The law requires that your cash register can be checked at any time. Keeping a cash book in a timely (daily!), regular and orderly manner is therefore mandatory because it helps the auditors to understand how your cash income and expenses are made and what exactly the cash movements in your cash register look like. It is therefore a necessary component in order to minimize the risk of additional estimates during a tax audit as much as possible.
