TT answer was wrong since it's saying that between the two of you, the total contributions to both HSA's can exceed $9,000 - yours $8000 hers $1334. I agree with Dmertz. the maximum family contribution if both are over 55 but neither is covered by Medicare is $9000. $7000 family and $1,000 catch up contribution made to each to taxpayer's HSA a/c. If only one spouse had an HSA the Max would be $8,000 since the catch up must go into each spouses HSA. Since you contributed $8,000 to your HSA that leaves only the catch up for your spouse since she went on Medicare in March her catchup must be prorated for the months she was not so covered so your computation of 2 * 1000 /12 = 167 is correct.
