Income received by an ineligible spouse or parent, which is infrequent or irregular, is excluded from deeming if it is within specified limits. In addition, such income is not used in determining the amount of the allocation for an ineligible child or an eligible alien (sponsored by an ineligible spouse or parent). See SI 00810.410 for instructions on applying the infrequent or irregular income exclusion. This exclusion does not apply to income received infrequently or irregularly by an essential person or a sponsor of an alien.
