The filing deadline for your federal income tax return is almost here. Have you filed your return yet?
As a small business owner, you are probably pulled in a million different directions. And while you have the best of intentions to get your taxes done and dusted by the filing deadline, sometimes you just can’t get it together in time. Maybe you’re still waiting on documents such as a K-1 from an investment, or maybe you’ve just been too preoccupied with keeping your business on track to prepare your return.
Whatever the reason may be, the IRS understands the reality of running out of time and makes it easy to file a business tax extension. If you’re not sure when business tax returns are due for your business structure, check out the table below. And the deadline to file a business tax extension is the same as the business tax filing due date, so take note!
|Business structure||Return due dates|
|Sole proprietorship||April 15|
|Single-member LLC||April 15|
|Multi-member LLC||March 15|
|S corporation||March 15*|
|C corporation||April 15*|
*These are the due dates for the calendar year entity (when the last day in your business year is December 31, 2020).
If you’re not sure how to file a tax extension, here’s everything you need to know to do it with confidence.
Why File a Business Tax Extension?
There are a lot of reasons why your business may need to file for a tax extension. The IRS understands that not everything always goes as planned, and sometimes you just need a little extra time to get it right. Some reasons you might need an extension include:
- You need more time to accurately file your business return
- You’re making retirement plan contributions and won’t have them completed by the initial tax deadline
- Some of the tax filing documents you need are missing or incorrect, and you’re waiting to receive the correct documents
But filing for an extension won’t help you out if you can’t make your business tax payment by the deadline. The extension is only a deadline for filing your taxes, not for paying them. You’ll need to pay any taxes due by the original deadline, or you will be charged interest and fees.
How to File for a Business Tax Extension
If that tax deadline is sneaking up on you and you think there’s a chance that you won’t be able to file your taxes by the due date, it’s time to file an extension. Here’s how to do that for each business entity type.
How to File a Tax Extension As a Sole Proprietor
Tax return: IRS Form 1040 with business Form Schedule C
Due date: April 15
The IRS makes filing for an automatic six month extension pretty painless with Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return.
If you expect to owe money, you’ll need to estimate the amount you owe and send a check along with the form for a tax extension.
When mailing your extension and payment, make sure to send them via certified mail, so you’ll have proof that your tax extension was filed on time. The IRS processes an enormous amount of mail every day, and things do get lost. If the IRS claims it did not receive your payment or extension by the due date, you could get hit with penalties. If you can provide proof that the check or extension was mailed by the due date, it will be deemed received on the day you mailed it, even if it is actually received days later.
If snail mail isn’t your thing, you may be able to e-file your extension using your tax preparation software of choice and make an estimated payment online using IRS Direct Pay. This secure service lets you pay directly from a checking or savings account for no additional fee, and you’ll get instant confirmation that your payment was submitted. Just select “Extension” under reason for payment, and make sure you choose the correct form and tax period to let the IRS know where to apply your payment. Keep in mind that making an extension payment through IRS Direct Pay alone does not extend your return. You’ll still need to mail Form 4868 or e-file the extension.
Calculating the estimated amount due can be a challenge if you’re not prepared to file your tax return, but your tax preparer or software may be able to help. Just provide as much information as you have, then use estimated amounts for the rest. If your tax situation has not changed much since you filed last year, that’s a good place to start.
And while you’re filing your federal return, don’t forget your state return. Some states will automatically extend your state return when you file a federal extension, but some require their own form. Ask your tax preparer, or check with your state’s Department of Revenue to see which form your state uses.
How to File a Tax Extension As a Partnership, Multi-member LLC, or S corporation
Tax return: IRS Form 1065 (partnership and multi-member LLC) and 1120 S (S corporation)
Due date: March 15
Partnerships, limited liability companies (LLCs), and S corporations use Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns to request an extension.
Because these entities are not taxed at the entity level on their income, you don’t need to send in an estimated tax payment with your extension Form 7004. Instead, you’ll need to also file an extension for your Form 1040, personal tax return. With that extension, you should determine the income that will flow through to your individual tax return, and pay estimated tax with your individual extension.
To file an individual extension and pay your estimated tax, you will use Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return.
How to File a Tax Extension As a C Corporation
As with partnership, LLC, and S corporation returns, C corporations use Form 7004 to file for an extension. The extension Form 7004 can be e-filed or mailed, but you should send it via certified or registered mail for proof of mailing if you choose not to e-file.
Like individuals, C corporations must pay any business tax due by the April 15 deadline, regardless of whether or not they file for an extension. Some corporations may mail a check for their estimated tax payment, but others are required to make payments using the Electronic Federal Tax Payment System (EFTPS).
Any business can voluntarily use the EFTPS system to make federal tax deposits, but businesses with a federal tax liability (including income, payroll, and excise taxes) exceeding $200,000 in any calendar year are required to use EFTPS starting with the second succeeding calendar year. You can enroll online, then make payments online or by phone. For more information on the EFTPS system, check out IRS Publication 4990, EFTPS Payment Instruction Booklet for Business and Individual Taxpayers.
Can You File Your Own Business Tax Extension?
If you haven’t found a tax preparer you like working with, or you just enjoy the DIY route, filing for a business tax extension is absolutely fine to do on your own. The IRS makes it easy to do so, giving you all of the forms you need right on their website.
But if you do need a little help, there are great resources to help you connect with the right professionals. If you need help organizing your business books before you’re ready to file taxes, our partners at Bench offer online bookkeeping services. And if you’re looking for a certified public accountant (CPA) to help file for you, our partners at Taxfyle will connect you with a licensed CPA.
Getting a State Business Tax Extension
Now that you know how to get an extension for a business tax return from the IRS, it’s important to note that this extension is only for your federal taxes. If you also need a state extension (and you probably do), you’ll need to file a separate extension request with your state.
The Bottom Line
If you need to request an extension for your small business, the IRS makes it easy to do so. There are plenty of reasons why small business owners need extra time to file. Just remember that this is an extension to file taxes, not to pay them.
