Turbotax say I owe PA State Income tax but as Active Duty Military my income is not taxable in PA. I need to correct my PA Tax due balance before I file.

Active duty military income earned outside of Pennsylvania by a Pennsylvania resident is not subject to Pennsylvania income tax. In the state section of TurboTax, when you come to the page titled “Compensation Summary”, click edit beside your military income.   Check the box to indicate that this income is not taxable to Pennsylvania.  This will flag your military income as not taxable in Pennsylvania. 

However, any interest, dividends, capital gains, rental income, etc  IS taxable by PA regardless of where you are stationed.

If you have already e-filed, you can submit copies of your military orders and an explanation of where you earned your active duty pay to:

PA Department of Revenue
Electronic Filing Section
P.O. Box 280507
Harrisburg, PA 17128-0507

Or FAX to:
717-772-4193

Please make sure your Social Security number is on your orders.
