Key differences from most states

Key differences from most states table

Feature	Pennsylvania rule
Standard deduction	None
Personal exemption	None
Itemized deductions	Not allowed (PA does not use federal Schedule A)
Starting point	NOT federal AGI or federal taxable income — PA computes each class of income independently
Net operating loss	Not allowed (losses in one class cannot offset income in another class)
Retirement income	Fully exempt (pensions, 401(k), IRA distributions, Social Security)

Eight classes of income

Pennsylvania taxes eight separate classes of income. Each class is computed independently, and losses in one class generally cannot offset income in another.

Eight classes of income table

Class	Description	Relevant to sole proprietors?
1. Compensation	Wages, salaries, tips, fees	Yes (if also W-2 employed)
2. Net profits	Business income (Schedule C equivalent)	Yes — primary class
3. Interest	Interest income	Yes
4. Dividends	Dividend income	Yes
5. Rental/royalty	Net income from rents and royalties	Yes (if applicable)
6. Estate/trust	Income from estates and trusts	Rare

Eligibility income	Single (no dependents)	With 1 dependent	With 2+ dependents
100% forgiveness	$6,500 or less	$6,500 plus $9,500 per dep	Varies

• Threshold increase per dependent — The threshold increases are $9,500 per dependent for 2025. The program phases out gradually. See Schedule SP. (Schedule SP)

Section 3: How this skill works with the federal return

Pennsylvania does NOT start from federal AGI or federal taxable income. Instead, Pennsylvania computes each class of income independently using Pennsylvania-specific rules.

For a sole proprietor, the most important class is Class 2: Net Profits, which corresponds (roughly) to federal Schedule C but with significant differences:

Key flow for self-employed:

1. Compute PA net profits (PA Schedule C equivalent with PA-specific rules)
2. Compute each other class of income separately
3. Sum all eight classes → Total PA taxable income
4. Multiply by 3.07% → PA income tax before credits
5. Apply tax forgiveness (if eligible) and other credits → PA income tax liability

Critical differences in computing net profits

Federal deduction vs PA treatment table

Federal deduction	PA treatment
50% of self-employment tax	Not deductible on PA return
Self-employed health insurance	Not deductible on PA return (but may be deductible as a business expense if structured correctly)
SEP/SIMPLE/solo 401(k) contributions	Not deductible on PA return (PA exempts the retirement income when distributed, but does not allow the contribution deduction)
Home office deduction	Allowed (if calculated per PA rules — generally follows federal)
Business expenses (Schedule C)	Generally allowed (ordinary and necessary business expenses are deductible)
Depreciation	PA uses its own depreciation rules — no bonus depreciation; PA follows federal MACRS but without §168(k) bonus
§179 expensing	PA conforms to $25,000 limit (not the federal $1,220,000+ limit). Excess must be depreciated under MACRS.
Net operating loss	Not allowed for individuals. Business losses cannot offset income from other classes, and PA does not allow NOL carryforward for individuals.

Section 4: Self-employed specific rules

Net profits computation (Class 2)

• Net profits computation basis — The PA net profits computation is on PA Schedule C (different from federal Schedule C). The starting point is gross receipts minus cost of goods sold, minus allowable business expenses under PA rules.
• §179 limited to $25,000 — If the taxpayer claimed more than $25,000 in §179 on the federal return, the excess must be depreciated over the asset's life on the PA return.
• No bonus depreciation — PA does not conform to §168(k). Any bonus depreciation claimed federally must be added back, and regular MACRS depreciation substituted. (§168(k))
• No NOL — If net profits are negative, the loss stays within Class 2. It cannot reduce compensation (Class 1) or other income classes. PA does not allow individual NOL carryforward.

Loss limitation (critical)

• No offset between classes — Pennsylvania does not allow losses in one class of income to offset income in another class. If a sole proprietor has a $20,000 loss in net profits (Class 2) and $80,000 in compensation (Class 1), the taxpayer pays 3.07% on $80,000. The $20,000 loss is wasted — it cannot be carried forward.

This is one of the most taxpayer-unfriendly provisions in the state tax landscape and catches many preparers off guard.

Local earned income tax (warning)

• Local EIT filing requirement — Pennsylvania's over 2,500 municipalities and school districts impose local earned income taxes (EIT), typically 1%–3.9% combined. Self-employed individuals must file local EIT returns in their resident jurisdiction. The largest local taxes are: - Philadelphia: 3.75% wage tax (residents) / 3.44% net profits tax (verify 2025) - Chester City: 3.75% - Reading: 3.6% Local EIT is NOT covered by this skill but represents a significant additional tax burden.

