Cost basis is the original value or purchase price of an asset or investment for tax purposes. It's your starting point when investing: the original purchase price of an investment, plus any extras like fees or reinvested dividends. This number becomes crucial at tax time when you need to figure out whether you've made or lost money on an investment.
When you sell an investment, the IRS wants to know how much profit you made (or loss you took). The only way to calculate this is by comparing your selling price to what you originally paid—your cost basis. It's similar to how a store tracks its profit by subtracting what it paid for inventory from the sales price.
For example, if you bought 100 shares of stock for $10 each ($1,000 total), paying no commission or fees, andও sold them lat🌟er for $15 each ($1,500 total), your cost basis of $1,000 helps you calculate your $500 profit. While this is straightforward, the cost basis can get trickier when you factor in reinvested dividends, stock splits, or buying more shares over time.
Key Takeaways
- The cost basis is the asset or investment's initial value or purchase price used for tax purposes.
- It helps determine capital gains tax, calculated on the difference between the asset's cost basis and its sale price.
- The smaller your cost basis, the more taxes you might owe.
- Most brokerages track cost basis and report gains and losses to the IRS using Form 1099-B.
- The general default method for determining cost basis by brokerages is called "first in, first out" (FIFO), though other methods like specific share identification may also be used.
Understanding Cost Basis
Cost basis is the foundation of smart tax planning for investors. While relatively straightforward, proper tracking can save investors thousands in unnecessary taxes over time. The cost basis starts as the original cost of an asset for tax purposes, which is the first purchase price. However, over time, your cost basis might change, similar to how the value of a house changes when you add a new roof or remodel your k♈itchen.
Several events can adjust your cost basis. For example, when a company splits its stock—e.g., turning one share into two— your cost basis gets split too. If you originally paid $100 for one share and the company does a two-for-one s🐷plit, your cost basis becomes $50 per share (though it totals the same in any event). Dividends that you reinvest also increase your cost basis because you're essentiall💎y buying more shares.
When you eventually sell an investment, the Internal Revenue Service (IRS) looks at your cost basis to determine if you owe taxes. If you sell an asset for more than your cost basis, you've made a profit (澳洲幸运5官方开奖结果体彩网:capital gain) and m🧜ight owe taxes. Hold your investment for more than a year, and most owe a lower tax rate than if you sold it quickly.
Tip
Most investors focus on potential returns when buying stocks, but understanding your cost basis can be as important. It's not about what you make; it's what you can keep after taxes.
First In, First Out vs. Other Reporting Methods
The IRS allows cost basis to be determined using the first in, first out (FIFO) method (the default) or specific share identification. The latter enables the investor to identify which shares were sold. However, the designation must be made in advance to the brokerage—outlining which shares are being sold. Here's how they differ:
FIFO is a method where the shares bought first are considered the first ones sold. This is the default method for most brokerages and is straightforward, especially when managing multiple lots of the same stock bought over time. Using FIFO can also be an advantage in a rising market because the oldest shares typically have a lower purchase price, leading to higher cap🔥ital gains. However, this also means potentially higher tax liabilities since the gains are greater when those earlier, lower-cost shares are sold.
Specific share identification allows investors to choose which shares they want to sell from their portfolio. This method provides greater flexibility for managing capital gains or losses since it lets you select shares with a higher purchase price to minimize gains or shares with a lower price t🔯o maximize reported gains when it suits tax planning needs.
澳洲幸运5官方开奖结果体彩网:Average cost basis is used for mutual funds and certain exchange-traded funds (ETFs). With this approach, the investor determines the average price paid for all shares in an account by adding up the total cost of all shares purchased and dividing it by the number of🐬 shares owned. This creates a single average price per share, simplifying the calculation of gains or losses when shares are sold.
Tax Reporting Cost Basis
Brokerage firms are required to report the price paid for taxable securities to the IRS for most 澳洲幸运5官方开奖结果体彩网:securities, which are reported using FIFO. Brokerages, however, are only required to re𒅌port an asset sale to the IRS if the investment was made after the following dates:
- Jan. 1, 2011, for equities
- Jan. 1, 2012, for mutual funds, exchange-traded funds, and dividend reinvestment banks
- Jan. 1, 2014, for other specific securities, including most fixed-income securities (generally bonds) and options
Determining the initial cost basis of securities is relatively simple for 🦂a single purchase. However, it becomes more complex with subsequent purchases and sales, which can occur as part of various trading strategies or for portfolio rebalancing. Accurate tracking of these transactions is crucial, especially for those who want to optimize their tax outcomes. Although brokerages assist with this tracking, investors should keep their own records to cross-check for accuracy, especially if switching brokers or transferring accounts.
Fast Fact
Brokerages use 澳洲幸运5官方开奖结果体彩网:Form 1099-B to report realized gains and🤡 losses for a tax year, which they send t🐽o you and the IRS.
Calculating Cost Basis
Every investment will start with a cost basis, and if it ends up being the only purchase, determining the cost basis will just involve a review of the original purchase price. The IRS also allows you to include the cost of a trade, such as a stock-trade commission, to reduce the eventual sales price.
