IRS Crypto Ruling: What It Means for Your 2026 Capital Gains — Aug 27, 2026

What Changed

240 UK taxpayers reported crypto capital gains exceeding £1 million each during the 2024–2025 tax year, the first time HMRC published granular crypto profit data. Total crypto capital gains reported across 17,600 filers reached £1.87 billion, an average of £106,250 per filer. The top 1.4% of crypto gainers captured nearly 17% of total reported profits.

Metric	Figure	Context
Total filers reporting crypto gains	17,600	First year HMRC separated crypto from general capital gains
Total crypto capital gains reported	£1.87 billion	Up from undisclosed prior years
Filers with gains over £1 million	240	1.4% of all crypto filers
Average gain per filer	£106,250	Median likely far lower due to top-heavy distribution

The Numbers That Matter

US taxpayers holding crypto positions face a different rate structure, but the UK disclosure offers a benchmark for concentration risk and tax planning. A $2 million crypto position liquidated in 2026 triggers federal long-term capital gains tax at 20% plus 3.8% net investment income tax (NIIT) for joint filers over $250,000 in modified adjusted gross income. State tax adds another layer.

Holding Period	Federal Rate	NIIT	California Total	Texas Total
Under 1 year	37.0%	3.8%	54.1%	40.8%
Over 1 year	20.0%	3.8%	37.1%	23.8%
Qualified small business stock (over 5 years)	10.0%	0.0%	23.3%	10.0%
Loss harvesting offset	0.0%	0.0%	0.0%	0.0%

What This Means for Your Portfolio

A $1.5 million realized gain on Bitcoin held for 18 months costs $357,000 in federal tax (23.8% effective rate) for a California resident, or $525,150 after state tax (35.01% blended rate). The same gain on a position held under 12 months costs $811,500 total (54.1%). The 289-day difference in holding period saves $286,350 net.

Scenario Analysis

Position size determines whether tax-loss harvesting, installment sales, or charitable remainder trusts shift the outcome. Below are net proceeds after federal and California state tax on a long-term gain with no offsets.

Gross Gain	Federal Tax (23.8%)	CA State Tax (13.3%)	Net Proceeds	Effective Rate
$500,000	$119,000	$66,500	$314,500	37.1%
$1,000,000	$238,000	$133,000	$629,000	37.1%
$2,000,000	$476,000	$266,000	$1,258,000	37.1%

The UK data shows the top 240 filers averaged £5.42 million each in gains. A US equivalent ($6.8 million at current exchange rates) leaves $4.28 million after tax in California. For positions of this size, deferred sales trusts and opportunity zone reinvestment are strategies that can reduce the effective rate below 30% if set up before sale.

Tax Arbitrage Opportunities

Crypto remains one of the few asset classes where daily mark-to-market volatility permits same-day loss harvesting without triggering wash sale rules. IRS Notice 2014-21 treats crypto as property, not a security. You can sell Bitcoin at a loss and repurchase the same day without the 30-day wash sale restriction that applies to stocks.

Strategy	Mechanics	Tax Benefit on $1M Position	Execution Window
Tax-loss harvest and immediate repurchase	Sell at loss, rebuy same asset same day	$238,000 federal offset (if full loss)	Any trading day
Donate appreciated crypto directly	Transfer to 501(c)(3), avoid cap gains, deduct FMV	Up to $119,000 saved vs. selling first	Before Dec 31
Installment sale via GRAT	Defer gain recognition over 10 years	Reduces annual MAGI, avoids NIIT	Requires trust formation
Opportunity zone reinvestment	Defer gain until 2026, reduce basis by 10%	$23,800 basis step-up on $1M gain	180 days from sale

The UK's 17,600 filers represent 0.05% of the adult population. In the US, Chainalysis estimates 27 million adults hold crypto, but IRS reporting on Form 1040 remains inconsistent. If US concentration mirrors the UK, roughly 12,000 US taxpayers may be sitting on unrealized gains over $1 million each. That cohort has not yet shown up in aggregated IRS Statistics of Income data.

Frequently Asked Questions

Q: Does the wash sale rule apply to Bitcoin or Ethereum?
A: No. Crypto is treated as property under IRS Notice 2014-21, so you can sell and repurchase the same asset immediately without triggering the 30-day wash sale disallowance.

Q: What is the capital gains rate on crypto held for 13 months?
A: 20% federal long-term rate plus 3.8% NIIT for high earners, totaling 23.8% before state tax.

Q: Can I donate Bitcoin directly to a charity and avoid capital gains tax?
A: Yes. Donating appreciated crypto held over one year allows you to deduct fair market value and avoid capital gains tax on the appreciation.

Q: How much tax do I save by holding crypto for 366 days instead of 364 days?
A: On a $1 million gain in California, the difference is $170,000 in total tax (54.1% short-term rate = $541,000 in taxes; 37.1% long-term rate = $371,000 in taxes).
