Complete Guide to Pennsylvania LLC Taxes in 2025
Pennsylvania offers one of the lowest flat income tax rates in the nation at 3.07%, combined with what is effectively the cheapest annual filing requirement in the US ($7 decennial report). However, the Keystone State's unique local tax system -- where municipalities impose their own earned income taxes of 1-3.07% -- can significantly increase the total tax burden. This guide covers all aspects of PA LLC taxation.
How Pennsylvania Taxes LLCs
Pennsylvania treats LLCs as pass-through entities. The LLC does not pay PA income tax at the entity level. Profits pass through to members who report on PA Form PA-40. Multi-member LLCs file Form PA-20S/65.
A critical difference: Pennsylvania does not allow the same deductions as the federal system. PA uses eight specific classes of income and has its own deduction rules. Many common federal deductions (like the standard deduction and QBI deduction) do not apply at the PA level.
Key Point: While PA's 3.07% flat rate looks low, the lack of a standard deduction and the addition of local earned income taxes (1-3.07% in most areas, 3.75% in Philadelphia) mean the effective total state+local rate is often 4-6%+.
Pennsylvania Income Tax
| Tax Component | Rate | Notes |
|---|---|---|
| PA State Income Tax | 3.07% flat | On all taxable income |
| Local EIT (most areas) | 1-3.07% | Varies by municipality |
| Philadelphia Wage Tax | 3.75% (residents) | In addition to state tax |
| State Sales Tax | 6% | Plus 1-2% local in Philly/Allegheny |
| Decennial Report | $7 | Every 10 years |
Pennsylvania's Unique Local Tax System
PA is one of the few states where local income taxes are nearly universal. Almost every municipality imposes an Earned Income Tax (EIT) on residents. For LLC members, this means paying both state (3.07%) and local (typically 1-3.07%) income tax on business earnings.
Federal Taxes for PA LLC Owners
- Self-Employment Tax (15.3%): Standard federal rates
- Federal Income Tax: 10% to 37% for 2025
- QBI Deduction: Up to 20% federally (not applicable at PA state level)
Tax Tip: PA's flat 3.07% rate means the biggest savings opportunities are at the federal level. S-Corp election can save thousands on SE tax. Use our S-Corp Tax Calculator to compare.
PA LLC Filing Deadlines
| Filing Type | Deadline | Extension |
|---|---|---|
| Individual (PA-40) | April 15 | October 15 |
| Partnership (PA-20S/65) | March 15 | September 15 |
| Local EIT Return | April 15 | Varies by municipality |
| Estimated Payments | Apr 15, Jun 15, Sep 15, Jan 15 | None |
PA LLC Formation Costs

