Determining Taxability with Provisional Income
To determine if your Social Security benefits are taxable, the Internal Revenue Service (IRS) uses a calculation based on your “provisional income” or “combined income”. This calculation considers your income from other sources along with a portion of your Social Security benefits.
Calculating Your Combined Income
Your combined income is calculated by adding your Adjusted Gross Income (AGI), any tax-exempt interest (such as from municipal bonds), and one-half of the Social Security benefits you received during the year. This figure is then used to determine if your benefits are taxable and at what level.
Federal Income Tax Thresholds
The amount of your Social Security benefits subject to federal income tax depends on your combined income and filing status. For single, head of household, or qualifying widow(er) taxpayers, if combined income is $25,000 or less, none of the benefits are taxable. Between $25,001 and $34,000, up to 50% may be taxable, and above $34,000, up to 85% may be taxable.
For married taxpayers filing jointly, if combined income is $32,000 or less, none of the benefits are taxable. Between $32,001 and $44,000, up to 50% may be taxable, and above $44,000, up to 85% may be taxable.
For married individuals filing separately who lived with their spouse at any time during the year, the threshold is $0, and up to 85% of benefits could be taxable. If they lived apart for the entire year, the single filing status thresholds apply.
Example Calculation
Consider a single retiree with $15,000 AGI, $2,000 tax-exempt interest, and $18,000 in annual Social Security benefits. Their combined income is $15,000 (AGI) + $2,000 (tax-exempt interest) + $9,000 (half of benefits) = $26,000. Since $26,000 falls within the $25,001 to $34,000 range for a single filer, up to 50% of their Social Security benefits may be taxable, with the exact amount determined by specific calculations based on the bracket.
Understanding Taxable Percentages
The 50% and 85% figures refer to the maximum percentage of your benefits that can be included in your taxable income, not the tax rate itself. The taxable portion is added to your other income and taxed at your regular federal income tax bracket.
Additional Factors Affecting Taxability
In addition to federal rules, state taxes can also apply to Social Security benefits in some states. You can also choose to have federal taxes withheld from your benefits by submitting Form W-4V to the SSA to help manage your tax bill. Tax-advantaged retirement accounts like Roth IRAs can offer tax-free withdrawals which don't count towards combined income.
