Social Security benefits may be tax free or includible in gross income at 50% or 85%. This depends on a couple’s income, Social Security benefits, and tax-exempt interest. The fact that the benefits are payable to a third party does not change the tax result; the Social Security checks are being used for the taxpayer’s benefit.
Eligible taxpayers may claim a tax credit for 10%, 20%, or 50% of up to $2,000 of retirement plan contributions.
