CTHRU was launched by the Office of the Comptroller in the fall of 2016 and has quickly become a national model for its depth, breadth, timeliness, and its intuitive experience for exploring how and where our tax dollars are utilized. Stewards of the Commonwealth’s financial data, the Office of the Comptroller is a uniquely independent and apolitical overseer of more than $65 billion in governmental and other funding sources annually. In addition, the Comptroller oversees the Commonwealth’s expenditure and payroll management and major audit functions ensuring security, transparency, accountability, and service delivery across all branches of state government. The powers and obligations of the Comptroller are generally dictated by M.G.L. c.7A.
