In Texas a plumbing company is a person, and that person is a master plumber

You have been a journeyman for a while. Somebody has told you the master ticket is worth a few dollars an hour. That is the least interesting thing about it.

Texas does not issue a license to a plumbing company. There is no company credential to apply for, no corporate registration with the Texas State Board of Plumbing Examiners, no entity that can hold plumbing authority on its own. Read that as the opening it is. A plumbing business in Texas is a master plumber who has been designated the Responsible Master Plumber of record, and every contract that business signs with the public is signed on the strength of that one person's license. There is no incorporated competitor holding a licence you cannot get, because there is no such licence. There is only whoever holds the ticket.

Which means the master exam is not a pay grade. It is the application form for owning a plumbing company, and it costs $25 to file.

This page is the three ways in, what the exam actually looks like, what the whole thing costs, what the license is worth on somebody else's payroll, and the specific afternoon you stop being on one.

Three ways in, and you are probably already on one

The Board runs the plumbing ladder under Occupations Code Ch.1301, and the master plumber examination application, revised January 2026, qualifies you three ways. Each one is a matter of what is already in your file: a license you hold, a length of time you have held it, a program you already finished. No board interview about your character, no letters of reference, no discretionary route somebody has to grant you.

Read the second row again if you came up through a registered apprenticeship. The Department of Labor program is what cuts the wait to a single year, and the certificate proving you completed it is already in your file. Find the date on it before you count out a second year you may not owe.

Read the third row if you have just moved to Texas. Four years of out of state journeyman time qualifies you for a Texas master license directly. You do not restart at the bottom, and you do not have to work a Texas journeyman year first.

What the exam is, and what the whole thing costs

The master examination is 100 questions, 240 minutes on the clock, 70% to pass. It is open book on the Uniform Plumbing Code with the Texas amendments and on Occupations Code Ch.1301, the chapter this whole page runs on. Four hours for a hundred questions is two and a half minutes each, in books you are allowed to open, on a code you have been building to for years.

It is computer based and delivered at Pearson VUE test centers rather than by the Board itself, which means you book a seat on a date that suits you instead of waiting for a scheduled sitting somewhere three hours away. You pay the $25 to TSBPE to be approved, then the $128.50 to Pearson VUE on the day.

Add the first three and the fifth. Four hundred and fifty three dollars and fifty cents stands between a Texas journeyman plumber and a person who can sign plumbing contracts with the public under a license number of their own. One water heater changeout covers it with money left over.

One piece of timing is worth $225 of that. The RMP application fee falls away if you apply during your renewal period, which opens 90 days before your license expiration date: inside that window you pay the $300 renewal and nothing else. Check your expiry date before you file. It is not a reason to delay a first contract, but if the window is already open it is $225 for reading a date.

What a master on the payroll is actually worth

The Bureau of Labor Statistics counts 44,090 plumbers, pipefitters and steamfitters in Texas as one occupation, May 2025, and does not break them out by license class. So read the spread as the ladder, because that is what it is: one trade, priced by what the person is licensed to sign for.

The median works out at $28.77 an hour and the 90th percentile at $39.37. The national median for the same occupation is $63,800, which puts Texas 6.2% under the country on wages and a long way over it on volume of work, the trade off you already know about.

Now the part a wage table cannot show you. An RMP may act as the RMP of record for only one company at a time. That is the Board's own rule, and it is the whole economics of your license in one sentence.

A plumbing firm in Houston that wants to bid work needs a master who has designated that firm as the RMP company of record. It cannot borrow one from a friend who is already designated somewhere else. It cannot buy one on a monthly basis and split the cost with another shop. It cannot promote a good journeyman into the role this quarter, because that journeyman needs two years of licensed time and a passing exam score first.

Fort Worth prices the same fact on a published schedule. Registration there runs $168.75 a year, and changing the Master or Registered Official on file costs another $60. Dallas charges $30 to change a record. A city holds a named human being against a registered company, and swapping which human that is has a line item.

So the floor under a Texas master's pay is not set by how busy construction is. It is set by the licensing scheme. When you sit down to talk about what you are paid, you are not asking for a raise because you are good at the work. You are the reason the company is allowed to trade.

The designation that turns a license into a company

The master license and the Responsible Master Plumber designation are two different things, and the second one is where the money changes shape.

A master plumber can do master level work, supervise, and pull permits for the company that employs them. A Responsible Master Plumber can contract directly with the public. The RMP is responsible for the general supervision and management of the plumbing work performed under contracts secured under that license, whether the people doing the work are employees or subcontractors. That responsibility is the reason the state hands you the right to sell.

Getting it is a two item list:

Be a master plumber in good standing. You already are, one exam after this page.

Carry $300,000 of commercial general liability insurance. Occupations Code s.1301.552 sets the figure at $300,000 for all claims arising in a one year period, written by an authorized or eligible surplus lines insurer. Section 1301.3576 says the certificate has to be on file with the Board before you begin work as an RMP, so this is a document you sort out first rather than a box you tick later.

