If your family is covered under a High-Deductible Health Plan (HDHP), you have new inflation-adjusted limits on your 2020 deductions for contributions into your HSA.
“High deductible health plan. For calendar year 2020, a “high deductible health plan” is defined under § 223(c)(2)(A) as a health plan with an annual deductible that is not less than $1,400 for self-only coverage or $2,800 for family coverage, and the annual out-of-pocket expenses (deductibles, co-payments, and other amounts, but not premiums) do not exceed $6,900 for self-only coverage or $13,800 for family coverage.”
If you are an individual contributing to an HSA, your annual limit on contributions that are deductible has increased from $3,500 to $3,550 for 2020. The family coverage limit on deductible contributions has increased from $7,000 to $7,100 in 2020.
