A health savings account (HSA) is a way to save for medical expenses and lower insurance premiums. With an HSA, you can contribute pre-tax money to use for eligible healthcare expenses. These expenses can include medical, dental, and vision costs. By setting aside money in an HSA, you can reduce your taxable income and save on taxes. Additionally, having an HSA may allow you to choose a high-deductible health insurance plan with lower premiums. This can be beneficial if you're generally healthy and don't require frequent medical care. It's important to compare different insurance options and consider your healthcare needs before making a decision.
