The Internal Revenue Service (IRS) collects the federal income tax in the United States on behalf of all individuals, businesses, trusts, and other legal entities. All sources of income that contribute to a taxpayer’s taxable income, such as wages, salaries, commissions, bonuses, tips, investment income, and certain categories of unearned income, are subject to federal income taxes.
Individual federal income tax rates in the US are progressive, which means that they rise in proportion to taxable income. Federal income tax rates range from 10% to 37%, and they become effective at a certain level of income. Tax brackets are the ranges of income to which the rates are applied. Each tax bracket has a different rate of taxation that applies to certain types of income.
- The U.S. government’s main source of income is the federal income tax.
- The federal income tax is used for a variety of costs, including constructing and maintaining the nation’s infrastructure, enhancing public education and transportation, and offering disaster relief.
- Everyone is subject to federal income taxes, which are determined by your income and filing status and are imposed regardless of where you reside or work.
- Tax deductions and tax credits, which are provisions of law that favor particular categories of taxpayers, can be used to lower the federal income tax obligation.
- State income taxes are gathered by the specific state(s) in which a taxpayer resides and makes a living, as opposed to federal income taxes, which are collected by the federal government.
Federal Income Tax Procedures
The city, state, or nation where they reside or conduct business is responsible for collecting tax from both individuals and businesses. Federal taxes are those that are collected and paid to the federal government of the nation.
Federal taxes are used by governments to fund the expansion and maintenance of the nation. Some people consider federal taxes to be the “rent” they must pay in order to reside in a nation or to use its resources. Taxes are an investment in the American economy because the government utilizes the money for the following purposes:
- Infrastructure should be constructed, repaired, and maintained. Government employee pensions and benefits should be funded. Social Security programs provide funding for important health initiatives including Medicare, Medicaid, CHIP, and market subsidies provide funding for “safety net” initiatives to help low-income households.
- Funding for international security and defense initiatives
- Boost industries including agriculture, utilities, public transit, public health, and education.
- Take on new challenges, like space exploration
- Immediately assist in disaster assistance
The United States’ fiscal year 2023 had $1.4 trillion in income and $1.93 trillion in spending, leaving a $460 billion deficit.
The income of its citizens is the federal government’s main source of funding.
The IRS received almost to $4.1 trillion in revenue in 2021 (the most recent year for which data is available), $2.3 trillion of which came from people, estates, and trusts. Taxes on corporate revenue totaled $419 billion during the same time.
Taxable Income Categories

Taxable income comes in many forms. Also, various sources of income may be taxed at various rates. Earned income and unearned income are the two main categories of income.
Earned income is money that you receive largely as a result of working for an employer, whether you are an independent contractor or not. The most typical ways that people generate money are:
- Pay, whether it be a salary or an hourly rate
- Revenue from activities or from a business
- Pensions as well as other retirement benefits
- Unemployment compensation
- Sick leave and other fringe perks
- Income from self-employment
Unearned income is money that is mostly produced through more passive activities, particularly those related to investment. Unearned revenue generally comes in the following forms:
- Dividends or interest revenue
- Royalties or recurring revenue
- Staking bonuses or bitcoin airdrops
- Asset sales that generate profits
Comparing gross and net income
Either net income (NI), usually referred to as take-home pay, or gross income is given to employees. Net income is the entire amount received after withholding for taxes, benefits, and voluntarily made donations. When taxes are withheld, it indicates that the employer or payer has compensated the government for the employee’s tax.
Your income and the details you provided on Form W-4 determine how much your employer withholds for taxes. For federal tax purposes, every dollar earned counts as income, including wages, salaries, monetary gifts from employers, company revenue, gratuities, winnings from gaming, bonuses, and unemployment benefits.
submitting federal tax returns
Via a number of forms developed by the U.S. Department of Treasury, federal income taxes are recorded and sent to the IRS. Form 1040, which is the main form used to record Federal income taxes, collects not only your personal data but also details about your earnings and tax-saving actions for the year.
