How to Compare Two Job Offers After Tax

A $120,000 offer in California and a $115,000 offer in Texas do not produce the same take-home pay. California taxes wage income at the state level, while Texas does not. After federal tax, FICA, and state withholding, the Texas offer can produce a higher monthly paycheck even with a lower headline number.

This is why comparing gross salary numbers directly is a poor starting point for offer evaluation. The number that actually matters for budgeting is monthly net pay — what lands in your account every month after all withholding.

Start by converting both offers to the same annual salary. If one offer is hourly, multiply by 40 hours per week and 52 weeks. If monthly, multiply by 12. This creates a clean comparison baseline before taxes are applied.

Your filing status — single, married filing jointly, married filing separately, or head of household — changes your federal tax brackets and standard deduction. To compare two offers fairly, apply the same filing status to both. Married filing jointly typically produces a lower effective federal rate than single at the same gross income.

Annual net pay can look like a large number that obscures the day-to-day difference. Monthly net pay connects more directly to rent, bills, savings, and spending. A $400/month take-home difference is more immediately understandable than a $4,800 annual difference that might feel abstract.

For a $120k California offer versus a $115k Texas offer (single filer, biweekly), the monthly net pay difference often favors Texas despite the lower gross salary. Run both through the UsefulTax calculator to see the specific numbers for your scenario.

Once you have a baseline comparison, test one variable at a time. What happens if you negotiate the California offer up to $125k? Does it flip the result? What if you change filing status to married? This step-by-step sensitivity check helps you understand how much salary difference it takes to close the tax gap between two states.

The UsefulTax calculator uses simplified state tax assumptions and does not model every local tax, pre-tax benefit deduction (like 401k contributions), or personal tax credit. Real paychecks can differ from estimates. Use these numbers for directional planning, not for filing decisions or precise budgeting.

1. Convert both offers to annual salary. 2. Select the same state and filing status for each estimate. 3. Compare monthly net pay first. 4. Check the per-paycheck view if frequency matters (biweekly vs. semimonthly). 5. Run a sensitivity check: how much does the lower offer need to increase to match after-tax results?
