hsa deduction

[MJGF]

I had a HDHP (family plan) through my employer up until August 2023.  I retired and my spouse and I moved to Medicare Part B on August 1. We are both over 65.  Based on TT calculation we have a HSA limit of $5104.  I assume that is for 2023.  Can I contribute that amount into my HSA now and claim it as a deduction for 2023?  If how do I do that?  Thanks.

for a 2023 deduction, it must be made to your HSA by 4/15/2024. 

family plan full year amount $7750

prorated for 7 months =4521

catch up over 65 full year amount $1000

prorated for 7 months=  583

total $5104 as TurboTax computed

on the Turbotax 8889 check that you had full-year coverage through July and none after that. enter on line 2 your contrbutuion for 2023 even if made after 12/31/2023 but by 4/15/2024

also note that if wanted your spouse could establish her own HSA and being over 65 could contribute $583 for 2023. it has to be to her account not yours.

It seem unlikely that you were HSA-eligible for 7 months.  You didn't say when each of you reached age 65, but if you both were past age 65 when signing up for Medicare Part B and signed up for Medicare Part A as the same time, it seems likely that your coverage for Medicare Part A would have been retroactive to some month before August (6 months before but not before the month you reached age 65), which would make you HSA eligible for less than 7 months of 2023.  If you both reached age 65 before 2023 and signed up for Part A with coverage beginning the first of the month that you reached age 65, you are both ineligible to contribute to an HSA for 2023.
