Social Security Tax Calculator
Free
One question many have: How much of my Social Security will be taxed? The answer is found using this free, simple spreadsheet. Enter a few parameters, and the calculator, which replicates the IRS Form 1040 worksheet, will show how much of your Social Security income will be taxed. If you know how much Social Security will be taxed, you can keep taxable income below your Standard Deduction or in a lower tax bracket by strategizing ways to reduce it (Hint: Roth conversions before claiming Social Security). Social Security and taxes are covered in “What Would Dad Do? Volume 2 - The Middle Years and Volume 3 - The Later Years”.
Requires the Excel, LibreOffice, or OpenOffice application. The spreadsheet-formatted files are provided at the download link emailed after checkout.
