Types of Business Taxes

Navigating the landscape of business tax obligations can be daunting. Let’s break down the different types of taxes that may apply to your business, ensuring you stay compliant and make informed decisions.

Income Tax

All businesses, with the exception of partnerships, need to file an annual income tax return. The form used depends on the business structure:

  • Corporations file using Form 1120.
  • S Corporations file Form 1120-S, passing income directly to shareholders to avoid double taxation.
  • Partnerships do not pay taxes at the business level but must submit an informational return on Form 1065.

Understanding which form applies to your business structure is crucial for meeting your tax obligations.

Estimated Tax

If your business is not withholding taxes on its income, you’ll likely need to make quarterly estimated tax payments. This applies to many self-employed individuals, corporations, and partners in partnerships. Using Form 1040-ES for individuals or Form 1020-W for corporations, you can stay on top of these payments to avoid underpayment penalties.

Self-Employment Tax

This tax covers Social Security and Medicare for individuals who work for themselves. If your net earnings exceed $400, you need to file Schedule SE (Form 1040) to calculate your due contributions. These contributions provide critical benefits like retirement, disability, and Medicare.

Employment Taxes

If you employ others, your business must handle employment taxes, which include:

  • Withholding taxes from employee wages for federal income tax.
  • Social Security and Medicare taxes, split between the employer and the employee.
  • Federal unemployment (FUTA) tax, paid entirely by the employer.

These taxes are primarily reported quarterly using Forms 941 or 940 for FUTA.

Excise Tax

Certain businesses may also be subject to excise taxes, which are taxes on specific goods, services, and activities. This could include environmental fees, communication services, and more. Depending on your specific business activities, you may need to file:

  • Form 720 for quarterly federal excise tax returns.
  • Form 2290 for heavy highway vehicle use tax.
  • Form 730 for wagering.
  • Form 11-C for occupational tax and registration return for wagering.

Each form corresponds to different excise activities, so identifying which, if any, apply to your business is essential.

By understanding the various forms and types of taxes, from income to excise, you can better manage your business’s obligations and avoid potential penalties. Always consult with a tax professional to ensure you’re fully compliant and taking advantage of all possible deductions and credits. This proactive approach will not only keep you compliant but also optimize your business’s financial health.

Understanding Your Tax Rate

Understanding your business tax rate is crucial for effective financial planning and compliance. Let’s break down the key components: Corporate Tax Rate, Pass-Through Entities, and Deductions and Credits.

Corporate Tax Rate

The corporate tax rate in the United States is a flat 21%. This rate was established by the Tax Cuts and Jobs Act (TCJA) signed into law in 2017. Businesses operating as C corporations are subject to this rate, which applies to their profits—revenue minus allowable expenses. While the federal rate is flat, state taxes can vary, adding an additional layer to the tax obligations of a corporation.

Pass-Through Entities

Unlike C corporations, pass-through entities such as S corporations, partnerships, and sole proprietorships, do not pay taxes at the business level. Instead, profits and losses are passed through to the owners’ personal tax returns, and they are taxed at their individual tax rates. This structure avoids the double taxation typically seen in C corporations—once at the corporate level and again at the individual level on dividends.

S corporations combine the legal protection of a corporation with the tax benefits of a pass-through entity. However, they must adhere to certain restrictions, including limits on the number of allowable shareholders.

Deductions and Credits

Businesses can reduce their taxable income through various deductions and credits. Deductions lower the amount of income that is subject to tax, while credits reduce the tax itself. Common deductions include:

  • Business expenses: These are costs necessary for operation, such as rent, utilities, and payroll.
  • Home office deduction: If you use part of your home regularly and exclusively for business activities, you may be able to deduct expenses related to that portion of your home.
  • Depreciation: This allows businesses to write off the cost of significant purchases like equipment and furniture over time.

Tax credits, on the other hand, are incentives that directly lower your tax bill. For example, the Research and Development (R&D) Tax Credit offers a dollar-for-dollar tax reduction to businesses investing in innovation.

Businesses can also take advantage of specific state and local tax incentives, which may offer additional credits, deductions, or lower tax rates to encourage economic development.

By understanding these key aspects—corporate rates, pass-through taxation, and available deductions and credits—you can better navigate the complexities of business taxes. This knowledge ensures compliance and optimizes your company’s financial strategy.

In the next section, we will delve into common business tax deductions, helping you identify further opportunities to reduce your taxable income.

Common Business Tax Deductions

Understanding how to leverage business tax deductions can significantly reduce your taxable income and enhance your financial strategy. Let’s explore some of the most common deductions that small business owners should consider.

Cost of Goods Sold (COGS)

COGS is a critical deduction for businesses that sell products. It includes the direct costs associated with the production of goods sold by a company. This might include the cost of the materials and labor directly used to create the product. Properly accounting for COGS can lower your taxable income, as it is subtracted from your gross receipts to determine the gross profit for your business.

Business Expenses

Business expenses are the everyday costs of running a business, and they must be both ordinary (common in your business field) and necessary. These include:

  • Travel: Costs related to business travel, such as flights and hotels, are deductible. Only 50% of meal expenses are deductible.
  • Advertising and Marketing: Expenses incurred in promoting your business, including digital advertising and print media.
  • Insurance: Premiums paid for business insurance are fully deductible.

Keeping detailed records of these expenses is crucial for accurate reporting and maximizing your deductions.

