What Is File a Tax Extension Form 4868?
The official title of Form 4868 is “Application for Automatic Extension of Time to File U.”. S. . The paperwork taxpayers use to ask for more time to finish their federal tax returns is called an “individual income tax return.” When properly filed by April 15, 2025, this form grants an automatic six-month extension, moving your filing deadline to October 15, 2025.
The form itself is relatively straightforward, requiring basic identification information and an estimate of your tax liability. The IRS does not require you to provide a reason for requesting the extension, making this a penalty-free option for anyone who needs additional time. You have more time to file your federal tax return with a tax extension, but you won’t have to pay any taxes that are due.
- New filing deadline: October 15, 2025
- Payment deadline: April 15, 2025
If you owe taxes, you must estimate and pay the amount due by April 15 to avoid interest and penalties. Filing later without paying on time can result in costly charges.
Benefits of Filing a Tax Extension
Filing an extension through Form 4868 offers several advantages:
- Avoids late filing penalties, which can be substantial at 5% of unpaid taxes per month, up to 25%
- Provides additional time to gather documentation and ensure accuracy
- Gives taxpayers experiencing personal emergencies breathing room to focus on pressing matters
- Allows self-employed individuals and business owners more time to compile complex financial records
- Provides extra time for tax planning strategies that might reduce your overall tax liability
- Reduces the likelihood of errors that could trigger an IRS audit
Tax professionals often recommend extensions for clients with complicated tax situations as a strategic tax planning tool rather than a last resort.

How To File a Tax Extension (Form 4868)
Step 1: Gather Your Tax Information
Before completing Form 4868, collect your available tax documents to make the most accurate estimate possible of your tax liability. This includes:
- W-2 forms from employers
- 1099 forms for independent contractors and other income
- Records of estimated tax payments already made
- Previous year’s tax return for reference
- Documentation of deductible expenses
Making a sincere attempt to accurately estimate your liability helps you avoid penalties, even if your estimate isn’t perfect.
Step 2: Complete Form 4868
The form requires the following information:
- Your name, address, and Social Security number (and spouse’s, if filing jointly)
- Estimate of total tax liability for 2024
- Total of payments already made for 2024
- Balance due (if any)
- Amount you’re paying with the extension request
When calculating your estimated tax liability, consider all income sources and potential deductions. If uncertain, it’s generally better to overestimate rather than underestimate your tax obligation.
Step 3: Choose Your Filing Method
Several options exist for submitting Form 4868:
- Commercial tax software or electronic filing via the IRS Free File program.
- Direct submission through your tax professional
- Paper filing by mail to the appropriate IRS service center
- Payment made electronically with a clear indication that it is for an extension.

- Electronic funds withdrawal if e-filing
- Direct Pay from your bank account via the IRS website
- Credit or debit card payments (processing fees apply)
- Electronic Federal Tax Payment System (EFTPS)
- Check or money order if filing by mail

Once submitted, store confirmation of your extension filing in a safe place. This documentation proves you requested the extension in case questions arise later.
For electronic filings, save the confirmation number or acknowledgment. To ensure that the forms are filed on time, use certified mail and include a return receipt.

Special Situations and Considerations

U.S. citizens and resident aliens living abroad automatically receive an extension until June 15, with the option to request an additional extension to October 15 using Form 4868.
Disaster Victims
The IRS often provides automatic tax relief for victims of federally declared disasters, including extended filing and payment deadlines. These extensions typically don’t require Form 4868. Check the IRS website for current disaster relief provisions if you’ve been affected by a recent natural disaster.
State Tax Extensions
Most states recognize the federal extension automatically, but some require a separate state extension request. Each state has its own rules regarding:
- Whether a separate state form is required
- Payment requirements for estimated state taxes due
- Deadline alignment with federal extensions
Research your specific state’s requirements or consult with a tax professional to ensure compliance with both federal and state regulations.

- Attaching a copy of Form 4868 is not necessary.
