Tax Year 2020 - I am claiming the use of my home office this year for the first time. How do I know the cost of land?

[JoannaB2]

It depends.  You may find the cost of the land on your property tax statement or call your local property assessor's website or office. Generally, the price of raw land  is 3 percent of the home price, or 15 percent of the retail lot price.
