TaxTools Network Tax Facts

TaxTools Network Tax Facts serves a curated set of tax figures and rules for the United States, the United Kingdom, Canada, Australia and New Zealand: rates, thresholds, caps, allowances, credits, deadlines and the conditions that go with them, about 9,800 facts in all.

Every fact comes with the official source it was taken from: the page or legal instrument's URL, a quote of its own words, the type of source (statute, regulation, agency guidance), the date it was last verified, and when it is next due for review. Answers can therefore cite the government body directly instead of relying on memory.

Four read-only tools:

• find_tax_facts: search one country's facts by words, optionally for one tax year.
• get_tax_fact: one fact in full, with its source, quote, verification date and review date.
• check_tax_claim: check a statement against wrong versions of a rule that have been recorded and corrected. It reports a contradiction with the correct fact, or that none is known; it never confirms a statement as correct.
• get_upcoming_changes: facts due for review in a date window, grouped by the release that moves them or by month.

Each answer says whether a fact is current or past its review date, whether a figure is official, projected, carried forward or derived, and when a later tax year exists. When nothing matches, the server says so rather than returning a nearby figure.

No account or sign-in is needed. The server receives only each tool's inputs, never the conversation. Answers are general information, not tax advice.
