Response in English: The purpose of the current US federal income tax system is to raise revenue for the government to fund various public programs and services, as well as to implement policy goals. Individual taxpayers and businesses are required to file annual tax returns, from which their taxable income is determined and their tax liability is calculated. The US federal income tax system is a progressive one, meaning that the tax rate increases as income increases. This structure is in place to ensure that those with higher incomes pay a larger share of their income in taxes, while those with lower incomes pay a smaller share.The tax code also contains many deductions, credits, and other provisions that can reduce taxpayer liability. These provisions are often enacted to achieve policy goals, such as encouraging home ownership, charitable giving, or investment in certain industries.Overall, the US federal income tax system is a critical component of the governments fiscal policy, and it plays an essential role in funding federal programs and services, as well as in shaping economic outcomes. .
