Licensing & taxes for plumbers

Most states license plumbers at journeyman and master levels through documented experience hours and an exam. Reciprocity is limited — fewer states recognize out-of-state plumbing licenses than electrical ones — and a few states license only at the local level.

Whether you charge sales tax on your labor depends on the state and the type of job. Several states tax services by default, and many distinguish a real-property improvement (often not taxed to the customer) from a repair of tangible property (often taxed). This isn't tax advice — confirm with your state revenue department.
