Guide you through the most important tips, from gathering your records, to choosing the right IRS form, to knowing when to claim the standard or itemized deduction, to e-filing, and to avoiding common mistakes.

1. Documents Needed to File Taxes

The first step is to collect all the information you will require prior to commencing your return.

Having all of your paperwork prepared can cut down on errors and expedite the filing process. The IRS suggests gathering your tax forms, personal information, and any documentation for deductions and credits.

Personal Information

You may need:

• Social Security numbers or applicable taxpayer identification numbers
• Dates of birth for yourself and dependents
• Bank account and routing information
• A copy of your previous tax return
• Your previous year’s adjusted gross income (AGI), when required for verification
• Address and filing-status information

Income Documents

Your income documents depend on how you earned money during the year.

Common examples include:

• W-2 wage and salary form
• 1099-NEC form for specific independent-contractor earnings
• Form 1099-MISC for various miscellaneous income2
• Form 1099-INT is used for assessing taxable interest.
• Form 1099-DIV for dividends and distributions
• 1099-R of forms 1099-R for some retirement distributions
• Form SSA-1099 for Social Security bene
• Brokerage statements for investments
• Records of cryptocurrency or other digital-asset transactions
• Records of self-employment income
• Statements from payment platforms and online marketplaces

The IRS specifically advises taxpayers to gather records covering wages, interest, dividends, freelance work, retirement distributions, Social Security, digital assets, and other income sources.

Documents for Deductions and Credits

Depending on your circumstances, you may also need records for:

• Mortgage interest
• Property taxes
• Charitable contributions
• Childcare or dependent care
• Retirement contributions
• Health savings account contributions
• Eligible education expenses
• Medical and dental expenses
• Business expenses
• Tax installment payments.

Do not claim a deduction or credit merely because you have a receipt. First check that you qualify for the particular tax benefit.

2. Choosing the Right Tax Form

Almost every individual taxpayer will file, at a minimum, Forms 1040, U.S. Individual Income Tax Return.

There are also other schedules and forms for taxpayers in other situations offered by the IRS. In the 2026 filing season, 1040 form and schedules were available on the IRS filing systems.

For submitting your Form 1040

The U.S. 1040 is the primary federal individual income tax document.

It can be used by many taxpayers, including people earning income from:

• Employment
• Investments
• Retirement accounts
• Self-employment
• Other taxable sources

You will also need to complete other schedules if you have extra income, deductions, credits, or other situations.

The form 1040-SR

Additional Schedules

Your tax situation may require additional schedules.

Examples include schedules associated with:

• Additional income
• Additional deductions
• Additional taxes
• Tax credits
• Self-employment
• Itemized deductions
• Capital gains and losses

Don’t choose forms solely based on what you used last year. Your filing requirements can change when your financial or personal circumstances change.

3. Standard vs. Itemized Deductions

One of the most important decisions on a federal income tax return is whether to use the standard deduction or itemize eligible deductions.

A deduction reduces the amount of income subject to tax.

What Is the Standard Deduction?

The standard deduction is a fixed deduction amount determined primarily by filing status and other qualifying circumstances.

For tax year 2025, the standard deduction is:

Filing Status	Standard Deduction
Single	$15,750
Married Filing Jointly	$31,500
Head of Household	$23,625
Married Filing Separately	$15,750

These are the 2025 amounts used for returns filed during the 2026 filing season.

What Are Itemized Deductions?

Itemizing means separately listing eligible deductions rather than taking the standard deduction.

Potential itemized deductions can include qualifying amounts related to:

• Certain medical and dental expenses
• State and local taxes
• Mortgage interest
• Charitable contributions
• Certain casualty or theft losses
• Other eligible expenses

The IRS generally recommends taking the larger applicable deduction because it can reduce taxable income more.

Which Should You Choose?

A simple rule is:

Compare your eligible itemized deductions with your standard deduction.

If your itemized deductions are lower than the standard deduction, the standard deduction may generally provide the greater deduction.

However, don’t make the decision based only on one expense. Add all eligible itemized deductions together and compare the total with the applicable standard deduction.

Tax software can also help compare the available options.

4. E-Filing Your Tax Return

Electronic filing, commonly called e-filing, allows taxpayers to submit their federal tax returns electronically.

For many taxpayers, e-filing is convenient because tax software can guide you through questions, calculations, deductions, credits, and required forms.

Step 1: Choose an E-Filing Method

You can generally file using:

• IRS Free File, if eligible
• Commercial tax software
• A professional tax preparer
• Other IRS-authorized electronic filing options

For the 2026 filing season, the IRS states that Free File was available to taxpayers with adjusted gross income of $89,000 or less, while taxpayers above that threshold could use Free File Fillable Forms.

Step 2: Enter Your Information

You’ll typically provide information about:

• Filing status
• Dependents
• Income
• Tax withholding
• Deductions
• Credits
• Investments
• Self-employment
• Other applicable tax items

Tax software can automatically perform many calculations, but you are still responsible for reviewing the information before submitting your return.

Step 3: Review Your Return

Before submitting, carefully check:

• Name spelling
• Social Security numbers
• Bank account information
• Filing status
• Dependent information
• Income figures
• Federal withholding
• Deductions
• Credits
• Investment information

Step 4: Sign Electronically

Electronically sign and submit your return as instructed by the software.

Hold confirmation that your return has been received and accepted.

Step 5: Track Your Refund or Payment

If you‘re getting a refund, Direct Deposit is almost always more rapid than Receiving a Check in the Mail.

Ensure you have the details of how to make any tax payment, and the due date.

5. Common Tax Filing Mistakes

Even small mistakes will delay or require you to rectify a return.

The following are a few of the most common mistakes that taxpayers need to be aware of.

1. Forgetting Income

One of the most common errors is not including a source of income when it should be included.

Do not make the mistake of thinking because you did not receive a regular W-2 that your source of income can be disregarded.

Take a close look at your bank, brokerage, payment-platform, freelance, and other records.

2. Entering the Wrong Social Security Number

Any incorrect digit can cause issues with return handling or dependent claim processing.

Make sure the taxpayer and each dependent identification number have been triple-checked prior to filing.

3. Choosing the Wrong Filing Status

Your filing status has an impact on the way your taxes are calculated and how much you are entitled to be deducted. Your filing status may also determine whether you are able to claim a tax credit.

Common statuses include:

• Single
• Married Filing Jointly
• Married Filing Separately
• Head of Household
• Qualifying Surviving Spouse

Choose the status that accurately reflects your circumstances.

4. Missing Tax Credits

Some taxpayers focus on deductions and overlook potentially available tax credits.

Depending on your circumstances, credits may relate to:

• Children and dependents
• Education
• Retirement savings
• Energy improvements
• Other qualifying expenses

Review the IRS requirements for each credit rather than assuming you qualify.

5. Incorrect Bank Information

If you request direct deposit, carefully verify your bank account and routing numbers.

Incorrect information can cause problems with receiving your refund.

6. Forgetting to Report Investment or Digital-Asset Activity

Investment sales, dividends, interest, and digital-asset transactions can create tax reporting obligations.

Keep complete records rather than relying solely on memory.

7. Claiming Unsupported Deductions

A deduction should be supported by appropriate records and meet the applicable tax rules.

Don’t inflate expenses or claim personal costs as business deductions simply to reduce taxable income.

8. Failing to Review the Final Return

Don’t submit your return immediately after completing the last question.

Take time to review the entire return for errors and missing information.
