Task: Underpayment of Estimated Taxes:
Julie, being self-employed, is required to make estimated payments of her tax liability for the year. Her tax liability for 2011 was $25,000, and her AGI was less than $150,000. For 2012, Julie ultimately determines that her income tax liability is $18,000. During the year, however, she made the following payments, totaling $13,000:
April 16, 2012: $4,500
June 15, 2012: 2,800
September 17, 2012: 4,100
January 15, 2013: 1,600
Total: $13,000
