Four Types of Usage for
Expenses and Property
 “Personal-use” property refers to the function of
property. It means that the property is held for the
taxpayer’s own enjoyment.
 “Personal” property refers to the physical nature of the
property. It means that the property is mobile, i.e., not
affixed to “real” property.
The following examples illustrate the four types of
usage for expenses, personal property, and real property.

Tax Treatment for the
Four Types of Usage
The tax treatment for losses and expenses varies
according to their type of usage.
Usage
Tax Treatment for Losses and Expenses
Business
Unlimited deductions, except for passive activity
losses (usually offers the most favorable tax
treatment)
Hobby
Limited to net hobby income
Investment
Capital loss limited to $3,000; investment
expenses limited to net investment income
Personal
Generally not deductible unless specifically
allowable as with itemized deductions (usually
results in the least favorable tax treatment)
Chapter 6, Exhibit 2
CCH Federal Taxation Basic Principles

Business Expenses—Seven Criteria
Business expenses are generally deductible without limitation when the following seven
criteria are met:
1.
Purpose is business related. If part business, part personal, use a reasonable allocation (e.g., mileage for automobiles).
2.
Ordinary (common, acceptable response to a business situation) and necessary (helpful, but not essential). (Welch v.
Helvering)
3.
Reasonable in amount. This is of main concern to closely held corporations, particularly regarding officers’ salaries. One
way to substantiate reasonableness is by presenting documentation of similar expenses by comparable businesses.
4.
Capital expenditures are not deductible (but may be depreciable). Sales tax on capital expenditures must be capitalized.
5.
Activity must be related to a business, not to investments, hobbies, or personal-use property. There must be (1) an intent to
make a profit the IRS is generally satisfied if 3 of 5 years are profitable) and (2) an entrepreneurial effort.
6.
Exempt income must not be connected with the business expense (e.g., business interest expense on a loan used to buy local
utility bonds is not deductible).
7.
Public policy must not be violated by the expense. Fines, kickbacks, bribes, etc. are not deductible. (Tank Truck Rentals)

Defending Tax Treatment for a
Business Activity
Whether losses or expenses receive favorable business
treatment is an issue of fact. The taxpayer wins if the
facts meet the statutory requirements; the IRS wins if
they do not. Reg. §1.183-2(b) provides the statutory
framework. It states that all facts and circumstances of
an activity are to be taken into account and that no one
factor makes the determination. It lists the following
nine factors that should normally be taken into account
in making the determination. Taxpayers and the IRS
should make their factual arguments within the context
of these nine factors.

Hobby Expenses—Template for Problem Solving
If an activity is a hobby, expenses are deductible in the following three tiers:
Hobby income (Revenue - Cost of goods sold)
FIRST-TIER EXPENSES (reported on Schedule A)
–
Taxes (property tax and state and local income tax allocable to hobby)
–
Interest (interest on principal residence mortgages and home equity loans allocable
to hobby)
–
Casualty loss deductions (related to principal residence and allocable to hobby)
=
First-Tier Limit

–
THIRD-TIER EXPENSES (only if the second-tier limit is a positive value)

Home Office Deductions—
Template for Problem Solving
The rules for deducting home office expenses are similar to the hobby expense rules
except as follows:

Business expenses not related to the home office (e.g., advertising, wages) are
deductible without limitation before the three-tiered limitations take effect; hobby
expenses not related to the home office are subject to the second-tier limitation.

Self-employed persons report business expenses (deductible within the three-tiered
limitations) on Schedule C, not on Schedule A as is the case with hobby expenses.
Employed persons report unreimbursed business expenses (deductible within the threetiered limitations) on Schedule A (similar to the hobby rules).

Property Taxes—
Allocation Between Buyer and Seller
 Property taxes are generally deductible without limitation if
they are “ad valorem” (i.e., based on value).
 Property taxes should be allocated between seller and buyer
based on the number of days held, not the number of
months held. Furthermore, property taxes allocable to the
day of closing are attributable to the buyer, not the seller.

Depreciation–
Code Sec. 179 Election
Expense election. In 2003, an election may be made to
expense up to $25,000 of tangible business and personal
property rather than capitalize and depreciate it. This election
must be made when the return is filed; it cannot be made on
an amended return. If an election is made and a portion of the
$25,000 creates a business loss, that portion creating the loss
must be carried over to the next year’s return.
Phaseout. The expense allowance is phased out on a dollarfor-dollar basis for purchases exceeding $200,000.

Amortization
Amortizable property. Intangible property that is
used for business and is of limited life (e.g.,
goodwill, going-concern value, licenses, covenants
not to compete, franchises, trademarks, patents, and
copyrights).

years.

materials or products for quality control, management studies,
consumer surveys, advertising, or promotions.

immediately, or if elected, amortized over a minimum of 5 years.

dissimilar business. Instead, try to postpone as
much of them as possible until after the doors are
open for business. The postponement may result

Student Loan Interest
Qualified Student Loans. To be eligible for the deduction, the
education loan must be used solely to pay for any of the
following expenses: tuition, student activity fees, room and
board, books and supplies, and other related expenses.
Note: The qualified purpose of a student loan is similar in
scope to the qualified purpose of “education withdrawals”
from ordinary IRAs and education IRAs. On the other hand,
the student loan is much broader in scope than the Hope
Scholarship or Lifetime Learning Credits.
