How do I calculate the "Depreciation Expense" portion, that is required by my state of PA, for a home office?

[Zbucklyo · Accepted solution]

It is part of the federal tax process, where you describe the home office for the first time - the essential information required is the square footage of the office, square footage of the entire home, cost basis for the home, split into a structure value and land value.  The depreciation for the home office is derived from that information.
