Business entertainment deduction
Business entertainment on your own boat is no different from business entertainment anywhere else...it would be same as if you invited clients to dinner at your home (yes, you can deduct a dinner party at home if it's ONLY for business purposes, and not just inviting a client/friend to your wife's birthday party in an effort to make it a deductable expense). You can't deduct any portion of your home OR boat expenses, but you can deduct the actual out-of-pocket expenses for that occasion--food, drink, fuel, transient dock charges at a waterfront restaurant, etc--would be deductable, but only a portion of it...At the time I sold my company 5 years ago, only 50% of business entertainment restaurant receipts were deductable...and it may even be less than that now.Boat owners have been trying to find a way to get the gov't to pay for all or part of their boats for as long as people have owned boats. The only viable deduction is the "second home" (or primary residence if you live aboard) interest deduction on any mortage. There are ways to deduct more, but they're more hassle than they're worth. For instance, putting it into charter just means you also have to report the charter income. YOu prob'ly won't make as much as chartering will cost you, and SOME of the losses will be deductable...but not all. Besides, tax deductions don't come off your taxes, they only reduce your taxable income. A $1000 deduction doesn't save you $1,000 in taxes, it only reduces your taxable income by that much...resulting in an actual tax saving of less than $50, but additional work for your CPA that runs your bill to him up $200.
