This study applies when buying a commercial building.
Generally, when you buy a commercial building, the cost of the building is written off over 39.5 years. That’s a long time, meaning you can only write off roughly 140 of the amount paid each year, and you must take that over 40 years. However, if you get a qualified engineer to come in and look at the different components in a building, you may be able to speed this up substantially.
For instance, when you buy a building, you typically include things like an HVAC system, special electrical setups for computers, and other things such as commercial range fans, parking lots, etc.
All of these items can be deducted a lot quicker and can often be written off 100% in the year in which you purchased the building. The key is to have a cost segregation study done by a qualified engineer before you can take these wonderful deductions.
