This chapter primarily explains business income and how to account for it on your tax return, what items are not considered
income, and gives guidelines for selected occupations.
If there is a connection between any income you receive and your business, the income is business income. A connection exists
if it is clear that the payment of income would not have been made if you did not have the business.
You can have business income even if you are not involved in the activity on a regular full-time basis. Income from work you
do on the side in addition to your regular job can be business income.
You report most business income, such as income from selling your products or services, on Schedule C or C-EZ. But you report
the income from the sale of business assets, such as land and office buildings, on other forms instead of Schedule C or C-EZ.
For information on selling business assets, see chapter 3.
Nonemployee compensation. Business income includes amounts you received in your business that were properly shown on Forms 1099-MISC. This includes
amounts reported as nonemployee compensation in box 7 of the form. You can find more information in the instructions on the
back of the Form 1099-MISC you received.
You must report on your tax return all income you receive from your business unless it is excluded by law. In most cases,
your business income will be in the form of cash, checks, and credit card charges. But business income can be in other forms,
such as property or services. These and other types of income are explained next.
If you are a U.S. citizen who has business income from sources outside the United States (foreign income), you must report
that income on your tax return unless it is exempt from tax under U.S. law. If you live outside the United States, you may
be able to exclude part or all of your foreign-source business income. For details, see Publication 54, Tax Guide for U.S.
Citizens and Resident Aliens Abroad.
Bartering for Property or Services
Bartering is an exchange of property or services. You must include in your gross receipts, at the time received, the fair
market value of property or services you receive in exchange for something else. If you exchange services with another person
and you both have agreed ahead of time on the value of the services, that value will be accepted as the fair market value
unless the value can be shown to be otherwise.
You are a self-employed lawyer. You perform legal services for a client, a small corporation. In payment for your services,
you receive shares of stock in the corporation. You must include the fair market value of the shares in income.
You are an artist and create a work of art to compensate your landlord for the rent-free use of your apartment. You must include
the fair rental value of the apartment in your gross receipts. Your landlord must include the fair market value of the work
of art in his or her rental income.
You are a self-employed accountant. Both you and a house painter are members of a barter club, an organization that each year
gives its members a directory of members and the services each member provides. Members get in touch with other members directly
and bargain for the value of the services to be performed.
In return for accounting services you provided for the house painter's business, the house painter painted your home. You
must include in gross receipts the fair market value of the services you received from the house painter. The house painter
must include the fair market value of your accounting services in his or her gross receipts.
You are a member of a barter club that uses credit units to credit or debit members' accounts for goods or services provided
or received. As soon as units are credited to your account, you can use them to buy goods or services or sell or transfer
the units to other members.
You must include the value of credit units you received in your gross receipts for the tax year in which the units are credited
to your account.
The dollar value of units received for services by an employee of the club, who can use the units in the same manner as other
members, must be included in the employee's gross income for the tax year in which received. It is wages subject to social
security and Medicare taxes (FICA), federal unemployment taxes (FUTA), and income tax withholding. See Publication 15 (Circular
E), Employer's Tax Guide.
You operate a plumbing business and use the cash method of accounting. You join a barter club and agree to provide plumbing
services to any member for a specified number of hours. Each member has access to a directory that lists the members of the
club and the services available.
Members contact each other directly and request services to be performed. You are not required to provide services unless
requested by another member, but you can use as many of the offered services as you wish without paying a fee.
You must include the fair market value of any services you receive from club members in your gross receipts when you receive
them even if you have not provided any services to club members.
If you are involved in a bartering transaction, you may have to file either of the following forms.
Form 1099-B, Proceeds From Broker and Barter Exchange Transactions.
Form 1099-MISC, Miscellaneous Income.
For information about these forms, see the General Instructions for Certain Information Returns.
If you are a real estate dealer who receives income from renting real property or an owner of a hotel, motel, etc., who provides
services (maid services, etc.) for guests, report the rental income and expenses on Schedule C or C-EZ. If you are not a real
estate dealer or the kind of owner described in the preceding sentence, report the rental income and expenses on Schedule
E. For more information, see Publication 527, Residential Rental Property (Including Rental of Vacation Homes).
Real estate dealer.
You are a real estate dealer if you are engaged in the business of selling real estate to customers with the purpose
of making a profit from those sales. Rent you receive from real estate held for sale to customers is subject to SE tax. However,
rent you receive from real estate held for speculation or investment is not subject to SE tax.
