Social Security and Taxes: The Truth About the 85% Myth (And How to Avoid the Tax Torpedo)

Confused by Social Security?
If there’s one topic that causes more confusion than anything else, it’s how Social Security is taxed. You’ve probably heard: “They tax 85% of your Social Security benefits.”
That sounds scary, like you only keep 15%. But that’s NOT what it means. However, misunderstanding this rule leads retirees straight into the Tax Torpedo.
What the 85% Rule Actually Means
When the IRS says “up to 85% of your Social Security benefits may be taxable,” they mean that up to 85% of your benefit amount is added to your taxable income. It is then taxed at your marginal rate (likely 12% or 22%). You are NOT paying 85% tax.
When Does Social Security Become Taxable?
It depends on your Provisional Income (AGI + Non-taxable interest + 50% of Social Security). If you are married and your provisional income exceeds $44,000, up to 85% of your benefit becomes taxable.
Taxes can quietly erode your benefits.

What Is the “Tax Torpedo”?
The Tax Torpedo is a sudden spike in your marginal tax rate caused by IRA withdrawals. When you take $1 from your IRA, it increases your income, which makes more of your Social Security taxable. This can create an effective tax rate of 40% or more on that withdrawal.
Three Ways to Avoid the Tax Torpedo
- 1. Delay Social Security, Withdraw IRA Funds First: This reduces your RMDs later in life.
- 2. Use Strategic Roth Conversions: Roth withdrawals do not count toward provisional income.
- 3. Coordinate Filing Dates: One spouse’s filing timing affects the household tax bracket.
