Many small business owners in the United States choose to start as sole proprietors for simplicity. But as their business grows, they may form a Limited Liability Company (LLC) for liability protection or credibility. This raises an important question: Can you still be a sole proprietor if you have an LLC? Let’s explore what this means from a tax treatment and business classification standpoint, especially as it relates to IRS rules in 2025.

🧾 Sole Proprietor vs. LLC: Key Definitions
- Sole Proprietor: An individual running an unincorporated business, taxed using Schedule C with Form 1040.
- LLC: A legal entity formed at the state level, providing limited liability protection. Can be owned by one (single-member) or multiple people (multi-member).
📌 IRS Default Treatment: LLC = Sole Proprietor (If Single-Member)
If you form a single-member LLC and don’t elect any other tax classification (like S corp), the IRS considers your LLC as a “disregarded entity.” This means:
- You’ll file taxes just like a sole proprietor.
- Use Schedule C to report income and expenses.
- Pay self-employment tax using Schedule SE.
- Make estimated tax payments using Form 1040-ES.
✅ When Does an LLC Stop Being Treated as a Sole Proprietor?
Your LLC will no longer be treated as a sole proprietorship for tax purposes if:
- You file Form 8832 to elect C Corporation status.
- You file Form 2553 to elect S Corporation status.
- Your LLC has more than one member, making it a partnership by default.

💡 Tax Advantages of Keeping Your LLC as a Sole Proprietor
- No separate business tax return required
- Simplified filing through Form 1040 + Schedule C
- Still offers liability protection under state law
- No corporate formalities required (like board meetings)
📂 Forms You’ll Need in 2025
As a single-member LLC taxed as a sole proprietor, you’ll typically need the following forms:
- Form 1040 – Individual Income Tax Return
- Schedule C – Profit or Loss from Business
- Schedule SE – Self-Employment Tax
- Form 1040-ES – Estimated Tax Payments
- Form 4562 – Depreciation (if claiming capital expenses)
- Form 8829 – Home Office Deduction (if applicable)
⚠️ Common Mistake: Thinking LLC Means Separate Taxes
Many new business owners mistakenly believe that forming an LLC changes their tax status automatically. That is not the case unless you formally elect a new tax treatment with the IRS.

📌 Final Thoughts
Yes, you can still be a sole proprietor from a tax perspective even after forming a single-member LLC. The IRS will treat your LLC as a disregarded entity unless you opt out of default taxation. This allows you to continue using Schedule C, Schedule SE, and Form 1040 while enjoying limited liability protection at the state level.
As always, consult with a tax advisor to determine whether electing S Corp status or remaining a disregarded entity is best for your business’s financial goals.
