Hi All,
Don't know much about this as I live in the UK..... but over here if you run a business from home you can claim the grand amount of £3.00 ($4.50) per week against your profits for using you home. You cannot claim a telephone unless it is only used for business and this is the same for all other equipment.
The only thing I know for sure is that whatever government it is.... it will get ya!!!!!!!
Hugs
Caroline
