People in United States are liable to pay a part of their income to federal, state or local governments as an income tax. The calculation of the income tax depends upon the taxable income slabs and the rate of interest for every slab which is pre-defined according to the tax laws.
In a broader environment, individuals, corporations, trusts and other organizations operating under the jurisdiction of the US government are directly taxable according to the laws.
The citizens of United States and residents living in the country have to pay taxes on the worldwide income they earn. Whereas, non-resident citizens are supposed to pay the income tax only on the income they earn in United States if any. The income tax norms for trusts and organizations imply that these entities are taxable only on the income which remains undistributed. Also, there is a different practice followed for collection of taxes in case of partnerships. If a business entity is being operated as a partnership firm, the entity is not directly taxable. Instead, all the partners involved in the partnership are individually taxed for the share of income earned.
The taxable income is the amount which remains after subtracting the allowed deductions from the total income earned within a year. In case of companies and business organizations, most of the expenses made for business purposes are termed to be deductible. Similarly, some personal expenses such as state taxes, home mortgage interest and money given away in charity are tax deductible. Another important aspect to be considered in income tax is the capital gains. The amount earned by an individual or business as a profit on investments such as stocks, bonds or property is completely taxable under the law.
The income tax is generally self-assessed by the taxpayer and then the tax return is filed. Advance tax payments if made any are required to be in the form of estimated payments or withholding tax. The determination of income tax is done separately by every jurisdiction within the country which imposes tax. The due date to pay the tax amount and administrative procedures regarding filing and payment of taxes can vary from jurisdiction to jurisdiction. The due date for the payment of Federal taxes by individuals is April 15, which is also the due date followed by many other state and local governments.
