How deep is coverage in each country?
Not every country is covered to the same depth, and we would rather tell you than pretend otherwise. TaxOrch publishes a live coverage matrix on the coverage page.
| Level | What it means | How many |
|---|---|---|
| Calculation | A exact calculator computes figures for the jurisdiction | 42 countries |
| Parameter datasets | Rates, bands and thresholds held as versioned values | 42 countries |
| Source-backed data | Tax data taken from official publishers, with citations | 128 countries |
A country can only claim what its published data supports. Each country's rates, thresholds and terms are held as sourced values, and the same checks apply to every country.
Which cross-border situations can it help with?
- Residency: which country treats you as resident, and which facts decide it.
- Foreign income: salary, freelance fees or investment income earned abroad, and where it is taxed.
- Double taxation: whether a treaty between two countries applies and how relief is usually given.
- Commerce tax: VAT or GST on cross-border sales, registration thresholds and marketplace rules.
- Federal and regional rules: national, state and regional taxes mapped together where a country has more than one layer.
Local legal terms are kept in the local language alongside the explanation, so a German or French term is recognisable when you see it on an official form.
How does it answer a question that involves two countries?
- 1Identify the jurisdictionsTaxOrch works out which countries and years the question touches.
- 2Check coverageIt confirms each country is covered deeply enough for the question.
- 3Ask for deciding factsResidency days, where work was done or where a customer is based are asked for rather than assumed.
- 4Answer with sourcesEach country's position is cited to its own official source, with any figures from a calculator.
Does it use the right year's rules in each country?
Yes. Tax years do not line up across countries: some run with the calendar year, others start in April or July. TaxOrch attaches the correct tax year to each country's part of the answer and uses the law as it stood in that year, so a question about income earned last year in two countries draws on each country's rules for its own period.
Every answer is kept in the audit log with its sources. If a rule changes after you asked, you can still see exactly what the answer was based on at the time.
