Berlin has the disadvantage of historically being an enclave of Western Germany in the communist GDR, very hard/expensive to supply as a result and always at risk of the commies forcibly annexing it. No large (and thus: tax-paying) company wanted to set up its headquarters there for that reason, and additionally as it was an enclave there was no place for industry to set up production facilities.
Nowadays, Berlin has a shit ton of "startups" HQ'd there, but they pay barely any taxes compared to production industry heavyweights.
