Designation of officers under GST: MVAT officers mapped to GST roles; use respective MVAT or GST titles. Officers who served under the Maharashtra Value Added Tax framework are appointed to corresponding positions for GST purposes by government notification, with a direct mapping of MVAT designations to MGST designations (for example, Commissioner of Sales Tax to Commissioner of State Tax). Officers must use MVAT titles when functioning under the MVAT framework and the corresponding MGST titles when performing duties under the MGST regime.
