Please Note: Some web browsers attempt to open PDFs with their own reader, which may remove interactive functionality from PDF Fill-In forms. It is strongly recommended that you right-click the links for these forms and select the "Save As..." option to download them. On your computer, open them with Adobe Reader so that they will function correctly. Broken links can be reported to webadmin@warren.org.

Also, please note that certain fields in PDF Fill-In forms can't be typed in. Instead, they calculate automatically as you fill in the form. For example, on the Warren City Income Tax Return Form, the field labeled "Total Warren Income Tax Withheld" will automatically calculate based on the amounts you enter in the fields just above it.
