If you use your item of listed property 30% of the time to manage your investments and 60% of the time in your consumer research business, it is used predominantly for qualified business use. Your combined business/investment use for determining your depreciation deduction is 90%. Most income tax systems allow a tax deduction for recovery of the cost of assets used in a business or for the production of income. Where the assets are consumed currently, the cost may be deducted currently as an expense or treated as part of cost of goods sold. The cost of assets not currently consumed generally must be deferred and recovered over time, such as through depreciation.
