1099 Contractor in Indiana with a Pennsylvania Client: Where Do You File?
Answer
Indiana always, Pennsylvania sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Indiana through the year, and file a Pennsylvania nonresident return for any income from work you physically performed in Pennsylvania, claiming the credit back on the Indiana return.

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Pennsylvania is measured in days on the ground rather than in invoices sent.
Pennsylvania publishes no de minimis day count or dollar floor for nonresidents. Any Pennsylvania-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the Pennsylvania Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in Indiana and my client is in Pennsylvania. Do I have to file a Pennsylvania tax return?
Indiana always, Pennsylvania sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Indiana through the year, and file a Pennsylvania nonresident return for any income from work you physically performed in Pennsylvania, claiming the credit back on the Indiana return.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether Indiana and Pennsylvania hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
