"Do I charge tax on labor?" doesn't have a single nationwide answer, it depends on your state, sometimes your trade, and often how you structure the quote itself. Instead of a rate table that goes stale the moment a state updates its rules, here's how to actually find your answer and keep it correct.
This article won't give you a tax rate or a state-by-state table. Sales tax rules change, sometimes mid-year, sometimes by county or city on top of the state rate. A published number here would eventually be wrong and could cost you money either way. Instead, this is a framework for finding and verifying your state's actual current rule yourself, plus how to apply it correctly in your quotes.
Why "is labor taxable" isn't one answer
Every solo contractor runs into this question eventually, usually while writing their first big quote: do I charge sales tax on the labor portion, or just the materials? The honest answer is it depends, and not in a vague, lawyer-being-cautious way. It genuinely varies by state, and within a state it can vary by trade, by job type, and by how the quote itself is structured.
This is exactly why CashWrench's Tax Rate field doesn't come pre-loaded with a number tied to your state. You set it based on your own confirmed answer, and this article is about how to get that answer right, and keep it right as rules change.
The four general categories states fall into
States don't all use the same logic. Most fall into one of four broad approaches. Figuring out which one your state is closest to is the first step before you go looking for the specific rule.
Some states simply tax the full price of a service, labor included, the same way they'd tax a retail sale. If your state takes this approach, the distinction between labor and materials mostly doesn't matter for tax purposes; the whole job is one taxable amount.
This is the simplest category to work with operationally, even though it usually means a higher total tax bill for the customer.
This is a common approach, especially for repair and installation services. The logic: you already paid sales tax when you purchased the materials (or you're expected to), so taxing them again at the point of resale to the customer would be double taxation in some interpretations, while labor is treated as a service, which many states don't tax by default.
If your state works this way, itemizing labor separately from materials on your quote isn't just good practice, it's often the only way to avoid over-taxing the customer.
Some states draw the line based on what you're working on, not what you're charging for. Work performed on real property, something permanently attached to land or a structure, like built-in cabinetry or a repiped bathroom, is often treated differently than work on personal property, like repairing a movable appliance or a piece of furniture.
This category trips up contractors most often because the same trade can cross both lines depending on the specific job. A plumber repairing a fixture attached to the building is doing one thing; a plumber servicing a portable water heater might be doing another, tax-wise, in the same state.
On top of the general state approach, some states carve out specific exemptions for certain trades, certain types of work (like new construction versus repair), or certain customer types (government, nonprofit, resale). These exemptions get added and occasionally repealed over time, they're the most volatile part of the whole picture.
If you work a trade that sits in a gray area, HVAC, flooring, certain electrical work, it's worth checking specifically whether your trade has its own carve-out, rather than assuming the general state rule applies to you.
If you lump labor and materials into one number and your state only taxes materials, you may end up applying tax to the labor portion by accident, overcharging the customer and creating a discrepancy with what you actually owe the state.
The category your state falls into rarely changes. The exact rate and the specific exemptions do. Learn the category once, verify the number every time.
How to find your state's actual current rule
Once you have a rough idea of which category your state likely falls into, confirm it with a primary source. Here's the process that actually works:
Skip forums and general business sites, they're often outdated or written for a different state entirely. Your state's tax authority is the only source that's actually authoritative, and most publish a specific guide for contractors because this exact question generates so much confusion.
Most state tax sites have a dedicated publication, sometimes called a "Tax Bulletin," "Sales Tax Guide for Contractors," or similar, that walks through exactly how labor and materials are treated for trade work specifically. This is usually more reliable than the general sales tax statute, which can be harder to interpret.
Search your specific trade alongside your state and "sales tax exemption" to see if there's a carve-out that applies to you specifically, separate from the general contractor rule.
Most state tax authorities have a phone line for exactly this kind of question, and a five-minute call is worth the certainty. Tax rules are sometimes genuinely ambiguous for edge-case work, and getting a direct answer protects you better than guessing from a published bulletin alone.
Re-check annually, or whenever your state announces a tax law change. The category your state falls into is usually stable for years, but rates, thresholds, and exemptions shift more often than most contractors expect, and local (county or city) rates on top of the state rate can change independently.
Why how you bill the job can change the answer
This is the part contractors most often miss. In several states, the taxability of a job isn't only about whether labor is taxable in the abstract, it's about how you present the charge on the quote and invoice.
| Billing structure | Common tax treatment | What this means for you |
|---|---|---|
| Lump sum (one total, no breakdown) | Sometimes fully taxable | Some states tax the whole amount if labor isn't itemized separately |
| Itemized, labor and materials as separate lines | Often only materials taxed | Itemizing can be the difference between taxing the full job and just the materials |
| Time and materials | Varies, but often follows itemized rule | Keep labor hours and material costs as distinct line items, as CashWrench quotes already do |
This is one of the strongest practical reasons to always itemize your quotes rather than presenting a single bundled number, beyond the trust and transparency benefits, it can directly determine how much tax you're required to collect.
Applying it correctly in your quotes
Once you've confirmed your state's actual rule, here's how that plays out in a CashWrench quote:
If your state taxes everything, set your Default Sales Tax rate in Settings to your confirmed combined rate. It will apply to the subtotal of all line items on every new quote automatically.
If your state only taxes materials, keep labor and materials as separate line items (which CashWrench already encourages by design), and apply tax only where it's actually owed. You may need to calculate the tax manually on the materials subtotal and enter it as a line item rather than using the blanket Tax Rate field, depending on how granular your state's rule is.
If you do tax-exempt work, for nonprofit, government, or resale customers, leave the Tax Rate field blank on that specific quote, overriding your default. Keep documentation of the exemption on file in case it's ever requested.
Once you've verified your state's rule, save it as your Default Sales Tax in CashWrench Settings, it pre-fills the Tax Rate on every new quote automatically, and you can always override it on a specific job. The quote summary shows Subtotal, Tax, and Total as clear separate lines, so your customer always sees exactly what they're being charged and why.
