Of course the system was delayed.. by years... And there were fewer experienced employees available because the lay-off policy was to let people retire as normal, but just stop hiring.
When the system finally was released, the tax collection service was in dire straits. Layoffs had continued, experience was lost. Employees were doing the work of 3 people without really knowing how and having noone to ask for advice. To top it off, it was politically decided to decentralise the tax collection service and split the offices into many small units across the country. Causing even more people to quit.
This isn't the end though. The system was released all right, but it was quickly discovered that it was making illegal tax collections from citizens due to faulty property evaluation. Attempts were made to fix the system, but it was SCRAPPED AFTER TWO YEARS.
Now we are left with a broken tax collection agency which cannot perform its duties and lacks manpower to verify tax claims from companies knowingly exploiting the situation.
