Ways to Increase Your Take-Home

📈

A $5,000 401(k) contribution saves $1,730/yr in taxes

Pre-tax 401(k) contributions reduce your federal and state taxable income. Contributing an additional $5,000 would increase your monthly take-home by $417 while building retirement savings.

💍

Married filing jointly saves $5,439/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 $453/month to your take-home.

🗺️

Moving to a no-tax state could net $4,688 more per year

States like Texas and Florida have no state income tax. At your salary, moving to Texas would mean $4,688/year more take-home — $391/month — with no change to your gross salary.
