Ans: If your income after retirement is lower than $25000, you will get a total tax rebate. Other parameters are used to calculate the value as well. For that, you can use the tax-efficient retirement withdrawal planning calculator. After retirement, you can start a small business, too. Hence, you won’t have to keep on relying on CDs or bonds as alternative earning sources. And there is tax credits for small business retirement plans too. When you retire from your business, you can get other tax benefits.
