The short answer: donate your yacht to a US 501(c)(3) charity that makes significant intervening use of the vessel — as The International SeaKeepers Society does, deploying donated yachts as ocean-science platforms — and you can generally deduct the independently appraised fair market value. If the charity simply resells the boat, the IRS limits your deduction to the gross sale proceeds. That single distinction is worth hundreds of thousands of dollars on a serious vessel, and it is the reason the choice of charity matters more than anything else in the transaction.
I facilitate yacht donations to SeaKeepers as an independent facilitator, at no fee to the donor. What follows is how the deduction actually works — the rule that decides the number, the arithmetic against a private sale, and the paperwork that protects the deduction if the IRS ever asks.
Since 2005, the IRS has applied a two-track rule to donated vehicles, boats, and aircraft. If the charity sells the vessel without meaningful use, your deduction is capped at whatever the boat fetched at auction — usually a liquidation price. If the charity makes significant intervening use of the vessel, or materially improves it, you may deduct fair market value as established by a qualified independent appraisal.
Most boat-donation programs are resale operations: the boat goes to auction, and the donor’s deduction shrinks to the hammer price. SeaKeepers is the exception that makes the structure work.
Founded in 1998, SeaKeepers is a functioning ocean-science organisation — not a reseller with non-profit status. It places instruments aboard vessels and deploys them in active research across more than 50 countries. The vessel goes to work, and the deduction is defended at appraised fair market value. The full process, from qualification to transfer, is laid out on our yacht donation page.
For an owner in a high-income year, in the top federal bracket, a $3 million fair-market-value deduction is worth on the order of $1.1 million in federal tax alone — with no commission, no months of showings, and no capital-gains recognition on an appreciated hull. A sale sometimes wins the arithmetic; when it does, we say so. That comparison is run with your tax counsel before the engagement letter is signed.
We assemble this package on every donation and coordinate directly with your tax attorney. It is the unglamorous half of the transaction, and it is where the deduction is won or lost.
Only if the receiving 501(c)(3) makes significant intervening use of the vessel or materially improves it. If the charity sells the boat, your deduction is limited to the gross sale proceeds. SeaKeepers’ ocean-science deployment is precisely the significant-use case the rule contemplates.
Roughly your marginal tax rate multiplied by the appraised value, subject to the 30%-of-AGI annual limit for appreciated property, with a five-year carry-forward for the balance. A top-bracket donor with a $3 million vessel is looking at seven figures of federal tax value.
Yes — a qualified appraisal for anything above $5,000, dated within 60 days of the donation. The appraiser’s fee is the only direct cost the donor bears in our process.
Nothing. Xplorer Yachts is compensated by SeaKeepers, not by the donor, and the structure is disclosed in writing. The initial qualification call is free, and if your vessel is unlikely to qualify we tell you immediately.
Offshore-capable yachts of roughly 60 feet and up, in operational seagoing condition, able to host science crew and instrumentation. Motor, sail, and expedition vessels are all eligible in principle.
The deduction described here is a US federal benefit for taxpayers who itemise. Non-US owners may have equivalent structures at home, or non-tax reasons to donate; we can refer maritime tax specialists in the relevant jurisdiction.
Qualification is one short conversation at no charge, and we will tell you whether the donation pathway beats a sale for your position. The full process is on our yacht donation page, and SeaKeepers’ science programme at yachtdonations.net.
