Publication 587
taxmap/pubs/p587009.htm#en_us_publink1000226434The filledin forms for John Stephens that follow show how to
report deductions for the business use of your home if you file Schedule C (Form
1040).
taxmap/pubs/p587009.htm#en_us_publink1000226435Based on the following facts, John completes Form 4562 as follows:
taxmap/pubs/p587009.htm#en_us_publink1000226436John began using his home for business in January of this year.
He purchased a new computer and filing cabinet to use in his business. The
computer, used 100% for business, cost $3,200. The filing cabinet cost $600.
John elects to claim the section 179 deduction for both items.
John completes Part I of Form 4562. He enters the cost of both
the computer and filing cabinet, $3,800, on line 2 and completes lines 4 and 5.
On line 6, he enters a description of each item, its cost, and the cost he
elects to expense. Line 11 is the smaller of line 5 ($250,000) or the taxable
income from all trades and businesses without regard to the section 179
deduction. Since he has no other business income, he adds line 31 of Schedule C
and the amount of the section 179 deduction ($3,800) for a total business income
of $27,871. This amount goes on line 11 since it is smaller than $250,000. He
enters $3,800 on line 12.
taxmap/pubs/p587009.htm#en_us_publink1000226437John converted to business use a desk and chair (furniture) he
had purchased in 2003 for personal purposes. In 2003, he paid $1,500 for them.
The total fair market value in 2010 is $550. The fair market value is less than
the cost, so his depreciable basis is $550.
Because the furniture is 7year property under MACRS, John enters
$550 in Part III, line 19c, column (c) of Form 4562. He completes columns (d)
through (f). He uses Table 4 in this publication or Table A1 in Publication 946
to find the rate of 14.29% for property placed in service during the first month
of the year. He multiplies $550 by 14.29% (.1429) and enters $79 on column (g).
taxmap/pubs/p587009.htm#en_us_publink1000226438This is the first year John used his home for business, so he
must figure the depreciation on line 19i. On line 19i, column (c), he enters
$11,000, the depreciable basis of the business part of his home. He began using
his home for business in January of 2010. (For a discussion on how he figures
his depreciation deduction, see
Step 3
under
Form 8829, Part II, later.) He enters $271 on line 19i, column (g).
taxmap/pubs/p587009.htm#en_us_publink1000226439John totals the amounts on line 12 and line 19 in column (g)
and enters the total on line 22. He enters both the section 179 deduction
($3,800) and the depreciation on the furniture ($79) on line 13 of Schedule C
(Form 1040). He enters the depreciation on his home ($271) on Form 8829, line
29.
taxmap/pubs/p587009.htm#en_us_publink1000226440John completes Schedule C as follows:
taxmap/pubs/p587009.htm#en_us_publink1000226441As discussed previously, John enters the amount from line 13,
Form 4562, for his section 179 deduction ($3,800) and the depreciation deduction
for his office furniture ($79) for a total of $3,879.
taxmap/pubs/p587009.htm#en_us_publink1000226442This amount is the interest on installment payments for the business
assets John uses in his home office.
taxmap/pubs/p587009.htm#en_us_publink1000226443John had a separate telephone line in his home office that he
used only for business. He can deduct $347 for the line.
taxmap/pubs/p587009.htm#en_us_publink1000226444On line 28, he totals all his expenses other than those for the
business use of his home, and then subtracts that total from his gross income.
He uses the result on line 29 to figure the deduction limit on his expenses for
the business use of his home. He enters that amount on Form 8829, line 8, and
then completes the form. He enters the amount of his home office deduction from
Form 8829, line 35, on Schedule C, line 30.
taxmap/pubs/p587009.htm#en_us_publink1000226445John uses one room of his home exclusively and regularly to meet
clients. In Part I of Form 8829 he shows that, based on the square footage, the
room is 10% of the total area of his home.
taxmap/pubs/p587009.htm#en_us_publink1000226446John uses Part II of Form 8829 to figure his allowable home office
deduction.
taxmap/pubs/p587009.htm#en_us_publink1000226447First, he figures the business part of expenses that would be
deductible even if he did not use part of his home for business. These expenses
($4,500 deductible mortgage interest and $1,000 real estate taxes) relate to his
entire home, so he enters them in column (b) on lines 10 and 11. He then
subtracts the $550 business part of these expenses (line 14) from his tentative
business profit (line 8). The result, $25,002 on line 15, is the most he can
deduct for his other home office expenses.
taxmap/pubs/p587009.htm#en_us_publink1000226448Next, he figures his deduction for operating expenses. He paid
$300 to have his office repainted. He enters this amount on line 19, column (a)
because it is a direct expense. All his other expenses ($400 homeowner's
insurance, $1,400 roof repairs, and $1,800 gas and electric) relate to his
entire home. Therefore, he enters them in column (b) on the appropriate lines as
indirect expenses. He adds the $300 direct expenses (line 22, column (a)) to the
$360 total for indirect expenses (line 23) and enters the total, $660, on line
25. This amount is less than his deduction limit, so he can deduct it in full.
The $24,342 balance of his deduction limit (line 27) is the most he can deduct
for depreciation.
taxmap/pubs/p587009.htm#en_us_publink1000226449Next, he figures his allowable depreciation deduction for the
business use of his home in Part III of Form 8829. The adjusted basis of his
home is $130,000, which is less than the fair market value of $160,000. He
figures the value of the land to be $20,000. He subtracts the land value from
the adjusted basis. He multiplies the result ($110,000) by the percentage on
line 7 to get the depreciable basis of the business part of his home ($11,000).
He began using the office in January, so he uses Table 2 in this
publication or Table A7a in Appendix A of Publication 946. The depreciation
percentage for the first year of the recovery period for assets placed in
service in the first month is 2.461%. His depreciation deduction for 2010 (line
41) is $271 (.02461 × $11,000). He enters that amount in Part II on lines
29 and 31. This is less than the available balance of his deduction limit (line
27), so he can deduct the full amount as depreciation. John also must complete
Form 4562 for 2010, so he enters $271 on line 19i, column (g) of Form 4562. See
Form 4562,
earlier.
taxmap/pubs/p587009.htm#en_us_publink1000226450Finally, he figures his total deduction for his home office by
adding together his otherwise deductible expenses (line 14), his operating
expenses (line 26), and depreciation (line 32). He enters the result, $1,481, on
lines 33 and 35, and on Schedule C, line 30.
