With You At Every Stage
The Chancellor has delivered her 2025 Budget, and let’s be honest — it’s one of the biggest shake-ups we’ve seen in years.
There’s no hiding it: taxes are going up, savings allowances are being trimmed, and the government is shifting more of the burden onto wealth, property, and passive income.
But what does this actually mean for you — the business owner, the saver, the landlord, the everyday taxpayer?
Let’s break it down in a clean, human way.
For years, income from rent, dividends, and savings has been taxed lower than wages.
This Budget starts to close that gap.
Tax on savings interest
Tax on dividends
Tax on rental income
A new tax on properties over £2 million
Personal tax thresholds frozen for longer (a “stealth tax”)
Because even if your income stays the same, you’ll pay more tax automatically as inflation pushes you into higher brackets.
For many families, ISAs were the easiest way to save tax-free.
Now:
ISA allowances for under-65s are being reduced
Tax on savings interest is increasing
If you save money in the bank — this affects you directly.
Landlords are going to feel this Budget.
What’s changing:
Higher tax on rental profits
Lower relief on certain costs
High-value homes (£2m+) facing a new “mansion-style” tax
For some landlords, the numbers may no longer stack up.
Portfolio restructuring is going to become essential — not optional.
If you use salary sacrifice for pensions (or benefits like EVs, private healthcare etc.)
Expect:
New limits
Possible reductions in tax advantages
Higher administrative charges
Many people will need to rethink pension strategy going forward.
You may be wondering: Why are they doing this?
The aim is to:
Raise £26 billion
Create fiscal headroom
Support welfare changes (e.g., removing the two-child cap)
Make taxation “fairer” between workers and asset-holders
Stabilise long-term UK finances
Whether you agree or not — this is the direction of travel.
