Ways to Increase Your Take-Home

📈

A $5,000 401(k) contribution saves $1,665/yr in taxes

Married filing jointly saves $13,252/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 $1,104/month to your take-home.

🗺️

Moving to a no-tax state could net $11,347 more per year

States like Texas and Florida have no state income tax. At your salary, moving to Texas would mean $11,347/year more take-home — $946/month — with no change to your gross salary.
