LLC vs Sole Proprietor Calculator
Estimate the first-year and ongoing cost of forming an LLC, then see how that cost compares with a few practical readiness factors. This is a planning tool, not a recommendation.
This tool estimates LLC costs and helps organize business-readiness factors. It does not determine whether you should form an LLC or whether an LLC is legally required.
State costs vary widely. Check your state's official business-filing website before relying on these numbers.
LLC Cost & Readiness Statement
Updates automatically as you type.
Modeled federal self-employment-tax change: $0. For an individual owner, a default single-member LLC is generally treated like a sole proprietorship for federal income-tax purposes, and its business earnings are generally subject to self-employment tax in the same manner. Forming the LLC alone does not create federal self-employment-tax savings. Tax elections and other entity classifications are outside this simple calculator.

Answer the questions above to see which factors apply to your situation.
Sole proprietorship is likely sufficient for now. Revisit this if your risk, client requirements, or income consistency change.
What This Calculator Can and Cannot Tell You
This tool can estimate the cash cost of forming and maintaining an LLC, and organize a few common readiness factors — risk, client requirements, financial separation, income consistency, and administrative readiness — into a single planning signal.
It cannot tell you whether an LLC is legally required for your business, whether it will hold up in a specific liability situation, or how it interacts with your state's laws, your contracts, your insurance, or your specific tax situation. Those questions depend on facts this calculator does not have.
Sole Proprietor
The default if you do nothing.
- No separate formation step or state filing — you're automatically a sole proprietor once you start doing business for profit.
- Business and personal assets are not legally separated.
- Business income and expenses are typically reported on your personal tax return.
- No ongoing state filing fees in most states, though local licenses may still apply.
Single-Member LLC
A formal entity you choose to create.
- Requires a state filing, a formation fee, and often an annual report or maintenance fee.
- May offer separation between business and personal liabilities, subject to state law and how the business is run.
- By default, taxed like a sole proprietorship for federal income tax — the LLC itself doesn't change your federal income tax return.
- Comes with more administrative responsibility: separate bank accounts, recordkeeping, and state compliance.
Does an LLC Reduce Self-Employment Tax?
Modeled federal self-employment-tax change: $0. For an individual owner, a default single-member LLC is generally treated like a sole proprietorship for federal income-tax purposes, and its business earnings are generally subject to self-employment tax in the same manner. Forming the LLC alone does not create federal self-employment-tax savings. Tax elections and other entity classifications are outside this simple calculator.
When Staying a Sole Proprietor May Be Enough
- Income is experimental or still early — you're testing whether the business is viable.
- Clients or platforms have no entity requirement.
- Business-related risk is low, and formation/maintenance costs would be a large share of current profit.
- You're not yet ready to keep up with separate accounts, recordkeeping, and state compliance.
When Forming an LLC May Be Worth Considering
- Income has become consistent or is clearly growing.
- A client or platform prefers or requires a registered business entity.
- Business-related risk is medium or high.
- You want a clearer line between business and personal finances.
- You're administratively ready to maintain a separate entity.
None of these factors alone make forming an LLC necessary — they're signals worth discussing with a professional, not a checklist to complete.
