Make sure that the amount of your combined contribution does not exceed the annual limit when you Convert 401k to Gold IRA. While the traditional IRA shares many features with its newer sister, the Roth IRA offers tax incentives to save for retirement and, under certain circumstances, each of them is governed by a different set of rules. Initial tax relief is one of the main things that differentiate the rules of traditional IRAs from Roth IRAs, in which taxes are not allowed to be deducted for contributions.
