Tools

• cgt_estimate

  Estimate Australian capital gains tax for a resident individual by taxing the gain at the marginal rate on top of other income (the difference of two income-tax calculations). Use it for AU asset-sale questions (shares, property, crypto); for pay without an asset sale use income_tax_estimate — other countries' CGT is not covered and returns an error. Applies capital losses before the 50% discount for assets held over 12 months, per ATO ordering; the main-residence exemption and non-resident rules are out of scope.

• company_tax_estimate

  Estimate company/corporate income tax on an annual profit for Australia, the US, the UK, India or Canada — the five countries with source-verified company rates — applying the small-business/concessional rate where it covers all income. Use it for company profit questions in those countries; individuals belong to income_tax_estimate, and any other country’s headline rate to tax_rate_lookup. Headline-rate arithmetic only: US state tax, Canadian provincial tax, Indian surcharge/cess and UK marginal relief are flagged in the response note but not computed. A negative profit returns an explanation (losses carry forward), never a negative tax.

  shallow
• 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. Codes the dataset does not cover are reported back in unmatchedCodes rather than silently dropped; every matched row cites its national tax authority.

  shallow
• compute_gst_vat

  Add or remove a country's GST/VAT 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 country's current standard rate, rounded to 2 decimals, in the country's local currency. Countries without a single national GST/VAT (e.g. the US) return an explanatory error instead of a wrong number.

  shallow
• income_tax_estimate

  Estimate personal income tax and take-home pay for Australia, New Zealand, the UK, India or the US from gross annual income, using effective-dated brackets that roll over automatically each tax year (AU: Medicare levy + LITO; UK: National Insurance + personal-allowance taper; IN: standard deduction + s.87A rebate + surcharge + cess; US: federal FICA). Use it for individual salary and take-home questions in these five countries only — other countries return 'not available' rather than a guess; their headline consumption-tax rates live in tax_rate_lookup. This is a resident-individual estimate, not a filing calculation: it excludes state/regional taxes (UK Scotland, US state tax), non-standard deductions, and — for AU — HELP/HECS repayments (use student_loan_repayment).

  shallow
• 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 repayments, and applies to Australia only. Repayment income is broader than taxable income — it adds back reportable super contributions, reportable fringe benefits, net investment loss and exempt foreign income; pass that combined figure.

  shallow
• 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" questions in AU; it does not model fund fees, insurance, investment returns, non-concessional contributions or carry-forward caps, and applies to Australia only. Salary sacrifice reduces salary; a personal deductible contribution is a deduction against total assessable income. Both add to the concessional total. The Division 293 threshold is tested against taxable income plus LOW-TAX contributions — that is, concessional contributions excluding any excess over the cap, since the excess is already counted inside taxable income. ordinaryEarnings therefore counts toward the threshold; pass otherTaxableIncome only for income beyond salary, such as investment or business income.

  shallow
• 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_rate_lookup. The answer states plainly whether a real dated change backs it or whether only the present rate is on record.

  shallow
• 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. 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 fixed dataset verified against the national tax authority — every answer names its source and verification date, and an unsupported country returns a clear error rather than a guess.
