Understanding Depreciation: It May Be More Simple Than You Think
Depreciation is defined as a portion of the cost that reflects
the use of a fixed asset during an accounting period. A fixed
asset is an item that has a useful life of over one year. An
accounting period is usually a month, quarter, six months or
one year. Let’s say you bought a desk for your office on
January 1, for $1000 and it was determined that the desk had a
useful life of seven years. Using a one year accounting period
and the “straight-line” method of depreciation, the portion of
the cost to be depreciated would be one-seventh of $1000, or
$142.86.
Most non-accountants roll their eyes and shudder when the topic
of “depreciation” comes up. This is where the line in the sand
is drawn. Depreciation is far too complicated to try and figure
out, or so it seems to many. But is it really? Surely the
definition of depreciation mentioned above is not that
difficult to comprehend. If you look closely you will see that
there are five pieces of information you must have in order to
determine the amount of depreciation you can deduct in one
year. They are:
-The nature of the item purchased (the desk).
-The date the item was placed in service (Jan 1).
-The cost of the item ($1000).
-The useful life of the item (seven years).
-The method of depreciation to be used (straight-line)
The first three are easy to figure out, the second two are also
easy but require a little research. How do you figure out the
useful life of an item? Let me regress for a moment. There is
“book depreciation” which is based on the real useful life of
an item, and there is the IRS version of what constitutes the
useful life of an item. A business that is concerned with
accurately allocating its costs so that it can get a true
picture of net profit will use book depreciation on its
financial statements.
However, for tax purposes the business is required to use the
IRS method. The IRS may have shorter or longer useful lives for
fixed assets causing a higher or lower depreciation write-off.
The higher the write-off, the less tax a business pays. The
long and short of it is that you end up having to create a book
financial statement and a tax financial statement. So, most
small businesses that aren’t concerned with a precise
measurement of their net profit use the IRS method on their
books. This means that all you have to do is look in IRS
Publication 946 to find the useful life of a particular item.
The last piece of information you need is found by determining
the method of depreciation to use. Most often it will be one of
two methods: the “straight-line” method or an accelerated method
called the “double-declining balance” method. Let’s briefly
discuss these two methods:
Straight-line
This is the simple method mentioned in the definition above.
Just take the cost of the item, divide it by the useful life
and you’ve got the answer. Yes, you will have to adjust the
depreciation for the first year you placed the item in service
and for the last year when you removed the item from service.
For instance, if your depreciation for one year was $150 and
you placed the item in service on April 1 then divide $150 by
12 (months) and multiply $12.50 by 9 (months) to get $112.50.
If you removed the item on February 28 then your deduction will
only be $25.00 (2 x $12.50).
Double-declining balance
The idea behind this method is that when an item is purchased
new, you will use up more of it in the earlier years of its
life, therefore, justifying a higher depreciation deduction in
the earlier years. With this method, simply divide the cost of
the item by the useful life years as in the straight-line
method. Then, multiply that result by 2 (double) in the first
year. The second year, take the cost of the item and subtract
the accumulated depreciation. Next, divide that result by the
useful life and multiply that result by 2, and so on for each
remaining year.
But, wait! You don’t have to do this. The IRS provides tables
that have the percentages worked out for each year of the two
different methods. Not only that, they have set up special
first year “conventions” that assume you purchased your
depreciable fixed assets on June 30. This is called the
one-half year convention. The idea behind this is that you may
have bought some items earlier than June 30 and some after that
date. So, to make it easy to figure out, they assume the higher
and lower depreciation amounts will all average out.
Actually, the IRS doesn’t even call it depreciation anymore.
They call it “cost recovery”. Let’s face it. This is a
political tool. Congress giveth and taketh away. They have been
playing with this system for years. If they want to stimulate
growth in business they will shorten the useful life of assets
so businesses can attain a higher write-off. If they are not in
the mood, they will extend the useful life of an item. A good
example is the 39 years set for the useful life of commercial
property. This means that if you lease a building for your
business and make improvements, those improvements have to be
depreciated over 39 years. Now congress is working on a bill to
drop that down to 15 years for leasehold improvements.
Before December 31, 1986 we had ACRS or Accelerated Cost
Recovery System. Currently, we have MACRS or Modified
Accelerated Cost Recovery System. Every time congress tweaks
the rules they give it a different name.
Keep in mind there are different schedules for different
properties. For instance, residential real property is
depreciated over twenty-seven and one-half years and
non-residential real property is depreciated over thirty-nine
years. In addition, if more than forty percent of your total
fixed asset purchases occurred in the last quarter of the year,
then, you must use a mid-quarter convention. This convention
assumes that your purchases made in the last quarter of the
year were made on November 15. This prevents you from buying a
big expensive piece of equipment on December 31 and treating it
as though it were purchased on June 30 and gaining a larger
depreciation expense.
Understanding how basic depreciation works can be valuable to
the small business owner because it helps to know the tax
implications when planning for capital equipment purchases.
