Policy Overview - The announcement from the Ministry of Finance and the State Taxation Administration outlines the VAT refund policy for resource comprehensive utilization projects, with refund rates of 30%, 50%, 70%, 90%, and 100% depending on the type of product or service [4]. Compliance Issues - A case study highlights a construction materials company that faced issues due to non-compliance with invoice regulations, resulting in a loss of potential VAT refunds. The company had a sales revenue of 20 million yuan but could not claim refunds for 30% of its raw materials purchased without valid invoices [4]. Tax Refund Calculation - The tax authority emphasized that companies must obtain VAT invoices for recycled resources purchased domestically to qualify for the VAT refund policy. Failure to provide such invoices means that the corresponding sales revenue cannot benefit from the immediate refund policy [4].