Home Office Deduction

For those who use a part of their home exclusively for business purposes, the home office deduction is a valuable opportunity to reduce taxable income. You can choose between the simplified option, which multiplies the square footage of your office by $5 for up to 300 square feet, or the regular method, which involves calculating the percentage of your home used for business and applying that to home-related expenses.


Depreciation is a method of allocating the cost of tangible assets over their useful lives and is a way of deducting the wear and tear of property used in your business. Commonly depreciated items include buildings, vehicles, and equipment. The IRS allows various methods for depreciation, such as:

  • Section 179: This allows businesses to deduct the full purchase price of qualifying equipment or software within the tax year.
  • Bonus Depreciation: Typically used to accelerate depreciation, this can be applied to new assets that have a useful life of 20 years or less.

These deductions not only lower your immediate tax liability but also spread the cost of expensive assets over their operational life, aiding in long-term financial planning.

By understanding and applying these common business tax deductions, you can significantly reduce your taxable income, ensuring that your business retains more of its hard-earned money. This strategic approach to deductions is essential for effective tax planning and financial management.

Navigating State and Local Taxes

Understanding the tax landscape at the state and local level is crucial for small business owners. Different states can have vastly different tax implications for your business, which can significantly affect your bottom line. Let’s delve into the business tax climates of Missouri and Illinois to help you navigate these waters.

Missouri Business Tax Climate

Missouri offers a very business-friendly tax environment, which is reflected in its ranking by the Tax Foundation. The state is ranked 12th overall for its business tax climate, with a particularly favorable corporate tax rate, ranking 3rd in the nation.

Corporate Income Tax:
Missouri charges a corporate income tax of only 4% on Missouri taxable income, which is calculated based on a market-based apportionment model focusing solely on sales. This lower rate can be highly advantageous for businesses with substantial sales in Missouri.

Sales and Use Tax:
The state levies a 4.225% sales tax on the purchase price of tangible personal property and certain services. Local sales taxes also apply but vary by jurisdiction, which means businesses need to be aware of the specific rates in their operating areas.

Property Tax:
In Missouri, commercial and industrial property is assessed at 32% of its market value, with residential property at 19%. These rates are combined with local district rates and a minimal state tax of 0.03%, making Missouri’s property tax environment relatively moderate compared to other states.

Illinois Business Tax Climate

In contrast, Illinois presents a more challenging tax environment for businesses, ranking 36th overall. The higher corporate and other taxes can impact business operations more significantly.

Corporate Income Tax:
Illinois imposes a 9.5% tax on corporate income, which includes a 7% state income tax and a 2.5% personal property replacement tax. This higher rate can be a significant burden, especially for businesses with high taxable incomes.

Franchise Tax:
Though Illinois has begun phasing out its franchise tax, with complete repeal expected after 2023, businesses currently face an initial franchise tax of 0.15% of paid-in capital and an annual tax thereafter. This phase-out is something businesses should monitor closely as it progresses.

Sales and Use Tax:
The state sales tax rate stands at 6.25% on the purchase price of tangible personal property and selected services. Like Missouri, local sales taxes also apply and vary by jurisdiction. Additionally, Illinois imposes a 1% tax on qualifying food, drugs, and medical appliances, adding complexity to tax calculations for businesses in these sectors.

Property Tax:
Real property in Illinois is assessed at 33.3% of market value, with no tax on personal property. The high assessment rate can lead to significant property tax liabilities, particularly in areas with high local tax rates.

Understanding these differences in tax climates can help you make informed decisions about where and how to operate your business. Whether you’re considering expanding into new states or optimizing your existing operations, being aware of the specific tax obligations in Missouri and Illinois is essential. This knowledge not only helps in compliance but also in strategic planning and financial forecasting.

In the next sections, we will address some frequently asked questions about business taxes to further clarify this complex subject.

Frequently Asked Questions about Business Taxes

Navigating the complex world of business tax can be challenging. Here, we answer some common questions that small business owners might have.

What qualifies as a business for taxes?

A business for tax purposes is any activity carried out with the reasonable expectation of earning a profit. The IRS considers several factors to determine if an activity qualifies as a business, including:
Consistency of activity: Regular and continuous involvement in the activity.
Profit motive: The primary goal is to make a profit.
Transactions and activity: Engaging in activities typical for businesses in your industry.

This includes everything from large corporations to small home-based businesses. If you’re regularly selling goods or services, it’s likely that the IRS considers your activities a business.

How much is IRS business tax?

The amount of tax a business owes to the IRS depends on several factors, including the business structure, the amount of income earned, and allowable deductions and credits. For example:
Corporations are taxed at a flat federal rate of 21% on their profits.
Pass-through entities, such as S corporations, partnerships, and sole proprietorships, don’t pay taxes at the business level. Instead, profits are passed through to the owners’ personal tax returns and taxed at individual rates.

It’s essential to calculate your taxable income accurately by considering all business revenues, costs of goods sold, and other deductible expenses.

What is the tax rate for small business in Missouri?

Missouri offers a favorable tax environment for small businesses:
– The corporate income tax rate in Missouri is 4% of Missouri taxable income, which is relatively low compared to many other states.
Sales and use tax rates start at 4.225% at the state level, with additional local rates that vary by jurisdiction.
– Missouri does not impose a franchise tax, which is a benefit for businesses operating within this state.

For small businesses operating as pass-through entities, the tax rate will depend on the income levels of the owners, as this income is passed through to their individual tax returns.
