A lump-sum of social security benefits is usually included in gross income for the year in which it is received. However, a recipient may choose to include in gross income the total amount of benefits that would have been included in gross income in the appropriate year if the payments had been received when due.

Lump-sum payments

If a recipient attributes benefits to a prior tax year, a smaller portion of the benefits may be subject to tax. This can occur when (1) a recipient's modified adjusted gross income (AGI) in the current year is more than the prior tax year's AGI or (2) a recipient used a higher base amount due to filing status in the prior year.

The IRS provides worksheets to assist recipients in determining whether they should attribute retroactive benefits to a prior tax year. Once the decision is made, IRS consent is needed to revoke it. A taxpayer who fails to attribute benefits to a prior year must include the lump-sum payment with income for the year in which the payment is received.

Repayment of benefits

When a recipient has to repay excessive benefits that were paid in error, the repayments reduce the amount of benefits taken into account for tax purposes in the year the repayment is made. Repayments are shown separately on the individual's Form SSA-1099, Social Security Benefit Statement.

If the repayment occurs during the same year the benefits are received, an adjustment is made for that year. If the repayment is made in a subsequent year, the recipient subtracts the repayment from the benefits received in the repayment year.

Example.  Shane received $7,500 in social security benefits in year 1 and $7,500 in year 2. In year 2, the Social Security Administration informed him that he should have only received $7,000 in benefits for each year. Shane immediately repaid $1000 in year 2. His taxable benefits for year 2 are as follows:

• Benefits received in year 2 = $7500,
• Repayments made in year 2 = $1000,
• Taxable benefits for year 2 = $6500 ($7500-$1000).
