Indiana · Licensing Guide
Indiana Contractor License: Complete 2026 City + State Guide
Indiana has no statewide general contractor license. Here is the full map: what the state licenses through the Indiana Plumbing Commission, and what Indianapolis and other cities require for general, electrical, HVAC, and wrecking work on top.
Verified against the Indiana Professional Licensing Agency Plumbing Commission pages, the Indianapolis Department of Business and Neighborhood Services contractor license packets, the Indiana Secretary of State INBiz fee pages, and Indiana Code Title 25, Article 28.5.
- Decide which path applies: a state plumbing license through the Indiana Plumbing Commission, a city contractor license such as Indianapolis general, electrical, HVAC, or wrecking, or both.
- If you self-perform plumbing, apply through the Indiana Plumbing Commission under the Professional Licensing Agency. The tiers run Apprentice, Journeyman Plumber, and Plumbing Contractor, each governed by Indiana Code 25-28.5.
- For general construction, identify each city or county where you will pull permits, because Indiana licenses general contractors locally and the licenses do not transfer between jurisdictions.
- In Indianapolis, pick the license type that matches your work: General Contractor, Electrical, Heating and Cooling, Wrecking, or a registered state Plumbing license.
- For Indianapolis electrical, HVAC, and wrecking, pass the exam and earn approval from the matching license board before submitting the license application.
- Submit a certificate of general liability insurance at the city minimum, a surety bond in the amount the city sets, and workers’ compensation coverage or a valid exemption.
- File each city application, pay the fees, and supply proof of business registration with the Indiana Secretary of State where required.
- Renew on each authority’s cycle: Indianapolis general contractor licenses every 2 years, the Plumbing Contractor license on the Plumbing Commission cycle, and other cities on their own schedules.
What is an Indiana contractor license and who needs one?
An indiana contractor license is not a single credential. Indiana does not issue a statewide general contractor license, so the credential you actually need depends on the trade and the city. At the state level, the Indiana Professional Licensing Agency (PLA) licenses plumbers through the Indiana Plumbing Commission under Indiana Code 25-28.5. Plumbing tiers run Apprentice (registration), Journeyman Plumber, and Plumbing Contractor, with the contractor tier requiring a completed 4-year apprenticeship, a current out-of-state plumbing license, or 4 years of supervised plumbing work, plus a passing exam. General construction, framing, drywall, roofing, electrical, heating and cooling, and wrecking are licensed by each city. In Indianapolis, the Department of Business and Neighborhood Services (BNS) licenses general, electrical, HVAC, and wrecking contractors and requires state-licensed plumbers to register their license with the city. Expect a state filing fee for your business entity, a few hundred dollars per city license, general liability insurance, a surety bond, and workers’ compensation if you employ anyone. A city license clears in a few weeks once your materials are ready, while a Plumbing Contractor license takes years of documented apprenticeship or experience.
Every fact below traces to a primary government source: the Indiana Plumbing Commission licensing pages, the Indianapolis Department of Business and Neighborhood Services contractor license packets, and the Indiana Secretary of State business pages. City ordinances and fee schedules change more often than state statutes, so verify any local figure with the building or licensing department before you pay it.
What Indiana licenses at the state level
There is no Indiana contractor state license board for general construction and no statewide general contractor license application. States like California, Florida, and Arizona run state-level general contractor programs. Indiana does not. The one construction trade Indiana licenses statewide is plumbing, through the Indiana Plumbing Commission inside the Professional Licensing Agency, under Indiana Code 25-28.5.
What this means in practice: a remodeler working in a small Indiana town may face only a local registration, while the same remodeler in Indianapolis needs an Indianapolis BNS license, and in West Lafayette needs a West Lafayette registration and bond. The indiana contractor license you search for most often turns out to be a city-issued license or the state plumbing license that gets mistaken for a general one.
Indianapolis is clear about this split on its own contractor licensing page: for electrical, HVAC, and wrecking contractors, licensing is at the discretion of the local municipality and there is no state license for these trades. For plumbing, licensing is administered by the State of Indiana, and the state license must be registered with the city before plumbing work begins.
What is NOT state-licensed
Indiana does not issue a state general contractor, electrical, HVAC, or wrecking license. Those trades are regulated entirely at the city or county level. A contractor moving into Indiana from a state with a state-level general or electrical license should not assume any state reciprocity exists, because there is no state credential in those trades to reciprocate with. The one related state program is the Indiana Department of Administration public works certification, a prequalification covered later in this guide, not a trade license.
