Enter your figures below to see how much more tax you'll pay after Budget 2025
How this calculator works
This wizard shows how the 2025 Budget changes affect your tax position as a UK property investor. It does not calculate your total tax bill.
We compare your estimated tax before and after the Budget, using the same income and property information in both cases. This isolates the impact of the Budget itself.
What this tool includes
We model changes introduced by the 2025 Budget that affect:
- Rental income tax
- Dividend tax and personal tax band usage
- Capital Gains Tax when a property is sold
- Corporation tax for company-owned properties
Results show the difference between pre-Budget rules (2024–25) and post-Budget rules (from 2027–28) where changes apply.
What this tool does not include
This tool does not model:
- Property purchases or Stamp Duty
- Mortgage or financing calculations
- Investment forecasts or “what-if” scenarios
- Tax reliefs (e.g. Private Residence Relief, losses, rollover relief)
- Scotland-specific tax regimes
Assumptions
Dividend income for individuals is assumed to be £0 and is used only to assess tax band usage.
- For a full explanation of the policy changes and worked examples, see our Budget 2025 Analysis and Budget 2025 Wizard Manual.
