Do the tax rates sometimes differ between where I live and where I work?

Yes. Some taxing jurisdictions impose a workplace location, or non-resident earned income tax on those who work within their borders but who do not live there. If the tax rate where you work is higher than the tax rate where you live, your employer is required to withhold at the higher of the two rates. You are not entitled to receive a refund on this non-resident earned income tax withholding.

If you file online, Keystone’s e-file will determine your resident and workplace location rates based on your employer withholding from your W-2.
