(a) We receive your modified adjusted gross income from IRS for the more recent tax year we used or a later tax year;
(b) Your more recent tax year modified adjusted gross income that we used is for a tax year more than 3 years prior to the income-related monthly adjustment amount effective year;
(c) You request we use a more recent tax year based on another major life-changing event as described in § 418.1201; or
(d) You notify us of a change in your modified adjusted gross income for the more recent tax year we used as described in § 418.1240.
