The IRS has announced it is modifying the annual limitation on deductions for contributions to a health savings account (“HSA”) allowed for taxpayers with family coverage under a high deductible health plan (“HDHP”) for the 2018 calendar year. Under Rev. Proc. 2018-27, taxpayers will be allowed to treat $6,900 as the annual limitation, rather than the $6,850 limitation announced in Rev. Proc. 2018-18 earlier this year.
