Understanding Business Tax Extensions
What is a Business Tax Extension?
A tax extension for business deadline gives you extra time to file your business tax return but not to pay any taxes owed. It’s a simple way to avoid late filing penalties if you’re not ready by the original due date.
Most businesses file an extension using Form 7004, which is quick, straightforward, and (thankfully) automatic upon submission.

Estimated Tax Payments for Businesses
What Are Estimated Tax Payments?
If your business doesn’t withhold taxes automatically, you’re expected to make quarterly estimated payments. These help you avoid penalties and a hefty tax bill in tax season.
Quarterly Payment Due Dates:
- April 15
- June 15
- September 15
- January 15 (of the following year)
Businesses use Form 1040-ES to make these payments and stay on the IRS’s good side. The third estimated tax payment is due September 15, so plan accordingly.

Tax Extension Process
How to File for a Business Tax Extension
Filing an extension is easy—just submit Form 7004 by your original tax deadline. Once filed, you’ll automatically get an extra six months to finalize your tax return.
You can file electronically through the IRS e-file system or send it by mail (but seriously, who wants to deal with snail mail?).
State Business Tax Extensions
Do You Need a State Tax Extension?
Not all states follow federal tax extension rules. Some states grant automatic extensions when you file a federal extension, while others require a separate request.
Pro Tip: Check with your state’s tax authority to avoid any last-minute surprises.
Cautions and Penalties
What Happens If You Miss a Payment?
IRS penalties aren’t fun, so it’s best to avoid them. Here’s what could happen if you’re late:
- Late payment penalty – 0.5% of unpaid taxes per month (up to 25%).
- Late filing penalty – 5% of unpaid taxes per month (up to 25%).
- Interest – Starts accruing from the original due date.
Moral of the story? File on time, even if you can’t pay everything immediately.

FAQs About Business Tax Extensions
1. Do business tax extensions apply to payroll taxes?
No, payroll taxes must still be paid on time. A tax extension only applies to filing your business tax return, not paying taxes owed.
2. Can I still get a tax refund if I file a tax extension?
Yes! If you’re due a tax refund, filing an extension won’t impact your ability to claim it. However, the sooner you file, the sooner you’ll receive your refund.
3. What are the key tax deadlines for C corporations?
C corporations must file their income tax returns (Form 1120) by April 15, 2025, or request an extension.
4. Do sole proprietors need to file Form 7004 for an extension?
No. Sole proprietors file their individual income tax return (Form 1040) and use Form 4868 to request an extension rather than Form 7004. Both freelancers and sole proprietors can benefit from our detailed guide on tax planning.
5. What happens if I miss the third estimated tax payment?
Missing an estimated tax payment can result in interest charges and penalties. If you’re unsure about estimated payments, consult a tax professional.
