I was self-employed most of my career and, after years of increasing, staggering, barely affordable health insurance premiums as a single person, I was introduced to HSAs (Health Savings Account). They are not a solve-all for the high cost of health insurance premiums but they offer tax savings when the money you invest in an HSA is used to off-set medical expenses with a high deductible insurance plan. Any funds you invest are pre-tax dollars when you invest and also when you withdraw the funds for approved medical expenses and some OTC medical expenses.
Since I've been relatively healthy, and always carried a high deductible plan to keep my premiums low, an HSA was a good fit for me. They are different from FSAs (flex plans) in that your contribution rolls over every year, you never lose it. When I was finally eligible for Medicare, the funds left in my HSA account could be rolled over for my first few Medicare premiums. tax free. HSAs are similar to an IRA retirement plan with different restrictions and rules.
If you are on an HSA and had positive or negative experiences, I'd be interested in your comments.
