We never say that sort of thing here.

Please start by telling us how far you have got. Can you take the tax details from the keyboard?

Jano,
As far as adding a field, can you show what you have so far? Their are different technologies you could be using within Java so that's to vague to answer.

For Excel, I recommend using the POI library if you need formatted Excel. If it is just CSV (common separated values) format, you can use pure Java.
