What Is Piercing the Corporate Veil?
Last reviewed: June 2026
Piercing the corporate veil is a legal doctrine that allows a court to set aside the limited liability protection of a corporation or LLC and hold the owners personally liable for the entity's debts. Limited liability is the fundamental benefit of incorporating — owners are not personally responsible for the entity's obligations. But this protection is not absolute.
Courts pierce the veil when the corporate form has been so abused that respecting it would sanction a fraud or injustice. The requirements for piercing vary by state but typically involve showing that there was such unity of interest and ownership between the owners and the entity that the entity's separate personality no longer exists, and that adhering to the separate legal existence would sanction a fraud or promote injustice.
Frequently Asked Questions
What conduct leads to piercing the corporate veil?
Commingling personal and business funds, failing to observe corporate formalities (no meetings, no resolutions, no records), undercapitalization at formation, using the entity as a personal bank account, fraudulent misrepresentation of the entity's financial condition, and personal guarantees signed by the owner.
How do I prevent veil piercing?
Maintain separate bank accounts for personal and business funds. Observe all corporate formalities — hold required meetings, maintain minutes, and pass required resolutions. Adequately capitalize the business. Don't use the business entity for personal purposes.
Can an LLC be pierced in the same way as a corporation?
Yes, though some states apply different standards to LLCs than corporations. The fundamental principle — that the separate legal existence of the entity will be respected unless it has been abused — applies to both.
Does signing a personal guarantee mean the veil has already been pierced?
No. A personal guarantee is a voluntary assumption of personal liability for a specific obligation — it does not affect the entity's liability protection for other obligations or make the owner personally liable for all entity debts.
Can one LLC owner be held liable for another owner's veil piercing behavior?
Generally, veil piercing reaches the owners who participated in or benefited from the abusive conduct. An innocent passive owner who did not participate in the conduct is less likely to be personally liable.
