The 10 Integral Tax Forms You Should Be Aware Of
Tax season can feel overwhelming, but understanding the right forms can make all the difference. These 10 essential tax forms cover everything from reporting income to claiming deductions and requesting extensions. They are the backbone of an accurate and efficient filing process. Whether you’re an individual taxpayer, small business owner, or freelancer, knowing these forms will help you stay compliant and maximize your tax benefits.
1) Form 1040: U.S. Individual Income Tax Return
Purpose: Form 1040 is the central tax return document for individual taxpayers in the U.S. Taxpayers use it to report annual income, calculate tax liabilities, claim deductions and credits, and determine their refund or amount owed. It’s the foundation of the tax filing process and provides an overview of a taxpayer’s financial year.
Who Needs It: Nearly all U.S. taxpayers must file a Form 1040 if they meet minimum income thresholds, which vary by age, filing status, and other factors. Whether you’re employed, self-employed, or earning income from investments, you’ll use Form 1040 to report your earnings to the IRS.
Highlights for 2025: This year, taxpayers should note several updates:
- Tax Bracket Adjustments: Due to inflation adjustments, the income ranges for each tax bracket have shifted. This change could impact tax rates for many filers.
- Standard Deduction Increase: The IRS has raised the standard deduction amounts. This provides a potentially larger tax deduction for those who do not itemize.
- Updated Credits and Deductions: Changes to credits like the Earned Income Tax Credit (EITC) and Child Tax Credit may affect eligibility. Benefit amounts could also change depending on income and family size.
2) Form 1040 (Schedule A): Itemized Deductions
Purpose: Schedule A is an attachment to Form 1040 that allows taxpayers to itemize specific deductions, rather than taking the standard deduction. By itemizing, taxpayers can deduct certain expenses like mortgage interest, charitable contributions, state and local taxes, and medical expenses that exceed a percentage of income. This option can be advantageous for those with deductible expenses that total more than the standard deduction amount.
Who Needs It: Schedule A is ideal for taxpayers whose qualifying deductible expenses are higher than the standard deduction. Commonly, this includes homeowners with significant mortgage interest. It also applies to individuals with large medical expenses, charitable donations, or high state and local taxes.
2025 Tax Strategies:
- Track Charitable Donations: Keep detailed records of both cash and non-cash charitable donations. These can significantly reduce taxable income when itemized.
- Maximize Mortgage Interest: Homeowners should include mortgage interest from qualified loans, since it often counts as a major itemized deduction.
- Bundle Medical Expenses: If possible, schedule large, elective medical expenses within the same tax year. This can help exceed the 7.5% income threshold for medical deductions.
- Consider SALT Limits: Be mindful of the state and local tax (SALT) deduction cap, which remains at $10,000. For those in high-tax states, other itemized deductions might provide additional benefits.

3) Form 1040 (Schedule C): Profit or Loss from Business
Purpose: Sole proprietors, freelancers, and independent contractors use Schedule C to report income and expenses. It lets business owners calculate their net profit or loss and transfer that amount to Form 1040 as part of their total taxable income. This form is essential for accurately reporting business income and claiming deductions for expenses like office supplies, travel, and equipment.
Who Needs It: Any self-employed individual, independent contractor, or small business owner operating as a sole proprietor needs to complete Schedule C. Those who earn income from side gigs or freelance work also need to file it.
2025 Updates:
- Qualified Business Income (QBI) Deduction: Many small business owners can claim the QBI deduction. It offers up to a 20% deduction on qualified business income. Understanding if and how this applies can significantly reduce taxable income.
- Home Office Deduction: For those who work from home, expenses related to a dedicated workspace can be deductible. This includes a portion of utilities, rent, and home maintenance. The deduction is based on the percentage of your home used exclusively for business.
- Health Insurance Deduction: Self-employed individuals may be eligible to deduct health insurance premiums for themselves and their families.
- Mileage Deduction Update: For 2025, the IRS may have adjusted the standard mileage rates for business travel. Be sure to use the current rate when calculating travel expenses.

4) Form W-4: Employee’s Withholding Certificate
Purpose: Form W-4 allows employees to control the amount of federal income tax withheld from their paychecks. By providing information about filing status, dependents, and other adjustments, employees can better align their withholdings with their tax obligations to avoid owing taxes or receiving a large refund at the end of the year.