Indiana plumbing license tiers
The Indiana Plumbing Commission runs a clear ladder: registration as an apprentice, the Journeyman Plumber license, and the Plumbing Contractor license, with a temporary contractor license for succession situations. The thresholds and fees below come straight from the commission’s licensing pages.
Plumbing tiers
Indiana plumbers are licensed under Indiana Code 25-28.5 by the Indiana Plumbing Commission. The commission issues Apprentice Plumber, Journeyman Plumber, and Plumbing Contractor licenses, plus a Temporary Plumbing Contractor license.
| License | Requirement | Scope |
|---|---|---|
| Apprentice Plumber | At least 17 years old and enrolled in an approved apprenticeship program | Supervised work that counts toward the Journeyman tier |
| Journeyman Plumber | At least 18, plus a completed 4-year apprenticeship program or a current out-of-state plumbing license; must pass the exam | Full plumbing work under a plumbing contractor |
| Plumbing Contractor | At least 18, plus a completed 4-year apprenticeship, a current out-of-state license, or 4 years of plumbing work under a licensed contractor; must pass the exam | Contracts plumbing work and pulls plumbing permits |
| Temporary Plumbing Contractor | Proof a licensed contractor has died or cannot operate the business | 6-month increments, up to 2 years total, to continue an existing business |
Per the commission, the apprentice must be enrolled in an approved program under the board’s apprenticeship rules, and apprenticeship standards are set in 860 IAC 2-1-1. The Journeyman and Plumbing Contractor candidates must pass a written exam after the commission approves the application. The exam is registered and scheduled through the commission’s testing vendor.
State plumbing license requirements
For the Plumbing Commission, the application stands on four pillars: a qualifying apprenticeship or experience path, a passing written exam, the correct license-tier fee, and the renewal cycle that applies to the tier. Fees are published on the commission’s licensing information page and are set by commission rule, so confirm the current amount before applying.
Experience and apprenticeship
The cleanest route to the Plumbing Contractor license is a completed 4-year apprenticeship in an approved program. Indiana also recognizes a current out-of-state plumbing license, and a third path of 4 years working in a plumbing business under the supervision of a licensed plumbing contractor. The Journeyman tier follows the same apprenticeship-or-out-of-state-license logic, and the apprentice tier is a registration step that must be in place before counting hours.
License fees
The published commission fees are modest compared with the city license stack. Per the licensing information page, the application fees are $10.00 for an Apprentice Plumber, $30.00 for a Journeyman Plumber, $50.00 for a Plumbing Contractor, and $25.00 for a Temporary Plumbing Contractor, with a $50.00 application fee for a Plumbing Corporation that has a responsible licensed plumbing contractor on file. Renewal is $10.00 for apprentices, $30.00 for journeymen, and $100.00 for the Plumbing Contractor and Plumbing Corporation tiers.
The responsible-contractor structure for companies
A plumbing business that operates as a corporation registers as a Plumbing Corporation and must keep a responsible licensed Plumbing Contractor on file. That structure makes the qualified Plumbing Contractor the choke point for most plumbing companies in Indiana, much as a qualifying party works in states that license general contractors at the state level.
How to get an Indiana contractor license: the 8-step process
The steps below capture the common pattern across Indiana cities, with the state plumbing path layered in for contractors who self-perform plumbing work. Most applicants finish a single city license in a few weeks once materials are ready. Exam preparation is the longest variable for the trades that require a board exam.
-
Choose the city or county authority where you will work
Identify every jurisdiction where you plan to pull permits. Indianapolis, West Lafayette, Allen County, and other authorities each issue separate licenses or registrations, and the licenses do not transfer. Contractors working multiple markets hold multiple licenses. If you also self-perform plumbing, plan to apply through the Indiana Plumbing Commission as well.
-
Pick the right license type
Match your work to the city’s categories. In Indianapolis that means General Contractor, Electrical, Heating and Cooling (HVAC), Wrecking, or a registered state Plumbing license. The wrong category either limits your work or pushes you outside your scope, which is a violation either way.
