Taxpayer's Charter: Board empowered to adopt and direct administration, granting wide administrative discretion over implementation.
Section 240 obligates the Board to adopt and declare a Taxpayer's Charter and to issue orders, instructions, directions or guidelines to other income-tax authorities for its administration; the Board is not defined here and the phrase "as it considers fit" grants wide administrative discretion. The provision is enabling and administrative in character, lacks Charter content, enforcement mechanisms, timelines and definitions of affected authorities, and the practical effect depends on subsequent instruments implementing the Charter.
