Deductions & credits

It depends on the total amount of income she recieved in 2023. 

Just like anyone else, a deceased taxpayer's return must be filed if the total income exceeds the filing threshold for her filing status. See the chart below to find the amount of income that requires a return be filed. 

If a final 1040 is required, you would include all income received before the date of death. 

I am sorry for your loss. If you need additional help, or have more questions, please feel free to reach out again.
