If I have a home office and I'm using the actual expense method but I find the depreciation part to make no sense with respect to the actual useful life of the asset.
So for example I purchased the installation of a new water heater. My home office uses a good portion of the house strictly for business use. The water heater is necessary and has business use. I already understand how the business use is allocated based on space used for business divided by the entire house square footage.
My question relates to adding assets for a home office. The TurboTax software assigns a 39 year straight line depreciation for the asset. This makes no sense because the water heater is not going to last 39 years. So I will never be able to fully depreciate the business use portion of this newly installed asset based on the TurboTax software. Why is TurboTax doing it this way ? and why can't I use a section 179 deduction for the business portion of the water heater ?
