Comprehensive Example
Determining Your Traditional IRA Deduction and
the Taxable Portion of Your Social Security Benefits
  John Black is married and files a joint return. He is 65 years old and had 2017 wages of $90,500. His wife didn’t work in 2017. He also received social security benefits of $12,000 and made a $6,000 contribution to his traditional IRA for the year. He had no foreign income, no tax-exempt interest, and no adjustments to income on lines 23 through 36 on his Form 1040. He participated in a section 401(k) retirement plan at work.
  John completes worksheets 1 and 2. Worksheet 2 shows that his 2017 IRA deduction is $5,950. He must either withdraw the contributions that are more than the deduction (the $50 shown on line 8 of Worksheet 2), or treat the excess amounts as nondeductible contributions (in which case he must complete Form 8606 and attach it to his Form 1040).
  The completed worksheets that follow show how John figured his modified AGI to determine the IRA deduction and the taxable social security benefits to report on his Form 1040.
