Taxation of Social Security Benefits


How are Social Security benefits taxed?

Under current law, up to 85 percent of Social Security benefits are subject to federal and state income tax, depending on the taxpayer's income. For taxpayers with provisional incomes less than $25,000 ($32,000 for married joint taxpayers), all Social Security benefits are excluded from taxable income. For provisional incomes between $25,000 and $34,000 ($32,000 and $44,000 for married joint taxpayers), up to 50 percent of Social Security benefits may be subject to tax. For those with provisional incomes over $34,000 ($44,000 for married joint taxpayers), up to 85 percent of Social Security benefits maybe included in taxable income.

What is provisional income?

In determining the amount of Social Security benefits included in taxable income, the provisional income measure used is adjusted gross income excluding Social Security benefits, plus one-half of Social Security benefits. Tax-exempt interest (e.g., from municipal bonds) is also included in provisional income.

What is the average monthly benefit for retired workers?

The average monthly benefit as of November 30, 2009, for couples both receiving benefits is $1,876. This works out to $22,512 per year for a retired couple at the average benefit level. For single recipients the average monthly benefit is $1,112 or $13,344 annually.

The following table shows income levels at which Social Security would be fully exempt, subject to inclusion in taxable income at the 50 percent rate, and subject to inclusion in taxable income at the 85 percent rate for an example couple and single retiree with the average level of benefits. Total income refers to the combination of taxable source income and Social Security.

The table shows that a married couple that receives the average Social Security benefit of $22,152 and has total income from all sources of less than $43,256 is not subject to tax on any Social Security benefits, while a couple with average benefits and total income over $70,709 must include 85 percent of the Social Security, or $19,135, in taxable income. Social Security income included in taxable income is taxed at the same rate as other kinds of income---5.35 percent, 7.05 percent, or 7.85 percent, depending on the total amount of taxable income.
