Cryptocurrency & Digital Asset Tax Planning for Wealthy Families

At $2M–$20M in net worth, a meaningful crypto allocation is increasingly common — and the tax rules are substantially different from traditional investments. The IRS classifies crypto as property, not a security: that single fact drives every planning opportunity, from no-wash-sale tax-loss harvesting to estate step-up at death, and every pitfall, from staking rewards being taxed as ordinary income to Bitcoin ETF shares losing the wash-sale exemption. A generalist advisor often doesn't know these nuances. Here's what the $2M–$20M crypto holder needs to understand for 2026.

How cryptocurrency is taxed: the baseline

Since IRS Notice 2014-21, the IRS has classified cryptocurrency as property — not currency and not a security. That means capital gains treatment for appreciation, with rates that depend heavily on how long you've held the asset:¹

For households earning $2M or more, the 20% long-term capital gains rate applies (the 15%/20% threshold is well below your income level). The 3.8% Net Investment Income Tax under IRC § 1411 applies above $250,000 MAGI for married filing jointly — and that threshold is not inflation-adjusted, making it permanently relevant at your wealth tier. The combined result: a 17-percentage-point spread between the 23.8% long-term rate and the 40.8% short-term rate based solely on holding period.

The no-wash-sale advantage: tax-loss harvesting with no 30-day waiting period

For stocks and mutual funds, IRC § 1091 disallows a loss if you repurchase a "substantially identical" security within 30 days before or after the sale — the wash sale rule. This restriction does not apply to cryptocurrency.²

Because crypto is property (not a stock or security), you can:

1. Sell Bitcoin at a loss to realize the tax deduction
2. Immediately repurchase the same amount of Bitcoin on the same day
3. Claim the capital loss — offsetting gains elsewhere in your taxable portfolio — with no disallowance

For a $2M–$20M investor with $300,000 in unrealized crypto losses, harvesting offsets $300,000 of other gains — saving approximately $71,400 at the long-term rate (23.8%) or $122,400 at the short-term rate (40.8%). You maintain full market exposure throughout.

Cost basis methods in 2026: HIFO, per-wallet tracking, and the new 1099-DA

The IRS allows two approaches to identifying which crypto lots you've sold: First-In-First-Out (FIFO) and Specific Identification. FIFO is the default if you don't make an election. Specific Identification lets you select which lots — enabling a Highest-In-First-Out (HIFO) approach that sells your highest-cost lots first, minimizing taxable gain on each transaction.³

Three 2026 rule changes affect basis tracking for this year's returns:

• Per-wallet basis tracking is required. Revenue Procedure 2024-28 ended the "universal wallet" method where investors pooled all Bitcoin basis across exchanges. As of January 1, 2025, you must track cost basis within each wallet or exchange account separately. If you moved crypto between exchanges without tracking per-wallet records, Rev. Proc. 2024-28 provided a safe harbor for allocating pre-2025 basis — but that transition window closed January 1, 2025.⁴
• Specific Identification (HIFO) still works — with documentation. Notice 2026-20 (March 2026) extended transitional relief through December 31, 2026: you can use Specific Identification without prior broker notification, but you must maintain contemporaneous records of which lots you selected before each disposal. "Contemporaneous" means at the time of the transaction, not reconstructed later.³
• Form 1099-DA reporting starts with 2026 transactions. Centralized exchanges must report capital gains, losses, and cost basis to the IRS for 2026 tax year transactions (forms issued in early 2027). If you use HIFO via Specific Identification but the exchange's 1099-DA reports on a FIFO basis, the discrepancy must be reconciled on your return with your own records. Without documentation, the IRS defaults to FIFO — often the higher-gain option.¹

Staking rewards, DeFi yield, and lending income: ordinary income at receipt

Revenue Ruling 2023-14 established that staking rewards are gross income — ordinary income — at fair market value when you gain dominion and control over them, regardless of whether you've sold them.⁵ The same principle extends to DeFi lending interest and crypto savings account interest.

For a $2M–$20M earner in the 37% bracket and above the NIIT threshold, staking rewards hitting your wallet are taxed at 40.8% in the year received. The silver lining: your cost basis in those rewards equals the fair market value at receipt, so subsequent appreciation held longer than one year qualifies for the 23.8% long-term rate when you sell.

Donating appreciated crypto: the highest-impact charitable move

Donating cryptocurrency directly to a Donor Advised Fund eliminates the capital gains tax entirely and generates a full fair-market-value charitable deduction. For appreciated crypto, this is almost always better than selling and donating cash:

Note that 2026 OBBBA rules apply: the 0.5% AGI floor and 35% deduction rate cap affect how much DAF bunching saves in a given year. See the charitable giving guide for the full DAF bunching and private-foundation analysis.

Estate planning for crypto: stepped-up basis and the custody problem

Cryptocurrency receives a stepped-up cost basis at death under IRC § 1014, just like stocks and real estate. A $2M Bitcoin position with a $200,000 original cost basis means a $1.8M embedded gain that disappears entirely for income tax purposes when the holder dies — the heir inherits at the $2M date-of-death value. This makes high-embedded-gain crypto one of the best assets to hold through death rather than sell during lifetime.

