crypto forks and airdrops

In short

A friend of mine woke up one morning to find free coins sitting in his wallet, and he asked me if he owed anything on them. If you hold crypto, you may meet the same surprise someday. The Internal Revenue Service has said that new coins from a fork or an airdrop can count as income. The amount is the fair market value on the day the holder gains control of the coins. Control means you can sell them, send them, or trade them. A good record holds the date, the amount, and the price that day. That price becomes your cost basis, which is the starting number used to figure gain or loss when you sell later. Free does not always mean tax free.

The whole of it

What it is

I once watched a neighbor argue over a fence line, and it struck me that crypto forks are a bit like that, with two people looking at the same property and deciding to go separate ways. A fork happens when a blockchain, which is the shared public ledger behind a coin, splits into two chains. One side keeps the old rules. The other follows new ones. If you held coins before the split, you may end up holding coins on both chains.

An airdrop is a gift of a different sort. A project sends new tokens to many wallets at once, often to promote itself, and you might get them because you held a certain coin or used a certain service. Sometimes you never asked for them at all.

If you are holding coins and wondering what these events mean for you, here is the plain answer. The law treats them as property you received. The IRS spelled this out in Revenue Ruling 2019-24 and in Notice 2014-21. Those are the primary sources, and they are worth reading for yourself.

How it works

You have probably heard the phrase "taxable event," and it sounds scarier than it is. It just means a moment when the tax code takes notice. Under Revenue Ruling 2019-24, a hard fork alone creates no income. Income arises only if you receive new coins from it. If the new coins land in a wallet you control, you have income once you have dominion and control over them, which the IRS describes as the ability to transfer, sell, exchange, or otherwise dispose of the coins.

Timing matters here. Say a fork happens on a Friday, but your exchange does not credit the new coins until the next month. Under the ruling, you generally have income when the coins show up and you can use them. Before that, you may not have control at all.

The amount of income is the fair market value of the new coins at that moment. That same figure becomes your basis. When you later sell, your gain or loss is the sale price minus that basis. If you hold the coins more than one year after receiving them, the gain is long term. Sell sooner, and it is short term, taxed at ordinary rates.

Now a quiet point many folks miss. Your original coins do not change in basis because of the fork. Only the new coins get a fresh one.

The numbers, and where to find yours

Some of these numbers shift each year, and I would not trust my memory over the official page. Your ordinary income tax rate depends on your bracket, and the brackets are set by law. For the current figures, see the IRS tax rate tables, which list the brackets for your filing status. The long term capital gains rates are also set by law and change with income. Your own bracket is the current figure, which the official source publishes each year. The long term capital gains rate that applies to you is the current figure, which the official source publishes each year.

There is one more number to find, and it is the fair market value of the coins on the day you gained control. Exchanges and wallet services often show a price history, and price trackers do as well. Pick a reasonable source, note which one you used, and keep a screenshot. The IRS does not name one required source. So write down how you got your figure.

The tax return asks about this, too. Form 1040 asks the filer a digital asset question, and the filer answers it yes or no each year. The IRS instructions for Form 1040 show how that question is worded and where it sits for the current year.

A worked example

Let me tell you about a woman named Marlene. She is a nurse who makes $52,000 a year, and a few years back she bought 2 units of a coin at $1,000 each. Her total cost was 2 units at $1,000, or $2,000.

One spring day, the coin forked. Her exchange later credited her with 10 units of the new coin. On the day the coins landed in her account, they traded at $12 each. Marlene could now sell them. She had control.

Her income from the fork is 10 units at $12 each, which is $120. She reports that $120 as other income for the year. Her basis in the new coins is also $120, or $12 a unit.

Eight months later she sold all 10 new units at $15 each. The sale brought in 10 units at $15, which is $150. Her gain is $150 minus her $120 basis, which is $30. She held the coins less than a year, so the $30 is a short term gain, and she pays tax on it at her ordinary rate.

Add it up. She reported $120 of income at the start and $30 of gain at the end, so $120 plus $30 is $150 of total taxable amounts, even though the coins arrived free. The original 2 units still carry their $2,000 basis, and the fork changed nothing there.

Small numbers, I know. Real life can run bigger, but the steps stay the same.

Where it goes wrong

Honest folks stumble here, and I would not want you to feel foolish if it happens. The first slip is forgetting the free coins altogether. They arrive quietly, and nobody sends a bill, yet the income may still count in the year they arrive.

The second slip is a missing record. Without the date and the price, a person cannot show a basis, and a later sale can look like pure gain with a basis of zero. That raises the tax bill for no good reason.

A third trouble is guessing the wrong date. Control is the key, not the date of the fork itself. If the coins sat locked or unclaimed, the answer may differ. The IRS said the ruling addressed a specific set of facts, and your facts could be different. Read the source, and ask a tax pro when in doubt.

Airdrops bring their own wrinkle. Some tokens arrive with no value at all, or a value too small to find. Some come from scam projects, hoping you will click something. Sending or selling an unknown token can bring risk. I am not telling anyone what to do with a token. I am only saying that how it works and what it costs can differ by case.

Last, state tax rules may differ from federal ones. Check your state tax agency for its own rules.

Questions to answer before you leave this page

Do you know the exact day your wallet or exchange gave you control of any new coins? Have you saved the price you used, the source for that price, and a screenshot? Did you record the income in the year the coins arrived, and not the year you sold them? Do you know which bracket you sit in, and what the IRS tax rate tables say for your filing status? Can you show the basis of your original coins and the basis of the new ones, kept apart? Have you read the digital asset question on Form 1040 and answered it with care? And if your case looks different from the one in Revenue Ruling 2019-24, who will you ask for help before you file?
