rompbelasting

Rompbelasting is a term used in Dutch-language policy discussions to describe a hypothetical tax design intended to tax the core economic base of households or firms—the metaphorical “torso” of wealth and income. It is not an officially implemented policy but rather a concept used in academic exercises and think-tank debates to explore how a simple, broadly based levy might interact with equity and efficiency.

Etymology: The word combines romp (torso) with belasting (tax).

Concept: The idea centers on taxing the central sources of economic capacity, such as primary labor income and core profits, while allowing exemptions or lighter treatment for peripheral income or non-core assets. Proposed bases are typically paired with progressive rates and are envisioned to be administratively simpler than some existing tax structures. The rompbelasting is often framed as a complement to current taxes rather than a replacement.

Variants: In discussions, there are differences in scope—some proposals apply to individuals focusing on labor and core capital, others to firms focusing on core profits. Definitions of what constitutes the core base vary, as do proposals for single-rate versus multi-rate structures.

Administration and effects: Supporters stress potential transparency and broad tax capacity; critics point to definitional ambiguity and opportunities for avoidance or manipulation. Debates continue about impacts on work effort, savings, investment, and overall growth.

Relation to existing taxes: The term is not a formal category in Dutch tax law and is treated as a theoretical construct in contrast to established taxes such as income tax, wealth tax, corporate tax, and consumption taxes.
