Moving to new state during tax year
My retired parents moved from CA to AZ during 2023. My dad's 1099-R for his retirement from a private company lists the state distribution amounts for each state along with the payer's state no. in boxes 15 & 16 (no state or federal taxes are withheld).
My mom gets a pension from the State of CA and has federal and CA state taxes deducted (no state taxes will be withheld in 2024). Her 1099-R has the information for CA only listed in boxes 14 & 15, with nothing in box 16.
Should I split the amount of the gross distribution in box 1 between both states using their move date to determine the appropriate figure and enter this is box 16? If so, would I use the payer's state no. listed for AZ from my dad's 1099-R and enter that same number on my mom’s 1099-R or leave box 15 payer's state no. blank for AZ?
