Frequently asked questions
Specific to this visa, state, and salary. Sourced to IRS, SSA, and state DOR.
How much does a TN earn after tax on $100,000 in Iowa?
A TN holder grossing $100,000 in Iowa takes home approximately $75,380 per year, or about $6,282/month. Total federal + state + payroll tax burden: $24,620 (24.62% effective rate).
Are TN 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 — $16,100 federal standard deduction is applied (resident alien for tax purposes).
What state taxes apply in Iowa?
Iowa levies a flat 3.80% state income tax. On $100,000 that comes to $3,800.
How much would I save by moving to a no-state-tax state at this salary?
On $100,000, the same scenario in Texas (no state income tax) would net approximately $79,180 — about $3,800/year more than Iowa. Florida, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, and New Hampshire give the same result. Cost-of-living adjustments not included.
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 $5,170 at your 22.00% marginal federal bracket, plus $893 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 TN holders?
Bonuses and RSUs are supplemental wages. Federal supplemental withholding is a flat 22% on amounts up to $1M, then 37% above. Iowa 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.
Does this calculation apply during my first year on TN?
Not necessarily. If you arrive partway through the calendar year, you may not pass the IRS substantial presence test that year and would be classified as a nonresident alien (NRA). NRAs cannot claim the federal standard deduction (~$16,100 loss) and cannot file MFJ. Use the "First-year (NRA)" scenario toggle above, or switch the calculator's Tax residency status to NRA. IRS substantial presence test.
Where do these numbers come from?
