Value added tax (VAT) accounted for VND55.8 trillion (US$2.53 billion) or 34.87 percent, while collections from imports and exports, special consumption and environment protection duties were VND104 trillion (US$4.72 billion). Another VND200 billion (US$9.09 million) came from other taxes.
The department aims to collect VND237.5 trillion (US$10.79 billion) this year, a year-on-year increase of 20 percent. In efforts to minimise tax fraud, this week the department required its province-level agencies to scrutinise VAT refunds for products exported across the border.
The move was a response to last year's discovery that a number of exporters with VAT tax refunds had a suspiciously sharp rise in both the volume and value of export goods.
Most export products eligible for VAT refunds are in the agriculture, forestry and fishery sectors; the category also includes construction materials and mobile phones.
The department attributed the tax fraud increase to loose regulations on setting up and dissolving firms as well as allowing firms to print invoices on their own.
Loopholes in regulations allowing foreigners to open currency accounts to pay export and import duties in the Vietnamese currency are also frequently exploited.
Last year, the department generated US$9.48 billion in taxes, a drop of 8.8 percent from 2011 that met 88.4 percent of the annual plan.
