Choosing between a corporation (Inc.) and a limited liability company (LLC) affects how your business is taxed, how profits are shared and how much paperwork you need. While both LLCs and corporations can elect corporate tax treatment, corporations are structured by default as separate tax entities, which can make it easier to retain earnings (reinvest profits) rather than passing them through to owners as taxable income each year. LLCs, by comparison, are default pass-through entities, meaning profits are typically distributed and taxed on the owners’ personal returns unless the LLC elects corporate taxation. A financial advisor or tax professional can help you choose the structure that fits your goals.

Inc. vs. LLC: Tax Differences

The primary distinction between an Inc. and an LLC lies in how each is taxed and how income flows through the business to its owners. While both structures offer liability protection, their tax obligations and flexibility vary significantly.

LLC Taxation

Two business owners discussing differences between forming an Inc. or an LLC.

An LLC is typically taxed as a pass-through entity. This means the business itself does not pay federal income tax. Instead, profits and losses pass through directly to the owners. The owners, also called members, report this as income on their personal tax returns. By default:

However, LLCs can also elect to be taxed as an S corporation or a C corporation by filing IRS Form 2553 or Form 8832, respectively. This flexibility allows business owners to optimize their tax strategy based on their income level, business expenses and growth plans.

Corporation (Inc.) Taxation

  • A C corporation is taxed as a separate legal entity. It pays corporate income tax on its profits, and shareholders also pay personal taxes on dividends. This is known as double taxation.
  • An S corporation, while still a corporation, is a pass-through entity for tax purposes. Income is reported on the shareholders’ personal tax returns, avoiding double taxation, but with more restrictions on ownership and profit distribution.

Corporations must file a corporate tax return (Form 1120 or 1120-S) and may face additional compliance and administrative costs.
