EFIN (Electronic Filing Identification Number)
EFIN (Electronic Filing Identification Number) is a 10-digit identification code issued by Indonesia's Directorate General of Taxes (DJP) to taxpayers, serving as the activation code for electronic tax services including e-Filing, e-Form, and e-Billing on the DJP Online portal. Governed by Regulation of the DJP Director No. 41/PJ/2015 as amended by No. 32/PJ/2017. EFIN is confidential and personal; each taxpayer receives one EFIN for life (while registered active with DJP). To obtain an EFIN, the taxpayer submits a request to the registered Tax Service Office (KPP) in person with photocopies of ID and NPWP card, or through DJP-approved channels such as the Coretax application. EFIN differs from a password: EFIN is the identifier, while a password (PIN/access code) is additional security typically created by the taxpayer on first login.

Example
Budi wants to file his annual return online for the first time. He visits his local tax office (KPP) with photocopies of his ID and NPWP card and applies for an EFIN. After verification, KPP issues Budi's EFIN: 0123456789 (10 digits). Budi then activates this EFIN on DJP Online (djponline.pajak.go.id) and creates his personal password. From then on, he can file his annual return online from home every year without visiting the tax office.
