Which IRS office do you send your return if you live in PA?

If you live in Pennsylvania and are sending your federal tax return to the IRS, you should mail it to the address specified for your filing status on the IRS website or in the instructions that accompany the tax forms. Generally, for most individual taxpayers, returns are sent to the Philadelphia, PA processing center. Always check the most current IRS guidelines, as mailing addresses can change based on the form type and whether you're including a payment.
