INPS, with memorandum no. 168/2010, specified that the new proceeding concerning contributive credits collection – provided for by the article 30 of the Law Decree no. 78/2010 and in force from 1st January 2011 – doesn’t exclude the “friendly charge notice” (so called “avviso bonario”) which continues to be used by the Institute in order to claim the payment of credit amounts, arising from contributive omissions. In fact, INPS will draft and serve the charge notice (so called “avviso di addebito”) – which has validity as executive title – exclusively if the debtor doesn’t pay within the established terms (generally, 30 days).
