Crypto Tax Reporting Guide 2026: Form 1099-DA, Cost Basis, and What the IRS Expects

The one sentence that decides how your crypto is taxed

The IRS does not treat cryptocurrency as money. It treats it as property, and it has said so consistently since Notice 2014-21 back in 2014. Everything downstream flows from that single classification. Sell a coin, swap it for another, or spend it on a laptop, and you have triggered the same kind of capital gain or loss you would get from selling a stock.

The mistake I see most often is the belief that “I never cashed out to dollars, so there’s no tax.” That belief is expensive. If you traded Bitcoin for Ethereum, the IRS sees it as selling your Bitcoin at market value and buying Ethereum with the proceeds. Nothing left the exchange, and you still have a reportable event.

For 2025 and beyond, the enforcement picture got sharper. The new Form 1099-DA means exchanges now report your activity straight to the IRS, and the way you track cost basis shifted to a per-wallet system. The days of assuming nobody was watching are effectively over. This guide walks through the new rules the way I would explain them to a client sitting across the desk.

One note before we start: this is educational information, not personalized tax advice. Complicated situations deserve a conversation with a CPA or Enrolled Agent.

What is taxable, and what is not

Start by splitting crypto activity into two buckets: disposals (capital gains) and receipts (ordinary income). They carry different rates, different forms, and different math. Confuse them and you will misreport in both directions.

Here is the quick map.

Activity	Taxable?	Type of tax
Selling crypto for USD	Yes	Capital gain or loss
Trading coin A for coin B	Yes	Capital gain (you disposed of A)
Spending crypto on goods or services	Yes	Capital gain (spending = disposal)
Receiving staking, mining, or airdrop rewards	Yes	Ordinary income (value at receipt)
Getting paid in crypto for work	Yes	Ordinary income (wages or self-employment)
Buying with USD and holding	No	Unrealized, nothing to report
Moving crypto between your own wallets	No	No change in ownership
Donating to a qualified charity	No	May generate a deduction

The pivot word is disposal. Whether you sell, swap, or spend, once control of the coin leaves your hands you lock in the difference between its market value and your cost basis. A transfer between two wallets you both control is not a disposal, so it is not taxed. But even though the transfer itself is tax-free, the cost basis has to travel with the coin. Lose track of it and you can end up unable to prove what you paid, which means the IRS may treat your entire sale proceeds as gain.

Long-term versus short-term: the holding period decides the rate

Capital gains split sharply by how long you held the asset, and understanding that split is half of any real tax strategy.

• Short-term gains apply to coins held one year or less. They are taxed at ordinary income rates, up to 37%.
• Long-term gains apply to coins held more than one year. They get preferential rates of 0%, 15%, or 20%, depending on your taxable income.

High earners may owe the 3.8% Net Investment Income Tax on top of that. So the same $10,000 gain can leave very different amounts in your pocket depending on the calendar. When you are not in a hurry to sell, letting a position cross the one-year mark can drop your rate an entire tier.

Losses have their own use. Capital losses offset capital gains first, then up to $3,000 of net loss can offset ordinary income each year, with any remainder carried forward. The wash sale rule that governs stocks has not clearly been extended to crypto, which is why loss harvesting and immediate rebuying gets so much attention. Treat that gap as temporary, because Congress could close it. The broader mindset of taxing efficiency runs through my stock capital gains tax guide, and the same “basis versus proceeds” skeleton applies here.

The centerpiece of the new regime: Form 1099-DA

If one change reshaped crypto tax reporting for 2025, it is Form 1099-DA. Exchanges used to hand out inconsistent summaries, or nothing at all. Now they file a standardized form with the IRS and copy you at the same time.

The rollout runs on a staggered schedule.

Item	Applies from	First forms issued
Gross proceeds reporting	2025 transactions	Early 2026
Cost basis reporting	2026 transactions	Early 2027
DeFi / non-custodial brokers	Requirement repealed	Not applicable

A few things deserve your attention. First, 2025 forms report proceeds only, not cost basis. The exchange tells the IRS “this person sold $50,000 worth,” but not what those coins cost. If you do not supply the basis yourself, the IRS can read the full proceeds as gain. Proving what you paid is still your job.

Second, the broker reporting requirement for decentralized (DeFi) front-ends was repealed in 2025. A rule that would have forced DeFi platforms to issue 1099-DAs was overturned by a congressional resolution, so protocols like Uniswap do not send the form. That does not make DeFi activity tax-free. It only means no third party is reporting it, which puts even more weight on your own recordkeeping.

Third, once a 1099-DA lands, the IRS matching system compares it against your return automatically. Reconcile the form against your own records the moment it arrives, and be ready to explain any difference rather than getting a notice months later.

Cost basis methods and the wallet-by-wallet rule

How you assign cost basis is the most practical lever in the whole exercise. If you bought the same coin in several batches, the lot you are treated as selling changes the gain.

