This tool calculates the amount of Social Security that is taxable when the taxpayer receives a lump sum (retroactive) payment. There are two methods for calculating the taxable amount of a lump sum payment. The payment can either be left as part of the Social Security payments for the current year, or if the payment is for benefits in a previous year, you may be able to reduce the taxable amount by determining how much of the payment would have been taxable if you had received it in the year it was intended.
