I build tools that answer money questions people cannot answer for themselves. Estimate Tax exists because the calculators already out there share a habit that bothered me: they present a number without telling you where it came from, and a surprising share of those numbers are wrong.
My background is SEO and content in finance and economics, and my own interest runs to blockchain and financial software — the part of it that is about making an opaque system legible rather than about speculation. That is the same instinct behind this site.
Everything here is calculated deterministically and checked against the source that sets the rule: the IRS for federal figures, each state’s own department of revenue for state ones, and the US Census Bureau for county property data. Where a figure could not be verified, the page says so rather than filling the gap.
The work, in numbers
Federal, FICA and every state's own rules for 2026.
Read off that state’s own department of revenue, not a compiled table.
Errors in the compiled sources the whole category relies on.
US Census ACS, one figure per county rather than a state average.
Homestead exemptions, assessment caps and ratios, all read at source.
Where a figure could not be verified, the page says so.
What “checked” means here
Financial sites usually mark a page with a fact-checked badge and leave it there. This site does something narrower and more useful: for every state, it names the document that was read, the date it was read, and what the reading found. That log is public, and it includes the failures.
Of the 37 states checked so far, 12 carried a figure that was simply wrong in the compiled sources this whole category relies on. Ohio was the worst: the source treated it as a flat rate from the first dollar and missed the band it does not tax at all, overstating the bill by 43%. South Carolina had been rebuilt by a law signed in March 2026. Georgia’s rate had been cut in May and backdated.
The log also records the times I got it wrong and had to retract — an alarm raised over New York that turned out to be my own misreading, and an Oregon credit this site was publishing at nearly double its real value until the state’s own page corrected me. A log that only contains successes is not a log.
What this site will not do
- It does not give tax advice.These are estimates for planning. Filing decisions belong with a professional who knows your situation.
- It does not guess.Where a figure could not be read at source — 4 cases so far — the page says so instead of filling the gap with something plausible.
- It does not keep your numbers.The calculations run in your browser. Nothing you type is sent anywhere or stored.
- It does not invent a review board.One person writes and maintains this. Claiming a second reviewer to look more authoritative would be a lie, and an easy one to tell.
Tax figures change mid-year and states backdate them. If a number here does not match what your state publishes, that is worth knowing — get in touch through LinkedIn and it gets checked against the source and corrected in the log, with the correction attributed.
