Indiana contractor license requirements, at a glance
Indiana does not issue one statewide general-contractor license. The state licenses plumbing, while other construction licensing and registration is generally handled by the city or county where the project is located. Start with the Indiana Professional Licensing Agency (IPLA). Confirm the exact credential for your trade, project size, and location before bidding.
Full Indiana licensing detail, local jurisdictions, and official sources
Licensing, bond, and insurance details
| Requirement | Detail | Source |
|---|---|---|
| Surety bond | Indiana has no universal state general-contractor license bond. Cities and counties can require a local contractor bond, and state public-works contracts can require performance and payment bonds. | State source |
| General liability insurance | Indiana sets no universal general-liability minimum for private general contractors at the state level. Local contractor licenses and specific contracts can require insurance. Plumbing and specialized programs must be checked separately for their exact current credential. | State source |

Which Indiana cities will you be working in?
Indiana issues no statewide general-contractor license. Cities and counties register contractors themselves, and plumbing is licensed separately at state level.
A state plumbing license does not register you with a local building department.
Local paperwork is not one thing. These four are separate, and holding one does not give you the others:
- Contractor authorityPermission to hold yourself out and contract for the covered work at all. In these 14 states that permission is granted locally, not by the state.
- Local business licensePermission to operate a business inside that city or county. Separate from contractor authority: having one does not grant the other.
- Tax endorsement or accountA local tax registration or endorsement on a business license. It is a tax obligation, not permission to build.
- Permit accountAn account with the building department that lets you actually pull permits. A city can recognize your credential and still refuse a permit until this account exists.
No jurisdiction in this list matches that filter.
Contractor Lane does not publish a municipal fee, bond, insurance minimum, threshold or exam requirement unless it has been read off that jurisdiction's own current published material and reviewed. Where the status above says an official page only, or not researched, that work has not been done and we will not guess at it. Confirm every local requirement with the jurisdiction before you bid.
How to start a contracting business in Indiana
To start a contracting business in Indiana, set up your business entity, register for the state tax accounts that apply to your work, confirm the contractor credential your trade requires with Indiana Professional Licensing Agency, and clear local permits before you hire or bid. Use the ordered steps below as a planning path and open each official Indiana link to confirm what applies to your entity, trade, project size, and job location.
Choose the business structure
Compare the entity options available in Indiana before you file. Your structure affects registration, taxes, ownership records, and the documents a licensing agency may request.
Register the business
Use the official Indiana filing system to form or register the entity and confirm whether a separate business name filing is needed.
Set up state tax accounts
Check the state revenue agency for business tax registration, sales or marketplace tax rules, withholding, and any industry-specific accounts that apply to your work.
Open the official Indiana Department of Revenue business tax
Confirm the contractor credential
Start with Indiana Professional Licensing Agency. Match the license, registration, classification, or local requirement to the exact trade and scope you plan to sell.

Check permits and local rules
State registration does not replace city, county, building-department, or trade-permit rules. Confirm the job address and scope before bidding or starting work.
Register before hiring
If you will have employees, confirm employer registration, withholding, unemployment, workers compensation, and workplace-safety responsibilities with the responsible agencies.

What to verify before you bid
Before you bid in Indiana, confirm the credential matches the exact work and that your business, tax, and insurance records use the same legal name. A state license or registration does not replace city or county permits, local business licensing, or bond requirements, so verify the job location too.
- Match the credential to the work. General building, residential work, electrical, plumbing, HVAC, roofing, public work, and specialty trades can follow different rules.
- Check the project location. A state registration never replaces city or county contractor registration, permits, bond requirements, or local business licensing.
- Set up the business first when required. Confirm the entity name, tax account, workers' compensation status, and insurance certificate match the name used on the license application and contracts.
- Confirm money and deadlines directly. Fees, financial limits, bonds, insurance minimums, renewal dates, notice rules, and lien deadlines are deliberately omitted unless they were checked against the responsible agency or statute.

Common Indiana contractor startup questions
Does Indiana require a contractor license?
Indiana does not issue one statewide general-contractor license. The state licenses plumbing, while other construction licensing and registration is generally handled by the city or county where the project is located.
Where do I start the contractor application?
Start with Indiana Professional Licensing Agency (IPLA). Confirm the classification and application path for your exact work before relying on a general summary.
