How to Start a Contracting Business in Tucson: The New Contractor Guide
Updated October 2026.
Here's how to start a contracting business in Arizona without learning every lesson the expensive way. This guide walks through the license, the paperwork, the taxes, the books, your prices and your first customers, in the order they actually happen. It's written by Greer, an accountant who has spent nearly 30 years running small businesses and keeping their books.
This guide is general information, not legal or tax advice. Rules and fees change; check the linked sources and talk to a professional about your situation.
Before You Start: Know Your Numbers
Startup costs: tools, truck, insurance, bond, licenses
Write down every cost before your first job: tools and equipment, a reliable truck (and what it costs to insure for work), general liability insurance, your ROC license bond, license and application fees, a phone, software and marketing. Most new owners underestimate this list by a third, mostly on insurance and the things they forgot to write down.
How much cash to hold before your first job
Enough to cover two to three months of business and personal expenses with no income at all. Customers pay late, materials get paid up front, and the first few weeks are slower than you'll plan for. Cash is what lets you say no to a bad job.
Read your market before you buy the truck
Before you spend on equipment, find out who you're up against. Search your trade and your part of town on Google and look at who shows up, how many reviews they have and what they charge. Call two or three for a quote on a common job. You'll learn more about Tucson pricing in an afternoon than in a month of guessing, and you'll know whether you're entering a crowded market or a gap.
Step 1: Get Your Arizona Contractor License
The Arizona contractor license comes from the Registrar of Contractors (ROC). It's usually the longest step, so start here.
Choose your ROC license classification
Arizona licenses contractors by classification: residential, commercial or dual, and by trade. Pick the one that matches the work you'll actually do. Working outside your classification can cost you the job and the license.
Name a qualifying party with four years of experience
Every license needs a qualifying party: a person with at least four years of practical or management experience in the trade, with at least two of those years in the last ten. Accredited technical training can count for up to two of the four years (A.R.S. § 32-1122).
Pass the Statutes and Rules exam and the trade exam
The qualifying party must pass the required exams with at least 70%: the Arizona Statutes and Rules exam, plus a trade exam unless they qualify for a waiver (Arizona ROC).
Post your license bond
The ROC requires proof of a license bond with your application. The amount depends on your classification and expected volume. Keep it active for as long as you hold the license.
How long the license takes
Plan on weeks, not days. Gathering experience documentation and references, scheduling and passing two exams, getting the bond and waiting on the ROC's review all take time, and a missing document sends the application back. Start the license while you're still employed, and use the waiting time to do Steps 2 through 6.
Mistakes that delay an application
- Experience that isn't documented the way the ROC asks for it.
- Applying under the wrong classification for the work you plan to do.
- A business name on the application that doesn't match your registered entity.
- Letting the bond or exam results lapse before the application is complete.
Step 2: Form Your Business
LLC or sole proprietor
Many contractors form an LLC to separate business and personal assets; others start as a sole proprietor because it's simpler. An LLC is registered with the Arizona Corporation Commission. The right answer depends on your risk, your income and your plans to hire, and it affects your taxes as much as your liability. Talk to an accountant or attorney before you file, not after.
Get your EIN
An Employer Identification Number from the IRS is free and takes minutes online. Use it instead of your Social Security number on invoices, W-9s and supplier accounts. You'll need it to open a business bank account and to hire.
Open a business bank account
Running business money through a personal account muddies your books and can weaken the protection your LLC was supposed to give you. Open a business checking account and card on day one, run every job through them, and pay yourself on a schedule.
Insurance before your first job
General liability is the minimum most customers and general contractors will ask to see. A personal auto policy may not cover a work truck, so look at commercial auto. Arizona requires workers' compensation once you have employees. Review coverage with an agent before your first job and again before your first hire.
Step 3: Get Your Arizona TPT License (If You Need One)
Repair work vs. new construction: why it changes your sales tax
Arizona's sales tax is called the Transaction Privilege Tax (TPT), and contractors are treated differently depending on the work. Contractors who do only maintenance, repair, replacement or alteration (MRRA) work generally don't need a TPT license; they pay tax on materials when they buy them. Contractors who do taxable work, such as new construction or major alterations, need a TPT license, and new contractors generally must post a bond with the Arizona Department of Revenue (ADOR contracting guidelines). Classify each job correctly on your invoices: tax you didn't collect becomes tax you owe.
