The principal way for Catholics to support the work of the Archdiocese of Boston is by participation in the annual Catholic Appeal, which launches in the spring of each year. You are invited to make a pledge or a lump-sum gift by means of the material available in the entry-way of the church or the parish office. The Catholic Appeal is to the archdiocese what the weekly collection is to the parish.
The Archbishop of Boston has committed the archdiocese to a high level of financial transparency. In keeping with that promise, the archdiocese publishes an audited financial report after each fiscal year closes on June 30. The report for FY 2012 is now available.
The Archdiocese of Boston has implemented a major change in how people and parishes fund its ministries and administrative services. Commonly used in many other American dioceses, this system relies on a tax on parish income and a binding assessment for the annual Catholic Appeal. Effective on July 1, 2013, the new system considers "base revenue" to comprise contributed parish income plus net income from leased real estate. It imposes a tax of 10% of base revenue on parishes that do not have their own schools, and a binding target of 8% of base revenue for the annual Catholic Appeal. The details, including historical background, rationale, and provisions for abatements, are found in Cardinal Sean's decree and the official instruction that specifies how the tax and assessment are to be implemented.
