There’s no denying it—2025 has been a banner year for cryptocurrency investors. With Bitcoin hitting all-time highs and renewed enthusiasm across digital assets, many investors are feeling pretty good about their portfolios. The good news? Profits alone don’t create taxes. You generally trigger taxes only when you sell crypto or use it to buy something.
The even better news is that there are still several smart, legal strategies you can use before year-end to reduce your 2025 tax bill—and potentially your future crypto taxes as well. Let’s break them down in plain English.
Strategy #1: Lock In Gains on Your Terms (Tax-Gain Harvesting). If you expect your income to rise next year—or you believe your crypto will continue to appreciate—you may want to consider tax-gain harvesting. This strategy involves selling appreciated crypto now, paying tax on the gain at today’s rates, and then immediately buying it back. Because doing so resets (or “steps up”) your tax basis to the current value.
That means future gains are taxed on a smaller spread. Why timing matters. Crypto held more than one year qualifies for long-term capital gains rates (15% for many taxpayers). Crypto held less than one year is taxed at ordinary income rates, which are often much higher.
If your gains are long-term and you expect even higher income—or higher prices—down the road, harvesting gains now can be a smart move. If your gains are short-term, waiting may make more sense.
Strategy #2: Harvest Crypto Losses. Even in strong markets, not every crypto investment is a winner. If you have crypto that’s worth less than what you paid for it, those losses can work in your favor. By selling crypto at a loss before year-end, you can: Offset capital gains from other crypto or investments; Offset up to $3,000 of ordinary income; Carry unused losses forward to future years.
Short-term losses first offset short-term gains. Long-term losses first offset long-term gains. Anything left over can be applied across categories. A unique crypto advantage: Unlike stocks, cryptocurrency is treated as property, not a security.
That means the wash-sale rules do not apply (at least for now). Translation: You can sell crypto at a loss, realize the deduction, and buy it back immediately—no 30-day waiting period required.
Strategy #3: Donate Crypto and Skip the Capital Gains Tax. If you’re charitably inclined and you itemize deductions, donating appreciated crypto can be one of the most tax-efficient moves available.
When you donate crypto held more than one year to a qualified 501(c)(3) charity, you avoid capital gains tax entirely, and you receive a charitable deduction for the fair market value of the crypto on the date of donation.
That’s a powerful one-two punch. Crypto can be donated directly to charities that accept it, or through a donor-advised fund (DAF), allowing you to take the deduction now and distribute to charities later.
Important reminders: You must itemize to get the deduction. Donations of appreciated crypto are generally limited to 30% of AGI. Donations over $5,000 require a qualified appraisal and IRS Form 8283.
Strategy #4: Gift Crypto to Family Members. Crypto can also be a smart gifting tool. For 2025, you can gift up to $19,000 per recipient ($38,000 for married couples) without triggering gift tax or filing a gift tax return.
Why this works: You don’t pay capital gains tax on the gift. The recipient doesn’t report income until they sell. Gifts under the annual exclusion require no IRS reporting. Just remember: the recipient inherits your original cost basis, so future taxes depend on when and how they sell.
Pro tip: Always document crypto gifts with a simple letter outlining acquisition date, basis, fair market value, and confirmation that it was a gift.
Strategy #5: Buy Crypto Inside a Retirement Account. If you’re thinking long-term, consider purchasing crypto inside a retirement account. Self-Directed IRA (SDIRA) allows investments in crypto (unlike most traditional custodians). Traditional SDIRA: Contributions may be deductible; taxes paid at withdrawal.
Roth SDIRA: No deduction upfront, but qualified withdrawals are tax-freen. You cannot contribute existing crypto—you must fund the account with cash or rollovers. Any buying and selling inside the IRA does not trigger current taxes.
Self-Directed Solo 401(k). If you’re self-employed (with no employees other than a spouse), a solo 401(k) offers much higher contribution limits than an IRA. For 2025, total contributions can reach up to $70,000 (under age 50), up to $77,500 (ages 50–59 or 64+), or up to $81,250 (ages 60–63). The plan must be established by December 31, 2025, so this is one strategy that truly is year-end sensitive.
Crypto taxes don’t have to be scary—but they do require planning. The best strategy is rarely “do nothing and hope for the best.” As always, the smartest move is coordinating these strategies with your overall tax picture—before the year closes and the window slams shut.
