To file a PA-40 Pennsylvania state tax return, report your income in each of the state’s eight taxable income classes, apply the flat 3.07 percent tax rate, subtract any credits and withholding already paid, and submit the return by April 15 through myPATH, approved tax software, or paper mail.1Pennsylvania Department of Revenue. Personal Income Tax Returns for tax year 2025 are due April 15, 2026.
Do You Have to File
Pennsylvania sets the filing threshold very low. If your total gross taxable income for the year exceeded $33, you must file a PA-40, even if no tax ends up being owed. You also have to file if you had a loss from any transaction as an individual, sole proprietor, partner, or S corporation shareholder, because the Department of Revenue needs that loss on record.2Pennsylvania Department of Revenue. Pennsylvania Personal Income Tax Return PA-40 Filing Requirements
Residency decides what Pennsylvania can tax. Full-year residents owe tax on all income, from inside or outside the state. Nonresidents are taxed only on Pennsylvania-source income. Part-year residents file as a resident for the months they lived in the state and as a nonresident for the rest.3Pennsylvania Department of Revenue. Brief Overview and Filing Requirements4Legal Information Institute. Pennsylvania Code 61 121.8 – Method of Taxing Part-Year Residents
What to Gather Before You Start
Pull together everything that documents income you received during the calendar year:
- W-2 statements from each employer
- 1099 forms for interest, dividends, and non-employee compensation
- Records of business income and expenses
- Records of property sales (stocks, real estate, other investments)
- Records of rents, royalties, and gambling or lottery winnings
- A copy of your federal return, since many figures carry over
Depending on your situation, you may also need supplemental schedules. Schedule SP is the one to grab if you might qualify for Tax Forgiveness. Schedule G-L covers a credit for income tax paid to another state. Schedule UE handles unreimbursed employee business expenses. If you earned wages in more than one state, pull the other state’s return as well, because you have to attach a copy to claim the resident credit.
Filling Out the PA-40
The form opens with identifying information for you and, if married, your spouse. From there, you report income in each of Pennsylvania’s eight separate classes:1Pennsylvania Department of Revenue. Personal Income Tax
- Compensation (wages, salaries, tips, bonuses)
- Interest
- Dividends
- Net profits from a business, profession, or farm
- Net gains from the sale or exchange of property
- Rents, royalties, patents, and copyrights
- Income from estates and trusts
- Gambling and lottery winnings, including Pennsylvania Lottery cash prizes
Each class is calculated on its own. One quirk catches people off guard: Pennsylvania does not let you use a loss in one class to offset income in another. If you lost money selling stock but earned wages, the stock loss cannot reduce your taxable compensation. This matters most for filers with business losses and W-2 income.
Once you have totaled each class, apply any eligible credits and deductions, then multiply your taxable income by 3.07 percent to get the tax owed. Compare that to what was already paid through employer withholding or estimated payments. If you overpaid, you get a refund. If you still owe, the balance is due with the return.
Three Ways to Submit the Return
Pennsylvania offers three filing methods:5Commonwealth of Pennsylvania. File a Pennsylvania Income Tax Return
- myPATH, the Department of Revenue’s free state-only e-file system. You can prepare and submit the PA-40 at no cost.
- Commercial tax software approved through the federal/state e-file program. Some vendors offer free filing for qualifying taxpayers; others charge.
- Paper return by mail. Print the completed PA-40 and send it to the correct address for your situation.
Providing your driver’s license or state ID number when filing electronically is optional, but it can speed up processing and adds fraud protection.
If you file on paper, the mailing address depends on the return’s financial outcome:6Pennsylvania Department of Revenue. Mailing Addresses
- Payment enclosed: PA Dept of Revenue, Payment Enclosed, 1 Revenue Place, Harrisburg, PA 17129-0001
- No payment and no refund: PA Dept of Revenue, No Payment/No Refund, 2 Revenue Place, Harrisburg, PA 17129-0002
- Refund or credit requested: PA Dept of Revenue, Refund/Credit Requested, 3 Revenue Place, Harrisburg, PA 17129-0003
Sending the return to the wrong address delays processing. Check the address against your return’s outcome before mailing.
