employer? Many taxpayers file more than one of these at once, because the questions aren’t mutually exclusive — a single VAT-registered company that also withholds tax on suppliers and pays employees can end up filing all four.

The four filings at a glance #

Each of these four BIR submissions answers a different question about the same underlying transactions, which is exactly why a single business can be required to file more than one.

Filing	Who files it	What it reports	Typical schedule
RELIEF SLSP	VAT-registered taxpayers	Summary lists of sales and purchases, to cross-match VAT-relevant transactions	Quarterly
QAP	Withholding agents	Payments made and creditable tax withheld from payees (the source of BIR Form 2307)	Quarterly
SAWT	Payees claiming creditable withholding tax	BIR Form 2307 certificates received, supporting a tax credit claim	Quarterly, alongside the payee’s own return
Alphalist (1604-C/E/F)	Employers and withholding agents	Annual summary of compensation and withholding tax activity for the full calendar year	Annually

The legal basis for RELIEF SLSP traces to BIR Revenue Regulations No. 1-2012, whose caption states its purpose directly:

“REQUIRING THE MANDATORY SUBMISSION OF QUARTERLY SUMMARY LIST OF SALES AND PURCHASES (SLSP) BY ALL VAT REGISTERED TAXPAYER THEREBY AMENDING SECTION 4.114-3 OF REVENUE REGULATIONS NO. 16-2005, AS AMENDED”

Question 1: Are you VAT-registered? #

If you’re a VAT-registered taxpayer, RELIEF SLSP applies to you regardless of whether you withhold tax from anyone else. RELIEF exists to let the BIR cross-match what sellers report as sales against what buyers report as purchases, catching under-declared revenue or over-claimed input VAT. Non-VAT (percentage tax) taxpayers don’t file RELIEF SLSP — but they may still have obligations under the other three filings below, since VAT status and withholding-agent status are independent questions.

Question 2: Do you withhold creditable tax from anyone you pay? #

If you’re a designated withholding agent — a corporation, a top withholding agent, or an individual meeting the relevant threshold — and you issue BIR Form 2307 certificates to suppliers, professionals, or lessors, you file QAP to report those payments and the tax withheld. See Who Must File QAP? for the specific withholding-agent criteria. QAP is filed from the payor’s side of a BIR Form 2307 transaction.

Question 3: Does anyone withhold creditable tax from payments to you? #

If clients or customers withhold tax from what they pay you and hand you a BIR Form 2307 certificate in return, you file SAWT to list those certificates and claim the withheld amount as a credit against your own income tax or VAT liability. SAWT is the payee’s mirror image of QAP — the same certificate appears in the withholding agent’s QAP as an amount paid out, and in the payee’s SAWT as an amount to be credited. See SAWT Reconciliation: Matching Your SAWT to Your BIR Form 2307 Certificates for how the two sides should line up.

Question 4: Do you have employees or issue any final/creditable withholding certificates over the full year? #

Regardless of your VAT status, if you pay employees or act as a withholding agent at any point in the year, you have an annual Alphalist obligation — BIR Form 1604-C for compensation paid to employees, 1604-E for payments subject to expanded withholding tax, and 1604-F for payments subject to final withholding tax, each with its own accompanying alphalist. This is separate from and in addition to the quarterly QAP filings covering the same withholding activity, because the Alphalist consolidates a full calendar year rather than a single quarter.

Worked example: one company, three filings #

Take a mid-sized VAT-registered trading company that also employs 15 staff and pays several suppliers subject to expanded withholding tax. Over the course of a year, this single business:

Files RELIEF SLSP every quarter, because it’s VAT-registered and has sales and purchases to report.
Files QAP every quarter, because it withholds tax from suppliers and issues them BIR Form 2307 certificates.
Files the Alphalist (1604-C for its 15 employees, 1604-E for its withheld-upon suppliers) once a year, consolidating the same withholding activity QAP already reported quarterly.
Does not file SAWT this year, because none of its own clients withheld tax from payments to the company — SAWT only applies if this company were on the receiving end of a BIR Form 2307.

Change one fact — say the company also earns professional consulting fees from clients who withhold tax and issue it BIR Form 2307 — and SAWT becomes a fourth obligation, because the company is now simultaneously a withholding agent (QAP) and a withheld-upon payee (SAWT) for different transactions in the same period.

Summary #

RELIEF SLSP, QAP, SAWT, and the annual Alphalist each answer a different question about a taxpayer’s transactions: are you VAT-registered, do you withhold tax from others, does anyone withhold tax from you, and do you have a full year of compensation or withholding activity to consolidate. Because these roles aren’t mutually exclusive, many mid-sized and larger businesses end up filing several — sometimes all four — in parallel, which is why checking each question separately, rather than assuming one filing covers the others, is the safest way to confirm your actual DAT file obligations.