A taxpayer often attaches or provides additional forms if they have more information to offer to the IRS. For instance, you must submit Schedule A to support your return if you want to claim an itemized deduction).
Workings of Tax Brackets
The United States has a progressive tax system, which means that as income increases, people must pay an increasing amount of tax. This method tries to give lower-income persons built-in tax advantages while increasing tax revenue from higher-income individuals.
Tax brackets are frequently used to describe a range of income with a corresponding percentage. For example, taxpayers who earn between $44,726 and $95,375 are “in the 22% tax bracket” for the 2023 federal income tax year.
This indicates that a 22% tax rate will be applied to their profits between these two sums. Earnings are taxed at a lesser rate if they are less than $44,726 and at a higher rate if they are more than $95,375.
Comparing the marginal and effective tax rates
For instance, a single person with an annual income of $80,000 is subject to a 22% marginal tax rate.
A taxpayer’s effective tax rate will often be lower than their highest tax bracket because of the many tax brackets. The additional tax paid for each additional dollar of income is known as the marginal tax rate. A 10% marginal tax rate, for instance, indicates that $.10 of each subsequent $1 earned will be collected as tax.
The effective tax rate is 16.1%, despite the marginal rate being 22%. This amount is calculated by multiplying the entire tax obligation ($12,908) by the income ($80,000) and dividing the result by 100. The real tax rate that a person ultimately pays to the government is known as the effective tax rate.
Tax deductions

Making less money or obtaining greater tax benefits are the two methods to reduce your tax burden. There are various particular locations people may look for tax benefits since it is often more profitable to do so.
Legislative provisions known as tax deductions enable taxpayers to lower the amount of income that is taxed on their return. Tax deductions reduce the computation basis for the taxpayer’s tax liability even when they don’t directly lower the amount of tax that must be paid.
Take a taxpayer who makes contributions to a standard IRA as an illustration. The taxpayer is frequently permitted to deduct their donation from their taxable income. The taxpayer’s taxable income would have been lowered by $6,500 if they had made the maximum contribution allowed for 2023. This might save the taxpayer $1,430 in taxes ($6,500 * 22%) if they are in the 22% marginal tax rate.
Illustrations of Tax Deductions
The standard deduction is the federal tax deduction that is most frequently utilized to lower your federal income tax obligation. Depending on their filing status, every taxpayer is eligible to claim a standard deduction. With this amount—which is evaluated every year—taxpayers can lower their taxable income by a predetermined, federally regulated amount.
The itemized deduction is an alternative to the standard deduction. This choice enables taxpayers to accumulate specific kinds of permitted costs and choose to write off the full amount of those costs rather than the standard deduction. These kinds of costs include philanthropic donations, mortgage interest payments, and healthcare costs.
The deductions that are not included in the standard deduction or itemized deduction come last. For instance, many forms of retirement contributions may be written off as long as taxpayers achieve particular contribution and income levels. As an alternative, taxpayers may be eligible for deductions on certain kinds of expenses, such educational costs.
Tax Credits as a Means of Decreased Taxation
Legislative provisions known as tax credits enable a taxpayer to lower their tax liability. Following the determination of a taxpayer’s tax due, the taxpayer may then immediately decrease that liability by the tax credit amounts for which they are qualified.
Consider a taxpayer who qualifies for the Child Tax Credit and has a single child. Taxable income for the taxpayer is $50,000, and their tax obligation is $4,500. The tax obligation is directly decreased by the Child Tax Credit from $4,500 to $2,900. The Child Tax Credit is applied straight to the tax payable amount rather than to the $50,000 of taxable income.
The highest tax credits are all connected to efforts to enact legislative incentives for particular categories of taxpayers. For instance, the American Opportunity Tax Credit and Lifetime Learning Credit provide tax credits to people who are seeking higher education, while the Earned Income Tax Credit provides tax credits to low-income people. Those who have children or dependents benefit from the Child and Dependent Care Credit.
