Business Asset Disposal Relief (BADR) Tax Increase to 18% – What It Means for You
March 19, 2026
From April 2026: Your Self-Assessment Will Ask More Questions About Your Company
March 20, 2026If you are thinking about transferring your sole trader or partnership business into a limited company, Business Incorporation Relief is something you need to understand—especially with changes coming from April 2026.
This relief has historically allowed business owners to incorporate without triggering an immediate Capital Gains Tax (CGT) bill. However, upcoming changes could affect how beneficial this relief is in practice.
What is Business Incorporation Relief?
Business Incorporation Relief allows you to transfer your business into a limited company in exchange for shares, without paying CGT at the point of transfer.
Instead of paying tax immediately:
- The gain is deferred
- The value is rolled into the shares
- CGT becomes payable only when you sell those shares
This has made incorporation a popular strategy for:
- Sole traders scaling up
- Partnerships restructuring
- Property businesses moving into company structures
What’s Changing from April 2026?
From 6 April 2026, there will be important changes to how Incorporation Relief under Section 162 TCGA 1992 operates. While the relief itself is not being abolished, the way it is accessed and the wider tax environment around it are changing, which could reduce its overall effectiveness and increase compliance requirements.
1. Relief Will No Longer Apply Automatically
Currently, Incorporation Relief is applied automatically where the qualifying conditions are met. However, from April 2026, landlords and business owners will be required to make an active claim for the relief.
This change is outlined in the Government’s policy paper titled “Capital Gains Tax: Incorporation Relief claims.” It means:
- Relief will not be granted by default
- A formal claim must be submitted within the relevant time limits
- Additional documentation and evidence may be required to support the claim
This increases the administrative burden and the risk of missing out on relief if not properly claimed.
2. Increased HMRC Scrutiny
HMRC is expected to take a more robust approach when reviewing Incorporation Relief claims, particularly in relation to property businesses.
Key areas of focus will include:
- Whether the activity genuinely constitutes a “business” rather than passive investment
- The level of landlord involvement (e.g. active management vs minimal input)
- Whether incorporation is being undertaken for genuine commercial reasons rather than primarily for tax advantages
This means borderline cases, especially buy-to-let portfolios, are more likely to be challenged.
This is particularly relevant for:
- Buy-to-let landlords
- Property portfolios with minimal activity
Does Incorporation Still Make Sense?
It depends on your situation.
Incorporation Relief can still be valuable if:
- You are running a genuine trading business
- You plan to retain profits within the company
- You are thinking long-term growth and reinvestment
However, it may not be suitable if:
- You need regular income personally
- SDLT costs outweigh the benefits
- Your structure does not meet HMRC’s definition of a business
Key Planning Points Before April 2026
If you are considering incorporation, now is the time to act:
✔ Review whether your activity qualifies as a business
✔ Consider timing before further tax changes take effect
✔ Model CGT vs Corporation Tax vs SDLT
✔ Plan how you will extract profits efficiently
Final Thoughts
Business Incorporation Relief remains a powerful tool—but it is no longer a “one size fits all” solution.
With rising tax rates and increased HMRC scrutiny, careful planning is essential to ensure incorporation actually benefits you.
