Official tax data sources

Production tax rules come only from government agencies. Competitor calculators, blogs, AI answers, and screenshots are never accepted as tax-rate sources.

Ohio local data

The static Ohio selector contains the municipality, JEDD/JEDZ, and school district records active on July 15, 2026 from the Ohio Department of Taxation’s Finder downloads. The source files remain part of the review trail and are compiled at build time; the calculator never sends an address to The Finder.

Pennsylvania local data

Pennsylvania work and residence selectors use all 2,619 unique PSD records in DCED’s official 2026 EIT/PIT/LST register. Eight duplicate rows for municipalities spanning county boundaries are consolidated only after their tax fields are verified as identical. Three July 1 DCED EIT starts and Philadelphia’s July 1 rate reduction are selected by paycheck date. The static register loads only on the Pennsylvania calculator and does not contain or transmit a street address.

Delaware local data

Wilmington's current City Code imposes 1.25% on resident earned income and on nonresident compensation for work in the city. WageFrame asks for work and residence city status separately, applies the tax once when either fact triggers it, and leaves the estimate partial when the location is unresolved. Multi-location wage allocation and a later nonresident refund are outside this release.

Maintenance policy

A weekly monitor checks source availability and content hashes. A change creates a review alert only—it never silently replaces production tax rules. A reviewer confirms effective dates, tables, caps, and official examples before issuing a new dataset version.

Partial and unavailable coverage

Alabama local occupational taxes, Kentucky local occupational taxes, and West Virginia municipal service fees do not have a complete current official statewide payroll inventory. Their state methods are published only as forced-partial estimates with those local layers omitted. The Washington, D.C. employee method is unavailable, so WageFrame publishes no D.C. numeric result.
