Employee received a W-2 showing box 12 Code W of $7900. Taxpayer is 50 years old, with a family HSA. It appears to me the limit is $6900 for 2018. This is a very large employer, with tons of employees, so I feel like I must be missing something.
However, if employer put in $1,000 too much, I know there is a 6% tax to be paid. Would client also have to withdraw the $1,000?
