Housing Transfer Taxes and Household Mobility: Distortion on the Housing or Labour Market?*

We estimate the effect of the UK Stamp Duty Land Tax on household mobility using micro data. Exploiting a discontinuity in the tax schedule as a quasi-experimental setting, we isolate the impact of the stamp duty from other determinants of mobility. We compare homeowners with self-assessed house values on either sides of a cut-off value where the tax rate increases from 1 to 3 percent and find that a higher stamp duty strongly negatively affects their propensity to move. The 2 percentage-point increase in the stamp duty reduces the annual rate of mobility by between 2 and 3 percentage points. This adverse effect is confined to short-distance and non-job related moves, suggesting a distortion in the housing rather than the labour market. As a cross-validation check, we also document bunching of transaction prices at the cut-off and find that the tax rate increase reduces the volume of sales by roughly
