Core Viewpoint - The article discusses the implementation of environmental protection tax on construction dust, detailing the calculation methods, tax obligations, and the impact of construction activities on dust emissions [4][5][6]. Tax Obligations - The construction dust environmental protection tax is calculated monthly and reported quarterly, with tax obligations starting from the actual commencement date of the project and ending upon completion [4]. - The tax amount is determined based on the construction area, dust emission coefficients, and any applicable reduction ratios based on regulatory evaluations [5][6]. Calculation Method - The formula for calculating dust emissions is based on the construction area (in square meters), the dust emission coefficient (in kilograms per square meter), and a reduction ratio that varies based on the project's compliance with dust pollution control measures [5][6]. - Specific coefficients for different types of construction projects are provided, such as 0.269 for residential buildings and 0.404 for municipal infrastructure [5]. Case Study - A case study illustrates the tax calculation for a real estate development project, showing how to determine the taxable amount based on the project's area, construction days, and evaluation results [6]. - For example, if a project has a construction area of 10,000 square meters and falls under a second-class evaluation with a 30% reduction, the tax calculation would reflect these parameters [6].
