the tax payer received between Jan 1, 2023 and June 1, 2023?
yes
For income received after June 1, 2023 am I correct that will be reported on estate tax return?
it depends. if there was a joint owner (like a spouse) with right of survivorship, it would be that person that would report the post death income. it is necessary to look to who or what becomes the owner/beneficiary of the property producing the income immediately after the death. for an item like wages earned before death but paid after, that would be the estate. for retirement plans and annuities, any named beneficiary(ies) if there are any and they are living (had one case where the spouse was named but she had died years before and her husband never updated the beneficiary form).
