Abstract: PurposeThis study aims to examine the causal effects of England’s second-home council tax premium, effective from April 2025, on the recorded number of second homes.Design/methodology/approachUsing council taxbase returns for 2019–2025 and a panel of billing-authority adoption dates, this study applies the Callaway and Sant’Anna difference-in-differences estimator and assesses robustness to alternative estimands, spatial correlation and deviations from the parallel trends assumption.FindingsAdoption is associated with a 6.6% decline in the average recorded second-home rate among adopting authorities in the first year of charging. The estimate is stable across comparison groups and functional forms and remains robust to smooth departures from parallel trends, although it attenuates when anticipation is allowed and is not statistically significant when authorities are weighted by dwelling stock. No evidence suggests a net increase in recorded empty properties sufficient to offset the decline.Research limitations/implicationsThe evidence is limited to a single charging year and a single treated cohort. Available data cannot yet distinguish genuine change in use from reclassification onto the non-domestic self-catering base, which is identified as the priority for further work.Practical implicationsThe premium functions as a broad-based local revenue instrument. A decline in the recorded second-home count should not be interpreted as an increase in housing returning to permanent occupation, and authorities should monitor shifts between the domestic and non-domestic tax bases.Originality/valueTo the best of the author’s knowledge, this paper offers the first causal evaluation of this policy and contributes a validated adoption panel that corrects errors in official and press classifications.
