A mid-level software engineer in Austin, TX is comparing a $130,000 W-2 offer against their current $115,000 role. The new offer includes a $10,000 signing bonus and 0.1% equity in a Series B company.
Takeaway: Texas has no state income tax, which inflates take-home vs. the same offer in California (~9.3% marginal) or New York (~6.85%). Run the comparison with your state's rate above.
Take-home calculators estimate withholding based on single/married status and claimed allowances. If you have side income, multiple jobs, or itemized deductions, your actual withholding will differ. The IRS Tax Withholding Estimator is the most accurate tool for W-4 calibration.
Nine states have no income tax (TX, FL, WA, NV, AK, SD, WY, TN, NH). California tops out at 13.3% marginal. State tax can shift your net paycheck by $200-$1,000/month on a $100K salary. Always select your state before reading take-home results.
Cost of Living Salary AdjustmentEmployer-paid health insurance, 401(k) match, HSA contributions, and paid leave have real dollar value — typically $8,000-$25,000/year for a mid-career employee. Comparing two offers on base salary alone ignores a major component of total compensation.
Benefits Value CalculatorW-2 employees pay 7.65% FICA (SS + Medicare); employers match it invisibly. 1099 contractors pay the full 15.3% self-employment tax. A $100K 1099 contract has roughly $7,650 more tax friction than a $100K W-2 salary before any other adjustments.
1099 vs W-2 Tax ComparisonBonuses are withheld at a flat 22% federal supplemental rate (or 37% over $1M) — not your effective rate. Your actual tax on the bonus is determined at year-end filing. If your marginal rate is below 22%, you'll get a refund; above, you may owe.

An employer match is free money your company adds to your 401k when you contribute. A common match is 50% up to 6% of salary.
The most common employer match is 50% of employee contributions up to 6% of salary, effectively giving employees 3% of salary in free money.
Absolutely. The employer match is an immediate 50-100% return on your investment. Always contribute at least enough to get the full match.
Vesting determines when you own the employer match. Immediate vesting means it's yours right away. Graded vesting means you gain ownership over several years.
For 2024, employees can contribute up to $23,000 per year ($30,500 if age 50+). Total contributions including employer match cannot exceed $69,000 ($76,500 for 50+). These limits increase annually with inflation adjustments.
A 3% employer match on a $75,000 salary adds $2,250 per year. Invested over 30 years at 7% average returns, that match alone grows to approximately $215,000. This is why financial advisors call it the best historically reliable return available.
You always keep your own contributions. Employer match vesting schedules vary: cliff vesting gives 100% ownership after 3 years, graded vesting gives 20% per year over 6 years. Unvested employer contributions are forfeited when you leave.
The employer match is always deposited as pre-tax (traditional) money regardless of whether you choose Roth contributions. If you expect higher taxes in retirement, Roth contributions for your portion make sense while the match grows tax-deferred.
Employer 401k match contributions are not included in your current taxable income. They grow tax-deferred until withdrawal in retirement. At withdrawal, both the match and its earnings are taxed as ordinary income, just like traditional 401k contributions.
Total combined employee and employer contributions cannot exceed $69,000 in 2024 ($76,500 with catch-up for age 50+). There is no separate cap on employer match percentage, but employer contributions plus your deferrals must stay within this annual limit set by the IRS.
Employer Match = Salary × min(Your%, Cap%) × Match Rate%
Example: $75k × 6% × 50% = $2,250/year free money
