First, you must be a citizen or resident alien. Second, you may not average if you or your spouse provided less than 50% of your support during 1981, 1982, and 1983, unless (a) you were 25 or older at the close of 1984 and weren't a full-time student during four of the taxable years after you reached 21; (b) more than 50% of your 1984 income came from work performed in 1981, 1982, and/or 1983; (c) your spouse's earnings were less than 25% of your joint 1984 income and you were self-supporting in 1981, 1982, and 1983. Owner-employees and key employees may not average premature distributions from retirement plans.
