Understanding philly income tax is essential if you live or work in Philadelphia—it’s one of the highest local income tax rates in the country, and most people don’t realize how much they’re actually paying. Whether you’re a W-2 employee, self-employed, or a business owner, the City of Philadelphia levies a local income tax on top of federal and Pennsylvania state taxes, and the numbers can add up quickly. The good news? There are legitimate strategies to reduce what you owe, and this guide will walk you through everything you need to know to keep more money in your pocket in 2024.

Philly Income Tax Basics
Philadelphia’s local income tax is separate from Pennsylvania state income tax and federal income tax. It applies to residents and non-residents who earn income within the city limits. The tax is administered by the Philadelphia Board of Revision of Taxes, which handles assessment, collection, and appeals.
Here’s what makes philly income tax different from what you might pay elsewhere: it’s a flat tax, not progressive. Everyone pays the same rate regardless of income level. This means a teacher earning $40,000 and a surgeon earning $400,000 pay the same percentage. The city considers this fair because it’s based on the principle that all residents benefit equally from city services.
The tax applies to wages, salaries, net business income, and certain investment income. If you’re a resident working in Philadelphia, you pay on all income. If you’re a non-resident working in the city, you only pay on income earned within Philadelphia’s boundaries. This distinction matters significantly for your tax planning.
Current Tax Rates & Brackets
As of 2024, Philadelphia’s local income tax rate stands at 3.8712% for residents. This is one of the highest local income tax rates in the United States—higher than cities like New York (3.876%) and significantly higher than most other major metros. For non-residents, the rate is the same, but it only applies to income earned within Philadelphia.
To put this in perspective: if you earn $50,000 in Philadelphia as a resident, you’ll owe approximately $1,936 in local income tax alone, before federal and state taxes. That’s substantial, and it’s why many Philadelphia workers actively look for ways to reduce their taxable income.
The city also taxes net business income at the same rate. If you’re self-employed or own a business, you’re responsible for paying this tax on your net profits. Unlike federal taxes, there’s no self-employment tax component—just the flat 3.8712% rate.
Filing Deadlines & Requirements
Philadelphia resident income tax returns are typically due on April 15th, aligning with your federal tax deadline. However, if you file for a federal extension, your Philadelphia return is also extended to October 15th. Non-residents have the same deadline but only need to file if they had Philadelphia-source income.
You must file a Philadelphia return if you’re a resident with any taxable income, even if you don’t owe federal taxes. This catches many people off guard—you could have zero federal liability but still owe Philadelphia income tax. The city is strict about this requirement, and penalties for late filing can reach 10% of the tax owed.
Most employers automatically withhold Philadelphia income tax from paychecks, similar to federal withholding. If you’re self-employed, you’ll need to handle estimated payments yourself. We’ll cover PA estimated tax payments in detail below, but the key is staying ahead of your tax liability throughout the year.
Deductions & Tax Credits
Philadelphia allows fewer deductions than federal taxes, which is one reason the local rate stings more. You cannot use the standard deduction or itemized deductions for philly income tax. Instead, the city allows specific deductions that reduce your taxable income:
Standard deductions vary by filing status: Single filers get a $15,000 deduction, married filing jointly get $30,000, and heads of household get $22,500 (these amounts are for 2024 and may change annually). These deductions are significantly lower than federal standard deductions, which means you’re paying tax on more of your income.
Beyond the standard deduction, Philadelphia allows deductions for contributions to retirement plans like traditional IRAs and 401(k)s. This is one of your biggest opportunities to reduce taxable income. If you can contribute to a pre-tax retirement plan, you’ll reduce both your federal and Philadelphia income tax liability.
The city offers limited tax credits. The Philadelphia Earned Income Tax Credit (EITC) mirrors the federal credit and provides relief for lower-income working families. If you qualify for the federal EITC, you likely qualify for the city version as well.
Self-Employed Savings Strategies
If you’re self-employed in Philadelphia, you have more control over your tax liability—and more responsibility. Unlike W-2 employees who have taxes withheld automatically, you must manage your own payments and deductions. This is where professional guidance often pays for itself.
Your biggest opportunity is maximizing business deductions. Home office expenses, equipment, software, professional development, and health insurance premiums are all deductible. Many self-employed people leave money on the table here. Keep meticulous records of every business expense; the IRS and Philadelphia tax authorities both scrutinize self-employment income closely.
