Taxation of Social Security Benefits

Most retirees are aware that the government taxes retirement income from tax-deferred retirement savings and pensions. But the federal income tax on Social Security often catches retirees by surprise, driven partly by the fact that it’s not always clear who owes it and how much they owe.

The Social Security reforms that instituted the federal income tax legislated that the income thresholds for taxation would not be indexed for inflation. The goal was that the tax would start out affecting a relatively small part of the enrolled population but grow over time. The has held true: as recently as 1999, only 7.4% of beneficiaries paid taxes on benefits. But today, about half of Social Security beneficiaries do, and that figure is continuing to rise.

The formula used to determine whether some portion of your benefit will be taxed is unique to Social Security and starts with calculating your “provisional income”:

Provisional Income = Adjusted Gross Income + Nontaxable interest + 50% of your Social Security benefit

From there, you can determine how much of your Social Security benefits are subject to taxes:

Filing Status Provisional Income – Amount of benefit subject to tax
Married filing jointly Under $32,000 – 0%
$32,000 to $44,000 – up to 50%
Over $44,000 – up to 85%
Single, Head of Household, Qualifying Widow(er)
Married filing separately and not living with spouse
Under $25,000 – 0%
$25,000 to $34,000 – up to 50%
Over $34,000 – up to 85%
Married filing separately and living with spouse Over $0 – up to 85%

The IRS has a helpful calculator to determine if any part of your benefits is taxable.