• FIFO (first-in, first-out): the earliest coins you bought are sold first. It is the default, and in a rising market it tends to surface the lowest basis and the biggest gain.
• Specific Identification: you name the exact lot at the time of sale, which lets you choose lots that minimize the taxable gain, as long as you have records to back it up.
• HIFO (highest-in, first-out): a flavor of Spec ID that sells your highest-cost lots first to shrink the current gain.

Now the pivotal 2025 change. Under Rev. Proc. 2024-28, effective January 1, 2025, you can no longer pool coins across all your wallets under the old universal method. Cost basis has to be tracked account by account, wallet by wallet.

In practice that means the $10,000 basis of Bitcoin bought on exchange A cannot be applied to Bitcoin you sell out of wallet B. To use Specific Identification, the lot you point to must actually sit in that wallet. The IRS offered a safe harbor to allocate pre-2025 lots to specific accounts by the end of 2024, and added transition relief for 2025 (Notice 2025-7). The direction is unmistakable: if you run multiple wallets, keep a separate basis ledger for each one.

Most individual investors lean on crypto tax software (CoinTracker, Koinly, and the like) at this point, because those tools pull exchange APIs and on-chain data and organize lots per wallet. Garbage in still means garbage out, though. Knowing the rules for each asset type is the real foundation, the same way it is when you weigh ETFs versus individual stocks inside a taxable account.

Staking, mining, and airdrops: the ordinary income side

If capital gains are about the moment you sell, ordinary income is about the moment you receive. Mix them up and you will double-count or under-count.

Staking rewards are ordinary income equal to the fair market value when you gain control of the coins. That same value becomes your cost basis. Sell later and you calculate a separate capital gain or loss on the difference. Income tax when received, capital gains tax when sold. Two bites.

Mining depends on scale. As a hobby, the value at receipt is ordinary income on Schedule 1. As a business, it is self-employment income on Schedule C, which brings the 15.3% self-employment tax but also lets you deduct equipment, electricity, and other business costs.

Airdrops and hard forks are ordinary income at the value when the coins become available to you. Tokens that show up in your wallet unrequested still count once you can move them, which catches people off guard.

Income type	Taxed when	Character	Form
Staking rewards	Value at receipt	Ordinary income	Schedule 1 (or C)
Mining (hobby)	Value at receipt	Ordinary income	Schedule 1
Mining (business)	Value at receipt	Self-employment	Schedule C (SE tax)
Airdrops / hard forks	Value when available	Ordinary income	Schedule 1
Paid for work	Value at receipt	Wages or self-employment	W-2 or Schedule C

Filing mechanics: Form 8949 and Schedule D

Time to move it onto paper. Once the concepts click, knowing which box holds what keeps you from freezing at the return.

1. Form 8949: list each disposal on its own row. Asset, date acquired, date sold, proceeds, cost basis, gain or loss. Short-term (held one year or less) and long-term (held more than a year) go in separate sections.
2. Schedule D: summarize the 8949 totals, split into short-term and long-term. Your net capital gain or loss settles here.
3. Schedule 1 or Schedule C: report staking, airdrop, and other ordinary income here. A mining or crypto business runs through Schedule C and its self-employment tax.
4. Form 1040: answer the digital asset question honestly near the top. If you disposed of crypto or received it as income, the answer is yes.

Once your transaction count runs into the hundreds, filling out 8949 by hand stops being realistic. Tax software generates the form and some methods let you attach a summary. Verify the output with your own eyes anyway, especially rows where cost basis is blank (like 2025 sales on a 1099-DA), because those you have to fill in yourself. If you are new to the annual rhythm of deadlines and extensions, my tax filing deadline tips cover the calendar side.

Recordkeeping, common mistakes, and penalties

People who fail at crypto taxes almost always fail the same way: they keep no records. At minimum, capture the following for every transaction.

• Dates acquired and disposed
• USD fair market value at acquisition and at disposal
• Cost basis (including fees) and proceeds
• Transaction fees and gas (added to basis or netted from proceeds)
• Transfers between wallets and exchanges, so basis can be linked

Now the errors I watch repeat every filing season.

One: skipping crypto-to-crypto trades. People leave swaps off the return because they never cashed out. As covered above, a swap is a disposal.

Two: ignoring DeFi and staking income. No 1099-DA does not mean no tax. The reporting party is gone, the obligation is not.

Three: leaving the 1040 digital asset question blank. That empty box is a compliance flag on its own.

Four: failing to prove cost basis. Skip the transfer records and you can watch your full proceeds get treated as gain.

These gaps carry a price. Interest accrues on unpaid tax, and it stacks with a failure-to-file penalty, a failure-to-pay penalty, and an accuracy-related penalty (typically 20% of the underpayment). Willful evasion can escalate to civil fraud or criminal charges. On the flip side, if you honestly missed something, filing an amended return before the IRS reaches out cuts your risk dramatically. Taxes reward good records and clean timing, a theme that shows up whether you are running a small business or funding a 401(k) and IRA.
