So I did some reading and i realized that on some of the very few MFS returns i did i never realized or understood "Community Property Income" so basically when i seen form 8958 i always check "no community property income" and bypassed the form.. as of today neither i or my client has had any issues but as of this year i will no longer ignoring 8958 and will be advising clients that they now have to report comm prop income.. they will prob go somewhere else.. or they might end up filing as mfj.. but if they still want to do MFS I feel like referring them to someone more knowledgeable regarding comm prop income. i did read on pub 555 that if the taxpayer tried obtaining the spouses income and wasnt able to get it then we can put "no" on form 8958 and we must document our files. i have 2 clients who are married to each other but going thru divorce and i mistakenly kept both of them as clients but now i realize i need to either fire both of them and refer them elsewhere due to conflict of interest etc. if any of what i said is wrong please correct me as i am still learning.
