Buying a Boat Through Your Business: Why the IRS Blocks Most Yacht Write-Offs

The IRS entertainment guidance puts a yacht in a specific category and treats every category member the same. The rule reads: "Entertainment facilities. Generally, you can't deduct any expense for the use of an entertainment facility. This includes expenses for depreciation and operating costs such as rent, utilities, maintenance, and protection. An entertainment facility is any property you own, rent, or use for entertainment. Examples include a yacht, hunting lodge, fishing camp, swimming pool, tennis court, bowling alley, car, airplane, apartment, hotel suite, or home in a vacation resort."^[2]

The reach of the rule is what people miss. It is not limited to boat trips. Depreciation, fuel, dockage, insurance, cleaning, maintenance, and captain wages that trace to entertainment use of the yacht all sit inside the same deny-all category.^[2] A South Florida owner who buys a boat inside an LLC to host clients has not created a deductible expense, and the LLC wrapper does nothing to change that outcome. For the small business side of the picture our small business accounting work is where these classification calls get made before the boat is ever bought.

Two rules stack for a boat used to host clients, and both cut the same way. The older rule denies deductions tied to an entertainment facility. The newer rule, effective for amounts paid or incurred after December 2017, denies deductions for entertainment expenses generally: "You can no longer take a deduction for any expense related to activities generally considered entertainment, amusement, or recreation. You can continue to deduct 50% of the cost of business meals if you (or your employee) are present and the food or beverages aren't considered lavish or extravagant."^[3]

A yacht outing sits inside the definition. The IRS entertainment guidance identifies yacht outings as an example of entertainment.^[4] A separately stated meal on the boat may qualify for the 50% business meal rule when the standard tests are met, but the boat time around it does not.^[3] The right frame for a business owner considering a yacht is that the default is no deduction, and the exceptions are narrow and evidenced rather than assumed.

A different rule set applies when the boat is genuinely a business asset rather than a floating conference room. The IRS depreciation guidance defines listed property to include "cars, business aircraft, and other property used for transportation, property used for entertainment, and certain computers."^[5] A vessel used to transport paying passengers, to carry commercial catch, to move cargo, or to run a chartered fishing operation lands in the transportation half of that definition, not the entertainment half.

The classification is what matters, and the classification is driven by what the boat actually does. A boat with paying passengers on a chartered trip, a fishing guide running clients up the coast, or a diving instructor taking a group to a reef, all point at a trade or business separate from the owner's entertainment. A boat that mostly sits at a private slip and occasionally hosts prospects does not. For the return that reflects either picture see our business tax return preparation page, and for the underlying documentation see small business accounting.

Once a boat is listed property, the depreciation regime tightens. The listed property rule is direct: "Business-use requirement. If the property is not used predominantly (more than 50%) for qualified business use, you cannot claim the section 179 deduction or a special depreciation allowance. For business aircraft, there is also a 25% test that must be met. In addition, you must figure any depreciation deduction under MACRS using the straight line method over the ADS recovery period."^[6]

Read the sentence twice, because it stacks three penalties on one failure. Falling below the 50% qualified business use line costs the immediate expensing of Section 179, costs the special depreciation allowance including the 100% bonus discussed later, and forces the remaining MACRS depreciation onto a slower straight line method over a longer ADS recovery period.^[6] A boat bought in a strong revenue year to soak up income delivers the opposite outcome when the business use share cannot be established later.

This is the trap. Entertainment use of listed property is treated as business use only to the extent the expense itself is deductible: "Entertainment use. Treat the use of listed property for entertainment, recreation, or amusement purposes as a business use only to the extent you can deduct expenses (other than interest and property tax expenses) due to its use as an ordinary and necessary business expense."^[9]

So the yacht outing that would have been counted as client entertaining does not count. Because the underlying entertainment expense is nondeductible, the corresponding hours on the water are not qualified business use for the 50% test either.^[9] That is why so many plans built around a we-take-clients-out-on-the-boat theory collapse at audit: the very hours the owner logged as business are the hours the rule strips out first, and once they are removed the boat rarely clears the 50% line.

For a boat that does clear the qualified business use bar, the recovery is straightforward. The IRS depreciation class table places vessels in the 10 year class: "10-year property. Vessels, barges, tugs, and similar water transportation equipment."^[10] That is the ordinary MACRS life.

The accelerated pieces sit on top. Section 179 lets a business elect to expense qualifying property up to a dollar cap: "For tax years beginning in 2025, the maximum section 179 expense deduction is $2,500,000."^[12] The 2026 figure is higher: "beginning in 2026, the maximum section 179 expense deduction is $2,560,000. This limit is reduced by the amount by which the cost of section 179 property placed in service during the tax year exceeds $4,090,000."^[11] On the bonus side, The IRS depreciation guidance restores full expensing for newer acquisitions: "100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025 (including long production period property and certain aircraft), and certain specified plants bearing fruits and nuts planted or grafted after January 19, 2025."^[7] A working vessel that clears the listed property tests can, in principle, reach immediate expensing. See our the OBBB bonus depreciation and Section 179 changes guide for the underlying regime that governs both figures.

Records are load bearing for listed property. The listed property rule is unambiguous: "You cannot take any depreciation or section 179 deduction for the use of listed property unless you can prove your business/investment use with adequate records or with sufficient evidence to support your own statements."^[8]

Contemporaneous is doing all the work in that sentence. A boat log reconstructed after the notice arrives is exactly what the rule was written to reject. What the IRS wants across the year is a running record of who was on the boat, what the trip was for, how many hours it ran, what the fuel and slip costs were, and how each trip mapped to a paying customer or an internal business purpose. The professional services tax help side of our practice sees the reverse problem too, where a real business trip is not deducted because the logbook is missing.

The right question is not whether the boat can be depreciated, but which side of the entertainment line the boat will actually sit on for the whole year A boat with a paying trade behind it, contemporaneous records, and enough revenue to hold the more than 50% qualified business use share is a genuine listed property asset and is depreciable within the ordinary rules.^[5][6] A boat bought as a client entertainment vehicle is not, and no LLC name, no marketing story, and no year end tax move changes that.^[2]

A firm's job on a decision like this is to run the numbers both ways before the boat is bought, to name the substance the trade or business needs to have, to shape the logbook and books that survive a listed property audit, and to say plainly when the plan does not work. That is the kind of decision our advisory solutions handle, and it lives inside the broader professional services tax help context that pushes many owners toward this question in the first place.
