Starting January 2026: if one spouse monthly Soc Sec (age 65) will be $900 and the other spouse monthly Soc Sec (age 66/10 months) will be $3900 plus this spouse will work part-time and earn $5900/month. Assume couple lives in Michigan and is filing married/jointly. How should they set tax withholding to break-even/owe very little in income taxes at year end assuming this level of social security income (85% taxed right?)
