Will you pay higher taxes in retirement? Do you have a lot of money in a 401(k) or a traditional IRA? If so, you may receive significant retirement income. Those income distributions, however, will be taxed at the usual rate. If you have saved and invested well, you may end up retiring at your current marginal tax rate or even a higher one. The jump in income alone resulting from a Required Minimum Distribution could push you into a higher tax bracket.
