Recognizing HDMF's contributions through the years and the need to further strengthen its capability as the biggest source of housing finance in the country to date, President Gloria Macapagal-Arroyo signed into law Republic Act No. 9679 or the Home Development Mutual Fund Law of 2009. The law was signed on 21 July 2009.

Under the new HDMF law, membership to the Pag-IBIG Fund is made mandatory for all SSS- and GSIS-covered employees; uniformed members of the AFP, BFP, BJMP and PNP; as well as Filipinos employed by foreign-based employers. Now more than ever, Filipino workers will enjoy the benefits that are available only to Pag-IBIG members.

Likewise, the law grants the HDMF exemption from tax payments like other government provident institutions. With its tax-exempt status reinstated, Pag-IBIG will have more funds to finance housing and short-term loans as well as investments in government securities. Income from these endeavors is distributed exclusively to Pag-IBIG members in the form of dividends.

The HDMF Law of 2009 also gives the Board of Trustees the authority to set the contribution rates, thereby paving the way for members to save more for their future. Similarly, this will bolster the Fund's resources for home financing.

Pag-IBIG is an acronym which stands for Pagtutulungan sa Kinabukasan: Ikaw, Bangko, Industria at Gobyerno. To this day, the Pag-IBIG Fund continues to harness these four sectors of the society to work together towards providing Fund members with adequate housing through an effective savings scheme.
