- Placed in service
You begin to depreciate your property when you place it in service for use in your trade or business or for the production of income. You stop depreciating property either when you have fully recovered your cost or other basis or when you retire it from service, whichever happens first. taxmap/pubs/p946-003.htm#en_us_publink1000107328
You place property in service when it is ready and available for a specific use, whether in a business activity, an income-producing activity, a tax-exempt activity, or a personal activity. Even if you are not using the property, it is in service when it is ready and available for its specific use. taxmap/pubs/p946-003.htm#en_us_publink1000107329
Donald Steep bought a machine for his business. The machine was delivered last year. However, it was not installed and operational until this year. It is considered placed in service this year. If the machine had been ready and available for use when it was delivered, it would be considered placed in service last year even if it was not actually used until this year.taxmap/pubs/p946-003.htm#en_us_publink1000107330

If you place property in service in a personal activity, you cannot claim depreciation. However, if you change the property's use to use in a business or income-producing activity, then you can begin to depreciate it at the time of the change. You place the property in service on the date of the change.taxmap/pubs/p946-003.htm#en_us_publink1000107333
You bought a home and used it as your personal home several years before you converted it to rental property. Although its specific use was personal and no depreciation was allowable, you placed the home in service when you began using it as your home. You can begin to claim depreciation in the year you converted it to rental property because its use changed to an income-producing use at that time. taxmap/pubs/p946-003.htm#en_us_publink1000107334
Continue to claim a deduction for depreciation on property used in your business or for the production of income even if it is temporarily idle (not in use). For example, if you stop using a machine because there is a temporary lack of a market for a product made with that machine, continue to deduct depreciation on the machine. taxmap/pubs/p946-003.htm#en_us_publink1000107335
You stop depreciating property when you have fully recovered your cost or other basis. You recover your basis when your section 179 and allowed or allowable depreciation deductions equal your cost or investment in the property. See What Is the Basis of Your Depreciable Property, later.taxmap/pubs/p946-003.htm#en_us_publink1000107336
You stop depreciating property when you retire it from service, even if you have not fully recovered its cost or other basis. You retire property from service when you permanently withdraw it from use in a trade or business or from use in the production of income because of any of the following events.
- You sell or exchange the property.
- You convert the property to personal use.
- You abandon the property.
- You transfer the property to a supplies or scrap account.
- The property is destroyed.
