Budget 2025 predictions: What could be on the horizon?

20th October 2025

With the Budget due to be announced on 26th November 2025, speculation is growing about what is likely to be announced. In this article, Rowleys tax and payroll experts share their key Budget 2025 predictions.

Personal tax and National Insurance Contributions (NICs)

We may see the freeze on income tax allowances and National Insurance thresholds extended beyond April 2028. This would mean that as wages increase, more workers are gradually drawn into higher tax bands, a process often referred to as “fiscal drag.”

There is also talk of a 1–2% reduction in employee NIC rates, paired with a corresponding increase in the basic rate of income tax (currently 20%).

While this might initially sound like a tax cut, the aim appears to be to collect more revenue from individuals with property income and pensioners who do not usually pay NICs. Employees would see little change to their overall take-home pay, but those with additional income sources could end up paying more.

Individual Savings Accounts (ISAs)

The annual ISA limit of £20,000 has remained unchanged since 2017, and this year’s Budget could finally bring a shift.

One possibility is a reduction in the overall tax-free ISA limit, though it may instead apply specifically to the cash ISA component, keeping the stocks and shares ISA unchanged.

This move would align with the government’s focus on encouraging longer-term investment over cash savings.

Capital Gains Tax (CGT)

Capital Gains Tax could be an area of significant reform. Potential changes include:

If implemented, these measures would mark one of the most substantial overhauls of capital taxation in recent years.

Value Added Tax (VAT)

A reduction of the VAT registration threshold to £30,000 is a strong possibility.

This would mean more small businesses being required to register for VAT, aligning the threshold with the new Making Tax Digital (MTD) limit, which drops to £30,000 from April 2027.

While this could increase the administrative burden on microbusinesses, it may also encourage digital recordkeeping and compliance across the board.

Inheritance Tax (IHT) and Reliefs

The government could tighten existing IHT rules, particularly around lifetime gifts, by:

On a more positive note, there may be an increase in the limit for Agricultural and Business Property Relief (APR/BPR) to £5 million, supporting family-owned and rural enterprises.

Tax Partner, Mark Hook, comments: “After several years of speculation about Inheritance Tax reform, the government may now focus on tightening reliefs rather than cutting rates, reinforcing the importance of early estate planning.”

Pensions

Pension reform remains high on the agenda. Potential measures could include:

Any of these moves would reshape retirement planning and could significantly impact higher earners.

Stamp Duty and property taxation

One of the more radical proposals under discussion is abolishing Stamp Duty Land Tax (SDLT) and replacing it with a Property Value Tax (sometimes dubbed a “Mansion Tax”).

This would involve an annual charge on high-value properties rather than a one-off payment at purchase. Alongside this, council tax reform may also be introduced to modernise the property taxation system.

Excise duties and cost of living measures

We expect to see increases in duties on petrol and gambling as part of the government’s wider health and environmental agenda.

Meanwhile, pay-related measures could include:

Employers could also see NIC threshold adjustments and a possible increase to the Employment Allowance from £10,500 to £12,000, providing some relief for smaller businesses.

Additionally, auto-enrolment reforms (long discussed) may finally be confirmed, lowering the minimum age to 18 and removing the lower earnings limit.

The Budget 2025 – What happens next?

With speculation mounting, this Budget is likely to focus on broadening the tax base and simplifying reliefs, rather than introducing sweeping tax cuts.

As always, we’ll be analysing the announcements in full when the Chancellor delivers the Budget, outlining what they mean for individuals and businesses alike.
