While navigating to a fix ATC inquired as to where we were navigating. I responded direct to the fix ZZZ1. Our FMS showed us 2 miles south. ATC came back and said we were in fact 12 miles from ZZZ1  so at that point I knew our GPS wasn't working. I asked for vectors to the airport and they were provided. Upon an uneventful landing our GPS still showed us 34 miles from the airport when we were sitting on the ramp.
A Pilot reported receiving false information from their GPS.
