From October 2014 around 24 million people will receive the statement compared to 20 million established in the 2012 Budget.
Osborne said: “These tax statements represent a huge boost for tax transparency, showing people very clearly how much tax they pay and giving them a better understanding of where their money is spent.”
Statements detail how income tax and National Insurance contributions have been calculated, the average tax rates and public expenditure.
The additional four million people are pay-as-you-earn taxpayers who might be experiencing unusual or changing circumstances such as a new job.
Any taxpayer who does not receive a tax statement can use HMRC’s tax calculator app to estimate their tax bill and see how it contributes to public spending.
