Ways to Increase Your Take-Home

📈

A $5,000 401(k) contribution saves $1,100/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 $6,467/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 $539/month to your take-home.

🏥

An HSA could save $1,366/yr in taxes

If you have a High-Deductible Health Plan (HDHP), you can contribute up to $4,400 to an HSA pre-tax. This reduces your taxable income and saves $1,366 in federal and state taxes — a triple tax advantage.