Credits Worth Checking Before You File
Tax Forgiveness
Pennsylvania’s flat tax has no standard deduction or personal exemption. The Tax Forgiveness program serves that role for lower-income households, erasing anywhere from 10 to 100 percent of state income tax depending on your eligibility income and number of dependents.7Commonwealth of Pennsylvania. Tax Forgiveness
You claim it by completing Schedule SP, which calculates “eligibility income.” That figure is broader than taxable income and includes items like child support and public assistance. For tax year 2025 returns, the maximum eligibility income for 100 percent forgiveness is:
- Single filer, no dependents: $6,500
- Single filer, one dependent: $16,000
- Single filer, two dependents: $25,500
- Married filer, no dependents: $13,000
- Married filer, one dependent: $22,500
- Married filer, two dependents: $32,000
Each additional dependent raises the threshold by roughly $9,500. Partial forgiveness on a sliding scale is available if your income only slightly exceeds those limits. A married couple with two children earning up to $34,250 still qualifies for some percentage of forgiveness. Many eligible filers skip the credit simply because they do not know it exists.
Credit for Taxes Paid to Another State
If you live in Pennsylvania but earn income in another state, you can usually avoid double taxation through the resident credit on Schedule G-L. The credit equals the lesser of what you actually paid the other state on that income, or what Pennsylvania would charge on the same income at 3.07 percent.8Pennsylvania Department of Revenue. Deductions and Credits
You must attach a copy of the other state’s return and the corresponding W-2s. If you worked in multiple states, file a separate Schedule G-L for each one. The Department of Revenue will disallow the credit if the supporting out-of-state return is missing. The credit does not apply to income from foreign countries or to Pennsylvania-source income taxed by another state.
If You Can’t File or Pay by April 15
Pennsylvania grants up to a six-month extension. If you already have an approved federal extension on Form 4868 and owe no Pennsylvania tax, the state automatically grants you the same extension; just attach a copy of the federal extension when you eventually file.9Pennsylvania Department of Revenue. Application for Extension of Time to File REV-276
If you have no federal extension, or you owe Pennsylvania tax, file Form REV-276 before the original due date. You can also skip the paper form by making a credit card or ACH payment through the Department of Revenue’s online portal on or before April 15, which automatically triggers the six-month extension.
An extension gives you more time to file, not more time to pay. Any tax owed is still due April 15, and unpaid balances accrue interest and penalties from that date. Late filing without an extension triggers a 5 percent penalty on the unpaid tax, plus another 5 percent for each month the return remains unfiled, up to a maximum of 25 percent, with a $5 minimum charge.10Pennsylvania Code and Bulletin. Pennsylvania Code 61 121.26 – Penalties for Failure to File or for Filing a Late Return
If you can file but cannot pay the full balance, the Department of Revenue offers payment plans. A standard plan covers balances under $50,000 and must be paid within 12 months. Larger balances or longer timeframes require additional review. All prior-year returns must be filed before the department will set up any plan, and current-year plans cannot be established until after the filing deadline.11Commonwealth of Pennsylvania. Personal Income Tax Payment Plans
Pennsylvania accepts payment online through myPATH by credit card, debit card, or direct bank withdrawal; by phone through ACI Payments at 1-800-272-9829 using jurisdiction code 4800; or by mail with a check or money order and the appropriate payment coupon.12Commonwealth of Pennsylvania. Make a Personal Income Tax Payment
After You File
You can check refund status through the tracking tool on myPATH using your Social Security number and the exact refund amount from your return.13Commonwealth of Pennsylvania. Track Status of Pennsylvania Income Tax Refund E-filed returns typically take about four weeks to process; paper returns take eight to ten. Direct deposit is the fastest way to receive your money.
If you find an error after filing, correct it with an amended PA-40 and Schedule PA-40 X. The schedule is not a standalone form; it accompanies a full PA-40 marked as amended. You have three years from the original due date to amend. Include only the documents that changed, and write “Amended” at the top of every revised schedule. If you are close to the three-year deadline, the department recommends filing a Petition for Refund (REV-65) instead, which carries stronger appeal rights.14Pennsylvania Department of Revenue. Instructions for Schedule PA-40 X Amended Pennsylvania Personal Income Tax Schedule
Don’t Forget the Local Return
Filing the PA-40 does not satisfy your local tax obligation. Pennsylvania law requires every resident with earned income or net profits to also file an annual local earned income tax return with the collector assigned to your home municipality, even if your employer already withholds local tax from your paycheck.15Keystone Collections Group. Am I Required to File a Local Tax Return Even if My Employer Withholds the Tax From My Paycheck Local rates vary by municipality and school district, and the deadline typically matches the state’s April 15 date.