Reciprocal agreements

• Reciprocal agreement states — Pennsylvania has reciprocal agreements with IN, MD, NJ, OH, VA, and WV. If the taxpayer works in one of these states, only Pennsylvania taxes the compensation.

Section 5: Tier 1 rules — deterministic

• R-PA-1. Flat rate of 3.07% — All taxable income from all eight classes is taxed at 3.07%. No brackets, no graduated rates. (R-PA-1)
• R-PA-2. No standard deduction and no personal exemptions — PA does not provide any standard deduction or personal exemption. All income is taxed from dollar one (subject to tax forgiveness for low-income filers). (R-PA-2)
• R-PA-3. §179 limited to $25,000 — If federal §179 exceeds $25,000, add back the excess on the PA return and depreciate over the asset's useful life. (R-PA-3)
• R-PA-4. No bonus depreciation — Add back all §168(k) bonus depreciation claimed on the federal return. Substitute regular MACRS depreciation on the PA return. (R-PA-4)
• R-PA-5. No loss offsets between classes — Business losses (Class 2) cannot offset compensation (Class 1) or any other class. (R-PA-5)
• R-PA-6. Retirement income is fully exempt — Pensions, 401(k) distributions, IRA distributions, and Social Security are all exempt from PA income tax when received. However, the contributions are NOT deductible when made (no above-the-line deduction for SEP/SIMPLE/solo 401(k) on PA return). (R-PA-6)
• R-PA-7. Tax forgiveness for low-income filers — Apply Schedule SP to determine if the taxpayer qualifies for partial or full forgiveness of PA income tax. (R-PA-7)

Section 6: Tier 2 rules — requires judgment

• J-PA-1. Business expense classification — Because PA computes net profits using its own rules, judgment is needed to determine which federal Schedule C expenses are allowable under PA law. Most ordinary and necessary business expenses are allowed, but some items differ. (J-PA-1)
• J-PA-2. Self-employed health insurance deductibility — The federal above-the-line deduction for self-employed health insurance is NOT allowed on the PA return. However, if health insurance premiums are a legitimate business expense of the sole proprietorship (e.g., paid by the business), they may be deductible on PA Schedule C. The distinction requires judgment. (J-PA-2)
• J-PA-3. Depreciation reconciliation — When federal and PA depreciation differ (due to §179 and §168(k) differences), a depreciation schedule tracking PA basis vs. federal basis is required for all depreciable assets. (J-PA-3)
• J-PA-4. Residency determination — PA considers a person domiciled in PA as a resident. The statutory residency test (183+ days in PA) also applies. For taxpayers who moved, part-year resident rules apply. (J-PA-4)

Section 7: Supplier pattern library

Supplier pattern library table

Pattern	Description
Heavy equipment purchaser	Large §179 claim federally. PA limits §179 to $25,000 — must add back excess and compute PA MACRS. Creates ongoing PA/federal depreciation tracking requirement.
Schedule C loss with W-2 income	PA does not allow Class 2 loss to offset Class 1 compensation. Taxpayer pays 3.07% on full W-2 income despite business loss.
SEP contributor	SEP contribution is not deductible on PA return. PA tax on the contribution amount now, but exempt when distributed in retirement.
Low-income freelancer	Check Schedule SP for tax forgiveness. Full forgiveness available if eligibility income is below threshold.
Philadelphia resident	Additional 3.75% city wage tax on all earned income (compensation + net profits). Massive additional burden.

Section 9: Refusal catalogue

• REFUSE-PA-1 — REFUSE to prepare a PA return for a part-year resident or nonresident without determining the apportionment of each class of income to PA-source income. (REFUSE-PA-1)
• REFUSE-PA-2 — REFUSE to allow losses in one class of income to offset income in another class. This is a hard rule — no exceptions. (REFUSE-PA-2)
• REFUSE-PA-3 — REFUSE to apply federal §179 amounts above $25,000 on the PA return. The excess must be depreciated. (REFUSE-PA-3)
• REFUSE-PA-4 — REFUSE to apply federal bonus depreciation on the PA return. PA does not conform to §168(k). (REFUSE-PA-4)
• REFUSE-PA-5 — REFUSE to compute local earned income tax (EIT), Philadelphia wage/net profits tax, or school district taxes. These are separate filings with separate rules. (REFUSE-PA-5)
• REFUSE-PA-6 — REFUSE to deduct SEP, SIMPLE, or solo 401(k) contributions on the PA return. PA does not allow these deductions (but exempts the distributions in retirement). (REFUSE-PA-6)