Consider a Solo 401(k) or SEP-IRA if you have self-employment income. These allow you to contribute significantly more than a traditional IRA—up to $69,000 in 2024 for a Solo 401(k). Every dollar you contribute reduces both your federal and Philadelphia taxable income. For a Philadelphia resident in the 24% federal bracket plus 3.8712% local tax, a $10,000 contribution saves you approximately $2,787 in total taxes.
Quarterly estimated tax payments are non-negotiable for self-employed Philadelphians. The IRS requires estimated payments, and so does Philadelphia. Failing to make them results in penalties and interest. We recommend using accounting software or working with a CPA to calculate your estimated liability accurately.
Residency & Non-Resident Rules
Philadelphia’s definition of residency for tax purposes is straightforward: if you live in the city on December 31st of the tax year, you’re a resident for the entire year. This means if you move to Philadelphia on December 30th, you’re a resident for that entire tax year. Conversely, if you move out on January 2nd, you’re not a resident for that year.
Non-residents who work in Philadelphia only pay the 3.8712% tax on income earned within the city. If you earn $40,000 in Philadelphia and $20,000 elsewhere, only the $40,000 is subject to Philadelphia income tax. This distinction makes a real difference for people living in surrounding suburbs who commute into the city.
If you’re a business owner with a Philadelphia office or clients, the residency rules become more complex. You may need to apportion your income based on where it’s earned. This is where professional help becomes valuable—misclassifying your residency status can trigger audits and penalties.
Estimated Tax Payments Guide
Self-employed people and those with significant non-wage income must make quarterly estimated payments to Philadelphia. The payment due dates are April 15, June 15, September 15, and January 15 of the following year. Missing even one payment triggers penalties, so calendar these dates.
To calculate your estimated payment, you need to project your annual Philadelphia-source income and apply the 3.8712% rate. Divide by four for your quarterly payment. If your income fluctuates throughout the year, adjust your payments accordingly. The city allows you to pay different amounts each quarter—you don’t have to pay equally.
Many self-employed people underestimate their liability because they forget to account for Philadelphia tax on top of federal and state taxes. Your total tax burden in Philadelphia is significant: federal (up to 37%), Pennsylvania state (3.07%), and Philadelphia local (3.8712%). For someone in the 24% federal bracket, total marginal tax rates exceed 30%. This is why maximizing deductions and credits matters so much.
You can make estimated payments online through the Philadelphia tax website or by mail. We recommend online payment for the paper trail and confirmation. Keep records of every payment—these are your proof if questions arise during an audit.
Avoid These Common Mistakes
Mistake #1: Forgetting Philadelphia tax exists. Many people focus on federal and state taxes and overlook the local component. This is costly. Set up a separate savings account for Philadelphia taxes so you’re not caught short at tax time.
Mistake #2: Misclassifying residency status. If you moved during the year, verify your filing status carefully. Claiming non-resident status when you’re actually a resident is fraud and triggers penalties plus interest.
Mistake #3: Not tracking business deductions. Self-employed people often lose deductions because they don’t keep records. Home office, mileage, supplies, professional services—if you don’t document it, you can’t deduct it. Use accounting software like QuickBooks or Wave to track expenses in real-time.
Mistake #4: Ignoring retirement contributions. Contributing to a traditional IRA or 401(k) reduces your Philadelphia taxable income. Many people max out federal retirement contributions but don’t realize they’re also reducing local tax liability. This is free money—use it.
Mistake #5: Not filing when you think you don’t owe. Even if you expect a refund or zero liability, Philadelphia requires you to file. Penalties for non-filing are steep, and you could lose refund money if you don’t file.
When to Get Professional Help
You should consider working with a CPA or tax professional if you’re self-employed, own a business, have multiple income sources, or your income exceeds $100,000. Philadelphia tax situations can get complicated quickly, and professional guidance often saves more than it costs.
A good tax professional will review your situation, identify deductions you might miss, and ensure you’re compliant with all Philadelphia requirements. They can also represent you if the city audits your return. Given the stakes—penalties, interest, and potential legal issues—professional help is an investment, not an expense.
If you use AI accounting software for taxes, choose one that specifically handles Philadelphia income tax. Not all tax software platforms include local taxes, so verify before you buy.
