We will now have an opportunity to save for medical expenses in a completely tax-free manner. Contributions to the Health Savings Account will be tax-deductable up to $2,250 per individuals or $4,500 per family. [Unfortunately, the HSA is the only good part of the new Medicare bill, which (big surprise) greatly increases government-spending.]
If you want more information on HSA's, MSA Bank's website provides an excellent resource center on HSA's -- with the latest news, and a summary of HSA's.
If you just want the low-down on HSA's, this summary provides a quick chart comparing them to MSA's and enumerating their features.
HSA's should provide an excellent way to save for possible medical expenses, and should provide a contingency plan -- if not another plan entirely -- to save for retirement.
