it comes back to the "keeping others down" mentality, since our tax consultant heard i was getting his services cheaper elsewhere, he most likely tipped the authorities for something bogus either as scare tactics or to actually do harm to my business.
i know it's him because he ranted about this service, said should be illegal to charge so little to handle taxes, and warned my mother that tax returns will be less or something because our situation isn't fully handled by him (completely false).
we pay him around 800€ per year, plus a fixed per tax return form (around 150€), and opening my business with him would have been around 700€ yearly plus 300€ once to handle some documents (it's free if you do it yourself).
i pay around 300€ every year for a service that so far was perfect, with online guides, a billing/management software, multiple tax consultants handling tickets and responses to any questions i might have.
you can see the convenience from a mile away, and he would be forced to innovate in a fair market; however the easiest (and most italian) way of handling competition is to be vicious about it, bring others down and leverage authorities
