Ways to Increase Your Take-Home

📈

A $5,000 401(k) contribution saves $1,908/yr in taxes

💍

Married filing jointly saves $8,679/yr

If you're married, filing jointly gives you a $32,200 standard deduction (vs $16,100 single) and wider tax brackets. This would add $723/month to your take-home.

🗺️

Moving to a no-tax state could net $7,540 more per year

States like Texas and Florida have no state income tax. At your salary, moving to Texas would mean $7,540/year more take-home — $628/month — with no change to your gross salary.
