1. What is Social Security Taxable Income?

Social Security benefits may be taxable depending on your combined income (adjusted gross income + nontaxable interest + half of your Social Security benefits). The percentage of benefits subject to tax ranges from 0% to 85% based on income thresholds and filing status.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Taxable SS} = \text{SS benefits} \times \text{percentage (based on income thresholds)} \]

Where:

$ \text{SS benefits} $ — Your total Social Security benefits received
$ \text{percentage} $ — 0%, 50%, or 85% based on combined income and filing status
$ \text{combined income} $ — Other income + 50% of SS benefits

Thresholds for 2023:

Single/Head of Household: 0% below $25,000, 50% between $25,000-$34,000, 85% above $34,000
