Contractor Startup Costs: Complete Budget Breakdown

Starting a contracting business costs anywhere from a few thousand dollars for a solo tradesperson who already owns tools and a truck to tens of thousands for a general contractor buying equipment and carrying payroll. The fees to get legal are the predictable part: $0 for a state general contractor license in Texas, $540 in Florida state fees for a certified contractor, and $650 in CSLB fees in California plus the premium on a required $25,000 bond. The large and variable costs are tools, a work vehicle, insurance, and the working capital to buy materials and pay workers before customers pay you.

This guide gives the verified government costs, a worksheet for the rest, and how the IRS treats each category. For a state-specific licensing estimate, use the general contractor license cost calculator.

The startup budget, category by category

Licensing, bonds, and registration

A bond's cost is a premium, not the bond amount: a $25,000 bond at a 2% rate costs $500 a year. Details are in contractor license cost by state and how much a contractor bond costs.

Forming the business

An LLC or corporation separates business debts and lawsuits from your personal assets, but it adds filing fees and annual costs:

In California, licensing as an LLC brings extra bond and insurance costs that a sole owner or corporation doesn't face, so compare structures before you file. Whatever you choose, get an EIN and open a separate business bank account on day one.

Insurance

Several states set minimum liability insurance for licensing: Florida general contractors need $300,000 public liability and $50,000 property damage, Washington requires $200,000 bodily injury for multiple persons and $50,000 property damage, and Oregon residential general contractors need $500,000 per occurrence. Commercial clients typically ask for more. Workers' compensation rules vary: Florida covers construction sole proprietors unless an officer exemption applies (the exemption certificate costs $50 for two years), Texas lets most private employers opt out, and California will require every licensed contractor to carry it from January 1, 2028.

Insurance usually requires a down payment of part of the annual premium, then monthly installments, and contractor GL is often adjusted by audit after the year ends. See general liability insurance for contractors and contractor bond vs insurance.

Tools, equipment, and vehicles

This is usually the largest startup cost and the one you have the most control over:

• Start with what you own. Personal tools and a personal truck can be converted to business use; their depreciable basis is the lower of what you paid or their value when you start using them for business.
• Rent specialty equipment until you have steady demand for it.
• Buy used for big-ticket items. Used equipment qualifies for 100% bonus depreciation and Section 179 if it's new to you.
• Subcontract trades you'd rarely perform instead of buying the tools for them.

Working capital: the cost most new contractors underestimate

Working capital is the cash that carries you between paying for a job and getting paid for it. The SBA's startup cost guidance recommends budgeting at least a year of monthly expenses.

Example: one remodel. A $40,000 kitchen remodel with a 30% deposit and the balance due at completion, six weeks out:

You need at least $9,000 of your own cash (or credit) to finish this one job — more if the customer pays late, a change order adds materials, or you run two jobs at once. On commercial work, retainage held until project closeout stretches the gap further; the project closeout guide covers getting it released.

Build a materials cushion into your bids

Material prices can move between the day you bid and the day you buy, especially for imported steel, aluminum, copper, and tools affected by tariffs. Add an escalation clause or a dated price validity window to every estimate, and keep a contingency in your working capital for price jumps. The contractor materials tariff calculator shows how much a tariff change could add to a typical materials list.

Funding options

• Personal savings — the most common source, and the cheapest.
• SBA microloans of up to $50,000 (average about $13,000), generally at 8% to 13% interest with terms up to seven years (SBA microloans).
• SBA 7(a) loans up to $5 million for larger launches or acquisitions.
• Equipment financing secured by the truck or machine.
• SBA Surety Bond Guarantee program if you need bid, performance, or payment bonds and can't qualify on your own — contracts up to $9 million (non-federal), with a 0.6% fee on the contract price for performance and payment bonds (SBA surety bonds).

How startup costs are taxed

The IRS splits early spending into buckets:

• Startup costs (market research, training before launch, pre-opening advertising): deduct up to $5,000 in the year the business begins, reduced dollar for dollar once total startup costs exceed $50,000, and amortize the rest over 180 months (Schedule C instructions).
• Organizational costs for forming a corporation or partnership: a separate $5,000/180-month allowance.
• Tools under $2,500 per item or invoice: expensed under the de minimis safe harbor if you elect it.
• Equipment and trucks: 100% bonus depreciation or Section 179 (up to $2,560,000 for 2026), or regular depreciation — the MACRS depreciation calculator compares them.
• License fees, bond premiums, insurance: ordinary business expenses once you're operating.

Example. Your business starts in April 2026 with $8,000 of startup costs. You deduct $5,000 plus $3,000 ÷ 180 × 9 months = $150, for $5,150 in 2026, then $200 a year ($16.67 a month) after that.

Once you're operating, the contractor tax deductions guide lists what you can write off, and the guide to quarterly estimated taxes explains paying tax on your first profits.

Survival odds

Construction businesses survive slightly better than average. Of construction establishments born in the year ending March 2015, 83.3% were still open after one year, 57.5% after five years, and 42.6% after ten, compared with 79.6%, 50.2%, and 34.7% for all private industries (BLS Business Employment Dynamics). The difference between the businesses that make it and those that don't is rarely skill — it's cash flow and pricing.

Startup checklist

1. Choose your trade and target customers, and check the state and city licensing rules.
2. Compare business structures, including any extra bond or insurance cost for LLCs.
3. Form the entity, get an EIN, and open a business bank account.
4. Get licensed or registered, and file any required bond.
5. Bind general liability, commercial auto, and workers' comp or the applicable exemption.
6. Buy or convert tools and a vehicle; rent what you can.
7. Set up bookkeeping, a mileage log, and job costing from the first job.
8. Build a 12-month cash-flow forecast and line up a credit source before you need it.
