Pennsylvania tax filing: file PA state taxes online, Form PA-40, deadlines and requirements

Do you have to file a Pennsylvania tax return?

Pennsylvania sets a very low bar. You must file a PA-40 for 2025 if you received more than $33 of total PA taxable gross income, which is the point at which $1 of tax is due, even if no tax is ultimately owed after withholding or credits. In practice, almost every resident with a job files.

You also file if you had a loss from any transaction as an individual, or if Pennsylvania tax was withheld and you want it back. Nonresidents file a PA-40 if they earned Pennsylvania-source income, and part-year residents file for the portion of the year they lived in the state.

Reciprocal states and who is exempt

Pennsylvania has reciprocal agreements with New Jersey, Ohio, Virginia, West Virginia, Indiana, and Maryland. A resident of one of those states who works in Pennsylvania is not subject to Pennsylvania income tax on those wages, and a Pennsylvania resident working in those states is taxed only by Pennsylvania. If your employer withheld the wrong state's tax, you file to sort it out. The state tax filing pillar lists the full reciprocity map.

Tax Forgiveness

Pennsylvania's Tax Forgiveness program, claimed on Schedule SP, can reduce or eliminate the tax for lower-income filers. A family of four can qualify with eligibility income up to roughly $34,250, and a single filer up to about $8,750, with a sliding scale above that. It is one of the few ways to lower a Pennsylvania bill, and it requires a filed return. The current rules are published by the Pennsylvania Department of Revenue.

The flat rate and the eight classes of income

Pennsylvania taxes income at a flat 3.07 percent, the second-lowest broad income tax rate among states that have one. What makes the PA-40 unusual is the structure underneath that rate. Pennsylvania sorts income into eight classes, and the rules for each class stand on their own:

1. Compensation (wages, salaries, tips)
2. Interest
3. Dividends
4. Net profits from a business, profession, or farm
5. Net gains from the sale of property
6. Net gains from rents, royalties, patents, and copyrights
7. Income from estates or trusts
8. Gambling and lottery winnings

A loss in one class cannot offset a gain in another. If your business shows a loss but you had wages, the loss does not reduce the tax on your wages. This is a real departure from the federal return, where income and losses mix more freely.

Pennsylvania also gives you no standard deduction and no personal exemption. The state does not tax Social Security, most retirement income, or unemployment compensation, which softens the picture for retirees, but for a working filer the taxable base is close to gross compensation. That is why the effective burden can feel higher than 3.07 percent once local tax is added.

Pennsylvania local earned income tax and the Philadelphia wage tax

This is the part first-time Pennsylvania filers miss. The 3.07 percent state tax is not the whole story. Under Act 32, nearly every municipality and school district levies a local earned income tax (EIT) on residents, and often on people who work there. The combined resident rate is commonly around 1 percent, though it ranges higher depending on where you live.

Philadelphia is the big exception. Instead of the roughly 1 percent local EIT, the city runs its own wage tax near 3.75 percent on residents and about 3.44 percent on nonresidents who work in the city, and the exact rate is adjusted periodically. That single city tax is larger than the state tax. The local EIT is filed and paid separately from the PA-40, usually through a regional collector such as Berkheimer or Keystone, and Philadelphia handles its own through the city. Your PA-40 does not settle it.

TaxFile prepares your Pennsylvania state PA-40. The local earned income tax return is a separate filing with your local collector, so budget for it and keep your pay stubs, which usually show the local tax already withheld. Confirm your municipality's rate through the state DCED lookup.

Pennsylvania tax filing deadline, extension and filing online

Pennsylvania's extension is tied to the federal one. If you have a valid federal extension (Form 4868) and you do not owe Pennsylvania tax, your state extension to October 15, 2026 is automatic and you attach nothing extra. If you owe a Pennsylvania balance, or you do not have a federal extension, file Form REV-276 by April 15 and pay what you owe. As everywhere, the extension moves the filing date only. Interest runs on unpaid tax from April 15.

Filing electronically is the practical default, and it draws on your federal figures. TaxFile prepares both returns from one pass:

• Upload or talk. Drop in your W-2s and 1099s and it reads them, or describe your year and it asks what it needs.
• Federal and Pennsylvania together. One set of documents produces both returns, with income sorted into the correct Pennsylvania classes.
• Tax Forgiveness checked. It tests Schedule SP eligibility, one of the few ways to lower a Pennsylvania bill.
• Error check, then you approve. Inconsistencies are flagged and nothing is e-filed until you review and approve every line, through an authorized IRS e-file provider.

Pricing is $39 simple, $89 self-employed, $199 business, plus $19 per state return. There is no free tier, and the state return does not include your separate local earned income tax filing. If your Pennsylvania income comes from contract or freelance work, self-employed tax filing covers Schedule C and Schedule SE in more detail. TaxFile does not e-file federal extensions or prepare amended returns, and does not handle capital gains on Schedule D, rental income on Schedule E, or cryptocurrency. TaxFile is self-prepared tax software and does not provide personalized tax advice, and no refund amount is guaranteed.
