How Is Bitcoin Taxed in the US? A General Guide

Key takeaways

• For US federal tax purposes, the IRS treats bitcoin as property, not as currency. Selling, trading or spending it can be a taxable event.
• Buying bitcoin with dollars and holding it, or moving it between wallets you own, is generally not a taxable event by itself.
• Gains and losses are measured against your cost basis, and the length of time you held the coin can affect how the result is treated.
• Good records are the foundation of accurate reporting. Keep dates, amounts and what each transaction was for.
• This is a general orientation, not tax advice. Rules change and depend on your situation, so confirm details with the IRS and a qualified tax adviser.

How does the IRS treat bitcoin?

The IRS treats bitcoin and other virtual currency as property for federal tax purposes, not as currency. This is the single most useful fact to understand, because it explains most of the rest.

When something is property, the usual question is what happens when you dispose of it. If you sold a share of stock, you would compare what you received with what you paid. Bitcoin follows the same logic. If you got more than you paid, you may have a gain. If you got less, you may have a loss. If you still hold it, nothing has been realized yet, even if the price has moved.

This treatment is summarized in Is Bitcoin Regulated in the US?. The article you are reading goes further into how it plays out. State tax rules can differ from the federal ones, and tax treatment outside the US is a separate matter. This guide covers US federal concepts only, and it deliberately gives no rates, thresholds or dollar amounts, because those change and depend on your circumstances. The IRS home page is https://www.irs.gov/.

What counts as a taxable event?

A taxable event is generally an action that “realizes” a gain or loss because you have disposed of the bitcoin. The common ones are straightforward.

Selling bitcoin for dollars. This is the classic case. The difference between what you received and your cost basis is generally a gain or a loss.

Trading bitcoin for another crypto asset. Swapping one asset for another is generally treated as a disposal of the first. This surprises people who think of a trade as a pure swap with no sale.

Spending bitcoin on goods or services. Using bitcoin to pay for something is generally treated as disposing of property at its value at the time. Buying a coffee with bitcoin can therefore create a small gain or loss that has to be accounted for, in principle, however small it is.

Receiving bitcoin as income. Getting paid in bitcoin, or earning it in certain ways, is covered in its own section below.

The treatment of other situations, such as gifts, inheritances, forks and airdrops, has its own rules. They are not covered here, and a tax professional is the right person for them.

What is generally not a taxable event?

Several common actions are generally not a sale, though you should still keep records.

Buying bitcoin with dollars and holding it. Acquiring bitcoin is not by itself a disposal. The tax questions start later, and the purchase details become your starting point for them.

Moving bitcoin between wallets you own. If you transfer coins from an exchange to your own wallet, or between your own wallets, you have not sold anything. This is one reason a transfer should be recorded as a transfer, not left looking like a sale. Network fees can raise their own questions, and a tax professional can say how they apply.

Holding through price changes. A rise or fall in price that you have not acted on is not generally reported. This is the idea behind “unrealized” gains and losses.

Transferring to or from a retirement account. Coins held inside a retirement account follow different rules, discussed in Can You Buy Bitcoin in an IRA?. That is a separate topic.

The key habit is to ask whether you disposed of the asset or simply held or moved it. If you are uncertain, ask before you act, not after.

What is cost basis?

Cost basis is, in general terms, what you paid to acquire the asset, including certain costs of the purchase. It is the starting point for working out a gain or a loss.

If you paid more for a coin than you later received when you disposed of it, you have a loss. If you received more, you have a gain. The calculation is simple when you bought one amount once. It becomes more complicated if you bought at different times and different prices, and then sell part of your holding. In that case, which coins are treated as the ones sold can affect the result. The methods allowed and the rules for choosing among them are technical, and they have been subject to change, so this guide does not go into them. A qualified tax adviser can explain what applies to you.

Also remember that the cost basis does not disappear when you move coins between your own wallets. Your records need to follow the coins, so that years later you can still show what you paid and when.

What is the holding period?

The holding period is how long you owned the asset before you disposed of it. In general terms, US tax rules distinguish between short-term and long-term treatment of gains based on how long you held the property. The two can be taxed differently, which is why timing can matter.

This guide does not state the dividing line or the rates, because they are for the IRS and your adviser to confirm for the year in question. What is useful to understand is the concept: the date you acquired the coin and the date you disposed of it both matter, so both belong in your records. That is another reason an exchange statement on its own may not be enough if you have moved coins around.

What about income from bitcoin?

Not every receipt of bitcoin is a purchase. In some situations, bitcoin you receive is treated as income, which is a different category from a gain on a sale.

In general terms, this can include being paid for work or services in bitcoin, and income from mining as a business or activity. In those cases, the value of the bitcoin when you received it is generally relevant, and that value can also become the cost basis for a later sale. The result is that one coin can be involved in two tax events: one when it is received and another when it is later disposed of.

How different kinds of income, such as mining, pay from an employer, or other rewards, are classified and reported depends on the facts, so this article does not try to list them all. If you are a business owner, a freelancer or a miner, the details matter and a tax professional is worth consulting. The underlying activity of mining is described in Inside a Bitcoin Mining Operation.

What records should you keep?

Good records make everything else easier. Most problems come not from the rules, but from not being able to reconstruct what happened years earlier.

For each acquisition and each disposal, it helps to record:

• the date and time,
• the amount of bitcoin involved,
• what you paid or received in dollars at that time,
• any fees paid,
• where the coins came from or went to, and
• the purpose of the transaction, such as a purchase, a sale, a transfer between your own wallets, a payment or income.

Export exchange statements and transaction histories regularly, because exchanges can change what they offer and accounts can close. The public ledger, discussed in Is Bitcoin Private?, shows that something moved, but not the dollar value or the purpose.

This site does not recommend software for tracking. Whatever method you choose, check that its output matches your own records.

Does the tax return ask about bitcoin?

The federal individual income tax return has asked taxpayers about digital asset activity, and the reporting rules for digital assets have been expanding over time. Exchanges and brokers also have reporting obligations of their own, and these have been developing. What you must report depends on what you did during the year, and the forms and questions can change from year to year.

The reliable approach is to check the current instructions on the IRS website, https://www.irs.gov/, for the year you are filing, and to answer the digital asset question accurately. A qualified tax professional can apply the rules to your specific facts.

Where taxes fit in the bigger picture

Taxes are one of several practical considerations when holding bitcoin, alongside security and custody. If you are new, the Start Here path covers the fundamentals, and How to Buy and Secure Bitcoin covers the practical side of acquiring and protecting it, including why it helps to keep clear records from your first purchase. If you are considering borrowing against your coins, see Bitcoin-Backed Loans and Mortgages for why a liquidation can create a tax event you did not choose.

This is general information. Tax law is detailed, it changes, and your own circumstances determine the outcome. A qualified tax adviser, such as a CPA or enrolled agent, is the right person to rely on for your own return.
