Deceased person's tax return when to file
My mother passed away in February, 2021. She is due a refund on her 2020 tax return. So, I have to mail in her return. Cannot file it electronically.
My question is, is there any reason that I should NOT go ahead and submit her return for 2020 now so the IRS can start processing her refund?? Her refund that is due is a pretty substantial amount and I don't want the IRS to keep the money any longer than necessary.
Thank you.
