Doug Jones timely submitted his 2017 tax return and elected married filing jointly status with his wife Darlene. Doug and Darlene did not request an extension for their 2017 tax return. Doug and Darlene owed and paid the IRS $124,000 for their 2017 tax year. Two years later, Doug (Now divorced) would like to amend his return and claim married filing separate status. By changing his filing status, Doug wants a refund for an overpayment for the tax year 2017 (he paid more tax in the original joint return than he owed on a separate return). Explain why Doug can or cannot do this.

Mr. smith recently faced a choice between being (a) an economics profes-sor, which pays $60,000/yr, or (b) a safari leader, which pays $50,000/yr. after careful deliberation, smith took the safari job, but it was a close call. "for a dollar more," he said, "i'd have gone the other way."now smith's brother-in-law approaches him with a business proposition. the terms are as follows: - smith must resign his safari job to work full-time in his brother-in-law's business.- smith must give his brother-in-law an interest-free loan of $100,000, which will be repaid in full if and when smith leaves the business. (smith currently has much more than $100,000 in the the business will pay smith a salary of $70,000/yr. he will receive no other payment from the business. the interest rate is 10 percent per year. apart from salary considerations, smith feels that working in the business would be just as enjoyable as being an economics professor. for simplicity, assume there is no uncertainty regarding either smith's salary in the proposed business or the security of his monetary investment in it. should smith join his brother-in-law and, if so, how small would smith's salary from the business have to be to make it not worthwhile for him to join? if not, how large would smith's salary from the business have to be to make it worthwhile for him to join?
