Field help: Job-related share (according to separate list)

Please enter the actual proportion of work-related use that you previously calculated. To do this, please itemise the work-related and private proportions of your telephone and internet use in a separate list, for example by:

• Itemised bills: Note the calls you make for business purposes and their duration.
• Internet usage log: Keep a record of how often you use the internet for work purposes and for what over a representative period (e.g. three months).
• Percentage estimate: If it is not possible to record this precisely, you can make a well-founded estimation (e.g. "approx. 60% for work").

Important: This list should be as specific as possible and should be supported by invoices, itemised bills or a written statement of use to make the information comprehensible.
