Federal depreciation for newly purchased business assets is governed by the rules in the Internal Revenue Code (IRC), Treasury Regulations, and IRS guidance. The key principles for when depreciation begins and ends are as follows:
1. When Does Depreciation Begin?
Depreciation begins when the asset is "placed in service" for use in your trade or business or for the production of income. "Placed in service" means the date the property is ready and available for a specific use, whether or not it is actually being used at that moment. The asset does not need to be in actual use, but it must be ready and available for its intended business purpose.
- For example, if you purchase a machine and it is delivered and installed in December, but you do not actually use it until the following year, depreciation begins in December if the machine was ready and available for use at that time.
- If the asset requires assembly or installation, it is not considered placed in service until that process is complete and the asset is ready for its intended use.
- For real property, such as a building, it is placed in service when it is ready and available for its intended function (e.g., a rental property is ready for tenants, even if not yet rented).
Special Rules: For assets converted from personal to business use, depreciation begins on the date of conversion.- For certain assets, such as fruit or nut trees, depreciation begins when the asset reaches the income-producing stage (e.g., when the tree bears fruit in commercially viable quantities).
2. When Does Depreciation End?
Depreciation ends when you have fully recovered your cost or other basis in the property (i.e., when the total of your depreciation deductions equals your cost or basis), or when you retire the property from service, whichever occurs first.
Retirement from service occurs when the property is permanently withdrawn from use in your trade or business or from use in the production of income. This can happen due to:
- Sale or exchange of the property
- Conversion to personal use
- Abandonment
- Destruction (e.g., casualty loss)
- Transfer to a supplies or scrap account
If the property is temporarily idle (not in use), you continue to claim depreciation as long as it is still held for use in your business or for the production of income. For example, if a machine is temporarily not used due to lack of demand, but is still available for use, depreciation continues.
3. Summary Table:
In summary: Federal depreciation begins when the asset is placed in service (ready and available for its intended business use) and ends when the asset is fully depreciated or is permanently withdrawn from business use (by sale, abandonment, destruction, or conversion to personal use).
