C-Corp vs. S-Corp vs. LLC: Tax Advantages Explained

April 7th, 2026

Starting a business is an exciting journey. One of the first decisions new business owners need to make is choosing the right business structure. This choice will impact your taxes, personal liability, management responsibilities, and even how you can raise capital. Choosing the best business structure for your situation depends on the size and type of the business, its growth potential, how it will be managed, and how the owners want to be taxed.

Anyone considering starting a business should seek advice from a qualified tax professional. The experienced accounting and tax professionals at Gudorf Tax Group, LLC, can evaluate your situation, provide advice and guidance on which business structure is best for you, and prepare the documents necessary to create your new business entity.

What Are the Main Types of Business Ownership Structures?

Three of the most common business structures are the C-Corp, the S-Corp, and the LLC. Each business structure has advantages and drawbacks, and there is nothing inherently “better” about one versus the other. The designations describe how the company is taxed and the rules it must follow to remain compliant with the IRS.

In general, C-Corps tend to be larger companies, while S-Corps and LLCs tend to be smaller businesses and sole proprietorships. However, many factors can affect a business’s strategic choice of entity.

What Is a C-Corporation?

A C-Corp, named for its inclusion in subchapter “C” of the IRS Code, is the most formal business structure. It is best suited for larger businesses and those seeking outside investment. A C-Corp is an independent legal entity, owned by its shareholders, that offers owners the strongest liability protection.

C-Corps are subject to “double taxation,” which means the corporation is taxed at the corporate tax rate of 21%. Dividends and profits to the company are passed on to shareholders and are taxed a second time as personal income.

What Is an S-Corporation?

An S-Corp, named after its inclusion in subchapter S of the IRS Code, is a business tax designation that provides “pass-through taxation” to company shareholders. S-Corps provide liability protection like C-Corps, but are not subject to double taxation. Taxable revenue is not taxed at the federal level, but instead “passes through” to the owners’ and shareholders’ personal tax returns. Business owners and shareholders may pay up to 13.3% in state and local income taxes, plus 10% to 39.6% for federal personal income taxes on earnings or profits.

What Is an LLC?

A Limited Liability Company, or LLC, is a popular choice for smaller businesses. It is comparatively easier to establish and still protects the owners’ personal assets from business liabilities. By default, LLCs are subject to pass-through taxation, where profits and losses are reported on the owners’ personal tax returns. However, an LLC can elect to be taxed as a C-Corp or an S-Corp.

Tax Advantages and Drawbacks of C-Corp, S-Corp, and LLC

Choosing the right business structure is one of the most important decisions new business owners will make. A C-Corp, S-Corp, and LLC each shield business owners from personal liability, and each business structure provides distinct management, compliance, and tax requirements.

C-Corp

C-Corps offer many tax advantages. However, this business structure is the most complicated to set up and has the most stringent tax and reporting requirements.

Benefits:

  • Lower corporate tax rate
  • Profits that stay in the company and are not distributed are not taxed
  • Health insurance, retirement plans, and other employee benefits are not taxed

Drawbacks

  • Double taxation
  • Business losses cannot offset personal income

S-Corp

An S-Corp avoids double taxation, as owners report business income, losses, deductions, and credits on their personal income tax returns, which can provide significant tax savings. However, S-Corps can issue only a single class of stock and strict eligibility requirements apply.

Benefits:

  • Pass-through taxation
  • Shareholders classify income as salary, which is subject to payroll taxes, and distributions, which are not subject to the self-employment tax
  • Business losses can be used to offset personal income

Drawbacks

  • Strict eligibility requirements
    • Up to 100 shareholders
    • U.S. citizens and legal residents only
    • One class of stock
  • All profits must be distributed proportionally to owners
  • Many employee benefits are taxable

LLC

An LLC offers the liability protection of a corporation but with simpler and more flexible management requirements. There are few ownership restrictions and owners choose how they wish to be taxed.

Benefits

  • Flexible tax classification (choose C-corp, S-Corp, partnership, or sole proprietorship)
  • Profit distribution does not need to match ownership percentages
  • Losses can be used to offset personal income

Drawbacks

  • All profits are subject to self-employment tax
  • The company still must comply with S-corp requirements if selected
