We reduce Supplemental Security Income (SSI) payments by countable income. For definition
of countable income (CI) refer to SI 00810.300B. When determining CI, consider any income exclusions.
Some exclusions totally negate the amount of income received. Other exclusions reduce
the amount we charge. For example, any income may be wholly excluded (not counted)
if it meets the criteria for exclusion of income received infrequently or irregularly.
