Tax Benefits for Each Type of Business Structure: LLC, S-Corp, Sole Proprietorship and More

Updated on January 30, 2025 by Tim Donahue

Which Structure Offers the Best Tax Benefits?

Every business structure offers certain benefits.

Here’s a great run down of the basic tax benefits you can get from each of the main business entities.  Note this is NOT legal advice – always consult with your tax expert! πŸ™‚ 

Tax Benefits of Incorporating

1. General Tax Benefits (Apply to Any Business Structure)

These tax benefits apply to all businesses, regardless of whether they operate as a sole proprietorship, LLC, S-corp, or C-corp.

  • Deductible Business Expenses – Businesses can deduct ordinary and necessary expenses, such as rent, utilities, supplies, advertising, and salaries.
  • Retirement Plan Contributions – Business owners can set up SEP IRAs, Solo 401(k)s, or defined benefit plans, allowing them to defer taxes on higher retirement contributions than regular employees.
  • Healthcare Deductions – Businesses can deduct health insurance premiums for employees and, in some cases, for the owner.
  • Home Office Deduction – If operating from home, a business can deduct a portion of rent, utilities, and internet costs.
  • Vehicle & Mileage Deductions – Businesses can deduct vehicle expenses used for business purposes, either using the IRS mileage rate or actual expenses (fuel, maintenance, insurance).
  • Depreciation of Assets – Businesses can deduct the cost of equipment, vehicles, and property over time using bonus depreciation or Section 179 deductions.
  • Self-Employment Tax Reduction (For Certain Entities) –
    • Sole proprietors and partnerships pay self-employment tax (15.3%) on all net income.
    • By incorporating as an S-corp, owners can pay themselves a salary and take the rest as distributions, reducing payroll taxes.

2. Tax Benefits by Business Structure

These benefits are unique to specific business structures.

A. LLC-Specific Tax Benefits

  • Pass-Through Taxation – LLC profits are not taxed at the corporate level; instead, they pass through to the owner’s personal tax return, avoiding double taxation.
  • Flexible Tax Treatment – LLCs can elect to be taxed as sole proprietorships, partnerships, S-corps, or even C-corps, providing flexibility in tax planning.
  • Qualified Business Income (QBI) Deduction – LLCs qualify for the 20% QBI deduction, reducing taxable income for pass-through entities.

B. S-Corp-Specific Tax Benefits

  • Reduced Self-Employment Taxes – Owners can split income between salary (subject to payroll taxes) and distributions (not subject to self-employment tax), lowering overall tax liability.
  • Pass-Through Taxation – Like an LLC, an S-corp avoids double taxation, with profits flowing to the owner’s personal tax return.
  • Health Insurance Premium Deduction for Owners – An S-corp owner who owns more than 2% of the company can deduct health insurance premiums.

C. C-Corp-Specific Tax Benefits

  • Lower Corporate Tax Rate – The flat corporate tax rate is 21%, often lower than individual tax rates for high earners.
  • Retained Earnings Strategy – Unlike pass-through entities, C-corps can retain earnings inside the business without triggering personal tax liability.
  • More Tax-Deductible Fringe Benefits – C-corporations can fully deduct health insurance, life insurance, travel expenses, education assistance, and other fringe benefits for owners and employees.
  • Potential for Lower Taxes on Dividends – Qualified dividends from a C-corp are taxed at capital gains rates (typically 15% or 20%), which can be lower than ordinary income tax rates.
  • R&D Tax Credits – C-corps investing in research and development can qualify for federal R&D tax credits.
