If you’ve recently hired a plumber in Michigan—or are planning to—you might be wondering: Do you pay sales tax to a plumber in Michigan? It’s a common point of confusion for homeowners, especially when invoices include unfamiliar line items. You’re not alone. Many Michigan residents are unsure whether plumbing labor, parts, or emergency repairs are subject to sales tax. In this guide, we’ll cut through the confusion with clear, up-to-date answers based on Michigan’s official tax laws—so you know exactly what to expect (and what to pay).
What Does Michigan Law Say About Sales Tax on Plumbing Services?
Michigan’s sales tax rules hinge on a crucial distinction: labor vs. tangible goods.
According to the Michigan Department of Treasury, pure labor services—like fixing a leaky faucet or unclogging a drain—are generally not subject to sales tax. However, any tangible personal property (e.g., pipes, faucets, water heaters) installed or sold as part of the service is taxable.
💡 Key Insight: If your plumber provides both labor and materials, only the materials portion is taxed—not the time they spend working.
This aligns with broader U.S. tax principles, where services are typically exempt unless explicitly taxed by state law (unlike goods, which are usually taxable). You can learn more about how U.S. states treat service taxation on [Wikipedia’s Sales Tax page](https://en.wikipedia.org/wiki/Sales_taxes_in_the_ United_States).
When Is Sales Tax Applied to Plumbing Work in Michigan?
Not all plumbing jobs are created equal. Here’s when you will likely pay sales tax:
Replacement parts: Faucets, pipes, water softeners, sump pumps, etc.
New installations: Installing a new water heater, garbage disposal, or tankless system.
Emergency repairs requiring materials: If the plumber brings a new valve or seal, that part is taxed.
Conversely, no sales tax applies if:
The plumber only diagnoses an issue (no parts used).
They perform adjustments or cleaning without installing new items.
They unblock a drain using existing tools (no replacement parts).
📌 Example: A plumber charges $150 for labor to fix a running toilet and $50 for a new flapper valve. You’ll pay 6% sales tax (Michigan’s current rate) only on the $50, adding $3 in tax. Total: $203.

Collect and remit the correct sales tax to the state.
If your invoice lumps everything into a single “service fee” with tax applied to the whole amount, that may be non-compliant. Always ask for an itemized breakdown.
⚠️ Red Flag: A plumber charging sales tax on only labor may be misunderstanding the law—or overcharging you.

Common Misconceptions About Sales Tax and Plumbers
Let’s clear up a few myths:
Myth 1: “All contractor services in Michigan include sales tax.” Reality: Only the materials are taxed—not the service itself.
Myth 2: “If it’s an emergency, tax rules change.” Reality: Time of day or urgency doesn’t affect tax status. A midnight pipe repair is taxed the same as a Tuesday morning fix—based only on materials used.
Myth 3: “Plumbers pay the tax, not me.” Reality: You, the customer, pay the tax at point of sale. The plumber acts as a tax collector for the state.

FAQ Section
Q1: Is plumbing labor taxable in Michigan?
A: No. Michigan does not charge sales tax on labor-only plumbing services. Only tangible goods (parts, fixtures) are subject to the 6% sales tax.
Q2: Do I pay sales tax on a new water heater installed by a plumber?
A: Yes. The water heater itself is taxable at 6%. The installation labor is not.
Q3: What if my plumber doesn’t itemize the invoice?
A: Request an itemized receipt. Michigan law expects clear separation of taxable and non-taxable charges. Without it, you can’t verify correct tax application.
Q4: Are sewer line repairs taxed?
A: Only if replacement parts (pipes, seals, etc.) are used. Digging, inspection, or regrading labor is not taxed.
Q5: Can a plumber legally absorb the sales tax instead of charging me?
A: Technically, yes—but it’s rare. Most pass the tax to the customer, as required by law. If they “include tax” in a flat rate, the total must still reflect accurate tax calculation.
