Pennsylvania State Tax Deductions

Pennsylvania State Tax Deductions – Pennsylvania’s personal income tax (PIT) is a flat 3.07% rate applied to taxable income. Unlike the federal system, Pennsylvania offers very limited deductions—no standard deduction, no personal exemptions, and no broad itemized deductions like mortgage interest or charitable contributions.

This guide explains exactly what Pennsylvania state tax deductions you can claim for tax year 2025 (returns filed in 2026), how to report them on Form PA-40, and the major updates that can help you lower your tax bill.

What Are Pennsylvania State Tax Deductions?

Pennsylvania state tax deductions reduce your PA taxable income before the 3.07% tax is calculated. They fall into two main categories:

  1. Unreimbursed employee business expenses (subtracted directly from compensation on Line 1b of PA-40).
  2. Other deductions reported on Line 10 of PA-40 using Schedule O (MSA, HSA, 529 plans, ABLE accounts, and the new student loan interest deduction).

These deductions are not the same as federal adjustments to income or itemized deductions. Pennsylvania only allows the specific items listed below.

Unreimbursed Employee Business Expenses (PA Schedule UE)

You can subtract 100% of qualifying unreimbursed employee business expenses from your gross compensation. Pennsylvania rules are more generous than federal rules—no 2%-of-AGI floor applies.

Qualifying expenses must be:

  • Ordinary, necessary, reasonable, and directly related to your job
  • Actually paid by you (not reimbursed)
  • Substantiated with records (keep for at least 4 years)

Common examples include:

  • Union dues
  • Required uniforms or protective clothing
  • Tools and supplies (depreciable if useful life >1 year)
  • Professional licenses and malpractice insurance
  • Business travel (mileage, parking, tolls, lodging, meals while traveling)
  • Home office (if required by employer and used exclusively for work)
  • Job-related education (to maintain skills, not to qualify for a new job)

How to claim: Complete a separate PA Schedule UE for each job/employer and enter the net amount on Line 1b of your PA-40. Spouses file separate schedules if both have expenses.

Other Deductions on PA-40 Line 10 (Schedule O)

These five deductions are claimed on PA Schedule O and entered on Line 10 of Form PA-40. The total cannot reduce your taxable income below zero.

Use the following codes on Line 10:

  • M – Medical Savings Account (MSA)
  • H – Health Savings Account (HSA)
  • S – Student loan interest
  • T – IRC §529 qualified tuition program contributions
  • A – IRC §529A Pennsylvania ABLE contributions
  • C – Combined (if claiming more than one)

1. Medical Savings Account (MSA) & Health Savings Account (HSA) Contributions

Deduct contributions that are allowable on your federal return. Limits follow federal rules (generally based on age, high-deductible health plan coverage, and family status).
Attach copies of your federal Form 1040 (Pages 1-2) and Schedule 1 when claiming these on Schedule O.

2. Student Loan Interest Deduction (New for 2025)

Up to $2,500 of interest paid on qualified student loans during 2025 is now deductible.

  • Applies to loans for attendance at eligible postsecondary institutions (U.S. Department of Education–approved).
  • Includes both required and voluntary payments.
  • Reported on Schedule O (Code S). You may need Form 1098-E.

This is one of the biggest 2025 updates for working families and recent graduates.

3. IRC Section 529 Qualified Tuition Program Contributions

Deduct contributions to any qualified 529 college savings plan (including Pennsylvania’s 529 College and Career Savings Program).
Limit: $19,000 per beneficiary per taxpayer (or per spouse on a joint return).
Married couples filing jointly can each claim up to $19,000 per beneficiary.

4. IRC Section 529A Pennsylvania ABLE Savings Account Contributions

Deduct contributions to a Pennsylvania ABLE account for individuals with disabilities.
Limit: $19,000 per beneficiary per contributor (aligned with the federal gift tax annual exclusion).

Important notes for both 529 and ABLE:

  • Only contributions made by December 31, 2025 qualify for the 2025 deduction.
  • Rollovers and beneficiary changes do not qualify.
  • Qualified distributions and certain employer contributions may also be excluded from PA taxable income.

Major 2025 Updates Affecting PA Taxpayers

  • New student loan interest deduction (up to $2,500)
  • $19,000 limit confirmed for 529 and ABLE contributions (matches federal gift tax exclusion)
  • Working Pennsylvanians Tax Credit (new refundable credit = 10% of your federal EITC, up to $805) – while technically a credit, it provides major relief for low- and moderate-income families.

Common Mistakes to Avoid

  • Claiming federal itemized deductions (mortgage interest, state taxes paid, charity) on your PA return—they are not allowed.
  • Forgetting to file Schedule O or UE when claiming deductions.
  • Exceeding the $19,000 per-beneficiary limit on 529/ABLE plans.
  • Including reimbursed expenses or personal commuting costs.

Tips to Maximize Your Pennsylvania State Tax Deductions

  • Contribute to a 529 or ABLE plan before December 31, 2025, to lock in the deduction.
  • Track every unreimbursed work expense throughout the year—Pennsylvania allows 100% of qualifying amounts.
  • Use the free myPATH account at revenue.pa.gov for easy filing and direct deposit.
  • If you qualify for the federal Earned Income Tax Credit (EITC), you automatically qualify for the new state Working Pennsylvanians Tax Credit.
