What is Form CG34? : Post Transaction Valuation Checks for Capital Gains

When it comes to paying taxes, understanding the intricacies of the process can be daunting. One such area that often raises questions is the capital gains tax (CGT) and the valuation of assets post-transaction. In the United Kingdom, the HM Revenue & Customs (HMRC) requires taxpayers to report and pay capital gains tax on the sale of certain assets. To help with this process, Form CG34 is provided as a means of requesting a post-transaction valuation check. In this article, we will delve into the details of Form CG34, its purpose, and the process of submitting it.

What is Form CG34?

What is Form CG34?

Form CG34, or the Post Transaction Valuation Check (PTVC) form, is a document provided by the HMRC to assist taxpayers in determining the value of an asset after it has been sold or disposed of. This valuation check is essential for accurately calculating capital gains tax liability. Form CG34 is used when there is a significant difference in the value of an asset between the time it was acquired and the time it was disposed of, and the taxpayer requires HMRC's assistance in determining the appropriate valuation for CGT purposes.

Why Request a Post Transaction Valuation Check?

Certainty: A post-transaction valuation check can provide assurance regarding the correct valuation of an asset, which is necessary for accurately calculating capital gains tax. If the HMRC agrees with the submitted valuation, the taxpayer can confidently report the capital gains tax without fearing an inaccurate calculation.

Avoiding Penalties: If a taxpayer underestimates the value of an asset and consequently underpays the capital gains tax, they may face penalties and interest charges. By requesting a post-transaction valuation check, the taxpayer can minimize the risk of such penalties.

Resolving Disputes: In some cases, disputes may arise between taxpayers and the HMRC regarding the valuation of assets. A post-transaction valuation check can help resolve these disputes by providing a clear, agreed-upon value for the asset in question.

How to Submit Form CG34?

Before submitting Form CG34, it is essential to ensure that the transaction in question falls within the scope of capital gains tax. Form CG34 should be submitted after the transaction has taken place and before the CGT return is filed.

Obtain the Form: The first step is to download Form CG34 from the HMRC website. It can be found in the 'Forms' section under 'Capital Gains Tax.'

Complete the Form: Fill out the form with the required information, including details about the asset, the acquisition and disposal dates, the cost of the asset, the disposal proceeds, and the taxpayer's proposed valuation.

Provide Supporting Evidence: Along with the completed form, the taxpayer must provide supporting evidence to justify their proposed valuation. This may include documents such as professional valuations, comparable sales data, or any other relevant information that supports the valuation.

Submit the Form: Once completed and accompanied by the necessary evidence, the form should be submitted to the HMRC. The mailing address for submission can be found on the form itself.

How to Complete Different Sections of Form CG34

Form CG34, or the Post Transaction Valuation Check (PTVC) form, is a document provided by the HM Revenue & Customs (HMRC) in the United Kingdom to help taxpayers determine the value of an asset after it has been sold or disposed of for capital gains tax (CGT) purposes. In this article, we will walk you through the process of completing different sections of Form CG34, ensuring you submit an accurate and well-supported valuation request to the HMRC.

Section 1: Taxpayer Details

In this section, provide your personal details to identify yourself as the person requesting the valuation check. Fill in your name, address, National Insurance number, and the unique taxpayer reference (UTR) if applicable. If you are acting as an agent on behalf of the taxpayer, provide your client's details and your agent reference number.

Section 2: Asset Details

This section requires you to provide comprehensive information about the asset for which you are requesting a post-transaction valuation check.

Description of The Asset: Describe the asset in sufficient detail, including any distinguishing features or characteristics. For example, if it is a property, mention the address, type of property (e.g., detached house, flat), and any unique features (e.g., garden, garage).

Date of Acquisition: Enter the date you acquired the asset. This is crucial for determining the duration of ownership and calculating capital gains tax.

Date of Disposal: Enter the date you disposed of the asset. This information will be used to establish the period between acquisition and disposal for CGT calculation purposes.

Acquisition Cost: Provide the total cost of acquiring the asset, including any associated expenses such as fees or taxes.

Disposal Proceeds: Enter the amount received when you sold or disposed of the asset.

Section 3: Proposed Valuation

In this section, you will provide your proposed valuation of the asset and justify it with relevant evidence.

Taxpayer's Proposed Valuation: Enter the value you believe is accurate for the asset at the time of disposal. This figure will be used to calculate your capital gains tax liability.

Reasons for The Proposed Valuation: Explain the basis for your proposed valuation. You may refer to factors such as market conditions, comparable sales, or professional valuations. Be specific and concise in your explanation.

Section 4: Supporting Evidence

This section is crucial for ensuring that your proposed valuation is accepted by the HMRC. Provide robust supporting evidence to substantiate your valuation.

