Understanding the cost basis of your cryptocurrency investments is crucial for accurate tax filings and avoiding potential penalties. In the world of digital assets, "cost basis" refers to the initial amount paid for cryptocurrencies, which is essential for calculating capital gains or losses when these assets are sold or disposed of. With increasing scrutiny from tax authorities globally, precise reporting of your crypto transactions has never been more important. This article will guide you through various methods to determine your crypto cost basis, ensuring you stay compliant and optimize your tax outcomes.

What is Cost Basis in Crypto?

In the context of cryptocurrencies, “cost basis” refers to the initial outlay paid for digital assets. It is an important consideration when calculating capital gains or losses from the sale or disposal of cryptocurrencies. The capital gains or losses on an investor’s crypto sale are calculated as the selling price minus the cost basis.

To avoid tax complications, the cost basis must be reported accurately; otherwise, one may have an underpayment or overpayment of taxes, which may result in fines from the tax authorities. Furthermore, accurate reporting is much more important due to the increased scrutiny that tax authorities throughout the world are placing on crypto transactions.

Tax authorities require individuals to declare their cryptocurrency transactions for tax purposes in numerous jurisdictions, including the United States. Penalties and audits may result from inaccurate cost basis reporting. As a result, investors must keep thorough records of all of their cryptocurrency transactions, including the purchase price, the date of the transaction, and any additional costs.

Common Methods for Calculating Crypto Cost Basis

There are various methods to calculate the cost basis for cryptocurrencies, as discussed below:

Specific Identification

Specific identification is a popular method for calculating the cost basis of cryptocurrency holdings. Investors are able to determine and monitor the cost basis of each cryptocurrency asset separately using this method. Investors who are selling or disposing of crypto assets indicate the exact units they are selling and the price at which they were purchased.

Because this method accounts for the specific purchase price of the units being sold, it enables an accurate cost basis calculation. It is especially helpful for investors who wish to carefully choose what units to sell depending on their cost basis and holding duration to optimize their tax outcomes.

To understand how this method works, let’s consider a hypothetical example: An investor purchased 1 Bitcoin (BTC) on Jan. 1, 2023, for $30,000 and 1 BTC on May 1, 2023, for $50,000. They can select which particular purchase to utilize as their cost basis if they choose to sell 1 BTC.

To implement a specific identification method, every crypto transaction must be meticulously documented, including the purchase price, date, and any associated costs. Compared to other approaches, it may also be more difficult and time-consuming to execute, even if it provides the highest level of accuracy in cost basis reporting.

First-In, First-Out (FIFO)

Another common way to calculate the cost basis of crypto holdings is the “first-in, first-out” (FIFO) method. Under FIFO, the crypto assets that are bought first will be sold first. This approach assumes that the oldest cryptocurrency holdings are the ones being sold or otherwise disposed of, which makes transaction tracking easier.

Let’s assume that on Jan. 1, 2023, an investor paid $30,000 to acquire 1 BTC; on May 1, 2023, they paid $50,000. The oldest purchase price — i.e., $30,000 — is automatically used as the cost basis when they sell 1 BTC.

Even though FIFO is simple to implement, there are situations in which it may result in increased tax costs due to the possibility that assets with lower purchase prices would be sold, increasing capital gains and, in turn, taxes.

Despite this drawback, FIFO remains a popular option for many investors because it is straightforward to apply; people who are not actively trading cryptocurrencies prefer such a method for calculating their tax liabilities.

Last-In, First-Out (LIFO)

As opposed to FIFO, “last-in, first-out” (LIFO) assumes the crypto assets that were most recently bought will be sold first, indicating that the most recent purchase price serves as the asset’s cost basis.

Let’s assume that on Jan. 1, 2023, an investor paid $30,000 to acquire 1 BTC, and on May 1, 2023, they paid $50,000. When they sell 1 BTC, the cost basis is automatically the most recent purchase price.

In some circumstances, the LIFO approach may be beneficial, particularly when prices are rising. Investors may be able to reduce their capital gains and, in turn, their tax obligations by selling their most recent acquisitions first. However, in cases where the most recent assets acquired have a lower cost basis than older assets, LIFO can also result in greater taxes.

Compared to FIFO, the LIFO approach is less frequently employed to determine crypto tax liabilities despite possible tax benefits. This is because LIFO may be less desirable to many investors due to its potential complexity and the need for more thorough record-keeping.

Highest-In, First-Out (HIFO)

A strategic way for determining the cost basis of crypto holdings for taxation purposes, the “highest-in, first-out” (HIFO) method assumes that the most expensive cryptocurrency assets are sold first (in contrast to FIFO and LIFO).

Investors can strategically reduce their capital gains and, thereby, their tax liability by selling their assets on the highest-cost basis first. When there is a price appreciation and the cost basis of the assets being sold is higher, this strategy is especially advantageous.

To understand how the HIFO method works, let’s assume that an investor purchased 1 BTC on Jan. 1, 2023, for $30,000, followed by 1 BTC on May 1, 2023, for $50,000. When they sell 1 BTC, the cost basis is automatically the highest purchase price.

Although HIFO can lead to lower capital gains taxes, it may not be a good fit for all investors, as it requires careful record-keeping. Additionally, investors should ensure they keep proper documents to back up their calculations because tax authorities may scrutinize the use of HIFO. Notwithstanding these drawbacks, investors wishing to reduce their tax obligations on crypto transactions may utilize the HIFO approach.

Average Cost Basis (ACB)

By using this technique, investors may calculate the average price of all the cryptocurrencies they own. The cost basis of the sold crypto assets is then established using this average price.

Let’s assume an investor purchased 2 BTC, 1 at $30,000 (Jan. 1, 2023) and 1 at $50,000 (May 1, 2023). Their average cost basis would be calculated as follows:

The average cost approach offers a middle ground between potential tax optimization and simplicity. Adopting an average price for all holdings of the same cryptocurrency makes calculating the cost base simpler. Investors who frequently buy and sell cryptocurrencies and wish to expedite their record-keeping procedures may find this strategy helpful.

The average cost approach is still a popular choice among investors despite perhaps not providing the same level of tax efficiency as FIFO or HIFO, for example. While still providing a reasonable degree of accuracy in cost basis
