Open data: 2026 tax tables and rates (CSV / JSON)

The exact tables behind every paysums calculator, free to download and reuse: federal and state income tax for 2026, sales tax by state and city, VAT/GST for 38 countries, weekly mortgage rates, and the full data files for the UK, Canada, Australia, India, Germany and France. Each file names its official source and as-of year; a weekly check against those sources updates the files automatically.

Use it in articles, apps, spreadsheets or research; cite as “paysums.com, 2026 tax tables, https://paysums.com/open-data/”. The underlying figures are statutory tables and rates published by governments (US federal and state works and statutes are public domain; UK figures under the Open Government Licence; EU Commission VAT tables under CC BY 4.0), so they carry no restriction of ours. Exception: the weekly mortgage-rate file reproduces Freddie Mac PMMS averages, which Freddie Mac allows “with proper attribution” — credit Source: Freddie Mac when you use it. Nothing here is tax advice.

How the data is kept current

See the dated change log for what moved and when. Every Monday an automated check reads the official sources (IRS, SSA, each state's revenue department, HMRC, CRA, ATO, incometax.gov.in, BMF, URSSAF and DGFiP) and compares them with these files; any change is committed with its source and republished the same day. Mortgage rates come from the Freddie Mac Primary Mortgage Market Survey each Thursday. The methodology page lists what each calculator models and what it leaves out.

How the average local sales tax rates are computed

Thirty-eight states let counties, cities or districts add their own sales tax, so a single “2026 sales tax rate” for a state is really an average. Ours is computed by paysums, not copied: every incorporated city is given the local rate its state revenue department publishes for it, the unincorporated remainder of each county is given the county rate, and the rates are weighted by the Census Bureau's latest sub-county population estimates (Vintage 2025). Local rate = combined rate at the location − statutory state rate. The rate tables come from each state's official source (Streamlined Sales Tax rate files, comptroller and revenue-department downloads, county rate charts); the JSON file above names the exact file used per state. Special districts that the rate tables cannot place on the map (small transit or improvement districts) are omitted except where the state line says otherwise, so a few states run slightly below other published averages. The code is tools/localavg.py in the site's build.

Using the files

• CSV opens in Excel, Google Sheets, Numbers, pandas (pd.read_csv("https://paysums.com/open-data/files/us-state-income-tax-2026.csv")).
• JSON files are the calculators' own inputs: brackets are arrays of [upper_bound, rate] with null for the top band; std is the standard deduction by filing status.
• Need a field that is missing, or a country we don't cover yet? Tell us.