Who Needs It: Employees starting a new job or going through life changes—such as marriage, divorce, or having a child—should complete a new W-4. It’s also helpful for anyone with a major change in income. This includes taking on a second job or a freelance side gig. It is important to understand the difference between a W-2 and a W-4. Simply put, the W-2 reports what has already happened (earnings and taxes withheld over the year). The W-4 determines what will happen (how much tax to withhold from future paychecks).
Importance in 2025:
- Updated IRS Withholding Calculator: For 2025, the IRS’s updated online calculator can help employees estimate the right withholding amount. It’s based on their personal and financial situations.
- Tips for Optimal Withholding: If you received a large tax refund or owed taxes last year, your W-4 may need adjusting. Review your withholding allowances and account for additional income or deductions. This helps align your tax payments with your expected liability.
- Additional Withholding Adjustments: Have side income or want to withhold more for tax purposes? Adding extra withholding on your W-4 can help cover the additional tax due.
5) Form W-9: Request for Taxpayer Identification Number (TIN) and Certification
Purpose: Businesses use Form W-9 to request and record the Taxpayer Identification Number (TIN) of contractors, freelancers, and other non-employee service providers. The form ensures that businesses have the necessary information to report payments made to these individuals accurately.
Who Needs It: Independent contractors, freelancers, and anyone providing services to a business typically need to complete a W-9. Individuals and businesses also use it to report income from rents, royalties, and other miscellaneous sources on a 1099 form.
Key 2025 Considerations:
- Common Uses: Form W-9 is essential for businesses issuing 1099 forms, like the 1099-NEC (Nonemployee Compensation) and 1099-MISC. By collecting TINs, businesses can accurately report contractor payments and send that information to the IRS.
- Importance of ITINs: Individuals who aren’t eligible for a Social Security Number (SSN), such as certain non-U.S. residents, can use an Individual Taxpayer Identification Number (ITIN) on Form W-9. This allows them to comply with reporting requirements, ensuring accurate tax records. Click here to learn how to apply for an ITIN.
- Ensuring Accurate Income Reporting: Completing a W-9 accurately helps avoid IRS mismatches in records, which can lead to unnecessary tax notices or withholding penalties.
- Electronic Submissions: Many businesses now allow W-9 submissions electronically, simplifying the process and ensuring timely filing for contractors and freelancers.
6) Form 1099-MISC: Miscellaneous Income
Purpose: Form 1099-MISC is used to report a variety of income types that don’t fit under wages or salary, such as rent payments, royalties, prizes, awards, and other miscellaneous payments. This form ensures the IRS is aware of income earned outside of traditional employment, which is not subject to regular payroll tax withholding.
Who Needs It: Freelancers, independent contractors, landlords, and others who receive non-employee income typically need to report earnings using Form 1099-MISC. Payers are responsible for issuing this form to recipients if the amount paid meets reporting thresholds.
New for 2025:
- Updated Reporting Thresholds: Certain income types may have adjusted reporting thresholds, so payers should verify the minimum amounts that require a 1099-MISC to be issued.
- Clarified Guidelines for Specific Income Types: The IRS has provided updated guidance on categorizing and reporting various income types to ensure accuracy and reduce errors in filing.
- Electronic Filing Encouragement: As part of ongoing efforts to streamline tax reporting, the IRS is encouraging more businesses to use electronic filing options for 1099 forms, including the 1099-MISC, which simplifies record-keeping and reduces errors.
7) Form 1099-INT: Interest Income
Purpose: Form 1099-INT is used to report interest income earned from sources like bank accounts, certificates of deposit, and other interest-bearing financial accounts. The form provides information on the total interest paid to an individual over the year, which is generally taxable and must be reported on the individual’s tax return.
Who Needs It: Individuals with accounts that generate interest—such as savings accounts, money market accounts, and certain investment accounts—will receive a 1099-INT from their financial institutions if their earned interest meets the IRS reporting threshold.
2025 Filing Tips:
- Verify Your Interest Amounts: Make sure the amount reported on Form 1099-INT matches your bank records. Errors in reporting can lead to discrepancies and potential IRS inquiries.