However, digital assets create estate planning challenges that don't exist with traditional brokerage accounts:

• Private key access. If your executor cannot access your wallet's private keys or seed phrase, the crypto is permanently unrecoverable — no court order can recover it. Seed phrases and private keys must be securely documented in your estate plan, stored in a form your executor can access (encrypted storage with documented access, or a physical copy in a fireproof safe with instructions to your attorney or trustee).
• Multi-signature wallets. For large holdings, a multi-sig structure (e.g., 2-of-3 keys required) distributes key custody among you, your attorney, and your executor — eliminating a single point of loss or theft.
• Estate attorney coordination. Your estate attorney must know what you hold, where it's custodied, and how keys are controlled. Many practitioners still have limited digital asset experience; verify the attorney understands the technical requirements before assuming your estate plan covers it.
• GRAT opportunity for high-volatility assets. Crypto's high volatility and growth potential makes it suitable for a Grantor Retained Annuity Trust — if the position appreciates above the § 7520 hurdle rate (currently 5.00%), the excess transfers to heirs tax-free without touching the $15M lifetime exemption. See the trust strategies guide for GRAT mechanics and the interactive calculator.

Working with a fee-only advisor on crypto tax planning

Crypto tax planning at the $2M–$20M level isn't a one-time filing exercise — it requires ongoing coordination across your portfolio, tax situation, and estate plan. A fee-only advisor with digital asset experience coordinates:

• Portfolio-level gain/loss netting. Timing crypto disposals to offset realized gains across taxable accounts — coordinating with equity tax-loss harvesting, business income events, Roth conversion planning, and QOZ investments in the same tax year.
• Basis documentation and per-wallet tracking. Ensuring your cost basis records comply with Rev. Proc. 2024-28 per-wallet requirements before exchanges issue 1099-DAs that default to FIFO.
• DAF donation sequencing. Identifying which appreciated positions — crypto or otherwise — produce the largest after-tax charitable impact when donated directly versus sold and donated as cash, coordinated with the bunching strategy for the 35% deduction cap.
• Estate integration. Ensuring your estate plan addresses private key access, executor authority over digital assets, and whether high-basis positions should be sold now or held for step-up.
• Roth and bracket coordination. Modeling whether low-basis crypto should be held for estate step-up, donated to a DAF, or sold and immediately repurchased in a TLH year — and how each interacts with Roth conversion windows and IRMAA bracket management.

1. IRS.gov — Digital Assets (Official IRS Guidance Hub). The IRS classifies digital assets as property under Notice 2014-21 (2014-21 I.R.B. 938). Capital gains treatment applies: dispositions after more than one year of holding qualify for long-term capital gains rates (20% for high-income filers in 2026); dispositions within one year are taxed as ordinary income (up to 37%). The 3.8% Net Investment Income Tax (IRC § 1411) applies to net investment income — including short-term and long-term capital gains from digital assets — for filers above $250,000 MAGI (MFJ). Starting with 2026 tax year transactions, centralized exchanges must issue Form 1099-DA reporting capital gains, losses, and cost basis to the IRS, pursuant to final broker reporting regulations issued July 2024. Charitable donations of appreciated crypto to a qualified organization (including a DAF) trigger no capital gains recognition event and generate a FMV deduction under IRC § 170.
2. CoinLedger — Crypto Wash Sale Rule: Tax Savings 2026. IRC § 1091 (the wash sale rule) disallows losses on the sale of "stock and securities" if substantially identical stock or securities are repurchased within 30 days before or after the sale. The IRS classifies cryptocurrency as property (IRS Notice 2014-21), not stock or a security — therefore § 1091 does not apply to spot cryptocurrency. An investor can sell Bitcoin at a loss and repurchase immediately without disallowance. Critical exception: spot Bitcoin ETF shares and other crypto ETF shares are investment company securities; the wash sale rule applies to ETF transactions. Legislative proposals to extend § 1091 to digital assets have been introduced in Congress but none has been enacted through 2026. Future legislation could change this.
3. CoinLedger — Rev. Proc. 2024-28: IRS New Crypto Cost Basis Rules. Revenue Procedure 2024-28 ended the universal wallet basis pooling method and requires digital asset cost basis to be tracked on a per-wallet and per-account basis effective January 1, 2025. The IRS permits two cost basis identification methods: First-In-First-Out (FIFO, the default) and Specific Identification (allowing HIFO — Highest-In-First-Out — lot selection). Specific Identification minimizes taxable gains by selling highest-cost lots first but requires contemporaneous documentation of each lot selected at the time of each disposal. Notice 2026-20 (March 2026) extended transitional relief through December 31, 2026, permitting Specific Identification without prior broker notification if the taxpayer maintains their own lot-selection records.
4. IRS.gov — Revenue Procedure 2024-28 (Official Text, IRS.gov). Rev. Proc. 2024-28 provides transitional guidance for taxpayers to allocate remaining cost basis to digital assets held within each separate wallet or account as of January 1, 2025 — the effective date of the per-wallet tracking requirement under the final digital asset broker reporting regulations. The procedure allows taxpayers to use any reasonable allocation method to assign unattached basis to remaining digital asset units, under a safe harbor, before December 31, 2024. Taxpayers who did not complete basis allocation under Rev. Proc. 2024-28 by January 1, 2025 must track basis going forward on a per-wallet basis from the earliest records available.
5. IRS.gov — Revenue Ruling 2023-14 (Official IRS Text). Rev. Rul. 2023-14, published in IRB 2023-33 (August 14, 2023), holds that a cash-method taxpayer who receives validation rewards from staking cryptocurrency must include the fair market value of those rewards in gross income for the taxable year in which the taxpayer gains dominion and control over the rewards. The ruling covers both direct staking and staking through a centralized cryptocurrency exchange. The cost basis of staking rewards is set at the FMV at the time of receipt; subsequent appreciation held more than one year qualifies for long-term capital gains rates upon disposition. The Jarrett v. United States litigation (W.D. Tenn.) challenging this position has a bench trial scheduled for September 29, 2026 if cross-motions for summary judgment do not resolve the case.