Tax Credits: Refundable vs. Nonrefundable
Certain federal tax credits are nonrefundable, which means that after they have reduced your tax burden to zero, you could not be eligible for further benefits or a refund for any leftover credit. The Adoption Tax Credit is one example of a nonrefundable tax credit; once the credit reduces a taxpayer’s tax burden to $0, the individual will just stop paying tax.
However, certain credits may be refundable. Refundable tax credits not only allow a taxpayer to have no tax responsibility at all, but they can also result in a tax refund for the taxpayer. For instance, you would finally get a $250 tax refund if you owe $750 in taxes but are eligible for a $1,000 refundable tax credit.
Be aware that certain credits only have a limited return policy. For instance, the $2,000 Child Tax Credit is partially refundable; in 2023, it will be up to $1,600.
Federal income tax against state income tax
It’s critical to distinguish between federal income tax and the concept of income tax. In the United States, in addition to federal income taxes, state governments may also impose income taxes.
State-level income taxes are not present in every state. Presently, there is no income tax in Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Only dividends and interest income are subject to taxation in New Hampshire, but these levies will be eliminated entirely by 2027.
Federal Income Taxes: Individuals vs. Other Income Taxes
The material presented here has mostly been educational in terms of personal federal income taxes. Some organizations also pay taxes to the IRS.
Companies are subject to the same tax reporting requirements and advantages as individuals. The tax filing deadline for some types of legal businesses, such partnerships, is different from the deadline for individual taxpayers.
Businesses are also eligible for a variety of tax credits that are uniquely offered to companies; many of these benefits come from the General Business Credit reported on Form 3800.
In order to keep their tax-exempt status, charities and nonprofits that have been granted it frequently complete a Form 990 with the IRS. The nonprofit does not owe any taxes as a consequence of this information report. The tax-advantaged status might be suspended or further evaluated as a consequence of information submitted on the return, nevertheless.
Finally, it’s possible that foreign persons or companies will need to submit federal taxes in the United States. Foreign entities with income-generating operations inside the United States are subject to different regulations than domestic firms with operations outside the country.
Which Federal Income Tax Rates Apply in 2022 and 2023?
Based on an individual’s income and filing status, the federal income tax in the United States is a marginal tax rate structure. The tax brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37% for the 2022 and 2023 tax years.
Is Social Security Income Considered?
Benefits from Social Security are not included in gross income. Benefits are nevertheless a part of your total income, which the IRS considers to decide whether you must pay taxes on your benefits. Your adjusted gross income (AGI), nontaxable interest, and half of your Social Security payments are added together to establish your combined income. You might be taxed on up to 50% of your benefits if your total annual income is between $25,000 and $34,000. You can be taxed on up to 85% of your benefits if your total income exceeds $34,000.
Which nation imposes the highest federal income tax rates?
At a 60% tax rate, the Ivory Coast has the highest rate. Sweden (52.3%), Aruba (52%), Belgium (50%), Israel (50%), Finland (56.95%), Denmark (56), Japan (55.97%), Austria (55), Belgium (50%), Israel (50%), and the Netherlands (49.5%) make up the top 10.
Who Enacted the First Federal Income Tax in the United States?
By signing the Revenue Act on August 5, 1861, President Abraham Lincoln became the first head of state to levy a federal income tax. He did this to support the Civil War’s financial needs. Any yearly incomes exceeding $800 were subject to a 3% tax.
When Must Federal Income Tax Be Paid?
Federal income taxes are typically payable on April 15 of each year. If April 15 comes on a weekend or for other reasons, the day may change somewhat.
the conclusion
All sources of income that make up a taxpayer’s taxable income, including as wages, salaries, commissions, bonuses, gratuities, investment income, and some kinds of unearned income, are subject to federal income taxes, which are referred to as a marginal tax or progressive tax. The tax rates and brackets that apply to single filers, married people filing separate or joint returns, and heads of households are updated annually by the IRS.
