Second estimate of the VAT gap (tax year 2022 to 2023)

Updated 30 October 2024

An Official Statistics release. Published 6 March 2024.

1. What is the VAT gap?

The VAT gap is measured by comparing the net VAT total theoretical liability (VTTL) with actual receipts (this is comparing the amount of VAT HMRC expects to receive and the VAT HMRC actually receives). The VAT gap methodology uses a ‘top-down’ approach.

2. Second estimate of the VAT gap for tax year 2022 to 2023

The table below shows the headline figures used to produce the second VAT gap estimate for tax year 2022 to 2023

Financial year	Net VAT total theoretical liability	HMRC net VAT receipts	Net VAT receipts related to net VAT total theoretical liability in 2022 to 2023	VAT gap (point estimate)	VAT gap (per cent)
2022 to 2023	£166.7 billion	£159.7 billion	£158.1 billion	£8.6 billion	5.2

The amounts calculated are rounded to the nearest £0.1 billion and the VAT gap as a percentage has been rounded to the nearest 0.1 per cent. Net VTTL and net VAT receipts are expressed net of payments and repayments. A portion of the VTTL estimate is projected rather than actual expenditure.

The second estimate of the VAT gap for 2022 to 2023 at 5.2% (£8.6 billion) is a slight reduction in percentage terms compared with the estimate of the VAT gap for 2021 to 2022 of 5.4% (£7.6 billion) published in ‘Measuring tax gaps 2023 edition’. It is also a slight increase on the 2020 to 2021 estimate of 5.0% (£6.3 billion), in the same publication.

There has been a downward revision of 0.1 percentage points to the second estimate of the VAT gap for 2022 to 2023 compared with the preliminary estimate (previously 5.3%). This represents a £0.2 billion downward revision to the VAT gap from the preliminary estimate (previously £8.8 billion). The small revision is net of a correction to the VTTL for a modelling error identified since the preliminary estimate to account for the the temporary reduction to VAT to 12.5% for hospitality and cultural attractions in the last three months of 2021 to 2022. Other updates include incorporation of the latest ONS Blue Book and Consumer Trends data.

As per the preliminary estimate, the estimates here include adjusting for the Energy Bills Support scheme, for Postponed VAT Accounting Policy, and residual impacts related to deferred VAT between March 2020 and June 2020 under the ‘VAT payments deferral scheme’ and ‘VAT Deferral New Payment Scheme’ - key fiscal support measures in the government’s response to Covid-19.

Taken together, these adjustments to VAT receipts ensure when estimating the VAT gap for 2022 to 2023 that only the net VAT receipts which related to the net VAT total theoretical liability (net VTTL) in 2022 to 2023 are properly taken into account (this figure is shown in a separate column in table above, ‘Net VAT receipts related to net VAT total theoretical liability in 2022 to 2023’).

3. Details of HMRC’s VAT gap publications

HMRC publishes three estimates of the VAT gap for the latest tax year (2022 to 2023): the first in the autumn, the second at spring, and the third as part of HMRC’s ‘Measuring tax gaps’ publication in the summer.

The preliminary estimate of the VAT gap for 2022 to 2023 was published at Autumn Statement 2023. It is based on a full year of household expenditure data in line with ONS Consumer Trends data up to and including 2022 quarter 3 - which accounts for around 70% of the VTTL. The remaining 30% of the VTTL, comprising government, charities, businesses making non-business or supplies exempt from VAT, and housing, was based on ONS National Accounts Blue Book 2022 non-household data and a forecast produced by the Office for Budget Responsibility (OBR).

This is the second estimate of the VAT gap for 2022 to 2023 at Spring Budget 2024 and it includes the latest ONS Consumer Trends data for 2023 quarter 3. It also includes the latest ONS National Accounts Blue Book 2023 non-household expenditure data but continues to forecast around 30% of the 2022 to 2023 VTTL in line with the latest OBR forecasting assumptions.

The third VAT gap estimate for 2022 to 2023 will be published along with an updated historical series as part of the ‘Measuring tax gaps 2024 edition’ publication in summer 2024. It is expected to include further updates, such as ONS Consumer Trends data.

Due to timing, the ‘Measuring tax gaps 2024 edition’ publication will not include the Blue Book 2024 data, therefore 30% of the 2022 to 2023 estimate will remain forecasted until the publication of ‘Measuring tax gaps 2025 edition’.
