BIR Online Tools for Computer Shops and IT Hardware Retailers
A computer shop that sells PCs, parts, and peripherals while also billing customers for repair and installation labor runs two separate withholding tracks on the vendor side alone — a Top Withholding Agent’s 1% rate on its own goods purchases, and a different 2% rate on any repair service it pays an outside technician to perform. Mixing up the two is a common error precisely because the same shop both buys goods and pays for services every week, and the BIR’s rate structure treats them as entirely separate categories regardless of how closely related the transactions feel in the shop’s own ledger.
Keep Goods and Service Withholding Straight FREE →When does a computer shop withhold tax on its own purchases? #
A computer shop only withholds tax on what it buys from local suppliers once the BIR has classified it as a Top Withholding Agent (TWA) — ordinary retailers below that threshold don’t withhold on inventory purchases at all. Under Revenue Regulations (RR) No. 7-2019, TWA status attaches once a taxpayer’s gross sales/receipts, gross purchases, or claimed deductible itemized expenses reached ₱12,000,000 or more in the preceding taxable year, and the BIR has published that taxpayer on its official TWA list. The obligation starts on the first day of the month following publication — not retroactively, and not merely because a single purchase order happens to be large.
This site’s TWA rules guide covers the classification mechanics in full; the point that matters for a computer shop specifically is that TWA status, once it applies, covers every qualifying local purchase going forward — both the goods a shop stocks for resale and the services it pays outside vendors to perform.
What rate applies to goods versus services? #
A TWA computer shop withholds 1% on local purchases of goods and a separate 2% on local purchases of services, under RR No. 2-98 as amended by RR No. 11-2018 and RR No. 24-2025 — the two rates never apply to the same transaction. BIR Form 2307 for Purchases of Goods sets out the private-sector ATC codes directly:
“A BIR Top Withholding Agent (TWA) must withhold one percent (1%) expanded withholding tax (EWT) on its local purchases of goods and issue BIR Form 2307 to each affected supplier, under Revenue Regulations (RR) No. 2-98 as amended by RR No. 11-2018, RR No. 7-2019 (₱12 million classification threshold), and RR No. 24-2025 (current rate structure). The matching alphanumeric tax codes for private-sector TWAs are WC158 (corporate supplier) and WI158 (individual supplier).”
| Transaction type | Rate | ATC code (corporate / individual) |
|---|---|---|
| Local purchase of goods (laptops, parts, peripherals) from a TWA supplier | 1% | WC158 / WI158 |
| Local purchase of services (contracted repair labor, installation) | 2% | WC160 / WI160 |
| Wholesale purchases of motor vehicles, pharmaceuticals, or fuel (not applicable to a computer shop) | 0.5% (RR No. 24-2025, effective Oct. 10, 2025) | — |
A reduced 0.5% rate exists under RR No. 24-2025, but it’s limited to TWA payments to manufacturers or importers of motor vehicles, pharmaceutical products, and solid or liquid fuels sold at wholesale — it has no bearing on a computer hardware distributor, so a TWA computer shop’s bulk laptop or component purchases stay at the standard 1%.
Worked example: one shop, two withholding rates in the same month #
TechPoint Computer Center, classified as a Top Withholding Agent, places two orders in the same month:
- A bulk laptop order from its regular distributor worth ₱500,000. As a TWA goods purchase, TechPoint withholds 1% (₱5,000) and issues BIR Form 2307 using ATC WC158, since the distributor is a corporation.
- A ₱15,000 repair and reformatting job performed by an independent technician it regularly contracts for in-shop repairs, billed separately from any parts used. As a TWA services purchase, TechPoint withholds 2% (₱300) and issues a separate BIR Form 2307 using ATC WI160, since the technician is an individual.
The two certificates carry different ATC codes and rates even though both vendors were paid in the same week — the distinction turns on goods versus services, not on vendor size or relationship.
How BIR Online Tools handles both sides #
A computer shop above the TWA threshold uploads its purchase ledger once, tagging each line as a goods or services purchase; BIR Online Tools’ bulk BIR Form 2307 generator applies the correct 1% or 2% rate and ATC code to each line and produces the certificates for both the distributor and the repair technician from the same batch, rather than requiring the shop to track two separate spreadsheets. The RELIEF and QAP modules then convert the same underlying purchase and sales data into validated DAT files for eSubmission.

Summary #
A computer shop classified as a Top Withholding Agent runs two separate withholding rates on its vendor side: 1% on goods purchased from suppliers under ATC WC158/WI158, and 2% on services like contracted repair labor under ATC WC160/WI160 — never one rate applied to both. Getting the goods/services split right on every vendor avoids an ATC mismatch that can flag a reconciliation issue later.
