You've done it. You've finally met your goal of securing a consistent revenue (say X amount) for your company every year for the foreseeable future. You're in the rubber-band business. And surprisingly, the revenue stream is quite predictable. Once a retailer buys from you, it's for life.
However, it's also time you replace your rubber-mixing vats. You've got hundreds of them. So you know it's going to be costly... But it's OK since you plan on using the life out of these vats till they fall apart. And at least that will be a nice tax write-off!
Filling out the tax sheets, you realize you've got 2 options: You can "depreciate" your new vats according to the Straight-Line method or the MACRS method. Like any responsible business-owner, you want to minimize your taxes and ensure the long-term health of your business. Which depreciation method should you choose?
