Federal Income Tax

What is a 'Federal Income Tax'

A federal income tax is a tax levied by the United States Internal Revenue Service (IRS) on the annual earnings of individuals, corporations, trusts, and other legal entities. Federal income taxes are applied on all forms of earnings that make up a taxpayer's taxable income, such as employment earnings or capital gains.

BREAKING DOWN 'Federal Income Tax'

Tax is collected from individuals and corporations by the city, state, or country in which the entity resides or operates. When the tax collected is credited to the government of the country’s account, it is referred to as federal tax.

Federal tax is the money used by the government of a country to pay for the growth and upkeep of the country. Look at federal tax as “rent” charged to live in a country or the fee to use the resources provided by a country. When you pay tax to the American government, you’re in effect, investing in your economy as the government uses the funds to build, repair or maintain infrastructure; fund the pensions and benefits of government workers; provide food and housing assistance to the poor; improve sectors such as education, defense, health, agriculture, utilities, public transportation, etc.; embark on new feats such as space exploration; provide emergency disaster relief; etc.

The largest source of revenue for the federal government comes from the income of its residents. When people work for a company, group, or for themselves, they are compensated for the services that they render. They are mostly paid with cash, check, or direct transfer to their bank accounts. Workers receive their earnings either as net income or gross income. Net income is the total amount earned minus federal tax, which means that the company or payer has withheld the tax and paid it to the government on the worker’s behalf. Gross income includes the total amount of income, and the worker would have to pay the government what is owed.

Tax deducted from income is known as the federal income tax. All money earned whether as a wage, a salary, cash gift from employer, business income, tips, gambling income, bonuses, or unemployment compensation constitutes as income for federal tax purposes

The federal income tax is built on a progressive tax system, where higher income earners are taxed at a higher rate. Taxpayers who earn below an annual threshold set by the government would pay little to no tax, while workers who earn six figures or more annually have a mandatory tax rate that applies to their income. The tax rate that applies to each individual is set up in a marginal tax bracket which shows the highest tax rate to be paid on income earned. In effect, the amount of taxable income that one earns determines which tax bracket he would fall into.

As of 2017, the table below shows the seven marginal tax brackets set up by the Internal Revenue Services (IRS) for single or unmarried people.

The marginal tax rate refers to the tax applied on a taxpayer’s next dollar earned. Unless a taxpayer is in the lowest marginal bracket of 10%, s/he would actually have two or more marginal tax brackets. An individual who is unmarried and earns $80,000 annually falls in the 25% marginal tax bracket. This means that:

• the first $9,325 of his income is taxed at 10% for $932.50.
• His next dollar earned falls in the second bracket at 15%. He is taxed at ($37,950 - $9,325) x 15% = $4,293.75.
• His next dollar earned falls in the third and last bracket for him. In this bracket, any income in excess of $37,950 is taxed at 25%. ($80,000 - $37,950) x 25% = $10,512.50.
• His total tax amount to be paid to the government in 2017 is $932.50 + $4,293.75 + $10,512.50 = $15,738.75.

However, note that the tax rate that the individual will end up with is actually 19.67% = $15,378.75 / $80,000, even though his marginal tax rate is 25%. This rate is called the effective tax rate, and is the actual rate that the individual will end up paying the government from his income.

It is important to distinguish between the general notion of income tax and federal income tax. In the United States, governments at the state level may also levy income taxes in addition to federal income taxes. Not all states have implemented state level income taxes. The states of Washington, Texas, Florida, Alaska, Nevada, South Dakota, and Wyoming don’t have income tax. New Hampshire and Tennessee only tax dividends and interest income, and don’t apply taxes to wages, earnings, or other income.
