What Is IRS Form 720? Quarterly Federal Excise Tax Return

If you're running a business in the U.S., especially one that deals with specific goods or services like fuel, airline tickets, or indoor tanning, chances are you’ve come across IRS Form 720. It may not be as famous as Form 1040 or W-2, but it’s still incredibly important for those it applies to. So, If you still wondering what is Form 720, Let’s talk in detail.

What Is Form 720?

Form 720, officially titled the “Quarterly Federal Excise Tax Return,” is used by businesses to report and pay federal excise taxes. These taxes apply to certain products and services, not to your regular income or payroll. Think of it this way: while income tax is based on what you earn, excise tax is based on what you sell or offer especially if it falls into specific categories that the IRS monitors closely.

Form 720 is used for the IRS’s way of tracking and collecting excise taxes from companies that deal with goods like gasoline, tobacco, air transportation, vaccines, and even services like indoor tanning. If your business touches any of these areas, you’ll likely need to file this form every quarter.

Why Does the IRS Have Excise Taxes?

Before we discuss further, it helps to understand the why behind this form. Excise taxes are sometimes called “sin taxes” or “luxury taxes” because they’re placed on products that either harm the environment, affect health, or are considered non-essentials.

For example, fuel taxes help pay for highway maintenance. Taxes on tobacco and alcohol? They partly go toward public health initiatives. So, when you ask what is Form 720 really all about it’s not just a paperwork requirement. It’s tied to how the government funds specific programs and tries to steer consumer behavior.

Who Needs to File Form 720?

Now here's where many small business owners get confused. You don’t need to file Form 720 just because you run a business. You only need it if your business is responsible for collecting and remitting excise taxes. This might include:

• Fuel distributors
  
  

• Airline companies
  
  

• Manufacturers of certain medical devices or vaccines
  
  

• Tanning salon owners
  
  

• Producers or importers of alcohol and tobacco products
  
  

• Large truck and trailer owners (yes, there’s even a section in Form 720 for highway use tax)
  
  

If you're unsure whether you need to file, take a closer look at the IRS's instructions for Form 720, or better yet, talk to a tax professional. But if you deal in these areas even occasionally, it’s worth investigating.

Structure of Form 720

Let’s discuss in detail what is Form 720 made up of. It’s not a one-size-fits-all form you only fill out the parts that apply to your business.

The form is divided into several sections:

1. Part I – Environmental Taxes (like ozone-depleting chemicals and crude oil)
   
   

2. Part II – Communications and Air Transportation Taxes
   
   

3. Part III – Fuel Taxes
   
   

4. Part IV – Retail Taxes (like those on heavy trucks and trailers)
   
   

5. Schedule A – Used to calculate net tax liability
   
   

6. Schedule T – Required if you’re dealing with certain fuels
   
   

7. Schedule C – For claiming credits that can reduce your tax
   
   

For example, if you run a tanning salon, you’ll only need to fill out the line in Part II that relates to indoor tanning services. No need to worry about fuel or vaccines unless they’re part of your business.

Common Excise Tax Categories (Reported on Form 720)

To help you better understand what is Form 720 used for, here’s a quick breakdown of some common excise tax categories and examples of taxable items or services:

When and How to File Form 720

The “quarterly” part of the form’s name isn’t just for show. Businesses must file Form 720 four times a year:

• Q1: January – March (due April 30)
  
  

• Q2: April – June (due July 31)
  
  

• Q3: July – September (due October 31)
  
  

• Q4: October – December (due January 31 of the following year)
  
  

You can file Form 720 either by mail or electronically. The IRS encourages e-filing because it’s faster and reduces the chance of errors. If you’re still doing paper filing, you’ll mail it to the IRS based on your state. Double-check the IRS’s mailing addresses since they can change from year to year.

Common Mistakes to Avoid

Filing Form 720 isn’t difficult, but some common mistakes can make it a headache. One of the biggest issues is filling out the entire form when only a few sections apply this can lead to confusion and errors. Many businesses also miss the quarterly deadlines, which can trigger penalties. Another overlooked detail is the availability of credits; if you returned taxable goods or made adjustments, Schedule C could help reduce what you owe. 

Lastly, incorrect tax calculations are a frequent problem, especially if your business deals with multiple taxable products or services. In the end, it’s not the form itself that’s tricky, but the context and complexity of your specific tax responsibilities.

Real-Life Examples to Bring It Home

Sarah owns a chain of tanning salons in Florida. Every time a customer pays for a tanning session, Sarah is responsible for charging a 10% federal excise tax on the price. She collects this from the customer and must report it on Form 720 every quarter.

Mike, who distributes diesel fuel. He collects federal fuel taxes at the pump and needs to report and pay them using Form 720 as well.

Both Sarah and Mike may have very different businesses, but they’re bound by the same IRS requirement. And knowing what is Form 720 helps them stay compliant and avoid hefty fines.

What Happens If You Don’t File Form 720?

Failing to file or pay your excise taxes on time can lead to penalties and interest. The IRS doesn’t take this lightly. You may face:

• A failure-to-file penalty (typically 5% per month up to 25%)
  
  

• A failure-to-pay penalty (0.5% per month until you pay in full)
  
  

• Interest on the unpaid amount
  
  

So even if you're unsure whether your business qualifies, it’s better to check early. Filing late, even if you owed nothing, could still get you into trouble.

Do You Need a Tax Pro to File Form 720?

Not always. If your business only handles one type of excise tax, like tanning or highway use, and your operations are pretty straightforward, you might be able to handle it on your own. Many tax software programs support Form 720 now, making it easier than ever. However, if you deal with multiple taxable goods or you're not confident in reading IRS instructions, getting professional help can save you from costly mistakes.
