If you’ve built serious wealth in crypto, whether from early entries, active trading, or running validators, you’re facing a tax situation your regular CPA probably isn’t equipped for. The rules just tightened, and the tools that work now won’t work the same way in 2026. Here’s what that actually means and what to do about it.
Part of our guide: Family Office.
The Reporting Shift You Need to Plan Around
Starting with transactions from January 1, 2025, brokers, including exchanges, hosted wallet providers, and payment processors, must report customer sales on a new IRS form, Form 1099-DA. For 2025, they only have to report gross proceeds, not cost basis. That gap matters: the IRS will see large sale amounts without seeing what you actually paid, which means accounts showing losses or small gains on paper are more likely to get flagged. Keep auditable records of your cost basis for every lot, because you may need to defend it. Mandatory cost basis reporting kicks in on January 1, 2026, and internationally, the OECD’s Crypto-Asset Reporting Framework is closing the door on offshore accounts staying invisible.
2025 Is the Last Year for Flexible Cost Basis Accounting
Right now you can choose how to identify which lots you’re selling: FIFO, LIFO, Highest-In-First-Out (HIFO), or Specific Identification. HIFO lets you match sales against your highest-cost lots, which minimizes taxable gains or maximizes losses you can claim. Starting January 1, 2026, brokers will be required to default to FIFO for reporting, which is the least tax-efficient method in a portfolio that’s appreciated, since it sells your oldest, cheapest lots first. If tax-loss harvesting or rebalancing makes sense for your portfolio, 2025 is the year to do it under the more favorable methods. After that, you’ll need to actively use Specific Identification to override the FIFO default.
Staking, DeFi, and the Wash Sale Gap
Staking and DeFi yield are taxed as ordinary income at the fair market value when you gain “dominion and control,” meaning you can actually move or spend the coins. If rewards are locked, tax is deferred until they unlock. That fair market value becomes your cost basis going forward, so any appreciation after that point is taxed at the lower long-term capital gains rate once you’ve held it a year.
Separately, the IRS wash sale rule doesn’t currently apply to crypto, because crypto is classified as property rather than a security. That technically lets you sell at a loss and immediately rebuy the same token to lock in the deduction. Congress has proposed closing this loophole, so the more conservative approach if you want the strategy to hold up long term is to wait the traditional 30 days before repurchasing, or rotate into a correlated but non-identical asset instead.
Entity Structure: Wyoming LLC as a Holding Company
A Wyoming single-member LLC set up as a holding company, not a trading LLC, preserves long-term capital gains treatment, capped at 20% federally, instead of ordinary income rates on short-term gains, up to 37%. It also gives you charging order protection: if someone sues you personally, they generally can’t force a sale of the LLC’s crypto, only collect against future distributions. Documentation matters here as much as the structure itself. The operating agreement needs to address digital assets specifically, listing wallet addresses, tickers, amounts, and dollar values at the time of transfer, notarized to establish your cost basis and holding period. Keep corporate minutes even for a single-member LLC; skipping that is exactly how a corporate veil gets pierced in a lawsuit.
Trusts and the Lifetime Exemption
For larger estates, an Intentionally Defective Grantor Trust (IDGT) lets you sell appreciating crypto into the trust in exchange for a promissory note, freezing the asset’s value in your estate while future appreciation accrues to your heirs outside your taxable estate. A Grantor Retained Annuity Trust (GRAT) works differently: you retain annuity payments for a term, and if the crypto appreciates faster than the IRS’s assumed rate, the excess passes to beneficiaries gift-tax free, without using your lifetime exemption.
The lifetime gift and estate exemption sits at $15 million per individual in 2026, and legislation enacted in 2025 repealed the scheduled cut and made that level permanent, so the deadline that once drove IDGT planning no longer exists. Separately, you can give $19,000 per recipient per year without touching that lifetime exemption at all, and gifting appreciated crypto during your life passes your cost basis to the recipient, while assets transferred at death get a step-up to fair market value instead.
Location and Compliance
Moving residency from a high-tax state like California to Texas, Wyoming, or Florida eliminates state income tax entirely, provided you establish genuine residency: more than 183 days a year, a local driver’s license, local bank accounts. Puerto Rico’s Act 60 goes further, taxing local income at 4% and capital gains accrued after residency at 0%, but it requires 183 or more days on the island, an annual charitable donation, and buying property within two years. Offshore asset protection trusts in places like the Cook Islands offer real protection from creditors but no U.S. tax benefit whatsoever; the IRS taxes worldwide income regardless of where the trust sits.
None of this works without documentation: Form 709 for gifts into trusts, Form 8997 annually for Opportunity Zone investments, and Form 8938 or eventual FBAR reporting for foreign-held crypto above the relevant thresholds. If you have undisclosed foreign holdings, the IRS’s Voluntary Disclosure Practice is worth discussing with a professional before the agency’s expanding data sources find it first.
Talk to a CPA and estate attorney who actually understand digital assets before implementing any of this. The structures aren’t new, but applying them correctly to crypto requires someone who’s done it before.
