I had a family HDHP covering myself and my wife for Jan - Nov 2019. My wife started her own single HDHP on 01Dec2019 when I started my Medicare coverage. So, we have a family HSA from Jan to Nov and then she has a single HSA from Dec onwards.
TurboTax calculated the contribution limit as $7,334 ( = $8,000/12*11) for the family HSA. TurboTax then calculated max limit for my wife's single HSA contribution as $7,708. We checked "none" for Jan-Nov and "single only" for Dec when answering the question about Type of HDHP Coverage for her.
Questions:
- Shouldn't the max limit for the joint HSA be $7,417 (= $7,000/12*11 + $1,000)?
- How was my wife's single HSA's limit of $7,708 calculated?
- Under the "full-contribution rule", my wife could contribute to her single HSA in 2019 for entire year, assuming that she remains eligible for the whole year in 2020. However, she will start her Medicare coverage in March 2020. How much is the max contribution for her single HSA in 2019 and 2020, respectively?
