1. Isabel, a calendar-year taxpayer, uses the cash method of accounting for her sole proprietorship. In late December she received a $26,000 bill from her accountant for consulting services related to her small business. Isabel can pay the $26,000 bill anytime before January 30 of next year without penalty. Assume her marginal tax rate is 40 percent this year and next year, and that she can earn an after-tax rate of return of 10 percent on her investments.

1-a. What is the after-tax cost if Isabel pays the $26,000 bill in January?

2. Daniel is considering selling two stocks that have not fared well over recent years. A friend recently informed Daniel that one of his stocks has a special designation, which allows him to treat a loss up to $30,000 on this stock as an ordinary loss rather than the typical capital loss. Daniel figures that he has a loss of $36,000 on each stock. If Daniel%u2019s marginal tax rate is 35 percent and he has $72,000 of other capital gains (taxed at 15 percent), what is the tax savings from the special tax treatment?