-
Document your business and your qualifier
Register your business with the Indiana Secretary of State if you use anything other than your own surname, and gather proof for the application. For Indianapolis electrical, HVAC, and wrecking, the named individual must pass the board exam and earn approval before the company license application is accepted.
-
Pass the required exam
Indianapolis electrical, HVAC, and wrecking applicants complete an exam and receive approval from the matching license board first. State plumbing applicants pass the Plumbing Commission exam after the commission approves the application. General Contractor licensing in Indianapolis runs through the application packet rather than a board exam, but other cities may add their own test.
-
Bind and document your insurance
Pull a certificate of general liability insurance at the jurisdiction’s minimum. Indianapolis requires a minimum of $500,000 for each occurrence of death or bodily injury and $100,000 for each occurrence of property damage, or $500,000 per occurrence for combined coverage, with the City-County named as additional insured. Add workers’ compensation if you have employees.
-
Post the required surety bond
Most Indiana cities require a license or permit surety bond. Indianapolis requires a $10,000 general contractor bond naming the Consolidated City of Indianapolis and an unknown third party as obligee. West Lafayette requires a $25,000 bond for general contractors and $5,000 per trade for subcontractors. Confirm the amount with the issuing authority before you order the bond.
-
Submit the city application package
Each city has its own form, checklist, and fee schedule. In Indianapolis you email the application, insurance certificate, and bond to the contractor licensing address, then pay the fee through a payment link. Many cities also ask for proof of Secretary of State registration and a workers’ compensation certificate or exemption.
-
Receive the license, attend any orientation, then renew on schedule
Indianapolis general contractor licenses expire December 31 of even-numbered years and renew every 2 years, and new listings must attend an orientation class within 60 days of issuance. The Plumbing Contractor license renews on the Plumbing Commission cycle. Set reminders well ahead of each cycle, because a lapse can stop work in progress.
Exams: state plumbing tests and city trade exams
Indiana has two distinct exam systems: the Plumbing Commission written exam for the state plumbing license, and the city board exams that Indianapolis and other municipalities use for electrical, HVAC, and wrecking work.
State plumbing exam
The Indiana Plumbing Commission requires Journeyman Plumber and Plumbing Contractor applicants to pass a written exam after the commission approves the application. Per the commission, a candidate may attempt the exam up to seven times within a 2-year period following approval, and registration runs through the commission’s testing vendor. Confirm the active code edition referenced on the exam before scheduling.
City trade exams
For Indianapolis electrical, HVAC, and wrecking contractors, the applicant completes an exam and receives approval from the appropriate license board before submitting the company license application. Indianapolis publishes annual board application forms for the Board of Electrical Examiners, the Board of Heating and Cooling Examiners, and the Board of Wrecking Examiners. The Indianapolis General Contractor license uses the application packet rather than a board exam.
Insurance, bonds, and Indiana workers’ compensation
Indiana contractors face three financial-protection requirements that stack: general liability insurance required by each city, a surety bond required by most cities, and workers’ compensation required by state law for businesses with employees.
General liability insurance
Every city that licenses contractors requires a general liability certificate as a condition of licensing. The published minimum varies by jurisdiction. Indianapolis requires a minimum of $500,000 for each occurrence of death or bodily injury and $100,000 for each occurrence of property damage, or $500,000 per occurrence for combined coverage, and the City-County must be named as additional insured as the grantor of the license. Because published figures differ by city, carry one policy with limits high enough to satisfy the highest jurisdiction you work in rather than right-sizing to each minimum.
Surety bonds
Most Indiana cities require a license or permit surety bond, and the amount is set by the city. Indianapolis requires a $10,000 general contractor bond, type-written, naming the Consolidated City of Indianapolis and an unknown third party as obligee, with confirmation of the surety company’s authority to do business in Indiana. West Lafayette requires $25,000 for general contractors and $5,000 per trade for subcontractors. The bond protects the public and the city, not the contractor, so confirm the exact amount and obligee language with the issuing authority before ordering.
Workers’ compensation
Indiana requires employers to carry workers’ compensation insurance, enforced by the Worker’s Compensation Board of Indiana. Indianapolis requires a contractor with employees to carry coverage, and a business with no employees may complete the workers’ compensation waiver on the company license application or provide a clearance certificate from the Worker’s Compensation Board. Corporations, including Sub-S corporations, are required to carry coverage at least for the owner or principal under state law, so plan for it from day one.
