美国打工的税收政策和个人收入如何计算？

在美国打工，每个人都需要支付联邦和州政府的所得税，社会保险税和医疗保险税。但是，税收政策和个人收入如何计算呢？以下将详细说明。

联邦所得税

联邦所得税是指根据联邦政府制定的税收政策，对个人收入进行征收的税金。美国联邦政府根据税收表对不同层次的收入征收不同的税率。根据个人的收入和家庭状况，可以利用税收表来计算联邦所得税。此外，每个人每年都有一定的免税额，可以在计算联邦所得税时减免。

州所得税

州所得税是指根据各州政府制定的税收政策，对个人收入进行征收的税金。不是所有州都征收州所得税，目前只有 43 个州和华盛顿特区征收州所得税。根据各州的税收政策，不同的层次的收入征收不同的税率。

社会保险税和医疗保险税

社会保险税和医疗保险税是指用于支付社会保险福利和医疗保险福利的税金。在美国，雇主和雇员各自分担这些税金。雇主需要向政府缴纳相应的税金，而雇员则需要从工资中扣除相应的税金。社会保险税和医疗保险税的税率是固定的，不受个人收入水平的影响。

If you are working in the United States, it is important to understand the tax policies and how your income is calculated. This blog post will provide a detailed description of the tax policies for workers in the US and how their income is calculated.

Tax Policies in the US

The US tax system is based on a progressive tax structure, which means that the more you earn, the higher your tax rate. There are different tax brackets for different levels of income. The tax brackets are adjusted each year to account for inflation. The current tax brackets for 2021 are as follows:

10% on income up to $9,950
12% on income over $9,950 up to $40,525
22% on income over $40,525 up to $86,375
24% on income over $86,375 up to $164,925
32% on income over $164,925 up to $209,425
35% on income over $209,425 up to $523,600
37% on income over $523,600

In addition to federal income tax, workers in the US also have to pay social security and Medicare taxes. The social security tax rate is 6.2% on income up to $142,800, and the Medicare tax rate is 1.45% on all income. Employers also have to pay a matching amount of social security and Medicare taxes for their employees.

How Income is Calculated

In the US, your income is calculated based on your gross income, which includes all of your earnings before any deductions or taxes are taken out. This includes your salary, wages, tips, bonuses, and any other income you receive. Once your gross income is calculated, deductions and credits are applied to determine your taxable income.

Deductions can include things like contributions to a 401(k) retirement account, health savings account contributions, and charitable donations. Credits can include things like the Earned Income Tax Credit and the Child Tax Credit.

Once your taxable income is determined, your tax liability is calculated based on the tax brackets and rates outlined above. If you have already had taxes withheld from your paycheck, you may receive a refund if your tax liability is less than the amount you have already paid.

Understanding the tax policies and how your income is calculated is important for anyone working in the United States. By knowing how the tax system works, you can make informed decisions about your finances and ensure that you are paying the correct amount of taxes. Key takeaways from this post include:
