The Chancellor’s recent Autumn Budget introduced significant changes affecting business costs and personal tax burdens. Designed to balance fiscal responsibility with economic growth, the Budget revises multiple tax policies, including Employers’ National Insurance, Employment Allowance, Inheritance Tax, Non-Dom Taxation, Capital Gains Tax, and Corporation Tax. Below is an outline of these main changes and their implications.

Employers’ National Insurance (NI) and Employment Allowance

Employers’ National Insurance Contributions:

From April 2025, Employers’ National Insurance will rise from 13.8% to 15%, creating an additional expense for many businesses. Alongside this, the secondary threshold (the point above which employers must pay NI contributions for their employees) will decrease from £9,100 to £5,000. This combined increase in rate and threshold reduction will significantly impact payroll costs, particularly for larger businesses, though smaller firms may feel the effects as well.

Employment Allowance:

Employment Allowance remains available, enabling smaller businesses to offset some of their NI liabilities, but eligibility requirements are tightening. This allowance will continue to provide relief to smaller employers and charities, with an emphasis on reducing administrative burdens and supporting smaller businesses in sectors such as retail, care, and hospitality.

Inheritance Tax (IHT)

Changes to Inheritance Tax in the Budget aim to create a more progressive system, especially for high value estates. The nil rate band remains frozen, while the residence nil rate band now phases out more quickly for estates valued above £2 million. These adjustments mean that families with significant assets may face a greater tax liability upon inheritance, although exemptions, including those for assets left to spouses and charities, remain in place.

There is also an increased emphasis on encouraging high net worth individuals to consider alternative ways to transfer wealth, such as through lifetime gifts or by investing in IHT exempt assets. The Treasury has also announced a review to explore a simpler, fairer inheritance tax structure, indicating potential further changes in future budgets.

Non-Domiciled (Non-Dom) Taxation

The Budget significantly tightens rules around Non-Domiciled (Non-Dom) taxation, particularly for individuals who reside in the UK while claiming a permanent home abroad. The period during which an individual can claim Non-Dom status on a remittance basis has been shortened, with a new income threshold introduced. This requires high earning Non-Doms to begin paying UK taxes on their global income sooner, moving away from the previous 15year benefit.

These changes are designed to reduce the tax advantages for long-term non-domiciled residents and increase their tax contributions, aligning more closely with those of UK domiciled individuals.

Capital Gains Tax (CGT)

Changes to Capital Gains Tax include a reduction in the annual exempt amount, capturing a greater portion of capital gains for taxation. While CGT rates remain stable, the lower tax-free threshold will increase tax liabilities, particularly for those with high value assets such as property, shares, or other investments.

A clarification has also been made regarding disposals of residential property, with tighter regulations on second homes to ensure CGT applies appropriately. Business Asset Disposal Relief continues, albeit with more restrictive criteria for those with additional substantial income sources.

Corporation Tax

The main Corporation Tax rate remains unchanged, but new limitations are introduced on tax reliefs for larger companies, notably affecting R&D credits. This will impact firms with substantial profits and limit the extent to which they can offset tax through reliefs.

The government has also signalled a more stringent approach to profit shifting, with increased penalties for noncompliance. This measure, combined with targeted incentives for small and medium sized enterprises (SMEs), demonstrates the Budget’s focus on encouraging domestic growth while ensuring that larger, profitable multinationals pay a fairer share of UK taxes.

This Autumn Budget underscores the government’s intention to balance fiscal prudence with growth. For businesses, particularly those impacted by the Employers’ National Insurance increase and Employment Allowance changes, these measures mean that payroll planning, and tax strategies will need careful adjustment. Meanwhile, high net worth individuals and non-domiciled residents will likely need to review their tax positions in light of the changes to Inheritance Tax and Capital Gains Tax.

As these changes come into effect, businesses may benefit from consulting professional advisors, like CMA Accountancy, to navigate this shifting tax landscape efficiently. With increased costs looming, timely planning will be crucial in managing the new Budget impacts.
