Publication 551
taxmap/pubs/p551-001.htm#en_us_publink1000256940Before figuring gain or loss on a sale, exchange, or other disposition
of property or figuring allowable depreciation, depletion, or amortization, you
must usually make certain adjustments to the basis of the property. The result
of these adjustments to the basis is the adjusted basis.
taxmap/pubs/p551-001.htm#en_us_publink1000256941Increase the basis of any property by all items properly added
to a capital account. These include the cost of any improvements having a useful
life of more than 1 year.
Rehabilitation expenses also increase basis. However, you must
subtract any rehabilitation credit allowed for these expenses before you add
them to your basis. If you have to recapture any of the credit, increase your
basis by the recaptured amount.
If you make additions or improvements to business property, keep
separate accounts for them. Also, you must depreciate the basis of each
according to the depreciation rules that would apply to the underlying property
if you had placed it in service at the same time you placed the addition or
improvement in service. For more information, see Publication 946.
The following items increase the basis of property.
- The cost of extending utility service lines to the property;
- Impact fees;
- Legal fees, such as the cost of defending and perfecting title;
- Legal fees for obtaining a decrease in an assessment levied
against property to pay for local improvements;
- Zoning costs; and
- The capitalized value of a redeemable ground rent.
taxmap/pubs/p551-001.htm#en_us_publink1000256942Increase the basis of property by assessments for items such
as paving roads and building ditches that increase the value of the property
assessed. Do not deduct them as taxes. However, you can deduct as taxes charges
for maintenance, repairs, or interest charges related to the improvements.
taxmap/pubs/p551-001.htm#en_us_publink1000256943Your city changes the street in front of your store into an enclosed
pedestrian mall and assesses you and other affected landowners for the cost of
the conversion. Add the assessment to your property's basis. In this example,
the assessment is a depreciable asset.
taxmap/pubs/p551-001.htm#en_us_publink1000256944Do not add to your basis costs you can deduct as current expenses.
For example, amounts paid for incidental repairs or maintenance that are
deductible as business expenses cannot be added to basis. However, you can
choose either to deduct or to capitalize certain other costs. If you capitalize
these costs, include them in your basis. If you deduct them, do not include them
in your basis. See
Uniform Capitalization Rules
earlier.
The costs you can choose to deduct or to capitalize include the
following.
- Carrying charges, such as interest and taxes, that you pay
to own property, except carrying charges that must be capitalized under the
uniform capitalization rules;
- Research and experimentation costs;
- Intangible drilling and development costs for oil, gas, and
geothermal wells;
- Exploration costs for new mineral deposits;
- Mining development costs for a new mineral deposit;
- Costs of establishing, maintaining, or increasing the circulation
of a newspaper or other periodical; and
- Costs of removing architectural and transportation barriers
to people with disabilities and the elderly. If you claim the disabled access
credit, you must reduce the amount you deduct or capitalize by the amount of the
credit.
For more information about deducting or capitalizing costs, see
chapter 7 in Publication 535.

taxmap/pubs/p551-001.htm#en_us_publink1000256947If you have a casualty or theft loss, decrease the basis in your
property by any insurance or other reimbursement and by any deductible loss not
covered by insurance.
You must increase your basis in the property by the amount you
spend on repairs that substantially prolong the life of the property, increase
its value, or adapt it to a different use. To make this determination, compare
the repaired property to the property before the casualty. For more information
on casualty and theft losses, see Publication 547, Casualties, Disasters, and
Thefts.
taxmap/pubs/p551-001.htm#en_us_publink1000256948The amount you receive for granting an easement is generally
considered to be a sale of an interest in real property. It reduces the basis of
the affected part of the property. If the amount received is more than the basis
of the part of the property affected by the easement, reduce your basis in that
part to zero and treat the excess as a recognized gain.
taxmap/pubs/p551-001.htm#en_us_publink1000256949Unless you elect not to claim the qualified plug-in electric
vehicle credit, the alternative motor vehicle credit, or the qualified plug-in
electric drive motor vehicle credit, you may have to reduce the basis of each
qualified vehicle by certain amounts reported. For more information, see Form
8834, Qualified Plug-in Electric and Electric Vehicle Credit; Form 8910,
Alternative Motor Vehicle Credit; Form 8936, Qualified Plug-in Electric Drive
Motor Vehicle Credit;and the related instructions.
taxmap/pubs/p551-001.htm#en_us_publink1000256950Decrease the basis in your car by the gas-guzzler (fuel economy)
tax if you begin using the car within 1 year of the date of its first sale for
ultimate use. This rule also applies to someone who later buys the car and
begins using it not more than 1 year after the original sale for ultimate use.
