Data for VAT notches, voluntary registration, and bunching : theory and UK evidence Li Liu (75607) Ben Lockwood (8627094) Miguel Almunia (24856792) Eddy H. F. Tam (24932962) Value-added tax Value-added tax -- Great Britain Tax evasion Tax evasion -- Great Britain Income tax -- Great Britain -- Rates and tables Migrated from ePrints Using administrative tax records for UK businesses, we document both bunching in annual turnover below the VAT registration threshold and persistent voluntary registration by almost half of the firms below the threshold. We develop a conceptual framework that can simultaneously explain these two apparently conflicting facts. The framework also predicts that higher intermediate input shares, lower product-market competition and a lower share of business to consumer (B2C) sales lead to voluntary registration. The predictions are exactly the opposite for bunching. We test the theory using linked VAT and corporation tax records from 2004-2014, finding empirical support for these predictions.<br><br>Data record consists of a zip archive containing the relevant Stata .do files for replication and a readme file. Data analysis must be conducted on-site in the HMRC Datalab – the HMRC Datalab has standard computing facilities and Stata software for analysis. Analysis results could be released for publication, upon meeting statistical disclosure control requirement. Researchers from UK academic institution (or government department/independent research bodies) could apply to HMRC Datalab to access the data (for the CT600 data and VAT returns data). 2019-10-21T00:00:00Z Dataset Dataset 10.82444/warw.33802903.v1 https://figshare.com/articles/dataset/Data_for_VAT_notches_voluntary_registration_and_bunching_theory_and_UK_evidence/33802903 CC BY 4.0
