1. Gather your records for tax filing 

At the most basic level, you need to file your tax return each year through the IRS to figure out your tax liability. As a business, you might have to pay taxes that include:


  • Estimated tax: Quarterly federal and state tax payments made throughout the year that aren’t subject to federal tax withholding. 
  • Self-employment tax: Social Security and Medicare taxes for independent contractors and self-employed individuals. 
  • Sales tax: Taxes collected from taxable goods and services. 
  • Property tax: Taxes paid on the value of a business property. 
  • Excise tax: Taxes on specific goods or services. 
  • Employment taxes: Social Security, Medicare, federal income tax withholding, and Federal Unemployment Tax Act (FUTA) taxes.
What taxes do I have to pay as a small business? As a small business owner, you may be required to pay taxes like estimated tax, self-employment tax, sales tax, property tax, excise tax, and employment taxes.

For all these taxes, detailed records of business expenses you pay throughout the year can help lower your taxable income. You’ll need to get your company records together to report your business income and qualified business expenses.


This means gathering supporting documents for payroll, sales, purchases, and other qualified business expenses. Some of the small business documents you should gather when preparing your taxes include:


  • Invoices
  • Paid and outstanding bills
  • Canceled checks
  • Deposit slips 
  • Sales slips 
  • Cash register tapes
  • Credit card statements
  • Bank account statements
  • Employment tax records
  • Year-end payroll reports 


Using tax preparation or financial software to track expenses and transactions throughout the year is often easier than trying to gather all the info right before your due date.

2. Know what IRS forms you need to file 

The types of IRS forms you’ll need to fill out to file small business taxes depend on your business structure. 


Here are the small business tax forms you might need to file your return: 


  • Sole proprietorship: If you’re a sole proprietor, use a Schedule C IRS file form. Individuals need to attach their Schedule C to their personal tax returns. 
  • Partnerships: Partnerships file their business tax returns using Form 1065. Partners and the partnership need to report business activity to the IRS. A partnership sends Schedule K-1 out to ‌partners.
  • Corporations: If you’re a corporation, you must use the corporate tax return Form 1120 (or Form 1120S if you’re in an S-corporation structure).
  • Limited liability companies (LLCs): LLCs use a variety of forms, conditional on how the business elects to be taxed. Typically, most multimember LLCs default to be treated as a partnership. If the LLC is a single-member LLC, then the entity is taxed the same as a sole proprietorship. 

If you want your business to be taxed as a C corporation, then you use Form 1120. If you want your LLC to elect to be treated as an S corporation, timely file Form 2553.

3. Fill out your small business tax forms

When filling out your small business tax forms, carefully follow each step and provide accurate information. If you’re filing using Schedule C, the form is a bit less complex, as it is only two pages. 

Form 1065, Form 1120, and Form 1120S are more extensive and might require a bit more time to fill out. Be prepared with all of the required information, and have your supporting documents handy before filling out your form. Using accounting software can help you stay organized.

4. Know the small business tax deadlines

During some tax years, the due date for sending in your personal income tax return or small business tax return falls on a holiday or a weekend. If that occurs, the new tax deadline is the next business day.

Here are the key tax filing dates and deadlines you’ll want to be aware of: 

  • March 15: For partnerships and multimember LLCs that file a Form 1065 with the federal government and give out a Schedule K-1 to partners, and S-corps filing Form 1120-S.
  • April 15: For sole proprietors or single-member LLCs filing Schedule C.
  • April 15: Corporations with a fiscal year that ends on December 31, submitting Form 1120.
  • April 15: If your fiscal year ends on a date other than December 31, your tax return deadline is the 15th day of the fourth month after the end of your tax year.

5. File for a business tax extension, if needed

Need to push back your deadline? You can file for a business tax extension to send your taxes in later with Form 7004. This form grants a six-month extension to file, though it doesn't provide extra time to pay. Get the extension filed before the deadline so you don’t have to pay penalties. 

The tax extension deadlines for small businesses are: 

  • March 15: Deadline for partnerships and S corporations
  • April 15: Deadline for sole proprietors (extension form is Form 4868 for individual tax returns) and C corporations.

If you don’t file an extension and miss your tax filing deadline, you might face the Failure to File Penalty. The penalty is 5% of your unpaid taxes for each month or part of the month that your small business tax return is late.


Tip: State tax and extension deadlines vary by location. Research your local tax guidelines and due dates early in the filing process.


6. File small business taxes

If you’re concerned about filing your taxes correctly, it’s worth enlisting the help of a licensed tax professional. With the help of a pro, you can ensure that you: 

  • Are compliant with tax laws. 
  • Make the appropriate tax payments.
  • Understand your tax refund.

Note that e-filing is easier and faster than mailing, meaning you can get your tax refund faster too. The IRS offers many different filing options for small businesses to choose from.

7. Stay on top of small business tax payments

Many businesses have to make estimated tax payments throughout the year. You're responsible for making estimated tax payments each quarter if:

  •  You’re a sole proprietor, partnership, or S corporation and expect to owe over $1,000 on your tax return, or 
  • You're a corporation and expect to owe over $500 or more when the return is filed. 

You can pay your estimated taxes on the IRS website, from your mobile device using the IRS2Go app, or by mailing in Form 1040-ES. Not making estimated tax payments or underpaying your taxes could result in a penalty from the IRS. 

You still have to file an annual small business tax return and calculate your tax liability for the year, even after paying quarterly taxes. If you didn’t pay enough through your quarterly tax payments, you’ll be responsible for paying the remainder when you file your tax return. 

Though you might still owe money at the end of the year, making quarterly small business tax payments can help lower your end-of-year tax bill. 

Maximize your small business tax deductions

Small business owners can help lower their tax bill by maximizing deductions. Small businesses are allowed “ordinary and necessary” tax deductions that can help reduce taxable income. 

A lower taxable income means you and your business might owe less money during the tax year. Some examples of small business tax deductions include business meals, travel expenses, home office costs, and vehicle use. It's important to keep a detailed record of all your small business tax deductions

Here are some tips for keeping records: 

  • Hold onto receipts from business expenses.
  • Write out why each purchase counts as a business expense.
  • Organize purchases by date.
  • Note the amount paid for every business expense and payment method.

If the IRS audits a business’s write-offs, these records can help avoid penalties and fines.
