Where you live, where you work and how you earn all change your Philadelphia position. Bring your Pennsylvania return, any city notices and records of tax paid elsewhere.
BIRT has separate gross receipts and net income components. The former $100,000 exemption has been removed, so review your position even if you previously owed nothing.
Official BIRT guidanceSelf-employed or in partnershipAsk whether Net Profits Tax applies alongside your other business filings, and how any available credits interact with the rest of your city calculation.
City business taxesCommuting across linesLive in Cherry Hill and work in Center City, or the other way round? Bring both addresses, work location records and pay statements so withholding and credits can be checked.
City income taxesCity residents with investmentsCertain investment income is reportable to the city by residents. Your federal return alone will not tell you whether this one applies to you.
City tax resourcesFiling dates and payment dates are not always the same thing. Confirm which applies to each return you are responsible for.
The city lists April 15 as the annual deadline covering the previous calendar year of business activity. Estimated payment requirements and exceptions need a separate look.
Check city filing guidanceA federal filing extension does not extend the time to pay. Ask about your return deadline and any outstanding balance now rather than when the extension runs out.
Check IRS extension guidanceGeneral information, reviewed September 2026. Holidays, relief provisions, tax year and individual circumstances all affect deadlines. Confirm your federal, Pennsylvania and city requirements separately.
You do not need every answer before you get in touch. Start with whatever needs resolving.
Income, a business, a property, a move or a notice from an agency. Mention any approaching deadline at the start so it shapes everything after it.
We confirm which filings and services you need, the records required and the fees, all before any work starts. No surprises at the end.
Prior returns, income documents, business records and notices. Ask for secure document sharing instructions, and please do not send tax documents by ordinary email.



The office is in Center City, but the work is not. Tell us where you live and where you earn, because in this city those two answers can pull in different directions.
Plenty of our Philadelphia work starts outside the city line. If you commute in from Montgomery, Bucks, Delaware or Chester County, or over the bridge from Cherry Hill, Haddonfield, Collingswood or Moorestown, the Wage Tax and the Pennsylvania and New Jersey reciprocal agreement both need looking at before anyone touches a return. Worth going through once with a tax advisor, properly, rather than guessing at it every April.

Please get in touch before you travel so we can confirm the meeting format and appointment arrangements. Most of our tax preparation work is handled remotely if that suits you better.
