HI, I recently switched jobs. In my old job, there was HSA option that I enrolled and contributed until I left. In the new company, there's again an option to enroll for HSA plan. Can I contribute again to the max allowed? Per IRS, I can contribute as an employee for up to $3400 for single or $6750 as family. I enrolled as latter and contributed to max during enrollment time last year. Can I do the same ($6750) at new place? I see the surcharge with family option is high, need to eat up $600. Thanks!
