Nevada Contractor Requirements at a Glance

This is the short version of what a Nevada contractor actually has to have in place - licence, bond, insurance, tax registration, and the deadlines that come with them - with each item sourced to the statute or agency page that controls it. For the full walkthrough of the registration process itself, see How to Start a Contracting Business in Nevada.

Licence classifications

Nevada's licensing system has three top-level categories. Classification A, General Engineering (subclasses A-1 through A-25), covers large civil work: highways, bridges, dams, excavation, paving, and specialized work like asbestos removal and telecommunication towers. Classification B, General Building (subclasses B-1 through B-7), covers residential and commercial building construction, remodeling, and prefabricated structures. Classification AB is for contractors qualified in both A and B. Within Classification C, Specialty Subcontractors, there are 42 distinct subclassifications, each covering one trade - plumbing, electrical, carpentry, painting, concrete, and so on. The exact scope of work for each C subclassification is set out in Nevada Administrative Code chapter 624, not the statute itself, so check NAC 624 for your specific trade rather than assuming from the classification name alone.

Bond and financial statement

The bond is not a flat number - the Board sets it case by case, from $1,000 to $500,000, based on your licence type, requested monetary limit, financial responsibility, experience, and character, and it has to come from a Nevada-authorized carrier rated A or better (or cash). What you need to submit alongside it scales with how much work you want to bid: a simple software-generated balance sheet is enough at $25,000 or less, but at $1,000,000 and above only a CPA-reviewed or audited statement, done within the past year, qualifies. Swimming pool contractors carry an additional $10,000-$400,000 consumer protection bond on top.

Sales tax - a real conflict in the statute

The state-level sales tax rate is 2%, with counties adding their own rate on top, so the real total is higher everywhere you actually work. On the filing date, Nevada's own statute does not agree with itself: NRS 372.355 states returns are due monthly on the 20th of the following month, while NRS 372.360(1) states a return is due on or before the LAST DAY of the month following the reporting period. Those are two different dates. Confirm which one the Department of Taxation actually assigned your account rather than guessing - and note NRS 372.380 allows periods other than monthly, which is where quarterly and annual filers fit in.

Mechanics lien deadlines

If a customer does not pay, Nevada gives you 90 days after the latest of three events - completion of the work, last delivery of material, or your last day on the job - to record a notice of lien. That window shortens to 40 days if a valid notice of completion has been recorded and served. Residential projects require an additional 15-day preliminary notice before the lien itself goes on record. Once a lien is recorded, you then have 6 months to actually file a lawsuit to enforce it, or it expires - that deadline can be extended by written agreement with the property owner, but never by more than one additional year.

Small-jobs exemption

Repair or maintenance work valued under $1,000 in labor and materials combined does not require a contractor licence, but only if all four conditions hold: no building permit is required, the work is not plumbing, electrical, refrigeration, heating, or air-conditioning, it is not part of a larger project worth $500 or more, and the person doing the work is not a licensed contractor or their employee. Miss any one of those four and the exemption does not apply.

Common questions

How many contractor license classifications does Nevada have?

Three top-level categories: A (General Engineering, subclasses A-1 through A-25, large civil work like highways, bridges and excavation), B (General Building, subclasses B-1 through B-7, residential and commercial building), and AB for contractors qualified in both. Within Classification C, Specialty Subcontractors, there are 42 distinct subclassifications covering individual trades like plumbing, electrical, and concrete.

What is Nevada's sales tax rate and filing deadline?

The state-level rate is 2%, with counties adding their own local rate on top, so the real total is higher than 2% everywhere in the state. On the deadline, Nevada's own statute is not internally consistent: NRS 372.355 states monthly returns are due on the 20th of the following month, while NRS 372.360(1) states a return is due on or before the last day of the month following the reporting period. Confirm the date the Department of Taxation actually assigned to your account rather than assuming either statute controls.

How long do I have to file a mechanics lien in Nevada?

90 days after the latest of: completion of the work, last delivery of material, or your last day of work on the project - or 40 days after a valid notice of completion is recorded and served, if one is used. Once the lien is recorded, you then have 6 months to actually file a lawsuit to enforce it, or it expires. Residential projects also require a 15-day preliminary notice before the lien itself is recorded. Source: NRS 108.226 and 108.233.
