Publication 587
taxmap/pubs/p587-006.htm#en_us_publink1000226391This section discusses the depreciation and section 179 deductions
you may be entitled to take for furniture and equipment you use in your home for
business or work as an employee. These deductions are available whether or not
you qualify to deduct expenses for the business use of your home.
This section explains the different rules for each of the following.
- Listed property.
- Property bought for business use.
- Personal property converted to business use.
taxmap/pubs/p587-006.htm#en_us_publink1000226392If you use certain types of property, called listed property,
in your home, special rules apply. Listed property includes computers and
related equipment and any property of a type generally used for entertainment,
recreation, and amusement (including photographic, phonographic, and video
recording equipment).
taxmap/pubs/p587-006.htm#en_us_publink1000226393Computers and related equipment used exclusively in a qualifying
office in your home are not listed property. If you qualify to deduct expenses
for the business use of your home (see
Qualifying for a Deduction, earlier) and you use your computer exclusively in your qualifying
office in the home, do not use the listed property rules discussed below.
Instead, follow the rules discussed under
Property Bought for Business Use, later.
taxmap/pubs/p587-006.htm#en_us_publink1000226394If you bought listed property and placed it in service during
the year, you must use it more than 50% for business (including work as an
employee) to claim a section 179 deduction or an accelerated depreciation
deduction.
If your business use of listed property is 50% or less, you cannot
take a section 179 deduction and you must depreciate the property using the
Alternative Depreciation System (ADS) (straight line method). For more
information on ADS, see Publication 946.
Listed property meets the more-than-50%-use test for any year
if its qualified business use is more than 50% of its total use. You must
allocate the use of any item of listed property used for more than one purpose
during the year among its various uses. You cannot use the percentage of
investment use as part of the percentage of qualified business use to meet the
more-than-50%-use test. However, you do use the combined total of business and
investment use to figure your depreciation deduction for the property.
taxmap/pubs/p587-006.htm#en_us_publink1000226395Sarah does not qualify to claim a deduction for the business
use of her home, but she uses her home computer 40% of the time for a business
she operates out of her home. She also uses the computer 50% of the time to
manage her investments. Sarah's home computer is listed property because it is
not used in a qualified office in her home. She does not use the computer more
than 50% for business, so she cannot elect a section 179 deduction. She can use
her combined business/investment use (90%) to figure her depreciation deduction
using ADS.
taxmap/pubs/p587-006.htm#en_us_publink1000226396If Sarah uses her computer 60% of the time for her business and
30% for managing her investments, her computer meets the more-than-50%-use test.
She can elect a section 179 deduction. She can use her combined
business/investment use (90%) to figure her depreciation deduction using the
General Depreciation System (GDS).
taxmap/pubs/p587-006.htm#en_us_publink1000226397If you use your own listed property (or listed property you rent)
in your work as an employee, the property is business-use property only if you
meet the following requirements.
- The use is for your employer's convenience.
- The use is required as a condition of your employment.
The use of property as a condition of your employment means that
it is necessary for you to properly perform your work. Whether the use of the
property is required for this purpose depends on all the facts and
circumstances. Your employer does not have to tell you specifically to use the
property. Nor is a statement by your employer to that effect sufficient.
taxmap/pubs/p587-006.htm#en_us_publink1000226398If, in a year after you place an item of listed property in service,
you fail to meet the more-than-50%-use test for that item of property, you may
be required to do the following.
- Figure depreciation, beginning with the year you no longer
use the property more than 50% for business, using the straight line method
(ADS).
- Figure any excess depreciation (include any section 179 deduction
on the property in figuring excess depreciation) and add it to:
- Your gross income, and
- The adjusted basis of your property.
For more information, see Publication 946.
taxmap/pubs/p587-006.htm#en_us_publink1000226399If you use listed property in your business, you must file Form
4562 to claim a depreciation or section 179 deduction. Begin with Part V,
Section A, of that form.
 | You cannot take any depreciation or section 179 deduction
for the use of listed property unless you can prove your business/investment use
with adequate records or sufficient evidence to support your own statements.
To meet the adequate records requirement, you must maintain an account book,
diary, log, statement of expense, trip sheet, or similar record or other
documentary evidence that is sufficient to establish business/investment use.
For more information on what records to keep, see Publication 946.

taxmap/pubs/p587-006.htm#en_us_publink1000226401If you bought certain property during 2010 to use in your business,
you can do any one of the following (subject to the limits discussed later).
- Elect a section 179 deduction for the full cost of the property.
