Core Viewpoint - The article discusses the tax policies and risks associated with providing construction services across different administrative regions, emphasizing the importance of proper tax payment and compliance to avoid penalties [3][5]. Tax Policy - Taxpayers providing construction services across counties (cities, districts) must prepay taxes to the tax authority where the service occurs, following the guidelines in the fiscal document [3]. - For services provided within the same administrative region, the temporary measures for tax collection do not apply [3]. Tax Risk Points - Risks arise when taxpayers fail to prepay taxes at the service location upon receiving advance payments, especially when services are provided across different administrative regions [5]. - Taxpayers must clearly understand the timing of tax obligations, which occurs on the day advance payments are received [5]. - The location for tax prepayment must be determined based on whether the service location and the taxpayer's registered location are in the same administrative region [5]. Tax Calculation Methods - General taxpayers should use the general tax calculation method, while those providing services through subcontracting or supply contracts may opt for a simplified method [5][6]. - The prepayment tax calculation for general taxpayers is based on the total price and additional fees, adjusted for subcontracting payments [5][6]. Related Tax Incentives - Small-scale taxpayers with monthly sales not exceeding 100,000 yuan (or quarterly sales not exceeding 300,000 yuan) are exempt from prepayment [8]. - If monthly sales exceed 100,000 yuan, a reduced prepayment rate of 1% applies instead of the standard 3% [8]. Documentation Requirements - Taxpayers must maintain records including contracts with contractors and subcontractors, tax payment ledgers, invoices from subcontractors, and proof of tax payment [8].
