Tax rates and allowances

Rates and allowances for taxes and benefits for 2025/26 and 2026/27 are set out in Annex A to HM Revenue & Customs, Overview of tax legislation and rates, updated 5 December 2025.

The Library publishes a short paper each year summarising rates and allowances for direct taxes (income tax, national insurance contributions, capital gains tax, and inheritance tax). The edition for the 2026/27 tax year was published on 7 April 2026.

The Budget and the Finance Bill

Each year the Chancellor of the Exchequer presents the Budget, which contains all the tax measures for the year ahead. Traditionally the Budget has been in March, before the start of the tax year on 6 April. The statutory provisions to give effect to these tax measures are set out in a single piece of legislation: the annual Finance Bill.

It has been the practice in recent years for Chancellors to make tax announcements twice a year, using the Pre-Budget Report or Autumn Statement as a second fiscal event. In November 2016 the then Chancellor Philip Hammond announced that from autumn 2017 the government would present a single autumn Budget, to allow for greater Parliamentary scrutiny of Budget measures ahead of their implementation.

Following the 2024 General Election the Chancellor Rachel Reeves presented the Labour government’s first Budget on 30 October 2024. It remains the government’s policy to have one major fiscal event a year.

The Library briefing The Budget and the annual Finance Bill provides further details.

Tax statistics

HM Revenue & Customs (HMRC) publishes data on tax receipts and taxpayers on its site.

These pages include:

Statistics on VAT, excise duties, and other indirect taxes are on this site as well. Figures on receipts from National Insurance contributions is presented separately in the annual accounts of the National Insurance Fund.

In 2010 the Office for Budget Responsibility (OBR) was established to provide independent and authoritative analysis of the UK’s public finances. The OBR’s projections for tax receipts over the next five years are in its Economic and Fiscal Outlook published in March 2026 (see Table A5: Current receipts). 

In addition to its medium-term forecasts, the OBR publishes an annual report on the main fiscal risks facing the UK and sustainability of the public finances over the long-term. The most recent edition was published in July 2026 (Fiscal Risks and Sustainability). Previously this analysis was presented in two separate reports.

As part of the data it regularly publishes, the OBR has a historical database of Budget and other fiscal event policy measures since 1970. The OBR also publishes a series of pages on individual taxes and elements of public spending.

The Library briefing Tax statistics: an overview provides an overview of tax statistics, including recent trends, forecasts, and distribution of taxpayers.