- Include All Interest: Even if you don’t receive a 1099-INT for small amounts (under $10, for example), you still need to report all interest income on your tax return.
- Account for Tax-Exempt Interest: Some interest, like that from municipal bonds, may be tax-exempt, but you still need to report it. Review your 1099-INT, which lists tax-exempt interest separately, to ensure accurate reporting.
- Foreign Interest Income: If you have accounts in foreign banks, report that interest income—even if you don’t receive a 1099-INT. The IRS requires you to report global income, including interest from foreign accounts.
8) Form 1099-DIV: Dividends and Distributions
Purpose: Form 1099-DIV is issued to report dividend income earned from investments in stocks, mutual funds, and other equity securities. It also includes information on capital gains distributions and other relevant payouts to shareholders. This form ensures that dividend income and distributions are properly reported on the taxpayer’s return.
Who Needs It: Investors and shareholders who receive dividends or distributions from their investments. Financial institutions and brokerage firms are required to issue a 1099-DIV if the amount of dividends paid meets the IRS reporting threshold.
Focus for 2025:
- Updated Reporting Thresholds: As of 2025, the IRS has maintained the reporting threshold for dividends at $10, meaning financial institutions must issue a 1099-DIV for any dividends paid above this amount.
- Qualified vs. Ordinary Dividends: Form 1099-DIV separates qualified dividends, which are taxed at a lower capital gains rate, from ordinary dividends, which are taxed as regular income. This distinction remains crucial for tax planning and reporting.
- Capital Gains Distributions: Investors should also note capital gains distributions listed on the form, as they need to be reported separately for accurate tax calculations.
- Foreign Dividends: Investors with international holdings may receive foreign dividends that could require special reporting or be subject to foreign tax credits.
9) Form 4868: Application for Automatic Extension of Time To File U.S. Individual Tax Return
Purpose: Form 4868 allows taxpayers to request an automatic six-month extension to file their federal income tax return. This form is particularly useful for those who need additional time to gather financial records or handle complex tax situations. Filing Form 4868 extends the return filing deadline but does not extend the deadline to pay any taxes owed.
Who Needs It:
- Taxpayers who are unable to complete their tax return by the original due date, typically April 15th (or the next business day if it falls on a weekend or holiday).
- Individuals waiting for critical tax documents, such as K-1s from partnerships or late-issued 1099 forms.
- Taxpayers dealing with unexpected personal or financial challenges that delay filing.
Important for 2025:
- Deadlines: Form 4868 must be filed by April 15th, 2025, to avoid late-filing penalties. If approved, the extension provides a new filing deadline of October 15th, 2025.
- Penalties: While Form 4868 prevents late-filing penalties, it does not waive penalties or interest for unpaid taxes. Taxpayers should estimate and pay any taxes owed by the original deadline to avoid accruing additional charges.
- Electronic Filing: Taxpayers can file Form 4868 electronically, which ensures faster processing and confirmation of the extension request.
10) Form 4506-T: Request for Transcript of Tax Return
Purpose: Form 4506-T is used by taxpayers to request a transcript of a previously filed tax return. Unlike a full copy of the return, a transcript provides a summary of key information, such as income, filing status, and tax payments, which is often sufficient for financial or verification purposes.
Who Needs It:
- Individuals applying for loans, mortgages, or financial aid, where proof of income or tax history is required.
- Taxpayers needing to verify information for correcting errors on their tax return.
- Businesses or individuals responding to IRS inquiries or audits that require supporting documentation from prior tax years.
Key Considerations in 2025:
- Accessing Transcripts Efficiently: Taxpayers can now use the IRS’s online tool, “Get Transcript Online,” for immediate access to digital transcripts. Alternatively, Form 4506-T can be mailed or faxed to request a transcript, though processing times may vary.
- Types of Transcripts Available: Depending on the need, taxpayers can request various types of transcripts, including the Tax Return Transcript, Tax Account Transcript, or Record of Account, each providing different levels of detail.
- Usage in Financial Transactions: Many lenders and financial institutions rely on Form 4506-T to confirm income and tax history, making it a critical form for those involved in loans or refinancing processes.
