Introduction

Incorporation is a significant milestone for many businesses. It offers numerous advantages, including personal asset protection, lower corporate tax rates, and easier access to capital. For many sole traders and partnerships, incorporating their business is a natural progression. However, one of the most powerful tools available for business owners considering this step is Incorporation Relief—a tax relief that can defer Capital Gains Tax (CGT) when transferring a business to a limited company.

The 2025 UK Budget introduces a crucial change to Incorporation Relief, making it essential for business owners, tax advisors, and accountants to fully understand the new process. As of 6 April 2026, Incorporation Relief will no longer apply automatically. Instead, business owners must actively claim the relief, which could significantly impact tax planning strategies for many businesses.

In this comprehensive guide, we will explore what Incorporation Relief is, the recent changes introduced in the 2025 Budget, the eligibility criteria, how to claim the relief, and how it can benefit your business. Additionally, we will answer some of the most frequently asked questions on the subject, and provide insights into the steps you need to take to ensure that you are taking full advantage of this valuable tax relief.

What is Incorporation Relief?

Incorporation Relief allows sole traders or partnerships in the UK to transfer their business to a limited company without triggering immediate Capital Gains Tax (CGT) on the transfer of business assets. The relief defers CGT, meaning that the tax liability is not triggered at the time of the transfer. Instead, the gain is “rolled over” and applied to the shares that the business owner receives in the new limited company.

Incorporation Relief works by treating the business transfer as a tax-neutral event. The business assets, which might include goodwill, intellectual property, and physical assets like equipment or property, are transferred to the company. The capital gain on these assets is deferred, and CGT is only payable when the business owner eventually sells the shares in the company.

How Does Incorporation Relief Work?

When a business is incorporated, the assets are transferred to the new company. If Incorporation Relief applies, the transfer of these assets will not trigger CGT immediately. Instead, the deferred tax is applied to the new company’s shares, meaning that the business owner’s CGT liability is deferred until the sale of those shares.

For example, if a sole trader transfers a business valued at £300,000 (with £100,000 of goodwill) into a company, the transfer may qualify for Incorporation Relief. The £200,000 gain is deferred, and the base cost of the shares in the company will be reduced by the deferred amount. CGT will only be paid when the shares are sold, possibly at a later date when the value of the business has increased further.

What Does This Mean for Business Owners?

Incorporation Relief is an attractive option for business owners looking to transition from a sole trader or partnership structure to a limited company without immediately incurring a CGT liability. However, the process has become more complex with the 2025 Budget’s announcement that business owners will need to actively claim the relief starting 6 April 2026.

Changes to Incorporation Relief from 6 April 2026

Under the current UK tax law (Section 162 of the Taxation of Chargeable Gains Act 1992), Incorporation Relief has applied automatically as long as certain conditions were met. However, with the introduction of new rules from 6 April 2026, business owners will now be required to make an active claim for the relief. This change has significant implications for both business owners and their advisors, as missing the claim could result in unexpected CGT liabilities.

The New Claim Process

Starting from 6 April 2026, if a sole trader or partnership transfers assets to a company, they will need to make a formal claim for Incorporation Relief through their Self-Assessment tax return for the relevant tax year. The key details required for the claim will include:

• A description of the transaction
• Details of the business being transferred
• The tax computations for the assets being transferred

This is a critical change because if the claim is not made, the transfer may be treated as a disposal at market value, which could result in an immediate CGT charge.

Why is the Process Changing?

According to the government, the change aims to improve HMRC’s data on business transfers and to target compliance resources more effectively. By requiring businesses to actively claim the relief, HMRC will have better visibility into the transactions and can better ensure that the rules are being followed.

Eligibility for Incorporation Relief

Incorporation Relief is available to business owners in the UK who meet certain criteria. The key eligibility conditions include:

1. Transfer of a Business as a Going Concern

• The business being transferred must be an operational business that is capable of continuing after the transfer.
• For example, a retail business must transfer all operational assets, including stock, goodwill, equipment, and intellectual property.

2. Transfer of All Assets (Except Cash)

• To qualify, the business owner must transfer all the assets needed to operate the business, excluding cash. Cash reserves can be retained personally without affecting the eligibility for Incorporation Relief.

3. Payment Must Be in Shares

• The payment for the business assets must be made in the form of shares in the newly incorporated company. If the payment includes any cash portion, the business owner will have to pay CGT on that portion.

4. Sole Traders or Partnerships

• Incorporation Relief applies to sole traders and partnerships transferring their business to a limited company.

5. Property Businesses

• Property businesses can also benefit from Incorporation Relief, but the property business must qualify as a genuine business rather than a passive investment.

Conditions for Claiming Incorporation Relief

As with any tax relief, Incorporation Relief comes with specific conditions that must be met for the claim to be valid. Some of the key conditions for claiming Incorporation Relief include:

• Full Transfer of Business Assets: The business must be transferred as a going concern, and all operational assets must be included in the transfer.
• Consideration in Shares: The business owner must receive shares in the company as consideration for the business assets. Cash payments are allowed, but they will trigger CGT on the cash portion.
• Exclusion of Cash: Cash or liquid assets can be retained by the business owner but must not form part of the transfer.
• Detailed Documentation: Detailed records of the transaction, assets, and tax computations must be submitted with the Self-Assessment tax return.

How to Apply for Incorporation Relief

The process for applying for Incorporation Relief is straightforward but requires careful attention to detail. Below are the steps involved in applying for the relief:

1. Transfer Your Business to a Limited Company

• Transfer all operational assets (excluding cash) from your sole trader or partnership business to the new company.
• Ensure that the company is a going concern and capable of continuing operations after the transfer.

2. Prepare the Necessary Documentation

• Ensure that you have all the necessary documents, including descriptions of the business and the assets being transferred, as well as the tax computations for the business assets.

3. Submit a Self-Assessment Tax Return

• To claim Incorporation Relief, you will need to submit a Self-Assessment tax return for the year in which the transfer takes place. The claim must include the necessary information, including the details of the transfer, the business, and the assets involved.

4. Involve a Tax Adviser Early

• The process of incorporating a business and claiming Incorporation Relief can be complex, especially if you have multiple assets, partners, or property interests. It’s recommended that you consult with a tax adviser to ensure that all conditions are met and the claim is made correctly.
