Cost basis methods
Understanding Cost Basis in Cryptocurrency Trading
Welcome to the world of cryptocurrency trading! One of the most important, and often confusing, concepts for any trader – especially when it comes to taxes – is *cost basis*. Simply put, your cost basis is the original price you paid for a cryptocurrency. Keeping track of it is *crucial* for accurately calculating your profits and losses when you eventually sell your crypto. This guide will walk you through everything you need to know, in plain English.
Why Does Cost Basis Matter?
Imagine you buy 1 Bitcoin (BTC) for $20,000. Later, the price goes up, and you sell it for $30,000. Your profit is $10,000, right? Yes, but the tax authorities need to know *exactly* how you arrived at that $10,000 figure. That's where cost basis comes in.
Without accurate cost basis records, you could overpay your taxes or, worse, run into trouble with the tax authorities. It also helps you understand your *actual* profit on each trade, which is vital for improving your trading strategy.
Common Cost Basis Methods
There are several ways to calculate your cost basis, and the method you choose can significantly impact your tax liability. Here are some of the most common:
- First-In, First-Out (FIFO):* This is the default method used by many tax authorities. It assumes you sell the *oldest* coins you own first. Using the example above, if you bought BTC at $20,000 and later bought more at $25,000, when you sell, the $20,000 BTC is considered sold first.
- Last-In, First-Out (LIFO):* This method assumes you sell the *newest* coins you own first. In the same scenario, the $25,000 BTC would be considered sold first. *Note:* LIFO is not permitted for tax purposes in all jurisdictions.
- Specific Identification:* This allows you to choose *exactly* which coins you're selling. This is the most precise method, but also the most record-keeping intensive. You need to be able to specifically identify the date and price of the coins you're selling.
- Average Cost:* This method calculates the average cost of all your coins. You add up the total cost of all your purchases and divide by the total number of coins.
A Comparison of Cost Basis Methods
Let's look at an example to illustrate the differences. Suppose you made three purchases of Ethereum (ETH):
- Purchase 1: 1 ETH at $1,000
- Purchase 2: 1 ETH at $1,500
- Purchase 3: 1 ETH at $2,000
You then sell 1 ETH for $2,500. How does the cost basis affect your calculation?
| Method | Cost Basis | Profit/Loss |
|---|---|---|
| FIFO | $1,000 | $1,500 |
| LIFO | $2,000 | $500 |
| Specific Identification (Selling Purchase 1) | $1,000 | $1,500 |
| Average Cost (($1000+$1500+$2000)/3) | $1,500 | $1,000 |
As you can see, the method you choose drastically impacts your reported profit.
Practical Steps for Tracking Cost Basis
1. **Choose a Method:** Select a cost basis method and stick with it consistently. Consult a tax professional to determine the best method for your situation. 2. **Record Every Transaction:** Keep detailed records of every purchase, sale, trade, and any other transaction involving cryptocurrency. This should include:
* Date of the transaction * Amount of cryptocurrency involved * Price per coin * Transaction fees
3. **Use a Cryptocurrency Tax Software:** There are many software options available (like CoinTracking, Koinly, or TaxBit) that can automate cost basis tracking and tax reporting. 4. **Spreadsheet:** For simpler tracking, create a spreadsheet with columns for date, purchase/sale, quantity, price, and fees. 5. **Exchange Reports:** Many cryptocurrency exchanges like Register now, Start trading, Join BingX, Open account and BitMEX provide transaction history reports you can download and use for tracking.
Important Considerations
- **Wash Sale Rule:** Be aware of the wash sale rule, which prevents you from claiming a loss if you repurchase the same cryptocurrency within 30 days of selling it.
- **Airdrops & Forks:** Airdrops (receiving free tokens) and forks (splitting of a blockchain) can create taxable events. Understand how to calculate the cost basis for these events.
- **Staking & Mining:** Rewards from staking and mining are also taxable.
- **Gifts & Donations:** Gifting or donating cryptocurrency has tax implications.
- **DeFi (Decentralized Finance):** Transactions in DeFi can be complex and require careful cost basis tracking.
