The government raised about $2.1 billion from taxation, customs and excise in the first half of this year, according to an official report.
The General Department of Taxation announced that it collected $1.192 billion, an increase of 32.14 percent in the first six months of the year, compared with $1.06 billion in the same period last year.
The General Department of Customs and Excise meanwhile collected about $915 million, up 3 percent compared with the same period in 2016.
Taxation General Director Kong Vibol said tax collection increased across all sectors, with income tax rising 32.8 percent, VAT rising 45.1 percent, special taxes increasing by 10.7 percent, and salary taxes increasing by 5 percent.
Finance Minister Aun Pornmonirath told his officials to continue raising awareness on tax duties and procedures among all tax payers, especially those related to real estate.
He also urged officials to strengthen tax collection to ensure efficiency, transparency and accountability, and to encourage small and medium-sized enterprises to register to pay taxes.
He added that officials in customs and excise must strengthen good governance and adhere to strong ethics.
They should also continue to check and review customs and excise tax policy to make it better, especially in the food and beverage industry, he said.
Last month, the Finance Ministry officially launched a single window service to streamline work across several departments. The service is intended to benefit government agencies, private sector firms and the public on issues including tax collection and customs duties. There will be three single window offices within the ministry and three outside.
Those inside will be located in the procurement department, the financial industry department and the national accounting council.
The external services will be at the General Department of Taxation, the General Department of Customs and Excise, and the National Treasury General Department.
