Unretirement calculator showing Social Security earnings test and tax impact for 2026

What this calculator helps you decide

“Unretirement” (going back to work after you’ve started retirement) can be a smart move — but the financial tradeoffs aren’t always obvious. This calculator estimates how much income you can earn before certain benefits are reduced, and it shows how earnings can affect your Social Security check and your federal tax picture.

Key point: If you take Social Security before Full Retirement Age (commonly age 67), wages and self-employment income may trigger the Social Security earnings test, which can temporarily withhold part of your benefit. This tool estimates that withholding for you based on your age and “unretirement” income.

Why this matters

  • Work full time: you may earn more, but you could lose (or temporarily forfeit) important benefits and/or trigger higher taxes.
  • Work part time: you may protect benefits, but you may not earn enough for it to be worthwhile.
  • Finding the “sweet spot”: this calculator helps you see when additional earnings improve your net spendable income — and when they don’t.

The results include an estimate of (1) Social Security benefits withheld under the earnings test (if applicable), (2) how much of your Social Security may become taxable based on provisional income rules, (3) an estimated deduction “shield,” and (4) a simplified estimate of federal income tax — to show a practical net spendable income estimate.

Important note about withheld benefits: If benefits are withheld due to the earnings test, Social Security may later adjust your benefit upward after you reach Full Retirement Age to account for months withheld. This calculator treats withholding as a near-term cash-flow impact (what you can spend now).
Disclaimer: This calculator provides educational estimates only and is not tax, legal, or financial advice. Tax rules change, individual situations vary, and this tool uses simplified assumptions. You must verify results using official IRS and Social Security guidance and/or a qualified professional before making decisions. By using this tool, you agree you are responsible for confirming accuracy and suitability for your situation.
