Annual Survey of Hours and Earnings linked to PAYE and Self-Assessment data – England, Scotland and Wales
This dataset links the Annual Survey of Hours and Earnings (ASHE) to Pay As You Earn (PAYE) and Self-Assessment data provided by His Majesty’s Revenue & Customs (HMRC). The linkage of ASHE with the PAYE data helps to address information gaps concerning changes in the labour market within the 12-month intervals between ASHE surveys. This has the potential to enhance our understanding of earnings and labour market transitions in Britain. Linking ASHE to PAYE and SA allows us to understand better a person’s whole interaction with the labour market.
This dataset was developed as part of the Wage and Employment Dynamics project to aid better understanding of wage inequalities in Britain.
Component datasets and linkage
The ASHE dataset includes de-identified personal information such as age, gender, employment information (such as wage and working hours), and employer information (such as the work postcode). ASHE has been linked HMRC data on earnings. The PAYE data provides details of point-in-time employment of people and what they have been paid. The Self-Assessment data provides employees’ income from self-employment and other forms of income.
|ASHE: 1997-2018. HMRC-PAYE: 2015-2019. HMRC-Self-Assessment: 2011-2018
|ASHE: Annual. HMRC-PAYE: monthly/weekly/yearly. HMRC-Self-Assessment: Annual.
|ASHE: ASHE achieved sample (approx. 0.66% of the entire workforce). HMRC-PAYE and Self-Assessment: ASHE population (1% of the entire workforce).
|England, Scotland and Wales
|ASHE: approximately 130,000 individuals observed. HMRC-PAYE and Self-Assessment: approximately 180,000 individuals observed.
Examples of research questions
- How much do self-employment and employment income substitute for each other?
- How large is the gender wage gap in all earned income?
- Is greater variation in wages through time associated with low pay?
- Is the volatility of changes in employment and/or income related to location/region?
- What are the differences in income and employment volatility between the weekly and monthly paid?
- Does having a student loan increase the likelihood of working in the gig economy?

"Linking HMRC data will provide a richer data resource that will broaden and deepen the types of labour market analysis which will be possible. In particular, linking PAYE and Self-Assessment data will: provide more timely estimates and fill in gaps on labour market transitions between ASHE survey intervals; enable a better evaluation of the impact of the minimum wage employment and earnings; provide a broader picture of an employee’s income beyond earnings; expand the view beyond employee jobs to include the self-employed, and; support the validation and calibration of earnings survey data."
