Frequently asked questions
Specific to this visa, state, and salary. Sourced to IRS, SSA, and state DOR.
How much does a L-1 (married filing jointly) earn after tax on $100,000 in Illinois?
A L-1 holder (married filing jointly) grossing $100,000 in Illinois takes home approximately $79,760 per year, or about $6,647/month. Total federal + state + payroll tax burden: $20,240 (20.24% effective rate).
Are L-1 holders subject to FICA in this scenario?
Yes. Social Security 6.2% up to $184,500 (2026 wage base), Medicare 1.45% on all wages, plus 0.9% additional Medicare above the filing-status threshold.
Can the standard deduction be claimed in this scenario?
Yes — $32,200 federal standard deduction is applied (resident alien for tax purposes).
What state taxes apply in Illinois?
Illinois levies a flat 4.95% state income tax. On $100,000 that comes to $4,950.
How much would maxing out a 401(k) save me at this income?
Contributing the 2026 IRS limit of $23,500 pre-tax to a 401(k) would reduce federal income tax by roughly $2,820 at your 12.00% marginal federal bracket, plus $1,163 in state tax. (Note: 401(k) contributions still count as FICA wages, so Social Security and Medicare are unchanged.)
How are bonuses and RSU vesting taxed for L-1 holders?
Bonuses and RSUs are supplemental wages. Federal supplemental withholding is a flat 22% on amounts up to $1M, then 37% above. Illinois applies its standard income-tax rules. FICA still applies if the visa is not FICA-exempt. This is withholding, not the final tax — high earners often underwithhold and owe at filing time.
When is filing jointly better than filing separately for an H-1B holder?
MFJ is almost always better than MFS for couples where one spouse earns significantly less than the other. The MFJ standard deduction is exactly 2× single ($32,200 vs $16,100 for 2026), and the brackets are wider in the lower bands. The exception is when both spouses earn roughly the same and one has very high deductions or income-driven student-loan payments tied to taxable income.
