Is Your Business Still in the Right Entity Structure? Rethinking LLC vs. S Corp for Tax Efficiency

Your entity structure affects how your business is taxed, how you take income, and how you plan for growth.

Many business owners form an LLC or elect S Corp status early on — and never look back. But as your business evolves, your entity structure should evolve with it.

If you haven’t reviewed your structure recently, it could be costing you in unnecessary taxes, missed deductions, or payroll complications.

At Baker CFO Advisory, this is one of the first areas we review when clients are scaling — because your entity type isn’t just a formality. It’s a strategic lever.

LLC vs. S Corp: What’s the Real Difference?

Understanding the key tax mechanics behind each structure is essential:

• LLC (default tax treatment): Profits pass through directly to the owner(s) and are subject to both income tax and self-employment tax (typically 15.3%). There's no requirement to run payroll.
• S Corporation: Still a pass-through entity, but the owner must take a “reasonable salary” through payroll, and only salary income is subject to self-employment tax. The remaining profits can be distributed and taxed at lower effective rates.
  
  
  

Key tax benefit:

S Corps may reduce self-employment tax liability by splitting compensation between salary and distributions — but only when structured properly and supported by documentation.

When It’s Time to Reevaluate Your Entity

A structure that made sense when you started might no longer serve your goals. Look for these triggers:

• Your profits have exceeded $75K annually
  That’s often where S Corp election begins to make tax sense — especially if you’re not yet on payroll.
• You’re taking owner draws but not a formal salary
  The IRS closely watches for reasonable compensation. Being out of compliance can raise audit risk.
• You’re expanding your team or services
  Adding employees, partners, or revenue streams might call for a structure that supports payroll and scalability.
• You’re planning for sale, succession, or equity changes
  Your exit strategy should align with the tax structure you have today.

How to Run the Numbers Before You Switch

Before making any changes, it’s critical to model your tax position under both structures. Here’s how we approach it:

Calculate current vs. potential tax liability

• Include both federal income tax and self-employment tax
• Account for payroll tax obligations if switching to S Corp.
  
  

​Factor in payroll and administrative compliance

• Will you need to run payroll for the first time?
• Are you ready to handle filings, withholding, and reasonable salary rules?
• Are you ready to file separate tax returns and pay for them?

Project savings and breakeven points

• The benefit of switching should outweigh the added cost and complexity
• In some cases, staying as an LLC provides flexibility if profits are low or variable

Changing Structures:What to Know

If you determine it’s time to make a change, you’ll need to:

• File IRS Form 2553 (for S Corp election) within the required window
• Establish payroll systems and determine reasonable compensation
• Coordinate with your CPA and bookkeeping team to ensure clean implementation
  
  
  

Timing matters — S Corp elections must be made early in the tax year to take effect. We recommend reviewing this in Q1 or Q2 to allow for strategic planning and compliance so that you’ll be ready for next year’s filing deadlines.

Why This Matters for Growing Businesses

Your business may have outgrown your original tax structure — and every year you wait could mean thousands in unnecessary taxes.

Entity selection isn’t about what’s easiest. It’s about what aligns best with:

• Your income goals
• Your team and operational model

• Your long-term exit strategy

The right structure should support your growth — not limit it.
