If you live in Chester County, you owe a local earned income tax on your wages and self-employment profits, generally totaling about 1% once the municipal and school district portions are combined. Returns are filed annually with Keystone Collections Group, the designated collector for the county, and the deadline is April 15 of the year following the income year.1Chester County Tax Collection Committee. Keystone Collections Group You file even if your employer withheld the full amount from your paycheck.
What Income Is Taxed
The tax hits money you actively earn. Wages, salaries, commissions, bonuses, tips, and incentive pay all count. If you run a business or freelance, your net profits are taxed the same way.
Passive income is left alone. Interest, dividends, capital gains, Social Security, and pension payments are excluded. So are unemployment compensation, workers’ compensation, and disability payments.2Pennsylvania General Assembly. Pennsylvania Code – Local Tax Enabling Act
The rule of thumb is simple. If you worked for it, it’s taxable. If it came from investments, benefits, or retirement accounts, it’s not.
Your Rate and PSD Code
Pennsylvania’s local earned income tax is residency-based, with one wrinkle. If the non-resident rate at your workplace is higher than the total resident rate where you live, your employer withholds at the higher rate, and the difference goes to the work municipality.3Pennsylvania Department of Community and Economic Development. Local Withholding Tax FAQs Most Chester County communities land near 1% combined, split between the municipality and the school district, though exact rates vary by local budget decisions.
Every address in Pennsylvania sits inside a six-digit Political Subdivision (PSD) code. The first two digits identify the county, the first four identify the school district, and all six pinpoint the municipality.4Pennsylvania Department of Community and Economic Development. PSD Codes and EIT Rates You need the code for your home and for your workplace. The state’s Municipal Statistics tool returns both the PSD code and the current rate when you enter an address.5Pennsylvania Department of Community and Economic Development. Municipal Statistics – Find Local Withholding Rates by Address
Getting the PSD code right matters. A wrong code routes your money to the wrong jurisdiction, and sorting it out afterward can take months.
Who Has to File
Every Chester County resident with earned income has to file a local return by April 15, even if the full amount was already withheld by an employer. The return reconciles what was withheld against what you actually owe, which matters when you changed jobs, had side income, or lived at an address with a different rate than your employer used.
Under the Local Tax Enabling Act, municipalities can choose to exempt residents whose total income from all sources falls below $12,000.2Pennsylvania General Assembly. Pennsylvania Code – Local Tax Enabling Act Whether your municipality adopted that exemption depends on local ordinances, so ask Keystone if you think you qualify.
Before you file, pull together your W-2s (local wages are in Box 18, local tax withheld in Box 19), any 1099-NEC forms and PA Schedules C, E, F, or K-1 for self-employment income, PSD codes for home and workplace, Social Security numbers for you and any spouse, and documentation of tax paid to Philadelphia or any out-of-state jurisdiction.6Centre Tax Agency.

Credits for Philadelphia and Out-of-State Work
Chester County sits close enough to Philadelphia and Delaware that many residents already pay income tax somewhere else. Pennsylvania doesn’t let you be taxed twice on the same wages, but claiming the credit takes a few specific steps.
Philadelphia Wage Tax
If you work in Philadelphia and your employer withholds the Philadelphia wage tax, you can apply that amount as a credit against your Chester County EIT. Report it on Line 12 of the annual return and attach the W-2 showing Philadelphia tax withheld. The credit can’t exceed your local EIT liability, can’t be transferred to a spouse, and can’t be carried forward.7Keystone Collections Group. How Do I Receive Credit for the Wage Tax I Paid to Philadelphia? If you paid Philadelphia more than your Chester County liability, the overage isn’t refundable through the local return.
Out-of-State Work
Pennsylvania has reciprocal agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia.8Pennsylvania Department of Revenue. How Does Working in a Reciprocal Agreement State Effect My State Income Tax? You owe state income tax only to Pennsylvania. If an employer in one of those states withheld their state’s tax by mistake, request a refund from that state and pay Pennsylvania directly.
Non-reciprocal states take an extra step. If you work in a place like Wilmington, Delaware and pay local income tax there, you can credit it against your Chester County EIT. But any out-of-state income tax has to be credited against your Pennsylvania state tax first. Only what remains after that can offset your local EIT.9Keystone Collections Group. Out-of-State Tax Credit for Pennsylvania Resident Local Tax Liability The credit applies only to income taxed in both places, and it can’t exceed your local liability.
How to File and Pay
Keystone Collections Group processes all Chester County returns and offers electronic filing through its online portal.1Chester County Tax Collection Committee. Keystone Collections Group E-filing gives you an immediate confirmation number, which is your proof of timely submission. Paper returns go to Keystone’s processing center with copies of your W-2s and supporting schedules.
If you owe, an electronic bank transfer is the cleanest payment method. Credit card payments usually carry a convenience fee in the 2% to 3% range. Check or money order works for paper filers. Whatever method you use, the full balance is due April 15.
If you’re owed a refund because your employer over-withheld, Keystone will either mail a check or roll the amount into next year’s liability. Spring processing typically runs four to eight weeks, so hold on to your confirmation number or certified mail receipt.
Penalties and Interest for Late Payment
Missing April 15 triggers both a penalty and interest. The penalty runs 1% per month on the unpaid tax, capped at 15% of the original amount owed.10Keystone Collections Group. How Is the Penalty and Interest Accrual Calculated for Earned Income and Local Service Taxes? Interest accrues on top of the penalty at a statutory rate set under the Local Tax Enabling Act. These charges apply whether you filed late, paid late, or both.
If you can’t pay the full amount, file on time and pay what you can. Doing nothing is always the more expensive option.
Extensions
You can request more time to file, but an extension only pushes the filing deadline, not the payment deadline. Interest and penalty still run on any unpaid balance after April 15.11Pennsylvania Department of Revenue. Extension of Time to File
If you already have a federal or state extension, send a copy to Keystone Collections Group along with an estimated payment by April 15, and confirm with Keystone that the extension is on file. The common mistake is filing the extension without any payment, because the extension never stops the clock on what you owe.
