What Is Capital Gains Tax in the UK?

Capital gains tax in the UK applies to the profit made when selling or “disposing of” an asset that has increased in value. This includes real estate, shares, and business holdings. For corporate entities, capital gains may be taxed under UK corporation tax rules, while individuals (such as U.S.-based developers or private investors) may be directly liable for CGT.

For foreign investors, the UK government requires non-residents to report and pay tax on gains from UK property—even if they are not physically present. This is where the expertise of a capital gains tax accountant based in London becomes vital.


How a Capital Gains Tax Accountant in London Adds Value

For U.S. construction companies, having a London-based CGT accountant offers the following key benefits:

  1. UK Tax Compliance: These professionals ensure that gains from property sales or project divestitures are correctly reported to HMRC. They handle all necessary filings and deadlines, such as the 60-day reporting rule for non-resident property disposals.
  2. Strategic Structuring: A seasoned accountant helps American contractors structure investments to limit unnecessary tax burdens. For example, they may recommend forming a UK-registered company or using joint venture arrangements to optimize tax outcomes.
  3. Coordination with U.S. Tax Rules: Since the U.S. taxes global income, any gain realized in the UK may also be reportable to the IRS. A UK-based CGT accountant often works in tandem with U.S. tax advisors to prevent double taxation through credits or exemptions permitted under the UK-U.S. tax treaty.
  4. Maximizing Allowable Reliefs: UK tax law provides several reliefs, such as Business Asset Disposal Relief or Private Residence Relief (when applicable), which can reduce the CGT burden. A specialist accountant ensures that all eligible exemptions are applied.

Construction-Focused Scenarios

Take, for example, a New York-based construction firm that completed a commercial redevelopment project in East London and plans to sell its stake. Without careful tax planning, a significant portion of the profit may be lost to capital gains tax. A London-based CGT accountant could assess the gain, apply any allowable reliefs, and prepare accurate filings—ensuring the company retains maximum post-tax returns.

In another case, a U.S. subcontractor selling construction equipment or intellectual property rights related to a UK project would also benefit from tax guidance to assess whether CGT or corporate tax applies and how to document the transaction for both UK and U.S. tax reporting.


Long-Term Financial Planning

A capital gains tax accountant in London does more than just handle tax at the point of sale. They offer ongoing advice to help construction firms plan asset purchases, ownership structures, and exit strategies—critical for long-term success.
