Rumoured tax changes in the 2025 Autumn Statement

Whilst these are all predictions, the following changes are being rumoured for the 2025 Autumn Statement:

While these have not been confirmed, here are some of the main rumoured tax changes:

Income tax & National Insurance

  • Income tax: A proposed 2% increase across all income bands
  • Employee National Insurance: Corresponding 2% reduction in employee NI rates

Inheritance Tax (IHT) – lifetime gift cap

  • Introduction of a cap on tax-free lifetime gifts
  • Potential scrapping of taper relief, meaning gifts within seven years of death could be fully taxable

Capital Gains Tax (CGT) on main residences

A potential “mansion tax”, applying CGT to homes valued at over £1.5 million

Pension tax relief

Current band-based relief could be replaced with a flat rate of 25–30

National Insurance on rental income

Landlords may need to pay NICs on rental profits, bringing them in line with self-employed individuals

Stamp Duty reform

A potential shift of Stamp Duty Land Tax (SDLT) from buyers to sellers.

Preparing for change

The Autumn Statement often brings significant tax reforms, and this year could be no exception. Some of the potential changes, particularly around Inheritance Tax, pensions and property, could have a major impact on financial planning.
