The UK Spring Budget 2026, presented by Rachel Reeves on 3rd March 2026, did not introduce any new tax increases.
However, it confirms several important updates that will affect individuals, business owners, and companies across the UK.
Instead of raising tax rates, the government is focusing on:
- Freezing tax thresholds
- Increasing compliance
- Moving towards digital tax systems
Personal Tax: What You Need to Know
Income Tax Thresholds Frozen
- Personal allowance remains £12,570
- Freeze extended until April 2031
What this means:
As your income increases, you may end up paying more tax or moving into a higher tax bracket—even if tax rates don’t change. This is called fiscal drag.
Example:
Let’s say your salary is £30,000 in 2026, and it increases to £35,000 by 2028 due to annual raises.
Even though tax rates haven’t changed, the personal allowance stays frozen at £12,570. This means a larger portion of your income becomes taxable over time.
- In 2026: Taxable income = £30,000 − £12,570 = £17,430
- In 2028: Taxable income = £35,000 − £12,570 = £22,430
As a result, you pay more tax simply because your income increased while the tax-free allowance stayed the same.
If your income rises further, you could even move into a higher tax bracket, increasing your tax rate as well.
Impact on Pensioners
The Office for Budget Responsibility (OBR) expects the state pension to exceed the personal allowance by 2027- 28.
This could mean more pensioners may need to pay income tax in the future.
Dividend Tax Increase
From 2026:
- Basic rate: 10.75% (up from 8.75%)
- Higher rate: 35.75% (up from 33.75%)
This mainly affects:
- Company directors
- Business owners
- Shareholders
If you take income as dividends, you will likely pay more tax.
Making Tax Digital (MTD)
From April 2026, Making Tax Digital (MTD) will become mandatory for:
- Self-employed individuals
- Landlords with annual income over £50,000
The government is introducing MTD in phases, gradually lowering the income threshold each year:
- From April 2026: Applies to those earning over £50,000
- From April 2027–28: Threshold reduces to over £30,000
- From April 2028 onwards: Expected to include those earning over £20,000
What this means:
If your total income from self-employment or property exceeds these thresholds, you’ll need to:
- Keep digital records of your income and expenses
- Submit quarterly updates to HMRC
- File your tax return using MTD-compatible software
You must:
- Keep digital records
- Submit quarterly updates to HMRC
This is a major shift toward fully digital tax reporting.
Corporation Tax: Key Updates
Tax Rates Stay the Same
- Main rate: 25%
- Small profits rate: 19%
This gives businesses stability, but no new tax reliefs or incentives.
Late Filing Penalties Increasing
From April 2026:
- Penalties for late corporation tax returns will double
Businesses must improve deadline management and compliance.
Capital Allowances Reduced
- Writing-down allowance reduced to 14% (from 18%)
Impact:
- Slower tax relief on business investments
- May affect cash flow and planning decisions
Finance Bill Amendments (Still in Progress)
Some important proposals are still being reviewed:
Offshore Income Gains (OIG)
- Changes to how offshore investment gains are taxed
Inheritance Tax Updates
- Changes to business property relief
- Impact on family business succession planning
These are not final yet—businesses should monitor updates closely.
Temporary Repatriation Facility (TRF)
- Allows former non-UK residents to bring overseas income into the UK at lower tax rates
- Available until 2027–28
The Bigger Picture
According to the Office for Budget Responsibility:
- UK tax burden expected to rise from 34.5% to 38.5% of GDP by 2030
- Highest level since World War II
Key takeaway:
The government is increasing tax revenue without increasing tax rates directly.
