| Factor | LLC | Sole Proprietorship |
|---|---|---|
| Personal liability protection | Full protection - personal assets shielded from business debts and lawsuits | No protection - you're personally liable for all business obligations |
| Formation cost & paperwork | Requires Articles of Organization filing and ongoing compliance | Minimal paperwork - can start operating immediately with DBA if needed |
| Taxation | Pass-through taxation by default, but can elect S-Corp or C-Corp status | Pass-through taxation only - business income reported on personal tax return |
| Self-employment tax | Subject to SE tax by default, but S-Corp election can reduce it significantly | All business income subject to self-employment tax (15.3%) |
| Business credibility | Professional image with formal business structure enhances credibility | Less formal appearance may limit credibility with clients and vendors |
| Banking & contracts | Easier to open business accounts and enter contracts in company name | Banking and contracts often done in personal name, creating confusion |
| State fees in Montana | $35 filing fee plus annual report fees | No state filing fees required (DBA filing optional at county level) |
| Conversion path to LLC | Already an LLC - no conversion needed | Can easily convert by filing Articles of Organization with Montana SOS |
When an LLC Makes More Sense
- Your business faces potential liability risks from customers, employees, or professional services
- You want to build business credit separate from your personal credit profile
- You plan to have business partners or investors join your venture
- Your annual profit exceeds $60,000 and you want to reduce self-employment taxes through S-Corp election
When a Sole Proprietorship Makes More Sense
- You're testing a low-risk business idea with minimal startup costs
- Your business has very low liability exposure and minimal regulatory requirements
- You want the simplest possible business structure with no ongoing compliance
- Your annual profit is under $30,000 and the LLC filing fee represents a significant cost
Tax Deep Dive
Sole Prop Tax
Sole proprietorships use pass-through taxation where all business income flows to your personal tax return on Schedule C. You'll pay self-employment tax at 15.3% on all net business income, covering Social Security and Medicare contributions.
Llc Default Tax
By default, single-member LLCs are taxed identically to sole proprietorships with pass-through taxation and full self-employment tax liability. However, LLCs have the flexibility to elect different tax treatments as your business grows.
Llc S Corp Election
Montana LLCs can elect S-Corporation tax status to potentially reduce self-employment taxes by paying reasonable salary subject to SE tax while taking additional profits as distributions. This strategy typically becomes beneficial when annual profits exceed $60,000-$80,000 in Montana.
