Forming an LLC gives you a legal shield between your personal assets and your business liabilities. A creditor who sues your company — and wins — can take the company's money. But they cannot touch your personal savings, your home, or your car. That's the promise.
Courts don't honor that promise automatically. They only protect the separation if you actually maintain it. Research shows that roughly 50% of corporate veil piercing cases succeed — meaning courts found the owner hadn't treated the business as a genuinely separate entity. Solo founders are the highest-risk group.
What the corporate veil actually is
When you incorporate or form an LLC, the law creates a legal fiction: your business is a separate "person" with its own rights and obligations. This is the corporate veil. Courts respect it as long as you do — running the business with proper separation between personal and business affairs.
"Piercing the veil" is what happens when a court decides the separation was an illusion — that the business and the owner are effectively the same entity. At that point, the owner becomes personally liable for the business's debts and judgments.
Why solo founders are at higher risk
Single-member LLCs and closely-held corporations are scrutinized far more heavily than multi-member entities. When one person controls everything — makes decisions, writes checks, signs contracts — the line between company and individual gets blurry fast. Courts know this and look harder.
There's also no one else watching. In a multi-person company, other members notice when someone pays for personal groceries out of the company account. When you're the only person, these habits can develop invisibly.
Five mistakes that pierce the veil
1. Commingling funds
This is the most common — and the most damaging. Commingling means mixing personal and business finances: paying personal expenses from the business account, depositing client checks into your personal account, or using one card for both personal and business purchases without documentation.
One personal charge on the business card won't sink your veil — but the habit will. Courts look at patterns, not individual transactions. A year of commingled charges across statements tells a clear story, and it's not one you want told in litigation.
2. No corporate formalities
Corporations must hold annual meetings, keep minutes, and document major decisions. LLCs have lighter requirements — but "lighter" doesn't mean "none." A single-member LLC should maintain a written Operating Agreement and document significant decisions: taking out a loan, entering a major contract, changing the business's direction.
You don't need to hold meetings with yourself. A one-paragraph written resolution dated and signed by you covers it. The goal is a paper trail that shows the business made decisions, not just the individual.
3. Undercapitalization
Forming an LLC with $0 in it, then immediately running all expenses through the entity, signals that the business exists only to shelter personal assets — not to operate legitimately. Courts call this undercapitalization, and it's a factor in piercing analysis.
The fix isn't depositing a large sum. It's ensuring the company has enough capital to meet its reasonably foreseeable obligations. For a solo service business, this might mean keeping at least two months of operating expenses in the account.
4. Using the business as a personal piggy bank
This goes beyond commingling. It's systematically running personal lifestyle expenses — vacations, personal clothing, household furniture — through the company and claiming them as business expenses. Distinct from commingling because it involves active misclassification, not just sloppy accounting.
The correct approach: pay yourself a salary or take documented distributions. If you need more money for personal expenses, take a distribution. Don't route personal expenses through the company and call them business costs.
5. Tax non-compliance
Missing payroll tax deposits, unfiled annual returns, or unpaid state franchise taxes all signal neglect of the entity. Courts interpret consistent non-compliance as evidence that the owner doesn't genuinely treat the business as a separate entity — which is exactly the argument for piercing.
The practical habits that protect you
- One business bank account, used exclusively for business. Personal expenses never come out of it.
- One business credit card (or debit card), used exclusively for business expenses.
- If you accidentally pay a business expense from personal funds: document it as a capital contribution or loan to the company. Write a one-sentence note to yourself dated that day.
- Take money out correctly: distributions documented as distributions, salary paid through payroll, not ad-hoc transfers labeled "owner draw" with no documentation.
- Keep a simple corporate records folder (Google Drive works). Save your Operating Agreement, EIN letter, major contracts, and any written resolutions.
- File state annual reports on time and pay franchise taxes. Set a calendar reminder.
What this looks like in practice
The standard for solo founders isn't perfection — it's demonstrable consistency. A court evaluating veil-piercing looks for a pattern of ignoring the entity, not a single mistake. One transaction paid from the wrong account doesn't pierce anything. A year of treating the business account as a personal wallet does.
The practical test: could someone looking at your bank statements from last year tell unambiguously which transactions were business and which were personal? If the answer is no, you have commingling to clean up.
The reimbursement solution
Instead of paying personal benefit expenses from the company account, pay them from your personal card and reimburse yourself properly through a documented Accountable Plan (covered in Post 6). This creates a clear audit trail: personal card → personal payment → company reimburses with documentation. No commingling, no veil risk.
Frequently asked questions
- What is the corporate veil and why does it matter?
- The corporate veil is the legal separation between you personally and your LLC or corporation. It means creditors and lawsuits generally cannot reach your personal assets. If you mix personal and business finances, fail to keep records, or do not follow basic formalities, a court can "pierce the veil" and hold you personally liable.
- What voids the corporate veil for a solo founder?
- The most common ways solo founders accidentally void their corporate veil: paying personal expenses from the business account, not maintaining a separate business bank account, failing to sign contracts in the company name, not keeping any meeting minutes or written resolutions, and undercapitalizing the business from the start.
- Does a single-member LLC have a corporate veil?
- Yes, but courts scrutinize single-member LLCs more closely than multi-member LLCs. The same liability protection exists, but you must be more diligent about maintaining separation — separate bank accounts, separate credit cards, and proper documentation of all business decisions.