Once you make further purchases, you'll need to track each purchase date and value. For tax purposes, the default method used by the IRS and most brokerages reporting gains and losses is FIFO.
Tip
Many investors forget 澳洲幸运5官方开奖结果体彩网:reinvested dividends increase their cost basis, and they end up paying more taxes as a꧟ result.
Calculating the Cost Basis of Shares
For example, let's assume you bought 100 shares of XYZ for $20 per share in June and then bought 50 XYZ shares in September for $15 per share.
If you sold 120 shares, your costꩵ basis using the FIFO method would be as follows:
(100 × $20 per share) + (20 × $15 per share) = $2,300
The average cost method may also apply and is the total dollar amount of shares purchased, divided by the number of s💃hares purchased. If you sold 1ꦇ20 shares, your average cost basis would be as follows:
120 × [(100 × $20 per share) + (50 × $15 per share)]/ 150 = $2,200
Bonds are unique since the🌸 purchase price above or below par must be amortized until maturity.
For mutual funds, there might be 澳洲幸运5官方开奖结果体彩网:taxable events each year if the funds are held in taxable (nonqualified) accounts, such as distributions. A 澳洲幸运5官方开奖结果体彩网:custodian will track all amounts, or a mutual fund firm will provide guidance.
Fast Fact
In addition to the IRS requirement to report capital gains, it's wise to track how an investment has performed over time. Savvy investors know what they have paid for a security and how much in taxes they have to pay if they sell it.
Calculating the Cost Basis of Bonds
When calculating cost basis for bonds, it's a bit different. Let's say you bought a $10,000 bond for $10,500 (above par value). That $500 premium doesn't just disappeaꦺr—it gets spread out (amortized) over the life of the bond.
Here's a simplified example:
- Bond face value: $10,000
- Purchase price: $10,500
- Years until maturity: Five
- Annual amortization: $100 ($500 ÷ 5 years)
Each year, your cost basis decreases by $100 as the bond moves toward its face value at maturity. This matters because it affects how much of your interest payments ar🍌e taxable.
Important
Bond cost basis calculations can t💦rip up e🎃ven experienced investors. The key is understanding how amortization gradually adjusts your basis over time.
Cal🎉culating the Cost Basis of Mutual Fund Shares
Mutual funds can be tricky because they have ongoing distributions and you might bᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚuy shares at diff🍰erent times. You have two main ways to calculate the cost basis:
1. FIFO method: This would be exactly like the stock꧑ exampl💦e above:
First 100 shares at $20 = $2,000. The next 20 shares at $15 = $300. The total cost basis = $2,300
2. Average cost method: Over time, your total investment is ($2,000 + $750) = $2,750. Since your total shares are 150 and the average cost per share is $2,750 ÷ 150 = $18.33, the cost basis for 120 shares is as follows: 120 × $18.33 = $2,200.
Tip
People often confuse repairs with improvements. Fixing a leaky faucet doesn't affect your cost basis, but replacing all the plumbing does.
Calculating the Cost Basis of Real Estate
The real estate cost basis involves much more than just your purchase price. You'll also be adding up everything you've invested in the property. Here's how to calculate it:
澳洲幸运5官方开奖结果体彩网: 1. Starting point:
- Purchase price of the property
- Plus closing costs (title insurance, legal fees, recording fees)
- Real estate commissions paid
2. Then add any capital improvements:
- New roof or HVAC system
- Kitchen or bathroom remodels
- Room additions
- New windows or siding
- Landscaping improvements
澳洲幸运5官方开奖结果体彩网: Let's walk through an example:
- Purchase price: $300,000
- Closing costs: $5,000
- New roof: $15,000
- Kitchen remodel: $40,000
澳洲幸运5官方开奖结果体彩网: Total cost basis: $360,000
Spec൩ial adjustments can be made in theꦆ following examples:
- Subtract insurance payments received for casualty losses
- Subtract depreciation if you've used the property for business
- Add special assessments for local improvements like sidewalks
How Life Events and Corporate Actions Affღect the Co﷽st Basis
Calculating the cost basis gets more complicated if there are corporate actions or special situations like inheriting stock. Let's review some of these situations:
Bankruptcy
When a company declares bankruptcy, this doesn't mean your shares are worthless for tax purposes. The two main types of bankruptcy that affect your cost basis differently are:
- Chapter 7 bankruptcy: The company completely shuts down, and your shares become worthless. You can claim a loss on your taxes based on your original cost basis.
- Chapter 11 bankruptcy: The company stays in business while reorganizing its debts. Your shares might still trade and hold some value, so you'll need to keep tracking your original cost basis.
Sometimes, if you hold bonds in a company going through Chapter 11, you might receive new common stock in exchange for your bﷺonds. In this case, your new cost basis becomes the fair market value of the stock on the day you receive it.
Dividends and Reinvestment
To calculate the equity cost basis for a sto💙ck without dividends, you add the purchase price per𒈔 share plus fees per share. Reinvesting dividends increases the cost basis of the holding because dividends are used to buy more shares.
