Things You'll Need:
- IRS Tax Form 1098 (if using second home tax deduction)
- Proof of business expenses (corporate and business boats and yachts)
-
Step 1
Identify the interior boat requirements. To qualify as a second home tax deduction, your boat must have the following: sleeping quarters (this can be as simple as a platform with a mattress), bathroom facilities (at least a port-a-potty), cooking facilities and a sink.
-
Step 2
Recognize your time requirements. You must stay overnight on your boat at least a total of two weeks during the year to use it as a tax deduction. The IRS states that you must provide "proof" that you stay overnight for a total of two weeks, but is vague about what type of "proof" is needed.
-
Step 3
Use "Accelerated Depreciation" as a tax deduction for your boat. If you purchase a boat through a company you own, you can deduct half of the total amount you paid for the boat as an accelerated depreciation loss.
-
Step 4
Purchase a corporate yacht. You are allowed to deduct all of the expenses that pertain to owning and operating the yacht if you own a corporate yacht. You must, however, provide proof to the IRS that the yacht was used for business purposes.
