BIR Form 2307 for Shipyards: Withholding on Subcontracted Welding, Riveting, and Drydock Labor

A shipyard that brings in independent welding, sandblasting, painting, or drydock labor crews for a vessel overhaul is paying for a contracted service, and that payment is withheld at the standard 2% general contractor rate under RR No. 2-98 — not at a special maritime rate, and not the same way the shipyard withholds on its own payroll welders. The distinction that matters is the same one this series applies across every trade: whether the worker is the shipyard’s own employee or an independent crew engaged project by project.

This guide is part of the BIR Form 2307 series. For the same contractor rate applied to a different trade, see BIR Form 2307 for Aircon and HVAC Repair and Maintenance Contractors; for the employee-versus-contractor classification test generally, see BIR Form 2307 for Pakyaw (Piece-Rate) Workers: Independent Contractor or Employee?.

Why is drydock labor a contractor payment, not a maritime-specific rate? #

There is no separate BIR withholding category for maritime or drydock work — a welding or riveting crew engaged for a vessel overhaul is a contracted labor service like any other, and falls under the same general contractor bracket this series applies to construction, aircon repair, and ice-plant services. The payor-status test that decides who withholds is the same one applied throughout:

“(A) In general, any juridical person, whether or not engaged in trade or business; (B) An individual, with respect to payments made in connection with his trade or business…”

— RR No. 2-98, Section 2.57.3(A)–(B)

A shipyard organized as a corporation engaging an independent welding crew for a six-week hull repair meets that test under clause (A), regardless of how specialized or maritime-specific the labor itself is — the withholding framework classifies by the nature of the payment (a contracted service), not by industry.

How does this differ from the shipyard’s own payroll crew doing the same work? #

A welder on the shipyard’s own payroll is an employee, covered by withholding tax on compensation computed off the wage tables — a completely different system from the 2% EWT applied to an independent subcontractor performing the identical task. The line isn’t the type of work; it’s who controls it and who bears the business risk of the crew.

A shipyard that treats every drydock-period worker the same way — as either all employees or all subcontractors, without actually checking who controls the work and who’s on whose payroll — risks misclassifying at least one side of this table.

Worked example: a vessel overhaul with mixed labor #

Cavite Shipworks Inc. takes on a six-week hull overhaul for a domestic shipping line. It assigns its own payroll crew to routine maintenance tasks, engages an independent welding subcontractor for structural hull repair, and rents a floating crane from an equipment owner for the heavy-lift portion of the job.

Cavite Shipworks issues BIR Form 2307 to the welding subcontractor for ₱6,400 and to the crane’s equipment owner for ₱7,500, remitting both through its monthly and quarterly withholding returns. Separately, the vessel owner withholds ₱24,000 on its payment to Cavite Shipworks for the overall job and issues the shipyard a BIR Form 2307 for that amount — a certificate Cavite Shipworks then claims as a credit through SAWT.

Frequently asked questions #

Does a shipyard withhold tax on the subcontractors it engages for a vessel overhaul? #

Yes, if those subcontractors are independent crews or businesses rather than the shipyard’s own payroll employees. Welding, sandblasting, painting, and drydock labor crews engaged per project are contracted services under RR No. 2-98, subject to 2% expanded withholding tax, with BIR Form 2307 issued to each.

What rate applies to a welding or riveting subcontractor? #

2% under the general contractor bracket (ATC WC160 for a corporate subcontractor, WI160 for an individually owned crew), the same rate applied to any contracted labor service in this series — there is no separate or elevated rate specific to maritime or drydock work.

Does this differ from how the shipyard withholds on its own payroll employees doing the same kind of work? #

Yes. A welder or rigger on the shipyard’s own payroll is covered by withholding tax on compensation, computed off the wage tables, not expanded withholding tax. The 2% EWT rate applies only to independent subcontractors the shipyard engages as separate businesses or crews, not to its own employees performing identical tasks.

What about equipment rental, like a floating crane or drydock space the shipyard rents from another operator? #

That’s a rental of personal or real property, withheld at the standard 5% rental rate rather than the 2% contractor rate — a shipyard renting a floating crane from an equipment owner for a specific overhaul withholds 5% on that rental fee, separate from any labor subcontracts for the same project.

Does the vessel owner withhold anything when paying the shipyard for the overhaul? #

Generally yes, under the same general contractor rate — the vessel owner withholds 2% on the shipyard’s overall repair bill if the owner is itself a withholding agent, the same as any client paying a contracted repair or construction service, separate from what the shipyard in turn withholds on its own subcontractors.

Summary #

A shipyard’s withholding obligations on a vessel overhaul split along the same employee-versus-contractor and service-versus-rental lines this series applies everywhere else: 2% on independent labor subcontractors, 5% on rented equipment, and ordinary compensation withholding on its own payroll crew — with no separate maritime-specific rate anywhere in the mix.
