Small Business Tax Rates as of 2024


Figuring out your taxes as a small business owner can feel like a guessing game since there isn’t a single tax form or single tax rate for all businesses. Not only do you need to plan around your future uncertain income — you also need to keep track of changing federal laws. As you get ready for another tax season, these strategies can help you determine your small business tax rates.

What Is the Federal Small Business Tax Rate?

Your tax rate depends on the structure of your business.

C Corporations must pay the flat corporate tax rate, which is currently 21% as of 2024. Sole proprietorships, partnerships, and S corporations are considered pass-through entities, so their incomes are taxed at the business owner’s personal tax rate, which is between 10% to 37% (see chart below for exact numbers). Limited liability companies (LLCs) have the option to pay taxes as a corporation or as a pass-through entity.

How to estimate your 2024 small business taxes:

One of the tax challenges that small business owners face is that they don’t know what their revenue will look like in a given year, and revenue helps determine the tax rate. Despite this tax rate uncertainty, the IRS still expects you to send in taxes throughout the year.

For C-corporations, you can simply apply the current corporate tax rate of 21% to your company’s taxable income. Let’s say your C-corp has a taxable income of $100,000. To calculate the tax due using the 2024 corporate tax rate of 21%:

Tax Due = Taxable Income x Tax Rate

Tax Due = $100,000 x 21%

Tax Due = $21,000

Unlike C-corporations, where the business itself is taxed separately from the owners, pass-through business owners basically include their business earnings on their personal tax forms and pay 10%-37% taxes depending on their overall personal income.

How to reduce small business taxable income:

A small business owner can reduce their taxable income by taking advantage of tax credits and exploring different deductibles:

  1. Deductible Business Expenses: Deduct business expenses such as office supplies, marketing costs, and travel expenses. Make sure to keep all receipts.
  2. Home Office Deduction: If you use a portion of your home exclusively for your business, you may qualify for a home office deduction, allowing you to deduct some of your mortgage or utilities.
  3. Retirement Savings: Contributions to retirement plans such as 401(k) or Simplified Employee Pension (SEP) are tax deductible.
  4. Section 179 Deduction: Use Section 179 to deduct the costs of certain business properties like equipment or heavy machinery.
  5. Business Tax Credits: Explore business tax credits such as the Work Opportunity Tax Credit (WOTC) for hiring certain employees or the Small Business Health Care Tax Credit for providing employees with health coverage.
  6. Consult a Professional: Seek advice from a professional tax accountant who can provide personalized guidance based on your business structure, industry, and other factors.

Keep in mind that tax laws are always changing so it is crucial to stay up to date with the latest regulations or consult with a tax professional to ensure compliance and maximized deductions.
