    The legal structure of your business is a tax planning decision that can save or cost you thousands of dollars per year.

    Sole Proprietorship / Single-Member LLC

    The simplest structure. All business income flows to your personal tax return. You pay self-employment tax on all net business income: 15.3% on the first $184,500 in 2026 and 2.9% above that. Filing is straightforward: Schedule C on your personal return.

    S-Corporation

    An S-Corp is a tax election, not an entity type. The key benefit: you split business income into a reasonable salary (subject to FICA/payroll taxes) and distributions (not subject to self-employment tax).

    The bottom line

    The S-Corp typically becomes beneficial when net business income exceeds $60,000-$80,000.

    C-Corporation

    C-Corps pay corporate tax (21% federal) on profits. Distributions to shareholders are taxed again as dividends - double taxation. However, C-Corps offer unique advantages for specific situations: certain fringe benefits are deductible by the corporation and not taxable to the employee-owner.

    The Decision Framework

    • Below $60,000 net income: Sole proprietorship/LLC is usually sufficient
    • $60,000-$200,000: S-Corp election often makes sense
    • Above $200,000: analysis becomes more complex - consider a tax professional

    Forming the Entity

    Whichever structure you land on, forming an LLC or corporation means filing formation paperwork with your state and, in most states, naming a registered agent: the party that receives legal and state mail on the business's behalf. An S-Corp is a tax election you make after the entity exists, so it starts with the same formation step.

    Northwest Registered Agent is one option that handles both business formation and registered agent service. It is the service we use for Mudofa. Comparing a few providers on price and what is included is always worth doing.

    What would you do?

    Alex's consulting business nets $150,000. She's currently a sole proprietor paying self-employment tax on the full amount.

    Your Move

    Calculate your current self-employment tax (net income × 15.3%, approximately). Then estimate what a 'reasonable salary' would be for your role. The difference between your net income and that salary is your potential SE tax savings from S-Corp election.
