We exploit Germany's 2008/9 circulation tax reform, which generated a sharp discontinuity in annual tax liabilities at a registration cutoff date. Using administrative micro-data covering the universe of registered vehicles during the second half of 2008, we apply a difference-in-discontinuities design to estimate the effect of annual circulation taxes on permanent deregistrations. A 10 percent higher tax increases the share of deregistered vehicles after six years by about 2.8 percent. Duration analyses exploiting within-model variation in taxes yield closely consistent estimates. The effect seems to be mainly driven by exports rather than vehicle retirement.}, keywords={vehicle taxation;circulation tax;deregistrations;difference-in-discontinuities}, }
