basis

What It Is

Basis refers to the original price of an asset. It is sometimes called cost basis or tax basis.

How It Works

Let's assume you purchase 100 shares of Company XYZ stock for $5 per share and you pay a $10 commission for the purchase. Your basis would be:

(100 x $5) + $10 = $510

Income realized from the asset, including dividends and capital distributions (even if they are reinvested rather than received in cash) increase the basis. Thus, in the above example, if your stock paid a $1-per-share dividend every year for three years, your basis would increase to:

$510 + (100 x $1 x 3) = $810

Money spent on improvements to an asset (such as certain home improvements) are added to the asset's basis, and depreciation on the asset is subtracted from the cost basis.

Why It Matters

An asset's basis becomes very important when the owner sells the asset. The difference between the sale price and the basis is called a capital gain (if the sale price is higher than the cost basis) or a capital loss (if the sale price is lower than the basis). Capital gains are generally only taxable when the investor actually sells the asset. Realized losses can often offset these gains and thus lower the investor's potential capital-gains taxes. The length of time the asset is held, among other things, determines the tax effect of the gain or loss. Changes in tax rates also may influence an investor's concern about basis.

An asset's basis is usually based on its original purchase price, but sometimes people inherit assets rather than purchase them. In these cases, the basis of the asset becomes the value of the asset at the time the investor inherits it (this is called a step-up in basis).

Often, investors accumulate shares of the same stock at different prices over time. Because of this, when the investor sells some of the shares, he or she must identify which shares from the "inventory" were sold in order to calculate capital gains or losses. In general, investors want to minimize taxable gains by selling the shares with the highest basis first. However, if the investor cannot identify which shares are which, the IRS requires use of the first-in-first-out (FIFO) method, meaning that the investor must assume he or she first sells the shares that are held the longest. These older shares may not have the highest basis of the investor's inventory of shares, and thus the method could inflate the investor's tax bill.

What It Is

Adjusted basis refers to the increase or decrease in an asset's value due to depreciation or capital enhancements.

How It Works

From the time an asset is acquired until the time it is sold, an asset experiences a number of events which affect its value. These events can cause an increase or decrease in the asset's total value. An asset's adjusted basis takes the base price of an asset and adjusts it for changes in value reflecting enhancements and or depreciation. For instance, a given asset purchased for $100 that is sold one year later after having experienced $10 in depreciation and $50 in improvements would have an adjusted basis of $100 - $10 + $50 = $140.

Why It Matters

In the event an asset is sold, the adjusted basis is needed for tax purposes as it is used to calculate the capital gain or loss.
