Direct effects of illustrative tax changes bulletin (June 2025)
Updated 24 June 2025
1. Introduction
The tables below are ‘ready reckoners’, showing estimates of the effects of illustrative tax changes on tax receipts from 2026 to 2027, 2027 to 2028, and 2028 to 2029 fiscal years, based on implementation in April 2026. Illustrative changes are presented for various taxes - for example, showing the impact of a 1% or one percentage point change, assuming all other taxes and duties are unchanged. The change calculated for each tax head is detailed in each table.
Estimates are shown on a National Accounts basis, which aims to recognise tax at the time its liability arises, regardless of when the tax is received by HMRC. However, for some taxes the National Accounts basis is when HMRC receives the payment. This is due to difficulty in assessing the time at which the liability relates. Such taxes include Self-Assessment Income Tax, Inheritance Tax and Capital Gains Tax.
The figures in the table have been updated in line with the latest economy and fiscal forecasts from the Office for Budget Responsibility (OBR) published on 26 March 2025, alongside the Spring Statement 2025. Information which came to light after this date is not factored into the estimates in this publication.
Tax revenues depend on a number of key economic variables including Gross Domestic Product (GDP), prices, earnings and consumer expenditure.
The OBR’s March 2025 receipts forecast was revised downwards in the near-term and upwards in the medium-term, relative to their October 2024 forecast. This revision reflected a downward revision to the underlying forecast, offset by the upward impact of policy measures announced at the Spring Statement 2025.
It is important to note that the estimated impacts of the illustrative policy changes presented in the bulletin are reliant on the OBR’s March 2025 economic forecasts and are therefore sensitive to changes in the economic outlook. The estimates do not include any economic or policy changes made since the Spring Statement on 26th March 2025.
2. Methodology
Unless otherwise stated, the costs of the effects are estimated using standard HMRC models and methodologies.
All estimates show the impacts of the various illustrative changes on top of what is already assumed in the indexed baseline – this is generally revaluation based on latest available data, plus any previous announcements on rates and allowances up to and including the Spring Statement 2025. The changes are applied from April 2026.
The estimates only consider the direct impact of a measure on the tax base to which it is being applied, or to closely related tax bases. Generally, we do not consider effects on other tax bases and wider economic factors, such as inflation and investment, as these are usually captured in the OBR’s economy forecast.
Unless otherwise stated, the effects of the illustrative changes can be scaled up or down to provide a rough guide to the potential effects. A reduction of 2p in a tax rate will cost around twice as much as a reduction of 1p. However, the costs of increasing an Income Tax allowance or rate limit do not scale so linearly. Typically, the additional cost falls as the allowance or rate limit rises. We therefore provide estimates for different percentage increases and decreases for the main Income Tax allowance and limits. The illustrative figures for Capital Gains Tax rates are also non-linear and so cannot be scaled up, therefore, we have provided estimates for multiple percentage point increases for the Capital Gains Tax rates.
The total cost of a group of changes can broadly be assessed by adding together the estimated revenue effects of each change. However, if for example, Income Tax allowances are increased substantially and combined with a reduction in the basic or higher rate, the cost of the rate reductions will be reduced. In such cases, the cost or yield obtained by adding components from the ready reckoner should be considered only as a general guide.

