Tax Record-Keeping:
Assistance and Guidelines
for Sole Proprietorships
To effectively run a business, a self-employed taxpayer must maintain
business records for tax purposes. This can be extremely daunting. In
many instances, the taxpayer does not know where to start. However,
the process can be greatly simplified with diligent record keeping.
The purpose of this packet is to provide self-employed taxpayers
particularly, sole proprietors with no employeessimple, easy to use
spreadsheets designed to help document daily income and expenses. If
these documents are correctly and continuously updated throughout
the course of a taxable year, the taxpayer will have a better
understanding of his taxable income. Additionally, this will provide a
tax professional much of the necessary information to ensure that the
taxpayer’s business receives the full extent of any available deductions.
These deductions reduce a taxpayer’s adjusted gross income, thereby
lowering the taxpayer’s overall tax liability for that year.
DISCLAIMER: This is not specific legal advice. The attached spreadsheets are for organizational
purposes and designed to assist a tax professional in preparing a self-employed taxpayers tax return.

Small Business Filing Requirements
If you are still reading this, then you are a sole proprietor with no
employees. As a sole proprietor, you must file a Form 1040 because
any profits that the business generates are considered your own
personal income. You must file a Form 1040 whether or not your
business is incorporated (LLC).
Form 1040 is the standard individual income tax return that most
Americans file every year. However, as a sole proprietor, Line 12
(“Business income (or loss)”) is particularly significant. In order to
properly calculate business income, the sole proprietor must complete
and attach Schedule C.
Stated simply, Schedule C accounts for all income and expenses
accrued during the course of business activities. The spreadsheets
attached to this document are designed to assist the sole proprietor in
completing the “Income” and “Expenses” section in Schedule C.
If applicable, in order to properly calculate Schedule C’s Line 13
(“Depreciation and Section 179 Expense Deduction”), the sole
proprietor must complete Form 4562. If applicable to the self-
employed taxpayer, some of the spreadsheets attached to this
document are designed to assist the sole proprietor (or the sole
proprietor’s accountant/tax professional) in calculating the proper
depreciation deduction. The depreciation deduction will lower the sole
proprietors tax liability for the year in question.

Filing Recap
o A sole proprietor must file a Form 1040.
o To properly complete a Form 1040, the sole
proprietor must complete Schedule C.
o To properly complete Schedule C, the sole
proprietor may need to complete Form 4562.
Due to the complexity of Form 4562
and
depreciation deductions generally, it is highly
recommended that the sole proprietor seek
professional tax assistance. Remember, business
expenses for professional tax advice may be
deductible as a business expense on
Schedule C.

Spreadsheet Summaries
This page briefly describes the spreadsheets and their
significance in the overall preparation of a sole proprietor’s tax
returns.
1
Income and Expense Log
The income and expense log is designed to assist the
sole proprietor in keeping track of income and
expenses relating to clients on a per-job basis. This
will assist in completing Schedule C.
Asset Log
The asset log plays an important role in calculating
immediate and future expense deductions. The
purpose of the asset log is to assist the user in
recording and keeping track of any and all business
related assets and equipment, and associated repair
and maintenance costs. By tracking old and new
business assets, the asset log assists the taxpayer (or
tax professional) in accurately completing Form
4562.
Additionally, the log records business related
“expenses and repairs” of assets. Expenses and
repairs may be deductible every tax year. The total
yearly expenses and repairs amount is to be inserted
in Line 21 of Schedule C.
Importantly, be sure to retain any and all receipts
associated with purchases and expenses; the IRS
requires that business purchases and expenses must
be substantiated (proven upon request by the IRS)
and a receipt is the easiest way to prove that the
expenses you claim are in fact true and accurate.
Additionally, any items listed must be acquired for
business use through purchase (not a gift).
Mileage Log
The mileage log allows the sole proprietor to take
advantage of the “travel” expense on Schedule C.
The mileage log is designed to assist in obtaining the
appropriate deduction for gasoline expenses related
2
to travel to and from a worksite, or in the course of
business. The amount of allowable deduction
requires the taxpayer to add all miles traveled for
business purposes and multiply them by the then
applicable "Standard Mileage Rate." In 2015, the
standard mileage rate was $0.575 per mile (note that
these standards change yearly). For example, if a
taxpayer drives 1000 business-related miles over the
course of the taxable year, she multiplies 1000 x .575,
leaving her with an allowable $575 travel expense.
Therefore, $575 would be inserted in Line 24a of
Schedule C labeled "Travel."
Supply Log
The supply log is designed to assist the sole
proprietor in keeping a detailed record of work-
related supplies on a per-job basis. Expenses for
supplies can be deducted on a yearly basis. This is
significant because, for example, if the taxpayer
purchases $1000 worth of masonry for a $1500 job
(and the masonry is the only expense), the net
taxable income from the job is $500 rather than
$1,500.
Miscellaneous Expense Log
The miscellaneous expense log is designed to assist
the taxpayer in completing the “Expense” portion of
Schedule C. There are several expenses considered
deductible within the taxable year. Importantly,
some of these deductible expenses may include; legal
and professional services (including tax preparation),
advertising, utilities, rental/lease payments, office
expenses, and contract labor, to name a few.
