The Internal Revenue Service (IRS) requires most U.S. citizens and resident aliens to report their income and file tax returns each year. The IRS uses these reports to verify that you have paid the correct amount of federal income tax. Understanding who must file and when can help you stay in compliance with federal tax laws.

For the 2024 tax year, you generally must file a federal income tax return if your gross income exceeds certain thresholds. These thresholds depend on your age, filing status, and type of income. For example, in 2024, a single person under 65 must file if their gross income was $14,600 or more. A married couple filing jointly, both under 65, must file if their combined gross income was $29,200 or more. These numbers increase slightly each year to account for inflation.
Gross income includes wages, salaries, tips, self-employment income, interest, dividends, capital gains, and other forms of compensation. Even if your income falls below the filing threshold, you may still benefit from filing a return. Many people file returns to claim refundable tax credits, such as the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit, which can result in payments from the government even if no tax was owed.
The filing deadline for most people is April 15 each year. However, this date can shift if April 15 falls on a weekend or holiday. The IRS website publishes the exact deadline each year. If you cannot file by the deadline, you can request an extension, which typically gives you six additional months to submit your return.
Practical Takeaway: Calculate your gross income from all sources to determine whether you must file. If your income exceeds the threshold for your filing status, you are required to file a federal return, even if you believe no tax is owed. Visit IRS.gov to find the current year's income thresholds for your situation.
The IRS requires you to report all income you receive during the tax year, regardless of whether you received a formal document reporting it. Income is broadly defined and includes not only wages and salaries but also many other forms of compensation and economic benefit.

Wages and salaries from employment must be reported. Your employer should provide you with a Form W-2 by January 31 each year, which shows your wages and taxes withheld. You will receive one W-2 for each employer you worked for during the year. Self-employed individuals and those with business income must report this income on Schedule C. If you earned $400 or more from self-employment in a year, you generally must file a return and report this income.
Investment income must also be reported. This includes interest earned from savings accounts and certificates of deposit, which your bank reports on Form 1099-INT; dividend income from stocks and mutual funds, reported on Form 1099-DIV; and capital gains from the sale of stocks, real estate, or other assets. If you sold investments at a profit, you must report the gain. Conversely, investment losses can sometimes be deducted to offset gains.
Other types of reportable income include rental income from property you own, retirement distributions from IRAs and 401(k) plans, Social Security benefits (in some cases), unemployment compensation, alimony received, and income from hobbies or side activities. The IRS considers most forms of economic benefit as income, even if received informally or in non-monetary form.
Many types of income are reported to both you and the IRS on information return forms (Forms 1099). When you receive a 1099 form, the IRS receives a copy as well. Mismatches between what you report and what the IRS has on file can trigger audits or correspondence. Employers and financial institutions are required by law to issue these forms and report income to the IRS.
Practical Takeaway: Gather all Forms W-2 and 1099 before preparing your return. These forms show the income the IRS already knows about. Report all income from all sources on your return, even income not shown on a 1099 form, to ensure accuracy and avoid discrepancies with IRS records.
After reporting your income, you can reduce your taxable income through deductions and increase your refund through credits. Understanding the difference between these two types of tax benefits is essential for accurate reporting.

Deductions reduce the amount of income subject to federal tax. There are two ways to deduct: you can take the standard deduction, or you can itemize deductions. The standard deduction is a fixed dollar amount that depends on your age and filing status. For the 2024 tax year, the standard deduction is $14,600 for single filers under 65 and $29,200 for married couples filing jointly, both under 65. These amounts increase for people 65 and older. Most people use the standard deduction because it is simpler than itemizing.
If you choose to itemize, you list individual deductions such as mortgage interest, state and local taxes (limited to $10,000 annually), charitable contributions, and medical expenses exceeding 7.5% of your adjusted gross income. You should itemize only if your total itemized deductions exceed your standard deduction, which is true for a minority of filers.
Tax credits are different from deductions. A credit reduces your tax bill dollar-for-dollar. For example, if you owe $2,000 in tax and have a $500 credit, your tax bill becomes $1,500. Some credits are refundable, meaning that if the credit exceeds your tax liability, the IRS sends you the difference. The Child Tax Credit of up to $2,000 per qualifying child is one of the most common credits. The Earned Income Tax Credit can provide credits of $600 to $3,600 depending on income and family size.
Other common deductions include contributions to traditional IRA accounts, student loan interest (up to $2,500), and business expenses for self-employed individuals. Keeping records of deductible expenses throughout the year makes tax preparation easier and more accurate.
Practical Takeaway: Decide whether to take the standard deduction or itemize by calculating your total itemized deductions and comparing it to the standard deduction for your filing status. Keep receipts and documentation for all potential deductions throughout the year. Research tax credits for which you may be eligible, such as those for dependents, education, or earned income.
Self-employed individuals and business owners have specific IRS reporting requirements beyond those that apply to wage earners. Understanding these requirements is essential for compliance and for ensuring that you pay the correct amount of tax.

If you operate a business or are self-employed, you must report all business income on Schedule C of Form 1040. Business income includes revenue from services you provide, products you sell, or any other business activity. You do not net out expenses to determine whether you "really" owe taxes; you must report gross receipts and then deduct business expenses. Business expenses include cost of goods sold, rent for office space, equipment and supplies, advertising, professional fees, vehicle expenses, and other ordinary and necessary business costs.
Self-employed individuals must also pay self-employment tax on top of regular income tax. Self-employment tax covers Social Security and Medicare taxes and is calculated on Schedule SE. If your net self-employment income is $400 or more, you must file Schedule SE and pay self-employment tax. For 2024, the self-employment tax rate is 15.3% (12.4% for Social Security and 2.9% for Medicare) on net earnings. This is in addition to regular income tax owed.
The IRS allows you to deduct half of your self-employment tax as an adjustment to income, which reduces your taxable income. This partially offsets the burden of self-employment tax. Additionally, self-employed individuals can establish SEP-IRA or Solo 401(k) plans to save for retirement while reducing current taxable income.
If you hire employees for your business, you must withhold and remit payroll taxes. You must file Form 941 each quarter to report wages paid and taxes withheld. You must also issue Forms W-2 to employees by January 31 of the following year.