PA vs. Neighboring States
| State | Income Tax | Annual Fee | Entity Tax |

| New Jersey | 1.4-10.75% | $75 | None |
| Ohio | 0-3.5% | $0 | CAT 0.26% |

Common PA LLC Tax Mistakes
- Forgetting local EIT: Nearly all PA municipalities levy local income tax -- don't ignore it
- Assuming federal deductions apply: PA has its own deduction rules; the standard deduction and QBI don't apply at the state level
- Philadelphia tax complexity: Philly has Business Income and Receipts Tax (BIRT) plus Net Profits Tax in addition to the wage tax
- Missing estimated payments: Both state and local require estimated payments
PA Conformity Note: Pennsylvania does NOT conform to federal AGI. It uses eight classes of income with specific rules for each. Consult PA-40 instructions carefully -- many federal deductions don't carry over to Pennsylvania.
Pennsylvania's Unique Tax Structure Explained
Pennsylvania's tax system for LLC owners is fundamentally different from most states in several important ways. While the 3.07% flat rate appears attractively low, understanding the nuances of PA's tax code is essential for accurate planning. The most critical distinction is that Pennsylvania does not use federal adjusted gross income (AGI) as its starting point.
Instead, PA uses eight specific classes of income, each with its own rules for what constitutes taxable income. The eight classes are: compensation, net profits from business, interest, dividends, gains from disposition of property, rents and royalties, gambling income, and income from estates and trusts. For LLC owners, the "net profits" class is most relevant.
Crucially, Pennsylvania does not allow the federal standard deduction, the QBI deduction (Section 199A), or many other federal deductions. This means your PA taxable income can be significantly higher than your federal taxable income, partially offsetting the benefit of the low 3.07% rate.
Pennsylvania Local Earned Income Tax (EIT) System
The local EIT is the most significant additional tax burden for PA LLC owners. Nearly every municipality in Pennsylvania imposes an earned income tax, and for self-employed individuals including LLC owners, this applies to net business profits. The rates typically range from 1% in smaller municipalities to 3.07% in some areas.
The total EIT rate for a given location is typically split between the municipality and the school district. For example, a municipality might levy 1% and the school district 0.5% for a combined 1.5% local rate. In Philadelphia, the situation is different -- the city imposes its own wage tax at 3.75% for residents (3.44% for non-residents who work in the city).
Key facts about PA local EIT for LLC owners:
- Applies to net profits: Your LLC's net profit is subject to local EIT in addition to the 3.07% state tax
- Based on work location and residence: You may owe EIT to both the municipality where you work and where you live, though credits typically prevent double taxation
- Quarterly estimated payments: Local EIT also requires quarterly estimated payments, separate from state and federal
- Filed through local collectors: PA uses a system of local tax collectors (Berkheimer, Keystone Collections, etc.) rather than filing with the state
Philadelphia Business Taxes for LLCs
Philadelphia deserves special attention because it imposes additional business taxes beyond the state tax and standard local EIT. If your LLC operates in Philadelphia, you may be subject to:
- Business Income and Receipts Tax (BIRT): A two-part tax consisting of a net income component (6.20% in 2025, declining annually) and a gross receipts component (1.415 mills per dollar of gross receipts, also declining). The BIRT has an exemption for the first $100,000 of gross receipts.
- Net Profits Tax (NPT): 3.75% on net profits for Philadelphia residents (3.44% for non-residents). This is in addition to the BIRT.
- Wage Tax: For employees of the LLC, Philadelphia imposes a 3.75% wage tax (residents) or 3.44% (non-residents).
The combined Philadelphia tax burden for an LLC can be staggering. A Philadelphia resident operating an LLC could face: 3.07% PA state tax + 3.75% NPT + 6.20% BIRT (net income) + 1.415 mill gross receipts tax, plus federal taxes. The effective combined state and local rate can exceed 13% before federal taxes are considered.
PA LLC Formation and Compliance Details
Pennsylvania's LLC compliance requirements are relatively light compared to many states:
- Certificate of Organization: File with the PA Department of State ($125 fee). Can be filed online.
- No registered agent required: PA is one of the few states that does not require an LLC to maintain a registered agent. Instead, the LLC must provide a registered office address in PA.
- Decennial Report: A report filed every 10 years ($7 fee) -- essentially the cheapest ongoing compliance requirement in the nation.
- No annual report: No annual or biennial filing is required between decennial reports.
- EIN: Obtain from the IRS for free.
The lack of an annual report and the minimal $7 decennial fee make PA one of the cheapest states for ongoing LLC maintenance. However, the local EIT filing requirements add significant compliance complexity that offsets this simplicity.
Tax Planning Strategies for PA LLC Owners
Effective tax planning for Pennsylvania LLC owners focuses on several key areas:
- Maximize business deductions: Since PA does not allow the standard deduction, every legitimate business deduction directly reduces your 3.07% state liability and local EIT.
- S-Corp election evaluation: S-Corp distributions may not be subject to local EIT in some municipalities, providing an additional layer of savings beyond the federal SE tax benefit.
- Retirement contributions: PA allows deductions for retirement plan contributions, reducing both state and local tax liability.
- Location optimization: Since local EIT rates vary significantly, the municipality where your LLC operates and where you live can meaningfully impact your total tax burden. Moving from a 3% local EIT municipality to a 1% one saves 2% on all business income.
- Philadelphia exit planning: For LLC owners in Philadelphia, the combined BIRT + NPT + state tax creates one of the highest local business tax burdens in the nation. Relocating outside Philadelphia while maintaining clients can produce significant savings.
PA vs. Delaware LLC Formation
Many business owners consider Delaware as an alternative to Pennsylvania LLC formation due to Delaware's business-friendly reputation. However, for LLC owners who actually live and work in Pennsylvania, forming in Delaware provides no tax benefit -- you still owe PA taxes on income earned in PA, plus you pay Delaware's $300 annual franchise tax. Form your LLC in Pennsylvania if that is where you operate; Delaware formation only makes sense for specific legal structure or investor requirements.
