Have you ever wondered why a property developer might own 15 separate limited companies, each holding just one house? The answer is the SPV (Special Purpose Vehicle), a limited company created for a single, defined purpose, designed to wall off financial risk from the rest of a business or an individual's affairs.

The most common use of an SPV for UK business owners is in company sales, but the mechanics are often misunderstood. Consider a software company with £180,000 of annual profit being sold. If the owner sells the company's shares directly, they pay Capital Gains Tax on the entire gain, with Business Asset Disposal Relief (BADR) taxing the first £1m of gains at 14% in 2025/26 (rising to 18% from 6 April 2026). However, if the buyer only wants the assets (the intellectual property, client contracts, and staff) and not the company shell, a direct asset sale would be taxed as income, not capital. The SPV solves this: the owner sells the assets into a newly formed SPV, then sells the SPV's shares to the buyer. This preserves access to BADR, but only if the SPV is set up before any commercial negotiations begin. HMRC's "pre-ordained" anti-avoidance rules will deny the relief if the structure is created solely to avoid tax.

Beyond exits, SPVs are critical for independent retailers and hospitality operators who own their premises. A restaurant group might transfer its freehold property into an SPV. If the trading company later fails, the property is protected from the group's creditors. The SPV pays corporation tax on rental income at 19% (if profits are under £50,000) or 25% (if over £250,000), and the rent must be at a commercial rate to avoid a "transfer pricing" challenge from HMRC.

Common pitfalls that catch business owners out:

  • Substance over form: HMRC can disregard an SPV if it has no bank account, no separate trading activity, and no economic substance. It must be capitalised with real cash or assets, not just a paper entry.
  • VAT grouping: If your main company and the SPV are under common control, you can apply for VAT grouping so the SPV does not need its own VAT registration even if its turnover exceeds £90,000 (the threshold from April 2024). Without grouping, the SPV must register and charge VAT separately.
  • Dividend extraction: Taking profits from the SPV as dividends triggers personal tax. The dividend allowance is £500 for 2025/26, with tax at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate). A director's loan from the SPV to you would be taxed under the beneficial loan rules and could trigger a Section 455 charge at 33.75%.

An SPV is not a tax avoidance scheme. It is a legitimate structural tool for isolating risk, simplifying future sales, and, where appropriate, securing capital gains relief. But HMRC is alert to SPVs used purely to convert income into capital gains. Professional advice is essential before setting one up, particularly on the timing, capitalisation, and the specific reliefs available for your circumstances.