Professional Valuation: If you have obtained a professional valuation from a qualified expert, attach a copy of the report. This is often the most persuasive form of evidence.

Comparable Sales: If your proposed valuation is based on comparable sales, provide details of similar assets that have been sold in the same area and timeframe. Include the address, sale price, and date of sale for each comparable property.

Other Relevant Evidence: You may also attach any other relevant information that supports your proposed valuation. This could include documents such as planning permissions, structural surveys, or photographs of the asset.

Section 5: Declaration

Finally, you must sign and date the declaration at the end of the form, confirming that the information provided is accurate and complete to the best of your knowledge. If you are an agent acting on behalf of the taxpayer, make sure your client reviews the form and signs the declaration as well.

Completing Form CG34 accurately and thoroughly is essential for obtaining a reliable post-transaction valuation check from the HMRC. By following this guide and providing comprehensive information and supporting evidence, you can increase the likelihood of a favorable outcome and avoid potential penalties or disputes related to capital gains tax. Remember to

What Happens After Submission?

Upon receiving the completed Form CG34 and supporting evidence, the HMRC will review the submitted documents and provide a response. If the HMRC agrees with the proposed valuation, they will issue a confirmation letter stating their agreement. This letter can then be used as evidence when filing the capital gains tax return.

If the HMRC disagrees with the proposed valuation, they may request additional information or propose an alternative valuation. In such cases, the taxpayer and the HMRC may negotiate to reach a mutually agreeable valuation. If no agreement can be reached, the taxpayer may choose to seek professional advice to get it done which is usually a very good idea.

Exploring Strategies to Minimize or Avoid Capital Gains Tax in the UK

Capital gains tax (CGT) is a tax levied on the profit made from the sale or disposal of an asset, such as property, shares, or valuable items. While it is a mandatory obligation for UK taxpayers, there are legal strategies that can be employed to minimize or even avoid CGT in certain circumstances. In this article, we will discuss various methods for reducing capital gains tax liability in the UK.

Utilize the Annual Exempt Amount

Each taxpayer in the UK has an annual exempt amount, which is a tax-free allowance for capital gains. For the tax year 2021-2022, the annual exempt amount is £12,300 for individuals and £6,150 for trustees. By realizing gains within this limit, you can avoid paying capital gains tax on those gains.

Transfer Assets to Your Spouse or Civil Partner

Transferring assets between spouses or civil partners does not trigger CGT, as these transfers are considered "no gain, no loss" transactions. By transferring assets to your spouse or civil partner, you can effectively double the tax-free allowance for capital gains, as both you and your spouse or civil partner will have an annual exempt amount. It is essential to note that this strategy is not applicable to transfers between unmarried partners or cohabitants.

Offset Capital Gains with Capital Losses

If you have incurred capital losses in the same tax year or previous years, you can offset these losses against your capital gains to reduce your overall CGT liability. To utilize this strategy, you must report your capital losses to HM Revenue & Customs (HMRC) and make a claim to offset your gains.

Take Advantage of Tax Relief Schemes

The UK government offers several tax relief schemes designed to encourage investment and entrepreneurship. By investing in qualifying assets or businesses, you may be able to minimize or avoid capital gains tax. Some popular tax relief schemes include:

Enterprise Investment Scheme (EIS): This scheme offers CGT deferral relief for investments in qualifying small and medium-sized enterprises. By reinvesting gains from the sale of other assets into EIS-eligible companies, you can defer CGT until you sell the EIS shares.

Seed Enterprise Investment Scheme (SEIS): Similar to the EIS, the SEIS provides CGT relief for investments in early-stage companies. By reinvesting gains into SEIS-eligible companies, you can claim 50% CGT relief on the reinvested amount, up to a maximum annual investment limit of £100,000.

Business Asset Disposal Relief (formerly Entrepreneurs' Relief): This relief is available to individuals selling qualifying business assets, such as shares in their trading company. Eligible taxpayers can benefit from a reduced CGT rate of 10% on qualifying gains, up to a lifetime limit of £1 million.

Hold onto Assets for the Long Term

Capital gains tax rates in the UK are lower for long-term investments. By holding onto assets for a longer period, you may be able to benefit from reduced CGT rates. For example, the CGT rate for higher-rate taxpayers is 28% for residential property and 20% for other assets. By contrast, the CGT rate for basic-rate taxpayers is 18% for residential property and 10% for other assets.


While it may not be possible to completely avoid capital gains tax in the UK, various strategies can help minimize your CGT liability. By utilizing the annual exempt amount, transferring assets to a spouse or civil partner, offsetting capital gains with capital losses, taking advantage of tax relief schemes, and holding onto assets for the long term, you can potentially reduce the payable Capital Gains Tax.