What MRRA looks like in practice
Replacing a water heater, repairing a roof leak, swapping a condenser or rewiring a room in an existing home is generally repair or replacement work. Building an addition, a new home or a major remodel is generally taxable contracting. Many trades do some of both. If you do, you'll likely need the TPT license and you'll need to track which jobs are which. This is exactly where a contractor accountant earns their fee.
Tucson business license
The City of Tucson requires a business license for businesses operating in the city. Much of the 'Tucson' postal area is actually outside city limits, so check your address first. The city's Business Services Department has the application and current fees.
Step 4: Set Up Your Books From Day One
Bookkeeping for contractors isn't about neat spreadsheets. It's about knowing which jobs make money before you take more of them.
Pick an accounting system you'll actually use
The best bookkeeping software is the one you open every week. Look for one that connects to your bank, lets you invoice from your phone, tracks job costs and produces a profit-and-loss statement you can read. Set up your categories once, correctly, and the rest gets easier every month.
Pay yourself on a schedule
Taking money out whenever the account looks full is how owners end up short at tax time. Decide on a regular owner's draw, take it on the same day each month and leave the rest in the business until you know what's committed.
- A separate business bank account and card. Every job runs through it, from the first one.
- Job costing. Track materials, labor and drive time against each job, so you know your real margin.
- Receipts tied to jobs. Snap them as you go; connect your bank to your accounting software.
- Money set aside for taxes. You now pay both halves of Social Security and Medicare (15.3% self-employment tax) plus income tax, and nobody withholds it. Move a percentage of every payment into a tax account.
- Quarterly estimated taxes. Four IRS due dates a year. Put them on your calendar at setup.
Step 5: Price Your Work to Make a Profit
Matching the guy down the street is how new contractors go broke busy. His prices might be built on paid-off equipment, a spouse doing the books for free, or simply on not knowing his numbers either.
Start from your fully loaded cost
Add up what an hour of work really costs you: wages (yours included), payroll taxes, insurance, the truck, fuel, tools you'll replace, your phone and software, and the unbillable hours spent driving, quoting and doing paperwork. Most new owners find their real hourly cost is far higher than the wage they used to earn. Then add materials with a markup, and the profit you need to grow.
Move toward flat-rate pricing
Customers like knowing the number before you start, and flat rates stop you losing money on jobs that run long. Build a price book of your common jobs, review it every quarter and raise prices when your costs go up.
Get paid on time
Unpaid invoices are the most expensive work you'll ever do. Put payment terms in writing before the job starts, take deposits on larger jobs, invoice from your phone the day the work is done and carry a card reader on every truck.
Step 6: Write a Simple Contractor Business Plan
You don't need a 40-page document. You need one page you'll actually look at. A contractor business plan that fits on a page answers six questions:
- Who do you serve, and where? Your trade, your customers and your ZIP codes.
- What do you sell? Your core services and the ones you'll add later.
- What does it cost you? Startup costs and your monthly overhead.
- What do you need to earn? Monthly revenue to cover costs, taxes and your pay.
- How will customers find you? Your website, Google profile, reviews and referral partners.
- What happens in the slow season? Maintenance plans, savings and the work you'll chase.
Review it every quarter. It's less a plan than a promise you keep checking.
Step 7: Get Your First Customers
Google Business Profile and reviews
Set up and verify your Google Business Profile with your service area, hours, photos and services. Then ask every happy customer for a review before you leave the driveway, and text them the link the same day. Reviews are how a new business borrows trust it hasn't had time to earn.
Free and low-cost marketing that works
Nextdoor recommendations, referral partners (realtors, property managers, related trades), yard signs at finished jobs, and before-and-after photos posted every week. None of it is glamorous, and all of it compounds.
Turn one job into three
The cheapest customer to win is one you already have. Offer a maintenance plan or a follow-up visit at the end of every job, leave a magnet or card with your number, and ask who else on the street might need you. A yard sign outside a finished job keeps selling long after you've packed up.
Or start with a site that already rings
A brand-new website can take months to show up on Google. A FOXIFY territory site already ranks for your trade in Tucson, and it carries your name and number from week one, while we help with everything else on this page.
Trade-by-Trade Notes
How to start an HVAC business
You'll need the right ROC classification and, for refrigerant work, EPA Section 608 certification. Equipment costs run higher than most trades: gauges, recovery machine, vacuum pump and a well-stocked truck. Tucson summers bring more calls than one tech can take, so plan for maintenance agreements early; they're what carry you through the mild months. Most HVAC owners say the hardest part of year one isn't the work; it's dispatch, answering every call in July while you're on a roof in 110° heat. Plan who answers the phone before the first heat wave.
