Not sure if this is directed at me, but I'll answer what happened in my case. When my tax prep person filed for the year I transferred to my company's local branch, they asked him why didn't I file a return the year prior. There was no notice, it was triggered by the filing of the return after I transferred to our Taiwan branch. At that point he couldn't purger himself (or whatever you want to call it), so I had to provide prior year proof of income (my home country tax return) and they figured what I owed Taiwan on a prorated basis after that. If you claim no income, you need to PROVE it. Otherwise they do some calculation as mentioned above.
To the other OP claiming you can "just not claim it" that would be a very bad idea in the situation we are talking about. Again, you need to prove you had zero income and how you were sustaining yourself here for over 90 days. If you can't sufficiently do that, they will factor something that likely won't be in your favor. Again, if you never end up working for a local company OR have plans to someday work for a local company, then yes, they would likely never know. So sure, take a chance, ymmv. They have threatened in the past to audit those who stay here over 90 days in a year who haven't filed a return, been in the news a couple of times and linked in other threads here.
In the end I made my company pay the unexpected tax bill since the only reason I was here was for project work on their behalf and the only reason I was being made to pay is because I had now transferred to their local office in Taiwan.
