MACRS provides three depreciation methods under GDS and one depreciation
method under ADS.
- The 200% declining balance method over a GDS recovery period.
- The 150% declining balance method over a GDS recovery period.
- The straight line method over a GDS recovery period.
- The straight line method over an ADS recovery period.
 | For property placed in service before 1999, you could have
elected the 150% declining balance method using the ADS recovery periods for
certain property classes. If you made this election, continue to use the same
method and recovery period for that property.

Table 4-1
lists the types of property you can depreciate under each method.
It also gives a brief explanation of the method, including any benefits that may
apply.
taxmap/pubs/p946-025.htm#en_us_publink1000107545If you place personal property in service in a farming business
after 1988, you generally must depreciate it under GDS using the 150% declining
balance method unless you are a farmer who must depreciate the property under
ADS using the straight line method or you elect to depreciate the property under
GDS or ADS using the straight line method. You can depreciate real property
using the straight line method under either GDS or ADS.
taxmap/pubs/p946-025.htm#en_us_publink1000107546Depreciate trees and vines bearing fruit or nuts under GDS using
the straight line method over a recovery period of 10 years.
taxmap/pubs/p946-025.htm#en_us_publink1000107547If you elect not to apply the uniform capitalization rules to
any plant produced in your farming business, you must use ADS. You must use ADS
for all property you place in service in any year the election is in effect. See
the regulations under section 263A of the Internal Revenue Code for information
on the uniform capitalization rules that apply to farm property.
taxmap/pubs/p946-025.htm#en_us_publink1000107548As shown in
Table 4-1, you can elect a different method for depreciation for certain
types of property. You must make the election by the due date of the return
(including extensions) for the year you placed the property in service. However,
if you timely filed your return for the year without making the election, you
still can make the election by filing an amended return within 6 months of the
due date of the return (excluding extensions). Attach the election to the
amended return and write "Filed pursuant to section 301.9100-2" on the election
statement. File the amended return at the same address you filed the original
return. Once you make the election, you cannot change it.
 | If you elect to use a different method for one item in a
property class, you must apply the same method to all property in that class
placed in service during the year of the election. However, you can make the
election on a property-by-property basis for nonresidential real and residential
rental property.

taxmap/pubs/p946-025.htm#en_us_publink1000107550Instead of using the 200% declining balance method over the GDS
recovery period for nonfarm property in the 3-, 5-, 7-, and 10-year property
classes, you can elect to use the 150% declining balance method. Make the
election by entering "150 DB" under column (f) in Part III of Form 4562.
taxmap/pubs/p946-025.htm#en_us_publink1000107551Instead of using either the 200% or 150% declining balance methods
over the GDS recovery period, you can elect to use the straight line method over
the GDS recovery period. Make the election by entering
"S/L" under column (f) in Part III of Form 4562.
taxmap/pubs/p946-025.htm#en_us_publink1000107552As explained earlier under
Which Depreciation System (GDS or ADS) Applies, you can elect to use ADS even though your property may come
under GDS. ADS uses the straight line method of depreciation over fixed ADS
recovery periods. Most ADS recovery periods are listed in Appendix B, or see the
table under
Recovery Periods Under ADS, earlier.
Make the election by completing line 20 in Part III of Form 4562.
taxmap/pubs/p946-025.htm#en_us_publink1000107553Instead of using the 150% declining balance method over a GDS
recovery period for property you use in a farming business (other than real
property), you can elect to depreciate it using either of the following methods.
- The straight line method over a GDS recovery period.
- The straight line method over an ADS recovery period.
