US Crypto Taxes: An IRS Reporting Primer for Investors

For US taxpayers, crypto is property in the eyes of the IRS — which means most disposals trigger capital gains or losses, and certain earnings count as ordinary income. This primer covers the core mechanics, the forms involved, and what's changed for recent tax years. It's educational only — consult a CPA or tax professional for your situation.

How the IRS classifies crypto

The IRS treats cryptocurrency as property, not currency. The practical consequences:

• Selling, swapping, or spending crypto is a disposal that realizes a capital gain or loss.
• Earning crypto (staking rewards, mining, airdrops, interest, payment for services) is ordinary income at fair market value when received.
• Buying and holding, or moving between your own wallets, is not taxable.

Capital gains: short vs long term

The holding period matters a lot:

• Short-term (held ≤1 year): taxed at your ordinary income rate.
• Long-term (held >1 year): taxed at preferential long-term capital gains rates, which are typically much lower.

This is why tracking acquisition dates is essential — the same trade can be taxed very differently based on timing.

The forms you'll likely touch

• Form 8949: Where you list each disposal — date acquired, date sold, proceeds, cost basis, and gain/loss.
• Schedule D: Summarizes the totals from Form 8949.
• Schedule 1 / Schedule C: For crypto income (staking, mining as a hobby vs business, etc.).
• The digital asset question: Form 1040 asks directly whether you received, sold, or disposed of digital assets — answer it honestly.

The 1099-DA shift

Starting with recent tax years, US crypto brokers and exchanges began issuing Form 1099-DA to report digital asset proceeds to both you and the IRS. Key implications:

• The IRS now receives third-party data on your exchange activity — under-reporting is far riskier.
• Early 1099-DA reporting focuses on gross proceeds; cost-basis reporting is phasing in, so you may still need your own records to compute accurate gains.
• Always reconcile the 1099-DA against your own records — broker basis can be incomplete, especially for transferred-in assets.

Record-keeping for US filers

1. Log every transaction: date, asset, amount, USD value at the time, and fees.
2. Track cost basis carefully: the IRS generally expects specific identification or FIFO; your method affects your gains.
3. Don't forget on-chain and DeFi activity: airdrops, staking, and rewards are reportable income.
4. Keep records for years: retain documentation in case of audit.

Use the Tax Calculator for a rough estimate, but file with dedicated crypto tax software or a CPA.

Details US filers miss

• Crypto-to-crypto is taxable: swapping BTC for ETH is a disposal, even though no dollars were involved.
• Loss harvesting: realized losses offset gains and up to $3,000 of ordinary income per year, with the rest carried forward — a legitimate year-end strategy.
• Fees adjust basis: trading fees can be added to cost basis or netted from proceeds, slightly lowering taxable gains — one more reason to cut fees via rebates.

Tax rules evolve, and your situation is unique. This is a primer, not advice — work with a qualified CPA or tax professional for your filing.
