Your Guide to Filing a Business Tax Extension in 2025

Filing taxes is a critical part of running a business in the United States. But sometimes, despite our best efforts, the paperwork piles up, deadlines sneak up, or important documents go missing. When that happens, filing a business tax extension can give you the time you need to get things in order. This guide will walk you through everything you need to know about filing a business tax extension in 2025, from important deadlines to step-by-step instructions.

What is a Business Tax Extension?

A business tax extension is extra time the IRS gives you to file your business tax return. It is important to remember that this extension does not give you more time to pay your taxes. You must still pay the taxes you owe by your regular tax deadline. The extension only gives you more time to complete and submit your tax return forms accurately.
Filing an extension is often the best option if you’re waiting on documents, working with a busy tax advisor, or dealing with a complicated financial situation. It helps you avoid penalties for filing late, and it gives you more breathing room to make sure everything is correct.

Key Tax Deadlines for Businesses in 2025

Understanding the due dates is essential if you plan to file a tax extension. These are the main deadlines for 2025 for businesses that follow the calendar year:

• S Corporations and Partnerships: The Original deadline is March 15, 2025. The extended deadline is September 15, 2025.
• C Corporations: The Original deadline is April 15, 2025. The extended deadline is October 15, 2025.
• Sole Proprietors and Single-Member LLCs: These are filed with your personal tax return, so the original deadline is April 15, 2025, and the extended deadline is October 15, 2025.

If your business follows a fiscal year that is not the calendar year, your deadlines may be different. Check with your accountant or the IRS for those specific dates.

Why File a Business Tax Extension?

There are many good reasons to file for a business tax extension:

• Missing Documents: Sometimes, banks, vendors, or clients are late sending needed documents.
• Busy Season: Tax professionals are extremely busy during tax season. An extension allows for more personalized and careful service.
• Complex Finances: If your business had unusual or complicated activity during the year, you might need more time to make sure everything is reported correctly.
• Avoiding Mistakes: Rushing leads to errors. Extensions give you time to double-check your information.

Filing an extension is much better than submitting a rushed or incorrect return. It shows the IRS that you’re taking steps to comply responsibly.
In some cases, you might be waiting on final numbers from a third-party accountant or bookkeeping team. Other times, there might be changes in your business structure, such as switching from a sole proprietorship to a corporation, that require extra time to process the correct forms and understand the tax impacts. Filing an extension gives you the breathing space you need to handle these changes thoroughly.

How to File a Business Tax Extension

Filing a business tax extension is a straightforward process. Here are the steps:

Step 1: Choose the Correct Form

• Form 7004: This is the form used by C corporations, S corporations, partnerships, and multi-member LLCs.
• Form 4868: This is for sole proprietors and single-member LLCs, and it's filed with your personal tax return.

Step 2: Submit the Form

You can submit your form in one of the following ways:

• Electronically through IRS Free File: This is the easiest and fastest option.
• Using Tax Software: Most tax software programs support extension filing and will guide you through the steps.
• By Mail: You can also print the form and mail it to the IRS. Make sure it’s postmarked by the original deadline.

Step 3: Estimate and Pay Your Taxes

You must estimate your tax liability and pay any taxes due by your original deadline. Even if your extension is approved, the IRS expects full payment by the original due date. If you don’t pay on time, you could face interest and penalties.

What Happens After You File?

Once your extension is submitted and accepted, you’ll have up to six more months to file your full return. Here’s what you should do during this time:

• Gather All Documents: Collect everything you need—income reports, receipts, expense records, bank statements, payroll reports, and more.
• Check Your Deductions: Review what business expenses are deductible, like office supplies, rent, equipment, and travel.
• Organize Your Books: Finalize your accounting records and make sure everything matches up.
• Consult Your CPA: Go over everything with a tax professional before submitting your final return.

This extra time can help you file a more accurate return and reduce your chances of being audited.

Use the extension period wisely. It’s a great opportunity to review your financial practices, update your accounting systems, and plan ahead for the next tax year. You can also take time to learn about tax-saving strategies that could benefit your business in the future. Being proactive now could help you save money and time down the line.

Penalties to Avoid

It’s important to remember that while filing an extension gives you more time to file, it doesn’t give you more time to pay. If you miss the payment deadline, the IRS may charge:

• Late Filing Penalty: 5% of unpaid taxes per month (up to 25%).
• Late Payment Penalty: 0.5% of unpaid taxes per month (up to 25%).

Paying as much as you can by the original deadline can help reduce these charges. If you’re not sure how much you owe, make your best estimate.
The IRS may also charge interest on any unpaid tax amount, so even small delays can result in extra costs. The best approach is to pay what you can and work with a tax advisor if you need help calculating your estimated payment.

State Tax Extensions

Many states follow federal extension rules, but some do not. Check your state’s tax website or talk to your CPA to find out if you also need to file a state extension form or pay state taxes by a different deadline.
State penalties can be different from federal penalties, and state tax laws vary widely. If your business operates in multiple states, you may have additional filing responsibilities. It’s always best to double-check the rules for each state where you do business.

Special Situations: Natural Disaster Relief

If your business is located in an area affected by a federally declared disaster, you may automatically receive extra time to file and pay taxes. The IRS often provides this relief without requiring you to file a form. Keep an eye on the IRS Disaster Relief webpage or contact your tax advisor for updates.
In 2025, businesses affected by events like hurricanes, wildfires, or floods may receive special filing extensions. If you're in one of these areas, confirm your eligibility by visiting the IRS website or checking news releases related to disaster declarations.

Tips for Next Year

To avoid needing an extension in the future, try these best practices:

Keep Good Records Year-Round: Organize receipts and track expenses regularly.
Use Accounting Software: Programs like QuickBooks or Xero make it easier to stay on top of finances.
Work With a CPA Year-Round: Check in with your accountant regularly, not just at tax time.
Set Monthly Reminders: Review your income and expenses at the end of each month.
Start Early: Don’t wait until March or April to begin preparing your tax documents.

Consider setting quarterly goals for your financial tasks. For example, each quarter, review your income statement, balance sheet, and cash flow statement. This regular review can help catch mistakes early and reduce last-minute surprises. Also, stay updated on tax law changes that could impact your business.
