Pennsylvania Sole Proprietorship vs LLC:
Fees, Taxes, and Decision Guide (2026)
Pennsylvania is one of the cheapest states for LLC maintenance: a single decennial report every ten years for $7. The bigger ongoing cost is the local Earned Income Tax in most municipalities, which applies to both structures.

5-Year Cost Comparison for Pennsylvania Residents
| Structure | Year 1 | Years 2-5 (each) | 5-Year Total (state-level only) |
|---|---|---|---|
| Sole Proprietorship | $70 (Fictitious Name, if used) | $0 | $0-$70 |
| Pennsylvania LLC | $125 | $0.70 / yr avg | $128 |
Decennial report fee $7 amortised to $0.70/yr. State PIT 3.07% and local EIT apply to business profit under both structures and are not included above.
Pennsylvania-Specific Considerations
Pennsylvania's flat 3.07% PIT applies to both structures
PA personal income tax is a flat 3.07% on net business income, applied identically to sole proprietors (Schedule C income) and LLC members (pass-through). No bracket advantage either way.
Decennial report, not annual
Most states require an annual or biennial report. PA requires only a Decennial Report once every 10 years (years ending in 1: 2021, 2031, etc.) for $7. This makes PA one of the cheapest states for ongoing LLC maintenance, second only to no-report states like Ohio and Arizona.
Local Earned Income Tax in most municipalities
Most PA municipalities and school districts levy a local Earned Income Tax of 1.0% to 3.9% on net business income, paid quarterly via the local tax collector (typically Berkheimer or Keystone Collections Group). This applies to sole proprietors and LLC members equally. Philadelphia is the exception: it runs the Business Income and Receipts Tax (BIRT) and Net Profits Tax (NPT) instead, which apply to both structures.
Sole prop DBA in Pennsylvania
Sole proprietors using a business name other than their legal name must register a Fictitious Name with the Department of State for $70. The registration is one-time (no annual renewal). LLCs use the registered LLC name and do not need separate DBA registration unless operating under a different name.
Specific Recommendations for Pennsylvania Residents
Stay sole prop if...
- Revenue under $30k and low-risk work
- You do not need the LLC for client or grant reasons
- You are comfortable handling local EIT directly
Form a Pennsylvania LLC if...
- Revenue above $50k and considering S-Corp election later
- Physical services, contracting, or liability-heavy work
- Pennsylvania's $125 filing is the lowest-friction in the region
