Two things decide whether a job in Arkansas makes you money: getting the license your work needs, and setting aside the right tax. Arkansas 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 Arkansas.
Tax in Arkansas
Arkansas has a graduated state income tax that runs up to 3.7% 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 Arkansas and the IRS through the year.
On sales tax in Arkansas, you follow the usual rule, with labor untaxed and tax paid on your materials at purchase. Ignore the 3.5% contractor's tax you may have heard about; that is a Mississippi rule, not Arkansas. Confirm it for your kind of job before you quote.
Work out what to hold back on the Tax Set-Aside Calculator, which runs the federal and self-employment numbers for Arkansas.
Getting paid: liens and retainage
A mechanic's lien is the tool that actually gets a Arkansas contractor paid, and in Arkansas you generally have to record it within 120 days of your last day of furnishing. Miss it and you lose the lien, so the dates matter.
Enforcing it has its own clock. 15 months from filing the lien - and suing is not enough on its own. Under 18-44-119(b) the lien stops existing after 15 months unless you have BOTH started the action AND filed a lis pendens inside that window. Work out your dates on the Lien Deadline tool, and if they are close, get an attorney to confirm them against the statute (Ark. Code 18-44-114, 18-44-115, 18-44-117, 18-44-119).
On money held back as retainage, here is where Arkansas lands:
- Private work: No statutory cap on private work in Arkansas. Whatever your contract says governs, so read the withholding clause.
- Public work: 5% of each earned progress payment, being the monthly estimate for the portion of work completed.
- Release: Private: no number of days is set at all. It falls due on whatever the contract says. Public: 30 days (the statute does not say whether these are calendar or business days) from the construction contract has been completed.
- Prompt pay: A public authority that has not paid a completed claim within 90 days of it being presented owes 10% a year on the unpaid amount.
Whether the rule covers your job at all is a separate question from the percentage. Public: a public agency, which includes the state, any political subdivision or taxing unit, and any non-profit receiving public funds.
And the step-down is not the same thing as a right. Arkansas cuts the rate to 0% when the contract is 50% complete, the work has been done satisfactorily, and the design professional and the public agency both agree and approve. That drop is not automatic: somebody has to make a finding in your favor first, and reaching the milestone on its own entitles you to nothing. Ask in writing and get the finding recorded. §22-9-604(a)(1)(B)(ii) expressly does not prohibit the agency from withholding retainage throughout the project. Reaching 50% entitles you to nothing on its own.
Heads up: ARDOT and State Highway Commission road work is carved out of the retainage subchapter entirely by §22-9-602, and its 5% comes from ARDOT's own specifications rather than statute.
Check the Retainage Calculator before you sign a contract that holds back more.

Do you need a license in Arkansas?
Arkansas requires a state contractor license to take building work on. The threshold that triggers it: Commercial $50,000 or more; residential above $2,000. Working unlicensed when your job needs a license is the expensive mistake here. Roofing contractors register separately under 17-25-601 et seq. The disaster carve-out at 17-25-103(a)(1)(A)(ii) is a PENALTY-clause carve-out for cleanup within 72 hours of a natural disaster, not a licensing exemption. The license comes from Arkansas Contractors Licensing Board. Arkansas 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
Arkansas adopts its building codes statewide, so the rules travel with you across the state. Editions still move, so confirm yours with the building department before you price a job.
- Homes: 2021 (published as Volume III of the Arkansas Fire Prevention Code, 2021 Edition)
- Electrical: 2020
- Energy: 2009 (published as the 2014 Arkansas Energy Code, with amendments that weaken it below the model text)
- Plumbing: 2018 IPC (published as the 2018 Arkansas Plumbing Code)
Arkansas names its codes by its own edition year in two of the four families, so the number on the state's cover is not the model-code year underneath: the 2014 Arkansas Energy Code is built on the 2009 IECC, and the Arkansas Fire Prevention Code 2021 Edition carries the 2021 IRC as Volume III. Unusually, the building code applies statewide including unincorporated rural areas, so there is no jurisdiction where nothing governs; a local authority may add stricter amendments but may not adopt a different base edition.

Pay and workers' comp
The minimum wage in Arkansas is $11.00 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 Arkansas 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 $5,000 in Arkansas's District Court, Small Claims Division and lawyers are not allowed, which keeps it a level playing field. 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 5 years to sue you over the work under a written contract in Arkansas, with an absolute cutoff 5 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 Arkansas 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 Arkansas tax and licensing agencies, and your local building department) or with a professional. Where Arkansas does something unusual, the detail is called out above rather than glossed over.
