We have a client who has a joint brokerage account with her deceased husband, reporting under his SSN. He passed in 2022 and the account was never changed into an individual under her name/ssn. We are changing that now, May 2024. She had a consolidated 1099 for 2023 and will have one for beginning months of 2024 reporting under his SSN. How does she file taxes? She lives in Nevada.
