Is Electrical & Plumbing Services Subject to PA Sales Tax?

If you’re a homeowner in Pennsylvania hiring an electrician or plumber—or you’re a contractor trying to stay compliant—you’ve probably asked yourself: “Is electrical and plumbing services subject to Pennsylvania sales tax?” You’re not alone. Confusion around service taxation is common, especially since Pennsylvania’s rules differ from many other states. In this guide, we’ll cut through the noise with clear, up-to-date answers based on official state guidance—so you can make informed decisions without risking penalties.

Understanding Pennsylvania Sales Tax Basics

Before diving into electrical and plumbing specifics, it’s essential to grasp how Pennsylvania treats sales tax on services.

Unlike most U.S. states, Pennsylvania does not generally impose sales tax on services. Instead, its 6% state sales tax (plus any local taxes) primarily applies to the sale of tangible personal property—like tools, fixtures, or materials.

However, there are notable exceptions, especially when services involve installation, repair, or maintenance of taxable items. This nuance is where confusion often arises for both contractors and clients.

💡 Key Insight: According to the Pennsylvania Department of Revenue, “Services are not taxable unless specifically listed as taxable by law.”

Are Electrical Services Taxable in Pennsylvania?

Short answer: Generally, no—but materials are.

Electrical work—such as wiring a new home, installing outlets, or upgrading a panel—is considered a non-taxable service in Pennsylvania. However, if the electrician supplies and installs taxable materials (e.g., light fixtures, switches, circuit breakers), those materials are subject to sales tax.

When Does Tax Apply?

📌 Pro Tip: Contractors must clearly separate labor and material charges on invoices. If they don’t, the entire charge may be presumed taxable by auditors.

According to a 2023 audit report from the PA Department of Revenue, over 40% of electrical contractors reviewed had invoicing errors that led to unnecessary tax assessments—often due to poor line-item separation.

Are Plumbing Services Taxable in Pennsylvania?

Same rule applies: labor = not taxable; materials = taxable.

Plumbing services like fixing leaks, installing water heaters, or replacing pipes are not subject to sales tax on the labor portion. But if your plumber provides a new faucet, toilet, water heater, or pipe fittings, those items are tangible personal property and therefore taxable at 6% (plus local rates, if applicable).

Real-World Example:

Sarah hires a plumber to replace her kitchen sink and install a new garbage disposal.

• Labor: $300 → Not taxable
• Sink + disposal (supplied by plumber): $500 → Taxable at 6% ($30)
  Total invoice should show: $800 + $30 tax = $830

Failing to itemize could result in the entire $800 being taxed—a $48 liability instead of $30.

What About Repairs vs. New Construction?

Many wonder if tax rules differ between repair work and new construction. In Pennsylvania, they don’t.

Whether you’re rewiring a 100-year-old Philadelphia rowhome or installing plumbing in a new Pittsburgh condo, the tax treatment remains consistent:

• Labor: Always non-taxable
• Materials supplied by contractor: Always taxable

This uniformity simplifies compliance but requires meticulous recordkeeping.

⚠️ Exception: If a contractor acts as a retailer (e.g., selling a water heater without installation), the full sale is taxable—even without labor.

How Should Contractors Invoice to Stay Compliant?

To avoid audits and penalties, follow these 4 best practices:

1. Separate labor and materials on every invoice.
2. List taxable items individually (e.g., “Delta Faucet Model XYZ – $120”).
3. Charge sales tax only on materials, not the total job cost.
4. Keep receipts for all purchased materials to prove tax was paid upstream (if claiming resale exemption).

Contractors who buy materials tax-free using a PA Resale Certificate (Form REV-1220) must collect and remit tax when those materials are installed for an end-user.

Common Misconceptions Debunked

Let’s clear up frequent myths:

• ❌ Myth: “All home improvement services are taxable in PA.”
  ✅ Truth: Only the materials are taxable—not the service itself.
• ❌ Myth: “If I’m a licensed contractor, I don’t need to charge tax.”
  ✅ Truth: Licensing doesn’t exempt you from sales tax collection on materials.
• ❌ Myth: “Residential jobs are treated differently than commercial.”
  ✅ Truth: The same rules apply regardless of property type.

FAQ Section

Q1: Do I charge sales tax if the customer buys their own materials?

No. If the homeowner purchases materials directly from a store (and pays tax there), your labor-only service is not taxable. Just ensure your invoice reflects labor only.

Q2: Are service calls or diagnostic fees taxable?

No. Diagnostic visits, estimates, or troubleshooting (without parts) are purely labor and not subject to sales tax.

Q3: What about emergency plumbing or electrical work?

Same rules apply. Even urgent after-hours services are non-taxable for labor. Only installed materials incur tax.

Q4: Do local taxes (like in Philadelphia or Allegheny County) change this?

No. While some PA counties add local sales tax (e.g., 1% in Allegheny), the taxability of services vs. materials remains unchanged. Local tax applies only to the same taxable materials.

Q5: Can I include tax in my flat-rate pricing?

You can, but you must disclose it. Pennsylvania requires transparency. A better approach: quote labor + materials + tax separately.

Q6: What happens if I overcharge or undercharge tax?

Overcharging may require refunds to customers. Undercharging can lead to back taxes, interest, and penalties during audits. The PA Department of Revenue typically audits contractors every 3–5 years.

Conclusion

So, is electrical and plumbing services subject to Pennsylvania sales tax? The clear answer is: labor—no; materials—yes. By understanding this distinction and following proper invoicing practices, both homeowners and contractors can avoid costly mistakes and stay compliant.
