>When companies buy expensive stuff, for accounting purposes they pretend they haven’t spent the money; instead they “depreciate” it over a few years

I thought there was a US IRS Law that was changed sometime in the past 10/15 years that made companies depreciate computer hardware in 1 year. Am I misremembering ?

I thought that law was the reason why many companies increased the life time of employee Laptops from 3 to 5 years.
