Wyoming is one of the easier states to set up and run a trade business. There is no state income tax, and no statewide contractor license for most building work, so your taxes and your paperwork are lighter than in a lot of places. The rules that still bite are the ones that run on a clock: mechanic's liens, permits, and sales tax on the wrong kind of job.
Each section below points to a tool that runs your exact numbers for Wyoming.
Tax in Wyoming
Wyoming has no state income tax, so the only income tax on your trade profit is federal. That means no state return, no state estimated payments, and no state tax to set aside. You still owe federal income tax and self-employment tax and still have to make quarterly federal estimated payments, so do not treat the state tax you are not paying as spare cash.
On sales tax, Wyoming follows the usual rule for the trades: your labor is not taxed, and you pay sales tax on your materials when you buy them rather than charging it to the customer.
Work out what to hold back on the Tax Set-Aside Calculator, which runs the federal and self-employment numbers for Wyoming.
Getting paid: liens and retainage
A mechanic's lien is the tool that actually gets a Wyoming contractor paid, and in Wyoming you generally have to record it within 120 days of the earlier of your last day of work or substantial completion. There is usually an earlier notice to send first, so do not wait until the filing deadline to start. Miss it and you lose the lien, so the dates matter.
Enforcing it has its own clock. 180 days from filing the lien statement. Work out your dates on the Lien Deadline tool, and if they are close, get an attorney to confirm them against the statute (Wyo. Stat. §§29-2-106(a), (c), 29-2-107(a), 29-2-109, 29-2-112(a)).
On money held back as retainage, this is our plain-English summary for Wyoming. 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 Wyoming statute here. Up to 5% is a hedge and not a cap, and the absence of a deadline comes from the same unread summary rather than from reading the statute and finding none.
- Private work: Set by your contract; no clear statutory cap.
- Public work: Up to 5%.
- Release (unconfirmed): No statutory deadline; check the contract.
Heads up: Neither a private cap nor a release deadline is clearly set by statute; both come from your contract.
Check the Retainage Calculator before you sign a contract that holds back more.
There is no Wyoming 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 Wyoming forms below are a different thing: they are the statute's own waiver wording, reproduced, and do not rest on the retainage row.
Free Wyoming lien waiver forms
Wyoming sets out the wording of a lien waiver in its own statute. These are reproduced from it rather than reworded, because the wording is the part that carries the legal effect. What a signature costs you differs from state to state, and not every state makes a waiver that departs from the form unenforceable, so read the notes on the form itself before you sign one.

- Wyoming: Preliminary Notice of Right to Lien, for when you are starting on site, before the lien clock can be relied on
Do you need a license in Wyoming?
Wyoming has no statewide general contractor license, so for most building work there is no state license to get. That is one of the things that makes Wyoming straightforward to start in. It does not mean no rules at all: the state still licenses specific trades like electrical and plumbing, and your city or county can require its own registration or permits, so always check locally before you take a job on.
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
Wyoming 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: none statewide for one- and two-family dwellings; the state's 2024 building and fire codes reach public buildings only
- Electrical: 2026 (effective 1 July 2026, and genuinely statewide with a permit required for essentially all work involving a utility connection)
- Energy: None statewide
- Plumbing: none statewide; no state authority for a plumbing code exists at all
Wyoming runs one genuinely statewide code and it is electrical. A wiring permit and NEC compliance are required almost everywhere for work involving a utility connect or disconnect, enforced by the state itself unless a city or county has taken delegated authority, in which case its standards must be equal or stricter and must keep pace with the state within six months. Everything else is local or absent. The state adopts building and fire codes but only for public buildings, so an ordinary house falls outside them, and there is no statewide residential, energy or plumbing code to fall back on. Before bidding, ring the city or county building department and ask what, if anything, they have adopted.

Pay and workers' comp
The minimum wage in Wyoming is the federal $7.25 an hour. Wyoming's OWN minimum wage is $5.15. DOL states in terms that employers subject to the FLSA must pay the federal $7.25, so the $7.25 shown reaches you only through federal coverage. Employment outside FLSA coverage in Wyoming is legally payable at $5.15. Whether it binds a particular job turns on whether the FLSA reaches that employment, which is the part most people miss. Check a rate on the minimum-wage tool.
On workers' comp, Wyoming is monopolistic: buy directly from the Department of Workforce Services. Rates dropped about 15% for 2026; roofing runs roughly $12 to $25 per $100 of payroll. Get a range on the Workers' Comp Estimator.
If a client will not pay
If a client will not pay, you can sue for up to $6,000 in Wyoming's Circuit Court, Small Claims. 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 Wyoming, with an absolute cutoff 10 years after the job is substantially complete. Work out your exposure on the Warranty & Claim Deadline tool.
Common questions
Does Wyoming have a state income tax?
No. Wyoming has no state income tax, so the only income tax on your trade profit is federal. You still owe federal income tax and self-employment tax and still make quarterly federal estimated payments.
Do I need a contractor's license in Wyoming?
For most general building work, no. Wyoming has no statewide general contractor license. The state still licenses specific trades and your city or county may require its own registration, so check both.
What is the small claims limit in Wyoming?
You can sue for up to $6,000 in Wyoming's Circuit Court, Small Claims. The filing fee is typically $10 to $50. Larger claims go to regular civil court.
Where do I buy workers' comp in Wyoming?
Wyoming is a monopolistic state, so you buy workers' comp directly from Wyoming DWS. Private carriers cannot write it here.
How long do I have to file a mechanic's lien in Wyoming?
Generally 120 days from the earlier of your last day of work or substantial completion, and there is usually an earlier notice to send first. Miss it and you lose the lien. Work your own dates out on the Lien Deadline tool.
Are there free Wyoming contract and payment forms?
Yes. This page links 2 lien waiver forms reproduced from the Wyoming statute rather than reworded. They are free, there is no sign-up, and you fill one in on screen and download it as a PDF or a Word file.
What is the minimum wage in Wyoming?
$7.25 an hour, the federal floor. Wyoming does not set a higher rate of its own, so that floor reaches a worker through federal FLSA coverage rather than through state law. Check a specific job on the minimum-wage tool.
The honest bit
These are the 2026 rules for Wyoming 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 Wyoming tax and licensing agencies, and your local building department) or with a professional. Where Wyoming does something unusual, the detail is called out above rather than glossed over.
