You can claim all work related expenses on your PA taxes if you have receipts. Examples of work related expenses that you can claim include union dues, licenses, tools, special clothing for work such as work boots. Basically anything that is required to do your job but would not be used outside of work. For example, you can claim a special work uniform or shoes if they would not be normally worn outside of work. You cannot claim a nice dress or suit and tie since they could easily be used outside of work.
