I went on Medicare in June 2017. I have an HSA and prior to this time I had a high-deductible health plan. How much can I deposit to my HSA in 2017?
5/12th of your normal limit ($3400 plus $1000 catch up if you had single insurance or $6750 + $1000 catch up if you were covered by a family HDHP plan.) So, $1833 or $3229.
