Autumn Budget 2025: three key takeaways for businesses

Autumn Budget 2025 finally put an end to months of speculation, but what were the major announcements for businesses? We've picked out three areas of particular interest below:

EMI limits increased

From April 2026, access to tax-advantaged EMI options will be significantly expanded by increasing key eligibility thresholds:

• the overall limit on company options will double from £3 million to £6 million
• the gross assets threshold will quadruple from £30 million to £120 million
• the employee headcount limit will increase from 250 to 500 employees.

The limit on the exercise period of EMI options will also be increased from 10 to 15 years. Existing qualifying options granted before April 2026 (which have not been exercised or expired) can also be amended to extend their life without losing their tax-advantaged status.

These changes create an exciting opportunity for growing companies, including those who have previously outgrown EMI, to offer attractive, tax-advantaged incentives to their employees.

Backing the UK's entrepreneurs

Recognising the potential of the UK's start-up ecosystem, the government launched the most comprehensive review of tax support for entrepreneurs in years, as well as publishing its Entrepreneurship Prospectus (setting out its ambitions for founders).

In the meantime, the annual, lifetime and gross assets limits for the EIS and VCT schemes will be doubled from April 2026. The new limits are set out in the table below. This is, however, tempered by the reduction in the upfront VCT income tax relief from 30% to 20%.

Stamp taxes on shares

The government announced a significant step in the long-awaited modernisation of stamp taxes on shares, which ultimately aims to replace both stamp duty and SDRT with a single 'securities transfer charge'. The changes proposed enable the government to test a new digital service for self-assessing and paying stamp duty and SDRT.

In addition, a new exemption from the 0.5% SDRT charge on agreements to transfer securities of companies has been introduced from 27 November 2025. It applies to companies that are newly listed on UK regulated markets and covers a period of three years from listing. This aims to make the UK a more attractive place to list.
