Projects on this term

The score comes from our model.

• Show HN: A proof-of-concept formalization of the IRS federal tax forms · score 7.0

  This project formalizes the IRS federal tax forms as machine-checkable data with per-line citations, a closed vocabulary of arithmetic atoms, a type checker, a Lean specification and reference evaluator, and differential testing against external tax engines. It is a rigorous exercise in reproducibility and validation, but its practical utility is limited because it only covers a narrow slice of individual tax preparation and is not a filing system.

• Show HN: OpenTaxRate – open-source US sales tax rates by street address · score 6.8

  OpenTaxRate is a self-hostable TypeScript API that resolves combined US sales tax rates by street address and date, combining address ranges, PostGIS tax boundaries, and dated rates with explicit 422 declines for ambiguous lookups. It stands out for its verifiability — published sources, benchmarks, and a refusal to guess — filling a niche currently served by expensive compliance vendors.

• Show HN: iOS location based traveler's currency conversion with tax estimations · score 5.3

  SmarterCurrency is an iOS app that converts prices to the traveler's home currency and estimates final costs by incorporating local sales tax and tipping customs based on location. It addresses a common pain point for travelers in countries like the US and Canada where displayed prices exclude tax, offering a more accurate budgeting tool.

• Show HN: Tax Map – Explore property tax scenarios across England · score 5.0

  Tax Map is an interactive visualization tool that lets users explore hypothetical property tax reforms across England, comparing current Council Tax with a proposed annual property tax. It uses official data and an offline Python pipeline to generate estimates, presented via a SvelteKit and MapLibre frontend.
