Tax rates change, wage data is revised, and errors get fixed. Every one of those is recorded here with a date, because a calculator that quietly changes its answers is not one you should trust.

The site said local taxes were not included, a month after they were
The homepage, the methodology page and llms.txt all still read “local income taxes are not included”, although New York City, Yonkers, Philadelphia, every Maryland and Indiana county, 17 Ohio cities, Kansas City, St. Louis and Detroit had been selectable since August. The description is now generated from the engine’s own list, and a new page, /local-taxes, prints every modelled locality with its rate and what a $75,000 salary owes there.

Seven states corrected after re-reading every state’s own documents
Oklahoma’s 2026 brackets were not the ones HB 2764 enacted (0% to $3,750, 2.5% to $4,900, 3.5% to $7,200, 4.5% above) and tax was overstated by $63.75 single and $127.50 joint. Wisconsin’s standard deduction falls with income — $7,374 at $75,000, not the full $13,960 — so tax was understated by $349. Alabama now deducts federal income tax paid, steps its standard deduction down with income as the Form 40 chart does, and gives heads of family the $3,000 exemption. Hawaii and Maryland now use their head-of-household schedules, Louisiana gives heads of household the joint deduction, and Kansas adds their extra $2,320 exemption. Single and joint figures in Hawaii, Kansas, Louisiana and Maryland did not change.

Ohio city income tax — the 17 largest municipalities
Ohio cities tax qualifying wages from the first dollar: no bracket, no standard deduction, no exemption, and 401(k) deferrals are NOT exempt. So a Columbus resident on $75,000 owes $1,875 to the city on top of $1,287 to the state — and someone on $20,000 owes the city $500 while owing the state nothing at all. Seventeen cities are now selectable, from Cincinnati at 1.80% to Euclid at 2.85%. Each rate was read individually from The Finder, the Department of Taxation’s own address lookup, because Ohio retired its bulk rate table when it rebuilt that tool in July 2026 and roughly 580 smaller municipalities remain out of scope.

State payroll deductions now modelled — California SDI was the biggest single omission on the site
Three states were materially wrong for every worker in them, and California was the worst: SDI is 1.3% of every dollar earned with NO wage cap since SB 951 took effect in 2024, so a $100,000 salary was overstated by $1,300 a year and a $500,000 salary by $6,500. New Jersey deducts unemployment, workforce, disability and family-leave contributions on TWO different wage bases — $44,800 for the first two, $171,100 for the worker side of the last two — worth $505 at $75,000. Both now appear as their own line, because they are neither income tax nor FICA. Oregon was wrong in the other direction: it lets you subtract the federal tax you paid, capped at $8,750 and phased to zero between $125,000 and $145,000 of income, which we had never applied — Oregon tax was overstated by up to about $800.

Local taxes, phase 1: New York City, Yonkers, Philadelphia, and all of Maryland
The largest systematic overstatement on the site is gone for the places it was largest. A city/county selector now appears for New York, Pennsylvania and Maryland — opt-in, because the calculator never guesses where inside a state someone lives. Five mechanically different structures are modelled, because conflating them produces plausible wrong numbers: NYC is progressive brackets on state taxable income (every printed IT-201 base amount is reproduced as a test); Yonkers is 16.75% of the state tax itself, not of income; Philadelphia is a flat wage tax that 401(k) deferrals cannot escape, blended across the two fiscal-year rates that span 2026; Maryland counties are flat on taxable income — except Anne Arundel, which is genuinely progressive, and Frederick, where one rate chosen by income level applies to the whole of it. Every figure is from the state or city’s own publication, and the API accepts &locality=.

Ohio and Arkansas structural gaps closed — one state left unresolved
The engine can now express two structures it previously could not. Ohio tiers its personal exemption by income — $2,400 to $40,000 of MAGI, $2,150 to $80,000, $1,900 to $500,000, and nothing above that from 2026 — where we applied a flat $2,400 to everyone. Arkansas publishes two bracket tables selected by income: above $94,700 of net taxable income the engine now switches to the high table, whose ~$287 jump at the boundary is the state clawing back low-bracket savings by design; that figure is verified by arithmetic identity and held as a test. Of 51 jurisdictions, 50 are now settled against primary sources; Wisconsin remains the one open item, because it has not published its 2026 figures in any retrievable form.

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.

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.

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.

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.

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.
