• estimate_federal_tax≈ 863 tokens

  Use this when the user wants a rough US federal income tax figure, for example "how much federal tax on $90,000 of wages", "estimate my tax with $40,000 of freelance income", "what is my marginal rate". Pass the tax year, filing_status (single, mfj, mfs, hoh) and wages in dollars, and optionally self_employment_income, other_ordinary_income, long_term_capital_gains and adjustments. It uses the standard deduction and adds self-employment tax (with the Social Security wage base and the half-deduction), the Additional Medicare Tax and long-term capital gains rates. Returns taxable income, ordinary tax, capital gains tax, self-employment tax, total, marginal and effective rate, the assumptions made and a not_included list (credits, state tax, alternative minimum tax, itemized deductions and more). It is an estimate, not tax advice, and it is not a return.

• tax_duty≈ 1216 tokens

  Use this when a seller asks whether they must register for VAT or sales tax in a place, for example "I sell e-books from Germany and made 14,000 EUR to buyers in France, do I need to register?" or "my US company sells SaaS with 150,000 USD of sales to Texas, do I owe sales tax?". Pass seller_country, buyer_place, product_kind and yearly_sales in the money of the buyer place (leave it out when unknown); add yearly_transactions for US states that also count sales. Returns must_register (yes, no or unclear), the limit, the standard rate, the filing rhythm, where to register, the reasons, official source links with the day each was checked, and a not-tax-advice note. Covers the 27 EU states (One Stop Shop limit of 10,000 EUR), the United Kingdom and 14 US states; other places return not_covered with the covered list. It does not advise or cover sales to businesses, reduced rates, local taxes or a seller's own-country limit inside the EU, and it does not file or register anything.

  Paramètres, retour & exemple (6)

  Paramètres

  • currency · string · optionnel · EUR | GBP | USD
    Optional. The currency of yearly_sales. If it differs from the buyer place, the answer asks you to convert; it never guesses a rate.
  • buyer_place · string · requis
    Where the buyers are: an EU country code (FR, DE, EL for Greece), GB, or a US state written US-TX or by name (Texas). A bare two-letter code is a country, so CA is Canada and California is US-CA.
  • product_kind · string · requis · physical_goods | digital_products | saas
    physical_goods, digital_products (downloads such as e-books, music or apps) or saas (software used online).
  • yearly_sales · number · optionnel
    Optional. Sales to consumers in the last 12 months, in the money of the buyer place: EUR for the EU, GBP for the UK, USD for a US state. For an EU seller selling to another EU country, send the total to all other EU countries together. If the user gave no figure, leave this out (never send 0 as a stand-in): the answer then states the limit and asks for the figure.
  • seller_country · string · requis
    Where the seller is established: a two-letter country code such as DE, GB, US or VN, or the country name.
  • yearly_transactions · integer · optionnel
    Optional. Number of sales in the last 12 months. A few US states also count sales, not only dollars.