City general contractor licensing across Indiana
Because Indiana has no state general contractor license, each city runs its own program. Indianapolis is the largest and the clearest worked example; smaller cities and counties range from a full license to a simple registration backed by a bond. The licenses do not transfer between jurisdictions.
| Jurisdiction | Authority | Renewal | License types |
|---|---|---|---|
| Indianapolis / Marion County | Department of Business and Neighborhood Services | Every 2 years | General, Electrical, HVAC, Wrecking + registered state Plumbing |
| West Lafayette | City permit office | Per city schedule | General contractor + subcontractor registration by trade |
| Allen County (Fort Wayne area) | County contractor licensing | Per county schedule | Contractor licensing by category |
| State public works | Indiana Department of Administration | Per certification cycle | Public works prequalification, not a trade license |
Indianapolis and Marion County
The Department of Business and Neighborhood Services licenses individuals and businesses engaged in construction activity within the Consolidated City of Indianapolis, which excludes the cities of Lawrence, Beech Grove, Speedway, and Southport. BNS issues five license types: General Contractor, Electrical, Heating and Cooling (HVAC), Wrecking, and a registered state Plumbing license. General Contractor licensing under Section 875-101 of the city code requires any person, partnership, or corporation engaging in construction, land alteration, sewer, driveway, or excavation work to be a listed contractor.
The General Contractor license packet sets the requirements: a completed company application, proof of business registration, a certificate of insurance, a $10,000 surety bond, and workers’ compensation coverage or a valid exemption. General Contractor licenses expire December 31 of even-numbered years and renew every 2 years. The license renewal fee is $247.00, and the new-license fee is prorated based on when in the 2-year term you apply. New listings must attend an orientation class within 60 days of issuance. Companies get five authorized agents for free, with a $63.00 fee per additional agent.
West Lafayette
The City of West Lafayette requires bonds on file before a contractor performs any permitted work, and will not issue a building permit until the bond is in place. General contractors must be bonded for $25,000, and subcontractors must be bonded for $5,000 per trade, with each trade listed on the bond. West Lafayette also verifies a General Contractor registration and a state plumbing license for plumbing work, which shows how a smaller city leans on the state plumbing credential while running its own bond program.
Allen County and other jurisdictions
The Allen County contractor licensing program covers the Fort Wayne area and runs its own categories and requirements. Smaller Indiana cities and counties follow one of three patterns: a city-specific license, registration with the county, or simple registration backed by a bond and a certificate of insurance. Call each permit office before submitting a package, because fee schedules and category definitions change.
State public works prequalification
The Indiana Department of Administration runs a Public Works Certification Board. Contractors and subcontractors bidding on state public works projects valued over $150,000 must be prequalified through that board. This is a prequalification to bid on state work, not a statewide contractor license, and it does not replace the city license you need to pull permits for private work.
Setting up your Indiana contractor business
A license, whether city-issued or state plumbing, is one piece of the operational stack. To run as a contracting business you also need a registered Indiana entity, a federal Employer Identification Number, an Indiana tax registration if your work involves selling materials, and a city contractor license in each city where you pull permits.
Choose your business entity
Most Indiana contractors operate as a single-member LLC or an Indiana corporation. The Indiana Secretary of State, through the INBiz portal, charges $100.00 for Articles of Organization to form a domestic LLC. Every business files a biennial Business Entity Report with the Secretary of State to keep active status, filed every other year through INBiz.
Federal EIN and state tax registration
Pull a free Employer Identification Number from the IRS. Register with the Indiana Department of Revenue through INBiz for a sales tax account if your work involves selling materials at retail, and register with the Worker’s Compensation Board once you hire your first employee. Most pure-labor contracts do not collect sales tax, but mixed materials-and-labor contracts may trigger sales tax on the materials portion.
License renewal and continuing requirements
Renewal cycles differ by issuer. Mapping each cycle to a calendar reminder is the cheapest way to avoid a lapse that stops work.
Indianapolis renewal
Indianapolis General Contractor licenses expire December 31 of even-numbered years and renew every 2 years, with a $247.00 renewal fee and a refreshed certificate of insurance, surety bond continuation, and current workers’ compensation documentation at renewal. The bond must carry an expiration date matching the license term, and continuous bonds are not accepted.
