In Year One, Dolly received $90,000 in salary and a $10,000 cash bonus from her employer. Dolly had no deduction items for Year One, and the tax rate appli- cable in Year One was 25 percent. In Year Two, Dolly's employer discovered that a computational error accidentally inflated the amount of Dolly's Year One bonus. Dolly learned that the Year One bonus should have been $4,000. In Year Two, she repaid the $6,000 overpayment to the employer. Dolly received $90,000 in salary in Year Two and, again, had no other deductions for the year.
