B$2)$ Lee Corp files its taxes on $12-31-15,$ with a current marginal tax rate of $30\%$ and an expected marginal tax rate for later years of $25\%.$ Due to a tax law passed near the end of $2015,$ Lee is uncertain about the deductibility of $$30,000$ worth of expenses. Lee chooses to file a return with $$700,000$ in pretax income, including that $$30,000$ expense deduction. Lee's CPA informs them the will not meet the standard of "more likely than not" regarding that deduction.

Please make any necessary entries in Lee's books regarding taxes for Dec $31,2015,$ as well as any. entries required after the IRS concludes that only $$8,000$ of the uncertain deduction is permitted $($deductible$).$
