If you’re working out how to start a construction business, here’s the short version: decide what work you’ll offer and where, choose a business structure, register the business and its name, get the tax ID numbers you need, check the licenses and permits for your trade and location, open a business bank account and get insured. Then you set up how you’ll price jobs and find your first customers.
The details vary with your trade and your location, so the same checklist leads to different answers for a painter in one state and an electrician in another. This guide gives you the order, the questions to ask, and the official places to get the answers.
This guide is an introduction to what you need to set up and what to pay attention to. It isn’t legal, tax or insurance advice. Before you act on any step, check it with the agencies linked below and talk to the right professional: an accountant, an attorney, the office that licenses your trade, or a licensed insurance agent.
What do you need to start a construction business?
Here’s the whole roadmap on one page. The sections below walk through each step.
| Step | What you decide or get | Where to check |
|---|---|---|
| 1. Define the business | Your services, customers and service area | Your own plan |
| 2. Choose a business structure | Sole proprietorship, LLC, partnership or corporation | SBA, an accountant or attorney |
| 3. Name and register the business | Business name, and a DBA if you use one | Your state’s business registration office |
| 4. Get tax ID numbers | A federal EIN if you need one, and state tax numbers | IRS, your state’s tax agency |
| 5. Check licenses and permits | Trade license, local business license, job permits | The state office that licenses your trade, your city and county |
| 6. Open a business bank account | A separate account for business money | Your bank |
| 7. Get insured | The coverage your work and contracts call for | A licensed insurance agent |
| 8. Set up pricing and estimates | A way to price jobs and a standard estimate | Your own numbers |
| 9. Plan your first customers | Where your first jobs will come from | Your own plan |
The SBA’s Launch your business guide covers most of the same ground for any small business. The steps below add what contractors need on top.
1. Define the business before you register it
Before any paperwork, write down what the business actually does. Every later step depends on it: the license you need depends on the work, the insurance on the risk, and the tax setup on whether you’ll hire.
Answer three questions:
- What work will you do, and what won’t you do? “Interior repainting in occupied homes” is a business. “Painting and anything else that comes up” is too broad to price, insure or license.
- Who is the customer? Homeowners, property managers, general contractors you’d work for as a sub.
- Where will you work? The cities and counties you’ll serve. They decide which local rules apply.
Then finish this sentence: “I help [customer] with [service] in [area].” Keep it. You’ll use it when you talk to the licensing board, the insurance agent and the accountant.
2. Choose a business structure
Your business structure is the legal form of the business. According to the SBA, it affects how much you pay in taxes, your ability to raise money, the paperwork you need to file, and your personal liability.
If you’re starting alone, two structures to compare first are a sole proprietorship and an LLC:
| Sole proprietorship | LLC (limited liability company) | |
|---|---|---|
| Setup | You and the business are the same; often nothing to form | Formed by filing with your state |
| Personal liability | The SBA says you can be held personally liable for the debts and obligations of the business | The SBA says LLCs protect you from personal liability in most instances |
| Paperwork and cost | Often nothing to file if you work under your own name | A filing with your state; ask your state’s business office about fees and yearly requirements |
| Taxes | Depends on your situation | Depends on your situation and the tax treatment you choose |
Partnerships and corporations are the other common options. The SBA page compares all of them.
There is no one right answer for every contractor. The right structure depends on your state, your income, whether you’ll hire, and how much personal risk you’re carrying. That’s a decision to make with an accountant or an attorney. The SBA itself says consulting business counselors, attorneys and accountants can prove helpful.
Example: questions a one-person crew takes to the accountant
A painter who works alone writes these down before the meeting:
- Do I expect to hire anyone in the next year?
- Roughly what do I expect to earn in year one?
- Which of my personal assets would I want protected if a job goes wrong?
- What does my state charge to form and keep an LLC each year?
- How would each structure be taxed for someone in my situation?
- Can I start one way and change later, and what would that involve?
3. Pick a name and register the business
Whether you have to register depends on the structure and the name:
- Working under your own legal name: the SBA says that if you conduct business as yourself using your legal name, you won’t need to register anywhere.
- Using a business name (a DBA, “doing business as”): most states require you to register it.
- Forming an LLC or a corporation: you register it with the state. Most states handle this through the Secretary of State’s office or a state business agency.
Before you settle on a name, check that it isn’t already taken in your state’s business registry.
Registering a business is not the same as being allowed to do the work. Registration creates the business; a contractor or trade license, if your work needs one, is a separate permission from a separate agency. Step 5 covers that.
4. Get your tax ID numbers
The EIN (Employer Identification Number) is your business’s federal tax ID. The SBA lists when a business needs one, including when it:
- pays employees
- operates as a corporation or partnership
- files certain employment or excise tax returns
A sole proprietor with no employees isn’t on that list. The SBA still recommends applying for an EIN right after you register your business, and says it’s free. Ask your accountant what makes sense for you.
