Hi, I’m helping my parents with their taxes and just want to confirm I’m understanding this correctly. They both receive OAS and GIS, along with very small income from CPP and a bit of interest. In 2025, their total income shows around $28k-$29k, but this is mainly due to a GIS lump sum (retroactive payment from 2024). From what I understand, GIS is non-taxable, and their actual taxable income is still very low (around $2k-$4k). I just want to ask if this lump sum will affect their future GIS payments, and when claiming a parent as an eligible dependant (line 30400), should I ignore GIS and only consider taxable income? Also, is this something CRA might question or reassess? Thanks!