If the car is imported, the one-year period begins on the date of entry or
withdrawal of the car from the warehouse if that date is later than the date of
the first sale for ultimate use.
taxmap/pubs/p551-001.htm#en_us_publink1000256951If you take the section 179 deduction for all or part of the
cost of qualifying business property, decrease the basis of the property by the
deduction. For more information about the section 179 deduction, see Publication
946.
taxmap/pubs/p551-001.htm#en_us_publink1000256953You can exclude from gross income any subsidy you received from
a public utility company for the purchase or installation of any energy
conservation measure for a dwelling unit. Reduce the basis of the property for
which you received the subsidy by the excluded amount. For more information on
this subsidy, see Publication 525.
taxmap/pubs/p551-001.htm#en_us_publink1000256954Decrease the basis of property by the depreciation you deducted,
or could have deducted, on your tax returns under the method of depreciation you
chose. If you took less depreciation than you could have under the method
chosen, decrease the basis by the amount you could have taken under that method.
If you did not take a depreciation deduction, reduce the basis by the full
amount of the depreciation you could have taken.
Unless a timely election is made not to deduct the special depreciation
allowance for property placed in service after September 10, 2001, decrease the
property's basis by the special depreciation allowance you deducted or could
have deducted.
If you deducted more depreciation than you should have, decrease
your basis by the amount equal to the depreciation you should have deducted plus
the part of the excess depreciation you deducted that actually reduced your tax
liability for the year.
In decreasing your basis for depreciation, take into account
the amount deducted on your tax returns as depreciation and any depreciation
capitalized under the uniform capitalization rules.
For information on figuring depreciation, see Publication 946.
If you are claiming depreciation on a business vehicle, see Publication
463. If the car is not used more than 50% for business during the tax year, you
may have to recapture excess depreciation. Include the excess depreciation in
your gross income and add it to your basis in the property. For information on
the computation of excess depreciation, see chapter 4 in Publication 463.
taxmap/pubs/p551-001.htm#en_us_publink1000256955If a debt you owe is canceled or forgiven, other than as a gift
or bequest, you generally must include the canceled amount in your gross income
for tax purposes. A debt includes any indebtedness for which you are liable or
which attaches to property you hold.
You can exclude canceled debt from income in the following situations.
- Debt canceled in a bankruptcy case or when you are insolvent,
- Qualified farm debt, and
- Qualified real property business debt (provided you are not
a C corporation).
If you exclude from income canceled debt under situation (1)
or (2), you may have to reduce the basis of your depreciable and nondepreciable
property. However, in situation (3), you must reduce the basis of your
depreciable property by the excluded amount.
For more information about canceled debt in a bankruptcy case
or during insolvency, see Publication 908, Bankruptcy Tax Guide. For more
information about canceled debt that is qualified farm debt, see chapter 3 in
Publication 225. For more information about qualified real property business
debt, see chapter 5 in Publication 334, Tax Guide for Small Business.
taxmap/pubs/p551-001.htm#en_us_publink1000256956If you postponed gain from the sale of your main home before
May 7, 1997, you must reduce the basis of your new home by the postponed gain.
For more information on the rules for the sale of a home, see Publication 523.
taxmap/pubs/p551-001.htm#en_us_publink1000256957If you claim an adoption credit for the cost of improvements
you added to the basis of your home, decrease the basis of your home by the
credit allowed. This also applies to amounts you received under an employer's
adoption assistance program and excluded from income. For more information Form
8839, Qualified Adoption Expenses.
taxmap/pubs/p551-001.htm#en_us_publink1000256958If you are an employer, you can claim the employer-provided child
care credit on amounts you paid or incurred to acquire, construct, rehabilitate,
or expand property used as part of your qualified child care facility. You must
reduce your basis in that property by the credit claimed. For more information,
see Form 8882, Credit for Employer-Provided Child Care Facilities and Services.
taxmap/pubs/p551-001.htm#en_us_publink1000256959In January 2005, you paid $80,000 for real property to be used
as a factory. You also paid commissions of $2,000 and title search and legal
fees of $600. You allocated the total cost of $82,600 between the land and the
building—$10,325 for the land and $72,275 for the building. Immediately
you spent $20,000 in remodeling the building before you placed it in service.
You were allowed depreciation of $14,526 for the years 2005 through 2009. In
2008 you had a $5,000 casualty loss from a that was not covered by insurance on
the building. You claimed a deduction for this loss. You spent $5,500 to repair
the damages and extend the useful life of the building. The adjusted basis of
the building on January 1, 2010, is figured as follows:
| Original cost of building including fees and commissions | $72,275 |
| Adjustments to basis: | | |
| Add: | | | |
| | Improvements | 20,000 |
| | Repair of damages | 5,500 |
| | | | $97,775 |
| Subtract: | | |
| | Depreciation | $14,526 | |
| | Deducted casualty loss | 5,000 | 19,526 |
| Adjusted basis on January 1, 2010 | $78,249 |
The basis of the land, $10,325, remains unchanged. It is not
affected by any of the above adjustments.