Trailer park owner.
Rental income from a trailer park is subject to SE tax if you are a self-employed trailer park owner who provides
trailer lots and facilities and substantial services for the convenience of your tenants.
You generally are considered to provide substantial services for tenants if they are primarily for the tenants' convenience
and normally are not provided to maintain the lots in a condition for occupancy. Services are substantial if the compensation
for the services makes up a material part of the tenants' rental payments.
Examples of services that are not normally provided for the tenants' convenience include supervising and maintaining
a recreational hall provided by the park, distributing a monthly newsletter to tenants, operating a laundry facility, and
helping tenants buy or sell their trailers.
Examples of services that are normally provided to maintain the lots in a condition for tenant occupancy include city
sewerage, electrical connections, and roadways.
Hotels, boarding houses, and apartments.
Rental income you receive for the use or occupancy of hotels, boarding houses, or apartment houses is subject to SE
tax if you provide services for the occupants.
Generally, you are considered to provide services for the occupants if the services are primarily for their convenience
and are not services normally provided with the rental of rooms for occupancy only. An example of a service that is not normally
provided for the convenience of the occupants is maid service. However, providing heat and light, cleaning stairways and lobbies,
and collecting trash are services normally provided for the occupants' convenience.
Advance payments received under a lease that does not put any restriction on their use or enjoyment are income in
the year you receive them. This is true no matter what accounting method or period you use.
A bonus you receive from a lessee for granting a lease is an addition to the rent. Include it in your gross receipts
in the year received.
Lease cancellation payments.
Report payments you receive from your lessee for canceling a lease in your gross receipts in the year received.
Payments to third parties.
If your lessee makes payments to someone else under an agreement to pay your debts or obligations, include the payments
in your gross receipts when the lessee makes the payments. A common example of this kind of income is a lessee's payment of
your property taxes on leased real property.
Payments you receive in settlement of a lessee's obligation to restore the leased property to its original condition
are income in the amount that the payments exceed the adjusted basis of the leasehold improvements destroyed, damaged, removed,
or disconnected by the lessee.
If you are in the business of renting personal property (equipment, vehicles, formal wear, etc.), include the rental amount
you receive in your gross receipts on Schedule C or C-EZ. Prepaid rent and other payments described in the preceding Real Estate Rents discussion can also be received for renting personal property. If you receive any of those payments, include them in your
gross receipts as explained in that discussion.
Interest and Dividend Income
Interest and dividends may be considered business income.
Interest received on notes receivable that you have accepted in the ordinary course of business is business income.
Interest received on loans is business income if you are in the business of lending money.
If a loan payable to you becomes uncollectible during the tax year and you use an accrual method of accounting, you
must include in gross income interest accrued up to the time the loan became uncollectible. If the accrued interest later
becomes uncollectible, you may be able to take a bad debt deduction. See
in chapter 8.
If little or no interest is charged on an installment sale, you may have to treat a part of each payment as unstated
interest. See Unstated Interest and Original Issue Discount (OID)
in Publication 537, Installment Sales.
Generally, dividends are business income to dealers in securities. For most sole proprietors and statutory employees,
however, dividends are nonbusiness income. If you hold stock as a personal investment separately from your business activity,
the dividends from the stock are nonbusiness income.
If you receive dividends from business insurance premiums you deducted in an earlier year, you must report all or
part of the dividend as business income on your return. To find out how much you have to report, see
Recovery of items previously deducted
under Other Income,
The following explains the general rule for including canceled debt in income and the exceptions to the general rule.
Generally, if your debt is canceled or forgiven, other than as a gift or bequest to you, you must include the canceled amount
in your gross income for tax purposes. Report the canceled amount on line 6 of Schedule C if you incurred the debt in your
business. If the debt is a nonbusiness debt, report the canceled amount on line 21 of Form 1040.
The following discussion covers some exceptions to the general rule for canceled debt.
Price reduced after purchase.
If you owe a debt to the seller for property you bought and the seller reduces the amount you owe, you generally do
not have income from the reduction. Unless you are bankrupt or insolvent, treat the amount of the reduction as a purchase
price adjustment and reduce your basis in the property.
You do not realize income from a canceled debt to the extent the payment of the debt would have led to a deduction.
You get accounting services for your business on credit. Later, you have trouble paying your business debts, but you are not
bankrupt or insolvent. Your accountant forgives part of the amount you owe for the accounting services. How you treat the
canceled debt depends on your method of accounting.