Let's say you invest $1,000 (plus a $10 trading fee) in 10 shares of ABC company. Over two years, you reinvest $600 in dividends ($200 year one, $400 year two).
Your new cost basis would be $1,610 ($1,000 + $10 fee + $600 in 澳洲幸运5官方开奖结果体彩网:dividends). This matters because dividends are taxed in the year when you receive them. So, including them in your cost basis prevents being double-taxed.
Inherited and Gifted Stocks
Inherited stocks get a "stepped-up" basis—meaning your cost basis is the stock's 澳洲幸运5官方开奖结果体彩网:fair market value on the date of the benefactor's death.
For gifted stocks, you typically use the original owner's cost basis. However, if the stock was worth less when you received it than when the giver bought it, you might use the lower value as your cost basis.
Fast Fact
The stepped-up basis for inherited stock is among the most valuable 💯tax benefits in the tax code—but only if you document it properly.
Mergers and Acquisitions
When a company you own is acquired by another company, the acquiring company will issue stock, cash, or a combination of both to complete the purchase. Payouts for cash will result inไ havingꦬ to realize a portion as a gain and pay taxes on it.
The issuance of shares will likely keep capital gains or losses as unrealized, but it will be necessary to track the new cost. Companies guide the percentages and breakdowns. The same rules also apply when a company spins out a divisi൲on into its own new company. Some of the tax costs will go with the new firm, and you (or your tax advisor) will need to dete🍰rmine the percentage, which the company will provide.
For example, if XYZ buys ABC and gives you two shares of XYZ for each ABC share, your cost basis gets recalculated based on the exchange ratio. Companies file details about these changes with the U.S. Securities and Exchange Commission in Form S-4.
Stock Splits
When a company doubles its shares (called a two-for-one split), your cost basis gets split too. If you owned 100 shares at $20 each ($2,000 total), after the split you'd have 200 shares with a cost basis of $10 each.
However, your total cost basis remains $2,000.
How To Track Your Cost Basis
Tracking your cost basis tracking is much easier with convenient phone apps and today's brokerage and tax platforms. Most investors rely on their brokerage firms, which use computer systems to track every purchase, sale, dividend reinvestment, and corporate action affecting your investments. These records are typically available online and reported directly to the IRS.
However, it's best not to rely only on your broker. Consider using personal finance software like Quicken or even a simple Google or Excel spreadsheet to maintain your own records. Several websites, including GainsKeeper and Netbasis, also offeꦬr specialized 🐲cost-basis tracking services. Having your own records becomes especially important if you switch brokers or need to verify old transactions.
The key to accurate cost basis tracking is de🌟veloping good habits:
- Save confirmation statements from every purchase and sale
- Keep records of all dividend reinvestments
- Document any corporate actions affecting your investments
- Store all these records for at least three years after selling an investment
- Review your broker's cost basis calculations periodically for accuracy
These details mightꦿ seem tedious, but they can save you money and hassle when tax time comes around or if you need to verify your investment gains or losses.
How's the Cost Basis for Dividend Reinvestment Plans (DRIPs) Plans Calculated?
DRIPs create a new tax lot or purchase record every time your dividends are used to buy more shares. This means each reinvestment becomes part of your cost basis. For this reason, many investors prefer to keep their DRIP investments in tax-advantaged individual retirement accounts, where they don't need to track every reinvestment for tax purposes.
What Is the Capital Gains Tax?
Capital gains tax ꦛis the tax levied on profits from the sale of capital assets. These are significant assets that can realize a profit when they are sold, such as investments, art, or real estate. Gains from the sale of these assets are long-term if the asset was held for more th𓄧an a year before it was sold.
澳洲幸运5官方开奖结果体彩网:Long-term capital gains are taxed at the capital gains rate, which is 0%, 15%, or 20%, depending on your income bracket. Gains for capital assets that were held for less than a year are considered short-term capital gains and are taxed at your ordinary income rate.
When Do You Owe Capital Gains Taxes?
You owe the tax on capital gains for the year in which you realize the gain. Capital gains taxes are owed on the profits from the sale of most investments if they are held for at least one year. If the investments are held for less than one year, the profits are considered short-term gains and are taxed as 澳洲幸运5官方开奖结果体彩网:ordinary income. For most people, that's a higher rate.
What Are Dividends?
A dividend is the distribution of a company's earnings to its shareholders and is determined by the company's board of directors. Dividends are often distributed quarterly and may be paid out as cash or as reinvestment in 澳洲幸运5官方开奖结果体彩网:additional stock.
The Bottom Line
Cost basis is the original value or purchase price of an asset oওr investment for tax purposes. It is used to calculate capital gains or losses, which is the difference between the selling and purchase prices of capital assets. Tracking cost basis is required for tax purposes.
While modern brokerages handle most of the tracking automatically, understanding your cost basis helps you make smarter investment decisions, from choosing when to sell shares to deciding whether to reinvest dividends. Whether you're buying your first stock or managing multiple investments, keeping good records of your cost basis can save you money at tax time. A bonus is that tracking the cost basis gives you a clear sense of which investments have proven profitable.
