Business finance deals have tax deductible aspects. To be eligible for commercial lending, the vessel being purchased must be primarily for use in the business; the business owner must have a current ABN; ID and will be requested to provide financial documentation. A range of commercial financial facilities are available to businesses each with varying tax deduction rulings. The most popular choice of lending for businesses is Chattel Mortgage. With this type of commercial lending the entire GST on the purchase of the vessel can be claimed on the next BAS after purchase; the interest and any fees are tax deductible; and the asset can be depreciated as a way of claiming a tax deduction by the business. This is done by the accountant when the end of year accounts and income tax return is prepared.