Cash method — You do not include the canceled debt in income because payment of the debt would have been deductible as a business
Accrual method — You include the canceled debt in income because the expense was deductible when you incurred the debt.
For information on the cash and accrual methods of accounting, see chapter 2
Do not include canceled debt in income in the following situations. However, you may be required to file Form 982, Reduction of Tax Attributes Due to Discharge of Indebtedness. For more information, see Form 982.
The cancellation takes place in a bankruptcy case under title 11 of the U.S. Code (relating to bankruptcy). See Publication
908, Bankruptcy Tax Guide.
The cancellation takes place when you are insolvent. You can exclude the canceled debt to the extent you are insolvent. See
The canceled debt is a qualified farm debt owed to a qualified person. See chapter 3 in Publication 225, Farmer's Tax Guide.
The canceled debt is a qualified real property business debt. This situation is explained later.
The canceled debt is qualified principal residence indebtedness which is discharged after 2006. See Form 982.
If a canceled debt is excluded from income because it takes place in a bankruptcy case, the exclusions in situations 2 through
5 do not apply. If it takes place when you are insolvent, the exclusions in situations 3 and 4 do not apply to the extent
you are insolvent.
For purposes of this discussion, debt includes any debt for which you are liable or which attaches to property you
Qualified real property business debt.
You can elect to exclude (up to certain limits) the cancellation of qualified real property business debt. If you
make the election, you must reduce the basis of your depreciable real property by the amount excluded. Make this reduction
at the beginning of your tax year following the tax year in which the cancellation occurs. However, if you dispose of the
property before that time, you must reduce its basis immediately before the disposition.
Cancellation of qualified real property business debt.
Qualified real property business debt is debt (other than qualified farm debt) that meets all the following conditions.
It was incurred or assumed in connection with real property used in a trade or business.
It was secured by such real property.
It was incurred or assumed at either of the following times.
Before January 1, 1993.
After December 31, 1992, if incurred or assumed to acquire, construct, or substantially improve the real property.
It is debt to which you choose to apply these rules.
Qualified real property business debt includes refinancing of debt described in (3) earlier, but only to the extent
it does not exceed the debt being refinanced.
If you are the owner of a disregarded entity (for example, a single-member LLC) see Qualified Real Property Business Indebtedness
in chapter 1 of Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments, to see if you qualify for
You cannot exclude more than either of the following amounts.
The excess (if any) of:
The outstanding principal of qualified real property business debt (immediately before the cancellation), over
The fair market value (immediately before the cancellation) of the business real property that is security for the debt, reduced
by the outstanding principal amount of any other qualified real property business debt secured by this property immediately
before the cancellation.
The total adjusted bases of depreciable real property held by you immediately before the cancellation. These adjusted bases
are determined after any basis reduction due to a cancellation in bankruptcy, insolvency, or of qualified farm debt. Do not
take into account depreciable real property acquired in contemplation of the cancellation.
To make this election, complete Form 982 and attach it to your income tax return for the tax year in which the cancellation
occurs. You must file your return by the due date (including extensions). If you timely filed your return for the year without
making the election, you can still make the election by filing an amended return within 6 months of the due date of the return
(excluding extensions). For more information, see When To File
in the form instructions.
The following discussion explains how to treat other types of business income you may receive.
Restricted property is property that has certain restrictions that affect its value. If you receive restricted stock
or other property for services performed, the fair market value of the property in excess of your cost is included in your
income on Schedule C or C-EZ when the restriction is lifted. However, you can choose to be taxed in the year you receive the
property. For more information on including restricted property in income, see Publication 525, Taxable and Nontaxable Income.
Gains and losses.
Do not report on Schedule C or C-EZ a gain or loss from the disposition of property that is neither stock in trade
nor held primarily for sale to customers. Instead, you must report these gains and losses on other forms. For more information,
see chapter 3
Report promissory notes and other evidences of debt issued to you in a sale or exchange of property that is stock
in trade or held primarily for sale to customers on Schedule C or C-EZ. In general, you report them at their stated principal
amount (minus any unstated interest) when you receive them.
Lost income payments.
If you reduce or stop your business activities, report on Schedule C or C-EZ any payment you receive for the lost
income of your business from insurance or other sources. Report it on Schedule C or C-EZ even if your business is inactive
when you receive the payment.
You must include in gross income compensation you receive during the tax year as a result of any of the following
injuries connected with your business.
