In Mexico we have a quasi-blockchain quasi-smart_contract that gets signed and sent to the taxman every time an invoice is created. This “contracts” are in xml format, require a private key to be signed, and are incredibly rich in catalogs and features. They are massive: just last year, over 10^10 generated documents were reported. Sure there is still a lot of informality, but in a matter of years not only will tax returns be automatically calculated for you to pay (this is already happening), but also p&l’s and balance sheets of small and big companies. This all happens on almost real time, by the way.
