Jabarkan Budget dari Massachusetts Bay Transportation Authority

Since the "forward funding" reform in 2000, the MBTA is funded primarily through 16% of the state sales tax excluding the meals tax (with minimum dollar amount guarantee), which is set at 6.25% statewide, and therefore equal to 1% of taxable non-meal purchases statewide. The authority is also funded by passenger fares and formula assessments of the cities and towns in its service area (excepting those which are assessed for the MetroWest Regional Transit Authority). Supplemental income is obtained from its paid parking lots, renting space to retail vendors in and around stations, rents from utility companies using MBTA rights of way, selling surplus land and movable property, advertising on vehicles and properties, and federal operating subsidies for special programs.

A May 2019 report found the MBTA had a maintenance backlog of approximately $10 billion, which it hopes to clear by 2032 by increasing spending on capital projects.

The Capital Investment Program is a rolling 5-year plan which programs capital expenses. The draft FY2009-2014 CIP allocates $3,795M, including $879M in projects funded from non-MBTA state sources (required for Clean Air Act compliance), and $299M in projects with one-time federal funding from the American Recovery and Reinvestment Act of 2009. Capital projects are paid for by federal grants, allocations from the general budget of the Commonwealth of Massachusetts (for legal commitments and expansion projects) and MBTA bonds (which are paid off through the operating budget). The FY2014 budget includes $1.422 billion for operating expenses and $443.8M in debt and lease payments.

The FY2010 budget was supplemented by $160 million in sales tax revenue when the statewide rate was raised from 5% to 6.25%, to avoid service cuts or a fare increase in a year when deferred debt payments were coming due.

Capital improvements and planning process

The Boston Metropolitan Planning Organization is responsible for overall regional surface transportation planning. As required by federal law for projects to be eligible for federal funding (except earmarks), the MPO maintains a fiscally constrained 20+ year Regional Transportation Plan for surface transportation expansion, the current edition of which is called Journey to 2030. The required 4-year MPO plan is called the Transportation Improvement Plan.

The MBTA maintains its own 25-year capital planning document, called the Program for Mass Transportation, which is fiscally unconstrained. The agency's 4-year plan is called the Capital Improvement Plan; it is the primary mechanism by which money is actually allocated to capital projects. Major capital spending projects must be approved by the MBTA Board, and except for unexpected needs, are usually included in the initial CIP.

In addition to federal funds programmed through the Boston MPO, and MBTA capital funds derived from fares, sales tax, municipal assessments, and other minor internal sources, the T receives funding from the Commonwealth of Massachusetts for certain projects. The state may fund items in the State Implementation Plan (SIP) – such as the Big Dig mitigation projects – which is the plan required under the Clean Air Act to reduce air pollution. (, all of Massachusetts is designated as a clean air "non-attainment" zone.)
