The Revenue Department is issuing organic laws, including rules on tax calculation and filing requirements. For example, this law would prevent the Board of Investment from granting certain investment promotions, such as corporate income tax exemptions. The Excise Department's proposal calls for a single excise tax rate, regardless of the retail price. Meanwhile, environmental tax reforms, including the carbon tax, are expected to generate 6 billion baht. In terms of other government revenue, a shift from petroleum concession contracts to production-sharing contracts is expected to generate 71.3 billion baht, with licensing fees adding 12.9 billion baht.
