Tap Card Form for Licensed Master Plumbers (Self-Certification)

Currently, all work on domestic service lines that are two inches or less is self-certified. This tap card must be completed by the Licensed Master Plumber authorized to do the work and returned to DEP within 15 days from the permit expiration date. The Tap Card is a requirement of the self-certified permit process and failure to submit this Tap Card may result in the suspension of new permits.
Submit Tap Card Forms electronically via the Permit and Review Information System (PARIS). A tap card web form is available for both online permits and paper permits on PARIS. Please note, all tap cards connected to online permits MUST be submitted online as well. For more information on how to register please visit PARIS.
