2. What Is Form 1040?

Form 1040, officially called “U.S. Individual Income Tax Return,” is the standard form used by individual taxpayers to report their income to the IRS 

Who Needs to File?

• U.S. citizens or residents with income above a certain threshold (e.g., $14,600 for single in 2024) 

• Anyone with special tax situations—like self-employment income over $400, alternative minimum tax, or HSA distributions—must file, regardless of income 

3. Core Sections of Form 1040

Form 1040 is organized like a “building block” – you complete the main form and attach only the schedules relevant to your situation 

A. Personal Information

• Basic details: name, address, filing status, SSN, dependents

• Ensure accuracy – errors here can delay your return or refund

B. Income Reporting

Report all income types: wages, interest, dividends, capital gains, retirement distributions, unemployment, etc. 

C. Adjustments & Deductions

• Standard Deduction – A fixed deduction based on filing status; e.g., $14,600 for single filers in 2024

• Above-the-line adjustments – Subtractible before deductions (e.g., student loan interest, retirement contributions)

D. Tax Calculation

• Use tax tables (based on taxable income) to find your tax 

• Add additional taxes like self-employment or AMT if applicable

E. Credits & Payments

• Tax credits reduce what you owe dollar-for-dollar (e.g., child tax credit, education credit)

• Payments already made via withholding or estimated taxes are entered here

F. Refund or Amount Owed

• If your total payments exceed your tax, you get a refund

• Otherwise, you owe the difference—remember, paying late can trigger penalties irs.gov

4. Supporting Schedules: When Do You Need Them?

Schedule	Purpose
Schedule 1	Income not covered on main form (e.g., business, rental, unemployment)
Schedule 2	Additional taxes (e.g., self-employment tax, AMT)
Schedule 3	Non-refundable credits & other payments
Schedule A	Itemized deductions (e.g., mortgage interest, medical expenses)
Schedule B/C/D/E/F/SE	Specific income sources like interest/dividends, business, capital, supplemental, farm, self-employed

5. Key Stats & Trends

• The IRS processes around 140 million individual returns, with a 1.5% increase in processed returns and refunds averaging $2,945 in 2025

• Over 73 million e-filed returns were filed through professionals; roughly 64 million were self-prepared

• Filing season stats show around 95% of returns filed by mid-season, representing 87% of Adjusted Gross Income and 82% of tax liability
