Key Takeaways

• Crypto is taxable property—every sale, trade, or use triggers a reporting event.
• 1099-K forms from exchanges will only be issued if BOTH the $20,000 and 200 transaction thresholds are met in 2026.
• Business operators and miners must report income on Schedule C and pay self-employment taxes.
• Both federal and Iowa tax returns must include all crypto gains and losses.
• Accurate record-keeping is critical. IRS audits are data-driven and increasingly common for crypto holders.

Why Crypto Is Taxable in 2026

All Sioux City individuals or businesses who buy, sell, trade, or use cryptocurrencies (Bitcoin, Ethereum, stablecoins, NFTs, altcoins) in 2026 must track and report those activities on their taxes. The 2025 One Big Beautiful Bill Act (OBBBA) confirmed that IRS property tax rules apply to crypto with no special exemptions for digital assets used in business or for personal investment.

What Triggers Crypto Tax in Sioux City?

• Trading crypto for fiat (selling Bitcoin for USD)
• Trading crypto for another crypto (e.g., ETH → ADA)
• Spending crypto on goods/services (e.g., paying a contractor with Ethereum)
• Receiving crypto as payment, mining, staking rewards, airdrops
• Gifting or transferring crypto with gain or loss

Capital Gains and Form 8949

Short-Term vs Long-Term Gains

If you held crypto for over 1 year, profits are taxed as long-term capital gains (0/15/20% rates federally). Less than 1 year = short-term, taxed as regular income. Always review holding periods for each crypto disposal event.

Cost Basis Calculation Methods

Most exchanges use FIFO (first-in, first-out), but IRS also allows specific identification and average cost, provided you maintain meticulous records. Many business owners reduce taxable gains with specific ID, selling highest-cost assets first.

2026 Third-Party Reporting Thresholds

Even if you do NOT receive a 1099-K from Coinbase or similar, YOU must still report every taxable event. The IRS can compare your return against blockchain records and known exchange activity.

Crypto Mining as a Business: Deductions & Schedule C

• Electricity (major deduction—allocate only portion used for mining)
• Depreciation of hardware/software (Section 179 or straight-line)
• Internet, cooling, data center, and maintenance costs
• Professional/accounting/tax prep fees

Hobby miners can’t deduct expenses but must report income. See IRS Publication 587 for business vs hobby distinction.

Iowa State Tax Treatment

Iowa does not tax crypto differently than the federal government. File capital gains on Form 1040, which flows to your Iowa return (rates: 3.1%–6.0% in 2026). There are no extra Iowa-specific crypto tax forms.

Uncle Kam Success Story: Compliance in Action

“Jasmine,” a Sioux City entrepreneur, traded and staked crypto for her catering business. She failed to track cost bases and received a 1099-K for $29,000 in proceeds. Uncle Kam Tax Strategy recalculated her gains using Specific Identification, reducing her tax bill by $3,100 compared to FIFO alone. Deductions for mining hardware/electricity were applied per Schedule C. Jasmine’s next-year compliance costs dropped by 50% after systematizing records and quarterly downloads from exchanges.

Frequently Asked Questions

Do I owe tax just for holding crypto?

No, holding alone is not taxable. Only sales, swaps, spending, or receipt (mining, airdrops) trigger taxation.

Can I deduct crypto losses?

Yes, capital losses offset capital gains in any asset class. Excess (over $3,000 per year) rolls forward indefinitely.

Does receiving gifted or airdropped crypto trigger tax?

Airdrops/staking are income at market value on receipt. Gifts have their own basis rules—generally not income to the recipient, but be sure to track.

Deadline for 2026 crypto tax filing?

Federal and Iowa state: April 15, 2027. Extensions available with Form 4868 (federal), but payment is still due by April 15!

Will Uncle Kam help reduce my audit risk?

Absolutely. Our crypto tax strategy systems ensure record-keeping, cost basis tracking, and deductions are audit-proof and maximize tax savings for business owners and investors.

What documentation should I keep?

Export and save: exchange CSVs, blockchain explorer screenshots, wallet records, cost basis calculations, sales proceeds, Form 1099s, and Iowa/Federal tax filings for at least 7 years.

Can crypto losses offset gains from stocks or real estate?

Yes. Capital gains and losses from all investment types are netted together on your tax return—crypto, stocks, and property alike.

Is mining/staking income subject to self-employment tax?

Yes for Schedule C operators—self-employment tax applies to net business income. Hobby miners pay only income tax on rewards.
