Introduction
Starting your own business is exciting — but it also brings new responsibilities, especially when it comes to taxes. In recent years, the United States has seen a record-breaking number of new LLCs and small businesses being created. Yet, many new entrepreneurs have little idea about how taxes work once they become self-employed.
Unlike traditional employees, small business owners no longer have an employer handling tax deductions for income, Social Security, or Medicare. Instead, all those responsibilities fall directly on the business owner. This article breaks down everything you need to know — from types of business taxes to deductions and compliance — so you can manage your finances with confidence.
1. Types of Small Business Taxes
Every entrepreneur should understand the different types of taxes they might face. These can generally be grouped into three main categories:
- Taxes on income you earn
- Taxes on what you buy
- Taxes on what you own
Let’s explore each in detail.
A. Individual Income Tax
Almost all business owners pay individual income tax, except for C corporations. In the United States, the tax system is progressive, meaning your tax rate increases as your income rises.
If you operate as a sole proprietor, single-member LLC, partnership, or S corporation, your business income passes through to your personal tax return. This means you pay income tax based on your personal earnings.
Each year, the IRS updates tax brackets, so it’s important to know where your income falls to estimate your tax liability accurately.
B. Corporate Income Tax
C corporations do not pay individual income tax. Instead, they are subject to a flat federal corporate tax rate of 21%, along with any applicable state corporate taxes, which vary by location.
However, C corporations face double taxation — the company pays taxes on its profits, and when dividends are distributed to shareholders, those individuals pay taxes again on that income. Because of this, it’s essential to consult a tax advisor before choosing to operate as a C corporation.
C. Payroll Taxes
If your business employs workers, you are responsible for payroll taxes, which include:
- Federal income tax withholdings
- Social Security and Medicare contributions (split 50/50 between employer and employee)
- Federal unemployment tax (FUTA)
Employers of W-2 employees bear part of the tax burden, while hiring independent contractors (1099 workers) may reduce payroll-related costs. Still, having dedicated employees often brings long-term benefits beyond tax savings.
D. Self-Employment Taxes
If you’re self-employed — as a sole proprietor, LLC owner, or partner — you must pay self-employment tax.
This covers both the employer and employee portions of Social Security (6.2%) and Medicare (1.45%), totalling 15.3%.
To reduce this burden, some business owners elect to be taxed as S corporations, which allows them to pay themselves a reasonable salary and take the rest as distributions — avoiding self-employment tax on the distribution portion. However, this only makes sense once your net profit exceeds around $60,000 per year.
E. Other Taxes
Sales Tax
If your business sells goods or taxable services, you must collect sales tax from customers and remit it to the state. This tax is paid by consumers but managed by your business.
Excise Tax
Applies to specific products such as alcohol, tobacco, soda, and fuel. If your business operates in one of these industries, you’ll need to account for this additional tax.
Property and Tangible Personal Property Tax
Businesses that own land, buildings, or movable assets like equipment, furniture, vehicles, or machinery may owe property tax or tangible personal property (TPP) tax. Currently, about 43 US states impose TPP taxes.
2. How to Pay Business Taxes
Paying taxes as a small business owner follows four simple steps:
Step 1: Determine What Taxes You Owe
Identify your business structure and corresponding tax obligations:
- Sole Proprietor or Single-Member LLC → File using Form 1040 + Schedule C
- Multi-Member LLC or Partnership → File Form 1065, then report income using Schedule K-1
- S Corporation → File Form 1120-S
- C Corporation → File Form 1120
Each entity type determines how your income is taxed and which forms you must submit.
Step 2: Calculate How Much You Owe
Instead of having taxes withheld automatically (like an employee), you’ll make quarterly estimated tax payments.
To calculate:
- Add your income tax and self-employment tax for the year.
- Divide the total by four to get your quarterly payment amount.
You can use an online calculator or pay 110% of last year’s tax liability to avoid penalties.
Quarterly deadlines typically fall around the 15th of April, June, September, and January.
Step 3: Pay Your Taxes
You can pay directly on the IRS website (irs.gov/payments) using a bank transfer, debit/credit card, or digital wallet like PayPal. Always pay on time to avoid estimated tax penalties.
Step 4: File Your Tax Return
At the end of the year, file your tax return to report income, expenses, deductions, and tax payments. Keeping detailed records throughout the year will make this step much easier.
3. Business Tax Deductions and Credits
One of the biggest advantages of owning a business is access to tax deductions and credits.
A business deduction is any expense that is both:
- Ordinary (common and accepted in your industry), and
- Necessary (helpful and appropriate for your business).
Common Tax Deductions Include:
- Employee wages and benefits
- Payroll taxes
- Travel costs (flights, hotels, meals)
- Office rent and utilities
- Advertising and marketing expenses
- Business supplies and equipment
- Vehicle and machinery purchases
Tax Credits
Unlike deductions, credits reduce your tax bill dollar-for-dollar. Popular business credits include:
- Research & Development (R&D) Tax Credit
- Hiring credits for veterans and disadvantaged employees
- Location-based credits for operating in designated economic zones
By combining deductions and credits, business owners can significantly reduce — and sometimes eliminate — their tax liability.
However, C corporations face double taxation — the company pays taxes on its profits, and when dividends are distributed to shareholders, those individuals pay taxes again on that income. Because of this, it’s essential to consult a tax advisor before choosing to operate as a C corporation.
4. Staying Compliant with the IRS
Tax compliance is not optional — failure to comply can result in penalties, audits, or even loss of LLC protection. To stay compliant, follow these key practices:
Six Tips for Compliance
- Follow State LLC Rules – Each state has its own requirements, such as maintaining records or electing managers.
- Keep Accurate Records – Good bookkeeping makes filing easier and helps if you’re audited.
- Meet Tax Deadlines – File returns and pay taxes on time.
- Comply with Employment Laws – Follow all regulations regarding wages, overtime, and non-discrimination.
- Protect Consumer Privacy – Safeguard customer data and comply with privacy laws.
- Obtain Required Licences & Permits – Make sure you have all local and state authorisations needed for your business.
Failure to follow these steps can lead to fines, audits, or loss of legal status.
5. IRS Receipt Requirements
Every tax deduction you claim must be supported by valid documentation. The IRS requires receipts, invoices, or records to substantiate business expenses. Maintaining a well-organised digital or physical filing system ensures that your deductions hold up under scrutiny and saves you stress during tax season.
Conclusion
Managing small business taxes may seem intimidating at first, but once you understand the basics — what to pay, when to pay, and how to stay compliant — it becomes manageable.
By learning about income taxes, deductions, credits, and proper bookkeeping, you can reduce your tax burden, protect your business, and focus on growth.
Running a business isn’t just about making money — it’s about managing it wisely. And understanding taxes is one of the smartest steps any entrepreneur can take toward lasting success.
