Cryptocurrency Tax Reporting: A Guide for Taxpayers

The IRS treats cryptocurrency as property for tax purposes, meaning that general tax principles applicable to property transactions apply to cryptocurrency transactions. This treatment was clarified in IRS Notice 2014-21, which stated that virtual currency is treated as property for federal tax purposes and that general tax principles applicable to property transactions apply to transactions using virtual currency.

This property treatment means that cryptocurrency transactions can trigger taxable events, and understanding when these events occur and how to report them is essential for compliance. The IRS has increased enforcement efforts in this area, including requiring cryptocurrency exchanges to report transactions to the IRS and adding a question about virtual currency transactions on Form 1040.

How Cryptocurrency Is Taxed

When you sell, exchange, or use cryptocurrency, you may recognize a capital gain or loss. The character of the gain or loss depends on how long you held the cryptocurrency before the transaction. If you held the cryptocurrency for more than one year, gains are generally long-term capital gains, which are subject to preferential tax rates (currently 0%, 15%, or 20% depending on your income level, plus a 3.8% net investment income tax for higher-income taxpayers).

If you held the cryptocurrency for one year or less, gains are short-term capital gains, which are taxed at ordinary income tax rates. This can result in significantly higher taxes, particularly for higher-income taxpayers. The holding period is determined from the date you acquired the cryptocurrency to the date you disposed of it.

The amount of gain or loss is calculated by subtracting your basis (generally what you paid for the cryptocurrency, including fees) from the amount you receive in the transaction (the fair market value of what you receive, less any fees). If you received cryptocurrency as payment for services or through mining, your basis is generally the fair market value of the cryptocurrency at the time you received it.

If you held multiple units of the same cryptocurrency that you acquired at different times and for different prices, you'll need to determine which units you're disposing of to calculate your basis. You can use specific identification (if you can identify which units you sold), first-in-first-out (FIFO), or another method, but you must use the method consistently.

Reporting Requirements

You must report cryptocurrency transactions on your tax return. Capital gains and losses from cryptocurrency transactions are reported on Form 8949, Sales and Other Dispositions of Capital Assets, with the totals carried to Schedule D, Capital Gains and Losses. You'll need to identify each transaction, including the date acquired, date sold, cost basis, sales proceeds, and gain or loss.

If you received cryptocurrency as payment for services or goods, you must report it as ordinary income at its fair market value on the date you received it. This income is reported on the appropriate line of your Form 1040, depending on the nature of the income (for example, as business income on Schedule C if it's from a trade or business, or as other income if it's from casual transactions).

If you mine cryptocurrency, the fair market value of the cryptocurrency you receive is included in your gross income as ordinary income on the date you receive it. If you're engaged in a trade or business of mining, you can deduct expenses related to mining, such as electricity costs and equipment depreciation. However, these expenses are subject to the normal limitations on business deductions.

The IRS has added a question on Form 1040 asking whether you received, sold, exchanged, or otherwise disposed of any financial interest in any virtual currency during the tax year. You must answer this question accurately. Answering "no" when you should answer "yes" can result in penalties, and it may also extend the statute of limitations for assessment.

Common Transaction Types

Several types of cryptocurrency transactions can trigger tax consequences. Selling cryptocurrency for cash (U.S. dollars or other fiat currency) is a taxable event that results in a capital gain or loss. Trading one cryptocurrency for another (for example, trading Bitcoin for Ethereum) is also a taxable event. The fair market value of the cryptocurrency you receive is treated as the amount realized, and you must calculate your gain or loss based on your basis in the cryptocurrency you disposed of.

Using cryptocurrency to purchase goods or services is a taxable event. You're treated as having sold the cryptocurrency for its fair market value at the time of the purchase, and you must recognize gain or loss on that deemed sale. This means that every time you use cryptocurrency to buy something, you may have a tax reporting obligation.

Receiving cryptocurrency as payment for services or goods is also a taxable event, as you must include the fair market value of the cryptocurrency in your gross income. Receiving cryptocurrency through mining, staking, or other activities also results in income inclusion at the fair market value when received.

However, simply holding cryptocurrency is not a taxable event. You don't recognize income when the value of your cryptocurrency increases while you hold it. Income or gain is only recognized when you dispose of the cryptocurrency through a sale, exchange, or use.

Record Keeping

It's important to maintain detailed records of all cryptocurrency transactions, including dates, fair market values, transaction costs (fees), and the nature of each transaction. Many cryptocurrency exchanges provide transaction histories that can help with reporting, but these histories may not always be complete or may not provide all information needed for tax reporting.

You should maintain records showing when you acquired cryptocurrency, how much you paid for it (including fees), when you disposed of it, and what you received for it. If you received cryptocurrency through mining, staking, or as payment, you should record the fair market value at the time you received it.

The fair market value of cryptocurrency at the time of a transaction can be determined from cryptocurrency exchanges or other sources that provide pricing information. You should document the source you used to determine fair market value and be consistent in your approach.

Good record keeping is essential not only for accurate tax reporting but also for defending your position if the IRS questions your reporting. The complexity of cryptocurrency transactions and the IRS's increased enforcement efforts make detailed records particularly important.

Penalties for Non-Compliance

Failure to properly report cryptocurrency transactions can result in penalties for accuracy-related issues, failure to file required forms, and in some cases, criminal penalties. Accuracy-related penalties apply if there is an underpayment of tax due to negligence or disregard of rules, or if there is a substantial understatement of tax.

The penalty is generally 20% of the underpayment, though it can be 40% in cases of gross valuation misstatements or undisclosed foreign financial assets. These penalties can be substantial, particularly given that cryptocurrency transactions can involve significant gains.

Failure to file Form 8949 or Schedule D when required can result in failure-to-file penalties, and failure to pay tax when due can result in failure-to-pay penalties. These penalties accrue over time and can add significantly to your tax liability.

In cases of willful failure to file returns or pay tax, or willful attempt to evade tax, criminal penalties may apply. These can include fines and imprisonment. While criminal prosecution is relatively rare, the potential consequences make compliance essential.

Given the complexity of cryptocurrency tax reporting and the IRS's increased enforcement efforts, it's important to take these obligations seriously and to maintain good records. If you have failed to report cryptocurrency transactions in prior years, you should consider consulting with a tax professional about options for coming into compliance, as various disclosure programs may be available.
