Other taxable income	$35,000

What if I take more income?

Holding your Social Security and tax-exempt interest fixed, here’s how taxable benefits change as other income rises (IRA, pension, wages, etc.).

Other income	Provisional income	Taxable Social Security	% of SS
$10,000	$27,000	$1,000	3.3%
$20,000	$37,000	$7,050	23.5%
$30,000	$47,000	$15,550	51.8%
$40,000	$57,000	$24,050	80.2%
$50,000	$67,000	$25,500	85%
$60,000	$77,000	$25,500	85%
$80,000	$97,000	$25,500	85%

Estimated federal tax impact

Using a simplified 12% bracket model with a standard deduction estimate: federal tax attributable to including Social Security in income is about $2,376. Rough tax on taxable SS at your selected 12% rate: $2,376. Actual tax depends on your full return.

Why did my taxable Social Security increase?

Extra IRA or pension income can push provisional income into the 50% or 85% zone — the Social Security tax torpedo — where each dollar of withdrawals can make more of your benefits taxable.
