Haven't read all of the replies.
Just based on post title I would say, sure, most tinnitus are psychosomatic, which means neurologic, it is the same thing, just like anxiety , it is neurological in its manifestation with, most times, a strong psychological part in its causes.
Your IBS example is spot on. But we could even better take in example headaches (all of them wether it is migraines, which is a specific subset, or common tension headache etc), all the most recent research point to a neurological disfunction often driven by a psychosomatic/emotional stressors cause. Sure there are exceptions, in fact headaches are divided in primary and secondary, the latter are from an underlying problem like physical trauma, neoplasia and so on, of course this secondary headaches are far more rare than primary ones, while primary ones are EXTREMELY common ( at least in it's sporadic form). I strongly believe it is the same for Tinnitus. And, just as tinnitus, headaches (the more it is mild the less symptoms you have) have a host of neurological symptoms i.e. aura, nevralgia, ear fullness, sensory sensitivity (lights, sounds, smell), muscle tension in neck/head, pain, nausea, head pressure. Sounds familiar ? Although many symptoms are different, some overlap with those that someone with tinnitus could experience, that is because headaches and tinnitus are "usually" a symptom of a neurological imbalance, and if it holds true for headaches I would guess that one of the major cause is an emotional dysfuncion (be careful, altought it is best described this way because it usually precede and creates the snowballing effect that gives rise to a variety of symptoms, it is absolutely neurological in its manifestation, I mean, it's a real biologic dysfunction. The good news is that unlike degenerative neurological conditions, emotional-neurological disturbances, even it's not easy at all, can be managed and are sometime reversible, specially if psychological issues play a big part in its aetiopathogenesis).
