Simplified Method
You must use the Simplified Method if either of the following applies.
Your annuity starting date was after July 1, 1986, and you used this method last year to figure the taxable part.
Your annuity starting date was after November 18, 1996, and both of the following apply. The payments are from a qualified employee plan, a qualified employee annuity, or a tax-sheltered annuity. On your annuity starting date, either you were under age 75 or the number of years of guaranteed payments was fewer than 5. See Pub. 575 for the definition of guaranteed payments.
If you must use the Simplified Method, complete the Simplified Method Worksheet in these instructions to figure the taxable part of your pension or annuity. For more details on the Simplified Method, see Pub. 575 (or Pub. 721 for U.S. Civil Service retirement benefits).
If you received U.S. Civil Service retirement benefits and you chose the alternative annuity option, see Pub. 721 to figure the taxable part of your annuity. Do not use the Simplified Method Worksheet in these instructions.
