Planning estimate only, built from 2026 Belastingdienst rates. This is not a filed return or tax advice. Simplifications: AOW-age labor tax credit and pre-1946 bracket omitted; mortgage rate cap and Hillen deduction applied; DTAA relief uses a standard proportional-exemption model, not country-specific treaty text; confirm all figures with a tax adviser before filing.
