In the old days, when you bought a $700 computer, you potentially were forced to depreciate that computer over 5 years. These days, you can immediately expense all business asset purchases utilizing one of 3 tax methods or elections: Section 179, 100% bonus depreciation, and the $2,500 de minimis expensing safe harbor election. These methods or elections apply to new or used assets purchased for your business. Example: If you buy a new track loader and finance it over 5 years with the bank, then you can write off the entire cost of the track loader in year 1 even though you only had the cash outlay of the down payment in year 1.
