PL 18-65 Amnesty Information

The Division of Customs Service, Department of Finance announces that Governor Eloy S. Inos signed into law a new amnesty program pursuant to Public Law 18-65

Under the amnesty program, taxpayers may request for the waiver of penalty and interest imposed on delinquent tax liabilities.  A waiver form must be filed to participate in the program.

Unless you are not eligible to participate in the amnesty program, you are encouraged to take advantage of the penalty and interest relief afforded under Public Law 18-65. 

The following are illustrations of some question and answer (Q&A) that can assist you in understanding the amnesty program under Public Law 18-65:

Q1 – Who is not eligible to participate in the program?

A – The tax amnesty program is restricted to people who have not previously "received tax amnesty." A taxpayer who participated in previous tax amnesty programs is considered to have “received amnesty” if a taxpayer applied for and completed all terms associated with the previous tax amnesty.  In this case, a taxpayer is not eligible to participate again in this new amnesty program.  To know more about eligibility, please visit the Division of Customs Service.
