See your own Social Security tax torpedo

For forty years the promise was simple: defer your taxes now, and you will be in a lower bracket when you retire. Almost no one is shown the stealth tax that can take that lower bracket away, a tax on your own Social Security check. The planners call it the tax torpedo. Put in a few rough numbers and see whether it is aimed at you, and what your real tax rate would be.

Are you married or single?The frozen lines are lower for a single filer, which is part of why this hits widows and widowers hardest.¹

Your annual Social Security benefitFor the household, in today’s dollars. This is the check the tax falls on.

Your other taxable incomeIRA and 401(k) withdrawals, pensions, part-time work, taxable interest. Everything except your Social Security.

Tax-exempt interest (optional)Municipal bond interest, if you have any. Leave blank if none. It still counts toward the line.