For a small plumbing shop that is an ordinary general liability policy from an ordinary broker. It is also the same certificate a general contractor is going to demand before your van comes through the gate, and the same one a city wants attached to your contractor registration, so you are buying one piece of paper that unlocks three doors.

The designation costs $225 to apply for and $300 a year to renew. What it buys is the ability to put your own license number on a proposal, take the deposit into your own account, and keep the margin that currently pays somebody else's overhead.

The application itself, the insurance wording that satisfies the Board, and how to move the designation from your employer's company to yours without a gap in coverage is the Responsible Master Plumber designation.

Six hours a year, and the license keeps earning

Every rung on the TSBPE ladder renews annually, and the continuing education requirement for a master plumber is 6 hours a year. Renewal is $75. One evening, once a year, keeps the credential a business is legally built on.

Then there are the endorsements, which is where a master license starts paying for itself twice. TSBPE issues endorsements in medical gas piping, multipurpose residential fire protection, and water supply protection. Each is a category of work the Board keeps behind its own endorsement, which means the plumber holding one is bidding against a shorter list on hospital, clinic and sprinklered residential jobs. Scarcity you can add to your own license is worth more per hour than any argument about wages.

Compare the maintenance burden across the trades Texas licenses at all: electricians run 4 hours a year through TDLR, air conditioning contractors run 8 hours, and plumbers run 6. Across the rest of construction, framing, carpentry, roofing, painting, concrete, drywall, flooring and landscaping, Texas issues no state license at all, which means no renewal, no classroom hours and no annual fee to keep. That is the deal Texas makes. The trades it regulates, it regulates lightly and renews cheaply. The rest it leaves alone.

Your own shop, in the order it actually happens

The licensing side is done in one afternoon. The company side is a short list, and Texas keeps it short.

Form the entity and get the numbers. A Texas LLC, an EIN, and a franchise tax account. The franchise tax report is due 15 May each year and the no tax due threshold is $2,650,000 in revenue for report years 2026 and 2027, so a shop under that number files the information report and pays nothing.

Put the RMP designation on your own company. One company at a time, so this is the day you resign the designation from your employer and file it on yours.

Register with the cities you pull permits in. Dallas is $120 a year, plus $30 to change a record. Fort Worth is $168.75 a year for a plumbing registration on a one year term. Austin registers you free through its Build and Connect portal. Houston has trade contractors register the state license they already hold. San Antonio runs two year terms at $150 for a home improvement contractor and $170 for a residential building contractor. You register where you work, not where you live.

Bind the general liability policy before you take the first job. The $300,000 the Board wants is the floor, and the gate you actually have to clear is usually written higher. San Antonio asks a registered home improvement contractor for $300,000 per occurrence with $600,000 aggregate and the city named as certificate holder, and a residential building contractor for $500,000 and $1,000,000. Buy for the certificate your customers and your cities ask for rather than the one the statute asks for.

Decide the workers' compensation question on purpose. Texas is the one state where a private employer may elect not to carry it, and the election is a filing rather than a silence: DWC Form-005, between 1 February and 30 April each year, within 30 days of hiring a first employee, and within 10 days of dropping coverage. The choice and what it costs either way is workers' comp is optional in Texas.

Set up the money before the first payment goes wrong. Texas gives plumbing subcontractors real teeth on unpaid invoices, and the teeth are made of dates counted from the 15th of the month. The monthly notice runs to the 15th day of the third month after the month you did the work on commercial jobs, the second month on residential. Payment on a private job is due by day 35, and money that goes past it accrues 1.5% a month. Ten percent statutory retainage sits behind all of it. Track the dates from the first invoice rather than from the first argument, using the Texas lien deadline calculator.

The entity, the EIN, the franchise tax account and the city registrations are the same stack a Texas trade business stands on, and the order to do them in is starting a construction business in Texas. AEC Stack files the incorporation, opens the accounts and holds the insurance certificates on your behalf at start your business.

Running the company on AEC Stack costs nothing monthly. There is no subscription. The platform fee is 2.5% of each invoice processed through the platform, collected on the payment due date, so the business only costs you money in the months it makes you money.

Where you are on the ladder right now

Note what the master row counts. It counts time holding the journeyman license, not additional hours worked. If you licensed as a journeyman two years ago and you have been working since, both gates are already open and the only thing standing between you and a master license is the twenty five dollars and the exam date.

If you are still on the rung below, the hours, the classroom requirement and how that exam is structured are in the Texas journeyman plumber license. If you want the whole ladder on one screen, including where the tradesman rung is worth taking and where it is a detour, that is plumbing licenses in Texas.

Book the exam, then read the Responsible Master Plumber designation so the insurance certificate is already on file the week your license lands. When you are ready to put a company underneath it, start your business does the filings.
