Martha is single and self-employed realtor and is 42 years old. Her rental income is $60,000 on residential building and $80,000 on her office building. She pays $750 for health insurance.

Martha drove her personal car 16,600 miles for business purposes and incurred $240 in parking fees, $310 in highway tolls, and $350 for automobile insurance premiums. Compute Martha's deduction for automobile expenses on her current year tax return, assuming all of the above expenses are valid (standard mileage allowance method ).

Martha, a realtor, paid $5,000 to Walton Way Apartments, Inc. as a referral fee for referring customers to her. One of her competitors complained to the local Realtor's Board that these payments were "kickbacks," deemed unethical conduct by the Board. The Board agreed with her competitor, but noted that the payments were not illegal under federal law, and local laws against such fees have not been enforced for several years. Thus, the Board indicated that it would write a letter to Martha explaining its view that the payments are unethical, but that there was really little else that either it or the competitor could do. Martha countered to the Board that she would prefer not to make the payments, but that such payments are a common practice among realtors in the city, and that her business would suffer if she did not make them as well. (Can Martha deduct the payments on her federal income tax return?)
