You may experience that the labour tax credit (arbeidskorting) and the general tax credit (algemene heffingskorting) are calculated incorrectly in a 2025 income tax return C form. Behind the calculators for tax credits on the send page, a different amount appears than expected for "vermindering vanwege beperkt/geen premie plicht". We are investigating this issue, and we will update this page as soon as more information becomes available. Our apologies for the inconvenience.