You may be entitled to a deduction against the income if it compensates you for actual economic injury. Your deduction
is the smaller of the following amounts.
You must also include punitive damages in income.
If you receive any kickbacks, include them in your income on Schedule C or C-EZ. However, do not include them if
you properly treat them as a reduction of a related expense item, a capital expenditure, or cost of goods sold.
Recovery of items previously deducted.
If you recover a bad debt or any other item deducted in a previous year, include the recovery in income on Schedule
C or C-EZ. However, if all or part of the deduction in earlier years did not reduce your tax, you can exclude the part that
did not reduce your tax. If you exclude part of the recovery from income, you must include with your return a computation
showing how you figured the exclusion.
Joe Smith, a sole proprietor, had gross income of $8,000, a bad debt deduction of $300, and other allowable deductions of
$7,700. He also had 2 personal exemptions for a total of $7,900. He would not pay income tax even if he did not deduct the
bad debt. Therefore, he will not report as income any part of the $300 he may recover in any future year.
Exception for depreciation.
This rule does not apply to depreciation. You recover depreciation using the rules explained next.
Recapture of depreciation.
In the following situations, you have to recapture the depreciation deduction. This means you include in income part
or all of the depreciation you deducted in previous years.
If your business use of listed property (explained in chapter 8 under
) falls to 50% or less in a tax year after the tax year you placed the property in service, you may have to recapture part
of the depreciation deduction. You do this by including in income on Schedule C part of the depreciation you deducted in previous
years. Use Part IV of
, Sales of Business Property, to figure the amount to include on Schedule C. For more information, see What is the Business-Use Requirement?
in chapter 5 of Publication 946, How To Depreciate Property. That chapter explains how to determine whether property is used
more than 50% in your business.
Section 179 property.
If you take a section 179 deduction (explained in chapter 8 under
) for an asset and before the end of the asset's recovery period the percentage of business use drops to 50% or less, you
must recapture part of the section 179 deduction. You do this by including in income on Schedule C part of the deduction you
took. Use Part IV of Form 4797 to figure the amount to include on Schedule C. See chapter 2 in Publication 946 to find out
when you recapture the deduction.
Sale or exchange of depreciable property.
If you sell or exchange depreciable property at a gain, you may have to treat all or part of the gain due to depreciation
as ordinary income. You figure the income due to depreciation recapture in Part III of Form 4797. For more information, see
chapter 4 in Publication 544, Sales and Other Dispositions of Assets.
Items That Are Not Income
In some cases the property or money you receive is not income.
Increases in value of your property are not income until you realize the increases through a sale or other taxable
Consignments of merchandise to others to sell for you are not sales. The title of merchandise remains with you, the
consignor, even after the consignee possesses the merchandise. Therefore, if you ship goods on consignment, you have no profit
or loss until the consignee sells the merchandise. Merchandise you have shipped out on consignment is included in your inventory
until it is sold.
Do not include merchandise you receive on consignment in your inventory. Include your profit or commission on merchandise
consigned to you in your income when you sell the merchandise or when you receive your profit or commission, depending upon
the method of accounting you use.
If you enter into a lease after August 5, 1997, you can exclude from income the construction allowance you receive
(in cash or as a rent reduction) from your landlord if you receive it under both the following conditions.
Amount you can exclude.
You can exclude the construction allowance to the extent it does not exceed the amount you spent for construction
A short-term lease is a lease (or other agreement for occupancy or use) of retail space for 15 years or less. The
following rules apply in determining whether the lease is for 15 years or less.
Take into account options to renew when figuring whether the lease is for 15 years or less. But do not take into account any
option to renew at fair market value determined at the time of renewal.
Two or more successive leases that are part of the same transaction (or a series of related transactions) for the same or
substantially similar retail space are treated as one lease.
Retail space is real property leased, occupied, or otherwise used by you as a tenant in your business of selling
tangible personal property or services to the general public.
Qualified long-term real property.
Qualified long-term real property is nonresidential real property that is part of, or otherwise present at, your
retail space and that reverts to the landlord when the lease ends.
Exchange of like-kind property.
If you exchange your business property or property you hold for investment solely for property of a like kind to
be used in your business or to be held for investment, no gain or loss is recognized. This means that the gain is not taxable
and the loss is not deductible. A common type of nontaxable exchange is the trade-in of a business automobile for another
business automobile. For more information, see Form 8824.
