Biweekly (every two weeks, 26 pay periods) is not the same as semi-monthly (twice a month, 24 pay periods). Semi-monthly checks are slightly larger because there are two fewer of them per year.

Frequently Asked Questions

What is the take-home pay on $500,000 in Iowa?
For a head of household filer earning $500,000 in Iowa (tax year 2026), the take-home pay is approximately $327,103 per year after $133,506 federal income tax, $21,389 in FICA (Social Security and Medicare), and $18,002 in state and local taxes. This is an effective tax rate of 34.58%.
Does this include pre-tax deductions like 401(k), HSA, or health insurance premiums?
The numbers on this page assume no pre-tax deductions. If you contribute to 401(k), HSA, healthcare FSA, or dependent care FSA, your actual federal tax will be lower. Use the live calculator to model exact pre-tax deductions — it applies them to your federal taxable wages and, for verified states (currently Pennsylvania, Michigan, and California), to your state taxable wages too.
Why does my actual paycheck differ from this estimate?
Common reasons: (1) pre-tax deductions your employer withholds — if you haven't entered them in the live calculator, your paycheck shows lower taxes; (2) W-4 withholding is an IRS safe-harbor estimate, not your true tax owed — you reconcile at filing; (3) state and local tax credits (EITC, property tax relief, child tax credit) that we don't model; (4) post-tax deductions like Roth 401(k) contributions or wage garnishments; (5) multiple jobs or side income changing your effective bracket.
What HSA contribution limit should I use — self-only or family?
The live calculator caps HSA input at the 2026 family limit ($8,750). If you have self-only HDHP coverage, your limit is $4,400 — enter no more than that. The age-55+ HSA catch-up contribution ($1,000) is not yet modeled. HSA contributions are pre-tax for FICA only when made through a §125 cafeteria plan (standard employer payroll deduction); standalone HSA contributions are post-FICA-tax.
Why is the Dependent Care FSA limit $7,500 now?
The One, Big, Beautiful Bill Act (signed July 2025) raised the Dependent Care FSA limit from $5,000 to $7,500 starting tax year 2026. For married filing separately, the limit is $3,750 (raised from $2,500). The live calculator applies the correct limit based on your filing status. This is the first DCFSA limit increase since 1986.
Can I add 401(k) or HSA catch-up contributions for older taxpayers?
Not yet. The live calculator exposes only the regular limits ($24,500 for 401(k), $8,750 for HSA family). Age-50+ adds $8,000 to 401(k) under §414(v); age-60-63 adds $11,250 under SECURE 2.0; age-55+ adds $1,000 to HSA under §223(b)(3). Catch-up support is on the roadmap; for now, treat the calculator's results as an upper bound on tax for older filers using catch-up.
What does 'verified' mean on this site?
A state or city is verified when its tax tables, rates, and brackets have been cross-checked against the official Department of Revenue publications for the given tax year. We list our primary-source citations on every page. Unverified jurisdictions are excluded from search indexing (with a noindex tag) and labeled "coming soon" — we don't show approximate data presented as authoritative. As of tax year 2026, six US jurisdictions are verified.
What is the difference between effective and marginal tax rates?
Your effective tax rate (34.58%) is your total tax divided by your gross income — the average percentage of your income that goes to taxes. Your marginal tax rate (41.15%) is the rate that applies to your next dollar of income. Marginal rates are always equal to or higher than effective rates in a progressive tax system.
How does Iowa income tax work?
Iowa imposes a flat individual income tax of 3.8% on taxable income under Iowa Code §422.5, effective TY2025 forward per SF 2442 (May 2024). Taxable income is federal adjusted gross income minus the standard deduction (federal-conforming under §422.9: $16,100 single / $32,200 MFJ for TY2026). The computed tax is reduced by a per-filer + per-dependent personal credit of $40 per credit (see the next FAQ for the credit mechanism). The 3.8% rate is held for TY2026 per the Iowa Department of Revenue press release of October 21, 2025.
How does Iowa's $40 personal credit work?
Iowa applies a personal credit of $40 per filer ($80 for joint or head-of-household filers per IA-1040 Step 3 line a — "Enter 1 (enter 2 if filing status 2 or 4)" where status 2 = MFJ and status 4 = HoH) plus $40 per dependent. The credit is subtracted from the computed tax (rate × taxable income), floored at $0 — the credit does not produce a refund. For a single filer with 0 dependents, the credit is $40; for a joint filer with 2 dependents, the credit is $160; for a head-of-household filer with 2 dependents, the credit is $160 (2 personal credits × $40 + 2 dependent credits × $40). Iowa's HoH-as-2-credits convention contrasts with California's HoH-as-1-credit convention; this calculator handles both conventions via a per-state schema override.
Does Iowa have local income taxes?
No. Iowa does not impose municipal or county income taxes. The state imposes only the state income tax. This calculator returns Iowa state tax only.
What if I itemize federal deductions instead of taking the standard deduction?
This calculator applies the standard deduction ($24,150 for Head of Household). If you itemize using IRS Schedule A — typically when your mortgage interest, state and local taxes (capped at $10,000), charitable donations, and qualified medical expenses exceed the standard deduction — your federal taxable income will differ. We don't model itemization because it requires line-by-line input and is highly individualized. Use IRS Schedule A worksheets or consult a tax professional for itemized scenarios.
How accurate is this calculator?
Federal income tax, FICA (Social Security + Medicare + Additional Medicare), and state income tax are computed from official 2026 IRS, SSA, and state Department of Revenue tables. This page assumes no pre-tax deductions, no itemized deductions, no tax credits, and W-2 wage income only. The live calculator supports 401(k)/HSA/FSA pre-tax deductions; itemized deductions, credits, self-employment income, and multi-state allocation aren't modeled.
