======Basis======
Basis (also known as //[[Cost Basis]]// or //[[Tax Basis]]//) is a fundamental concept every investor must grasp. Think of it as the starting line for your investment's financial journey. In its simplest form, basis is the original value of an asset for tax purposes, typically the purchase price you paid. This includes not just the price of the shares, but also any commissions or fees you paid to acquire them. Why does this number matter so much? Because it's the critical figure you'll subtract from the sale price to determine your profit or loss. This profit is your //[[Capital Gain]]//, and the loss is your //[[Capital Loss]]//. Without knowing your basis, you're flying blind when it comes to taxes. A low basis on an investment that has soared in value is a sign of a successful pick, but it also signals a hefty potential tax bill when you sell. Understanding and accurately tracking your basis is not just tedious accounting; it's a cornerstone of smart, tax-efficient investing.
===== Why Basis is Your Best Friend at Tax Time =====
The relationship between what you sell an asset for and its basis determines whether you'll be writing a check to the government or getting a tax deduction. The math is beautifully simple:
**Sale Price - Basis = Capital Gain or Loss**
Let's make this real. Imagine you buy 100 shares of Coffee Co. at $50 per share and pay a $10 commission to your broker.
  * Your total basis isn't just $5,000 (100 shares x $50). It's $5,010, because you must include that pesky commission.
  * A year later, you sell all 100 shares for $70 each, for a total of $7,000.
  * Your taxable capital gain is: $7,000 (Sale Price) - $5,010 (Basis) = $1,990.
This $1,990 is the amount on which you'll owe capital gains tax. If you had sold the shares for $4,000, you would have a capital loss of $1,010, which could be used to offset other gains or even a small amount of your regular income.
===== The Ever-Changing Basis: Meet the Adjusted Basis =====
Just when you thought you had it figured out, basis can change over time. This new, modified figure is called the //[[Adjusted Basis]]//. It reflects events that occur during the life of your investment. Think of it as your original basis plus or minus a few key adjustments.
==== What Increases Your Basis? ====
Certain events add to your original cost, which is good news because a higher basis means a smaller taxable gain when you sell.
  * **Reinvested Dividends:** When you use a //[[Dividend Reinvestment Plan]]// (DRIP), you are essentially buying more shares with your dividend payout. Each purchase creates a new basis for those specific shares and increases your total basis in the position.
  * **Commissions and Fees:** As seen in our example, the cost to //buy// an asset is added to your basis.
  * **Capital Improvements (for Real Estate):** If you own an investment property and add a new roof, that cost is added to the property's basis, not treated as a simple repair expense.
==== What Decreases Your Basis? ====
Conversely, some events lower your basis, which can lead to a larger taxable gain down the road.
  * **Return of Capital Distributions:** A //[[Return of Capital]]// (ROC) is when a company gives you back a portion of your own investment money. Unlike a dividend, an ROC is not taxed in the year you receive it. Instead, it reduces your cost basis.
  * **Depreciation:** For income-producing property like real estate or equipment, tax rules allow or require you to take an annual //[[Depreciation]]// deduction. This deduction directly reduces your asset's basis.
===== Special Situations That Can Trip You Up =====
Investing life is full of curveballs that can complicate your basis calculation. Here are a few common ones to watch out for.
==== Inherited vs. Gifted Assets ====
  * **Inheritance:** When you inherit an asset, you often get a huge tax benefit called a //[[Stepped-up Basis]]//. The asset's basis is "stepped up" to its fair market value on the date of the original owner's death. If your uncle bought a stock for $5 that's worth $105 when he passes away, your basis becomes $105. You could sell it the next day for $105 and owe zero capital gains tax.
  * **Gifts:** Receiving a gifted asset is different. You generally receive a //[[Carryover Basis]]//, meaning you take on the giver's original basis. If your mother gifts you that same stock (which she bought for $5 and is now worth $105), your basis is her original $5. Ouch.
==== Corporate Shenanigans: Splits and Spinoffs ====
  * **Stock Splits:** A //[[Stock Split]]// doesn't change your total basis, but it does change your //per-share// basis. If you own 100 shares with a total basis of $2,000 ($20/share), a 2-for-1 split leaves you with 200 shares. Your total basis is still $2,000, but your per-share basis is now $10 ($2,000 / 200 shares).
  * **Spinoffs:** When a company spins off a division into a new, separate company, your basis in the original stock is allocated between the shares of the old company and the new one. Your broker typically provides the allocation formula.
==== The Wash Sale Rule ====
This one is a classic trap. The //[[Wash Sale]]// rule prevents you from selling a security at a loss and then buying it back within 30 days (before or after the sale) just to claim a tax deduction. If you trigger this rule, the loss is disallowed for that year. Instead, the amount of the disallowed loss is added to the basis of the new shares you purchased. This effectively postpones the tax benefit of the loss until you sell the new shares.
===== The Value Investor's Takeaway =====
For a value investor, "basis" isn't just a tax term; it's a scorecard and a strategic tool.
  * **Meticulous Record-Keeping is Non-Negotiable:** While brokers track basis, they don't have to for shares bought before 2011, and mistakes can happen. You are the ultimate keeper of your records. Use spreadsheets or software to track every purchase, sale, and dividend reinvestment.
  * **Sell Smarter, Not Harder:** If you've bought shares of a company at different times and prices, you have multiple "lots" with different basis points. This allows for tax-loss harvesting or strategic selling. You can instruct your broker to sell specific shares—for instance, the ones with the highest basis—to minimize your taxable gain. This is far more tax-efficient than the default //[[FIFO]]// (First-In, First-Out) method most brokers use. Other methods include //[[LIFO]]// (Last-In, First-Out).
  * **Embrace the "High-Class Problem":** If you've held a wonderful company for decades, your basis might be pennies compared to its current price. The resulting tax bill upon selling may seem daunting, but it's the direct result of a phenomenally successful investment. That's a problem any value investor should be thrilled to have.