5. Income Tax rates
Illustrative tax changes | Current Estimate, financial year 2026 to 2027,£ million | Current Estimate, financial year 2027 to 2028,£ million | Current Estimate, financial year 2028 to 2029,£ million | Note |
---|---|---|---|---|
Change starting rate for savings income by 1p | 0 | 10 | 5 | 1, 2, 3 |
Change basic rate by 1p | 6900 | 8250 | 8200 | 1, 2, 3 |
Change higher rate by 1p | 1600 | 2150 | 2100 | 1, 2, 3 |
Increase additional rate by 1p (yield) | 145 | 265 | 230 | 1, 2, 3, 4 |
Decrease additional rate by 1p (cost) | 175 | 335 | 300 | 1, 2, 3, 4 |
Notes:
(1) The illustrative figures for Income Tax (apart from those exclusively for savings or dividends income) show the exchequer impact on the UK government (this is. the impact on Income Tax revenues from England and Northern Ireland, plus any associated changes in the Scottish Government’s and Welsh Government’s block grants). The ready reckoner does not include any impacts of changes for the elements of Income Tax devolved for Scotland or Wales.
(2) The illustrative figure for changing the starting rate of Income Tax by 1p assumes a minimum savings allowance of 20%.
(3) The illustrative figures account for taxpayers’ behavioural responses, estimated by applying taxable income elasticities and by considering the impact on tax motivated incorporations. There is significant uncertainty around these modelling assumptions, particularly concerning rate changes to the Income Tax and National Insurance Contributions of Additional Rate taxpayers.
(4) The illustrative figures for changing the Additional Rate of Income Tax include impacts due to taxes on carried interest in 2026 to 2027 and 2027 to 2028. Carried interest will be taxed within the Income Tax framework from April 2026, as announced in the Autumn Budget 2024.
6. Income Tax allowances and reliefs

9. National Insurance contributions rates
Illustrative tax changes | Current Estimate, financial year 2026 to 2027,£ million | Current Estimate, financial year 2027 to 2028,£ million | Current Estimate, financial year 2028 to 2029,£ million | Note |
---|---|---|---|---|
Change Class 1 employee main rate by 1 percentage point | 5350 | 5300 | 5400 | 5, 6, 8 |
Change Class 1 employee additional rate by 1 percentage point | 2000 | 2000 | 2050 | 5, 6, 8 |
Change Class 1 employer rate by 1 percentage point | 11150 | 11250 | 11550 | 6, 7, 8 |
Change Class 4 main rate by 1 percentage point | 440 | 525 | 445 | 5, 8 |
Change Class 4 additional rate by 1 percentage point | 295 | 355 | 320 | 5, 8 |
Notes:
(5) Behavioural effects are included in these illustrative figures where appropriate, estimated by applying taxable income elasticities and by considering the impact on tax motivated incorporations. The approach taken to produce these estimates differs from the methodology used by the Office for Budget Responsibility (OBR) at Spring Budget 2024 for the two percentage point cuts in Class 1 and 4 National Insurance Contributions and presented in their Economic and Fiscal Outlook for March 2024. This is due to the OBR applying labour market impacts instead of taxable income elasticities at that event. There is a degree of overlap between taxable income elasticities and labour supply elasticities, with the OBR’s decision to use the latter in this instance being a pragmatic one. More information about the OBR costing methodology for the NICs cuts announced at Autumn Budget 2023 and Spring Budget 2024 is available on the OBR’s website. There is significant uncertainty around these modelling assumptions.
(6) The illustrative figures include Class 1A and Class 1B National Insurance paid by employers.
(7) A change to the rate of Class 1 employer National Insurance contributions (NICs) would have substantial additional negative exchequer effects from earnings and business profits depending on the assumed incidence of an employer rate increase. These judgements are made by the Office for Budget Responsibility with the effects captured in their economic and fiscal forecasts. These effects are not captured here, but the impact of the NIC changes announced at Autumn Budget 2024 is available on the OBR’s website. There is significant uncertainty around these modelling assumptions.
(8) This publication no longer includes an estimate for changing Class 2 NICs amounts, following the Government’s Autumn Statement 2023 announcement that the self-employed will no longer have to pay Class 2 from April 2024 onwards.

