Two things decide whether a job in West Virginia makes you money: getting the license your work needs, and setting aside the right tax. West Virginia licenses its contractors and taxes their profit, so both are worth getting right before you take work on.
Each section below points to a tool that runs your exact numbers for West Virginia.
Tax in West Virginia
West Virginia has a graduated state income tax that runs up to 4.58% at the top, on top of your federal taxes. Graduated means the rate climbs as your profit does, so a good year costs proportionally more. You owe federal income tax and self-employment tax as well, and you make estimated payments to both West Virginia and the IRS through the year.
On sales tax, West Virginia is one to read carefully. 6% on construction services by default; exempt only if a 3-criteria capital improvement. Charging tax you should not, or eating tax you should have passed on, comes straight off your margin, so confirm it for your kind of job.
Work out what to hold back on the Tax Set-Aside Calculator, which runs the federal and self-employment numbers for West Virginia.
Getting paid: liens and retainage
A mechanic's lien is the tool that actually gets a West Virginia contractor paid, and in West Virginia you generally have to record it within 100 days of your last day of furnishing. Miss it and you lose the lien, so the dates matter.
Enforcing it has its own clock. 6 months from recording. Work out your dates on the Lien Deadline tool, and if they are close, get an attorney to confirm them against the statute (W. Va. Code §§38-2-8, 38-2-9).
On money held back as retainage, this is our plain-English summary for West Virginia. NOT VERIFIED. No citation on this row at all: it is carried from the June 2026 spine reconciliation and has never been read against a West Virginia statute here. The public 5% and the contract-set release both come from the same unread summary.
- Private work: No statutory cap.
- Public work: 5%.
- Release (unconfirmed): Per the contract.
Heads up: The release timing is set by the contract, not a clear statute; confirm it.
Check the Retainage Calculator before you sign a contract that holds back more.
There is no West Virginia retainage letter on this site, and the NOT VERIFIED line above is why. A letter that tells the party holding your money what to hand over only gets written over a row that has been read against the statute in full. The Document Hub carries the forms that do not turn on a state rule.
Do you need a license in West Virginia?
West Virginia requires a state contractor license to take building work on. The threshold that triggers it: Residential $5,000 or more; commercial $25,000 or more. Working unlicensed when your job needs a license is the expensive mistake here. THE ACT WAS RECODIFIED from Chapter 21 Article 11 into CHAPTER 30 ARTICLE 42; the old 21-11-6 now reads Repealed. 30-42-6 preempts local competency licensing: no municipality, local government or county may require any additional occupational license or other evidence of competence. Pest control operators are exempt unless structural repairs exceed 1,000 on treated property. The license comes from West Virginia Contractor Licensing Board. West Virginia accepts the NASCLA commercial exam, useful if you work across state lines.
Trade licenses for electrical, plumbing and HVAC are usually separate and often required even where a GC license is not. See what applies to your trade on the Contractor License Checker.
Building codes and permits
West Virginia has no single statewide building code, so the edition you build to and whether you need a permit depend on your city or county. Do not assume the town next door adopted the same code or the same amendments.
- Homes: 2018, but only in the counties and municipalities that have voted to adopt it
- Electrical: 2020, on the same opt-in basis
- Energy: 2015 for dwellings / ASHRAE 90.1-2013 for commercial, and the residential code's own energy chapter is deleted
- Plumbing: 2018 IPC, on the same opt-in basis
West Virginia does not run one edition across the whole job, and the energy code is where it splits: 2015 for dwellings / ASHRAE 90.1-2013 for commercial, and the residential code's own energy chapter is deleted. That matters more than the number itself. If you work on houses, the residential edition is your book, and the single figure quoted in most adoption charts is the commercial one.
West Virginia has a State Building Code but it is not statewide law. It takes effect only in a county or municipality that votes to adopt it and then notifies the Fire Commission, and by the most recent count that is nine counties and 51 cities and towns. Everywhere else no building code is enforced at all and there is no state fallback behind it, so the first question here is whether your jurisdiction has adopted anything. A jurisdiction that adopts may also decline the property maintenance code specifically and may amend discretionary provisions locally. One thing to diary: the whole rule expires on 1 August 2027 unless the Fire Commission renews or replaces it.

Pay and workers' comp
The minimum wage in West Virginia is $8.75 an hour. That is the floor for anyone you put on the books, and it is worth confirming against the state labor department each year because several states step their rate mid-year. Check a rate on the minimum-wage tool.
Workers' comp rates in West Virginia are not published as a single figure; they turn on your trade's class code and your payroll. Get a realistic range on the Workers' Comp Estimator, then get a real quote.
If a client will not pay
If a client will not pay, you can sue for up to $20,000 in West Virginia's Magistrate Court. That covers most unpaid-invoice disputes for a small outfit; a bigger claim goes to regular civil court where you will probably want an attorney. Walk through whether filing is worth it on the Small Claims checker.
The clock runs the other way too: a client generally has 10 years to sue you over the work under a written contract in West Virginia, with an absolute cutoff 10 years after the job is substantially complete. Work out your exposure on the Warranty & Claim Deadline tool.

The honest bit
These are the 2026 rules for West Virginia as they stood when this guide was written, and they change: legislatures move thresholds, deadlines and rates every year. Treat this as general guidance to point you in the right direction, not legal, tax or financial advice. Verify anything you rely on at the source (the IRS, the West Virginia tax and licensing agencies, and your local building department) or with a professional. Where West Virginia does something unusual, the detail is called out above rather than glossed over.
