Contributions to a Roth IRA are made with after-tax dollars — you don't receive a tax deduction for money you put into a Roth IRA. Not only does the Roth IRA offer tax-deferred growth, but qualified Roth distributions including earnings are not subject to income taxation. And the tax-free treatment of distributions applies to beneficiaries who may inherit your Roth IRA.
Municipal, or tax-exempt, bonds are issued by state and local governments to supplement tax revenues and to finance projects. Interest from municipal bonds is usually exempt from federal income tax. Also, municipal bond interest from a given state generally isn't taxed by governmental bodies within that state, though state and local governments typically do tax interest on bonds issued by other states.
Health Savings Accounts
A health savings account (HSA) lets you set aside tax-deductible or pre-tax dollars to cover health-care and medical costs that your insurance doesn't pay. HSA funds accumulate tax-deferred, and qualified withdrawals are tax-free. While an HSA is intended to pay for current medical and related expenses, you don't necessarily have to seek reimbursement now. You can hold your HSA until retirement then reimburse yourself for all the medical expenses you paid over the years with tax-free HSA distributions — money you can use any way you'd like. Be sure to keep receipts for medical expenses you incurred.