12. Corporation tax
Illustrative tax changes | Current Estimate, financial year 2026 to 2027,£ million | Current Estimate, financial year 2027 to 2028,£ million | Current Estimate, financial year 2028 to 2029,£ million | Note |
---|---|---|---|---|
Increase Corporation tax by 1 percentage point | 3600 | 3900 | 4000 | 12 |
Notes:
(12) This estimate represents a 1 percentage point change to the main rate and small profits rate for onshore Corporation tax; it does not include offshore Corporation tax for North Sea oil and gas companies, Energy Profits Levy, Bank Surcharge nor Residential Property Developer Tax, which are separate profits-based taxes. Corporation tax is presented as ‘time-adjusted cash’, in line with the way the Office for National Statistics reports these revenues in the Public Sector Finances. The methodology for calculating time-adjusted cash aligns receipts more closely to the period of the economic activity that generates the tax liability.
13. Capital Gains Tax

Increase Annual Exempt Amount by £500 for individuals and £250 for trusts | 0 | -35 | -30 | 13, 15 |
Notes:
(13) Estimates have been revised in line with updates to the Capital Gains Tax forecast and key economic variables. All estimates include behavioural impacts on Capital Gains Tax, Income Tax and Stamp Duty Land Tax. Capital Gains Tax behavioural estimates are based on a CGT elasticity estimated on HMRC data. The baseline for these estimates includes all measures that have been announced and will be in effect over the period of estimation. This includes changes to Capital Gains Tax rates announced at Autumn Budget 2024. Capital Gains Tax lower and higher rates include changes to both the residential property and the main rates. Capital Gains Tax on Carried interest is no longer included in these estimates as it is now included in the Income Tax estimates from 2026 to 2027.
(14) Please note that these rate changes are non-linear and asymmetrical. For example, doubling the change in revenue from a 5-percentage-point increase does not accurately predict the change in revenue under a 10-percentage-point increase. Very large tax rate rises can reduce exchequer yield due to taxpayer behavioural impacts.
(15) The illustrative tax changes for CGT includes a number of different effects which occur at different points of the estimation period. For example, an increase in the Residential Property higher rate can lower Capital Gains Tax disposals and Stamp Duty Land Tax revenue which are largely scored in the same year as they happen, whereas increases to the main rates of Capital Gains Tax have effects on Capital Gains Tax and Income Tax that largely lag a year due to Self-Assessment tax returns. Depending on the strength of the loss or yield from each tax head in each year we may see a net loss to the exchequer in some years and a net revenue gain in other years. Negative signs are used in the CGT illustrative tax changes to indicate net losses.
14. Inheritance tax
Illustrative tax changes | Current Estimate, financial year 2026 to 2027,£ million | Current Estimate, financial year 2027 to 2028,£ million | Current Estimate, financial year 2028 to 2029,£ million | Note |
---|---|---|---|---|
Increase standard rate for estates left on death by 1 percentage point | 105 | 240 | 290 | 16, 17 |
Increase Nil Rate Band by £5,000 (cost) | 60 | 140 | 165 | 16 |
Increase Residence Nil Rate Band by £5,000 (cost) | 25 | 55 | 65 | 16 |
Notes:
(16) Due to the six-month lag between the date of death and when Inheritance Tax becomes due, receipts in the first year of the policy change will be lower than in subsequent years.
(17) Increase to main rate and reduced rate of Inheritance Tax.

