📈

A $5,000 401(k) contribution saves $2,048/yr in taxes

If you're married, filing jointly gives you a $32,200 standard deduction (vs $16,100 single) and wider tax brackets. This would add $1,080/month to your take-home.

🗺️

Moving to a no-tax state could net $9,234 more per year

States like Texas and Florida have no state income tax. At your salary, moving to Texas would mean $9,234/year more take-home — $769/month — with no change to your gross salary.