How to start a plumbing business
Licensing runs through the ROC by classification, residential or commercial. Expect a big share of your work to come from water heaters, hard-water damage and slab leaks. Invest early in a camera and locator; they win jobs other plumbers have to guess at. Emergency calls pay well but arrive at bad hours, so decide early whether you'll offer after-hours service and what you'll charge for it. Water softener and filtration installs are a steady add-on in a hard-water town.
How to start an electrical business
Your ROC classification determines the work you can take on. Growth in Tucson is in panel upgrades, EV chargers and solar tie-ins. Permits and inspections are a bigger part of the job than in most trades, so build the time into your pricing. Electrical work also draws plenty of homeowner DIY gone wrong, which makes trust and reviews especially valuable. Partnerships with solar installers, realtors and general contractors can keep a new shop's calendar full.
How to start a roofing business
Roofing is seasonal and storm-driven here. Monsoon season can bring a month's work in a week, so line up crews and suppliers before July. Insurance costs are high; get quotes before you set prices. Flat-roof coatings and tile underlayment are steady year-round work. Storm work also brings insurance claims, so learn how adjusters work and document every job with photos. Avoid the trap of hiring fast for one busy month and carrying payroll into a dry one.
How to start a moving company
Moving within Arizona is regulated differently from interstate moves, which need federal (FMCSA/USDOT) registration. Insurance, a reliable truck and dependable labor are your biggest costs. Demand peaks around university move-ins and move-outs and snowbird season. Damage claims and no-show crews are what sink moving companies, so invest in training, written estimates and clear policies. Packing services and senior moves are good margin and good reviews.
How to start a pest control business
Pest control in Arizona isn't licensed by the ROC. Businesses and applicators are licensed through the Arizona Department of Agriculture's Office of Pest Management. Recurring quarterly service is the business model: scorpions, termites and seasonal pests keep customers coming back. Termite inspections for home sales bring steady work from realtors. Price your quarterly plans so the first visit covers its extra time, and build routes by neighborhood to keep drive time down.
When You're Ready to Hire
Your first hire is the moment you go from technician to owner. Do it too early and payroll eats your cash; too late and you burn out turning down work.
Signs it's time
- You're turning down jobs or pushing customers out more than a week.
- You've had three steady months, and enough cash to cover a new wage for at least two more.
- The office work (quotes, invoices, scheduling) is eating your evenings.
What changes when you hire
You'll need to register as an employer, run payroll with tax withholding, carry workers' compensation and keep personnel records. Many first hires aren't technicians at all: a part-time office manager who answers the phone and sends invoices can free up more billable hours than a second tech.
Six Mistakes That Sink First-Year Contractors
- The cash-flow gap. You pay for materials today and get paid in thirty days. Forecast cash a month ahead.
- No reserve. One slow month or broken truck with nothing to fall back on. Save a fixed percentage of every job.
- Underpricing. Matching the competition instead of your own costs. Price from your fully loaded cost.
- Mixed money. Personal and business accounts tangled together. Separate them on day one.
- Lapsed renewals. Your ROC license renews every two years and your bond must stay active. Calendar every date.
- Growing too fast. A second truck before the cash and systems can carry it. Grow when the numbers say so.

Questions New Contractors Ask
How long does it take to start a contracting business in Arizona?
The license is usually the longest step: documenting experience, passing two exams, posting a bond and applying. After that, forming the business, getting an EIN and opening accounts can happen in a few weeks.
Do I need a TPT license as a contractor?
Only if you do taxable work, such as new construction or major alterations. Repair-only contractors usually pay tax on materials when they buy them instead.
Should I form an LLC?
Many contractors do, to separate business and personal assets. Talk to an accountant or attorney about your situation.
How do I get my first customers?
Set up your Google Business Profile, ask every customer for a review and build referral partners. Or start on a FOXIFY site that already takes calls.
What bookkeeping do contractors need?
A separate business bank account, job costing, receipts tied to jobs and money set aside for quarterly taxes, from your very first job.
How much money do I need to start a contracting business?
It depends on your trade. Equipment-heavy trades like HVAC and roofing cost more to start than electrical or pest control. Add up tools, truck, insurance, bond and fees, then hold two to three months of expenses in cash on top of that.
Do I need a business license in Tucson?
If your business operates inside City of Tucson limits, yes. Much of the Tucson postal area is outside the city, so check your address first. Pima County and other towns have their own rules.
