Abstract Although research highlights the discipline‐enhancing effect of fiscal rules at the national level, little is known about their impact on local budgets. We employ a dynamic fiscal reaction function within an LSDVC framework to explore the relevance of different local fiscal rules in the EU using a panel dataset of 26 European countries over a 26‐year period (1997–2022). Our findings suggest that debt rules and expenditure rules have a positive relation with budget discipline on the local level. Thus, the mere existence of a DR is less relevant compared to its strength. Consequently, rule design should receive greater attention.