Landfill tax | Tonne of waste: £4.05 | neg | neg | neg | 25, 26 |
Notes:
(18) All illustrative impacts to alcohol rates are based on the alcohol taxation regime implemented from August 2023. To align with other estimates in this publication all rate changes are assumed to take effect from 6th April each year. In practice, as announced at Autumn Budget 2024, the OBR’s forecast assumes that alcohol duties will be uprated on 1st February each year from 2025 onwards.
(19) Beer and cider: the illustrative revenue figures are based on duty increases on all beer, all still cider and sparkling cider with an ABV (alcohol by volume) below 5.5%. The strength of a typical pint of beer is assumed to be 4.5% ABV (rounded to 1 d.p.). The amount of duty paid on a pint of beer reflects rates for an off-trade product. Draught beer faces a lower rate since 1st August 2023, with the duty on a pint of 4.5% ABV (1 d.p.) beer being 48p. The alcohol duty paid on a drink is relative to its alcoholic strength, so exact rates will vary based on ABV.
(20) Wine and other fermented product: the illustrative revenue figures are based on duty increases on all wine and other fermented products, as well as sparkling cider from 5.5% to 8.5% ABV. The strength of a typical bottle of wine is assumed to be 11.7% ABV (1 d.p.). The alcohol duty paid on a drink is relative to the alcoholic strength of the drink, so exact rates will vary based on ABV.
(21) Spirits: the strength of a typical bottle of high-strength spirit is assumed to be 41.7% ABV (1 d.p.). The alcohol duty paid on a drink is relative to its alcoholic strength, so exact rates will vary based on ABV.
(22) Duty on cigarettes has specific and ad valorem elements. As the duty paid on cigarettes is relative to their price, the exact duty on a pack is variable. The indicative duty figure is based on the weighted average price (WAP) in 2025 and current duty rates. A 1% change in specific duty rate is applied to all tobacco products and is also applied to the Minimum Excise Tax for cigarettes. The tobacco duty change estimated here is assumed to occur in Autumn 2026 which leads to a smaller revenue figure in 2026 to 2027 as the ready reckoned rate only affects part of this year.
(23) As a result of the October 2026 introduction of Vaping Products Duty, from this date the tobacco duty illustrative figures also show the exchequer impact of tobacco duty changes on vaping duty receipts through substitution effects.
(24) The 2026 to 2027 figures have been calculated by adding 5 pence to the 2025 to 2026 ready reckoned duty rate and then uprated by forecast RPI+1% (to incorporate the ready reckoner). This reflects the expiry of the 5p cut in April 2026 assumed in the baseline. The 2027 to 2028 and 2028 to 2029 duty rates has been calculated by uprating the previous year’s duty rate by forecast RPI.
(25) The indicative level of current duty on a typical item for the Aggregates Levy and the Landfill Tax reflect rates from 1 April 2025.
(26) Landfill Tax (LFT) has been devolved to Scotland and Wales. The estimates shown relate to England and Northern Ireland only.
16. Vehicle excise duty

Increase rates by £1 for motorbikes and £5 for all other vehicles | 205 | 210 | 215 | 27 |
Notes:
(27) The 2026 to 2027 figure represents the revenue raised as a result of increasing all VED rates for 2025 to 2026 by £5, other than motorbikes, which were increased by £1. This increased rate then affects rates from 2027 to 2028 and beyond, as they are increased by forecast RPI. Rates are rounded as standard.
17. Air passenger duty

---|---|---|---|---|
Increase reduced rate by £1 | 115 | 125 | 130 | 28 |
Notes:
(28) The 2026 to 2027 figure represents the revenue raised as a result of increasing reduced APD rates for 2025 to 2026 by £1. This then affects 2027 to 2028 reduced rates, which have been increased above RPI inflation. In addition, APD rates from 2027 to 2028 onwards are rounded to the nearest penny.

(30) The residential nil-rate band reverted to £125,000 (£300,000 for First-Time Buyers) and the First-Time Buyers’ Relief eligibility cap reverted to £500,000 for 2025 to 2026 onwards.
(31) This also includes the cost from the same change made to the rate paid by First-Time Buyers purchasing a property for a price between £300,000 and £500,000.
(32) Please note that these rate changes are non-linear and asymmetrical. For example, doubling the change in revenue from a 1-percentage-point increase does not accurately predict the change in revenue under a 2-percentage-point increase. Some tax rate rises at higher rates can reduce exchequer yield due to taxpayer behavioural impacts.
(33) Please note that negative values for costs indicate net yield and negative values for yields are a net costs.
(34) ‘Non-residential’ rates were previously labelled ‘commercial’ but have been renamed to align labels used across publications. Note that non-residential SDLT is different from NRSDLT, which is SDLT paid by non-residents on residential transactions.
