When starting a business, determining its tax classification for U.S. income tax purposes is one of the most critical decisions. This classification not only dictates how the entity is taxed but also affects compliance and long-term financial strategy. Business entities can generally be classified as flow-through entities or corporations:
- Flow-through entities: Income, losses, and credits flow directly to the owners, who are taxed at the individual level regardless of whether profits are distributed.
- Corporations: Income is taxed at both the entity level and again at the owner (shareholder) level when distributions occur.
Among corporations, some are automatically classified as corporations under U.S. tax law. These are known as Per Se corporations, which are not eligible to elect a different tax classification. This article explores the concept of Per Se corporations, their historical context, and their significance under modern tax regulations.

The Evolution of Entity Tax Classification
Before 1997, determining a business entity’s tax classification was governed by the Kintner regulations. These regulations listed six characteristics that defined a corporate venture, including:
- Associates.
- An objective to carry on business and divide gains.
- Limited liability for owners.
- Centralized management.
- Continuity of life.
- Free transferability of ownership interests.
The Kintner regulations aimed to evaluate whether an entity possessed enough corporate characteristics to be classified as a corporation. However, this system was fraught with complexity and subjectivity. Determining whether an entity met the criteria often led to inconsistent results, especially with the rise of hybrid entities such as limited liability companies (LLCs) and limited liability partnerships (LLPs), which blurred the lines between corporations and flow-through entities.
To address these challenges, the IRS issued Notice 95-14, signaling an intention to simplify the classification process. This effort culminated in the Check-the-Box (CTB) regulations, finalized in 1997, which established clear rules for electing or defaulting to specific classifications under Internal Revenue Code (IRC) Section 7701.
Check-the-Box Regulations
The CTB regulations revolutionized the entity classification process by allowing certain entities to elect their tax classification. These rules apply to eligible entities, which are not automatically classified as corporations.
How It Works
- Eligible Entities: These entities can choose to be classified as a:
- Corporation (association).
- Partnership (if there are two or more owners).
- Disregarded entity (DRE), if there is a single owner.
- Default Classifications:
- A domestic eligible entity defaults to a partnership if it has two or more members or a DRE if it has a single owner.
- For foreign eligible entities, default classifications vary based on ownership structure and liability status.
- Making an Election: Eligible entities must file Form 8832 (Entity Classification Election) to choose a classification other than the default. The election is effective as of the date specified on the form, provided it falls within the allowable retroactive or forward-looking period.
Per Se Corporations: Automatic Classification
Some entities, however, are excluded from the flexibility of the CTB regulations. These are Per Se corporations, which are automatically classified as corporations for U.S. tax purposes and cannot elect a different classification.
What Defines a Per Se Corporation?
Per Se corporations include:
- Entities formed under federal or state laws that explicitly define them as corporations, joint-stock companies, or associations.
- Insurance companies.
- State-chartered banks.
- Entities owned by state or local governments.
- Business entities taxable as corporations under provisions of the IRC, other than IRC Section 7701.
- Specific types of foreign entities listed in Treas. Reg. 301.7701-2(b)(8).
Foreign Per Se Corporations
The IRS has enumerated certain types of foreign entities that are always classified as corporations under U.S. law. For example, many foreign joint-stock companies and publicly traded corporations are on this list.
Tax Implications of Per Se Corporations
The automatic classification as a corporation has significant tax implications:
- Double Taxation: Like other corporations, Per Se corporations face double taxation. Income is taxed at the corporate level and again when distributed to shareholders.
- Compliance: Per Se corporations must adhere to corporate tax filing requirements, including submitting Form 1120 (U.S. Corporation Income Tax Return) and potentially other international forms if the entity is foreign.
- No Flexibility: Unlike eligible entities, Per Se corporations cannot choose a flow-through status, which limits tax planning options.
Domestic vs. Foreign Entity Rules
Domestic Entities
For domestic entities, classification is straightforward:
- Eligible entities may default to a partnership or DRE or elect corporate status.
- Per Se corporations are automatically classified as corporations, without eligibility for elections.
Foreign Entities
Foreign entities are subject to different rules:
- Eligible foreign entities default to:
- A partnership if they have two or more owners and at least one owner does not have limited liability.
- A corporation if all owners have limited liability.
- A DRE if they have a single owner without limited liability.
- Per Se foreign corporations are those explicitly listed in the Treasury regulations.
These differences mean that a foreign entity might be classified differently in its home country than it is for U.S. tax purposes. This discrepancy can lead to hybrid entities (e.g., taxed as flow-throughs in the U.S. but as corporations abroad) or reverse hybrid entities (e.g., taxed as corporations in the U.S. but as flow-throughs abroad).
Making and Changing Elections
Eligible entities can make an election by filing Form 8832. The election must specify the desired classification and its effective date. However, once an entity changes its classification, it cannot elect again for 60 months, unless there is a significant ownership change or IRS approval is obtained.
