Ethereum Capital Gains Tax Calculator in Missouri

How the IRS Treats Cryptocurrency

The IRS issued guidance in 2014 (Notice 2014-21) classifying cryptocurrency as property, not currency. This single classification has sweeping consequences: every time you dispose of crypto, you must calculate gain or loss and report it to the IRS—just like selling stock.

Taxable events (trigger a gain/loss calculation):

• Selling crypto for USD or fiat currency
• Trading one cryptocurrency for another (BTC → ETH is a taxable exchange)
• Spending crypto to purchase goods or services
• Receiving crypto as payment for services rendered
• Earning staking rewards, mining rewards, or yield farming income

• Buying crypto with fiat (no gain/loss yet—this sets your cost basis)
• Transferring crypto between your own wallets
• Receiving crypto as a gift (the recipient inherits the donor's basis)
• Donating crypto to a qualified charity (may be a deductible charitable contribution)

📊 Short-Term vs Long-Term Rates

As with all capital assets, the holding period determines which rate applies.

Short-Term Capital Gains (held ≤ 365 days) Taxed at your ordinary income rate—10% to 37% for 2026. Active traders moving in and out of positions frequently will face the highest rates.

Long-Term Capital Gains (held > 365 days) Taxed at 0%, 15%, or 20% depending on your total taxable income:

| 2026 Long-Term Rate | Single Filer Income | Married Filing Jointly | |---|---|---| | 0% | Up to $47,025 | Up to $94,050 | | 15% | $47,026 – $518,900 | $94,051 – $583,750 | | 20% | Over $518,900 | Over $583,750 |

High earners also owe the 3.8% Net Investment Income Tax (NIIT) on crypto gains if their MAGI exceeds $200,000 (single) or $250,000 (married jointly), pushing the effective long-term rate to 23.8%.

🧮 Cost Basis Methods: FIFO, HIFO, and Specific ID

When you've purchased the same cryptocurrency multiple times at different prices, you must choose an accounting method to determine which coins were "sold":

FIFO (First In, First Out) The default method. The oldest coins you purchased are considered sold first. In a bull market where early purchases have the lowest cost basis, FIFO produces the largest gains (and highest taxes).

HIFO (Highest In, First Out) Sell your highest-cost-basis coins first, minimizing the gain on each sale. HIFO consistently produces the lowest taxable gains and is IRS-permissible with proper records.

Specific Identification You designate exactly which lot of coins you're selling. Requires detailed records but allows maximum flexibility to choose high-basis coins.

> Important: The IRS requires you to apply your chosen method consistently within a tax year. Switching mid-year is not permitted without justification.

DeFi, Staking, and NFTs: Emerging Tax Issues

Staking Rewards The IRS ruled in Revenue Ruling 2023-14 that staking rewards are taxable as ordinary income when received, valued at fair market value on the date of receipt. This income establishes your cost basis for future gains/loss calculations when you sell the staked tokens.

DeFi Liquidity Pools Depositing assets into a liquidity pool and receiving LP tokens may be a taxable exchange event. Each swap on a DEX (like Uniswap) is a separate taxable crypto-to-crypto trade.

NFTs NFTs are treated as capital assets (or collectibles if the underlying asset qualifies). Gains on NFT sales are taxable; collectible-category NFTs may face the 28% collectibles tax rate rather than the standard 0/15/20% rates.

Mining Income Crypto received from mining is taxable as ordinary income when mined, at the fair market value on the date of receipt. If you sell mined coins later, the subsequent gain/loss is a capital gain/loss with your mining-day income value as the cost basis.

Tax-Loss Harvesting Without the Wash Sale Trap

Tax-loss harvesting—selling losing positions to offset gains—is highly effective for crypto portfolios. The key advantage over stocks: the wash sale rule does not currently apply to cryptocurrency.

For stocks, you cannot repurchase the same security within 30 days of a loss sale. For crypto, the IRS has not extended this rule, meaning you can: 1. Sell BTC at a loss on December 28 2. Immediately repurchase BTC on December 28 3. Recognize the full tax loss while maintaining your position

This creates a legitimate year-end strategy for active crypto holders. *Note: Congress has proposed extending wash sale rules to crypto—monitor legislative developments.*

Annual loss limits:** Capital losses offset gains dollar-for-dollar. Excess losses can offset up to **$3,000 of ordinary income per year; remainder carries forward indefinitely.

How to Report Crypto Taxes

Form 8949: Report every individual crypto transaction (date acquired, date sold, proceeds, cost basis, gain/loss).

Schedule D: Summarizes all Form 8949 entries into total short-term and long-term gains/losses.

Schedule 1 / Schedule C: Ordinary income from mining, staking, or employment compensation in crypto.

FinCEN 114 (FBAR): If you hold crypto on foreign exchanges with balances exceeding $10,000 at any point in the year, FBAR filing may be required.

Record-Keeping**: Maintain complete transaction history for **at least 3 years after filing (7 years if there's potential for material underreporting). Use crypto tax software (Koinly, CoinTracker, TaxBit) to aggregate across exchanges and generate pre-filled Form 8949.

Practical Planning Strategies

Hold for 1+ year whenever possible. The rate difference between short-term (37%) and long-term (20%) is the largest gap in the US tax code for investment assets.

Harvest losses strategically in Q4. Review your portfolio in October–November. Realize losses to offset gains taken earlier in the year. You can immediately repurchase (no wash sale rule for crypto).

Donate appreciated crypto to charity. If you donate long-term-appreciated crypto directly to a 501(c)(3) charity, you avoid capital gains tax *and* receive a deduction for the full fair market value.

Use tax-advantaged accounts where available. Some crypto ETFs (like spot Bitcoin ETFs) can now be held in IRAs and 401(k)s, allowing gains to compound tax-deferred or tax-free (Roth).