If you apply, apply directly with the IRS. The IRS says you never have to pay a fee for an EIN, and it warns about websites that charge for one.
State tax numbers are separate. The SBA says the need for one ties directly to whether your business must pay state taxes, and the process varies by state. Your state’s tax agency or department of revenue will tell you what applies to your work. The IRS’s starting a business page covers the federal side and points you to your state for the rest.
5. Check licenses and permits for your trade and location
This step depends most on your trade and location. The SBA says requirements and fees vary based on your business activities, location and government rules, and it lists construction and plumbing among the activities commonly regulated at the local level.
Keep four things apart, because different offices handle them:
- Business registration - the state record that the business exists (step 3).
- A contractor or trade license - permission to do certain kinds of work. Check with your state’s contractor licensing board if your state has one for your trade, and ask about your specific trade and the size of jobs you’ll take.
- A local business license - some cities and counties require one to operate there.
- Job permits - permission for a specific project, usually from the city or county where the job is. Ask the local building department.
A checklist, this one included, can’t tell you that you’re allowed to do the work. Only the issuing office can. Write down who you spoke to and when.
6. Open a business bank account
Keep business money out of your personal account from the first job. The SBA says to open one as soon as you start accepting or spending money as your business.
Banks usually ask for your EIN (or your Social Security number if you’re a sole proprietor), your formation documents if you formed an LLC or corporation, any ownership agreements, and your business license. Ask your bank what it needs for your structure before you go in. Separating business and personal finances covers the account and the routines that keep it working.
7. Get insured
The SBA describes general liability insurance, which covers claims of injury to other people and damage to their property, as a common type for any business. It also says the federal government requires every business with employees to have workers’ compensation, unemployment and disability insurance, and that laws requiring insurance vary by state.
Which policies you need and how much coverage is right depend on your trade, your state and the work you take. Take your “I help [customer] with [service] in [area]” sentence to a licensed insurance agent. If your trade is licensed in your state, ask the licensing board whether the license requires insurance or a bond.
8. Set up pricing and estimates
Before the first estimate goes out, decide how you’ll get from costs to a price. Two guides to start with:
- Markup vs. margin - how to price a job so it covers your overhead and your own pay, with a worked example for a one-person job.
- How to build a construction estimate - what every estimate needs: scope, exclusions, assumptions, payment terms and a place to sign.
9. Plan where your first jobs will come from
Write down where the first five or ten jobs will come from: people you’ve worked for before, general contractors who know your work, referrals, a basic online presence. Local SEO for contractors covers how to show up when people near you search for your service.
Keep a setup research list
The setup is a list of questions with answers in different offices, so keep the questions in one place. One row per requirement:
| Requirement | Who issues it | Official link | Does it apply to me? | Next action | Status |
|---|---|---|---|---|---|
| Business name (DBA) | State business registration office | (your state’s site) | Yes, using a trade name | File the DBA | Done |
| Contractor license | State contractor licensing board | (board’s site) | Not sure for my trade and job size | Call the board | Waiting |
| EIN | IRS | irs.gov | Not required yet (no employees) | Ask the accountant, then apply online | Open |
| City business license | City clerk or licensing office | (city’s site) | Not sure | Check the city’s site | Open |
The rows above are an example of how to fill it in, not a list of what your business needs. Leave “not sure” as “not sure” until an official source answers it. A row marked done on a guess is the one that causes trouble later.
Your next action
Start your setup research list today. Write your one-sentence business definition at the top, add a row for each of steps 2 to 7, and find the official link for each one in your state, city and county. Then book two conversations: one with an accountant about structure and taxes, and one with your state’s contractor licensing board (or the office that licenses your trade) about your work.
FAQ
Do I need a license to start a construction business?
It depends on your state, your trade, and the size and type of jobs you take. Some work needs a state contractor or trade license, some places require a local business license, and projects may need permits from the city or county. Check with the office that licenses your trade in your state and with the city or county where you’ll work.
Should I start as an LLC or a sole proprietorship?
There’s no answer that fits everyone. According to the SBA, a sole proprietor can be held personally liable for the business’s debts, while an LLC protects you from personal liability in most instances, but an LLC also means state filings and fees. Bring your situation to an accountant or attorney before you choose.
Do I need an EIN if I work alone?
Not always. The SBA lists the cases that require one, such as having employees or operating as a corporation or partnership. If you do apply, it’s free from the IRS, so never pay a website to get one for you. Your accountant can tell you whether you need one.
How much does it cost to start a construction business?
It depends on your trade, your state and the tools you already own. Make a list of one-time costs (registration and licensing fees, tools, a vehicle) and monthly costs (insurance, phone, software, fuel), and get real quotes for each instead of guessing.
In what order should I do the steps?
Define the business first, because every other answer depends on it. Then choose the structure and register, because the bank will ask for both, and the licensing board and insurance agent will want to know what kind of business you are. Licenses, the bank account and insurance come next, before you take paid work.
