How do I choose an available calculator?

Find your country and check its availability label. An available model still has a defined employee scenario and exclusions; read the country page before calculating.

Why is a country listed if its calculator is unavailable?

Its page documents the missing rules or required inputs. Listing a country is not a promise of complete verified coverage, and missing mandatory figures do not become zero deductions.

Does an available model cover every resident?

No. Filing status, nationality, pension affiliation, region and salary limits can restrict a model. Only confirm the scenario if it matches your circumstances.

Where can I check the evidence for a country?

Available country pages include sources, scope notes and known open issues. The methodology page also brings together source references and verification gaps.

Are caveated estimates equivalent to confirmed rules?

No. Caveated calculators carry an explicit warning about unconfirmed 2026 figures. They are useful for limited planning within their stated assumptions, not as confirmed payroll or filing calculations.
