A modified benefit formula is used to compute Social Security benefits for persons entitled to both a pension or annuity based on employment after 1956 not covered by Social Security and a Social Security retirement or disability insurance benefit. The difference in your Social Security benefit computed under the modified formula, rather than the regular benefit formula, cannot be greater than one-half the amount of the pension or annuity you received in the first month you are entitled to both the pension or annuity and the Social Security benefit. |
