Head of household was being short-changed a $8,050 deduction in nine states
Nine states adopt the federal standard deduction by reference, and the site recorded that fact in a flag — but the flag was decorative. The engine read a separate table where head of household fell back to the SINGLE amount, $16,100 instead of the federal $24,150. Eight of the nine were therefore overstating tax for head-of-household filers by between $157 and $580 a year at a $75,000 salary: Colorado, DC, Idaho, Iowa, Missouri, Montana, New Mexico and North Dakota. Arizona had the right figure written out by hand and was unaffected. The flag is now load-bearing and a test fails if a state claims to follow the federal deduction without actually doing so.

Vermont was a year behind, and two filing statuses were on the wrong schedule
Vermont’s bands here were its 2025 schedule exactly — not indexed figures that happened to be close, as previously assumed, but last year’s numbers. Married filing separately and head of household were both falling back to the single schedule, which in Vermont is badly wrong: head of household’s first boundary is $15,450 higher, and married filing separately is exactly half the joint schedule. All four statuses corrected. Vermont publishes no 2026 rate schedule at all, so the bands are derived from its 2026 withholding table; the derivation reproduces the published 2025 schedules to the dollar, and Vermont’s own printed base-tax column confirms the 2026 result to the cent.

New Mexico resolved — and it puts head of household on the married schedule
New Mexico had been unverifiable because its withholding tables print single, married and head-of-household side by side and a plain text extraction interleaves the three columns into plausible nonsense. Extracting with the page layout preserved separates them. The bands then confirm ours exactly. It also revealed that New Mexico puts head of household on the MARRIED schedule rather than the single one, which we had been applying — worth about $200 a year to those filers.

Spanish
The calculator, a Spanish home page and all 51 state pages are now available at /es. Not a translation of the English text — the questions people ask in Spanish about a US paycheck are different ones, and the most common of them (whether payroll tax applies when you work on an ITIN — it does, in full) has no English counterpart at all. Every figure comes from the same engine, so the two languages cannot disagree about a number.

The calculator can be embedded on any site, free
One line of HTML at /widget puts the calculator on someone else’s page, optionally pinned to a single state. Embeds record no telemetry at all: a person using the calculator on a third-party page never visited us and never saw our privacy page, so counting them would mean collecting data from people who did not come here.

Results can be shared, and the link stays correct
A share link carries the inputs rather than the answer, so opening it recomputes against the current tax year. A link shared in December and opened in January shows January’s tax rather than resurrecting a figure that has since changed.

No jurisdiction is left on a secondary source
Rhode Island was the last one. Its site refuses every scripted request, so the Division of Taxation’s November advisory had to be fetched through a browser session — it confirmed the Tax Year 2026 schedule exactly, and gave a head-of-household standard deduction of $16,800 that we had been filling with the single-filer $11,200. All 51 jurisdictions have now been checked against the state’s own revenue department, or are recorded with a specific unresolved discrepancy.

Arkansas, Oklahoma and Idaho corrected — three structural errors
Arkansas cut its top rate to 3.7% retroactive to 1 January 2026 and our bracket shape was wrong besides. Oklahoma consolidated six brackets into three for 2026. Idaho was carrying a 0% band to $4,811 left over from its pre-flat structure, which understated Idaho tax by about $255 for every filer; the Tax Commission states the rate is a flat 5.3% on Idaho taxable income.

State verification: 35 of 51 checked against revenue departments
Every jurisdiction has now been worked through. 35 are confirmed against the state’s own revenue department, 9 levy no wage tax, 4 have a known unresolved discrepancy and 3 could not be reached at a primary source. The live status for each, including what is still outstanding and why, is published on the methodology page. Thirteen errors were found and corrected in the process.

Hawaii standard deduction corrected for Act 46
Hawaii’s Act 46 raises the standard deduction in 2024, 2026, 2028, 2030 and 2031, and the brackets in 2025, 2027 and 2029 — the two move in alternate years. We were applying the 2024–25 deduction of $4,400 single and $8,800 joint. For tax year 2026 it is $8,000 single, $16,000 joint and $12,000 head of household, per the Department of Taxation’s own announcement of the Act.

Arizona standard deduction was roughly half the real amount
Arizona couples its standard deduction to the federal one. AZDOR publishes $15,750 single and $31,500 joint for 2025 — the federal figures — while we were applying $8,350 and $16,700. Every Arizona filer was shown too much tax, by roughly $185 a year single and $390 joint. Corrected to the federal 2026 amounts of $16,100 / $32,200 / $24,150.

West Virginia rates corrected — a 5% cut we had missed
West Virginia Code 11-21-4j cut every income tax rate by 5%, retroactive to 1 January 2026. We were carrying the 2025 rates. All five corrected: 2.22 to 2.11, 2.96 to 2.81, 3.33 to 3.16, 4.44 to 4.22 and 4.82 to 4.58, confirmed against the Tax Division’s 2026 percentage-method withholding tables.

Oregon exemption credit and Minnesota head-of-household deduction corrected
Oregon’s 2026 withholding formula gives the personal exemption credit as $263; we held the 2025 figure of $256. Minnesota publishes a head-of-household standard deduction of $23,000, which we were filling with the single-filer $15,300 — that overstated tax for Minnesota heads of household.

South Carolina rebuilt — the state replaced its whole income tax
H.4216, signed 30 March 2026 and effective for tax year 2026, scrapped South Carolina’s 0%/3%/6% graduated schedule and replaced it with 1.99% below $30,000 and 5.21% above. It also decoupled the state from the federal standard deduction, substituting the South Carolina Individual Alternative Deduction of $15,000 single, $22,500 head of household and $30,000 joint. We were still applying the old system. Confirmed against SCDOR.

Georgia rate and standard deduction corrected — a law we had missed
Georgia HB 463, signed 11 May 2026, cut the flat rate from 5.19% to 4.99% retroactive to 1 January 2026 and raised the standard deduction from $12,000/$24,000 to $15,000/$30,000. Our figures predated the law. Every Georgia page changed. Confirmed against the Georgia Department of Revenue.

Massachusetts surtax threshold and New Jersey rate corrected
The Massachusetts 4% surtax threshold is certified annually for cost of living; we held the 2025 figure of $1,083,150 and the 2026 figure is $1,107,750. Separately, New Jersey’s fourth bracket rate is 5.525% in the NJ-1040 rate schedules, not the 5.53% we had rounded it to.

California standard deduction corrected — was two years stale
Verification against the Franchise Tax Board found our California standard deduction was $5,540 single / $11,080 joint, which is the 2024 figure. The current published amount is $5,706 / $11,412. Every California page and every California figure elsewhere on the site changed as a result. The brackets and the $153 exemption credit checked out unchanged.

State figures now verified against revenue departments, one at a time
Until now our state tax tables came from a secondary compilation. Each jurisdiction is being re-checked against the state’s own revenue department, and the live status of that work — including which states are not done — is published on the methodology page. California, New York, Illinois and Pennsylvania are confirmed. New York’s rates are 0.1 point below its 2025 forms because a legislated cut takes effect for tax year 2026; that was checked rather than assumed.

First release: 12 occupations, 12 salary levels, 51 jurisdictions

Anonymous telemetry, bucketed by design
The site records which state and which salary bracket is being calculated, and nothing else. No exact salaries, no IP addresses, no identifiers, no cookies. Salaries are bucketed in the browser before they are sent, so an exact figure never exists on the server to leak.