- Depreciate the full cost of the property.
- Take part of the cost as a section 179 deduction and depreciate
the balance.
taxmap/pubs/p587-006.htm#en_us_publink1000226402You can claim the section 179 deduction for the cost of depreciable
tangible personal property bought for use in your trade or business. You can
choose how much (subject to the limit) of the cost you want to deduct under
section 179 and how much you want to depreciate. You can spread the section 179
deduction over several items of property in any way you choose as long as the
total does not exceed the maximum allowable. You cannot take a section 179
deduction for the basis of the business part of your home.
You elect the section 179 deduction by completing Part I of Form
4562.
taxmap/pubs/p587-006.htm#en_us_publink1000226403For more information on the section 179 deduction, qualifying
property, the dollar limit, and the business income limit, see Publication 946
and the Form 4562 Instructions.

You can take a special depreciation allowance to recover part of the cost of
certain qualified Gulf Opportunity Zone (GO Zone) property placed in service
during the tax year. The allowance applies for the first year you place the
property in service. For certain qualified property placed in service in 2010,
you can take an additional deduction of 50% of the property's depreciable basis
(after any section 179 deduction and before you figure regular depreciation).
For more information, see Publication 946. |
Use Parts II and III of Form 4562 to claim your deduction for
depreciation on property placed in service during the year. Do not include any
costs deducted in Part I (section 179 deduction).
Most business property normally used in a home office is either
5-year or 7-year property under MACRS.
- 5-year property includes computers and peripheral equipment,
typewriters, calculators, adding machines, and copiers.
- 7-year property includes office furniture and fixtures such
as desks, files, and safes.
Under MACRS, you generally use the half-year convention, which
allows you to deduct a half year of depreciation in the first year you use the
property in your business. If you place more than 40% of your depreciable
property in service during the last 3 months of your tax year, you must use the
mid-quarter convention instead of the half-year convention.
After you have determined the cost of the depreciable property
(minus any section 179 deduction and special depreciation allowance taken on the
property) and whether it is 5-year or 7-year property, use the table, shown
next, to figure your depreciation if the half-year convention applies.
Table 4. MACRS Percentage Table for 5- and 7-Year Property
Using Half-Year Convention
| Recovery Year | 5-Year Property | 7-Year Property |
|---|
| 1 | 20.00% | 14.29% |
| 2 | 32.00% | 24.49% |
| 3 | 19.20% | 17.49% |
| 4 | 11.52% | 12.49% |
| 5 | 11.52% | 8.93% |
| 6 | 5.76% | 8.92% |
| 7 | | 8.93% |
| 8 | | 4.46% |
See Publication 946 for a discussion of the mid-quarter convention
and for complete MACRS percentage tables.
taxmap/pubs/p587-006.htm#en_us_publink1000226407In June 2010, Donald Kent bought a desk and three chairs for
use in his office. His total bill for the furniture was $1,975. His taxable
business income for the year was $3,000 without any deduction for the office
furniture. Donald can elect to do one of the following.
- Take a section 179 deduction for the full cost of the office
furniture.
- Take part of the cost of the furniture as a section 179 deduction
and depreciate the balance.
- Depreciate the full cost of the office furniture.
The furniture is 7-year property under MACRS. Donald does not
take a section 179 deduction. He multiplies $1,975 by 14.29% (.1429) to get his
MACRS depreciation deduction of $282.23.
taxmap/pubs/p587-006.htm#en_us_publink1000226408If you use property in your home office that was used previously
for personal purposes, you cannot take a section 179 deduction for the property.
You also cannot take a special depreciation allowance for the property. You can
depreciate it, however. The method of depreciation you use depends on when you
first used the property for personal purposes.
If you began using the property for personal purposes after 1986
and change it to business use in 2010, depreciate the property under MACRS.
The basis for depreciation of property changed from personal
to business use is the lesser of the following.
- The adjusted basis of the property on the date of change.
- The fair market value of the property on the date of change.
If you began using the property for personal purposes after 1980
and before 1987 and change it to business use in 2010, you generally depreciate
the property under the accelerated cost recovery system (ACRS). However, if the
depreciation under ACRS is greater in the first year than the depreciation under
MACRS, you must depreciate it under MACRS. For information on ACRS, see
Publication 534, Depreciating Property Placed in Service Before 1987.
If you began using the property for personal purposes before
1981 and change it to business use in 2010, depreciate the property by the
straight line or declining balance method based on salvage value and useful
life.
