Understand the types of business taxes

All businesses must pay certain federal and state taxes. This depends on your type of business entity (sole proprietorship, S corporation, or C corporation), whether you have employees, and if you sell specific products or services. Let’s take a brief look at the most common types of small business taxes:

  • Income tax: Taxes paid on the profits your company makes

  • Estimated taxes: Quarterly tax payments

  • Self-employment taxes: Social security and Medicare tax payments for self-employed individuals

  • Employment taxes: Social security, Medicare, and federal unemployment taxes for companies with employees

  • Excise tax: Additional taxes on specific goods and services

Complete the necessary tax forms

Your business structure determines which tax forms you need to submit. You’ll need to report profits, losses, deductions, and credits to the IRS. Some of the most common tax forms include:

  • Schedule C: Sole proprietors should use this form to report profit and loss and file it along with their Form 1040.

  • Schedule K-1: Owners of S corporations and partnerships and members of multi-owner LLCs (all pass-through entities) must file a Schedule K-1 to report income.

  • 1099-NEC or 1099-MISC: Business owners and independent contractors use this form to report self-employment income.

  • Form 1120: C corporations must use this form to report income.

  • Form 1120-S: S corporations must file this form separately from their personal income tax return to report their income.

  • Form 1065: Partnerships file this information return to report their income, gains, losses, deductions, credits, etc.


Keep a calendar of tax deadlines

Business owners must stay on top of tax payment and filing due dates to avoid fines and penalties. Keep track easily by using a calendar with the following important dates:

  • January 31: Business owners must send W-2s to their employees and 1099s to their independent contractors. This is also the deadline for sending copies of these tax documents to the IRS.

  • February 28: Companies must file their information return using a 1099 or 1096 on paper. (If you file electronically, the deadline is April 1.)

  • March 15: Deadline for partnerships, S corporations, and multi-member LLCs to file their return.

  • April 15: Deadline for single-member LLCs, sole proprietors, and C corporations (that follow the standard calendar year for accounting) to file their return.

  • April 15: First estimated tax payment due

  • June 15: Second estimated tax payment due

  • September 15: Third estimated tax payment due

  • January 15: Final estimated tax payment due


When these dates fall on a weekend or holiday, returns and payments are due the following business day. You can use Form 7004 to file an automatic 6-month extension if you need one.