State plumbing renewal
Plumbing licenses renew on the Plumbing Commission cycle published on the commission’s renewal pages, with the renewal fee tied to the license tier ($30.00 for journeymen and $100.00 for the Plumbing Contractor and Plumbing Corporation tiers). Confirm your exact expiration date in the PLA online services account, because the apprentice, journeyman, and contractor tiers do not all renew on the same date.
Other city renewal
West Lafayette, Allen County, and other authorities renew on their own schedules and require a refreshed bond and certificate of insurance at renewal. City ordinances change more often than state statutes, so verify current insurance minimums, bond amounts, and fees with the permit office before each renewal.
Reciprocity and common denial reasons
Indiana is not a NASCLA Accredited Examination state for general contractors, because NASCLA reciprocity needs a state-level general contractor license to confer and Indiana does not issue one. Plumbing, by contrast, recognizes a current out-of-state license as a qualifying path.
Plumbing reciprocity
The Indiana Plumbing Commission lists a current out-of-state plumbing license as a qualifying path for the Journeyman Plumber and Plumbing Contractor tiers, alongside the completed 4-year apprenticeship. An out-of-state plumber still files the Indiana application, pays the tier fee, and passes the Indiana exam where the commission requires it, so plan for the exam even when relying on an out-of-state license.
Common denial reasons
- Treating the absence of a state license as the absence of requirements. Indiana’s city-by-city model traps firms that read the missing statewide general contractor license as no regulation. Cities issue stop-work orders against unlicensed contractors and bar future permits until the work is brought into compliance.
- Submitting policy declarations instead of a certificate of insurance. The Indianapolis packet states that policy declarations will not be accepted, the certificate must name the City-County as additional insured, and the business name must match across the application, insurance, and bond exactly.
- A hand-written or continuous surety bond in Indianapolis. Indianapolis requires a type-written bond with the exact obligee language, a matching expiration date, and confirmation of the surety’s authority in Indiana. Continuous bonds and hand-written bonds are rejected.
- A workers’ compensation gap. A missing workers’ compensation certificate or exemption stalls the application. Corporations must carry coverage at least for the owner under state law, and a clearance certificate is required where there are no employees.
- Skipping the city registration for state-licensed plumbing. A state plumbing license alone does not authorize work in Indianapolis. The license must be registered with the city before any plumbing work begins.
Total cost of an Indiana contractor license in 2026
Total first-year cost for a small operation in a single Indiana city is driven by insurance and the surety bond premium rather than license fees, which are modest. The Indianapolis General Contractor renewal is $247.00 and the state plumbing fees run from $10.00 to $100.00 by tier, while general liability insurance and the bond premium are the larger line items. Contractors working multiple cities multiply the application and bond cost by jurisdiction, and contractors with employees add workers’ compensation premiums tied to payroll.
City and state license fees
| Item | Amount | Note |
|---|---|---|
| Indianapolis General Contractor renewal | $247.00 | New license is prorated by application date in the 2-year term |
| Indianapolis additional authorized agent | $63.00 | First five agents are free |
| State Plumbing Contractor application | $50.00 | Renewal $100.00 |
| State Journeyman Plumber application | $30.00 | Renewal $30.00 |
| State Apprentice Plumber application | $10.00 | Renewal $10.00 |
| Other city licenses and bonds | Per current schedule | West Lafayette bond is $25,000 GC / $5,000 per sub trade |
State entity and insurance costs
| Item | Amount | Source |
|---|---|---|
| Indiana LLC Articles of Organization | $100.00 | Indiana Secretary of State (INBiz) |
| Indiana Business Entity Report (biennial) | Set by Secretary of State | Indiana Secretary of State (INBiz) |
| Federal EIN | Free | IRS |
| General liability insurance | Annual premium | Indiana insurance market (Indianapolis minimum $500,000) |
| Surety bond premium | Set by surety and credit | Indianapolis bond amount $10,000 |
Verify current fees with each authority before applying. Indianapolis, the Plumbing Commission, the Secretary of State, and every city update their schedules periodically, and the tables above are a planning reference rather than a substitute for the current published rates.
Common pitfalls to avoid
- Assuming no state general contractor license means no requirements. Indiana’s city-by-city model traps firms that read the absence of a statewide license as the absence of regulation. Indianapolis and most other cities issue stop-work orders against unlicensed contractors and bar future permits until the work is brought into compliance.
