I'm have to decide which tax rate to have taken out of Social Security. Spouse is employed, making 135k / year. We will file jointly.

Instead of having withholding from your SS payment  your spouse can increase their withholding at work ... on the W-4 form they would add your SS income on line 4a.  They can also choose the SINGLE status instead of Married.
