Crypto and Digital Asset Taxes in 2026: What Your CPA Needs to Know

· Guide · 6 min read

Cryptocurrency and digital assets are now a line item on the Form 1040 that every U.S. taxpayer must answer, regardless of whether they own any. For those who do own crypto, the tax complexity has grown substantially — Form 1099-DA reporting from exchanges began for 2025 transactions, staking and DeFi income creates recurring ordinary income events, and the IRS has ramped enforcement. A CPA who has kept current with digital asset guidance is no longer optional for serious crypto holders; it's the difference between correctly filed returns and an audit notice. This guide covers what's taxable, what your CPA needs from you, and what questions to ask when evaluating whether an accountant has real crypto competency versus surface familiarity.

How the IRS Treats Cryptocurrency in 2026

The foundational IRS position — established in Notice 2014-21 and expanded through subsequent guidance — is that cryptocurrency is property, not currency. This has several practical consequences:

Form 1099-DA: The Reporting Shift That Changes Everything

The Infrastructure Investment and Jobs Act of 2021 added digital asset broker reporting requirements to the tax code. Starting with 2025 tax year transactions (reported on 2025 returns filed in early 2026), brokers are required to issue Form 1099-DA covering customer sales and exchanges. The IRS receives a copy.

This matters because prior to 1099-DA, the IRS had limited visibility into individual crypto transactions. Many taxpayers who held crypto through exchanges without selling reported nothing, even though staking rewards, interest, and promotions were technically taxable income. The 1099-DA closes this gap — but only for transactions through reporting brokers. Decentralized exchange activity, off-chain transactions, and transactions through non-U.S. platforms without U.S. customers still have limited IRS visibility, though blockchain analysis tools give the IRS growing ability to trace wallet activity.

Taxable Events: A Practical Checklist

When you bring crypto records to your CPA, every one of these event types creates a potential tax obligation:

Cost Basis Tracking: Why It's Harder Than It Looks

Accurate gain and loss calculation requires knowing your cost basis for every unit of crypto you sell. For most people, this means tracking: the date and price of every acquisition (purchase, airdrop, staking reward, trade receipt), the date and proceeds of every disposition (sale, trade, spend), and matching each disposal to specific acquisition lots under your chosen accounting method.

Most people with meaningful crypto activity have hundreds or thousands of transactions across multiple exchanges and wallets. The major crypto tax software platforms — Koinly, CoinTracker, TaxBit, CryptoTrader.Tax (now CoinLedger) — can ingest exchange transaction history via API or CSV and calculate gain/loss using FIFO, HIFO, or specific identification. These platforms cost $50–$400 per year depending on transaction volume and are essentially required for anyone with more than a handful of transactions.

However, crypto tax software is not foolproof. Missing cost basis (from exchange closures, incomplete records, wallet transfers that break the chain) is the most common problem. If you transferred crypto between wallets or exchanges without keeping records, the software may assume zero cost basis — dramatically overstating your gains. Your CPA needs to review the output, not just accept it.

DeFi-Specific Tax Issues

Decentralized finance creates tax complexity that centralized exchange activity doesn't. The key issues your CPA needs to understand:

What to Ask When Evaluating a CPA's Crypto Knowledge

Many CPAs claim crypto competency. Fewer have meaningfully worked through complex crypto returns. Questions that distinguish real expertise from surface familiarity:

NFT-Specific Tax Considerations

NFTs (non-fungible tokens) are taxed similarly to crypto in most respects, but with additional nuance:

For small business owners who are also crypto holders, our guide on Section 179 and bonus depreciation is relevant if you're mining or treating crypto as business property.

Frequently Asked Questions

Is cryptocurrency taxed as income or capital gains?
Both, depending on how you acquired it. Crypto received as payment for work, mining rewards, staking income, and airdrops is taxed as ordinary income at the time of receipt. When you later sell, trade, or spend crypto, the difference between your cost basis and the sale price triggers a capital gain or loss — short-term (held under 1 year, taxed as ordinary income) or long-term (held over 1 year, taxed at 0%, 15%, or 20% depending on your income bracket).
Do I have to report crypto on my taxes if I didn't sell anything?
If you only held cryptocurrency without selling, trading, or spending it, you generally have no taxable event to report — but the question on Schedule B (and on the main 1040 since 2019) asks whether you received, sold, exchanged, or disposed of any digital asset. If you received crypto as income (staking, mining, salary, airdrops), those receipts are reportable even if you never sold. Form 1099-DA, required from brokers starting in 2025, will increasingly surface activity your prior returns may not have caught.
What is Form 1099-DA and how does it affect my crypto taxes?
Form 1099-DA is a new IRS reporting form that crypto brokers (exchanges like Coinbase, Kraken, and others) began issuing for 2025 tax year transactions. It reports your crypto sales, exchanges, and disposals similarly to how Form 1099-B reports stock sales. The IRS receives a copy, which means underreporting crypto income is increasingly detectable. For 2026 tax year returns, expect near-universal 1099-DA issuance from major exchanges.
What cost basis method should I use for crypto taxes?
The most common methods are FIFO (first in, first out), HIFO (highest in, first out), and specific identification. HIFO typically minimizes gains by selling your highest-cost-basis coins first; specific identification allows similar results with more documentation. The IRS requires consistent application of your chosen method and, starting with 2025 transactions, requires you to specify your method to your broker before disposing of assets. A CPA can help model which method produces the best outcome given your portfolio.
Are DeFi transactions taxable?
Yes, most DeFi transactions are taxable events. Swapping one token for another on a decentralized exchange (Uniswap, SushiSwap) triggers the same capital gain or loss as selling on a centralized exchange. Providing liquidity to a pool and receiving LP tokens may be treated as a disposition of the underlying assets. Yield from DeFi lending or liquidity mining is generally ordinary income. The IRS has not issued comprehensive DeFi guidance, so treatment of edge cases (liquidity pool entries/exits, protocol-specific mechanics) involves some professional judgment.
