Donating Crypto? How to Calculate Profit, Deduction, and What You Actually Save

Donating cryptocurrency feels simple, but the maths behind the gift is where many donors leave money on the table. Unlike cash, a crypto donation involves two calculations: the profit built up in the coins, and the tax deduction you may claim.

Get either calculation wrong and you might overstate what the charity receives, assume an unusable deduction, or sell first and pay avoidable capital gains tax. This guide uses one Bitcoin example throughout. All prices and rates are illustrative, and the rules mainly reflect the United States system; other countries differ, so check the rules where you live.

Why Donating Crypto Is Not the Same as Donating Cash

With cash, the amount you give is the amount the charity receives. With appreciated crypto, three values matter: what you paid, what the coins are worth on donation day, and the gain between them. Donating directly to a qualified charity is often not treated as a sale, so you pay no capital gains tax on that gain — yet the charity receives the full value. Sell first, and you pay tax before the charity sees a cent.

Key takeaway: Donating appreciated crypto directly can let the charity receive the full value while you avoid capital gains tax on the profit.

Work Out Your Profit Before You Donate

Start with your cost basis: what you paid, including purchase fees. If you bought in several batches, identify which batch you are donating, as each has its own basis and gain.

Cost Basis, Fair Market Value, and Gain

Fair market value on the donation date, minus your cost basis, equals your unrealised gain. For Bitcoin, use the market price at donation, via an exchange price or CoinGecko's Bitcoin price page. Keep purchase receipts and a dated price record; large gifts may need a formal valuation and charity acknowledgement. See also crypto profit and taxes: what counts as a taxable event.

Worked Example: Donating Directly Versus Selling First

Assumptions: 0.5 BTC bought at $40,000 per coin, donated when Bitcoin is worth $82,726 per coin, a 20% capital gains rate, and a 22% marginal rate for the deduction. Cost basis is 0.5 × $40,000 = $20,000. Fair market value is 0.5 × $82,726 = $41,363. Gain is $41,363 − $20,000 = $21,363, so tax if sold first would be 20% × $21,363 = $4,272.60.

A direct donation delivers the full $41,363. Selling first leaves only $37,090.40 after the $4,272.60 tax bill. The direct route also gives a larger deduction, worth an extra $939.97 at 22%. Add the tax avoided, and the total extra benefit is $5,212.57. That advantage only exists because the coins appreciated; if they had fallen, selling first could let you claim a capital loss instead.

What the Deduction Is Actually Worth — and Common Mistakes

A deduction is not a refund, nor is it worth its face value. A $41,363 deduction saves $41,363 multiplied by your marginal rate — $9,099.86 at 22% here — and only if you can use it.

Itemising, Eligibility, and Limits

In the United States, deductions generally only help if you itemise rather than taking the standard deduction, and the recipient must be qualified. The IRS guidance on charitable contribution deductions covers eligibility and record-keeping. Assets held over a year are typically deductible at fair market value; shorter holds may be limited to cost basis. Annual limits may also defer part of the saving.

Key takeaway: A deduction is worth its face value multiplied by your marginal tax rate — and only if you itemise, give to a qualified charity, and stay within the annual limits.

Other mistakes shrink the saving. Donating without a paper trail makes the deduction hard to support. Donating the wrong batch also wastes value: if you bought in multiple tranches, as explained in how to calculate profit when you have bought crypto in multiple batches, the largest-gain batch usually maximises the tax avoided. A charity accepting crypto does not prove it is qualified, so confirm its status first. At a loss, or if you cannot itemise, selling first may be better.

Conclusion

Donating crypto well comes down to three numbers: cost basis, fair market value on donation day, and the gain between them. When that gain is positive and the recipient qualifies, donating directly usually beats selling first — here, by $5,212.57, with $4,272.60 more reaching the charity. When the gain is negative, or the deduction cannot be used, selling first may be smarter. Let the table decide, not instinct.
