<prompt> Human: I currently work in Philly, but live in DE. I asked to be transferred to my firms DE office, and the compromise that was eventually agreed to is I work three days a week in DE and two days a week in Philly. This will save me 204 monthly on a train pass, and for the days I travel to Philly, I will get reimbursed for the train fare those days. As I work full time in Philly now, I pay Philly city tax, which comes to about 110 a month. The woman in charge of payroll says she cant advise where to say whether I work out of Philly it DE. Id prefer to say I work out of DE to avoid the city wage tax. Does anyone know if thats ultimately acceptable legally? To work 3 days to 2 days, DE vs Philly, and calling DE my home base?  <response>: If you are working in Delaware most of the time and being reimbursed on travel expenses to the Philly office, its probably OK to have your work address listed as Delaware.Where in Delaware is the office? Dont forget that the City of Wilmington also has a wage tax, although only 1.25. You can be reimbursed for days that you dont work in the city office. You would need to keep a spreadsheet of exact days you worked in Philly or elsewhere and the form is a real PITA on purpose, so they can reject you the first time.
