The date is November $15,2020.$ You are the new controller for Engineered Solutions. The company treasurer, Randy Patey, believes that as a result of pending legislation, the currently enacted $40\%$ income tax rate may be decreased for $2021$ to $25\%$ and is uncertain which tax rate to apply in determining deferred taxes for $2020.$ Patey also is uncertain which temporary differences should be included in that determination and has solicited your help. Your accounting group provided you the following information.

Two items are relevant to the decisions. One is the $$50,000$ insurance premium the company pays annually for the CEO's life insurance policy, for which the company is the beneficiary. The second is that Engineered Solutions purchased a building on January $1,2019,$ for $$6,000,000.$ The building's estimated useful life is $30$ years from the date of purchase, with no salvage value. Depreciation is computed using the straight$-$line method for financial reporting purposes and the MACRS method for tax purposes. As a result, the building's tax basis is $$5,200,000$ at December $31,2020.$

$2.$ How do you differentiate temporary differences and permanent differences?