- Self-performing plumbing without the state license. A general contractor licensed by Indianapolis is not authorized to self-perform plumbing work. That work goes to a state-licensed plumber who registers with the city, or the firm holds its own Plumbing Contractor license. Unlicensed plumbing work draws administrative penalties.
- Treating one city license as portable. An Indianapolis license does not cover a West Lafayette or Allen County job. Each authority requires a separate application and bond. Indiana cities generally do not have formal reciprocity with each other.
- Mismatched business names across documents. Indianapolis returns packets where the business name does not read exactly the same on the application, certificate of insurance, bond, and workers’ compensation paperwork. Match them character for character.
- Renewing on last year’s ordinance. Cities update bond amounts, fees, and insurance minimums more often than the state updates statutes. Pull the current ordinance and packet from each permit office before every renewal, not just at initial licensing.
Bottom line
Indiana runs one of the most decentralized contractor licensing models in the country: no statewide general contractor license, the Plumbing Commission covering only plumbers at the state level, and every major city running its own contractor program on top. Most firms need a combination, often a city General Contractor license plus, for self-performed plumbing, a state Plumbing Contractor license registered with the city. Plan a few weeks for a city license, years for the state Plumbing Contractor path, and budget for insurance and a surety bond as the largest line items rather than the license fee itself. The biggest risks are not the application but the downstream failures: a workers’ compensation gap, a bond that does not match the city’s exact language, and treating one city’s license as if it works everywhere.

Frequently asked questions about the Indiana contractor license
State vs. local structure
Does Indiana require a general contractor license?
No. Indiana does not issue a statewide general contractor license. The state licenses only plumbing as a construction trade, through the Indiana Plumbing Commission under the Professional Licensing Agency and Indiana Code 25-28.5. General contractor licensing is handled at the city or county level. In Indianapolis the Department of Business and Neighborhood Services issues General Contractor, Electrical, HVAC, and Wrecking licenses, each with its own requirements, bond, insurance minimums, and renewal cycle.
Who issues the Indiana contractor license?
There is no single issuer. The state plumbing license comes from the Indiana Plumbing Commission under the Professional Licensing Agency, authorized in Indiana Code 25-28.5. General, electrical, HVAC, and wrecking licenses are issued by individual cities. In Indianapolis the issuer is the Department of Business and Neighborhood Services, and other cities such as West Lafayette and counties such as Allen County run their own programs.
Cost and timeline
How much does an Indiana contractor license cost in 2026?
Costs vary by city. The Indianapolis General Contractor renewal is $247.00, with a prorated fee for a new license. State plumbing fees run from $10.00 for an apprentice to $50.00 for a new Plumbing Contractor license and $100.00 to renew it. Add a $100.00 Indiana LLC filing, a biennial Business Entity Report, general liability insurance, and a surety bond ($10,000 in Indianapolis). The bond premium and insurance, not the license fee, are usually the largest cost.
How long does it take to get an Indiana contractor license?
For an Indianapolis General Contractor license, plan on a few weeks once your materials are complete: time to bind insurance, post the $10,000 bond, file the application, and pay the fee. The state Plumbing Contractor license takes far longer because it requires a completed 4-year apprenticeship, a current out-of-state license, or 4 years of supervised plumbing experience, plus a passing commission exam.
State trade licenses
Do I need a license to do plumbing work in Indiana?
Yes. Plumbing is the construction trade Indiana licenses statewide, through the Indiana Plumbing Commission under Indiana Code 25-28.5. The tiers run Apprentice Plumber (registration), Journeyman Plumber, and Plumbing Contractor, with the contractor tier requiring a completed 4-year apprenticeship, a current out-of-state license, or 4 years of supervised plumbing work, plus a passing exam. In Indianapolis the state plumbing license must also be registered with the city before plumbing work begins.
Reciprocity and renewal
Does Indiana offer license reciprocity?
For general contractors, no, because Indiana has no state general contractor license to confer and does not participate in NASCLA reciprocity. For plumbing, the Indiana Plumbing Commission recognizes a current out-of-state plumbing license as a qualifying path for the Journeyman and Plumbing Contractor tiers, alongside a completed 4-year apprenticeship. An out-of-state plumber still files the Indiana application, pays the tier fee, and passes the Indiana exam where required.