For appeals or disputes with the Philadelphia Board of Revision of Taxes, professional representation is almost essential. The board hears hundreds of cases, and they’re experienced in identifying weak arguments. Having a CPA or tax attorney in your corner significantly improves your odds.
Frequently Asked Questions
Do I have to pay Philadelphia income tax if I work remotely?
If you’re a Philadelphia resident, yes—you pay on all income regardless of where you work. If you’re a non-resident working remotely for a Philadelphia company, the answer depends on where your employer is located and how they classify the income. Generally, non-residents only pay on income earned within Philadelphia’s boundaries. Consult a CPA to determine your specific situation, especially if your employer is in the suburbs but the work is performed remotely.
What’s the difference between Philadelphia and Pennsylvania income tax?
Philadelphia is a local tax administered by the city, while Pennsylvania is a state tax administered by the Pennsylvania Department of Revenue. Pennsylvania’s state income tax rate is 3.07%, which applies to all residents regardless of where they live in the state. Philadelphia’s 3.8712% rate applies only to residents and non-residents earning income within the city. You pay both, plus federal taxes. Together, the combined local and state rate in Philadelphia is 6.9412%, one of the highest in the nation.
Can I deduct Philadelphia income tax on my federal return?
Starting in 2018, the federal tax code limited the deduction for state and local taxes (SALT) to $10,000 per year. This includes Philadelphia income tax, Pennsylvania state tax, and property taxes combined. For most Philadelphia residents, this cap means you can’t fully deduct all your local taxes on your federal return. This is a significant impact on high earners, so factor it into your tax planning.
What happens if I don’t file a Philadelphia return?
The city takes non-filing seriously. You face a penalty of up to 10% of the tax owed, plus interest accruing daily. If you owe $1,000 and don’t file for two years, you could owe $1,200+ just in penalties and interest. The city also has enforcement tools—they can place liens on your property, garnish wages, or suspend your business licenses. File on time, even if you think you don’t owe anything.
Are there any Philadelphia tax credits I’m missing?
The main credit available is the Philadelphia Earned Income Tax Credit for low-income workers. High-income earners have fewer options. However, maximizing retirement contributions is often more valuable than chasing credits. A $10,000 401(k) contribution saves you more in taxes than most available credits. Work with a professional to ensure you’re optimizing your situation.
How do I appeal a Philadelphia tax assessment?
You can appeal through the Philadelphia Board of Revision of Taxes. The process involves filing a formal appeal within a specific timeframe and presenting your case. Having professional representation significantly improves your chances. The board is more likely to side with taxpayers who have documented evidence and professional advocates. Don’t attempt this alone if the amount is significant.
Do I need to file Philadelphia taxes if I only worked part of the year?
Yes. If you had any Philadelphia-source income during the year and you’re a resident, you must file. Even if you only earned $500, the requirement applies. Non-residents must file if they had Philadelphia-source income. There’s no minimum income threshold for filing requirements in Philadelphia, unlike some other jurisdictions.
What if I moved out of Philadelphia mid-year?
Your residency status is determined by where you lived on December 31st. If you moved out before that date, you’re a non-resident for the entire year and only pay Philadelphia tax on income earned within the city before you moved. If you moved out after December 31st, you’re a resident for the entire year. Document your move date carefully with utility bills, lease agreements, or other evidence.
Key Takeaways
Philadelphia’s income tax rate of 3.8712% is one of the highest in the country, and it adds up quickly. Understanding the rules, deadlines, and deductions available can save you thousands of dollars annually. The most impactful strategies include maximizing retirement contributions, carefully documenting business expenses if you’re self-employed, and verifying your residency classification.
Don’t overlook Philadelphia income tax in your overall tax planning. Many people focus on federal taxes and miss opportunities to reduce their local liability. Whether you’re a W-2 employee, self-employed, or a business owner, there are legitimate ways to keep more of your income.
If your situation is complex—multiple income sources, self-employment, or significant assets—invest in professional help. A CPA familiar with Philadelphia taxes can identify deductions you’d miss and ensure you’re fully compliant. The cost of professional guidance is almost always less than the taxes you’ll save.
Stay organized, file on time, and keep detailed records. The Philadelphia tax authorities are efficient at enforcement, so compliance is non-negotiable. But with proper planning and understanding of the rules outlined in this guide, you can minimize what you owe and keep more money in your pocket.
