Budget 2026: Key tax and policy insights for accountants

Chancellor John Healey has delivered the first Budget of the new government, with a strong focus on easing cost-of-living pressures, supporting small businesses, strengthening regional economies and maintaining fiscal discipline. While there were no increases to the main rates of Income Tax, VAT or employee National Insurance, the Budget contains several measures that will be relevant to accountants, businesses and advisers.

The Budget seeks to balance support for households and small businesses with the Government's commitment to fiscal responsibility. While accountants will welcome measures designed to reduce energy costs and support high streets, firms should prepare clients for continuing economic pressures and monitor forthcoming Finance Bill legislation carefully for further detail on tax measures affecting savings, investment and property income.

For accountancy firms, the Budget's long-term story is less about headline tax rates and more about digitalisation, compliance, data reporting and changes affecting business owners, investors and landlords.

From April‌‌‌ 2029, the government will introduce a new ISA to help people save for their first home. It will replace the Lifetime ISA for new accounts – existing Lifetime ISAs will continue under current rules.

Lifetime ISA withdrawals for properties above £450,000 

From 29‌‌‌ October‌‌‌ 2026, first-time buyers buying above the £450,000 cap can withdraw funds subject to a reduced 20% charge. The cap remains £450,000, and the 25% charge continues for other non-qualifying withdrawals.

Advance Tax Certainty Service

The government is reducing the minimum expenditure threshold for HMRC’s Advance Tax Certainty Service from £1 billion to £300 million, expanding access to the service from 4‌‌‌ November‌‌‌ 2026.

Stamp Duty taxes on shares – modernisation

From late‌‌‌ 2027, Securities Transfer Tax will replace Stamp Duty and Stamp Duty Reserve Tax. HMRC will test a new portal for submitting returns in‌‌‌ 2027.

From 1‌‌‌ April‌‌‌ 2027, companies will no longer need to submit a claim notification form for R&D reliefs.

Private hire vehicle operators

The government will deem the larger operators with annual fare turnover above a certain threshold are liable for 20% VAT on the full value of their fares from 2‌‌‌ January‌‌‌ 2028.

VAT treatment of cross-border services

Transformation and modernisation


Income Tax Self Assessment (ITSA) Timely Payments

From April‌‌‌ 2029, ITSA taxpayers who make Payments on Account will make smaller, more regular payments during the year they earn the income, rather than larger, infrequent amounts often many months later. Payments will be automated, for example by Direct Debit. This will help taxpayers to budget and manage their tax affairs, reduce the risk of tax debt, and move Self Assessment closer to the way many household bills already operate.

E-invoicing roadmap published

HMRC has published its roadmap for mandatory e-invoicing for VAT invoices from 2029. It explains the proposed approach and when more information will be available.

Requiring Direct Debit arrangements for VAT and PAYE return liabilities

From April‌‌‌ 2029, the government will require employers to have a Direct Debit instruction in place with HMRC for their PAYE and VAT return liabilities, while retaining flexibility to pay by other methods. Direct Debit will make it easier for customers to pay what they owe on time and help reduce debt caused by late payments and errors.

Intermediation Roadmap

HMRC will publish an intermediation roadmap in spring ‌‌‌2027 setting out how HMRC will work with tax advisers, software providers and digital platforms to make it easier for taxpayers to get their tax right. It will include a new GOV.‌‌‌UK route to report harmful intermediary activity, helping customers make informed choices when choosing a tax adviser and working with partners to help clients claim expenses correctly.  
 
There will also be action to improve the way software supports customers to pay the right tax. Working closely with industry partners HMRC will introduce a registration process for software providers, enhanced standards, and a proportionate enforcement framework for addressing non-compliance.
