Most crypto tax advice was written for a world where the IRS could not see your wallet. That world is ending, and 2026 is the tax year when the picture finishes coming into focus. Brokers must now report what you paid for the coins they sold, and the wash sale rule reaches crypto. Most people still run the 2021 playbook, where “I haven’t sold anything, so I don’t owe anything” felt like a loophole. It never was one, and this year it is much less of one.
What the IRS can see now, and what it still cannot
Form 1099-DA is the new reporting form for digital asset sales, and it is phased in. For 2025, brokers reported gross proceeds only. For 2026, they must also report cost basis, but only for what the rules call covered securities: units you bought through that broker after January 1, 2025. The first forms carrying basis data arrive in early 2027.
Everything else is still your job. Coins bought before 2025. Coins moved into a self-custody wallet. Trades on a decentralized exchange. Crypto received as payment for a freelance invoice. None of that came through a brokerage account, so no broker reports a cost basis for it. The consequence is bigger than the form: digital asset sales now reach the IRS as third-party data. If your return does not match what your broker reported, you get a letter, and it does not go away because you ignore it.
What actually triggers a tax
The IRS has treated crypto as property, not currency, since 2014. Everything else follows from that:
- Buying crypto with dollars is not taxable. It establishes your cost basis instead.
- Selling, swapping, or spending it is a disposal. Trading Bitcoin for Ethereum is two taxable events, not one.
- Holding period decides the rate. More than a year is long-term. Less than a year is short-term, taxed at your ordinary income rate.
- Receiving crypto as income is ordinary income, taxed at receipt. Staking rewards, airdrops, mined coins, and lending interest all count, valued at fair market value when you gained control.
- A hard fork is usually not income, as long as your ownership of the new coin does not change.
That fourth bullet is where most self-directed investors get it wrong. The trigger for income is not selling. It is receiving.
Staking: the mistake that produces a notice
Revenue Ruling 2023-14 is the document that matters if you stake. Rewards are ordinary income at fair market value when you have dominion and control over them, and the ruling goes further than most people expect: it applies even when the tokens are still locked in a validator and you cannot sell them yet. Unsellable is not the same as not received.
The tax on a staker can be measured on a number that never becomes cash. The amount you report becomes your cost basis, and the holding period on reward coins starts the day you received them, so selling them later is usually a short-term gain.
The reporting gap turns this into a problem. Depending on the platform, staking income may show on the 1099-DA, appear on a separate line, or not be reported at all. Most people report it themselves, and the classic failure is waiting until the year they sell. Rewards received in 2026 are 2026 income, valued in 2026.
January’s change: the wash sale rule arrives
Congress extended the wash sale rule to digital assets in 2022 but gave the IRS room to work out the mechanics. Those mechanics landed: the per se rules now apply to digital asset transactions in taxable years beginning after January 1, 2026.
In plain terms: sell a coin at a loss and buy the same coin back within 30 days, and the loss is disallowed and added to the basis of the replacement units. You do not lose the money, you postpone it. One question is still open: whether Bitcoin and Ethereum count as “substantially identical,” which would make a crypto-to-crypto swap a wash sale too. The IRS has not answered. Treat the same-coin version as disallowed and the cross-coin version as unusable for planning.
This quietly breaks a popular trick: rotating a loss from one token into another, which worked for years because the rule did not reach crypto. The adjustment also shows up on the 1099-DA and in most tax software, so if you adjust by hand as well, you can double-count it. And the ceiling nobody mentions: net capital losses offset only $3,000 of ordinary income in a year, or $1,000 with no gains at all. The rest carries forward.
How to actually do this without a CPA-sized headache
- Pull the paperwork first. Download every 1099-DA, total the reported proceeds, and make sure every dollar appears on Form 8949 and Schedule D. Mismatches are the most common reason people get letters.
- Rebuild the basis the broker will not report. For pre-2025 coins and anything off-exchange, combine exchange CSV exports with blockchain explorer records and your own notes. The purchase date also decides long-term versus short-term.
- Pick a cost basis method and be able to defend it. When you cannot identify specific units, FIFO is the default. Tax software often defaults to something else, like HIFO, which changes your gain. If you want specific identification, show which units you sold, and stay consistent year to year.
- Use software, but know when to hand it to a person. Read-only imports from exchanges generate your Form 8949, Schedule D, and Schedule 1 lines. DIY is fine with a handful of sales, no staking, and one exchange. Get help if you have hundreds of transactions across years, staking or airdrops, or numbers that do not tie to your 1099-DA. A preparer who does crypto work costs less than a mismatch you have to unwind later.
- Check the wash sale adjustment, then save everything. Export your full transaction history annually, because exchanges fold, and a dead exchange’s CSV is a hole in your basis story you cannot fill later.
When a notice arrives
Respond to it. A mismatch notice usually means your return and your broker’s numbers differ, which is a documentation problem, not a catastrophe. Reply before the deadline with your records, or file an amended return. Silence turns a small discrepancy into a collection problem.
2026 is the first year the IRS has a near-complete picture of many crypto transactions and the first year the wash sale rules reach them. The work is mostly boring rather than complicated: pull the forms, rebuild the basis nobody reported, put staking income in the year you received it, and drop the harvest plans that ignore January. If your situation is simple, this is a weekend with tax software. If not, a professional fee is smaller than a mismatch.
