Direct taxes provide only a small portion of governmental revenues, and payments have been in arrears for years. By far the greatest tax sources are the bauxite-related industries. Companies are taxed on the sum of all net profits. The corporate income tax has a flat rate of 38%, and the dividend tax is 25%. All the operating costs of a company are tax deductible, at set rates for certain equipment. The main indirect tax is Suriname's value-added tax (VAT). As of 1 December 2002, the basic rate for goods was raised from 8% to 10%, and the basic rate for services, from 7% to 8%. Staple foods are exempt from VAT.
