Protect Your Business & Personal Assets
Business Banking for Personal Asset Protection
Using dedicated business banking and credit accounts is essential for personal asset protection.
When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued. In business law, this is referred to as piercing your corporate veil.
You can protect your business with these two steps:
1. Opening a business bank account:
- Separates your personal assets from your company's assets, which is necessary for personal asset protection.
- Makes accounting and tax filing easier.
2. Getting a business credit card:
- Helps you separate personal and business expenses.
- Builds your company's credit history, which can be useful to raise capital later on.
Business insurance helps you manage risks and focus on growing your business. The most common types of business insurance are:
- General Liability Insurance: A broad insurance policy that protects your business from lawsuits. Most small businesses get general liability insurance.
- Professional Liability Insurance: A business insurance for professional service providers (consultants, accountants, etc.) that covers against claims of malpractice and other business errors.
- Workers' Compensation Insurance: A type of insurance that provides coverage for employees’ job-related illnesses, injuries, or deaths.In South Dakota, businesses with one or more employees, including LLC members and corporate officers, are required by law to have workers compensation insurance.

Properly Sign Legal Documents
Improperly signing a document as yourself and not as a representative of the business can leave you open to personal liability. When signing legal documents on behalf of your company, you could follow this formula to avoid problems:
- Formal name of your business
- Your signature
- Your name
- Your position in the business as its authorized representative
See the image below for an example.
This ensures that you are signing on behalf of your LLC and not as yourself.
Keep Your Company Compliant
To operate your LLC you must comply with federal, state, and local government regulations. For example, restaurants likely need health permits, building permits, signage permits, etc.
The details of business licenses and permits vary from state to state. Make sure you read carefully. Don't be surprised if there are short classes required as well.
Fees for business licenses and permits will vary depending on what sort of license you are seeking to obtain.

Avoid Automatic Dissolution
LLCs may face fines and even automatic dissolution when they miss one or more state filings. When this happens, LLC owners risk the loss of limited liability protection. A quality registered agent service can help prevent this outcome by notifying you of upcoming filing deadlines and by submitting reports on your behalf.
