Tax data changes.    
Experience tree bears fruit.    
Measurement improves.    

Accounts information that businesses supply to Inland Revenue for tax purposes provide over 96% of the observations in the productivity dataset in the Longitudinal Business Database. In 2013, material changes in the data collected halted the annual updating of the productivity dataset. This paper describes a method for accounting for these raw data discontinuities, and revisits the prior productivity dataset methodology, implementing wholesale changes that improve the overall quality of the data and the versatility of the productivity dataset.
