It's all relative. In the most simple case there is no reason (and no requirement) to file a tax report at all. Adding information from the employer is data that the employer has already submitted. Investment data could be transmitted from banks to the tax office directly, instead it's paper, as it always has been for the traditional process. The only iformation that would require filing is such not created through parties that are transmitting data anyway. e.g. private loans, collecting rent, etc. As soon as any information is required to be transmitted, all information is required. It's a process designed for execution on paper put into a computer. It's not a process designed for full automation. If any private company would operate that way they wouldn't be making any money.
