Choose the structure before filing the paperwork

An LLC, corporation or partnership arrangement should reflect the business you are building. We help you evaluate who will own it, who will manage it, how it will be funded and what should happen when ownership changes.

Tax treatment is a related but separate decision. An LLC is a state-law entity. S-corporation status is a federal tax election available to qualifying entities, including eligible LLCs. The right choice depends on your circumstances and should be coordinated with your tax adviser. IRS guidance on LLC classification.

What formation planning can include

The engagement is tailored to the business. Depending on your needs, work may include:

• Comparing entity structures and management arrangements.
• Preparing and filing formation documents.
• Drafting an operating agreement, bylaws or ownership agreement.
• Documenting initial contributions, ownership and authority.
• Addressing owner departures, transfers and buyouts.
• Assisting with an EIN and appropriate tax-election steps.
• Reviewing registration needs when operating across state lines.
• Identifying recordkeeping, contract and compliance priorities.

The scope and fees are agreed before work begins. Filing an entity does not by itself answer every licensing, tax, employment or operational question.

Put the owners’ agreement in writing

Two owners can agree on a company name and still disagree about almost everything that matters later. Who can borrow money? Must both owners approve a major contract? What happens if one stops working or wants to sell?

An operating agreement should address those decisions while the owners can discuss them constructively. Missouri law expressly provides for an operating agreement covering the LLC’s affairs and owners’ rights. See RSMo 347.081.

Our corporate governance services support the records and agreements your business needs as it develops.

Privacy and compliance deserve a separate review

We can discuss lawful ways to limit unnecessary exposure of personal information. Public filing requirements differ by jurisdiction and document, and no structure promises secrecy from banks, tax authorities or lawful legal process.

Current FinCEN guidance exempts U.S.-created companies from federal BOI reporting. Entities formed under foreign-country law require a separate analysis. State registrations and other obligations still need attention. FinCEN’s current BOI guidance.

From startup to ongoing counsel

Formation is the beginning of the relationship your company has with its owners, customers and vendors. As the business grows, ongoing advisory services can support contracts, ownership changes and other legal decisions.

Common questions

Do I need an LLC or an S-corporation?

First decide the legal entity. Then evaluate its tax treatment. An eligible LLC may elect S-corporation taxation; that does not make the operating agreement or other legal planning unnecessary.

Can you help if I already filed the LLC?

Yes. We can review your existing structure, ownership records and operating agreement, then discuss any gaps and the scope of appropriate follow-up work.

Can we handle formation planning virtually?

Yes. We provide virtual services throughout Illinois and Missouri. Tell us where the business will operate and who will own it so we can identify relevant state requirements.

Talk through your business before committing to a structure