If a tenant erects buildings or makes improvements to your property, the increase in the value of the property due
to the improvements is not income to you. However, if the facts indicate that the improvements are a payment of rent to you,
then the increase in value would be income.
Money borrowed through a bona fide loan is not income.
State and local sales taxes imposed on the buyer, which you were required to collect and pay over to state or local
governments, are not income.
Guidelines for Selected Occupations
This section provides information to determine whether your earnings should be reported on Schedule C (Form 1040) or C-EZ

Delivering or distributing newspapers or shopping news (including any services directly related to that trade or business).
Substantially all your pay (whether paid in cash or not) for services described above is directly related to sales or other
output (including performance of services) rather than to the number of hours worked.
Your services are performed under a written contract between you and the person for whom you perform the services, and the
contract provides that you will not be treated as an employee for federal tax purposes.
Executor or administrator.

your service agreement or the extent to which those policies remain in force for some period after your service agreement
ended, or both.
The amount of the payment did not depend to any extent on length of service or overall earnings from services performed for
the company (regardless of whether eligibility for the payments depended on length of service).
Insurance agent, retired.
Income paid by an insurance company to a retired self-employed insurance agent based on a percentage of commissions
received before retirement is reported on Schedule C or C-EZ. Also, renewal commissions and deferred commissions for sales
made before retirement are generally reported on Schedule C or C-EZ.
However, renewal commissions paid to the survivor of an insurance agent are not reported on Schedule C or C-EZ.
Newspaper carrier or distributor.
You are a direct seller and your earnings are reported on Schedule C or C-EZ if all the following conditions apply.
You are in the business of delivering or distributing newspapers or shopping news (including directly related services such
as soliciting customers and collecting receipts).
Substantially all your pay for these services directly relates to your sales or other output rather than to the number of
hours you work.
You perform the services under a written contract that says you will not be treated as an employee for federal tax purposes.
This rule applies whether or not you hire others to help you make deliveries. It also applies whether you buy the

Public officials generally do not report what they earn for serving in public office on Schedule C or C-EZ. This
rule applies to payments received by an elected tax collector from state funds on the basis of a fixed percentage of the taxes
collected. Public office includes any elective or appointive office of the United States or its possessions, the District
of Columbia, a state or its political subdivisions, or a wholly owned instrumentality of any of these.

550, Investment Income and Expenses.
Accounting for Your Income
Accounting for your income for income tax purposes differs at times from accounting for financial purposes. This section discusses
some of the more common differences that may affect business transactions.
Figure your business income on the basis of a tax year and according to your regular method of accounting (see chapter 2). If the sale of a product is an income-producing factor in your business, you usually have to use inventories to clearly
show your income. Dealers in real estate are not allowed to use inventories. For more information on inventories, see chapter 2.
Income paid to a third party.
All income you earn is taxable to you. You cannot avoid tax by having the income paid to a third party.
You rent out your property and the rental agreement directs the lessee to pay the rent to your son. The amount paid to your
son is gross income to you.
These are amounts the seller permits you to deduct from the invoice price for prompt payment. For income tax purposes,
you can use either of the following two methods to account for cash discounts.
You must use the chosen method every year for all your purchase discounts.
If you use the second method, the credit balance in the account at the end of your tax year is business income. Under
this method, you do not reduce the cost of goods sold by the cash discounts you received. When valuing your closing inventory,
you cannot reduce the invoice price of merchandise on hand at the close of the tax year by the average or estimated discounts
received on the merchandise.
These are reductions from list or catalog prices and usually are not written into the invoice or charged to the customer.
Do not enter these discounts on your books of account. Instead, use only the net amount as the cost of the merchandise purchased.
For more information, see
in chapter 6.
Payment placed in escrow.
If the buyer of your property places part or all of the purchase price in escrow, you do not include any part of
it in gross sales until you actually or constructively receive it. However, upon completion of the terms of the contract and
the escrow agreement, you will have taxable income, even if you do not accept the money until the next year.
Sales returns and allowances.
Credits you allow customers for returned merchandise and any other allowances you make on sales are deductions from
gross sales in figuring net sales.
Special rules dealing with an accrual method of accounting for payments received in advance are discussed in chapter
If you receive insurance or another type of reimbursement for a casualty or theft loss, you must subtract it from
the loss when you figure your deduction. You cannot deduct the reimbursed part of a casualty or theft loss.
For information on casualty or theft losses, see Publication 547, Casualties, Disasters, and Thefts.
