tax_rate_as_of | Look up the GST/VAT standard rate that applied in a country ON A GIVEN DATE, rather than today's rate. Use it when reconciling or amending a past transaction, invoice or return — several countries changed rate recently (Estonia twice since 2024, Finland, Kazakhstan, Russia, Romania, Slovakia, Ghana, Israel, Ecuador), so the rate today is not the rate that applied then. For the current rate use tax params: country*, date* |
tax_rate_lookup | Look up one country's headline tax rates: GST/VAT standard and reduced rates, top personal income tax rate, and company tax rate — national rates for 193 countries, plus state and provincial sales tax for CA and US when you pass region. Use it for a single country; to see several countries side by side use compare_countries, and to apply GST/VAT to an amount use compute_gst_vat. Rates come from a params: country*, region |
compute_gst_vat | Add or remove a country's GST/VAT — or its other national consumption tax, such as Japan's consumption tax or Malaysia's SST — on a monetary amount, returning the net / tax / gross split. Use it to convert between tax-exclusive and tax-inclusive prices (invoices, quotes, receipts); for the rates themselves use tax_rate_lookup. Pure arithmetic on the current standard rate, rounded to 2 decimals, in params: country*, amount*, mode, region |
compare_countries | Compare headline tax rates — GST/VAT, top personal income tax and company tax — across several countries at once. Use it to shortlist or contrast jurisdictions (relocation, expansion, pricing); for one country's full detail use tax_rate_lookup, and to apply a rate to an amount use compute_gst_vat. Pass income to add, per country, the income_tax_estimate result for that income (income tax, total ta params: countries*, income, taxYear |
income_tax_estimate | Estimate personal income tax and take-home pay from gross annual income for 57 countries, using the engine's effective-dated brackets with each country's own levies, offsets and social contributions as its scheme defines them.

company_tax_estimate | Estimate company/corporate income tax on an annual profit at the headline rate for 139 countries (28 verified against the national authority; the rest are indicative OECD headline rates, and the answer says "not verified — confirm with" the authority). Use it for company profit questions; individuals belong to income_tax_estimate. smallBusiness applies the small-company rate only where it covers a params: country*, profit*, smallBusiness |
cgt_estimate | Estimate capital gains tax on one sale of shares or property by a resident individual, for 71 countries (AE, AR, AT, AU, BE, BG, BR, CA, CH, CL, CN, CO, CY, CZ, DE, DK, EE, EG, ES, FI, FR, GB, GH, GR, GT, HK, HR, HU, ID, IE, IL, IN, IS, IT, JM, JP, KE, KR, LI, LK, LT, LU, LV, MT, MU, MX, MY, NG, NL, NO, NZ, PH, PK, PL, PT, QA, RO, RS, RU, SA, SE, SG, SI, SK, TR, TW, TZ, UA, UG, US, ZA).

student_loan_repayment | Estimate the compulsory annual study or training loan repayment (HELP, HECS, VSL, SFSS, SSL, AASL) for an Australian resident from their repayment income, using the marginal system introduced in 2025-26 with effective-dated thresholds that roll over each financial year. Use it for "how much HELP/HECS will I repay" questions in AU; it does not cover the loan balance, indexation or voluntary repayme params: repaymentIncome*, taxYear |
superannuation_estimate | Estimate Australian superannuation for an employee: the compulsory Superannuation Guarantee contribution (12% from 2025-26), concessional (before-tax) contributions cap usage, the 15% in-fund contributions tax, and the Division 293 high-earner surcharge — all effective-dated so a future budget year is picked automatically. Use it for "how much super will I get / can I contribute / will I be taxed" params: ordinaryEarnings*, salarySacrifice, personalDeductible, otherTaxableIncome, taxYear |
tax_facts | Sourced facts about a country's tax system: when and why its GST/VAT was introduced, what it replaced, and memorable, true stories (court cases, elections, odd rulings) — each fact linked to its own source. Omit country for a primer on what a consumption tax is plus famous tax stories from history. Pass topic to keep only facts about one tax (each fact lists its topics). Use it for background, exp params: country, topic |
